FamilyTreeDNA Relaunch – New Feature Overview

The brand-new FamilyTreeDNA website is live!

I’m very pleased with the investment that FamilyTreeDNA has made in their genealogy platform and tools. This isn’t just a redesign, it’s more of a relaunch.

I spoke with Dr. Lior Rauchberger, CEO of myDNA, the parent company of FamilyTreeDNA briefly yesterday. He’s excited too and said:

“The new features and enhancements we are releasing in July are the first round of updates in our exciting product roadmap. FamilyTreeDNA will continue to invest heavily in the advancement of genetic genealogy.”

In other words, this is just the beginning.

In case you were wondering, all those features everyone asked for – Lior listened.

Lior said earlier in 2021 that he was going to do exactly this and he’s proven true to his word, with this release coming just half a year after he took the helm. Obviously, he hit the ground running.

A few months ago, Lior said that his initial FamilyTreeDNA focus was going to be on infrastructure, stability, and focusing on the customer experience. In other words, creating a foundation to build on.

The new features, improvements, and changes are massive and certainly welcome.

I’ll be covering the new features in a series of articles, but in this introductory article, I’m providing an overview so you can use it as a guide to understand and navigate this new release.

Change is Challenging

I need to say something here.

Change is hard. In fact, change is the most difficult challenge for humans. We want improvements, yet we hate it when the furniture is rearranged in our “room.” However, we can’t have one without the other.

So, take a deep breath, and let’s view this as a great new adventure. These changes and tools will provide us with a new foundation and new clues. Think of this as finding long-lost documents in an archive about your ancestors. If someone told me that there is a potential for discovering the surname of one of my elusive female ancestors in an undiscovered chest in a remote library, trust me, I’d be all over it – regardless of where it was or how much effort I had to expend to get there. In this case, I can sit right here in front of my computer and dig for treasure.

We just need to learn to navigate the new landscape in a virtual room. What a gift!

Let’s start with the first thing you’ll see – the main page when you sign in.

Redesigned Main Page

The FamilyTreeDNA main page has changed. To begin with, the text is darker and the font is larger across the entire platform. OMG, thank you!!!

The main page has been flipped left to right, with results on the left now. Projects, surveys, and other information, along with haplogroup badges are on the right. Have you answered any surveys? I don’t think I even noticed them before. (My bad!)

Click any image to enlarge.

The top tabs have changed too. The words myTree and myProjects are now gone, and descriptive tabs have replaced those. The only “my” thing remaining is myOrigins. This change surprises me with myDNA being the owner.

The Results & Tools tab at the top shows the product dropdowns.

The most popular tabs are shown individually under each product, with additional features being grouped under “See More.”

Every product now has a “See More” link where less frequently used widgets will be found, including the raw data downloads. This is the Y DNA “See More” dropdown by way of example.

You can see the green Updated badge on the Family Finder Matches tab. I don’t know if that badge will always appear when customers have new matches, or if it’s signaling that all customers have updated Family Finder Matches now.

We’ll talk about matches in the Family Finder section.

The Family Finder “See More” tab includes the Matrix, ancientOrigins, and the raw data file download.

The mitochondrial DNA section, titled Maternal Line Ancestry, mtDNA Results and Tools includes several widgets grouped under the “See More” tab.

Additional Tests and Tools

The Additional Tests and Tools area includes a link to your Family Tree (please do upload or create one,) Public Haplotrees, and Advanced Matches.

Public haplotrees are free-to-the-public Y and mitochondrial DNA trees that include locations. They are also easily available to FamilyTreeDNA customers here.

Please note that you access both types of trees from one location after clicking the Public Haplotrees page. The tree defaults to Y-DNA, but just click on mtDNA to view mitochondrial haplogroups and locations. Both trees are great resources because they show the location flags of the earliest known ancestors of the testers within each haplogroup.

Advanced Matches used to be available from the menu within each test type, but since advanced matching includes all three types of tests, it’s now located under the Additional Tests and Tools banner. Don’t forget about Advanced Matches – it’s really quite useful to determine if someone matches you on multiple types of tests and/or within specific projects.

Hey, look – I found a tooltip. Just mouse over the text and tabs on various pages to see where tooltips have been added.

Help and Help Center

The new Help Center is debuting in this release. The former Learning Center is transitioning to the Help Center with new, updated content.

Here’s an example of the new easy-to-navigate format. There’s a search function too.

Each individual page, test type, and section on your personal home page has a “Helpful Information” button.

On the main page, at the top right, you’ll see a new Help button.

Did you see that Submit Feedback link?

If you click on the Help Center, you’ll be greeted with context-sensitive help.

I clicked through from the dashboard, so that’s what I’m seeing. However, other available topics are shown at left.

I clicked on both of the links shown and the content has been updated with the new layout and features. No wonder they launched a new Help Center!

Account Settings

Account settings are still found in the same place, and those pages don’t appear to have changed. However, please keep in mind that some settings make take up to 24 hours to take effect.

Family Finder Rematching

Before we look at what has changed on your Family Finder pages, let’s talk about what happened behind the scenes.

FamilyTreeDNA has been offering the Family Finder test for 11 years, one of two very early companies to enter that marketspace. We’ve learned so much since then, not only about DNA itself, but about genetic genealogy, matching, triangulation, population genetics, how to use these tools, and more.

In order to make improvements, FamilyTreeDNA changing the match criteria which necessitated rematching everyone to everyone else.

If you have a technology background of any type, you’ll immediately realize that this is a massive, expensive undertaking requiring vast computational resources. Not only that, but the rematching has to be done in tandem with new kits coming in, coordinated for all customers, and rolled out at once. Based on new matches and features, the user interface needed to be changed too, at the same time.

Sounds like a huge headache, right?

Why would a company ever decide to undertake that, especially when there is no revenue for doing so? The answer is to make functionality and accuracy better for their customers. Think of this as a new bedrock foundation for the future.

FamilyTreeDNA has made computational changes and implemented several features that require rematching:

  • Improved matching accuracy, in particular for people in highly endogamous populations. People in this category have thousands of matches that occur simply because they share multiple distant ancestors from within the same population. That combination of multiple common ancestors makes their current match relationships appear to be closer in time than they are. In order to change matching algorithms, FamilyTreeDNA had to rewrite their matching software and then run matching all over to enable everyone to receive new, updated match results.
  • FamilyTreeDNA has removed segments below 6 cM following sustained feedback from the genealogical community.
  • X matching has changed as well and no longer includes anyone as an X match below 6 cM.
  • Family Matching, meaning paternal, maternal and both “bucketing” uses triangulation behind the scenes. That code also had to be updated.
  • Older transfer kits used to receive only closer matches because imputation was not in place when the original transfer/upload took place. All older kits have been imputed now and matched with the entire database, which is part of why you may have more matches.
  • Relationship range calculations have changed, based on the removal of microsegments, new matching methodology and rematching results.
  • FamilyTreeDNA moved to hg37, known as Build 37 of the human genome. In layman’s terms, as scientists learn about our DNA, the human map of DNA changes and shifts slightly. The boundary lines change somewhat. Versions are standardized so all researchers can use the same base map or yardstick. In some cases, early genetic genealogy implementers are penalized because they will eventually have to rematch their entire database when they upgrade to a new build version, while vendors who came to the party later won’t have to bear that internal expense.

As you can see, almost every aspect of matching has changed, so everyone was rematched against the entire database. You’ll see new results. Some matches may be gone, especially distant matches or if you’re a member of an endogamous population.

You’ll likely have new matches due to older transfer kits being imputed to full compatibility. Your matches should be more accurate too, which makes everyone happy.

I understand a white paper is being written that will provide more information about the new matching algorithms.

Ok, now let’s check out the new Family Finder Matches page.

Family Finder Matches

FamilyTreeDNA didn’t just rearrange the furniture – there’s a LOT of new content.

First, a note. You’ll see “Family Finder” in some places, and “Autosomal DNA” in other places. That’s one and the same at FamilyTreeDNA. The Family Finder test is their autosomal test, named separately because they also have Y DNA and mitochondrial DNA tests.

When you click on Family Finder matches for the first time, you will assuredly notice one thing and will probably notice a second.

First, you’ll see a little tour that explains how to use the various new tools.

Secondly, you will probably see the “Generating Matches” notice for a few seconds to a few minutes while your match list is generated, especially if the site is busy because lots of people are signing on. I saw this message for maybe a minute or two before my match list filled.

This should be a slight delay, but with so many people signing in right now, my second kit took longer. If you receive a message that says you have no matches, just refresh your page. If you had matches before, you DO have matches now.

While working with the new interface this morning, I’ve found that refreshing the screen is the key to solving issues.

My kits that have a few thousand matches loaded Family Matching (bucketing) immediately, but this (Jewish) kit that has around 30,000 matches received this informational message instead. FamilyTreeDNA has removed the little spinning icon. If you mouse over the information, you’ll see the following message:

This isn’t a time estimate. Everyone receives the same message. The message didn’t even last long enough for me to get a screenshot on the first kit that received this message. The results completed within a minute or so. The Family Matching buckets will load as soon as the parental matching is ready.

These delays should only happen the first time, or if someone has a lot of matches that they haven’t yet viewed. Once you’ve signed in, your matches are cached, a technique that improves performance, so the loading should be speedy, or at least speedier, during the second and subsequent visits.

Of course, right now, all customers have an updated match list, so there’s something new for everyone.

Getting Help

Want to see that tutorial again?

Click on that little Help box in the upper right-hand corner. You can view the Tutorial, look at Quick References that explain what’s on this page, visit the Help Center or Submit Feedback.

Two Family Finder Matches Views – Detail and Table

The first thing you’ll notice is that there are two views – Detail View and Table View. The default is Detail View.

Take a minute to get used to the new page.

Detail View – Filter Matches by Match Type

I was pleased to see new filter buttons, located in several places on the page.

The Matches filter at left allows you to display only specific relationship levels, including X-Matches which can be important in narrowing matches to a specific subset of ancestors.

You can display only matches that fall within certain relationship ranges. Note the new “Remote Relative” that was previously called speculative.

Parental Matching and Filtering by Test Type or Trees

All of your matches are displayed by default, of course, but you can click on Paternal, Maternal or Both, like before to view only matches in those buckets. In order for the Family Matching bucketing feature to be enabled, you must attach known relatives’ DNA matches to their proper place in your tree.

Please note that I needed to refresh the page a couple of times to get my parental matches to load the first time. I refreshed a couple of times to be sure that all of my bucketed matches loaded. This should be a first-time loading blip.

There’s a new filter button to the right of the bucketing tabs.

You can now filter by who has trees and who has taken which kinds of tests.

You can apply multiple filters at the same time to further narrow your matches.

Important – Clearing Filters

It’s easy to forget you have a filter enabled. This section is important, in part because Clear Filter is difficult to find.

The clear filter button does NOT appear until you’ve selected a filter. However, after applying that filter, to clear it and RESET THE MATCHES to unfiltered, you need to click on the “Clear Filter” button which is located at the top of the filter selections, and then click “Apply” at the bottom of the menu. I looked for “clear filter” forever before finding it here.

You’re welcome😊

Enhanced Search

Thank goodness, the search functionality has been enhanced and simplified too. Full name search works, both here and on the Y DNA search page.

If you type in a surname without selecting any search filters, you’ll receive a list of anyone with that word in their name, or in their list of ancestral surnames. This does NOT include surnames in their tree if they have not added those surnames to their list of ancestral surnames.

Notice that your number of total matches and bucketed people will change based on the results of this search and any filters you have applied.

I entered Estes in the search box, with no filters. You can see that I have a total of 46 matches that contain Estes in one way or another, and how they are bucketed.

Estes is my birth surname. I noticed that three people with Estes in their information are bucketed maternally. This is the perfect example of why you can’t assume a genetic relationship based on only a surname. Those three people’s DNA matches me on my mother’s side. And yes, I confirmed that they matched my mother too on that same segment or segments.

Search Filters

You can also filter by haplogroup. This is very specific. If you select mitochondrial haplogroup J, you will only receive Family Finder matches that have haplogroup J, NOT J1 or J1c or J plus anything.

If you’re looking for your own haplogroup, you’ll need to type your full haplogroup in the search box and select mtDNA Haplogroup in the search filter dropdown.

Resetting Search Results

To dismiss search results, click on the little X. It’s easy to forget that you have initiated a search, so I need to remember to dismiss searches after I’m finished with each one.

Export Matches

The “Export CSV” button either downloads your entire match list, or the list of filtered matches currently selected. This is not your segment information, but a list of matches and related information such as which side they are bucketed on, if any, notes you’ve made, and more.

Your segment information is available for download on the chromosome browser.

Sort By

The Sort By button facilitates sorting your matches versus filtering your matches. Filters ONLY display the items requested, while sorts display all of the items requested, sorting them in a particular manner.

You can sort in any number of ways. The default is Relationship Range followed by Shared DNA.

Your Matches – Detail View

A lot has changed, but after you get used to the new interface, it makes more sense and there are a lot more options available which means increased flexibility. Remember, you can click to enlarge any of these images.

To begin with, you can see the haplogroups of your matches if they have taken a Y or mitochondrial DNA test. If you match someone, you’ll see a little check in the haplogroup box. I’m not clear whether this means you’re a haplogroup match or that person is on your match list.

To select people to compare in the chromosome browser, you simply check the little square box to the left of their photo and the chromosome browser box pops up at the bottom of the page. We’ll review the chromosome browser in a minute.

The new Relationship Range prediction is displayed, based on new calculations with segments below 6 cM removed. The linked relationship is displayed below the range.

A linked relationship occurs when you link that person to their proper place in your tree. If you have no linked relationship, you’ll see a link to “assign relationship” which takes you to your tree to link this person if you know how you are related.

The segments below 6 cM are gone from the Shared DNA total and X matches are only shown if they are 6 cM or above.

In Common With and Not In Common With

In Common With and Not In Common With is the little two-person icon at the right.

Just click on the little person icon, then select “In Common With” to view your shared matches between you, that match, and other people. The person you are viewing matches in common with is highlighted at the top of the page, with your common matches below.

You can stack filters now. In this example, I selected my cousin, Don, to see our common matches. I added the search filter of the surname Ferverda, my mother’s maiden name. She is deceased and I manage her kit. You can see that my cousin Don and I have 5 total common matches – four maternal and one both, meaning one person matches me on both my maternal and paternal lines.

It’s great news that now Cousin Don pops up in the chromosome browser box at the bottom, enabling easy confusion-free chromosome segment comparisons directly from the In Common With match page. I love this!!!.

All I have to do now is click on other people and then on Compare Relationship which pushes these matches through to the chromosome browser. This is SOOOO convenient.

You’ll see a new tree icon at right on each match. A dark tree means there’s content and a light tree means this person does not have a tree. Remember, you can filter by trees with content using the filter button beside “Both”.

Your notes are shown at far right. Any person with a note is dark grey and no note is white.

If you’re looking for the email contact information, click on your match’s name to view their placard which also includes more detailed ancestral surname information.

Family Finder – Table View

The table view is very similar to the Detail View. The layout is a bit different with more matches visible in the same space.

This view has lots of tooltips on the column heading bar! Tooltips are great for everyone, but especially for people just beginning to find their way in the genetic genealogy world.

I’ll have to experiment a bit to figure out which view I prefer. I’d like to be able to set my own default for whichever view I want as my default. In fact, I think I’ll submit that in the “Submit Feedback” link. For every suggestion, I’m going to find something really positive to say. This was an immense overhaul.

Chromosome Browser

Let’s look at the chromosome Browser.

You can arrive at the Chromosome Browser by selecting people on your match page, or by selecting the Chromosome Browser under the Results and Tools link.

Everything is pretty much the same on the chromosome browser, except the default view is now 6 cM and the smaller segments are gone. You can also choose to view only segments above 10 cM.

If you have people selected in the chromosome browser and click on Download Segments in the upper right-hand corner, it downloads the segments of only the people currently selected.

You can “Clear All” and then click on Download All Segments which downloads your entire segment file. To download all segments, you need to have no people selected for comparison.

The contents of this file are greatly reduced as it now contains only the segments 6 cM and above.

Family Tree

No, the family tree has not changed, and yes, it needs to, desperately. Trust me, the management team is aware and I suspect one of the improvements, hopefully sooner than later, will be an improved tree experience.

Y DNA

The Y DNA page has received an update too, adding both a Detail View and a Table View with the same basic functionality as the Family Finder matching above. If you are reading this article for Y DNA only, please read the Family Finder section to understand the new layout and features.

Like previously, the match comparison begins at the 111 marker level.

However, there’s a BIG difference. If there are no matches at this level, YOU NEED TO CLICK THE NEXT TAB. You can easily see that this person has matches at the 67 level and below, but the system no longer “counts down” through the various levels until it either finds a level with a match or reaches 12 markers.

If you’re used to the old interface, it’s easy to think you’re at the final destination of 12 markers with no matches when you’re still at 111.

Y DNA Detail View

The Y-DNA Detail and Table views features are the same as Family Finder and are described in that section.

The new format is quite different. One improvement is that the Paternal Country of Origin is now displayed, along with a flag. How cool is that!

The Paternal Earliest Known Ancestor and Match Date are at far right. Note that match dates have been reset to the rerun date. At this point, FamilyTreeDNA is evaluating the possibility of restoring the original match date. Regardless, you’ll be able to filter for match dates when new matches arrive.

Please check to be sure you have your Country of Origin, Earliest Known Ancestor, and mapped location completed and up to date.

Earliest Known Ancestor

If you haven’t completed your Earliest Known Ancestor (EKA) information, now’s the perfect time. It’s easy, so let’s do it before you forget.

Click on the Account Settings gear beneath your name in the right-hand upper corner. Click on Genealogy, then on Earliest Known Ancestors and complete the information in the red boxes.

  • Direct paternal line means your father’s father’s father’s line – as far up through all fathers as you can reach. This is your Y DNA lineage, but females should complete this information on general principles.
  • Direct maternal line means your mother’s mother’s mother’s line – as far up through all mothers that you can reach. This is your mitochondrial DNA lineage, so relevant for both males and females.

Completing all of the information, including the location, will help you and your matches as well when using the Matches Map.

Be sure to click Save when you’re finished.

Y DNA Filters

Y DNA has more filter options than autosomal.

The Y DNA filter, located to the right of the 12 Markers tab allows testers to filter by:

  • Genetic distance, meaning how many mutations difference between you and your matches
  • Groups meaning group projects that the tester has joined
  • Tree status
  • Match date
  • Level of test taken

If none of your matches have taken the 111 marker test or you don’t match anyone at that level, that test won’t show up on your list.

Y DNA Table View

As with Family Finder, the Table View is more condensed and additional features are available on the right side of each match. For details, please review the Family Finder section.

If you’re looking for the old Y DNA TiP report, it’s now at the far right of each match.

The actual calculator hasn’t changed yet. I know people were hoping for the new Y DNA aging in this release, but that’s yet to follow.

Other Pages

Other pages like the Big Y and Mitochondrial DNA did not receive new features or functionality in this release, but do sport new user-friendly tooltips.

I lost track, but I counted over 100 tooltips added across the platform, and this is just the beginning.

There are probably more new features and functionality that I haven’t stumbled across just yet.

And yes, we are going to find a few bugs. That’s inevitable with something this large. Please report anything you find to FamilyTreeDNA.

Oh wait – I almost forgot…

New Videos

I understand that there are in the ballpark of 50 new videos that are being added to the new Help Center, either today or very shortly.

When I find out more, I’ll write an article about what videos are available and where to find them. People learn in various ways. Videos are often requested and will be a popular addition. I considered making videos, but that’s almost impossible for anyone besides the vendor because the names on screens either need to be “fake” or the screen needs to be blurred.

So hurray – very glad to hear these are imminent!

Stay Tuned

Stay tuned for new developments. As Lior said, FamilyTreeDNA is investing heavily in genetic genealogy and there’s more to come.

My Mom used to say that the “proof is in the pudding.” I’d say the myDNA/FamilyTreeDNA leadership team has passed this initial test with flying colors.

Of course, there’s more to do, but I’m definitely grateful for this lovely pudding. Thank you – thank you!

I can’t wait to get started and see what new gems await.

Take a Look!

Sign in and take a look for yourself.

Do you have more matches?

Are your matches more accurate?

How about predicted relationships?

How has this new release affected you?

What do you like the best?

A Triangulation Checklist Born From the Question; “Why NOT Use Close Relatives for Triangulation?”

One of my readers asked why we don’t use close relatives for triangulation.

This is a great question because not using close relatives for triangulation seems counter-intuitive.

I used to ask my kids and eventually my students and customers if they wanted the quick short answer or the longer educational answer.

The short answer is “because close relatives are too close to reliably form the third leg of the triangle.” Since you share so much DNA with close relatives, someone matching you who is identical by chance can also match them for exactly the same reason.

If you trust me and you’re good with that answer, wonderful. But I hope you’ll keep reading because there’s so much to consider, not to mention a few gotchas. I’ll share my methodology, techniques, and workarounds.

We’ll also discuss absolutely wonderful ways to utilize close relatives in the genetic genealogical process – just not for triangulation.

At the end of this article, I’ve provided a working triangulation checklist for you to use when evaluating your matches.

Let’s go!

The Step-by-Step Educational Answer😊

Some people see “evidence” they believe conflicts with the concept that you should not use close relatives for triangulation. I understand that, because I’ve gone down that rathole too, so I’m providing the “educational answer” that explains exactly WHY you should not use close relatives for triangulation – and what you should do.

Of course, we need to answer the question, “Who actually are close relatives?”

I’ll explain the best ways to best utilize close relatives in genetic genealogy, and why some matches are deceptive.

You’ll need to understand the underpinnings of DNA inheritance and also of how the different vendors handle DNA matching behind the scenes.

The purpose of autosomal DNA triangulation is to confirm that a segment is passed down from a particular ancestor to you and a specific set of your matches.

Triangulation, of course, implies 3, so at least three people must all match each other on a reasonably sized portion of the same DNA segment for triangulation to occur.

Matching just one person only provides you with one path to that common ancestor. It’s possible that you match that person due to a different ancestor that you aren’t aware of, or due to chance recombination of DNA.

It’s possible that your or your match inherited part of that DNA from your maternal side and part from your paternal side, meaning that you are matching that other person’s DNA by chance.

I wrote about identical by descent (IBD), which is an accurate genealogically meaningful match, and identical by chance (IBC) which is a false match, in the article Concepts – Identical by…Descent, State, Population and Chance.

I really want you to understand why close relatives really shouldn’t be used for triangulation, and HOW close relative matches should be used, so we’re going to discuss all of the factors that affect and influence this topic – both the obvious and little-understood.

  • Legitimate Matches
  • Inheritance and Triangulation
  • Parental Cross-Matching
  • Parental Phasing
  • Automatic Phasing at FamilyTreeDNA
  • Parental Phasing Caveats
  • Pedigree Collapse
  • Endogamy
  • How Many Identical-by-Chance Matches Will I Have?

  • Siblings
  • How False Positives Work and How to Avoid Them
  • Distant Cousins Are Best for Triangulation & Here’s Why
  • Where Are We? A Triangulation Checklist for You!
  • The Bottom Line

Don’t worry, these sections are logical and concise. I considered making this into multiple articles, but I really want it in one place for you. I’ve created lots of graphics with examples to help out.

Let’s start by dispelling a myth.

DNA Doesn’t Skip Generations!

Recently, someone emailed to let me know that they had “stopped listening to me” in a presentation when I said that if a match did not also match one of your parents, it was a false match. That person informed me that they had worked on their tree for three years at Ancestry and they have “proof” of DNA skipping generations.

Nope, sorry. That really doesn’t happen, but there are circumstances when a person who doesn’t understand either how DNA works, or how the vendor they are using presents DNA results could misunderstand or misinterpret the results.

You can watch my presentation, RootsTech session, DNA Triangulation: What, Why and How, for free here. I’m thrilled that this session is now being used in courses at two different universities.

DNA really doesn’t skip generations. You CANNOT inherit DNA that your parents didn’t have.

Full stop.

Your children cannot inherit DNA from you that you don’t carry. If you don’t have that DNA, your children and their descendants can’t have it either, at least not from you. They of course do inherit DNA from their other parent.

I think historically, the “skipping generations” commentary was connected to traits. For example, Susie has dimples (or whatever) and so did her maternal grandmother, but her mother did not, so Susie’s dimples were said to have “skipped a generation.” Of course, we don’t know anything about Susie’s other grandparents, if Susie’s parents share ancestors, recessive/dominant genes or even how many genetic locations are involved with the inheritance of “dimples,” but I digress.

DNA skipping generations is a fallacy.

You cannot legitimately match someone that your parent does not, at least not through that parent’s side of the tree.

But here’s the caveat. You can’t match someone one of your parents doesn’t with the rare exception of:

  • Relatively recent pedigree collapse that occurs when you have the same ancestors on both sides of your tree, meaning your parents are related, AND
  • The process of recombination just happened to split and recombine a segment of DNA in segments too small for your match to match your parents individually, but large enough when recombined to match you.

We’ll talk about that more in a minute.

However, the person working with Ancestry trees can’t make this determination because Ancestry doesn’t provide segment information. Ancestry also handles DNA differently than other vendors, which we’ll also discuss shortly.

We’ll review all of this, but let’s start at the beginning and explain how to determine if our matches are legitimate, or not.

Legitimate Matches

Legitimate matches occur when the DNA of your ancestor is passed from that ancestor to their descendants, and eventually to you and a match in an unbroken pathway.

Unbroken means that every ancestor between you and that ancestor carried and then passed on the segment of the ancestor’s DNA that you carry today. The same is true for your match who carries the same segment of DNA from your common ancestor.

False positive matches occur when the DNA of a male and female combine randomly to look like a legitimate match to someone else.

Thankfully, there are ways to tell the difference.

Inheritance and Triangulation

Remember, you inherit two copies of each of your chromosomes 1-22, one copy from your mother and one from your father. You inherit half of the DNA that each parent carries, but it’s mixed together in you so the labs can’t readily tell which nucleotide, A, C, T, or G you received from which parent. I’m showing your maternal and paternal DNA in the graphic below, stacked neatly together in a column – but in reality, it could be AC in one position and CA in the next.

For matching all that matters is the nucleotide that matches your match is present in one of those two locations. In this case, A for your mother’s side and C for your father’s side. If you’re interested, you can read more about that in the article, Hit a Genealogy Home Run Using Your Double-Sided Two-Faced Chromosomes While Avoiding Imposters.

You can see in this example that you inherited all As from your Mom and all Cs from your Dad.

  • A legitimate maternal match would match you on all As on this particular example segment.
  • A legitimate paternal match would match you on all Cs on this particular segment.
  • A false positive match will match you on some random combination of As and Cs that make it look like they match you legitimately, but they don’t.
  • A false positive match will NOT match either your mother or your father.

To be very clear, technically a false positive match DOES match your DNA – but they don’t match your DNA because you share a common ancestor with your match. They match you because random recombination on their side causes you to match each other by chance.

In other words, if part of your DNA came from your Mom’s side and part from your Dad’s but it randomly fell in the correct positional order, you’d still match someone whose DNA was from only their mother or father’s side. That’s exactly the situation shown above and below.

Looking at our example again, it’s evident that your identical by chance (IBC) match’s A locations (1, 3, 5, 7 & 9) will match your Mom. C locations (2, 4, 6 8, & 10) will match your Dad, but the nonmatching segments interleaved in-between that match alternating parents will prevent your match from matching either of your parents. In other words, out of 10 contiguous locations in our example, your IBC match has 5 As alternated with 5 Cs, so they won’t match either of your parents who have 10 As or 10 Cs in a row.

This recombination effect can work in either direction. Either or both matching people’s DNA could be randomly mixed causing them to match each other, but not their parents.

Regardless of whose DNA is zigzagging back and forth between maternal and paternal, the match is not genealogical and does not confirm a common ancestor.

This is exactly why triangulation works and is crucial.

If you legitimately match a third person, shown below, on your maternal side, they will match you, your first legitimate maternal match, and your Mom because they carry all As. But they WON’T match the person who is matching you because they are identical by chance, shown in grey below.

The only person your identical by chance match matches in this group is you because they match you because of the chance recombination of parental DNA.

That third person WILL also match all other legitimate maternal matches on this segment.

In the graphic above, we see that while the grey identical by chance person matches you because of the random combination of As from your mother and Cs from your father, your legitimate maternal matches won’t match your identical by chance match.

This is the first step in identifying false matches.

Parental Cross-Matching

Removing the identical by chance match, and adding in the parents of your legitimate maternal match, we see that your maternal match, above, matches you because you both have all As inherited from one parent, not from a combination of both parents.

We know that because we can see the DNA of both parents of both matches in this example.

The ideal situation occurs when two people match and they have both had their parents tested. We need to see if each person matches the other person’s parents.

We can see that you do NOT match your match’s father and your match does NOT match your father.

You do match your match’s mother and your match does match your mother. I refer to this as Parental Cross-matching.

Your legitimate maternal matches will also match each other and your mother if she is available for testing.

All the people in yellow match each other, while the two parents in gray do not match any of your matches. An entire group of legitimate maternal matches on this segment, no matter how many, will all match each other.

If another person matches you and the other yellow people, you’ll still need to see if you match their parents, because if not, that means they are matching you on all As because their two parents DNA combined just happened, by chance, to contribute an A in all of those positions.

In this last example, your new match, in green, matches you, your legitimate match and both of your mothers, BUT, none of the four yellow people match either of the new match’s parents. You can see that the new green match inherited their As from the DNA of their mother and father both, randomly zigzagging back and forth.

The four yellow matches phase parentally as we just proved with cross matching to parents. The new match at first glance appears to be a legitimate match because they match all of the yellow people – but they aren’t because the yellow people don’t match the green person’s parents.

To tell the difference between legitimate matches and identical by chance matches, you need two things, in order.

  • Parental matching known as parental phasing along with parental cross-matching, if possible, AND
  • Legitimate identical by descent (IBD) triangulated matches

If you have the ability to perform parental matching, called phasing, that’s the easiest first step in eliminating identical by chance matches. However, few match pairs will have parents for everyone. You can use triangulation without parental phasing if parents aren’t available.

Let’s talk about both, including when and how close relatives can and cannot be used.

Parental Phasing

The technique of confirming your match to be legitimate by your match also matching one of your parents is called parental phasing.

If we have the parents of both people in a match pair available for matching, we can easily tell if the match does NOT match either parent. That’s Parental Cross Matching. If either match does NOT match one of the other person’s parents, the match is identical by chance, also known as a false positive.

See how easy that was!

If you, for example, is the only person in your match pair to have parents available, then you can parentally phase the match on your side if your match matches your parents. However, because your match’s parents are unavailable, your match to them cannon tbe verified as legitimate on their side. So you are not phased to their parents.

If you only have one of your parents available for matching, and your match does not match that parent, you CANNOT presume that because your match does NOT match that parent, the match is a legitimate match for the other, missing, parent.

There are four possible match conditions:

  • Maternal match
  • Paternal match
  • Matches neither parent which means the match is identical by chance meaning a false positive
  • Matches both parents in the case of pedigree collapse or endogamy

If two matching people do match one parent of both matches (parental cross-matching), then the match is legitimate. In other words, if we match, I need to match one of your parents and you need to match one of mine.

It’s important to compare your matches’ DNA to generationally older direct family members such as parents or grandparents, if that’s possible. If your grandparents are available, it’s possible to phase your matches back another generation.

Automatic Phasing at FamilyTreeDNA

FamilyTreeDNA automatically phases your matches to your parents if you test that parent, create or upload a GEDCOM file, and link your test and theirs to your tree in the proper places.

FamilyTreeDNA‘s Family Matching assigns or “buckets” your matches maternally and paternally. Matches are assigned as maternal or paternal matches if one or both parents have tested.

Additionally, FamilyTreeDNA uses triangulated matches from other linked relatives within your tree even if your parents have not tested. If you don’t have your parents, the more people you identify and link to your tree in the proper place, the more people will be assigned to maternal and paternal buckets. FamilyTreeDNA is the only vendor that does this. I wrote about this process in the article, Triangulation in Action at Family Tree DNA.

Parental Phasing Caveats

There are very rare instances where parental phasing may be technically accurate, but not genealogically relevant. By this, I mean that a parent may actually match one of your matches due to endogamy or a population level match, even if it’s considered a false positive because it’s not relevant in a genealogical timeframe.

Conversely, a parent may not match when the segment is actually legitimate, but it’s quite rare and only when pedigree collapse has occurred in a very specific set of circumstances where both parents share a common ancestor.

Let’s take a look at that.

Pedigree Collapse

It’s not terribly uncommon in the not-too-distant past to find first cousins marrying each other, especially in rather closely-knit religious communities. I encounter this in Brethren, Mennonite and Amish families often where the community was small and out-marrying was frowned upon and highly discouraged. These families and sometimes entire church congregations migrated cross-country together for generations.

When pedigree collapse is present, meaning the mother and father share a common ancestor not far in the past, it is possible to inherit half of one segment from Mom and the other half from Dad where those halves originated with the same ancestral couple.

For example, let’s say the matching segment between you and your match is 12 cM in length, shown below. You inherited the blue segment from your Dad and the neighboring peach segment from Mom – shown just below the segment numbers. You received 6 cM from both parents.

Another person’s DNA does match you, shown in the bottom row, but they are not shown on the DNA match list of either of your parents. That’s because the DNA segments of the parents just happened to recombine in 6 cM pieces, respectively, which is below the 7 cM matching threshold of the vendor in this example.

If the person matched you at 12 cM where you inherited 8 cM from one parent and 4 from the other, that person would show on one parent’s match list, but not the other. They would not be on the parent’s match list who contributed only 4 cM simply because the DNA divided and recombined in that manner. They would match you on a longer segment than they match your parent at 8 cM which you might notice as “odd.”

Let’s look at another example.

click to enlarge image

If the matching segment is 20 cM, the person will match you and both of your parents on different pieces of the same segment, given that both segments are above 7 cM. In this case, your match who matches you at 20 cM will match each of your parents at 10 cM.

You would be able to tell that the end location of Dad’s segment is the same as the start location of Mom’s segment.

This is NOT common and is NOT the “go to” answer when you think someone “should” match your parent and does not. It may be worth considering in known pedigree collapse situations.

You can see why someone observing this phenomenon could “presume” that DNA skipped a generation because the person matches you on segments where they don’t match your parent. But DNA didn’t skip anything at all. This circumstance was caused by a combination of pedigree collapse, random division of DNA, then random recombination in the same location where that same DNA segment was divided earlier. Clearly, this sequence of events is not something that happens often.

If you’ve uploaded your DNA to GEDmatch, you can select the “Are your parents related?” function which scans your DNA file for runs of homozygosity (ROH) where your DNA is exactly the same in both parental locations for a significant distance. This suggests that because you inherited the exact same sequence from both parents, that your parents share an ancestor.

If your parents didn’t inherit the same segment of DNA from both parents, or the segment is too short, then they won’t show as “being related,” even if they do share a common ancestor.

Now, let’s look at the opposite situation. Parental phasing and ROH sometimes do occur when common ancestors are far back in time and the match is not genealogically relevant.

Endogamy

I often see non-genealogical matching occur when dealing with endogamy. Endogamy occurs when an entire population has been isolated genetically for a long time. In this circumstance, a substantial part of the population shares common DNA segments because there were few original population founders. Much of the present-day population carries that same DNA. Many people within that population would match on that segment. Think about the Jewish community and indigenous Americans.

Consider our original example, but this time where much of the endogamous population carries all As in these positions because one of the original founders carried that nucleotide sequence. Many people would match lots of other people regardless of whether they are a close relative or share a distant ancestor.

People with endogamous lines do share relatives, but that matching DNA segment originated in ancestors much further back in time. When dealing with endogamy, I use parental phasing as a first step, if possible, then focus on larger matches, generally 20 cM or greater. Smaller matches either aren’t relevant or you often can’t tell if/how they are.

At FamilyTreeDNA, people with endogamy will find many people bucketed on the “Both” tab meaning they triangulate with people linked on both sides of the tester’s tree.

An example of a Jewish person’s bucketed matches based on triangulation with relatives linked in their tree is shown above.

Your siblings, their children, and your children will be related on both your mother’s and father’s sides, but other people typically won’t be unless you have experienced either pedigree collapse where you are related both maternally and paternally through the same ancestors or you descend from an endogamous population.

How Many Identical-by-Chance Matches Will I Have?

If you have both parents available to test, and you’re not dealing with either pedigree collapse or endogamy, you’ll likely find that about 15-20% of your matches don’t match your parents on the same segment and are identical by chance.

With endogamy, you’ll have MANY more matches on your endogamous lines and you’ll have some irrelevant matches, often referred to as “false positive” matches even though they technically aren’t, even using parental phasing.

Your Parents Have DNA That You Don’t

Sometimes people are confused when reviewing their matches and their parent’s match to the same person, especially when they match someone and their parent matches them on a different or an additional segment.

If you match someone on a specific segment and your parents do not, that’s a false positive FOR THAT SEGMENT. Every segment has its own individual history and should be evaluated individually. You can match someone on two segments, one from each parent. Or three segments, one from each parent and one that’s identical by chance. Don’t assume.

Often, your match will match both you and your parent on the same segment – which is a legitimate parentally phased match.

But what if your match matches your parent on a different segment where they don’t match you? That’s a false positive match for you.

Keep in mind that it is possible for one of your matches to match your parent on a separate or an additional segment that IS legitimate. You simply didn’t inherit that particular segment from your parent.

That’s NOT the same situation as someone matching you that does NOT match one of your parents on the same segment – which is an identical by chance or false match.

Your parent having a match that does not match you is the reverse situation.

I have several situations where I match someone on one segment, and they match my parent on the same segment. Additionally, that person matches my parent on another segment that I did NOT inherit from that parent. That’s perfectly normal.

Remember, you only inherit half of your parent’s DNA, so you literally did NOT inherit the other half of their DNA. Your mother, for example, should have twice as many matches as you on her side because roughly half of her matches won’t match you.

That’s exactly why testing your parents and close family members is so critical. Their matches are as valid and relevant to your genealogy as your own. The same is true for other relatives, such as aunts and uncles with whom you share ALL of the same ancestors.

You need to work with your family member’s matches that you don’t share.

No DNA Match Doesn’t Mean You’re Not Related

Some people think that not matching someone on a DNA test is equivalent to saying they aren’t related. Not sharing DNA doesn’t mean you’re not related.

People are often disappointed when they don’t match someone they think they should and interpret that to mean that the testing company is telling them they “aren’t related.” They are upset and take issue with this characterization. But that’s not what it means.

Let’s analyze this a bit further.

First, not sharing DNA with a second cousin once removed (2C1R) or more distant does NOT mean you’re NOT related to that person. It simply means you don’t share any measurable DNA ABOVE THE VENDOR THRESHOLD.

All known second cousins match, but about 10% of third cousins don’t match, and so forth on up the line with each generation further back in time having fewer cousins that match each other.

If you have tested close relatives, check to see if that cousin matches your relatives.

Second, it’s possible to match through the “other” or unexpected parent. I certainly didn’t think this would be the case in my family, because my father is from Appalachia and my mother’s family is primarily from the Netherlands, Germany, Canada, and New England. But I was wrong.

All it took was one German son that settled in Appalachia, and voila, a match through my mother that I surely thought should have been through my father’s side. I have my mother’s DNA and sure enough, my match that I thought should be on my father’s side matches Mom on the same segment where they match me, along with several triangulated matches. Further research confirmed why.

I’ve also encountered situations where I legitimately match someone on both my mother’s and father’s side, on different segments.

Third, imputation can be important for people who don’t match and think they should. Imputation can also cause matching segment length to be overreported.

Ok, so what’s imputation and why do I care?

Imputation

Every DNA vendor today has to use some type of imputation.

Let me explain, in general, what imputation is and why vendors use it.

Over the years, DNA processing vendors who sell DNA chips to testing companies have changed their DNA chips pretty substantially. While genealogical autosomal tests test about 700,000 DNA locations, plus or minus, those locations have changed over time. Today, some of these chips only have 100,000 or so chip locations in common with chips either currently or previously utilized by other vendors.

The vendors who do NOT accept uploads, such as 23andMe or Ancestry, have to develop methods to make their newest customers on their DNA processing vendor’s latest chip compatible with their first customer who was tested on their oldest chip – and all iterations in-between.

Vendors who do accept transfers/uploads from other vendors have to equalize any number of vendors’ chips when their customers upload those files.

Imputation is the scientific way to achieve this cross-platform functionality and has been widely used in the industry since 2017.

Imputation, in essence, fills in the blanks between tested locations with the “most likely” DNA found in the human population based on what’s surrounding the blank location.

Think of the word C_T. There are a limited number of letters and words that are candidates for C_T. If you use the word in a sentence, your odds of accuracy increase dramatically. Think of a genetic string of nucleotides as a sentence.

Imputation can be incorrect and can cause both false positive and false negative matches.

For the most part, imputation does not affect close family matches as much as more distant matches. In other words, imputation is NOT going to cause close family members not to match.

Imputation may cause more distant family members not to match, or to have a false positive match when imputation is incorrect.

Imputation is actually MUCH less problematic than I initially expected.

The most likely effect of imputation is to cause a match to be just above or below the vendor threshold.

How can we minimize the effects of imputation?

  • Generally, the best result will be achieved if both people test at the same vendor where their DNA is processed on the same chip and less imputation is required.
  • Upload the results of both people to both MyHeritage and FamilyTreeDNA. If your match results are generally consistent at those vendors, imputation is not a factor.
  • GEDmatch does not use imputation but attempts to overcome files with low overlapping regions by allowing larger mismatch areas. I find their matches to be less accurate than at the various vendors.

Additionally, Ancestry has a few complicating factors.

Ancestry Issues

AncestryDNA is different in three ways.

  • Ancestry doesn’t provide segment information so it’s impossible to triangulate or identify the segment or chromosome where people match. There is no chromosome browser or triangulation tool.
  • Ancestry down-weights and removes some segments in areas where they feel that people are “too matchy.” You can read Ancestry’s white papers here and here.

These “personal pileup regions,” as they are known, can be important genealogically. In my case, these are my mother’s Acadian ancestors. Yes, this is an endogamous population and also suffers from pedigree collapse, but since this is only one of my mother’s great-grandparents, this match information is useful and should not be removed.

  • Ancestry doesn’t show matches in common if the shared segments are less than 20cM. Therefore, you may not see someone on a shared match list with a relative when they actually are a shared match.

If two people both match a third person on less than a 20 cM segment at Ancestry, the third person won’t appear on the other person’s shared match list. So, if I match John Doe on 19 cM of DNA, and I looked at the shared matches with my Dad, John Doe does NOT appear on the shared match list of me and my Dad – even though he is a match to both of us at 19 cM.

The only way to determine if John Doe is a shared match is to check my Dad’s and my match list individually, which means Dad and I will need to individually search for John Doe.

Caveat here – Ancestry’s search sometimes does not work correctly.

Might someone who doesn’t understand that the shared match list doesn’t show everyone who shares DNA with both people presume that the ancestral DNA of that ancestor “skipped a generation” because John Doe matches me with a known ancestor, and not Dad on our shared match list? I mean, wouldn’t you think that a shared match would be shown on a tab labeled “Shared Matches,” especially since there is no disclaimer?

Yes, people can be forgiven for believing that somehow DNA “skipped” a generation in this circumstance, especially if they are relatively inexperienced and they don’t understand Ancestry’s anomalies or know that they need to or how to search for matches individually.

Even if John Doe does match me and Dad both, we still need to confirm that it’s on the same segment AND it’s a legitimate match, not IBC. You can’t perform either of these functions at Ancestry, but you can elsewhere.

Ancestry WorkArounds

To obtain this functionality, people can upload their DNA files for free to both FamilyTreeDNA and MyHeritage, companies that do provide full shared DNA reporting (in common with) lists of ALL matches and do provide segment information with chromosome browsers. Furthermore, both provide triangulation in different ways.

Matching is free, but an inexpensive unlock is required at both vendors to access advanced tools such as Family Matching (bucketing) and triangulation at Family Tree DNA and phasing/triangulation at MyHeritage.

I wrote about Triangulation in Action at FamilyTreeDNA, here.

MyHeritage actually brackets triangulated segments for customers on their chromosome browser, including parents, so you get triangulation and parental phasing at the same time if you and your parent have both tested or uploaded your DNA file to MyHeritage. You can upload, for free, here.

In this example, my mother is matching to me in red on the entire length of chromosome 18, of course, and three other maternal cousins triangulate with me and mother inside the bracketed portion of chromosome 18. Please note that if any one of the people included in the chromosome browser comparison do not triangulate, no bracket is drawn around any others who do triangulate. It’s all or nothing. I remove people one by one to see if people triangulate – or build one by one with my mother included.

I wrote about Triangulation in Action at MyHeritage, here.

People can also upload to GEDmatch, a third-party site. While GEDmatch is less reliable for matching, you can adjust your search thresholds which you cannot do at other vendors. I don’t recommend routinely working below 7 cM. I occasionally use GEDmatch to see if a pedigree collapse segment has recombined below another vendor’s segment matching threshold.

Do NOT check the box to prevent hard breaks when selecting the One-to-One comparison. Checking that box allows GEDmatch to combine smaller matching segments into mega-segments for matching.

I wrote about Triangulation in Action at GEDmatch, here.

Transferring/Uploading Your DNA 

If you want to transfer your DNA to one of these vendors, you must download the DNA file from one vendor and upload it to another. That process does NOT remove your DNA file from the vendor where you tested, unless you select that option entirely separately.

I wrote full step-by-step transfer/upload instructions for each vendor, here.

Testing Close Relatives Is VERY Useful – Just Not for Triangulation

Of course, your best bet if you don’t have your parents available to test is to test as many of your grandparents, great-aunts/uncles, aunts, and uncles as possible. Test your siblings as well, because they will have inherited some of the same and some different segments of DNA from your parents – which means they carry different pieces of your ancestors’ DNA.

Just because close relatives don’t make good triangulation candidates doesn’t mean they aren’t valuable. Close relatives are golden because when they DO share a match with you, you know where to start looking for a common ancestor, even if your relative matches that person on a different segment than you do.

Close relatives are also important because they will share pieces of your common ancestor’s DNA that you don’t. Their matches can unlock the answers to your genealogy questions.

Ok, back to triangulation.

Triangulated Matches

A triangulated match is, of course, when three people all descended from a common ancestor and match each other on the same segment of DNA.

That means all three people’s DNA matches each other on that same segment, confirming that the match is not by chance, and that segment did descend from a common ancestor or ancestral couple.

But, is this always true? You’re going to hate this answer…

“It depends.”

You knew that was coming, didn’t you! 😊

It depends on the circumstances and relationships of the three people involved.

  • One of those three people can match the other two by chance, not by descent, especially if two of those people are close relatives to each other.
  • Identical by chance means that one of you didn’t inherit that DNA from one single parent. That zigzag phenomenon.
  • Furthermore, triangulated DNA is only valid as far back as the closest common ancestor of any two of the three people.

Let’s explore some examples.

Building Triangulation Evidence – Ingredients and a Recipe

The strongest case of triangulation is when:

  • You and at least two additional cousins match on the same segment AND
  • Descend through different children of the common ancestral couple

Let’s look at a valid triangulated match.

In this first example, the magenta segment of DNA is at least partially shared by four of the six cousins and triangulates to their common great-grandfather. Let’s say that these cousins then match with two other people descended from different children of their great-great-great-grandparents on this same segment. Then the entire triangulation group will have confirmed that segment’s origin and push the descent of that segment back another two generations.

These people all coalesce into one line with their common great-grandparents.

I’m only showing 3 generations in this triangulated match, but the concept is the same no matter how many generations you reach back in time. Although, over time, segments inherited from any specific ancestor become smaller and smaller until they are no longer passed to the next generation.

In this pedigree chart, we’re only tracking the magenta DNA which is passed generation to generation in descendants.

Eventually, of course, those segments become smaller and indistinguishable as they either aren’t passed on at all or drop below vendor matching thresholds.

This chart shows the average amount of DNA you would carry from each generational ancestor. You inherit half of each parent’s DNA, but back further than that, you don’t receive exactly half of any ancestor’s DNA in any generation. Larger segments are generally cut in two and passed on partially, but smaller segments are often either passed on whole or not at all.

On average, you’ll carry 7 cM of your eight-times-great-grandparents. In reality, you may carry more or you may not carry any – and you are unlikely to carry the same segment as any random other descendants but we know it happens and you’ll find them if enough (or the right) descendants test.

Putting this another way, if you divide all of your approximate 7000 cM of DNA into 7 cM segments of equal length – you’ll have 1000 7 cM segments. So will every other descendant of your eight-times-great-grandparent. You can see how small the chances are of you both inheriting that same exact 7 cM segment through ten inheritance/transmission events, each. Yet it does happen.

I have several triangulated matches with descendants of Charles Dodson and his wife, Anne through multiple of their 9 (or so) children, ten generations back in my tree. Those triangulated matches range from 7-38 cM. It’s possible that those three largest matches at 38 cM could be related through multiple ancestors because we all have holes in our trees – including Anne’s surname.

Click to enlarge image

It helps immensely that Charles Dodson had several children who were quite prolific as well.

Of course, the further back in time, the more “proof” is necessary to eliminate other unknown common ancestors. This is exactly why matching through different children is important for triangulation and ancestor confirmation.

The method we use to confirm the common ancestor is that all of the descendants who match the tester on the same segment all also match each other. This greatly reduces the chances that these people are matching by chance. The more people in the triangulation group, the stronger the evidence. Of course, parental phasing or cross-matching, where available is an added confirmation bonus.

In our magenta inheritance example, we saw that three of the males and one of the females from three different descendants of the great-grandparents all carry at least a portion of that magenta segment of great-grandpa’s DNA.

Now, let’s take a look at a different scenario.

Why can’t siblings or close relatives be used as two of the three people needed for triangulation?

Aunts and Uncles

We know that the best way to determine if a match is valid is by parental phasing – your match also matching to one of your parents.

If both parents aren’t available, looking for close family matches in common with your match is the next hint that genealogists seek.

Let’s say that you and your match both match your aunt or uncle in common or their children.

You and your aunts or uncles matching DNA only pushes your common ancestor back to your grandparents.

At that point, your match is in essence matching to a segment that belongs to your grandparents. Your matches’ DNA, or your grandparents’ DNA could have randomly recombined and you and your aunt/cousins could be matching that third person by chance.

Ok, then, what about siblings?

Siblings

The most recent common ancestor (MRCA) of you and someone who also matches your sibling is your parents. Therefore, you and your sibling actually only count as one “person” in this scenario. In essence, it’s the DNA of your parent(s) that is matching that third person, so it’s not true triangulation. It’s the same situation as above with aunts/uncles, except the common ancestor is closer than your grandparents.

The DNA of your parents could have recombined in both siblings to look like a match to your match’s family. Or vice versa. Remember Parental Cross-Matching.

If you and a sibling inherited EXACTLY the same segment of your Mom’s and Dad’s DNA, and you match someone by chance – that person will match your sibling by chance as well.

In this example, you can see that both siblings 1 and 2 inherited the exact same segments of DNA at the same locations from both of their parents.

Of course, they also inherited segments at different locations that we’re not looking at that won’t match exactly between siblings, unless they are identical twins. But in this case, the inherited segments of both siblings will match someone whose DNA randomly combined with green or magenta dots in these positions to match a cross-section of both parents.

How False Positives Work and How to Avoid Them

We saw in our first example, displayed again above, what a valid triangulated match looks like. Now let’s expand this view and take a look more specifically at how false positive matches occur.

On the left-hand (blue) side of this graphic, we see four siblings that descend through their father from Great-grandpa who contributed that large magenta segment of DNA. That segment becomes reduced in descendants in subsequent generations.

In downstream generations, we can see gold, white and green segments being added to the DNA inherited by the four children from their ancestor’s spouses. Dad’s DNA is shown on the left side of each child, and Mom’s on the right.

  • Blue Children 1 and 2 inherited the same segments of DNA from Mom and Dad. Magenta from Dad and green from Mom.
  • Blue Child 3 inherited two magenta segments from Dad in positions 1 and 2 and one gold segment from Dad in position 3. They inherited all white segments from Mom.
  • Blue Child 4 inherited all gold segments from Dad and all white segments from Mom.

The family on the blue left-hand side is NOT related to the pink family shown at right. That’s important to remember.

I’ve intentionally constructed this graphic so that you can see several identical by chance (IBC) matches.

Child 5, the first pink sibling carries a white segment in position 1 from Dad and gold segments in positions 2 and 3 from Dad. From Mom, they inherited a green segment in position 1, magenta in position 2 and green in position 3.

IBC Match 1 – Looking at the blue siblings, we see that based on the DNA inherited from Pink Child 5’s parents, Pink Child 5 matches Blue Child 4 with white, gold and gold in positions 1-3, even though they weren’t inherited from the same parent in Blue Child 4. I circled this match in blue.

IBC Match 2 – Pink Child 5 also matches Blue Children 1 and 2 (red circles) because Pink Child 5 has green, magenta, and green in positions 1-3 and so do Blue Children 1 and 2. However, Blue Children 1 and 2 inherited the green and magenta segments from Mom and Dad respectively, not just from one parent.

Pink Child 5 matches Blue Children 1, 2 and 4, but not because they match by descent, but because their DNA zigzags back and forth between the blue children’s DNA contributed by both parents.

Therefore, while Pink Child 5 matches three of the Blue Children, they do not match either parent of the Blue Children.

IBC Match 3 – Pink Child 6 matches Blue Child 3 with white, magenta and gold in positions 1-3 based on the same colors of dots in those same positions found in Blue Child 3 – but inherited both paternally and maternally.

You can see that if we had the four parents available to test, that none of the Pink Children would match either the Blue Children’s mother or father and none of the Blue Children would match either of the Pink Children’s mother or father.

This is why we can’t use either siblings or close family relatives for triangulation.

Distant Cousins Are Best for Triangulation & Here’s Why

When triangulating with 3 people, the most recent common ancestor (MRCA) intersection of the closest two people is the place at which triangulation turns into only two lines being compared and ceases being triangulation. Triangle means 3.

If siblings are 2 of the 3 matching people, then their parents are essentially being compared to the third person.

If you, your aunt/uncle, and a third person match, your grandparents are the place in your tree where three lines converge into two.

The same holds true if you’re matching against a sibling pair on your match’s side, or a match and their aunt/uncle, etc.

The further back in your tree you can push that MRCA intersection, the more your triangulated match provides confirming evidence of a common ancestor and that the match is valid and not caused by random recombination.

That’s exactly what the descendants of Charles Dodson have been able to do through triangulation with multiple descendants from several of his children.

It’s also worth mentioning at this point that the reason autosomal DNA testing uses hundreds/thousands of base pairs in a comparison window and not 3 or 6 dots like in my example is that the probability of longer segments of DNA simply randomly matching by chance is reduced with length and SNP density which is the number of SNP locations tested within that cM range.

Hence a 7 cM/500 SNP minimum is the combined rule of thumb. At that level, roughly half of your matches will be valid and half will be identical by chance unless you’re dealing with endogamy. Then, raise your threshold accordingly.

Ok, So Where are We? A Triangulation Checklist for You!

I know this has been a relatively long educational article, but it’s important to really understand that testing close relatives is VERY important, but also why we can’t effectively use them for triangulation.

Here’s a handy-dandy summary matching/triangulation checklist for you to use as you work through your matches.

  • You inherit half of each of your parents’ DNA. There is no other place for you to obtain or inherit your DNA. There is no DNA fairy sprinkling you with DNA from another source:)
  • DNA does NOT skip generations, although in occasional rare circumstances, it may appear that this happened. In this situation, it’s incumbent upon you, the genealogist, to PROVE that an exception has occurred if you really believe it has. Those circumstances might be pedigree collapse or perhaps imputation. You’ll need to compare matches at vendors who provide a chromosome browser, triangulation, and full shared match list information. Never assume that you are the exception without hard and fast proof. We all know about assume, right?
  • Your siblings inherit half of your parents’ DNA too, but not the same exact half of your parent’s DNA that you other siblings did (unless they are identical twins.) You may inherit the exact same DNA from either or both of your parents on certain segments.
  • Your matches may match your parents on different or an additional segment that you did not inherit.
  • Every segment has an individual history. Evaluate every matching segment separately. One matching segment with someone could be maternal, one paternal, and one identical by chance.
  • You can confirm matches as valid if your match matches one of your parents, and you match one of your match’s parents. Parental Phasing is when your match matches your parent. Parental Cross-Matching is when you both match one of each other’s parents. To be complete, both people who match each other need to match one of the parents of the other person. This rule still holds even if you have a known common ancestor. I can’t even begin to tell you how many times I’ve been fooled.
  • 15-20% (or more with endogamy) of your matches will be identical by chance because either your DNA or your match’s DNA aligns in such a way that while they match you, they don’t match either of your parents.
  • Your siblings, aunts, and uncles will often inherit the same DNA as you – which means that identical by chance matches will also match them. That’s why we don’t use close family members for triangulation. We do utilize close family members to generate common match hints. (Remember the 20 cM shared match caveat at Ancestry)
  • While your siblings, aunts, and uncles are too close to use for triangulation, they are wonderful to identify ancestral matches. Some of their matches will match you as well, and some will not because your close family members inherited segments of your ancestor’s DNA that you did not. Everyone should test their oldest family members.
  • Triangulate your close family member’s matches separately from your own to shed more light on your ancestors.
  • Endogamy may interfere with parental phasing, meaning you may match because you and/or your match may have inherited some of the same DNA segment(s) from both sides of your tree and/or more DNA than might otherwise be expected.
  • Pedigree collapse needs to be considered when using parental phasing, especially when the same ancestor appears on both sides of your family tree. You may share more DNA with a match than expected.
  • Conversely, with pedigree collapse, your match may not match your parents, or vice versa, if a segment happens to have recombined in you in a way that drops the matching segments of your parents beneath the vendor’s match threshold.
  • While you will match all of your second cousins, you will only match approximately 90% of your third cousins and proportionally fewer as your relationship reaches further back in time.
  • Not being a DNA match with someone does NOT mean you’re NOT related to them, unless of course, you’re a second cousin (2C) or closer. It simply means you don’t carry any common ancestral segments above vendor thresholds.
  • At 2C or closer, if you’re not a DNA match, other alternative situations need to be considered – including the transfer/upload of the wrong person’s DNA file.
  • Imputation, a scientific process required of vendors may interfere with matching, especially in more distant relatives who have tested on different platforms.
  • Imputation artifacts will be less obvious when people are more closely related, meaning closer relatives can be expected to match on more and larger segments and imputation errors make less difference.
  • Imputation will not cause close relatives, meaning 2C or closer, to not match each other.
  • In addition to not supporting segment matching information, Ancestry down-weights some segments, removes some matching DNA, and does not show shared matches below 20cM, causing some people to misinterpret their lack of common matches in various ways.
  • To resolve questions about matching issues at Ancestry, testers can transfer/upload their DNA files to MyHeritage, FamilyTreeDNA, and GEDmatch and look for consistent matches on the same segment. Start and end locations may vary to some extent between vendors, but the segment size should be basically in the same location and roughly the same size.
  • GEDmatch does not use imputation but allows larger non-matching segments to combine as a single segment which sometimes causes extremely “generous” matches. GEDmatch matching is less reliable than FamilyTreeDNA or MyHeritage, but you can adjust the matching thresholds.
  • The best situation for matching is for both people to test at the same vendor who supports and provides segment data and a chromosome browser such as 23andMe, FamilyTreeDNA, or MyHeritage.
  • Siblings cannot be used for triangulation because the most recent common ancestor (MRCA) between you and your siblings is your parents. Therefore, the “three” people in the triangulation group is reduced to two lines immediately.
  • Uncles and aunts should not be used for triangulation because the most recent common ancestors between you and your aunts and uncles are your grandparents.
  • Conversely, you should not consider triangulating with siblings and close family members of your matches as proof of an ancestral relationship.
  • A triangulation group of 3 people is only confirmation as far back as when two of those people’s lines converge and reach a common ancestor.
  • Identical by chance (IBC) matching occurs when DNA from the maternal and paternal sides are mixed positionally in the child to resemble a maternal/paternal side match with someone else.
  • Identical by chance DNA admixture (when compared to a match) could have occurred in your parents or grandparent’s generation, or earlier, so the further back in time that people in a triangulation group reach, the more reliable the triangulation group is likely to be.
  • The larger the segments and/or the triangulation group, the stronger the evidence for a specific confirmed common ancestor.
  • Early families with a very large number of descendants may have many matching and triangulated members, even 9 or 10 generations later.
  • While exactly 50% of each ancestor’s DNA is not passed in each generation, on average, you will carry 7 cM of your ancestors 10 generations back in your tree. However, you may carry more, or none.
  • The percentage of matching descendants decreases with each generation beyond great-grandparents.
  • The ideal situation for triangulation is a significant number of people, greater than three, who match on the same reasonably sized segment (7 cM/500 SNP or larger) and descend from the same ancestor (or ancestral couple) through different children whose spouses in descendant generations are not also related.
  • This means that tree completion is an important factor in match/triangulation reliability.
  • Triangulating through different children of the ancestral couple makes it significantly less likely that a different unknown common ancestor is contributing that segment of DNA – like an unknown wife in a descendant generation.

Whew!!!

The Bottom Line

Here’s the bottom line.

  1. Don’t use close relatives to triangulate.
  2. Use parents for Parental Phasing.
  3. Use Parental Cross-Matching when possible.
  4. Use close relatives to look for shared common matches that may lead to triangulation possibilities.
  5. Triangulate your close relatives’ DNA in addition to your own for bonus genealogical information. They will match people that you don’t.
  6. For the most reliable triangulation results, use the most distant relatives possible, descended through different children of the common ancestral couple.
  7. Keep this checklist of best practices, cautions, and caveats handy and check the list as necessary when evaluating the strength of any match or triangulation group. It serves as a good reminder for what to check if something seems “off” or unusual.

Feel free to share and pass this article (and checklist) on to your genealogy buddies and matches as you explain triangulation and collaborate on your genealogy.

Have fun!!!

How to Download Your DNA Matching Segment Data and Why You Should

There are two or three types of data that testers may be able to download from DNA testing sites. Genealogy customers need to periodically download as much as possible.

  1. Raw data files needed for transferring DNA files from the company where you tested to other testing or analysis/comparison sites such as FamilyTreeDNA, MyHeritage, and GEDmatch for matching and other tools.
  2. Matching segment files which detail your matches, segment by segment with people whom you match.
  3. Match information files that provide you with additional information about your matches. What’s included varies by vendor.

This type of information is not uniformly available from all vendors, but is available as follows:

Vendor Raw Data File Matching Segment File Match Information File
FamilyTreeDNA Yes Yes Yes
MyHeritage Yes Yes Yes
23andMe Yes Yes Yes
Ancestry Yes No No
GedMatch Not a testing company, so no Yes Yes

I have provided step-by-step information about how to download your raw DNA data files and upload them to other vendors in a series of articles that you can find here.

Some of the answers in the table above need caveats because each vendor is different. Let’s take a look.

Matching Segment Files

In this article, I’ll provide information about how to download your matching segment and match information file(s).

Unfortunately, Ancestry does not provide any segment data at all, nor do they provide a way to download your match information. Third-party tools that did this for you have been banned by Ancestry, under threat of legal action, so this information is no longer available to Ancestry customers.

You can’t obtain this information from Ancestry, but you can transfer your DNA file to other vendors such as FamilyTreeDNA, MyHeritage and the third-party site, GEDmatch where you’ll receive additional matches. Some Ancestry matches will have transferred elsewhere as well, and you can take advantage of your matching segment information.

Why Do I Want a Matching Segment File?

The matching segment file provides you with information about exactly how and where you match each person.

Here’s an example that includes the match name, chromosome, start and end location of the match along with the total number of CentiMorgans (cM) and total SNPs in the matching segment. Your matching segment file consists of hundreds/thousands of rows of this information.

Determining who matches you on the same segment is important because it facilitates the identification of common ancestors. Segment matching is also the first step in triangulation which allows you to confirm descent from common ancestors with your matches.

I wrote about triangulation at each vendor in the following articles:

Matching and Triangulation help you sort out legitimate matches, and which ancestors that DNA segment comes from.

Sorting For Legitimate Matches

On each segment location of your DNA, you will match:

  • People from your Mom’s side
  • People from your Dad’s side
  • People that are identical by chance (IBC) where they match you because part of the DNA from your Mom’s side and part from your Dad’s side just happens to look like their DNA (or vice versa.)

You can see how matching works in this example of 10 DNA locations. You inherited half of your Mom’s DNA and half of your Dad’s.

  • Legitimate maternal matches to you on this segment will have all As in this location.
  • Legitimate paternal matches to you will have all Cs in this location.
  • Identical by chance matches will match you, because they have the same DNA as both of your parents that you carry – interspersed. They will not match either of your parents individually.

IBC matches DO technically match you, but accidentally. In other words, they are identical by chance (IBC) because they just happen to match the DNA of both of your parents intermixed. Conversely, you can match the DNA of their parents intermixed as well. Regardless of why, they are not a legitimate maternal or paternal match to you.

For example, you can see that the identical by chance (IBC) match to you, above, won’t match the legitimate maternal or legitimate paternal matches.

When comparing your matches on any segment, you’ll wind up with a group of people who match you and each other on your maternal side, a group on your paternal side, and “everyone else” who is IBC.

I wrote about IBD, identical by descent DNA and IBC, identical by chance DNA and how that works, here.

A downloadable segment match file allows you to sort all of your matches by chromosome and segment. That’s the first step in determining if your matches match each other – which is how to determine if people are legitimate matches or IBC.

Additionally, these files allow you to utilize features at DNAPainter along with the tools at DNAGedcom and Genetic Affairs.

Match Information File

There’s a second file you’ll want to download as well except at 23andMe who includes all of the information in one file. You’ll want to download these files from each vendor at the same time so they are coordinated and include the same matches from the same time.

Downloading the second file, your match information, provides additional information which will be helpful for your genealogy. The information in this file varies by vendor, but includes items such as, but not limited to:

  • Tree link
  • Haplogroup
  • Match date
  • Predicted Relationship Range
  • Actual Relationship
  • Total shared cM
  • Longest segment cM
  • Maternal or paternal bucket (FamilyTreeDNA)
  • Notes
  • Email
  • Family Surnames
  • Location
  • Percent of shared DNA

You never know when vendors are going to change something that will affect your matches, like 23andMe did last fall, so it’s a good idea to download periodically.

Downloading your segment match and match information files are free, so let’s do this.

Downloading Your Segment Match & Information Files

FamilyTreeDNA

Sign on to your account.

click images to enlarge

Under your Family Finder Autosomal DNA test results, click on Chromosome Browser.

On the chromosome browser page, at the top right, click on Download All Segments.

Caveat – if you access the chromosome browser through the Family Finder match page, shown below, you will receive the segment matches ONLY for the people you have selected.

After selecting specific matches, as shown above, the option on the chromosome browser page will only say “Download Segments.” It does NOT say “Download All Segments.”

Clicking on this link only downloads the segments that you match with those people, so always be sure to access “Download ALL Segments” directly through the chromosome browser selection on your Autosomal DNA Family Finder menu without going to your match page and selecting specific matches.

The segment download file includes only the segments, but not additional information, such as which side, maternal or paternal, those matches are bucketed to, surnames and so forth. You need to download a second file.

To download additional information about your matches, scroll to the very bottom of your Family Finder match page and click on either Download Matches or Download Filtered matches. If you’ve used a filter such as maternal or paternal, you’ll receive only those matches, so be sure no filters are in use to download all of your matches’ information.

Your reports will be downloaded to your computer, so save them someplace where you can find them.

MyHeritage

Sign in to your account and click on the DNA tab, then DNA Matches.

At the far right-hand side, you’ll see three little dots. Click on the dots and you’ll see the options to export both the entire DNA Matches list and the shared DNA segment info for all DNA Matches.

You’ll want to download both. The first file Is the DNA matches list.

To download your segment matches, select the second option, “Export shared DNA segment info…”

Your files will be emailed to you.

23andMe

At 23andMe, sign on to your account and click on “DNA Relatives” under the Ancestry tab.

You’ll see your list of matches. Scroll to the very bottom where you’ll see the link to “Download aggregate data.”

23andMe combines your segment and match information in one file.

Remember that at 23andMe, your matches are limited to 2000 (unless you’re a V5 subscriber), minus the number of people who have not opted in to Relative Sharing. Additionally, there will be a number of people in the download file whose names appear, but who don’t have any segment data. Those people opted-in to Relative Sharing, but not to share segment information.

For example, my download file has 2827 rows. Of those, 1769 are unique individuals, meaning that I have matches with multiple segments for 1058 people. This means that of my 2000 allowed matches, 231 (or more) did not opt-in for Relative Sharing. The “or more” means that 23andMe does not roll matches off the list if you have communicated with the person, so some people may actually have more than 2000 matches. It’s impossible to know how 23andMe approaches calculations in this case.

Of those 1769 unique individuals on my match list, 257, or 15% did not share segment information. I’d sure like for those to be automatically rolled off and replaced with the next 257 who do share. 1512 or roughly three-quarters, 75%, of my 2000 allowed matches are useful for genealogy.

Initially, when 23andMe made their changes last fall, they were reportedly limiting the download file number to 1000, but they have reversed that policy on the V3 and V4 chips. I downloaded files from both chip versions to confirm that’s true.

I don’t have the V5 chip subscription level, nor am I going to retest to do that, so I don’t know if V5 subscribers receive all 5000 of the allowed matches in their download file.

This is the perfect example of why it’s a good idea to download your match files periodically. 23andMe is the only testing vendor that restricts your matches and when they roll off your list, they are irretrievable.

Aside from that, safe is better than sorry. You never know when something will change at a vendor and you’ll wish you had downloaded your match files earlier.

GedMatch

GedMatch, a third-party vendor, provides lots of tools but isn’t intuitive and provides almost no tutorial or information about how to navigate or use their site. There are some YouTube videos and Kitty Cooper has written several how-to articles. GEDmatch has promised a facelift soon.

GEDmatch provides many tools for free, along with a Tier1 level which provides advanced features by subscription.

At GEDmatch, you can see up to 2000 matches for free, but you must be a Tier 1 subscription member to download your matches – and the download is restricted to your top 1000 matches.

There are two Tier 1 one-to-many comparison options that are very similar. For either, you’ll enter your kit number and make your selection. Given that you’re restricted to 1000 in the download, there is no reason to search for more than 1000 kits.

click to enlarge

Then, click on Visualization options

You will then see the list of visualization options which includes “List/CSV.”

Clicking on “List/CSV” provides you with options.

click to enlarge

You’ll want to select the Matched Segment List, and you can either select “Prevent Hard Breaks,” or not. Allowing hard breaks means that small non-matching regions between two matching segments is not ignored, and the two segments are reported as two separate segments – if they are large enough to be reported.

If you prevent hard breaks, non-matching regions of less than 500,000 thousand base positions are ignored, creating one larger blended segment. It’s my preference to allow hard breaks because I’ve seen too many instances of erroneously “blended” segments.

When your matching segment file is complete, you will be prompted to download to your computer.

Thanks to Genetic Affairs, I discovered an alternate way to obtain more than 1000 downloaded matches from GEDmatch.

GEDmatch Alternative Methodology

Genetic Affairs suggests using the DNA Segment Search with a minimum of 5000 kits, and to enable the option to “Prevent Hard Breaks.”

Do not close the session while GedMatch is processing or you’ll need to restart your query.

When finished click “Here” to download the file to your system.

Now you’re ready for part 2.

Next, you’ll want to select the Triangulation feature.

These functions take time, so you’ll be watching as the counter increases. Or maybe go eat dinner or research some genealogy.

I can hear the “Jeopardy countdown music

When finished, click on “Here” to download this second file.

Whew! Now you should have your segment and match information files from each company that supports this information and provides downloads.

Saving Files

I generally save my files by vendor and date. However, if you’re going to use the files for a special project – you may want to make a copy elsewhere. For example, I’m going to use these files for Genetic Affairs’ AutoSegment feature, so I’ve downloaded fresh files from each vendor on the same date and made a separate copy, stored in my Genetic Affairs folder. I’ll let you know how that goes😊

Bottom Line

  • Test at vendors that don’t accept transfers. Ancestry and 23andMe
  • Test at or transfer to the rest. FamilyTreeDNA, MyHeritage and GEDmatch
  • Unlock or subscribe to the advanced tools that include chromosome browsers, ethnicity, and more, depending on the vendor. FamilyTreeDNA, MyHeritage, GEDmatch
  • Upload or create trees at each vendor (except 23andMe who doesn’t support trees.)
  • Download as much information as you can from each vendor.
  • Work your matches through shared (in common with) matches, trees, segments, and clusters!

Have fun!!!

Genealogy Tree Replacement – Should I or Shouldn’t I?

Eventually, every serious genealogist faces the question of tree replacement at vendors – whether they should do it at all, and if so, how to proceed safely.

I’ve started to write this article a couple of times now, but I hesitate to publish articles when I haven’t tried all the different scenarios.

In this case, I haven’t, but I’m sharing what I DO know and why I’ve made the choice I have so that you can do your own research on the rest. Keep in mind that software changes from time to time, so information that you find online about this topic may be stale and it’s always best to confirm with the vendor in question before making a major change.

I use RootsMagic on my computer for my master tree, but I also have trees at Ancestry, MyHeritage, and Family Tree DNA so that I can derive the maximum benefit from those DNA/research platforms. This, of course, leads to the challenge of keeping multiple trees up to date – and the inevitable question of replacing trees.

Why Might You Want to Replace a Tree?

Let’s say you uploaded a tree from your genealogy software on your computer years ago to the various sites and now you’ve made a lot of changes.

Or, let’s say you didn’t want to upload your entire tree originally, so you created an abbreviated tree at the various sites.

Initially, that’s what I did, creating a direct line ancestors-only tree to upload. I had incorporated lots of non-documented information into my tree on my computer over the past many decades and I certainly didn’t want to share information online without verifying. I don’t want to be “THAT” person who spreads bad information, even unintentionally.

Now, let’s say you’ve continued your research and you want to share more than the original tree you uploaded or created at a vendor. You don’t want to update individual trees in 3 or 4 places though.

Or, let’s say that while you originally included an ancestors-only tree, now you want to add children and extend to current so that ThruLines at Ancestry, Theories of Family Relativity at MyHeritage and Phased Family Matching at Family Tree DNA can work more effectively. I uploaded my original “ancestors only” trees before those products were introduced.

What are the effects of deleting an existing tree and uploading a new tree at the various vendors? Should you or shouldn’t you?

Deleting Trees – BAD IDEA

First, if you ARE going to replace your tree, DON’T delete your existing tree first.

Deleting a tree breaks all of the links you’ve established – both to records, connected DNA kits, and some DNA tools. Any notes or groupings will be gone as well. Let’s look at each vendor individually.

Please keep in mind that there may be additional issues that I’m not aware of because I have not personally deleted my primary tree at any vendor.

Ancestry – If you delete an existing tree, your ThruLines will be gone and will likely regenerate differently with a new tree. Of course, that may be part of why you want to upload a new tree. Any documents you’ve saved to people in your existing tree will be gone and the links to those documents as well.

You can, of course, download the documents to your computer one by one. Downloading your tree does NOT download associated documents from Ancestry. Conversely, uploading trees doesn’t either, no matter where you upload it.

You can sync some desktop genealogy software applications with Ancestry. Both RootsMagic and Family Tree Maker synchronize your tree on your desktop with your Ancestry tree. Some software is better suited in synchronizing “both directions” than others. Syncing issues in user groups are quite prevalent.

Warning: I do not sync. If you’re going to try syncing between the two sources, I would recommend experimenting on a tree that is NOT your primary tree either at Ancestry or on your desktop, and reading extensively before attempting. Check user groups for the software in question to see what issues are being encountered. Also, be sure you have a current backup and check that synchronizing worked correctly before proceeding further.

If you delete your tree at Ancestry and upload a new tree, you will need to reconnect your DNA test or tests that you manage under the DNA tab, then the settings gear at right.

You’ll then need to redo any work such as TreeTags, notes, comments or saving records that you’ve already performed.

In essence, you’re uploading a blank slate.

MyHeritage – If you delete an existing tree, your Theories of Family Relativity. any Smart Matches, notes or records will be deleted along with any photos that you’ve linked. Furthermore, your DNA kits associated with people in your tree will lose their names when they become disconnected.

MyHeritage provides free software called Family Tree Builder for your desktop that does synchronize your tree with MyHeritage, including records.

MyHeritage has also collaborated with members of the Church of Jesus Christ of Latter-day Saints (LDS) to import a portion of their tree from FamilySearch into MyHeritage, and keep the trees synchronized.

Caveat: I have not used the Family Tree Builder software or the LDS sync feature.

If you delete your tree and upload a new tree, you’ll need to reconnect your DNA and that of any kits you manage to your tree. In order NOT to lose the names on your kits, do that in reverse order, meaning upload the new tree, reassign the DNA kit to the proper person on the new tree before deleting the old tree.  Beware of same name people when making this assignment.

You can reassign kits under the DNA tab, “Manage DNA kits,” then the three dots at right of the kit you want to reassign.

MyHeritage runs the Theories of Family Relativity (TOFR) algorithm periodically, every few months. You won’t get new TOFR until they run the software again. If you delete your tree, be prepared to wait on TOFR and redo everything you’ve currently done to anyone in your tree.

Just like with Ancestry, you’re uploading a blank slate.

Family Tree DNA – If you delete your tree, links to any DNA tests that you have connected to the appropriate people in your tree will be broken. Assigning family members to their proper place in your tree is required for Family Matching to function.

Family Matching utilizes the DNA of relatives you’ve linked in your tree by comparing in common segment matches between you, them, and other people to identify shared matches as maternal or paternal.

If you delete your tree and upload a new tree, you will need to reconnect your family members under the myTree tab at the top of your page. You can connect matches for the Family Finder autosomal test, Y DNA, and mitochondrial – whichever tests you’ve taken. If you only have a few matches that you’ve linked, relinking is no problem. If you have a lot, it’s more time-consuming.

Beware: Uploading very large trees is problematic due to file size and/or bandwidth. Call support before attempting.

My recommendation would be to include direct line ancestors, their spouses, descendants of those ancestors with spouses, but not unrelated (to you) spouses trees. In other words, your sister-in-law’s family isn’t relevant to your genetic genealogy.

23andMe – 23andMe does not support trees in the traditional sense, so uploading is not possible. You can, however, link to a current public tree that you’ve created elsewhere which can be viewed by your matches. To enter a tree link, look under the settings option (gear), then under “Edit enhanced profile.”

click to enlarge

When providing a link, be sure the tree you link to is public, not private.

Alternatives

At both Ancestry and MyHeritage, which are the two vendors who offer genealogical records and the ability to save records to people in your tree, you can upload multiple trees to the same account, presuming you have a current subscription.

If you don’t have the option to sync through your desktop software, or aren’t comfortable doing so, you can upload a more robust tree, but keep in mind that any records you save to the new tree will be lost if you delete that one in the future too.

If you’re going to upload a new tree, upload the new tree BEFORE deleting the old tree.

Connect any records person by person before deleting the old tree. That way, you don’t have to search for those records all over again.

I would let the old tree sit idle for some time so that you know you’ve retrieved everything. There’s no rush to delete the old tree.

Of course, a third methodology is to maintain multiple trees. That’s actually what I do. Here’s why.

My Methodology

I use the third alternative that certainly isn’t ideal, but I maintain four separate trees. I hear you cringing, but it really isn’t as awful as it sounds – and it’s infinitely better than redoing everything because I’m an active researcher and have thousands of connected records.

  • One tree lives on my computer where I update information and add new people, including speculative – although they are clearly noted as such. I also include massive notes – in some cases much longer than notes fields at vendors typically allow. I download documents to a folder on my computer with that person’s name from all subscription sites. I also write my 52 Ancestor’s articles using documentation from all sites that I compile in one place on my system. I also back up my system religiously, meaning every night, automatically.
  • One tree lives at Ancestry where I add links to my 52 Ancestor stories, save documents found at Ancestry and extend lines as I work on them. I don’t add extensive side branches. I have included all of my direct ancestors for at least 10 generations, or as far back as I can document, along with their children and grandchildren to enable Thrulines and green leaf hints.
  • One tree lives at MyHeritage where I upload and link many photos because I can easily enhance and colorize them and see my ancestors more clearly. I link ancestors in my tree to my published ancestor stories, save documents and use the same approach with the MyHeritage tree that I do with Ancestry, including extending families for my ancestors to enable the formation of Theories of Family Relatively. I methodically work all of my DNA matches and AutoClusters, recording my findings in comments.
  • One tree lives at Family Tree DNA where I include all of my direct line ancestors to about 10 generations. I extend each ancestral branch to include each DNA match as I identify our common ancestor and how my match fits into my tree. At Family Tree DNA, linking each match to the proper place in their tree enables additional people to be assigned as maternal or paternal which is their methodology of triangulation.

Summary – To Replace or Not to Replace?

Yes, I’m painfully aware that maintaining 4 trees is a pain in the patoot, but each vendor, except for 23andMe of course, provides important features that are sacrificed with the deletion and replacement of trees. The more you take advantage of the vendor’s features, the more difficult it is to redo your work.

The only tree I would consider replacing would be the one at Family Tree DNA because there are no genealogy records attached. Genealogy research records are not a business they’re in.

The only useful portion at FamilyTreeDNA is the ancestral line and the branches that descend to other testers and I simply add those branches manually as needed.

Having said that, I would never replace any tree, anyplace, with my “master tree” that lives on my computer system.

If you are considering replacing your tree, particularly at either Ancestry or MyHeritage, I strongly suggest that you contact support at the vendor in question to discuss the ramifications BEFORE you take that step.

Once done, there is no “undo” button, so be sure that you really want to make that decision and proceed in well-thought-out, measured, “no regret” steps.

Holiday DNA Sales Have Started Early

Wow – the sales started early this year! I understand that Black Friday has morphed into the month of November. I’m good with that!

I’m not really surprised because many people are spending more time at home and let’s face it, genealogy is a great at-home activity. I’m glad the sales are starting earlier and running longer because it encourages more people to become engaged.

Genealogy can even help you produce holiday gifts for others in a myriad of ways. Not just purchasing DNA kits for yourself and family members but creating stories or giving them a book you’ve created with photos of grandma and grandpa’s life, perchance.

Of course, DNA is a HUGE part of genealogy. Even if you’re not going to be able to see Uncle Joe this Thanksgiving, you can certainly have a fun Zoom session and document him swabbing or spitting for his DNA test! Make memories, one way or another

Let’s see what the vendors are offering. Then, be sure to read to the end for a surprise.

FamilyTreeDNA – Early Bird Holiday Sale

click to enlarge

FamilyTreeDNA has more products to offer than any of the other vendors with autosomal, Y DNA and mitochondrial DNA tests, each offering something unique.

Y DNA focuses only on your direct patrilineal (surname) line if you are a male. Mitochondrial DNA follows your matrilineal (mother’s mother’s mother’s) line for both sexes. The Family Finder autosomal test traces all ancestral lines. You can read a quick article about these different tests and how they work in this article:

The Family Finder test uses matches to known family members like parents, aunts, uncles and cousins to assign other matches who match both you and your family member to either maternal or paternal sides of your tree.

You can also use Genetic Affairs AutoCluster, AutoTree and AutoPedigree tools at FamilyTreeDNA to get even more mileage out of your DNA tests.

If you were an early tester with Y and mitochondrial DNA, you can upgrade now to a more robust test to receive more granular results.

click to enlarge

Have you noticed the ancient DNA articles I’ve been writing recently?

Your most refined haplogroup revealed only in the Big Y-700 or mitochondrial mtFull Sequence test allows you to compare your haplogroup with ancient samples most effectively. I promise you, there will be more articles upcoming! These are just pure joy, connecting back in time.

The FamilyTreeDNA sale ends November 24th. Please click here to order or upgrade.

MyHeritage

MyHeritageDNA includes lots of features that other vendors don’t have, such as integrated AutoClusters and Theories of Family Relativity (TOFR) which connects you and your matches through a network of common records and trees. TOFR is surprisingly accurate, either pointing the way to or identifying common ancestors.

I wrote about how to use these and other included tools to unravel your genealogy in this recent article, with a free companion webinar:

Additionally, MyHeritage has a strong focus in Europe that includes lots of European testers – perfect for people whose ancestors are emigrants from another country.

MyHeritageDNA is on sale now for $49, a $30 savings, plus free shipping if you purchase two or more kits. Please click here to order.

This sale ends November 25th.

Ancestry

Best known for their large database, AncestryDNA offers ThruLines which takes advantage of their database size to suggest common ancestors for you and your matches based on multiple trees. I wrote about ThruLines in this article:

The AncestryDNA test is on sale now for $59, a $40 savings, with free US shipping. Please click here to order.

Sale ends November 23rd.

23andMe

23andMe is best known in the genealogy community for the accuracy of their Ancestry Composition, known as ethnicity results, which they paint on your chromosomes.

23andMe also creates a “genetic tree” between you and your closest matches based on who does and who does not match each other, and how they match each other. I wrote about genetic trees and subsequently, how they solved one mystery in these two articles.

While the genetic tree technology isn’t perfected yet, it’s certainly the direction of the future and can provide insight into how you and others are related and where to look for them in your actual genealogy tree.

The 23andMe Ancestry only test is available for a 10% reduction in price at $88.95. Please click here to order.

Of course, 23andMe also offers a health product that includes the ancestry product.

The 23andMe Health + Ancestry test is available for $99, a saving of 50%. Please click here to order.

These sale prices end November 26th.

Surprise!!!

I have an early holiday gift for you too.

Beginning later this week, I’m publishing the first article in a new interactive series aptly named…drum roll…“DNA Tidbits.”

Indeed, there is fruit-of-the-vine to be harvested and that’s exactly what we are going to do – in small steps! Tidbits.

Just like everything else on this blog, it’s completely free of course and we are going to have lots of FUN!

Let me give you a hint – you’ll probably want to have test results at all of these companies because the Tidbits will be bouncing around a bit – so if you need to buy something, please click on the links below.

Thank you and I can’t wait to get started!

Search Techniques for Y and Mitochondrial DNA Test Candidates

I utilize DNA matches in various ways, some of which are a little unusual. In many cases, I mine autosomal DNA matches to search for people whose Y and mitochondrial DNA can provide descendants, including me and them, with additional insights into our common ancestors.

Y and mitochondrial DNA connects testers to their ancestors in ways that autosomal cannot. It’s a different type of DNA, not combined with the DNA of the other parent, so it’s not diluted and halved in each generation like autosomal DNA. Y and mitochondrial lines each descend from only one ancestral line, rich in historical information, with the ability to reach far back in time along with the ability to connect testers recently.

You First

The very first thing you can do to further your own research is to test yourself in three ways:

  • Autosomal DNA – Test at all 4 primary testing vendors, meaning FamilyTreeDNA, MyHeritage, Ancestry and 23andMe. The reason for testing at (or transferring to) multiple vendors is because they each have a unique focus and tools. Perhaps more importantly, they each have different people in their databases. Each testing company has benefits. FamilyTreeDNA has people who tested as long as 20 years ago and are no longer available for testing. MyHeritage has many European testers and you’ll find matches there that you won’t find elsewhere if your ancestors came from Europe. Ancestry has the largest database, but fewer advanced tools.
  • Full Sequence Mitochondrial DNA Available at FamilyTreeDNA, this test allows focus solely on your matrilineal line, meaning your mother’s mother’s mother’s line directly without confusion introduced by DNA from other lines.
  • Y DNA – For males only, also available at FamilyTreeDNA, provides focus on the direct patrilineal, or surname, line.

Obviously, if you haven’t upgraded your own Y and mitochondrial DNA tests to the highest level possible, the first thing you can do is to test or upgrade to the highest level where you receive the most refined amount of information.

(There’s a sale at FamilyTreeDNA right now, lasting until August 31, 2020, so it’s a great time to upgrade or order Y and mitochondrial. Check it out here.)

Different Kinds of DNA Serve Different Genealogical Purposes

Let’s look, briefly at how the various types of DNA tests benefit genealogy. Autosomal tests that you and family members can take will help you find other family members to test for specific Y and mitochondrial DNA lines.

Remember that you can test family members in addition to yourself, so if you’re a female, you may want to recruit your father or an uncle or brother to represent your patrilineal line DNA. If you’d like to read a brief article about the different types of DNA and their benefits, 4 Kinds of DNA for Genetic Genealogy is a good resource.

Y and Mito Pedigree.png

In this image, you can see that if you’re a male you can test for both your Y (blue-square) and mitochondrial DNA (red-circle) ancestral lines. If you’re a female, you can test only your mitochondrial DNA because females don’t have a Y chromosome. Both males and females, of course, can test (green) autosomal DNA which reveals a different type of connection to all of your ancestral lines, but with autosomal, you have to figure out which people match you on which lines.

Y and mitochondrial DNA provides you with a different type of information about laser-focused specific lines that you can’t obtain through autosomal testing, and reaches back in time far beyond the curtain when surnames were adopted.

personal pedigree

You personally can only test for the red-circle mitochondrial DNA line, and perhaps the blue-square Y DNA line if you’re a male. Unless you find family members to test for the Y and mitochondrial DNA of your ancestors, you’re leaving valuable information unresearched. That means all those colored boxes and squares that aren’t blue or red.

I’ve solved MANY brick walls using both Y and mitochondrial DNA, often in conjunction with autosomal.

Let’s take a look at each type of DNA testing a little more in-depth, so that you understand how each one works and why they are important to genealogy.

The Specifics

Y DNA – Y DNA descends through the direct male paternal line and is inherited by men only. You match against other Y DNA testers, hopefully finding surname links.

The Big Y test and upgrade at FamilyTreeDNA provides testers with all 111 traditional STR markers, plus another 589+ STRs available only in the Big Y test, plus a scan of the balance of the rest of the Y chromosome that is useful for genealogy. SNP results are increasingly being used for genealogy, in addition to STRs.

SNPs group men into genetic lineages and STRs help with defining and refining the closest generations when matching to each other. Often, the benefits of these two tests overlap, which is why I recommend that males test to the Big Y-700 level which provides 700+ STR markers plus all SNPs with mutations that define ancestral lineages.

Y DNA haplogroups, derived from SNPs, reveal the geographic part of the world where the lineage originated, such as Europe, the Americas, Asia and Africa, as well as a migration path across the continents based on where SNPs are and were historically found. Ancient DNA samples are being added to the database.

If you or a family member took an earlier Y DNA test, you can upgrade to the Big Y-700 today which provides you with matching for both the STR markers and separately, SNP markers, along with other genealogical tools.

You can order or upgrade your Y DNA here. Don’t forget family members accounts you may control. They may agree to have their kit upgraded too.

To upgrade, sign in to your account, and click on your desired upgrade level under Y DNA testing.

ymt y upgrade.png

Then click on upgrades.

ymt upgrade.png

I wrote about Y DNA in these recent articles:

I have more Y DNA articles planned for the future.

You can search for additional articles by going to the main page of this blog and enter “Y DNA” into the search box for additional articles already published.

Many features such as the matches maps, haplogroup origins and ancestral origins pages are the same for Y DNA results as mitochondrial DNA results. You can view mitochondrial articles here.

Mitochondrial DNA (mtDNA) – Mitochondrail DNA descends through the direct matrilineal line to both sexes of children. Everyone has mitochondrial DNA and it is inherited matrilineally by you from your mother, from her mother, from her mother, etc.

The FMS or full mitochondrial sequence DNA test tests the entire mitochondria that provides information about your direct matrilineal line. Family Tree DNA provides matching, which can sometimes lead to genealogical breakthroughs such as when I identified Lydia Brown, the mother of my Phoebe Crumley and then a couple years later, her mother, Phoebe Cole – via mitochondrial DNA. Those discoveries led us to her mother, Mary Mercy Kent, via genealogy records. All we needed was to punch our way through that initial brick wall – and mitochondrial DNA was our battering ram.

Additionally, you’ll receive a full haplogroup designation which allows you to look back in time before the advent of surnames and identifies the location where your ancestral line came from. For those seeking confirmation of Native American heritage, Y and mitochondrial DNA provides unquestionable proof and doesn’t wash out in time as autosomal DNA does.

Mitochondrial DNA includes haplogroups, matching and other genealogical tools.

You can order or upgrade you or a family member’s mitochondrial DNA here.

To upgrade, sign in to your account, and click on the desired upgrade level.

ymt mt upgrade

Then click on Upgrade if you’re upgrading or Add On if you’re ordering a new product for yourself.

ymt add ons upgrades.png

I wrote several mitochondrial DNA articles and compiled them into a summary article for your convenience.

Autosomal DNA – With autosomal DNA testing, you test once and there’s not an upgrade unless the vendor changes DNA testing platforms, which is rare. Each of the four vendors compares your DNA with all other people who’ve taken that test, or transferred from other companies. They match you with descendants from all of your ancestral lines. While the Y and mtDNA tests look back deeply in time as well as recently on one specific line, the autosomal tests are broad but not deep, spanning all ancestral lines, but limited to approximately 10 generations.

Each autosomal vendor has unique benefits and focus as well as shortcomings. I’ve listed the major points for each vendor relative to searching for Y and mitochondrial
DNA testing candidates. It’s important to understand the advantages of each vendor because it will help you understand the testers you are most likely to find in each database and may help focus your search.

FamilyTreeDNA’s Family Finder

  • Because FamilyTreeDNA archives customer’s DNA for 25 years, many people who tested Y or mitochondrial DNA 20 years ago and are now deceased upgraded to autosomal tests when they became available, or have been upgraded by family members since. These early testers often reach back another generation or so into the past to people born a century ago.
  • Advanced autosomal matching integrates with Y and mitochondrial DNA along with surname and other projects
  • Phased Family Matching provides the ability to link family members that match you to your tree which allows Family Tree DNA to group matches as paternal or maternal by utilizing matching segments to the same side of your family
  • Genetic Affairs, a third-party tool available for testers, builds common trees by reading the trees of your matches and comparing their trees with your own to identify common ancestors.
  • Genetic Affairs builds trees and pedigrees of your matches by searching for common ancestors in your MATCHES trees, even if you have no tree or don’t share those ancestors in your tree. This functionality includes Y and mitochondrial DNA if you have tested. This facilitates discovery of common ancestors of the people who you match, which may well lead you to ancestral discoveries as well.
  • Genetic Affairs offers clustering of your shared matches.
  • DNA file transfers are accepted from other vendors, free, with a $19 one time fee to unlock advanced tools.
  • Family Tree DNA has tested people worldwide, with a few location exceptions, since inception in the year 2000.
  • No direct triangulation, but Phased Family Matching provides maternal and paternal side triangulation when matches can be grouped into maternal and paternal sides.
  • Matches and segment match information are available for download.
  • The great thing about the advanced matching tool at Family Tree DNA is that it facilitates searching for people who match you on different kinds of tests, so it helps determine the potential closeness or distance of Y and mitochondrial relationships.

MyHeritage

Ancestry

  • Ancestry has the largest database, but did not begin testing until 2012 and did not test widely outside of the US/UK for some time. They now sell tests in 34 countries. Their testers are primarily focused in the US, Canada, England, Scotland, Ireland, and diaspora, with some overlap into Europe.
  • Ancestry offers ThruLines, a tool that connects testers whose DNA matches with common ancestors in their trees.
  • Ancestry does not provide a chromosome browser, a tool provided by the other three primary testing companies, nor do they provide triangulation or matching segment location information necessary to confirm that you match on the same segment with other people.
  • Ancestry has issued cease and desist orders to third party tools that perform functions such as clustering, autotrees, autopedigrees or downloading of matches. Ancestry does not provide these types of features for their users.
  • Ancestry does not accept transfers, so if you want to be in Ancestry’s database, you must test with Ancestry.
  • No Y or mitochondrial DNA testing available.
  • Match list is not available for download.

23andMe

  • The primary focus of 23andMe has always been health testing, so many people who test at 23andMe are not interested in genealogy.
  • 23andMe tests are sold in about 50 countries, but not worldwide.
  • 23andMe provides a chromosome browser, triangulation, segment information and a beta genetically constructed tree for close matches.
  • 23andMe does NOT support a genealogical tree either uploaded or created on their site, making tree comparisons impossible.
  • Genetic Affairs AutoCluster works at 23andMe, but AutoTree and AutoPedigree do not because 23andMe does not support trees.
  • 23andMe does make match files available for downloading.
  • No Y or mitochondrial DNA full testing or matching, but basic haplogroups are provided.
  • 23andMe caps matches at 2000, less any matches that have opted out of matching. My matches currently number 1770.
  • 23andMe does not accept transfers from other vendors, so if you want to be in their database, you must test with 23andMe.

Reaching Out to Find Testers

Unfortunately, we only carry the mitochondrial DNA of our mother and only men carry the Y DNA of their father. That means if we want to obtain that DNA information about our other family lines, we have to find people who descend appropriately from the ancestor in question and test that person.

I’ll share with you how I search for people who descend from each ancestor. After finding that person, I explain the situation, why the different kinds of tests are important, and offer a testing scholarship for the Y or mtDNA test at Family Tree DNA if they have not already taken that test. If they’ve tested their autosomal DNA elsewhere. I also explain that they can transfer their autosomal DNA file for free too and will receive new matches.

Here’s an article with links to upload/download instructions for each testing company. Feel free to share.

Each DNA testing company has different features, but you can use all of the companies to find people descended in the appropriate way from each ancestor. It’s easier if you know how to utilize each vendor’s tools to optimize your chances of success. I’m going to step you through the search process with hints and tips for each vendor.

Finding Y DNA and Mitochondrial DNA Candidates at FamilyTreeDNA

Because FamilyTreeDNA tests for both Y and mitochondrial DNA and has for 20 years, you stand a better chance of finding a candidate there who may have already tested, so that’s where I always begin.

Y DNA

Let’s say, for example, that I need to find a male descendant of my Ferverda line in order to ask them to test for Y DNA. The person can be descended from either a close relative, if I know of one, or a more distant relative that I don’t know, but need to find through searching other ways.

Search for Surnames and Projects at Family Tree DNA

First, search the FamilyTreeDNA website for your goal surname among existing testers, and then the appropriate surname project to see if your line has already tested.

ymt ferverda

On the main page, here, scroll down to until you see the prompt, above, and enter the surname. Be sure to consider alternate spellings too.

ymt ferverda search.png

In this case, I see that there is a Ferverda surname project with 18 people, and scrolling on down, that 4 people with this specific surname have tested.

ymt results.png

However, searching for an alternate spelling, the way it’s spelled in the Netherlands, I find that another 10 people have tested.

ymt ferwerda

Of course, some may be females, but they probably know males by that surname.

First, I’m going to check the Ferverda DNA project to see if a Ferverda male from my line has tested, and if so, to what level.

Click on the project link in the search results to see the DNA Project.

ymt admin.png

Note two things. First, the administrator’s name, as you may need this later. If you click on their name, their email address is displayed.

Second, click on DNA Results and select Y DNA if you’re presented with a choice. If the project has a public facing page, and most do, you’ll see something like the following information.

ymt project

Hey look, it’s my lucky day, given that both of these men descend from my ancestor. I happen to know that they have both taken the Big Y test, because I’m the project administrator, but you won’t know that. One way to get an idea is if they have less than the full 111 markers showing, they probably haven’t taken the Big Y, because a 111 upgrade is included in the Big Y test today.

You have three options at this point to contact one of these men:

  • See if the people are on your own autosomal DNA match list, or the match lists of kits from that family that you manage. If so, you can view their email address and contact them. If you haven’t yet tested autosomally, meaning the Family Finder test, at Family Tree DNA, you can transfer autosomal tests from elsewhere, for free, which means you will be viewing matches within hours or a couple days. Otherwise, you can order a Family Finder test, of course.
  • If the person with the Ferverda or Ferwerda surname is not on your Family Finder match list, reach out to the project administrator with a note to the person you want to contact and ask the administrator to forward your email to the project member.
  • If the administrator doesn’t answer, contact Family Tree DNA support and make the same request.

Checking Family Finder, one of those people is on my match list and I’m pretty sure it’s the right person, because when I click on his profile, not only does the haplogroup match the DNA project, but so does the ancestor.

ymt ferverda profile.png

Searching Family Finder

If there isn’t a DNA project match you can identify as your direct line ancestor, you can search your Family Finder matches for the surname to find a male with that surname. If your match has a tree, see if your ancestor or ancestral line is showing, then note whether they have taken a Y DNA test. They may have taken a Y test, but have not joined a project or not entered any “earliest known ancestor.” You can see which tests they’ve taken by looking at the little tabs above their profile on their tree, or on their profile card.

ymt ferverda tree

click to enlarge

Regardless, you’re now in touch with a potential contact.

Don’t dismiss females with that surname, or people who show that surname in their ancestral surname list. Women with the surname you’re looking for may have husbands, fathers, brothers or uncles who descend from the line you are seeking.

ymt search field.png

Utilize Genetic Affairs

My ace in the hole at FamilyTreeDNA is the Genetic Affairs AutoTree and AutoPedigree function.

Genetic Affairs is a third-party tool that you can use to assist with analysis of your matches at FamilyTreeDNA.

ymt genetic affairs

click to enlarge

At Genetic Affairs, selecting AutoTree generates trees where common ancestors of you and your matches, or your matches to each other, are displayed.

Your goal is to identify people descended from a common ancestor either directly paternally through all males for Y DNA or through all females to the current generation, which can be males, for mitochondrial DNA.

This article provides step-by-step instructions for the Genetic Affairs AutoTree and AutoPedigree functions.

Mitochondrial DNA

Mitochondrial DNA lineages are a bit more challenging because the surname changes every generation and DNA projects are unlikely to help.

The AutoTree/AutoPedigree report through Genetic Affairs serves the same purpose for mitochondrial DNA – building trees that intersect with a common ancestor. I generally drop the “minimum size of the largest DNA segment shared with the match” to 7 cM for this report. My goal running this report for this purpose isn’t to analyze autosomal DNA, but to find testing candidates based on how my matches descend from a specific ancestor, so I want to include as many matches as possible.

Family Finder Can Refine Y and mtDNA Information

In some cases, a Family Finder test can refine a potential relationship between two people who match on either Y DNA or mitochondrial. Additionally, you may want to encourage, or gift, specific matches with an upgrade to see if they continue to match you at higher testing levels.

Let’s say that two men match closely on a Y DNA test, but you’d like to know how far back the common ancestor lived.

ymt y matches.png

In this instance, you can see that the second match has taken a BIg Y and a Family Finder test, but the exact match (genetic distance of 0) has not. If the first individual cannot provide much genealogy, having them take a Family Finder test would help at least rule out a relationship through second cousins and would give you at least some idea how far back in time your common ancestor may have lived. If you do match on Family Finder, you receive an estimate of your relationship and can check the match level possibilities using the DNAPainter Shared cM Tool. If they upgrade to the Big Y-700 test, you may be able to differentiate your line from theirs, or confirm when and where a split occurred – or that there is no split.

This same autosomal testing scenario works for mitochondrial DNA.

For people who have taken both tests, Family Finder plus either Y or mitochondrial DNA, the Advanced Matching menu allows you to select combinations of tests and projects to query.

ymt advanced

click to enlarge

Finding Y and Mitochondrial DNA Candidates at MyHeritage

MyHeritage provides a wonderful tool called Theories of Family Relativity (TOFR) which finds common ancestors between you and your DNA matches, even if the ancestor is not in both trees, so long as a path exists between the two testers’ trees using other trees or research documents, such as census records. Of course, you’ll need to verify accuracy.

ymt tofr.png

At MyHeritage, select DNA Matches, then “Has Theory of Family Relativity.”

ymt mh ferverda

click to enlarge

You can see that I have 65 matches with a Theory of Family Relativity. Additionally, I can then search by surname.

ymt mh ferverda tree.png

click to enlarge

If I am looking for a Ferverda Y DNA candidate, I’ve found one thanks to this TOFR.

If you don’t find a tree where your match descends from your ancestor in the desired way, you can also widen the search by de-selecting Theories of Family Relativity and instead selecting SmartMatchs or shared surname combined with the name of your ancestor. There are many search and filter combinations available.

Let’s look at a mitochondrial DNA example where I’m searching for a descendant of Elizabeth Speaks who married Samuel Clarkson/Claxton.

ymt smartmatches

click to enlarge

In this case, I have one SmartMatch, which means that someone by the name of Elizabeth Speaks is found in my matches tree. I need to look to see if it’s the RIGHT Elizabeth Speaks and if my match descends through all females to the current generation. If so, I’ve found my mitochondrial DNA candidate and I can leave them a message.

You can also view SmartMatches (without a DNA match) from your own tree.

I can go to that person in my tree, click on their profile, and see how many SmartMatches I have. Clicking on 13 SmartMatches allows me to view those matches and I can click through to the connected trees.

ymt mt speaks.png

I can also click on “research this person” to discover more.

If you’re still not successful, don’t give up quite yet, because you can search in the records for trees that shows the person whom you seek. A SmartMatch is only created if the system thinks it’s the same person in both trees. Computers are far from perfect.

ymt mh trees

click to enlarge

Narrow the search as much as possible to make it easier to find the right individual, and then view the trees for descent in the proper manner.

Another wonderful tool at MyHeritage is the Genetic Affairs AutoCluster tool, built-in for MyHeritage users.

ymt mh cluster.png

The above cluster shows that one person carries the surname of Elizabeth’s husband. Viewing the accompanying spreadsheet for the AutoCluster run reveals that indeed, I’ve already identified a couple of matches as descendants of the desired ancestral couple. The spreadsheet shows links to their trees, my notes and more.

ymt cluster ss

Clusters show you where to look. Without the cluster, I had only identified two people as descendants of this ancestral couple. I found several more candidates to evaluate and two mitochondrial candidates are found in this cluster.

Finding Y and Mitochondrial DNA Candidates at 23andMe

23andMe is a little more tricky because they don’t support either uploaded or created user trees which makes finding descendants of a particular ancestor quite challenging.

However, 23andMe attempts to create a tree of your closer relatives genetically. which you can find under “DNA Relatives,” under the Ancestry tab, then “Family Tree” at the top.

I’ve added the names of my ancestors when I can figure out who the match is. Please note that this “created tree” is seldom exactly accurate, but there are often enough hints that you’ll be able to piece together at least some of the rest.

Here’s part of my “created” tree at 23andMe. I’m at far right.

ymt23 tree.png

click to enlarge

If you’re a genealogist, your eyes are going to glaze over about now, because the “people” aren’t in the correct locations – with maternal and paternal sides of the tree swapped. Also, please note, the locations in which they place people are estimates AND 23andMe does NOT take into account or provide for half-relationships.

That said, you can still obtain candidates for Y and mitochondrial DNA testing.

In this case, I’m searching for a mitochondrial DNA candidate for Evaline Miller, my grandfather’s mother or a Y DNA candidate for the Ferverda line.

I can tell by the surname of the male match, Ferverda, that he probably descends through a son, making him a Y DNA candidate.

Both Cheryl and Laura are possible mitochondrial DNA candidates for Evaline Miller, based on this tree, depending of course on how they actually do descend.

I can contact all of my matches, but in the event that they don’t answer, I’m not entirely out of luck. If I can determine EXACTLY how the match descends, and they descend appropriately for mitochondrial DNA, I can view the match to see at least a partial haplogroup. Since 23andMe only uses relatively close matches when constructing your tree, I’m relatively likely to recognize the names of the testers and may have them in my genealogy program.

By clicking on the Ferverda male, I can see that his Y haplogroup is I-Z58. That’s not nearly as refined as the Y DNA information at Family Tree DNA, but it’s something if I have nothing else and he doesn’t answer my query that would include the offer of a Y DNA test at Family Tree DNA.

ymt 23 hap

You can search at 23andMe by surname, but unless your match has entered their ancestral surnames and you recognize surnames that fit together, without a tree, unless your match answers your query, it’s very difficult to determine how you connect.

ymt 23 search.png

You can also view “Relatives in Common,” hoping to recognize someone you know as a common match.

ymt relatives in common

Please note that 23andMe does allow testers to enter a link to a tree, but few do.

ymt tree link.png

It’s worth checking, and be sure to enter your own tree link location.

Finding Y and Mitochondrial DNA Candidates at Ancestry

Ancestry’s ThruLines provides an excellent tool to find both Y and mitochondrial DNA participants.

Ancestry organizes their ThruLines by ancestor.

ymt thrulines

Select your desired Ancestor, someone whose DNA you seek. Clearly, Y DNA candidates are very easy because you simply choose any male ancestor in the correct line with the surname and look for a male match with the appropriate surname.

In this case, I’m selecting Martha Ruth Dodson, because I need her mitochondrial DNA.

ymt dodson.png

By clicking on her “card” I then see my matches assigned to her ThruLine.

Ymt ancestry thruline

Obviously, for mitochondrial DNA, I’m looking for someone descended through all females, so Martha’s daughter, Elizabeth Estes’s son Robert won’t work, but her daughter, Louisa Vannoy, at left is the perfect candidate. Thankfully, my cousin whom I match, at bottom left is descended through all females to the current generation, which can be male or female, so is a mitochondrial DNA candidate.

Finding Y and Mitochondrial DNA Candidates in Trees in General

I’ve utilized the combination of trees and DNA matches at FamilyTreeDNA through Genetic Affairs, Ancestry and MyHeritage, but you can also simply search for people who descend from the same ancestor based on their tree alone at the vendors who support trees as part of genealogical records. This includes both Ancestry and MyHeritage but also sites like Geneanet which is becoming increasingly popular, especially in Europe. (I have not worked extensively with Geneanet yet but plan to take it for a test drive soon.)

My reason for utilizing DNA matches+trees first is that the person has already been introduced to the concept that DNA can help with genealogy, and has obviously embraced DNA testing at least once. Not only that, with the assist of a Theory of Family Relativity, ThruLine or genetic Affairs automation tools, it’s much easier to find appropriate candidates.

Finding Y and Mitochondrial DNA Candidates at WikiTree

If you reach beyond DNA testing companies, WikiTree provides a valuable feature which allows people to specify that they descend from a particular ancestor, and if they have DNA tested, how they descend – including Y DNA, mitochondrial DNA and autosomal.

Here’s an example on the profile of John Y. Estes at WikiTree, one of my Estes ancestors.

ymt wiki.png

If someone descends appropriately for either Y or mitochondrial DNA line, and has taken that test, their information is listed.

In this case, there are two Y DNA testers and two autosomal, but no mitochondrial DNA which would have descended from John’s mother, of course.

You can click on the little green arrow icon to see how any DNA tested person descends from the ancestor whose profile you are accessing.

ymt wiki compare

Of course, the same surname for males is a good indication that the man in question is descended from that paternal line, but check to be sure, because some males took their mother’s surname for various reasons.

Here’s my line-of-descent from John Y. Estes. I can click on anyone else whose DNA information is listed as well to see how they descend from John. If they descend from John through all females, then they obviously descend from his wife though all females too which means they are a mitochondrial DNA candidate for her.

ymt wiki relationship.png

click to enlarge

Clicking on autosomal testers may reveal someone appropriately descended from the ancestor in question.

You can then click on any ancestor shown to view their profile, and any DNA tested descendants.

By clicking on name of the descendant whose DNA test you are interested in, you’ll be able to view their profile. Look for the Collaboration section where you can send them a private message that will be delivered by email from WikiTree.

ymt collaborate

Finding Y and Mitochondrial DNA Candidates at GedMatch

One final avenue to find Y and mitochondrial DNA candidates is through GedMatch, It’s probably the least useful option, though, because the major vendors all have some sort of tree function, except for 23andMe, and for some reason, many people have not uploaded GEDCOM files (trees) to GEDmatch.

Therefore, if you can find someone on GedMatch that tested elsewhere perhaps, such as LivingDNA who also provides a base haplogroup, or 23andMe, and they uploaded a GEDCOM file (tree) to GedMatch, you can utilize the GEDmatch “Find common ancestors” automated tree-matching functionality.

gedmatch mrca matches

click to enlarge

GEDmatch produces a list of your matches with common ancestors in their trees, allowing you to select the appropriate ancestor or lineage.

I wrote step-by-step instructions in the article, GEDmatch Introduces Automated Tree Matching.

Additionally, GEDmatch includes the Genetic Affairs AutoCluster tool in their Tier1 subscription offering,

ymt gedmatch.png

Gedmatch users who know their Y and mitochondrial haplogroup can enter that information in their profile and it will be reflected on the autosomal match list.

ymt gedmatch hap

Summary Chart

In summary, each testing vendor has a different focus and unique tools that can be used to search for Y and mitochondrial DNA candidates. Additionally, two other resources, WikiTree and GEDmatch, although not DNA testing vendors, can lead to discovering Y and mtDNA candidates as well.

I’ve created a quick-reference chart.

  Family Tree DNA MyHeritage Ancestry 23andMe Wikitree GEDmatch
Y DNA Test Yes No No No, partial haplogroup provided No test, listed by ancestor No, user entered
mtDNA Test Yes No No No, partial haplogroup provided No test, listed by ancestor No, user entered
DNA Projects Yes No No No Some Some
Strengths other than mentioned categories 20 year worldwide customer base, phased family matching European focus, SmartMatches, wide variety of filters Largest autosomal database Genetic tree beta DNA by ancestor May include users not found elsewhere who tested outside the major companies
Drawbacks No direct triangulation or tree matching No Genetic Affairs AutoTree or AutoPedigree Can’t download matches, no triangulation, clusters, AutoTree, or AutoPedigree No trees, 2000 match limit “One tree” may be incorrect Few trees, no AutoTree or AutoPedigree
Clustering Genetic Affairs Included in advanced tools No, prohibited Genetic Affairs N/A Included in Tier1
Genetic Affairs AutoTree & AutoPedigree Yes No No No, no tree support N/A No
Tree matching between users No, through Genetic Affairs Theories of Family Relativity ThruLines No Not directly MRCA common ancestors in Tier1

Now it’s your turn. Which Y and mitochondrial DNA lines can you find today?

Happy Hunting!

Download Your Ancestry Tree and Upload It Elsewhere for Added Benefit

Once you’ve created a tree at Ancestry, you can download or export that tree to upload it elsewhere, or for safekeeping at home.

Be aware that while the tree itself is downloaded, any documents you have attached through Ancestry are NOT downloaded along with the tree. To do that, you’ll need to sync your tree through RootsMagic or Family Tree Maker software on your home computer. That’s not the focus of this article.

This article provides step-by-step instructions on how to make a downloaded copy of your actual tree called a GEDCOM file. All vendors understand the GEDCOM file exchange format for family trees.

Uploading your tree elsewhere allows you to save time and enhances your experience at other vendors, such as Family Tree DNA, MyHeritage, and GEDmatch – all three of whom utilize your DNA test in addition to your tree in order to provide you with advanced tools and enhanced results.

These three vendors all use and provide segment information, in addition to trees, and matching is free if you transfer a DNA file. Transferring a DNA file and downloading a tree are two separate things.

To use DNA plus trees, there are two steps and I’ll cover both. First, let’s look at the benefits and the differences between those three vendors so you know what to expect.

Features Summary

Here’s a quick and very basic summary of the features and functions of each of the three companies that accept both GEDCOM and DNA file uploads and provide tree+DNA combination features.

  FamilyTreeDNA MyHeritage GEDmatch
Upload DNA File Yes Yes Yes
Free Matching Yes Yes Yes
Advanced Features $19 one-time unlock $29 one-time unlock $10 monthly subscription for Tier 1
Upload GEDCOM file* Yes Yes** Yes
Features Using GEDCOM File Phased Family Matching Theories of Family Relativity, Smart Matches, searches Comparison with matches’ trees
Genealogy Records Subscription Available No Yes No
DNA Testing in House Yes Yes No, upload only
Unique Features Assigning matches maternally and paternally, Y and mtDNA tests, archives your DNA Theories of Family Relativity, genealogical records, photo enhancement Ability to view your matches’ matches, advanced DNA tools

*There may be GEDCOM file size restrictions at some vendors.

**MyHeritage restricts free trees to 250 individuals, but you can add a records subscription to be able to work with a larger tree. You can read more, here. You can try a free subscription, here. I believe you can upload any size GEDCOM file without a subscription, but advanced functions such as record matches are restricted.

Unlike at the other vendors who focus exclusively on DNA, MyHeritage provides the resources to build and add branches to your tree, hence the restriction on how much is provided for free.

Both MyHeritage and FamilyTreeDNA also do their own DNA testing, so you don’t need to test at Ancestry. I wrote about testing and transfer strategies, here.

Regardless of where you test, you can download your tree from Ancestry and upload it to other sites.

I initially started out with only my direct ancestors in my tree, but you’ll want to include their children, minimally, in order to assist the vendors with tree comparisons, assuring that a person in two different trees is actually the same person, not just someone with the same or a similar name.

Downloading Your Ancestry Tree

After signing on to Ancestry, you’ll see the following at the upper left:

Download ancestry tree.png

Click on “Trees.”

Download Ancestry tree 2

You’ll see a list of all the trees you’ve created or that have been shared with you.

Click on the tree you want to download.

Download Ancestry tree settings.png

Next, you’ll see your tree displayed. Click on the down arrow to display options and click on “Tree Settings.”

Download Ancestry tree manage

You’ll see your tree settings, above. We’re focused ONLY on the area in the red box.

Downloading does NOT delete your tree. That is a different option.

Let’s look at a closeup of this section.

Do NOT Delete Your Tree

Delete means “throw away” permanently – you cannot retrieve the tree. Export means to make a copy, leaving the original intact on Ancestry.

Let’s look closer.

Download Ancestry export.png

People see the warning at the bottom, in the Delete tree section and they don’t realize that’s NOT referring to Export Tree.

See those little red arrows, above? They’re all pointing to minuscule tiny grey dividing lines between the Hint Preferences Section, the Manage Your Tree export function and the Delete your tree function.

The warning pertains to deleting your tree, not “Export tree.”

DO NOT DELETE YOUR TREE!!!

If you accidentally click on “Delete your tree,” you do get a confirmation step, shown below.

Download Ancestry delete

If you want to export or copy your tree for use elsewhere, do NOT press delete.

Download/Export Your Tree

To download your tree, click on the green Export tree button.

Download ancestry export 2.png

Export means to download a COPY of your tree, leaving the original on Ancestry.

Next, you’ll receive an “in process” message while your GEDCOM file is being created.

Download Ancestry generating

After you click on “Export tree,” you’ll receive this message.

Download Ancestry download.png

When finished, you’ll be able to click on “download tips” if you wish, then click on the green “Download your GEDCOM file.”

Save this file on your computer.

Uploading Your GEDCOM Elsewhere

Next, it’s time to upload your GEDCOM file to our three vendors. Please note that if you have previously uploaded a GEDCOM file to these vendors, you can replace that GEDCOM file, but that’s not always in your best interest.

We’ll look at GEDCOM replacement strategies and ramifications in each vendor’s section.

You’ll need to have an account set up with each vendor first.

Uploading to Family Tree DNA

At FamilyTreeDNA, the way to set up an account is to either order a DNA test, here, or transfer your autosomal DNA file from either 23andMe, Ancestry, or MyHeritage.

Transferring your DNA to FamilyTreeDNA

Transfer instructions for DNA from or to Family Tree DNA are found in the article, Family Tree DNA Step by Step Guide: How to Upload-Download DNA Files.

After you set up an account at Family Tree DNA, you can then upload your GEDCOM file.

Uploading Your GEDCOM File to FamilyTreeDNA

You can upload any GEDCOM file to FamilyTreeDNA.

Sign on to your account, then click on “myTREE” on the upper toolbar.

download ancestry ftdna

Click on “Tree Mgmt” at upper right.

Download ancestry ftdna gedcom.png

Next, you’ll see the “GEDCOM UPLOAD” beneath.

You can only upload one tree to Family Tree DNA. When you upload a new GEDCOM file, your current tree is deleted at the beginning of the process.

FamilyTreeDNA GEDCOM Replacement Strategy

You can replace a GEDCOM file with a newer, better one at FamilyTreeDNA, however, doing so means that any people you match who you’ve linked to their profiles in your original tree will need to be relinked.

Phased Family Matching where your matches are bucketed to maternal, paternal or both sides are created based on matches to people you’ve attached to their proper places in your tree.

If you have few or no matches attached to their profiles in your tree, then relinking won’t be a problem. If, like me, you’re taking full advantage of the ability to connect matches on your tree in order for your matches to be assigned maternally or paternally, then replacing your GEDCOM file would constitute a significant investment of time relinking.

The best plan for FamilyTreeDNA is to upload a robust tree initially with lines extended to current so that you can attach testers easily to their proper place in the tree.

If you didn’t do this initially, you’ll need to add the line to the tester from your common ancestor as you identify matches with common ancestors.

Uploading to MyHeritage

At MyHeritage, you can begin by ordering a DNA test, here, or transferring a DNA file from another vendor, here. You can also sign up to try a free genealogy subscription, here. From any of these three links, you’ll be prompted to set up an account.

Transferring Your DNA to MyHeritage

Instructions for transferring your DNA to MyHeritage can be found in the article, MyHeritage Step by Step Guide: How to Upload-Download DNA Files.

Uploading your GEDCOM File to MyHeritage

You can upload a GEDCOM file from any source to MyHeritage. After signing in to your account, you’ll see “Family tree” in the top task bar.

download ancestry myheritage

Click on Family tree and you’ll see “Import GEDCOM.”

Download Ancestry MyHeritage import.png

At MyHeritage you can have multiple GEDCOMs uploaded, but you’ll only be able to link your DNA test to your primary tree from which Theories of Family Relativity for you are generated.

MyHeritage GEDCOM Replacement Strategy

I have a full subscription to MyHeritage which allows an unlimited number in people of an unlimited number of trees. Smart Matches and other hints are generated for every person in every tree unless I disable that feature.

If I were to replace my primary GEDCOM file that is linked to my own DNA test, I would lose all of my Theories of Family Relativity which are only generated every few months. The next time Theories are run, I would receive new ones, but not before then.

Replacing an existing GEDCOM file at MyHeritage also means that you’ll lose links to any attached documents or photos that you’ve associated with that tree, additions of changed you’ve made, as well as Smart Matches to other people’s trees. You can, however, sync with MyHeritage’s own free desktop tree builder software.

Initially, a few years ago, I uploaded an ancestors-only tree to MyHeritage reaching back a few generations. Now I wish I had uploaded my entire GEDCOM file. I didn’t because I have unproven people and relationships in my computer file and I didn’t want to mislead anyone. However, Theories of Family Relativity uses descendants of your ancestors to connect across lines to other people. Having descendants of my ancestors in that tree wasn’t important at MyHeritage then, before that feature was introduced, but it is now.

Today, I’ve minimally added children and grandchildren of my ancestors, by hand. I use MyHeritage records and searches extensively, and I’d lose thousands of links if I replaced my primary GEDCOM file. Besides, when I review each person I add in the tree, it provides the opportunity of reviewing their information for accuracy and searching for new documents. I’ve discovered amazing things by using this one-at-a-time method for adding my ancestors’ children and descendants – including new information that led to a new ancestor just last week.

Uploading to GEDMatch

You’ll begin by setting up a free account at GEDmatch.

Download Ancestry gedmatch

GEDmatch isn’t a DNA testing site or a genealogy records site. It’s a DNA tools site that provides tools not found elsewhere. Sometimes matches found at Ancestry will download to GEDmatch but not elsewhere. Ancestry does not provide genealogically valuable segment information.

GEDmatch not only provides segment information and triangulation, as do FamilyTreeDNA and MyHeritage, but they also provide the ability for you to view the matches of your matches. This open-source approach is one of GEDmatch’s founding principles.

Uploading Your DNA to GEDmatch

After you sign in to GEDmatch, you’ll need to upload your DNA file from one of the vendors to GEDmatch. I strongly recommend using DNA files from the standard vendors, such as Ancestry, FamilyTreeDNA, MyHeritage or even LivingDNA. Other vendors use different chips or test different DNA locations and matching is sometimes less reliable.

download ancestry gedmatch upload DNA.png

After signing on to Gedmatch, you’ll see “Upload your DNA files.” Click on the link there for further prompts.

After uploading your DNA file, you’ll want to upload your GEDCOM file so that your matches can see if you have a common ancestor in your trees.

Upload Your GEDCOM file to GEDmatch

Scrolling down the sidebar below the “Upload Your DNA” section, past the various applications, you’ll see the Family Trees section.

download ancestry gedmatch gedcom

You’ll see the GEDCOM upload section, as well as various comparison tools. Click on “Upload GEDCOM (Fast)” to begin.

GEDmatch GEDCOM Replacement Strategy

You can replace your GEDCOM file at GEDmatch at will. Since all information at GEDmatch is generated real-time, meaning when the request is submitted, nothing is “saved” nor pre-generated, so you won’t lose anything by replacing a GEDCOM file, at least not as of this writing.

However, you’ll need to delete your current GEDCOM file first. You can do that by scrolling to the bottom of your User Profile area where your kit number is listed. (Mine is obscured, below.) You’ll see your GEDCOM file information.

download ancestry gedmatch resources.png

Click to manage resources, including deleting a GEDCOM file.

Currently, at GEDmatch, my direct line ancestral tree is sufficient.

Summary

Regardless of where you maintain your primary family tree, download or export it as a GEDCOM file and upload it elsewhere. You’re only cheating yourself (and your matches) if you don’t take advantage of all available tools.

Concepts: Chromosome Browser – What Is It, How Do I Use It, and Why Do I Care?

The goal of genetic genealogy is to utilize DNA matches to verify known ancestors and identify unknown ancestors.

A chromosome browser is a tool that allows testers to visualize and compare their DNA on each chromosome with that of their genetic matches. How to utilize and interpret that information becomes a little more tricky.

I’ve had requests for one article with all the information in one place about chromosome browsers:

  • What they are
  • How and when to use them
  • Why you’d want to

I’ve included a feature comparison chart and educational resource list at the end.

I would suggest just reading through this article the first time, then following along with your own DNA results after you understand the basic landscape. Using your own results is the best way to learn anything.

What Does a Chromosome Browser Look Like?

Here’s an example of a match to my DNA at FamilyTreeDNA viewed on their chromosome browser.

browser example.png

On my first 16 chromosomes, shown above, my 1C1R (first cousin once removed,) Cheryl, matches me where the chromosomes are painted blue. My chromosome is represented by the grey background, and her matching portion by the blue overlay.

Cheryl matches me on some portion of all chromosomes except 2, 6, and 13, where we don’t match at all.

You can select any one person, like Cheryl, from your match list to view on a chromosome browser to see where they match you on your chromosomes, or you can choose multiple matches, as shown below.

browser multiple example.png

I selected my 7 closest matches that are not my immediate family, meaning not my parents or children. I’m the background grey chromosome, and each person’s match is painted on top of “my chromosome” in the location where they match me. You see 7 images of my grey chromosome 1, for example, because each of the 7 people being compared to me are shown stacked below one another.

Everyplace that Cheryl matches me is shown on the top image of each chromosome, and our matching segment is shown in blue. The same for the second red copy of the chromosome, representing Don’s match to me. Each person I’ve selected to match against is shown by their own respective color.

You’ll note that in some cases, two people match me in the same location. Those are the essential hints we are looking for. We’ll be discussing how to unravel, interpret, and use matches in the rest of this article.

browser MyHeritage example.png

The chromosome browser at MyHeritage looks quite similar. However, I have a different “top 7” matches because each vendor has people who test on their platform who don’t test or transfer elsewhere.

Each vendor that supports chromosome browsers (FamilyTreeDNA, MyHeritage, 23andMe, and GedMatch) provides their own implementation, of course, but the fundamentals of chromosome browsers, how they work and what they are telling us is universal.

Why Do I Need a Chromosome Browser?

“But,” you might say, “I don’t need to compare my DNA with my matches because the vendors already tell me that I match someone, which confirms that we are related and share a common ancestor.”

Well, not exactly. It’s not quite that straightforward.

Let’s take a look at:

  • How and why people match
  • What matches do and don’t tell you
  • Both with and without a chromosome browser

In part, whether you utilize a chromosome browser or not depends on which of the following you seek:

  • A broad-brush general answer; yes or no, I match someone, but either I don’t know how are related, or have to assume why. There’s that assume word again.
  • To actually confirm and prove your ancestry, getting every ounce of value out of your DNA test.

Not everyone’s goals are the same. Fortunately, we have an entire toolbox with a wide range of tools. Different tools are better suited for different tasks.

People seeking unknown parents should read the article, Identifying Unknown Parents and Individuals Using DNA Matching because the methodology for identifying unknown parents is somewhat different than working with genealogy. This article focuses on genealogy, although the foundation genetic principles are the same.

If you’re just opening your DNA results for the first time, the article, First Steps When Your DNA Results are Ready – Sticking Your Toe in the Genealogy Water would be a great place to start.

Before we discuss chromosome browsers further, we need to talk about DNA inheritance.

Your Parents

Every person has 2 copies of each of their 22 chromosomes – one copy contributed by their mother and one copy contributed by their father. A child receives exactly half of the autosomal DNA of each parent. The DNA of each parent combines somewhat randomly so that you receive one chromosome’s worth of DNA from each of your parents, which is half of each parent’s total.

On each chromosome, you receive some portion of the DNA that each parent received from their ancestors, but not exactly half of the DNA from each individual ancestor. In other words, it’s not sliced precisely in half, but served up in chunks called segments.

Sometimes you receive an entire segment of an ancestor’s DNA, sometimes none, and sometimes a portion that isn’t equal to half of your parent’s segment.

browser inheritance.png

This means that you don’t receive exactly half of the DNA of each of your grandparents, which would be 25% each. You might receive more like 22% from one maternal grandparent and 28% from the other maternal grandparent for a total of 50% of the DNA you inherit from your parents. The other 50% of your DNA comes from the other parent, of course. I wrote about that here.

There’s one tiny confounding detail. The DNA of your Mom and Dad is scrambled in you, meaning that the lab can’t discern scientifically which side is which and can’t tell which pieces of DNA came from Mom and which from Dad. Think of a genetic blender.

Our job, using genetic genealogy, is to figure out which side of our family people who match us descend from – which leads us to our common ancestor(s).

Parallel Roads

For the purposes of this discussion, you’ll need to understand that the two copies you receive of each chromosome, one from each parent, have the exact same “addresses.” Think of these as parallel streets or roads with identical addresses on each road.

browser street.png

In the example above, you can see Dad’s blue chromosome and Mom’s red chromosome as compared to me. Of course, children and parents match on the full length of each chromosome.

I’ve divided this chromosome into 6 blocks, for purposes of illustration, plus the centromere where we generally find no addresses used for genetic genealogy.

In the 500 block, we see that the address of 510 Main (red bar) could occur on either Dad’s chromosome, or Mom’s. With only an address and nothing more, you have no way to know whether your match with someone at 510 Main is on Mom’s or Dad’s side, because both streets have exactly the same addresses.

Therefore, if two people match you, at the same address on that chromosome, like 510 Main Street, they could be:

  • Both maternal matches, meaning both descended from your mother’s ancestors, and those two people will also match each other
  • Both paternal matches, meaning both descended from your father’s ancestors, and those two people will also match each other
  • One maternal and one paternal match, and those two people will not match each other

Well then, how do we know which side of the family a match descends from, and how do we know if we share a common ancestor?

Good question!

Identical by Descent

If you and another person match on a reasonably sized DNA segment, generally about 7 cM or above, your match is probably “identical by descent,” meaning not “identical by chance.” In this case, then yes, a match does confirm that you share a common ancestor.

Identical by descent (IBD) means you inherited the piece of DNA from a common ancestor, inherited through the relevant parent.

Identical by chance (IBC) means that your mom’s and dad’s DNA just happens to have been inherited by you randomly in a way that creates a sequence of DNA that matches that other person. I wrote about both IBD and IBC here.

MMB stats by cM 2

This chart, courtesy of statistician Philip Gammon, from the article Introducing the Match-Maker-Breaker Tool for Parental Phasing shows the percentage of time we expect matches of specific segment sizes to be valid, or identical by descent.

Identical by Chance

How does this work?

How is a match NOT identical by descent, meaning that it is identical by chance and therefore not a “real” or valid match, a situation also known as a false positive?

browser inheritance grid.png

The answer involves how DNA is inherited.

You receive a chromosome with a piece of DNA at every address from both parents. Of course, this means you have two pieces of DNA at each address. Therefore people will match you on either piece of DNA. People from your Dad’s side will match you on the pieces you inherited from him, and people from your Mom’s side will match you on the pieces you inherited from her.

However, both of those matches have the same address on their parallel streets as shown in the illustration, above. Your matches from your mom’s side will have all As, and those from your dad’s side will have all Ts.

The problem is that you have no way to know which pieces you inherited from Mom and from Dad – at least not without additional information.

You can see that for 10 contiguous locations (addresses), which create an example “segment” of your DNA, you inherited all As from your Mom and all Ts from your Dad. In order to match you, someone would either need to have an A or a T in one of their two inherited locations, because you have an A and a T, both. If the other person has a C or a G, there’s no match.

Your match inherited a specific sequence from their mother and father, just like you did. As you can see, even though they do match you because they have either an A or a T in all 10 locations – the As and Ts did not all descend from either their mother or father. Their random inheritance of Ts and As just happens to match you.

If your match’s parents have tested, you won’t match either of their parents nor will they match either of your parents, which tells you immediately that this match is by chance (IBC) and not by descent (IBD), meaning this segment did not come from a common ancestor. It’s identical by chance and, therefore, a false positive.

If We Match Someone Else In Common, Doesn’t That Prove Identical by Descent?

Nope, but I sure wish it did!

The vendors show you who else you and your match both match in common, which provides a SUGGESTION as to your common ancestor – assuming you know which common ancestor any of these people share with you.

browser icw.png

However, shared matches are absolutely NOT a guarantee that you, your match, and your common matches all share the same ancestor, unless you’re close family. Your shared match could match you or your match through different ancestors – or could be identical by chance.

How can we be more confident of what matching is actually telling us?

How can we sort this out?

Uncertainties and Remedies

Here’s are 9 things you DON’T know, based on matching alone, along with tips and techniques to learn more.

  1. If your match to Person A is below about 20cM, you’ll need to verify that it’s a legitimate IBD match (not IBC). You can achieve this by determining if Person A also matches one of your parents and if you match one of Person A’s parents, if parents have tested.

Not enough parents have tested? An alternative method is by determining if you and Person A both match known descendants of the candidate ancestors ON THE SAME SEGMENT. This is where the chromosome browser enters the picture.

In other words, at least three people who are confirmed to descend from your presumptive common ancestor, preferably through at least two different children, must match on a significant portion of the same segment.

Why is that? Because every segment has its own unique genealogical history. Each segment can and often does lead to different ancestors as you move further back in time.

In this example, I’m viewing Buster, David, and E., three cousins descended from the same ancestral couple, compared to me on my chromosome browser. I’m the background grey, and they show in color. You can see that all three of them match me on at least some significant portion of the same segment of chromosome 15.

browser 3 cousins.png

If those people also match each other, that’s called triangulation. Triangulation confirms descent from a common ancestral source.

In this case, I already know that these people are related on my paternal side. The fact that they all match my father’s DNA and are therefore all automatically assigned to my paternal matching tab at Family Tree DNA confirms my paper-trail genealogy.

I wrote detailed steps for triangulation at Family Tree DNA, here. In a nutshell, matching on the same segment to people who are bucketed to the same parent is an automated method of triangulation.

Of course, not everyone has the luxury of having their parents tested, so testing other family members, finding common segments, and assigning people to their proper location in your tree facilitates confirmation of your genealogy (and automating triangulation.)

The ONLY way you can determine if people match you on the same segment, and match each other, is having segment information available to you and utilizing a chromosome browser.

browser MyHeritage triangulation.png

In the example above, the MyHeritage triangulation tool brackets matches that match you (the background grey) and who are all triangulated, meaning they all also match each other. In this case, the portion where all three people match me AND each other is bracketed. I wrote about triangulation at MyHeritage here.

  1. If you match several people who descend from the same ancestor, John Doe, for example, on paper, you CANNOT presume that your match to all of those people is due to a segment of DNA descended from John Doe or his wife. You may not match any of those people BECAUSE OF or through segments inherited from John Doe or his wife. You need segment information and a chromosome browser to view the location of those matches.

Assuming these are legitimate IBD matches, you may share another common line, known or unknown, with some or all of those matches.

It’s easy to assume that because you match and share matches in common with other people who believe they are descended from that same ancestor:

  • That you’re all matching because of that ancestor.
  • Even on the same segments.

Neither of those presumptions can be made without additional information.

Trust me, you’ll get yourself in a heap o’ trouble if you assume. Been there, done that. T-shirt was ugly.

Let’s look at how this works.

browser venn.png

Here’s a Venn diagram showing me, in the middle, surrounded by three of my matches:

  • Match 1 – Periwinkle, descends from Lazarus Estes and Elizabeth Vannoy
  • Match 2 – Teal, descends from Joseph Bolton and Margaret Claxton
  • Match 3 – Mustard, descends from John Y. Estes and Rutha Dodson

Utilizing a chromosome browser, autocluster software, and other tools, we can determine if those matches also match each other on a common segment, which means they triangulate and confirm common ancestral descent.

Of course, those people could match each other due to a different ancestor, not necessarily the one I share with them nor the ancestors I think we match through.

If they/we do all match because they descend from a common ancestor, they can still match each other on different segments that don’t match me.

I’m in the center. All three people match me, and they also match each other, shown in the overlap intersections.

Note that the intersection between the periwinkle (Match 1) and teal (Match 2) people, who match each other, is due to the wives of the children of two of my ancestors. In other words, their match to each other has absolutely nothing to do with their match to me. This was an “aha’ moment for me when I first realized this was a possibility and happens far more than I ever suspected.

The intersection of the periwinkle (Match 1) and mustard (Match 3) matches is due to the Dodson line, but on a different segment than they both share with me. If they had matched each other and me on the same segment, we would be all triangulated, but we aren’t.

The source of the teal (Match 2) to mustard (Match 3) is unknown, but then again, Match 3’s tree is relatively incomplete.

Let’s take a look at autocluster software which assists greatly with automating the process of determining who matches each other, in addition to who matches you.

  1. Clustering technology, meaning the Leeds method as automated by Genetic Affairs and DNAGedcom help, but don’t, by themselves, resolve the quandary of HOW people match you and each other.

People in a colored cluster all match you and each other – but not necessarily on the same segment, AND, they can match each other because they are related through different ancestors not related to your ancestor. The benefit of autocluster software is that this process is automated. However, not all of your matches will qualify to be placed in clusters.

browser autocluster.png

My mustard cluster above includes the three people shown in the chromosome browser examples – and 12 more matches that can be now be researched because we know that they are all part of a group of people who all match me, and several of whom match each other too.

My matches may not match each other for a variety of reasons, including:

  • They are too far removed in time/generations and didn’t inherit any common ancestral DNA.
  • This cluster is comprised of some people matching me on different (perhaps intermarried) lines.
  • Some may be IBC matches.

Darker grey boxes indicate that those people should be in both clusters, meaning the red and mustard clusters, because they match people in two clusters. That’s another hint. Because of the grid nature of clusters, one person cannot be associated with more than 2 clusters, maximum. Therefore, people like first cousins who are closely related to the tester and could potentially be in many clusters are not as useful in clusters as they are when utilizing other tools.

  1. Clusters and chromosome browsers are much less complex than pedigree charts, especially when dealing with many people. I charted out the relationships of the three example matches from the Venn diagram. You can see that this gets messy quickly, and it’s much more challenging to visualize and understand than either the chromosome browser or autoclusters.

Having said that, the ultimate GOAL is to identify how each person is related to you and place them in their proper place in your tree. This, cumulatively with your matches, is what identifies and confirms ancestors – the overarching purpose of genealogy and genetic genealogy.

Let’s take a look at this particular colorized pedigree chart.

Browser pedigree.png

click to enlarge

The pedigree chart above shows the genetic relationship between me and the three matches shown in the Venn diagram.

Four descendants of 2 ancestral couples are shown, above; Joseph Bolton and Margaret Claxton, and John Y. Estes and Rutha Dodson. DNA tells me that all 3 people match me and also match each other.

The color of the square (above) is the color of DNA that represents the DNA segment that I received and match with these particular testers. This chart is NOT illustrating how much DNA is passed in each generation – we already know that every child inherits half of the DNA of each parent. This chart shows match/inheritance coloring for ONE MATCHING SEGMENT with each match, ONLY.

Let’s look at Joseph Bolton (blue) and Margaret Claxton (pink). I descend through their daughter, Ollie Bolton, who married William George Estes, my grandfather. The DNA segment that I share with blue Match 2 (bottom left) is a segment that I inherited from Joseph Bolton (blue). I also carry inherited DNA from Margaret Claxton too, but that’s not the segment that I share with Match 2, which is why the path from Joseph Bolton to me, in this case, is blue – and why Match 2 is blue. (Just so you are aware, I know this segment descends from Joseph Bolton, because I also match descendants of Joseph’s father on this segment – but that generation/mtach is not shown on this pedigree chart.)

If I were comparing to someone else who I match through Margaret Claxton, I would color the DNA from Margaret Claxton to me pink in that illustration. You don’t have to DO this with your pedigree chart, so don’t worry. I created this example to help you understand.

The colored dots shown on the squares indicate that various ancestors and living people do indeed carry DNA from specific ancestors, even though that’s not the segment that matches a particular person. In other words, the daughter, Ollie, of Joseph Bolton and Margaret Claxton carries 50% pink DNA, represented by the pink dot on blue Ollie Bolton, married to purple William George Estes.

Ollie Bolton and William George Estes had my father, who I’ve shown as half purple (Estes) and half blue (Bolton) because I share Bolton DNA with Match 2, and Estes DNA with Match 1. Obviously, everyone receives half of each parent’s DNA, but in this case, I’m showing the path DNA descended for a specific segment shared with a particular match.

I’ve represented myself with the 5 colors of DNA that I carry from these particular ancestors shown on the pedigree chart. I assuredly will match other people with DNA that we’ve both inherited from these ancestors. I may match these same matches shown with DNA that we both inherited from other ancestors – for example, I might match Match 2 on a different segment that we both inherited from Margaret Claxton. Match 2 is my second cousin, so it’s quite likely that we do indeed share multiple segments of DNA.

Looking at Match 3, who knows very little about their genealogy, I can tell, based on other matches, that we share Dodson DNA inherited through Rutha Dodson.

I need to check every person in my cluster, and that I share DNA with on these same segment addresses to see if they match on my paternal side and if they match each other.

  1. At Family Tree DNA, I will be able to garner more information about whether or not my matches match each other by using the Matrix tool as well as by utilizing Phased Family Matching.

At Family Tree DNA, I determined that these people all match in common with me and Match 1 by using the “In Common With” tool. You can read more about how to use “In Common With” matching, here.

browser paternal.png

Family Matching phases the matches, assigning or bucketed them maternally or paternally (blue and red icons above), indicating, when possible, if these matches occur on the same side of your family. I wrote about the concept of phasing, here, and Phased Family Matching here and here.

Please note that there is no longer a limit on how distantly related a match can be in order to be utilized in Phased Family Matching, so long as it’s over the phase-matching threshold and connected correctly in your tree.

browser family tree dna link tree.png

Bottom line, if you can figure out how you’re related to someone, just add them into your tree by creating a profile card and link their DNA match to them by simply dragging and dropping, as illustrated above.

Linking your matches allows Family Matching to maternally or paternally assign other matches that match both you and your tree-linked matches.

If your matches match you on the same segment on the same parental side, that’s segment triangulation, assuming the matches are IBD. Phased Family Matching does this automatically for you, where possible, based on who you have linked in your tree.

For matches that aren’t automatically bucketed, there’s another tool, the Matrix.

browser matrix.png

In situations where your matches aren’t “bucketed” either maternally or paternally, the Matrix tool allows you to select matches to determine whether your matches also match each other. It’s another way of clustering where you can select specific people to compare. Note that because they also match each other (blue square) does NOT mean it’s on the same segment(s) where they match you. Remember our Venn diagram.

browser matrix grid.png

  1. Just because you and your matches all match each other doesn’t mean that they are matching each other because of the same ancestor. In other words, your matches may match each other due to another or unknown ancestor. In our pedigree example, you can see that the three matches match each other in various ways.
browser pedigree match.png

click to enlarge

  • Match 1 and Match 2 match each other because they are related through the green Jones family, who is not related to me.
  • Match 2 and Match 3 don’t know why they match. They both match me, but not on the same segment they share with each other.
  • Match 1 and Match 3 match through the mustard Dodson line, but not on the same segment that matches me. If we all did match on the same segment, we would be triangulated, but we wouldn’t know why Match 3 was in this triangulation group.
  1. Looking at a downloaded segment file of your matches, available at all testing vendors who support segment information and a chromosome browser, you can’t determine without additional information whether your matches also match each other.

browser chr 15.png

Here’s a group of people, above, that we’ve been working with on chromosome 15.

My entire match-list shows many more matches on that segment of chromosome 15. Below are just a few.

browser chr 15 all

Looking at seven of these people in the chromosome browser, we can see visually that they all overlap on part of a segment on chromosome 15. It’s a lot easier to see the amount of overlap using a browser as opposed to the list. But you can only view 7 at a time in the browser, so the combination of both tools is quite useful. The downloaded spreadsheet shows you who to select to view for any particular segment.

browser chr 15 compare.png

The critical thing to remember is that some matches will be from tyour mother’s side and some from your father’s side.

Without additional information and advanced tools, there’s no way to tell the difference – unless they are bucketed using Phased Family Matching at Family Tree DNA or bracketed with a triangulation bracket at MyHeritage.

At MyHeritage, this assumes you know the shared ancestor of at least one person in the triangulation group which effectively assigns the match to the maternal or paternal side.

Looking at known relatives on either side, and seeing who they also match, is how to determine whether these people match paternally or maternally. In this example below, the blue people are bucketed paternally through Phased Family Matching, the pink maternally, and the white rows aren’t bucketed and therefore require additional evaluation.

browser chr 15 maternal paternal.png

Additional research shows that Jonathan is a maternal match, but Robert and Adam are identical by chance because they don’t match either of my parents on this segment. They might be valid matches on other segments, but not this one.

browser chr 15 compare maternal paternal.png

  1. Utilizing relatives who have tested is a huge benefit, and why we suggest that everyone test their closest upstream relatives (meaning not children or grandchildren.) Testing all siblings is recommended if both parents aren’t available to test, because every child received different parts of their parents’ DNA, so they will match different relatives.

After deleting segments under 7 cM, I combine the segment match download files of multiple family members (who agree to allow me to aggregate their matches into one file for analysis) so that I can create a master match file for a particular family group. Sorting by match name, I can identify people that several of my cousins’ match.

browser 4 groups.png

This example is from a spreadsheet where I’ve combined the results of about 10 collaborating cousins to determine if we can break through a collective brick wall. Sorted by match name, this table shows the first 4 common matches that appear on multiple cousin’s match lists. Remember that how these people match may have nothing to do with our brick wall – or it might.

Note that while the 4 matches, AB, AG, ag, and A. Wayne, appear in different cousins’ match lists, only one shares a common segment of DNA: AB triangulates with Buster and Iona. This is precisely WHY you need segment information, and a chromosome browser, to visualize these matches, and to confirm that they do share a common DNA segment descended from a specific ancestor.

These same people will probably appear in autocluster groups together as well. It’s worth noting, as illustrated in the download example, that it’s much more typical for “in common with” matches to match on different segments than on the same segment. 

  1. Keep in mind that you will match both your mother and father on every single chromosome for the entire length of each chromosome.

browser parent matching.png

Here’s my kit matching with my father, in blue, and mother, in red on chromosomes 1 and 2.

Given that I match both of my parents on the full chromosome, inheriting one copy of my chromosome from each parent, it’s impossible to tell by adding any person at random to the chromosome browser whether they match me maternally or paternally. Furthermore, many people aren’t fortunate enough to have parents available for testing.

To overcome that obstacle, you can compare to known or close relatives. In fact, your close relatives are genetic genealogy gold and serve as your match anchor. A match that matches you and your close relatives can be assigned either maternally or paternally. I wrote about that here.

browser parent plus buster.png

You can see that my cousin Buster matches me on chromosome 15, as do both of my parents, of course. At this point, I can’t tell from this information alone whether Buster matches on my mother’s or father’s side.

I can tell you that indeed, Buster does match my father on this same segment, but what if I don’t have the benefit of my father’s DNA test?

Genealogy tells me that Buster matches me on my paternal side, through Lazarus Estes and Elizabeth Vannoy. Given that Buster is a relatively close family member, I already know how Buster and I are related and that our DNA matches. That knowledge will help me identify and place other relatives in my tree who match us both on the same segment of DNA.

To trigger Phased Family Matching, I placed Buster in the proper place in my tree at Family Tree DNA and linked his DNA. His Y DNA also matches the Estes males, so no adoptions or misattributed parental events have occurred in the direct Estes patrilineal line.

browser family tree dna tree.png

I can confirm this relationship by checking to see if Buster matches known relatives on my father’s side of the family, including my father using the “in common with” tool.

Buster matches my father as well as several other known family members on that side of the family on the same segments of DNA.

browser paternal bucket.png

Note that I have a total of 397 matches in common with Buster, 140 of which have been paternally bucketed, 4 of which are both (my children and grandchildren), and 7 of which are maternal.

Those maternal matches represent an issue. It’s possible that those people are either identical by chance or that we share both a maternal and paternal ancestor. All 7 are relatively low matches, with longest blocks from 9 to 14 cM.

Clearly, with a total of 397 shared matches with Buster, not everyone that I match in common with Buster is assigned to a bucket. In fact, 246 are not. I will need to take a look at this group of people and evaluate them individually, their genealogy, clusters, the matrix, and through the chromosome browser to confirm individual matching segments.

There is no single perfect tool.

Every Segment Tells a Unique History

I need to check each of the 14 segments that I match with Buster because each segment has its own inheritance path and may well track back to different ancestors.

browser buster segments.png

It’s also possible that we have unknown common ancestors due to either adoptions, NPEs, or incorrect genealogy, not in the direct Estes patrilineal line, but someplace in our trees.

browser buster paint.png

The best way to investigate the history and genesis of each segment is by painting matching segments at DNAPainter. My matching segments with Buster are shown painted at DNAPainter, above. I wrote about DNAPainter, here.

browser overlap.png

By expanding each segment to show overlapping segments with other matches that I’ve painted and viewing who we match, we can visually see which ancestors that segment descends from and through.

browser dnapainter walk back.png

These roughly 30 individuals all descend from either Lazarus Estes and Elizabeth Vannoy (grey), Elizabeth’s parents (dark blue), or her grandparents (burgundy) on chromosome 15.

As more people match me (and Buster) on this segment, on my father’s side, perhaps we’ll push this segment back further in time to more distant ancestors. Eventually, we may well be able to break through our end-of-line brick wall using these same segments by looking for common upstream ancestors in our matches’ trees.

Arsenal of Tools

This combined arsenal of tools is incredibly exciting, but they all depend on having segment information available and understanding how to use and interpret segment and chromosome browser match information.

One of mine and Buster’s common segments tracks back to end-of-line James Moore, born about 1720, probably in Virginia, and another to Charles Hickerson born about 1724. It’s rewarding and exciting to be able to confirm these DNA segments to specific ancestors. These discoveries may lead to breaking through those brick walls eventually as more people match who share common ancestors with each other that aren’t in my tree.

This is exactly why we need and utilize segment information in a chromosome browser.

We can infer common ancestors from matches, but we can’t confirm segment descent without specific segment information and a chromosome browser. The best we can do, otherwise, is to presume that a preponderance of evidence and numerous matches equates to confirmation. True or not, we can’t push further back in time without knowing who else matches us on those same segments, and the identity of their common ancestors.

The more evidence we can amass for each ancestor and ancestral couple, the better, including:

  • Matches
  • Shared “In Common With” Matches, available at all vendors.
  • Phased Family Matching at Family Tree DNA assigns matches to maternal or paternal sides based on shared, linked DNA from known relatives.
  • The Matrix, a Family Tree DNA tool to determine if matches also match each other. Tester can select who to compare.
  • ThruLines from Ancestry is based on a DNA match and shared ancestors in trees, but no specific segment information or chromosome browser. I wrote about ThruLines here and here.
  • Theories of Family Relativity, aka TOFR, at MyHeritage, based on shared DNA matches, shared ancestors in trees and trees constructed between matches from various genealogical records and sources. MyHeritage includes a chromosome browser and triangulation tool. I wrote about TOFR here and here.
  • Triangulation available through Phased Family Matching at Family Tree DNA and the integrated triangulation tool at MyHeritage. Triangulation between only 3 people at a time is available at 23andMe, although 23andMe does not support trees. See triangulation article links in the Resource Articles section below.
  • AutoClusters at MyHeritage (cluster functionality included), at Genetic Affairs (autoclusters plus tree reconstruction) and at DNAGedcom (including triangulation).
  • Genealogical information. Please upload your trees to every vendor site.
  • Y DNA and mitochondrial DNA confirmation, when available, through Family Tree DNA. I wrote about the 4 Kinds of DNA for Genetic Genealogy, here and the importance of Y DNA confirmation here, and how not having that information can trip you up.
  • Compiled segment information at DNAPainter allows you to combine segment information from various vendors, paint your maternal and paternal chromosomes, and visually walk segments back in time. Article with DNAPainter instructions is found here.

Transfer Your DNA

Transferring your DNA results to each vendor who supports segment information and accepts transfers is not only important, it’s also a great way to extend your testing collar. Every vendor has strengths along with people who are found there and in no other database.

Ancestry does not provide segment information nor a chromosome browser, nor accept uploads, but you have several options to transfer your DNA file for free to other vendors who offer tools.

23andMe does provide a chromosome browser but does not accept uploads. You can download your DNA file and transfer free to other vendors.

I wrote detailed upload/download and transfer instructions for each vendor, here.

Two vendors and one third party support transfers into their systems. The transfers include matching. Basic tools are free, but all vendors charge a minimal fee for unlocking advanced tools, which is significantly less expensive than retesting:

Third-party tools that work with your DNA results include:

All vendors provide different tools and have unique strengths. Be sure that your DNA is working as hard as possible for you by fishing in every pond and utilizing third party tools to their highest potential.

My mother used to say that patience is a virtue.

patience stones.jpg

I’m afraid I’m not naturally a very virtuous person, at least not where patience is concerned. I don’t seem to take after my ancestor, Patience Brewster (1600-1634.) Perhaps those “patience” genes didn’t make it to my generation. Or maybe Patience wasn’t very patient herself.

Not only does patience not come naturally to me, it’s more difficult for everyone during stressful times. People are anxious, nerves are frazzled and tempers are short. Have you noticed that recently?

I guess you could say that what we’ve been enduring, in terms of both health issues and/or preparation for the Covid-19 virus along with the economic rollercoaster – not to mention the associated politics, is stress-inducing.

patience stress.png

Let’s see:

  • Worry about a slow-motion epidemic steamrollering the population as it wraps around the world – check.
  • Worry about family members – check.
  • Worry about TP, hand sanitizer, food, medication and other supplies – check.
  • Worry about jobs and income – check.
  • Worry about retirement accounts and medical bills – check.
  • Worry about long-term ramifications – check.

Nope, no stress here. What about you?

And yes, I’m intentionally understated, hoping to at least garner a smile.

Once you’ve stocked up on what you need and decided to stay home out of harm’s way – or more to the point, out of germ’s way – how can you feel more patient and less stressed?

I have some suggestions!

patience stress relief.png

The Feel Better Recipe

First, just accept that once you’ve done what you can do to help yourself, which includes minimizing exposure – there’s little else that you can do. I wrote about symptoms and precautions, here. The best thing you can do is wash, stay home and remain vigilant.

If someone you know or love doesn’t understand why we need to limit or eliminate social interaction at this point, here’s an article that explains how NOT to be stupid, as well as an article here about what flattening the curve means and why social distancing is our only prayer at this point to potentially avoid disaster. We are all in this together and we all have a powerful role to play – just by staying at home.

Educating and encouraging others to take precautionary steps might help, but worrying isn’t going to help anything because you can’t affect much beyond your own sphere of influence. As much as we wish we could affect the virus itself, or increase the testing supply, or influence good decision-making by others, we generally can’t.

What can we do, aside from sharing precautionary information and hoping that we are “heard?”

We can try to release the worry.

patience zen.png

If you sit there thinking about releasing the worry, which means you’re focused on worrying – that’s probably not going to be very productive.

Neither is drinking your entire supply of Jack Daniels in one sitting – not the least of which is because you may need that as hand sanitizer down the road a bit. Oh, wait, hand sanitizer is supposed to be more than 60% alcohol, which would be 120 proof. Never mind, go ahead and drink the Jack Daniels😊

What you really need is a distraction. Preferably a beneficial distraction that won’t give you a hangover. Not like my distraction this past month when the washing machine flooded through the floor into the basement including my office below. No, not that kind of distraction.

Some folks can “escape the world,” in a sense, by watching TV, but I’m not one of those people. I need to engage my mind with some sort of structure and I want to feel like I’m accomplishing something. If you’re a “TV” person, you’re probably watching TV now and not reading this anyway – so I’m guessing that’s not my readership audience, by and large.

Beneficial Distractions

Here are 20 wonderful ideas for fun and useful things to do – and guess what – they aren’t all genealogy related. Let’s start with something that will make you feel wonderful.

labyrinth

  1. Take a walk – outside, but not around other people. Your body and mind will thank you. Your body likes to move and exercise generates beneficial feel-good endorphins, reducing anxiety. Remember to take hand sanitizer with you and open doors by pushing with your arm or hip, if possible. Also, if you need to get fuel for your vehicle, take disposable gloves to handle the pump. Disinfectant, soap and water is your friend – maybe your best friend right now.

patience books.png

  1. Read a book. Escapism, pure and simple. I have a stack of books just waiting. If you don’t, you can download e-books to your Kindle or iPad or phone directly from Amazon without going anyplace or have books delivered directly to your door. Try Libby Copeland’s The Lost Family, which you can order here. It’s dynamite. (My brother and my story are featured, which I wrote about here.) If you’d like DNA education, you can order Diahan Southard’s brand new book, Your DNA Guide: Step by Step Plans, here. I haven’t read Diahan’s book, but I’m familiar with the quality of her work and don’t have any hesitation about recommending it. (Let me know what you think.) And hey, you don’t even need hand sanitizer for this!

patience check box.png

  1. Check your DNA matches at all the vendors where you’ve tested. If you don’t check daily, now would be a good time to catch up. Not just autosomal matches, but also Y and mitochondrial at Family Tree DNA. Those tests often get overlooked. Maybe some of your matches have updated their trees or earliest known ancestor information.

patience tree.png

  1. Speaking of trees, update your trees on the three DNA/genealogy sites that support trees: FamilyTreeDNA, MyHeritage and Ancestry. Keeping your tree up to date through at least the 8th generation (including their children) enables the companies to more easily connect the dots for their helpful tools like Phased Family Matching aka bucketing at FamilyTreeDNA, Theories of Family Relativity aka TOFR at MyHeritage and ThruLines at Ancestry.

patience connect.png

  1. Connect your known matches to their appropriate place on your tree at Family Tree DNA, as illustrated above. This provides fuel for Family Tree DNA to be able to designate your matches as maternal or paternal, even if your mother and father haven’t tested. In this case, I’ve connected my first cousin once removed who matches me in her proper location in my tree. People who match my cousin and I both are assigned to my maternal bucket.

patience y dna.pngpatience mtdna.png

  1. Order or upgrade a Y DNA or mitochondrial DNA test or a Family Finder autosomal test for you or a family member at Family Tree DNA. Upgrades, shown above, are easy if the tester has already taken at least one test, because DNA is banked at the lab for future orders. You don’t have to go anyplace to do this and DNA testing results and benefits last forever. Your DNA works for you 24x7x365.

patience join project.png

patience projects.png

  1. Join a free project at FamilyTreeDNA. Those can be surname projects, haplogroup projects, regional projects such as Acadian AmeriIndian and other interest topics like American Indian. You can search or browse for projects of interest and collaborate with others. Projects are managed by volunteer administrators who obviously have an interest in the project’s topic.

patience match.png

  1. At each of the vendors, find your highest autosomal match whom you cannot place as a relative. Work on their line via tree construction and then utilizing clustering using Genetic Affairs. I wrote about Genetic Affairs, an amazing tool, here, which you can try for free.

patience familysearch wiki.png

patience claiborne.png

  1. Check the FamilySearch WIKI for your genealogy locations by googling “Claiborne County, Tennessee FamilySearch wiki” where you substitute the location of where you are searching for “Claiborne County, Tennessee.” FamilySearch is free and the WIKI includes resources outside of FamilySearch itself, including paid and other free sites.

patience familysearch records.png

  1. While you’re at it, if you haven’t already, create a FamilySearch account and create or upload a tree to FamilySearch. It will be connected to branches of existing trees to create one large worldwide tree. Yes, you’ll be frustrated in some cases because there are incorrect ancestors sometimes listed in the “big tree” – BUT – there are procedures in place to remediate that situation. The important aspect is that FamilySearch, which is free, provides hints and resources not available any other place for some ancestors. Not long ago, I found a detailed estate packet that I had no idea existed – for a female ancestor no less. You can search at FamilySearch for ancestors, genealogies, records and in other ways. New records become available often.  This will keep you occupied for days, I promise!

Patience Journal.png

  1. Begin a Novel Coronavirus Covid-19 Pandemic journal. Think of your descendants 100 years in the future. Wouldn’t you like to know what your great-grandparents were doing during the 1918 Spanish Flu Pandemic? Or even their siblings or neighbors, because that was likely similar to what your ancestors were doing as well. You don’t have to write much daily – just write. Not just facts, but how you feel as well. Are you afraid, concerned specifically about someone? What’s going on with you – in your mind? That’s the part of you that your descendants will long to know a century from now.

Quilt rose

  1. Create something with your hands. I made a quilt this week for an ailing friend, unrelated to this epidemic. No, I didn’t “have time” to do that, but I made time because this quilt is important, and I know they need the “get well’’” wishes and love that quilt will wrap them in. It always feels good to do something for someone else.

patience gardening.jpg

  1. Garden, or in my case, that equates to pulling weeds. Not only is weeding productive, you can work off frustration by thinking about someone or something that upsets you as you yank those weeds out by their roots. Of course, that means you’ll have to first decide what is, and is not, a weed😊. That could be the toughest part.

patience smart matches.png

  1. At MyHeritage, you can use Irish records for free this month, plus try a free subscription, here in order to access all the rest of the millions of records available at MyHeritage. Check for Smart Matches for ancestors, shown above, and confirm that they are accurate, meaning that the ancestor the other person has in their tree is the same person as you have in your tree – even if they aren’t exactly identical. You don’t need to import any of their information, and I would suggest that you don’t without reviewing every piece of information individually. Confirming Smart Matches helps MyHeritage build Theories of Family Relativity – not to mention you may discover additional information about your ancestors. While you’re checking Smart Matches, who ARE those other people with your grandmother in their tree. Are they relatives who might have information that you don’t? This is a good opportunity to reach out. And what are those 12 pending record matches? Inquiring minds want to know. Let’s check.
patience newspapers

Click to enlarge.

  1. Check either NewsPapers.com or the Newspaper collection at MyHeritage, or both, systematically, for each ancestor. You never know what juicy tidbits you might discover about your ancestors. Often, things “forgotten” by families are the informative morsels you’ll want to know and are hidden in those local news articles. These newsy community newspapers bring the life and times of our ancestors to light in ways nothing else can. Wait, what? My Brethren ancestor, Hiram Ferverda, pleaded guilty to something??? I’d better read this article!

patience interview.png

  1. Interview your relatives. Make a list of questions you’d like for them to answer about themselves and the most distant common ancestors that they knew, or knew about. You can conduct interviews without being physically together via the phone or Skype or Facetime. Document what was said for the future, in writing, and possibly by recording as well. After someone has passed, hearing their voice again is priceless.

Upload download

  1. Transfer your DNA file to vendors that accept transfers, getting more bang for your testing dollars by finding more matches. 23andMe and Ancestry don’t accept transfers.  At MyHeritage and FamilyTreeDNA, transfers are free and so is matching, but advanced tools require a small unlock fee. I wrote a step-by-step series about how to transfer, here. Each article includes instructions for transferring from or to Ancestry, MyHeritage, 23andMe and FamilyTreeDNA. Don’t forget to upload to GedMatch for additional tools.

patience brick wall.jpg

  1. Focus on your most irritating brick wall and review what records you do, and don’t have that could be relevant. That would include local, county, state and federal records, tax lists, census, church records and minutes and local histories if they exist. Have you called the local library and asked about vertical files or other researchers? What about state archive resources? Don’t forget activities like google searches. Have you utilized all possible DNA clues, including Y DNA and mitochondrial DNA, if applicable? How about third-party tools like Genetic Affairs and DNAgedcom?

patience DNApainter.png

  1. Try DNAPainter, for free. Painting your chromosomes and walking those segments back in time to your ancestors from whom they descended is so much fun. Not to mention you can integrate ethnicity and now traits, too. I’ve written instructions for using using DNAPainter in a variety of ways, here.

patience webinars.png

  1. Expand your education by watching webinars at Legacy Family Tree Webinars. Many are free and a yearly subscription is very reasonable. Take a look, here.

patience bucket.png

  1. Spring cleaning your house or desk. Ewww – cleaning – the activity that is never done and begins undoing itself immediately after you’ve finished? Makes any of the above 20 activities sound wonderful by comparison, right? I agree, so pick one and let’s get started!

Let me know what you find. Write about your search activities and discoveries in your Pandemic journal too.

DNA Testing Sales Decline: Reason and Reasons

If you’re involved in genetic genealogy, you’ve probably noticed the recent announcements by both 23andMe and Ancestry relative to workforce layoffs as a result of declining sales.

Layoffs

In January, 23andMe announced that it was laying off 100 people which equated to 14% of its staff.

Following suit, Ancestry this week announced that they are laying off 100 people, 6% of their work force. They discuss their way forward, here.

One shift of this type can be a blip, but two tends to attract attention because it *could* indicate a trend. Accordingly, several articles have been written about possible reasons why this might be occurring. You can read what TechCrunch says here, Business Insider here, and The Verge, here.

Depending on who you talk to and that person’s perspective, the downturn is being attributed to:

  • Market Saturation
  • No Repeat Sales
  • Privacy Concerns
  • FAD Over

Ok, So What’s Happening?

Between Ancestry and 23andMe alone, more than 26 million DNA tests have been sold, without counting the original DNA testing company, FamilyTreeDNA along with MyHeritage who probably have another 4 or 5 million between them.

Let’s say that’s a total of 30 million people in DNA databases that offer matching. The total population of the US is estimated to be about 329 million, including children, which means that one person in 10 or 11 people in the US has now tested. Of course, DNA testing reaches worldwide, but it’s an interesting comparison indicating how widespread DNA testing has become overall.

This slowing of new sales shouldn’t really surprise anyone. In July 2019, Illumina, the chip maker who supplies equipment and supplies to the majority of the consumer DNA testing industry said that the market was softening after a drop in their 2019 second quarter revenue.

Also last year, Ancestry and MyHeritage both announced health products, a move which would potentially generate a repeat sale from someone who has already tested their DNA for genealogy purposes. I suspected at the time this might be either a pre-emptive strike, or in response to slowed sales.

In November 2019, Family Tree DNA announced an extensive high-end health test through Tovana which tests the entire Exome, the portion of our DNA useful for medical and health analysis.

In a sense, this health focus too is trendy, but moves away from genealogy into an untapped area.

23andMe who, according to their website, has obtained $791 million in venture capital or equity funding has always been focused on medical research. In July of 2018 GlaxoSmithKline infused $300 million into 23andMe in exchange for access to DNA results of their 5 million customers who have opted-in to medical research, according to Genengnews. If you divide the 300 million investment by 5 million opted-in customers, 23andMe received $60 per DNA kit.

That 5 million number is low though, based on other statements by 23andMe which suggests they have 10 million total customers, 80% of which opt-in for medical research. That would be a total of 8 million DNA results available to investors.

Divide $791 million by 8 million kits and 23andMe, over the years, has received roughly $99 for each customer who has opted in to research.

We know who Ancestry has partnered with for research, but not how much Ancestry has received.

There’s very big money, huge money, in collaborating with Big Pharma and others. Given the revenue potential, it’s amazing that the other two vendors, Family Tree DNA and MyHeritage, haven’t followed suit, but they haven’t.

Additionally, in January, 23andMe sold the rights to a new drug it developed in-house as a potential treatment for inflammatory diseases for a reported (but unconfirmed by 23andMe) $5 million.

It’s ironic that two companies who just announced layoffs are the two who have partnered to sell access to their opted-in customers’ DNA results.

My Thoughts

I’ve been asked several times about my thoughts on this shift within the industry. I have refrained from saying much, because I think there has been way too much “hair on fire” clickbait reporting that is fanning the flames of fear, not only in the customer base, but in general.

I am sharing my thoughts, and while they are not entirely positive, in that there is clearly room for improvement, I want to emphasize that I am very upbeat about this industry as a whole, and this article ends very positively with suggestions for exactly that – so please read through.

Regardless of why, fewer new people are testing which of course results in fewer sales, and fewer new matches for us.

My suspicion is that each of the 4 reasons given above is accurate to some extent, and the cumulative effect plus a couple of other factors is the reason we’re seeing the downturn.

Let’s take a look at each one.

Market Saturation

Indeed, we’ve come a very long way from the time when DNA was a verboten topic on the old RootsWeb mailing lists and boards.

Early DNA adopters back then were accused of “cheating,” and worse. Our posts were deleted immediately. How times have changed!

As the technology matured, 23andMe began offering autosomal testing accompanied by cousin matching.

Ancestry initially stepped into the market with Y and mitochondrial DNA testing, but ultimately destroyed that database which included Y and mitochondrial DNA results from Relative Genetics, a company they had previously acquired. People in those databases, as well as who had irreplaceable samples in Sorenson, which Ancestry also purchased and subsequently took offline permanently have never forgotten.

Those genealogists have probably since tested at Ancestry, but they may be more inclined to test the rest of their family at places like Family Tree DNA and MyHeritage who have chromosome browsers and tools that support more serious researchers.

I think a contributing factor is that fewer “serious genealogists” are coming up in the ranks. The perception that all you need to do is enter a couple of generations and click on a few leaves, and you’re “done” misleads people as to the complexity and work involved in genealogical research. Not to mention how many of those hints are inaccurate and require analysis.

Having said that, I view each one of these people who are encouraged for the first time by an ad, even if it is misleading in its simplicity, as a potential candidate. We were all baby genealogists once, and some of us stayed for reasons known only to us. Maybe we have the genealogy gene😊

But yes, I would agree that the majority, by far, of serious genealogists have already tested someplace. What they have not done universally is transferred from 23andMe and Ancestry to the other companies that can help them, such as MyHeritage, FamilyTreeDNA and GEDmatch. If they had, the customer numbers at those companies would be higher. We all need to fish in every pond.

Advertising and Ethnicity

The DNA ads over the last few years have focused almost exclusively on ethnicity – the least reliable aspect of genetic genealogy – but also the “easiest” to understand if a customer takes their ethnicity percentages at face value. And of course, every consumer that purchases a test as a result of one of these ads does exactly that – spits or swabs, mails and opens their results to see what they “are” – full of excited anticipation.

Many people have absolutely no idea there’s more, like cousin matching – and many probably wouldn’t care.

The buying public who purchases due to these ads are clearly not early adopters, and most likely are not genealogists. One can hope that at least a few of them get hooked as a result, or at least enter a minimal tree.

Unfortunately, of the two companies experiencing layoffs, only Ancestry supports trees. Genealogy revolves around trees, pure and simple.

23andMe has literally had years to do so and has refused to natively support trees. Their FamilySearch link is not the same as supporting trees and tree matching. Their attempt at creating a genetic tree is laudable and has potential, but it’s not something that can be translated into a genealogical benefit for most people. I’m guessing that there aren’t any genealogists working for 23andMe, or they aren’t “heard” amid the vervre surrounding medical research.

All told, I’m not surprised that the two companies who are experiencing the layoffs are the two companies whose ads we saw most often focused on ethnicity, especially Ancestry. Who can forget the infamous kilt/leiderhosen ad that Ancestry ran? I still cringe.

Many people who test for ethnicity never sign on again – especially if they are unhappy with the results.

Ancestry and 23andMe spent a lot on ad campaigns, ramped up for the resulting sales, but now the ads are less effective, so not being run as much or at all. Sales are down. Who’s to say which came first, the chicken (fewer ads) or the egg (lower sales.)

This leads us to the next topic, add on sales.

No Repeat Sales

DNA testing, unless you have something else to offer customers is being positioned as a “one and done” sale, meaning that it’s a single purchase with no potential for additional revenue. While that’s offered as a reason for the downturn, it’s not exactly true for DNA test sales.

Ancestry clearly encourages customers to subscribe to their records database by withholding access to some DNA features without a subscription. For Ancestry, DNA is the bait for a yearly repeat sale of a subscription. Genealogists subscribe, of course, but people who aren’t genealogists don’t see the benefit.

Ancestry does not allow transfers into their database, which would provide for additional revenue opportunity. I suspect the reason is twofold. First, they want the direct testing revenue, but perhaps more importantly, in order to sell their customer’s DNA who have agreed to participate in research, or partner with research firms, those customers need to have tested on Ancestry’s custom chip. This holds true for 23andMe as well.

Through the 23andMe financial information in the earlier section, it’s clear that while the consumer only pays a one time fee to test, multiple research companies will pay over and over for access to that compiled consumer information.

Ancestry and 23andMe have the product, your opted-in DNA test that you paid for, and they can sell it over and over again. Hopefully, this revenue stream helps to fund development of genetic genealogical tools.

MyHeritage also provides access to advanced DNA tools by selling a subscription to their records database after a free trial. MyHeritage has integrated their DNA testing with genealogical records to provide their advanced Theories of Family Relativity tool, a huge boon to genealogists.

While Family Tree DNA doesn’t have a genealogical records database like Ancestry and MyHeritage, they provide Y DNA and mitochondrial DNA testing, in addition to the autosomal Family Finder test. If more people tested Y DNA and mitochondrial DNA, more genealogical walls would fall due to the unique inheritance path and the fact that neither Y nor mitochondrial DNA is admixed with DNA from the other parent.

Generally, only genealogists know about and are going to order Y DNA and mtDNA tests, or sponsor others to take them to learn more about their ancestral lines. These tests don’t provide yearly revenue like an ongoing subscription, but at least the fact that Family Tree DNA offers three different tests does provide the potential for at least some additional sales.

Both MyHeritage and FamilyTreeDNA encourage uploads, and neither sell, lease or share your DNA for medical testing. You can find upload instructions, here.

In summary of this section, all of the DNA testing companies do have some sort of additional (potential) revenue stream from DNA testing, so it’s not exactly “one and done.”

Health Testing Products

As for health testing, 23andMe has always offered some level of health information for their customers. Health and research has always been their primary focus. Health and genealogy was originally bundled into one test. Today, DNA ancestry tests with the health option at 23andMe cost more than a genealogy-only test and are two separate products.

MyHeritage also offers a genealogy only DNA test and a genealogy plus health DNA test.

In 2019, both Ancestry and MyHeritage added health testing to their menu as upgrades for existing customers.

In November 2019, FamilyTreeDNA announced an alliance with Tovana for their customers to order a full exome grade medical test and accompanying report. I recently received mine and am still reviewing the results – they are extensive.

It’s clear that all four companies see at least some level of consumer interest in health and traits as a lucrative next step.

Medical Research and DNA Sales

Both Ancestry and 23andMe are pursuing and have invested in relationships with research institutions or Big Pharma. I have concerns with how this is handled. You may not.

I’m supportive of medical research, but I’m concerned that most people have no idea of the magnitude and scope of the contracts between Ancestry and 23andMe with Big Pharma and others, in part, because the details are not public. Customers may also not be aware of exactly what they are opting in to, what it means or where their DNA/DNA results are going.

As a consumer, I want to know where my DNA is, who is using it, and for what purpose. I don’t want my DNA to wind up being used for a nefarious purpose or something I don’t approve of. Think Uighurs in China by way of example. BGI Genetics, headquartered in China but with an Americas division and facilities in Silicon Valley has been a major research institute for years. I want to know what my DNA is being used for, and by whom. The fact that the companies won’t provide their customers with that information makes me makes me immediately wonder why not.

I would like to be able to opt-in for specific studies, not blindly for every use that is profitable to the company involved, all without my knowledge. No blank checks. For example, I opted out of 23andMe research when they patented the technology for designer babies.

Furthermore, I feel that if someone is going to profit from my DNA, it should be me since I paid for the sequencing. At minimum, a person whose DNA is used in these studies should receive some guarantee that they will be provided with any drug in which their DNA is used for development, in particular if their insurance doesn’t pay and they cannot afford the drug.

Drug prices have risen exponentially in the US recently, with many people no longer able to afford their medications. For example, the price of insulin has tripled over the last decade, causing people to ration or cut back on their insulin, if not go without altogether. It would be the greatest of ironies if the very people whose DNA was sold and used to create a drug had no access to it.

Of course, Ancestry and 23andMe are not required to inform consumers of which studies their DNA or DNA results are used for, so we don’t know. Always read all of the terms and conditions, and all links when authorizing anything.

Both companies indicate that your DNA results are anonymized before being shared, but we now know that’s not really possible anymore, because it’s relatively easy to re-identify someone. This is exactly how adoptees identify their biological parents through genetic matches. Dr. Yaniv Erlich reported in the journal Science November 2018 that more than 60% of Europeans could be reidentified through a genealogy database of only 1.28 million individuals.

I think greater transparency and a change in policy favoring the consumer would go a long way to instilling more confidence in the outside research relationships that both Ancestry and 23andMe pursue and maintain. It would probably increase their participation level as well if people could select the research initiatives to which they want to contribute their DNA.

Privacy Concerns

The news has been full of articles about genetic privacy, especially in the months since the Golden State Killer case was solved. That was only April 2018, but it seems like eons ago.

Unfortunately, much of what has been widely reported is inaccurate. For example, no company has ever thrown the data base open for the FBI or anyone to rummage through like a closet full of clothes. However, headlines and commentary like that attract outrage and hundreds of thousands of clicks. In the news and media industry, “it’s all about eyeballs.”

In one case, an article I interviewed for extensively in an educational capacity was written accurately, but the headline was awful. The journalist in question replied that the editors write the headlines, not the reporters.

One instance of this type of issue would be pretty insignificant, but the news in this vein hasn’t abated, always simmering just below the surface waiting for something to fan the flames. Outrage sells.

For the most part, those within the genealogy community at least attempt to sort out what is accurate reporting and what is not, but those people are the ones who have already tested.

People outside the genealogy community just know that they’ve now seen repeated headlines reporting that their genetic privacy either has been, could be or might be breached, and they are suspicious and leery. I would be too. They have no idea what that actually means, what is actually occurring, where, or that they are probably far more at risk on social media sites.

These people are not genealogists, and now they look at ads and think to themselves, “yes, I’d like to do that, but…”

And they never go any further.

People are frightened and simply disconnect from the topic – without testing.

If, as a consumer, you see several articles or posts saying that <fill in car model> is really bad, when you consider a purchase, even if you initially like that model, you’ll remember all of those negative messages. You may never realize that the source was the competition which would cause you to interpret those negative comments in a completely different light.

I think that some of the well-intentioned statements made by companies to reassure their existing and potential customers have actually done more harm than good by reinforcing that there’s a widespread issue. “You’re safe with us” can easily be interpreted as, “there’s something to be afraid of.”

Added to that is the sensitive topic of adoptee and unknown parent searches.

Reunion stories are wonderfully touching, and we all love them, but you seldom see the other side of the coin. Not every story has a happy ending, and many don’t. Not every parent wants to be found for a variety of reasons. If you’re the child and don’t want to find your parents, don’t test, but it doesn’t work the other way around. A parent can often be identified by their relatives’ DNA matches to their child.

While most news coverage reflects positive adoptee reunion outcomes, that’s not universal, and almost every family has a few lurking skeletons. People know that. Some people are fearful of what they might discover about themselves or family members and are correspondingly resistant to DNA testing. Realizing you might discover that your father isn’t your biological father if you DNA test gives people pause. It’s a devastating discovery and some folks decide they’d rather not take that chance, even though they believe it’s not possible.

The genealogical search techniques for identifying unknown parents or close relatives and the technique used by law enforcement to identify unknown people, either bodies or perpetrators is exactly the same. If you are in one of the databases, who you match can provide a very big hint to someone hunting for the identify of an unknown person.

People who are not genealogists, adoptees or parents seeking to find children placed for adoption may be becoming less comfortable with this idea in general.

Of course, the ability for law enforcement to upload kits to GedMatch/Verogen and Family Tree DNA, under specific controlled conditions, has itself been an explosive and divisive topic within and outside of the genealogy community since April 2018.

These law enforcement kits are either cold case remains of victims, known as “Does,” or body fluids from the scenes of violent crimes, such as rape, murder and potentially child abduction and aggravated assault. To date, since the Golden State Killer identification, numerous cases have produced a “solve.” ISOGG, a volunteer organization, maintains a page of known cases solved, here.

GEDmatch encourages people to opt-in for law-enforcement matching, meaning that their kit can be seen as a match to kits uploaded by law enforcement agencies or companies working on behalf of law enforcement agencies. If a customer doesn’t opt-in, their kit can’t be seen as a match to a law enforcement kit.

Family Tree DNA initially opted-out all EU kits from law enforcement matching, due to GDPR, and provides the option for their customers to opt-out of law-enforcement matching.

Neither MyHeritage, Ancestry nor 23andMe cooperate with law enforcment under any circumstances and have stated that they will actively resist all subpoenaes in court.

ISOGG provides a FAQ on Investigative Genetic Genealogy, here.

The two sides of the argument have rather publicly waged war on each other in an ongoing battle to convince people of the merits of their side of the equation, including working with news organizations.

Unfortunately, this topic is akin to arguing over politics. No one changes their mind, and everyone winds up mad.

Notice I’m not linking any articles here, not even my own. I do not want to fan these flames, but I would be remiss if I didn’t mention that the topic of law enforcement usage itself, the on-going public genetic genealogy community war and resulting media coverage together have very probably contributed to the lagging sales. I’d also be remiss if I didn’t mention that while a great division of opinion exists, and many people are opposed, there are also many people who are extremely supportive.

All of this, combined, intentionally or not, has introduced FUD, fear, uncertainty and doubt – a very old disinformation “sales technique.”

In a sense, for consumers, this has been like watching pigs mud-wrestle.

As my dad used to say, “Never mud-wrestle with a pig. The pig enjoys it, you get muddy and the spectators can’t tell the difference.” The spectators in this case vote with their lack of spending and no one is a winner.

DNA Testing Was A FAD

Another theory is that genealogy DNA testing was just a FAD whose time has come and gone. I think the FAD was ethnicity testing, and that chicken has come home to roost.

Both 23andMe and Ancestry clearly geared up for testers attracted by their very successful ads. I was just recently on a cruise, and multiple times I heard people at another table discussing their ethnicity results from some unnamed company. They introduced the topic by saying, “I did my DNA.”

The discussion was almost always the same. Someone said that they thought their ethnicity was pretty accurate, someone else said theirs was awful, and the discussion went from there. Not one time did anyone ever mention a company name, DNA matching or any other functionality. I’m not even sure they understood there are different DNA testing companies.

If I was a novice listening-in, based on that discussion, I would have learned to doubt the accuracy of “doing my DNA.”

If most of the people who purchased ethnicity tests understood in advance that ethnicity testing truly is “just an estimate,” they probably wouldn’t have purchased in the first place. If they understood the limitations and had properly set expectations, perhaps they would not have been as unhappy and disenchanted with their results. I realize that’s not very good marketing, but I think that chicken coming home to roost is a very big part of what we’re seeing now.

The media has played this up too, with stories about how the ethnicity of identical twins doesn’t match. If people bother to read more than the headline, and IF it’s a reasonably accurate article, they’ll come to understand why and how that might occur. If not, what they’ll take away is that DNA testing is wrong and unreliable. So don’t bother.

Furthermore, most people don’t understand that ethnicity testing and cousin matching are two entirely different aspects of a DNA test. The “accuracy” of ethnicity is not related to the accuracy of cousin matching, but once someone questions the credibility of DNA testing – their lack of confidence is universal.

I would agree, the FAD is over – meaning lots of people testing primarily for ethnicity. I think the marketing challenge going forward is to show people that DNA testing can be useful for other things – and to make that easy.

Ethnicity was the low hanging fruit and it’s been picked.

Slowed Growth – Not Dead in the Water

The rate of growth has slowed. This does not by any stretch of the imagination mean that genetic genealogy or DNA testing is dead in the water. DNA fishes for us 365x24x7.

For example, just today, I received a message from 23andMe that 75 new relatives have joined 23andMe. I also received match notifications from Family Tree DNA and MyHeritage.  Hey – calorie-free treats!!!

These new matches are nothing to sneeze at. I remember when I was thrilled over ONE new match.

I have well over 100,000 matches if you combine my matches at the four vendors.

Without advanced tools like triangulation, Phased Family Matching, Theories of Family Relativity, ThruLines, DNAPainter, DNAgedcom and Genetic Affairs, I’d have absolutely no prayer of grouping and processing this number of matches for genealogy.

Even if I received no new matches for the next year, I’d still not be finished analyzing the autosomal matches I already have.

This Too Shall Pass

At least I hope it will.

I think people will still test, but the market has corrected. This level of testing is probably the “new normal.”

Neither Ancestry or 23andMe are spending the big ad dollars – or at least not as big.

In order for DNA testing companies to entice customers into purchasing subscriptions or add-on products, tools need to be developed or enhanced that encourage customers to return to the site over and over. This could come in the form of additional results or functionality calculated on their behalf.

That “on their behalf” point is important. Vendors need to focus on making DNA fun, and productive, not work. New tools, especially in the last year or two, have taken a big step in that direction. Make the customer wonder every day what gift is waiting for him or her that wasn’t there yesterday. Make DNA useful and fun!

I would call this “DNA crack.” 😊

Cooking Up DNA Crack!

In order to assist the vendors, I’ve compiled one general suggestion plus what I would consider to be the “Big 3 Wish List” for each of their DNA products in term of features or improvements that would encourage customers to either use or return to their sites. (You’re welcome.)

I don’t want this to appear negative, so I’ve also included the things I like most about each vendor.

If you have something to add, please feel free to comment in a positive fashion.

Family Tree DNA

I Love: Y and Mitochondrial DNA, Phased Family Matching, and DNA projects

General Suggestion – Fix chronic site loading issues which discourage customers

  • Tree Matching – fix the current issues with trees and implement tree matching for DNA matches
  • Triangulation – including by match group and segment
  • Clustering – some form of genetic networks

MyHeritage

I Love: Theories of Family Relativity, triangulation, wide variety of filters, SmartMatches and Record Matches

General – Clarify confusing subscription options in comparative grid format

  • Triangulation by group and segment
  • View DNA matches by ancestor
  • Improved Ethnicity

Ancestry

I Love: Database size, ThruLines, record and DNA hints (green leaves)

General – Focus on the customers’ needs and repeated requests

  • Accept uploads
  • Chromosome Browser (yes, I know this is a dead horse, but that doesn’t change the need)
  • Triangulation (dead horse’s brother)

23andMe

I Love: Triangulation, Ethnicity quality, ethnicity segments identified, painted and available for download

General – Focus on genealogy tools if you’re going to sell a genealogy test

  • Implement individual customer trees – not Family Search
  • Remove 2000 match limit (which is functionally less after 23andMe hides the people not opted into matching)
  • DNA + Tree Matching

Summary

In summary, we, as consumers need to maintain our composure, assuring others that no one’s hair is on fire and the sky really is not falling. We need to calmly educate as opposed to frighten.

Just the facts.

Other approaches don’t serve us in the end. Frightening people away may “win” the argumentative battle of the day, but we all lose the war if people are no longer willing to test.

This is much like a lifeboat – we all succeed together, or we all lose.

Everybody row!

As genealogists, we need to:

  • Focus on verifying ancestors and solving genealogy challenges
  • Sharing those victories with others, including family members
  • Encourage our relatives to test, and transfer so that their testing investment provides as much benefit as possible
  • Offer to help relatives with the various options on each vendor’s platform
  • Share the joy

People share exciting good news with others, especially on Facebook and social media platforms, and feel personally invested when you share new results with them. Collaboration bonds people.

A positive attitude, balanced perspective and excitement about common ancestors goes a very, very long was in terms of encouraging others.

We have more matches now than ever before, along with more and better tools. Matches are still rolling in, every single day.

New announcements are expected at Rootstech in a couple short weeks.

There’s so much opportunity and work to do.

The sky is not falling. It rained a bit.

The seas may have been stormy, but as a genealogist, the sun is out and a rising tide lifts us all.

Rising tide
