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!!!

RootsTech Connect 2021: Comprehensive DNA Session List

I wondered exactly how many DNA sessions were at RootsTech this year and which ones are the most popular.

Unfortunately, we couldn’t easily view a list of all the sessions, so I made my own. I wanted to be sure to include every session, including Tips and Tricks and vendor sessions that might only be available in their booths. I sifted through every menu and group and just kept finding more and more buried DNA treasures in different places.

I’m sharing this treasure chest with you below. And by the way, this took an entire day, because I’ve listed the YouTube direct link AND how many views each session had amassed today.

Two things first.

RootsTech Sessions

As you know, RootsTech was shooting for TED talk format this year. Roughly 20-minute sessions. When everything was said and done, there were five categories of sessions:

  • Curated sessions are approximately 20-minute style presentations curated by RootsTech meaning that speakers had to submit. People whose sessions were accepted were encouraged to break longer sessions into a series of two or three 20-minute sessions.
  • Vendor booth videos could be loaded to their virtual boots without being curated by RootsTech, but curated videos by their employees could also be loaded in the vendor booths.
  • DNA Learning Center sessions were by invitation and provided by volunteers. They last generally between 10-20 minutes.
  • Tips and Tricks are also produced by volunteers and last from 1 to 15 minutes. They can be sponsored by a company and in some cases, smaller vendors and service providers utilized these to draw attention to their products and services.
  • 1-hour sessions tend to be advanced and not topics could be easily broken apart into a series.

Look at this amazing list of 129 DNA or DNA-related sessions that you can watch for free for the next year. Be sure to bookmark this article so you can refer back easily.

Please note that I started compiling this list for myself and I’ve shortened some of the session names. Then I realized that if I needed this, so do you.

Top 10 Most-Viewed Sessions

I didn’t know whether I should list these sessions by speaker name, or by the most views, so I’m doing a bit of both.

Drum roll please…

The top 10 most viewed sessions as of today are:

Sessions by Speaker

The list below includes the English language sessions by speaker. I apologize for not being able to discern which non-English sessions are about DNA.

Don’t let a smaller number of views discourage you. I’ve watched a few of these already and they are great. I suspect that sessions by more widely-known speakers or ones whose sessions were listed in the prime-real estate areas have more views, but what you need might be waiting just for you in another session. You don’t have to pick and choose and they are all here for you in one place.

Into the Silence

I really want to encourage each and every one of you to work and speak “into the silence.”

What do I mean by that?

When we document something, write something or make something – we do so alone. Just like I’m doing right this minute. I’m writing “into the silence” because I’m writing on faith that people will read and, fingers-crossed, enjoy and utilize my articles.

Often, we write or create with the hope that some particular person, or persons, will appreciate our endeavors. Maybe we created a loving holiday or birthday gift for someone special.

Or, perhaps, our goal is less specific and more intangible.

Think, for example, of a journal.

Each person who writes in a journal generally isn’t journaling for someone else. If so, the “someone else” is a matter of faith – that they *will* exist someday in the future. Journaling is private and the eventual consumer, if they ever exist, is a byproduct of the journaling process, an accident.

In essence, the diarist is writing into the silence because the future is uncertain. Those future readers may not exist. That journal may not survive.

I ask you to ponder how grateful you would be, today, for your great-grandmother’s journal detailing everyday life in her house and garden. Her trips to the market, how and when she did laundry, did it rain or snow, are the tomatoes ripe, who misbehaved at church, along with her thoughts on what was happening in her life and neighborhood.

Or your great-grandfather’s journal about his time separated from his family while in the military serving his country. Did he serve in the Civil War or in WWI, living in a tent-hospital during the 1918 Spanish Flu pandemic? What was that experience like on a personal level?

Maybe letters from your ancestor as they made their way to a new country, seasick the entire time, but filled with hope.

What I’d give for any of those!

Today, maybe you’ve created a book about one of your ancestral lines. Or, maybe you took weeks to sort out, assemble, scan, and organize the photos of your grandparents to share with your siblings.

And perhaps no one even bothered to acknowledge your gift or say thank you. Did they even look at them? Do they care, at all?

That would leave anyone somewhat dejected with hurt feelings.

But if you think about it, what you’re really doing is writing, creating, into the silence.

Not their silence today. No, not that.

But the larger silence of time and space that exists between you and future generations. Without your endeavors, they have no opportunity to glimpse today, or your shared past.

This silence – this silence is what connects you. The umbilical cord that links them to their ancestors through you.

That document, or collage, or scrapbook, or quilt – whatever you created out of love will, hopefully, be passed along. A form of prayer on wings – winging its way to the future with a mission of its own.

The person who will most cherish that gift across time, who will love you for it even though they will never meet you, hasn’t yet been born.

So, I encourage you to continue to honor your ancestors, to tell their stories, to document their lives – and your own.

Yes, someone will care.

Speak into the silence by testing your DNA and making sure it’s available for future genealogists. By researching and documenting your ancestral lines. By ensuring that your work is photographed if it’s a quilt or scrapbook. By placing stories and other writing into repositories where they will be available for those listening future generations even if the current generations seem to be stone-cold deaf.

In my case, my 52 Ancestors stories fall into that category. I’ve written one each week for 320 weeks now, more than six years as hard as that is to believe, and I’m no place near finished. I search for the Y and mitochondrial DNA of each ancestor and document discoveries.

I’m planning to compile the articles, by family line, into books. I will probably use a self-publishing platform such as LuLu.com to assure that their stories are available indefinitely. I’ve linked each ancestor’s story to the proper ancestor on my tree at Ancestry and MyHeritage and I’m in the process at WikiTree as well.

I’ll be donating the books, when created, to various local and regional libraries and genealogy/historical societies, along with both the Allen County Public Library and Family History Library in Salt Lake City.

Remember that activities, pictures, stories, and memories that seem mundane to you today will be someone else’s goldmine happy-dance one day.

It’s not so much the silence we’re speaking into, but acting to honor the past and present for future generations – on faith that someone “out there” will care. We are being that ancestor who we wish would have left something, anything, telling us about their lives and family. How they felt, what they did, what was transpiring around them.

Especially in difficult and trying times, keep on doing what you’re doing and answering that call.

Be encouraged, take heart, and know that your efforts today will cause your name to be spoken with gratitude long after you’ve left this realm.

Genetic Genealogy at 20 Years: Where Have We Been, Where Are We Going and What’s Important?

Not only have we put 2020 in the rear-view mirror, thankfully, we’re at the 20-year, two-decade milestone. The point at which genetics was first added to the toolbox of genealogists.

It seems both like yesterday and forever ago. And yes, I’ve been here the whole time,  as a spectator, researcher, and active participant.

Let’s put this in perspective. On New Year’s Eve, right at midnight, in 2005, I was able to score kit number 50,000 at Family Tree DNA. I remember this because it seemed like such a bizarre thing to be doing at midnight on New Year’s Eve. But hey, we genealogists are what we are.

I knew that momentous kit number which seemed just HUGE at the time was on the threshold of being sold, because I had inadvertently purchased kit 49,997 a few minutes earlier.

Somehow kit 50,000 seemed like such a huge milestone, a landmark – so I quickly bought kits, 49,998, 49,999, and then…would I get it…YES…kit 50,000. Score!

That meant that in the 5 years FamilyTreeDNA had been in business, they had sold on an average of 10,000 kits per year, or 27 kits a day. Today, that’s a rounding error. Then it was momentous!

In reality, the sales were ramping up quickly, because very few kits were sold in 2000, and roughly 20,000 kits had been sold in 2005 alone. I know this because I purchased kit 28,429 during the holiday sale a year earlier.

Of course, I had no idea who I’d test with that momentous New Year’s Eve Y DNA kit, but I assuredly would find someone. A few months later, I embarked on a road trip to visit an elderly family member with that kit in tow. Thank goodness I did, and they agreed and swabbed on the spot, because they are gone today and with them, the story of the Y line and autosomal DNA of their branch.

In the past two decades, almost an entire generation has slipped away, and with them, an entire genealogical library held in their DNA.

Today, more than 40 million people have tested with the four major DNA testing companies, although we don’t know exactly how many.

Lots of people have had more time to focus on genealogy in 2020, so let’s take a look at what’s important? What’s going on and what matters beyond this month or year?

How has this industry changed in the last two decades, and where it is going?

Reflection

This seems like a good point to reflect a bit.

In the beginning – twenty years ago, there were two companies who stuck their toes in the consumer DNA testing water – Oxford Ancestors and Family Tree DNA. About the same time, Sorenson Genomics and GeneTree were also entering that space, although Sorenson was a nonprofit. Today, of those, only FamilyTreeDNA remains, having adapted with the changing times – adding more products, testing, and sophistication.

Bryan Sykes who founded Oxford Ancestors announced in 2018 that he was retiring to live abroad and subsequently passed away in 2020. The website still exists, but the company has announced that they have ceased sales and the database will remain open until Sept 30, 2021.

James Sorenson died in 2008 and the assets of Sorenson Molecular Genealogy Foundation, including the Sorenson database, were sold to Ancestry in 2012. Eventually, Ancestry removed the public database in 2015.

Ancestry dabbled in Y and mtDNA for a while, too, destroying that database in 2014.

Other companies, too many to remember or mention, have come and gone as well. Some of the various company names have been recycled or purchased, but aren’t the same companies today.

In the DNA space, it was keep up, change, die or be sold. Of course, there was the small matter of being able to sell enough DNA kits to make enough money to stay in business at all. DNA processing equipment and a lab are expensive. Not just the equipment, but also the expertise.

The Next Wave

As time moved forward, new players entered the landscape, comprising the “Big 4” testing companies that constitute the ponds where genealogists fish today.

23andMe was the first to introduce autosomal DNA testing and matching. Their goal and focus was always medical genetics, but they recognized the potential in genealogists before anyone else, and we flocked to purchase tests.

Ancestry settled on autosomal only and relies on the size of their database, a large body of genealogy subscribers, and a widespread “feel-good” marketing campaign to sell DNA kits as the gateway to “discover who you are.”

FamilyTreeDNA did and still does offer all 3 kinds of tests. Over the years, they have enhanced both the Y DNA and mitochondrial product offerings significantly and are still known as “the science company.” They are the only company to offer the full range of Y DNA tests, including their flagship Big Y-700, full sequence mitochondrial testing along with matching for both products. Their autosomal product is called Family Finder.

MyHeritage entered the DNA testing space a few years after the others as the dark horse that few expected to be successful – but they fooled everyone. They have acquired companies and partnered along the way which allowed them to add customers (Promethease) and tools (such as AutoCluster by Genetic Affairs), boosting their number of users. Of course, MyHeritage also offers users a records research subscription service that you can try for free.

In summary:

One of the wonderful things that happened was that some vendors began to accept compatible raw DNA autosomal data transfer files from other vendors. Today, FamilyTreeDNA, MyHeritage, and GEDmatch DO accept transfer files, while Ancestry and 23andMe do not.

The transfers and matching are free, but there are either minimal unlock or subscription plans for advanced features.

There are other testing companies, some with niche markets and others not so reputable. For this article, I’m focusing on the primary DNA testing companies that are useful for genealogy and mainstream companion third-party tools that complement and enhance those services.

The Single Biggest Change

As I look back, the single biggest change is that genetic genealogy evolved from the pariah of genealogy where DNA discussion was banned from the (now defunct) Rootsweb lists and summarily deleted for the first few years after introduction. I know, that’s hard to believe today.

Why, you ask?

Reasons varied from “just because” to “DNA is cheating” and then morphed into “because DNA might do terrible things like, maybe, suggest that a person really wasn’t related to an ancestor in a lineage society.”

Bottom line – fear and misunderstanding. Change is exceedingly difficult for humans, and DNA definitely moved the genealogy cheese.

From that awkward beginning, genetic genealogy organically became a “thing,” a specific application of genealogy. There was paper-trail traditional genealogy and then the genetic aspect. Today, for almost everyone, genealogy is “just another tool” in the genealogist’s toolbox, although it does require focused learning, just like any other tool.

DNA isn’t separate anymore, but is now an integral part of the genealogical whole. Having said that, DNA can’t solve all problems or answer all questions, but neither can traditional paper-trail genealogy. Together, each makes the other stronger and solves mysteries that neither can resolve alone.

Synergy.

I fully believe that we have still only scratched the surface of what’s possible.

Inheritance

As we talk about the various types of DNA testing and tools, here’s a quick graphic to remind you of how the different types of DNA are inherited.

  • Y DNA is inherited paternally for males only and informs us of the direct patrilineal (surname) line.
  • Mitochondrial DNA is inherited by everyone from their mothers and informs us of the mother’s matrilineal (mother’s mother’s mother’s) line.
  • Autosomal DNA can be inherited from potentially any ancestor in random but somewhat predictable amounts through both parents. The further back in time, the less identifiable DNA you’ll inherit from any specific ancestor. I wrote about that, here.

What’s Hot and What’s Not

Where should we be focused today and where is this industry going? What tools and articles popped up in 2020 to help further our genealogy addiction? I already published the most popular articles of 2020, here.

This industry started two decades ago with testing a few Y DNA and mitochondrial DNA markers, and we were utterly thrilled at the time. Both tests have advanced significantly and the prices have dropped like a stone. My first mitochondrial DNA test that tested only 400 locations cost more than $800 – back then.

Y DNA and mitochondrial DNA are still critically important to genetic genealogy. Both play unique roles and provide information that cannot be obtained through autosomal DNA testing. Today, relative to Y DNA and mitochondrial DNA, the biggest challenge, ironically, is educating newer genealogists about their potential who have never heard about anything other than autosomal, often ethnicity, testing.

We have to educate in order to overcome the cacophony of “don’t bother because you don’t get as many matches.”

That’s like saying “don’t use the right size wrench because the last one didn’t fit and it’s a bother to reach into the toolbox.” Not to mention that if everyone tested, there would be a lot more matches, but I digress.

If you don’t use the right tool, and all of the tools at your disposal, you’re not going to get the best result possible.

The genealogical proof standard, the gold standard for genealogy research, calls for “a reasonably exhaustive search,” and if you haven’t at least considered if or how Y
DNA
and mitochondrial DNA along with autosomal testing can or might help, then your search is not yet exhaustive.

I attempt to obtain the Y and mitochondrial DNA of every ancestral line. In the article, Search Techniques for Y and Mitochondrial DNA Test Candidates, I described several methodologies to find appropriate testing candidates.

Y DNA – 20 Years and Still Critically Important

Y DNA tracks the Y chromosome for males via the patrilineal (surname) line, providing matching and historical migration information.

We started 20 years ago testing 10 STR markers. Today, we begin at 37 markers, can upgrade to 67 or 111, but the preferred test is the Big Y which provides results for 700+ STR markers plus results from the entire gold standard region of the Y chromosome in order to provide the most refined results. This allows genealogists to use STR markers and SNP results together for various aspects of genealogy.

I created a Y DNA resource page, here, in order to provide a repository for Y DNA information and updates in one place. I would encourage anyone who can to order or upgrade to the Big Y-700 test which provides critical lineage information in addition to and beyond traditional STR testing. Additionally, the Big Y-700 test helps build the Y DNA haplotree which is growing by leaps and bounds.

More new SNPs are found and named EVERY SINGLE DAY today at FamilyTreeDNA than were named in the first several years combined. The 2006 SNP tree listed a grand total of 459 SNPs that defined the Y DNA tree at that time, according to the ISOGG Y DNA SNP tree. Goran Rundfeldt, head of R&D at FamilyTreeDNA posted this today:

2020 was an awful year in so many ways, but it was an unprecedented year for human paternal phylogenetic tree reconstruction. The FTDNA Haplotree or Great Tree of Mankind now includes:

37,534 branches with 12,696 added since 2019 – 51% growth!
defined by
349,097 SNPs with 131,820 added since 2019 – 61% growth!

In just one year, 207,536 SNPs were discovered and assigned FT SNP names. These SNPs will help define new branches and refine existing ones in the future.

The tree is constructed based on high coverage chromosome Y sequences from:
– More than 52,500 Big Y results
– Almost 4,000 NGS results from present-day anonymous men that participated in academic studies

Plus an additional 3,000 ancient DNA results from archaeological remains, of mixed quality and Y chromosome coverage at FamilyTreeDNA.

Wow, just wow.

These three new articles in 2020 will get you started on your Y DNA journey!

Mitochondrial DNA – Matrilineal Line of Humankind is Being Rewritten

The original Oxford Ancestor’s mitochondrial DNA test tested 400 locations. The original Family Tree DNA test tested around 1000 locations. Today, the full sequence mitochondrial DNA test is standard, testing the entire 16,569 locations of the mitochondria.

Mitochondrial DNA tracks your mother’s direct maternal, or matrilineal line. I’ve created a mitochondrial DNA resource page, here that includes easy step-by-step instructions for after you receive your results.

New articles in 2020 included the introduction of The Million Mito Project. 2021 should see the first results – including a paper currently in the works.

The Million Mito Project is rewriting the haplotree of womankind. The current haplotree has expanded substantially since the first handful of haplogroups thanks to thousands upon thousands of testers, but there is so much more information that can be extracted today.

Y and Mitochondrial Resources

If you don’t know of someone in your family to test for Y DNA or mitochondrial DNA for a specific ancestral line, you can always turn to the Y DNA projects at Family Tree DNA by searching here.

The search provides you with a list of projects available for a specific surname along with how many customers with that surname have tested. Looking at the individual Y DNA projects will show the earliest known ancestor of the surname line.

Another resource, WikiTree lists people who have tested for the Y DNA, mitochondrial DNA and autosomal DNA lines of specific ancestors.

On the left side, my maternal great-grandmother’s profile card, and on the right, my paternal great-great-grandfather. You can see that someone has tested for the mitochondrial DNA of Nora (OK, so it’s me) and the Y DNA of John Estes (definitely not me.)

MitoYDNA, a nonprofit volunteer organization created a comparison tool to replace Ysearch and Mitosearch when they bit the dust thanks to GDPR.

MitoYDNA accepts uploads from different sources and allows uploaders to not only match to each other, but to view the STR values for Y DNA and the mutation locations for the HVR1 and HVR2 regions of mitochondrial DNA. Mags Gaulden, one of the founders, explains in her article, What sets mitoYDNA apart from other DNA Databases?.

If you’ve tested at nonstandard companies, not realizing that they didn’t provide matching, or if you’ve tested at a company like Sorenson, Ancestry, and now Oxford Ancestors that is going out of business, uploading your results to mitoYDNA is a way to preserve your investment. PS – I still recommend testing at FamilyTreeDNA in order to receive detailed results and compare in their large database.

CentiMorgans – The Word of Two Decades

The world of autosomal DNA turns on the centimorgan (cM) measure. What is a centimorgan, exactly? I wrote about that unit of measure in the article Concepts – CentiMorgans, SNPs and Pickin’ Crab.

Fortunately, new tools and techniques make using cMs much easier. The Shared cM Project was updated this year, and the results incorporated into a wonderfully easy tool used to determine potential relationships at DNAPainter based on the number of shared centiMorgans.

Match quality and potential relationships are determined by the number of shared cMs, and the chromosome browser is the best tool to use for those comparisons.

Chromosome Browser – Genetics Tool to View Chromosome Matches

Chromosome browsers allow testers to view their matching cMs of DNA with other testers positioned on their own chromosomes.

My two cousins’ DNA where they match me on chromosomes 1-4, is shown above in blue and red at Family Tree DNA. It’s important to know where you match cousins, because if you match multiple cousins on the same segment, from the same side of your family (maternal or paternal), that’s suggestive of a common ancestor, with a few caveats.

Some people feel that a chromosome browser is an advanced tool, but I think it’s simply standard fare – kind of like driving a car. You need to learn how to drive initially, but after that, you don’t even think about it – you just get in and go. Here’s help learning how to drive that chromosome browser.

Triangulation – Science Plus Group DNA Matching Confirms Genealogy

The next logical step after learning to use a chromosome browser is triangulation. If fact, you’re seeing triangulation above, but don’t even realize it.

The purpose of genetic genealogy is to gather evidence to “prove” ancestral connections to either people or specific ancestors. In autosomal DNA, triangulation occurs when:

  • You match at least two other people (not close relatives)
  • On the same reasonably sized segment of DNA (generally 7 cM or greater)
  • And you can assign that segment to a common ancestor

The same two cousins are shown above, with triangulated segments bracketed at MyHeritage. I’ve identified the common ancestor with those cousins that those matching DNA segments descend from.

MyHeritage’s triangulation tool confirms by bracketing that these cousins also match each other on the same segment, which is the definition of triangulation.

I’ve written a lot about triangulation recently.

If you’d prefer a video, I recorded a “Top Tips” Facebook LIVE with MyHeritage.

Why is Ancestry missing from this list of triangulation articles? Ancestry does not offer a chromosome browser or segment information. Therefore, you can’t triangulate at Ancestry. You can, however, transfer your Ancestry DNA raw data file to either FamilyTreeDNA, MyHeritage, or GEDmatch, all three of which offer triangulation.

Step by step download/upload transfer instructions are found in this article:

Clustering Matches and Correlating Trees

Based on what we’ve seen over the past few years, we can no longer depend on the major vendors to provide all of the tools that genealogists want and need.

Of course, I would encourage you to stay with mainstream products being used by a significant number of community power users. As with anything, there is always someone out there that’s less than honorable.

2020 saw a lot of innovation and new tools introduced. Maybe that’s one good thing resulting from people being cooped up at home.

Third-party tools are making a huge difference in the world of genetic genealogy. My favorites are Genetic Affairs, their AutoCluster tool shown above, DNAPainter and DNAGedcom.

These articles should get you started with clustering.

If you like video resources, here’s a MyHeritage Facebook LIVE that I recorded about how to use AutoClusters:

I created a compiled resource article for your convenience, here:

I have not tried a newer tool, YourDNAFamily, that focuses only on 23andMe results although the creator has been a member of the genetic genealogy community for a long time.

Painting DNA Makes Chromosome Browsers and Triangulation Easy

DNAPainter takes the next step, providing a repository for all of your painted segments. In other words, DNAPainter is both a solution and a methodology for mass triangulation across all of your chromosomes.

Here’s a small group of people who match me on the same maternal segment of chromosome 1, including those two cousins in the chromosome browser and triangulation sections, above. We know that this segment descends from Philip Jacob Miller and his wife because we’ve been able to identify that couple as the most distant ancestor intersection in all of our trees.

It’s very helpful that DNAPainter has added the functionality of painting all of the maternal and paternal bucketed matches from Family Tree DNA.

All you need to do is to link your known matches to your tree in the proper place at FamilyTreeDNA, then they do the rest by using those DNA matches to indicate which of the rest of your matches are maternal and paternal. Instructions, here. You can then export the file and use it at DNAPainter to paint all of those matches on the correct maternal or paternal chromosomes.

Here’s an article providing all of the DNAPainter Instructions and Resources.

DNA Matches Plus Trees Enhance Genealogy

Of course, utilizing DNA matching plus finding common ancestors in trees is one of the primary purposes of genetic genealogy – right?

Vendors have linked the steps of matching DNA with matching ancestors in trees.

Genetic Affairs take this a step further. If you don’t have an ancestor in your tree, but your matches have common ancestors with each other, Genetic Affairs assembles those trees to provide you with those hints. Of course, that common ancestor might not be relevant to your genealogy, but it just might be too!

click to enlarge

This tree does not include me, but two of my matches descend from a common ancestor and that common ancestor between them might be a clue as to why I match both of them.

Ethnicity Continues to be Popular – But Is No Shortcut to Genealogy

Ethnicity is always popular. People want to “do their DNA” and find out where they come from. I understand. I really do. Who doesn’t just want an answer?

Of course, it’s not that simple, but that doesn’t mean it’s not disappointing to people who test for that purpose with high expectations. Hopefully, ethnicity will pique their curiosity and encourage engagement.

All four major vendors rolled out updated ethnicity results or related tools in 2020.

The future for ethnicity, I believe, will be held in integrated tools that allow us to use ethnicity results for genealogy, including being able to paint our ethnicity on our chromosomes as well as perform segment matching by ethnicity.

For example, if I carry an African segment on chromosome 1 from my father, and I match one person from my mother’s side and one from my father’s side on that same segment – one or the other of those people should also have that segment identified as African. That information would inform me as to which match is paternal and which is maternal

Not only that, this feature would help immensely tracking ancestors back in time and identifying their origins.

Will we ever get there? I don’t know. I’m not sure ethnicity is or can be accurate enough. We’ll see.

Transition to Digital and Online

Sometimes the future drags us kicking and screaming from the present.

With the imposed isolation of 2020, conferences quickly moved to an online presence. The genealogy community has all pulled together to make this work. The joke is that 2020’s most used phrase is “can you hear me?” I can vouch for that.

Of course while the year 2020 is over, the problem isn’t and is extending at least through the first half of 2021 and possibly longer. Conferences are planned months, up to a year, in advance and they can’t turn on a dime, so don’t even begin to expect in-person conferences until either late in 2021 or more likely, 2022 if all goes well this year.

I expect the future will eventually return to in-person conferences, but not entirely.

Finding ways to be more inclusive allows people who don’t want to or can’t travel or join in-person to participate.

I’ve recorded several sessions this year, mostly for 2021. Trust me, these could be a comedy, mostly of errors😊

I participated in four MyHeritage Facebook LIVE sessions in 2020 along with some other amazing speakers. This is what “live” events look like today!

Screenshot courtesy MyHeritage

A few days ago, I asked MyHeritage for a list of their LIVE sessions in 2020 and was shocked to learn that there were more than 90 in English, all free, and you can watch them anytime. Here’s the MyHeritage list.

By the way, every single one of the speakers is a volunteer, so say a big thank you to the speakers who make this possible, and to MyHeritage for the resources to make this free for everyone. If you’ve ever tried to coordinate anything like this, it’s anything but easy.

Additonally, I’ve created two Webinars this year for Legacy Family Tree Webinars.

Geoff Rasmussen put together the list of their top webinars for 2020, and I was pleased to see that I made the top 10! I’m sure there are MANY MORE you’d be interested in watching. Personally, I’m going to watch #6 yet today! Also, #9 and #22. You can always watch new webinars for free for a few days, and you can subscribe to watch all webinars, here.

The 2021 list of webinar speakers has been announced here, and while I’m not allowed to talk about something really fun that’s upcoming, let’s just say you definitely have something to look forward to in the springtime!

Also, don’t forget to register for RootsTech Connect which is entirely online and completely free, February 25-27, here.

Thank you to Penny Walters for creating this lovely graphic.

There are literally hundreds of speakers providing sessions in many languages for viewers around the world. I’ve heard the stats, but we can’t share them yet. Let me just say that you will be SHOCKED at the magnitude and reach of this conference. I’m talking dumbstruck!

During one of our zoom calls, one of the organizers says it feels like we’re constructing the plane as we’re flying, and I can confirm his observation – but we are getting it done – together! All hands on deck.

I’ll be presenting an advanced session about triangulation as well as a mini-session in the FamilySearch DNA Resource Center about finding your mother’s ancestors. I’ll share more information as it’s released and I can.

Companies and Owners Come & Go

You probably didn’t even notice some of these 2020 changes. Aside from the death of Bryan Sykes (RIP Bryan,) the big news and the even bigger unknown is the acquisition of Ancestry by Blackstone. Recently the CEO, Margo Georgiadis announced that she was stepping down. The Ancestry Board of Directors has announced an external search for a new CEO. All I can say is that very high on the priority list should be someone who IS a genealogist and who understands how DNA applies to genealogy.

Other changes included:

In the future, as genealogy and DNA testing becomes ever more popular and even more of a commodity, company sales and acquisitions will become more commonplace.

Some Companies Reduced Services and Cut Staff

I understand this too, but it’s painful. The layoffs occurred before Covid, so they didn’t result from Covid-related sales reductions. Let’s hope we see renewed investment after the Covid mess is over.

In a move that may or may not be related to an attempt to cut costs, Ancestry removed 6 and 7 cM matches from their users, freeing up processing resources, hardware, and storage requirements and thereby reducing costs.

I’m not going to beat this dead horse, because Ancestry is clearly not going to move on this issue, nor on that of the much-requested chromosome browser.

Later in the year, 23andMe also removed matches and other features, although, to their credit, they have restored at least part of this functionality and have provided ethnicity updates to V3 and V4 kits which wasn’t initially planned.

It’s also worth noting that early in 2020, 23andMe laid off 100 people as sales declined. Since that time, 23andMe has increasingly pushed consumers to pay to retest on their V5 chip.

About the same time, Ancestry also cut their workforce by about 6%, or about 100 people, also citing a slowdown in the consumer testing market. Ancestry also added a health product.

I’m not sure if we’ve reached market saturation or are simply seeing a leveling off. I wrote about that in DNA Testing Sales Decline: Reason and Reasons.

Of course, the pandemic economy where many people are either unemployed or insecure about their future isn’t helping.

The various companies need some product diversity to survive downturns. 23andMe is focused on medical research with partners who pay 23andMe for the DNA data of customers who opt-in, as does Ancestry.

Both Ancestry and MyHeritage provide subscription services for genealogy records.

FamilyTreeDNA is part of a larger company, GenebyGene whose genetics labs do processing for other companies and medical facilities.

A huge thank you to both MyHeritage and FamilyTreeDNA for NOT reducing services to customers in 2020.

Scientific Research Still Critical & Pushes Frontiers

Now that DNA testing has become a commodity, it’s easy to lose track of the fact that DNA testing is still a scientific endeavor that requires research to continue to move forward.

I’m still passionate about research after 20 years – maybe even more so now because there’s so much promise.

Research bleeds over into the consumer marketplace where products are improved and new features created allowing us to better track and understand our ancestors through their DNA that we and our family members inherit.

Here are a few of the research articles I published in 2020. You might notice a theme here – ancient DNA. What we can learn now due to new processing techniques is absolutely amazing. Labs can share files and information, providing the ability to “reprocess” the data, not the DNA itself, as more information and expertise becomes available.

Of course, in addition to this research, the Million Mito Project team is hard at work rewriting the tree of womankind.

If you’d like to participate, all you need to do is to either purchase a full sequence mitochondrial DNA kit at FamilyTreeDNA, or upgrade to the full sequence if you tested at a lower level previously.

Predictions

Predictions are risky business, but let me give it a shot.

Looking back a year, Covid wasn’t on the radar.

Looking back 5 years, neither Genetic Affairs nor DNAPainter were yet on the scene. DNAAdoption had just been formed in 2014 and DNAGedcom which was born out of DNAAdoption didn’t yet exist.

In other words, the most popular tools today didn’t exist yet.

GEDmatch, founded in 2010 by genealogists for genealogists was 5 years old, but was sold in December 2019 to Verogen.

We were begging Ancestry for a chromosome browser, and while we’ve pretty much given up beating them, because the horse is dead and they can sell DNA kits through ads focused elsewhere, that doesn’t mean genealogists still don’t need/want chromosome and segment based tools. Why, you’d think that Ancestry really doesn’t want us to break through those brick walls. That would be very bizarre, because every brick wall that falls reveals two more ancestors that need to be researched and spurs a frantic flurry of midnight searching. If you’re laughing right now, you know exactly what I mean!

Of course, if Ancestry provided a chromosome browser, it would cost development money for no additional revenue and their customer service reps would have to be able to support it. So from Ancestry’s perspective, there’s no good reason to provide us with that tool when they can sell kits without it. (Sigh.)

I’m not surprised by the management shift at Ancestry, and I wouldn’t be surprised to see several big players go public in the next decade, if not the next five years.

As companies increase in value, the number of private individuals who could afford to purchase the company decreases quickly, leaving private corporations as the only potential buyers, or becoming publicly held. Sometimes, that’s a good thing because investment dollars are infused into new product development.

What we desperately need, and I predict will happen one way or another is a marriage of individual tools and functions that exist separately today, with a dash of innovation. We need tools that will move beyond confirming existing ancestors – and will be able to identify ancestors through our DNA – out beyond each and every brick wall.

If a tester’s DNA matches to multiple people in a group descended from a particular previously unknown couple, and the timing and geography fits as well, that provides genealogical researchers with the hint they need to begin excavating the traditional records, looking for a connection.

In fact, this is exactly what happened with mitochondrial DNA – twice now. A match and a great deal of digging by one extremely persistent cousin resulting in identifying potential parents for a brick-wall ancestor. Autosomal DNA then confirmed that my DNA matched with 59 other individuals who descend from that couple through multiple children.

BUT, we couldn’t confirm those ancestors using autosomal DNA UNTIL WE HAD THE NAMES of the couple. DNA has the potential to reveal those names!

I wrote about that in Mitochondrial DNA Bulldozes Brick Wall and will be discussing it further in my RootsTech presentation.

The Challenge

We have most of the individual technology pieces today to get this done. Of course, the combined technological solution would require significant computing resources and processing power – just at the same time that vendors are desperately trying to pare costs to a minimum.

Some vendors simply aren’t interested, as I’ve already noted.

However, the winner, other than us genealogists, of course, will be the vendor who can either devise solutions or partner with others to create the right mix of tools that will combine matching, triangulation, and trees of your matches to each other, even if you don’t’ share a common ancestor.

We need to follow the DNA past the current end of the branch of our tree.

Each triangulated segment has an individual history that will lead not just to known ancestors, but to their unknown ancestors as well. We have reached critical mass in terms of how many people have tested – and more success would encourage more and more people to test.

There is a genetic path over every single brick wall in our genealogy.

Yes, I know that’s a bold statement. It’s not future Jetson’s flying-cars stuff. It’s doable – but it’s a matter of commitment, investment money, and finding a way to recoup that investment.

I don’t think it’s possible for the one-time purchase of a $39-$99 DNA test, especially when it’s not a loss-leader for something else like a records or data subscription (MyHeritage and Ancestry) or a medical research partnership (Ancestry and 23andMe.)

We’re performing these analysis processes manually and piecemeal today. It’s extremely inefficient and labor-intensive – which is why it often fails. People give up. And the process is painful, even when it does succeed.

This process has also been made increasingly difficult when some vendors block tools that help genealogists by downloading match and ancestral tree information. Before Ancestry closed access, I was creating theories based on common ancestors in my matches trees that weren’t in mine – then testing those theories both genetically (clusters, AutoTrees and ThruLines) and also by digging into traditional records to search for the genetic connection.

For example, I’m desperate to identify the parents of my James Lee Clarkson/Claxton, so I sorted my spreadsheet by surname and began evaluating everyone who had a Clarkson/Claxton in their tree in the 1700s in Virginia or North Carolina. But I can’t do that anymore now, either with a third-party tool or directly at Ancestry. Twenty million DNA kits sold for a minimum of $79 equals more than 1.5 billion dollars. Obviously, the issue here is not a lack of funds.

Including Y and mitochondrial DNA resources in our genetic toolbox not only confirms accuracy but also provides additional hints and clues.

Sometimes we start with Y DNA or mitochondrial DNA, and wind up using autosomal and sometimes the reverse. These are not competing products. It’s not either/or – it’s *and*.

Personally, I don’t expect the vendors to provide this game-changing complex functionality for free. I would be glad to pay for a subscription for top-of-the-line innovation and tools. In what other industry do consumers expect to pay for an item once and receive constant life-long innovations and upgrades? That doesn’t happen with software, phones nor with automobiles. I want vendors to be profitable so that they can invest in new tools that leverage the power of computing for genealogists to solve currently unsolvable problems.

Every single end-of-line ancestor in your tree represents a brick wall you need to overcome.

If you compare the cost of books, library visits, courthouse trips, and other research endeavors that often produce exactly nothing, these types of genetic tools would be both a godsend and an incredible value.

That’s it.

That’s the challenge, a gauntlet of sorts.

Who’s going to pick it up?

I can’t answer that question, but I can say that 23andMe can’t do this without supporting extensive trees, and Ancestry has shown absolutely no inclination to support segment data. You can’t achieve this goal without segment information or without trees.

Among the current players, that leaves two DNA testing companies and a few top-notch third parties as candidates – although – as the past has proven, the future is uncertain, fluid, and everchanging.

It will be interesting to see what I’m writing at the end of 2025, or maybe even at the end of 2021.

Stay tuned.

Y DNA Resources and Repository

I’ve created a Y DNA resource page with the information in this article, here, as a permanent location where you can find Y DNA information in one place – including:

  • Step-by-step guides about how to utilize Y DNA for your genealogy
  • Educational articles and links to the latest webinars
  • Articles about the science behind Y DNA
  • Ancient DNA
  • Success stories

Please feel free to share this resource or any of the links to individual articles with friends, genealogy groups, or on social media.

If you haven’t already taken a Y DNA test, and you’re a male (only males have a Y chromosome,) you can order one here. If you also purchase the Family Finder, autosomal test, those results can be used to search together.

What is Y DNA?

Y DNA is passed directly from fathers to their sons, as illustrated by the blue arrow, above. Daughters do not inherit the Y chromosome. The Y chromosome is what makes males, male.

Every son receives a Y chromosome from his father, who received it from his father, and so forth, on up the direct patrilineal line.

Comparatively, mitochondrial DNA, the pink arrow, is received by both sexes of children from the mother through the direct matrilineal line.

Autosomal DNA, the green arrow, is a combination of randomly inherited DNA from many ancestors that is inherited by both sexes of children from both parents. This article explains a bit more.

Y DNA has Unique Properties

The Y chromosome is never admixed with DNA from the mother, so the Y chromosome that the son receives is identical to the father’s Y chromosome except for occasional minor mutations that take place every few generations.

This lack of mixture with the mother’s DNA plus the occasional mutation is what makes the Y chromosome similar enough to match against other men from the same ancestors for hundreds or thousands of years back in time, and different enough to be useful for genealogy. The mutations can be tracked within extended families.

In western cultures, the Y chromosome path of inheritance is usually the same as the surname, which means that the Y chromosome is uniquely positioned to identify the direct biological patrilineal lineage of males.

Two different types of Y DNA tests can be ordered that work together to refine Y DNA results and connect testers to other men with common ancestors.

FamilyTreeDNA provides STR tests with their 37, 67 and 111 marker test panels, and comprehensive STR plus SNP testing with their Big Y-700 test.

click to enlarge

STR markers are used for genealogy matching, while SNP markers work with STR markers to refine genealogy further, plus provide a detailed haplogroup.

Think of a haplogroup as a genetic clan that tells you which genetic family group you belong to – both today and historically, before the advent of surnames.

This article, What is a Haplogroup? explains the basic concept of how haplogroups are determined.

In addition to the Y DNA test itself, Family Tree DNA provides matching to other testers in their database plus a group of comprehensive tools, shown on the dashboard above, to help testers utilize their results to their fullest potential.

You can order or upgrade a Y DNA test, here. If you also purchase the Family Finder, autosomal test, those results can be used to search together.

Step-by-Step – Using Your Y DNA Results

Let’s take a look at all of the features, functions, and tools that are available on your FamilyTreeDNA personal page.

What do those words mean? Here you go!

Come along while I step through evaluating Big Y test results.

Big Y Testing and Results

Why would you want to take a Big Y test and how can it help you?

While the Big Y-500 has been superseded by the Big Y-700 test today, you will still be interested in some of the underlying technology. STR matching still works the same way.

The Big Y-500 provided more than 500 STR markers and the Big Y-700 provides more than 700 – both significantly more than the 111 panel. The only way to receive these additional markers is by purchasing the Big Y test.

I have to tell you – I was skeptical when the Big Y-700 was introduced as the next step above the Big Y-500. I almost didn’t upgrade any kits – but I’m so very glad that I did. I’m not skeptical anymore.

This Y DNA tree rocks. A new visual format with your matches listed on their branches. Take a look!

Educational Articles

I’ve been writing about DNA for years and have selected several articles that you may find useful.

What kinds of information are available if you take a Y DNA test, and how can you use it for genealogy?

What if your father isn’t available to take a DNA test? How can you determine who else to test that will reveal your father’s Y DNA information?

Family Tree DNA shows the difference in the number of mutations between two men as “genetic distance.” Learn what that means and how it’s figured in this article.

Of course, there were changes right after I published the original Genetic Distance article. The only guarantees in life are death, taxes, and that something will change immediately after you publish.

Sometimes when we take DNA tests, or others do, we discover the unexpected. That’s always a possibility. Here’s the story of my brother who wasn’t my biological brother. If you’d like to read more about Dave’s story, type “Dear Dave” into the search box on my blog. Read the articles in publication order, and not without a box of Kleenex.

Often, what surprise matches mean is that you need to dig further.

The words paternal and patrilineal aren’t the same thing. Paternal refers to the paternal half of your family, where patrilineal is the direct father to father line.

Just because you don’t have any surname matches doesn’t necessarily mean it’s because of what you’re thinking.

Short tandem repeats (STRs) and single nucleotide polymorphisms (SNPs) aren’t the same thing and are used differently in genealogy.

Piecing together your ancestor’s Y DNA from descendants.

Haplogroups are something like our pedigree charts.

What does it mean when you have a zero for a marker value?

There’s more than one way to break down that brick wall. Here’s how I figured out which of 4 sons was my ancestor.

Just because you match the right line autosomally doesn’t mean it’s because you descend from the male child you think is your ancestor. Females gave their surnames to children born outside of a legal marriage which can lead to massive confusion. This is absolutely why you need to test the Y DNA of every single ancestral line.

When the direct patrilineal line isn’t the line you’re expecting.

You can now tell by looking at the flags on the haplotree where other people’s ancestral lines on your branch are from. This is especially useful if you’ve taken the Big Y test and can tell you if you’re hunting in the right location.

If you’re just now testing or tested in 2018 or after, you don’t need to read this article unless you’re interested in the improvements to the Big Y test over the years.

2019 was a banner year for discovery. 2020 was even more so, keeping up an amazing pace. I need to write a 2020 update article.

What is a terminal SNP? Hint – it’s not fatal😊

How the TIP calculator works and how to best interpret the results. Note that this tool is due for an update that incorporates more markers and SNP results too.

You can view the location of the Y DNA and mitochondrial DNA ancestors of people whose ethnicity you match.

Tools and Techniques

This free public tree is amazing, showing locations of each haplogroup and totals by haplogroup and country, including downstream branches.

Need to search for and find Y DNA candidates when you don’t know anyone from that line? Here’s how.

Yes, it’s still possible to resolve this issue using autosomal DNA. Non-matching Y DNA isn’t the end of the road, just a fork.

Science Meets Genealogy – Including Ancient DNA

Haplogroup C was an unexpected find in the Americas and reaches into South America.

Haplogroup C is found in several North American tribes.

Haplogroup C is found as far east as Nova Scotia.

Test by test, we made progress.

New testers, new branches. The research continues.

The discovery of haplogroup A00 was truly amazing when it occurred – the base of the phylotree in Africa.

The press release about the discovery of haplogroup A00.

In 2018, a living branch of A00 was discovered in Africa, and in 2020, an ancient DNA branch.

Did you know that haplogroups weren’t always known by their SNP names?

This brought the total of SNPs discovered by Family Tree DNA in mid-2018 to 153,000. I should contact the Research Center to see how many they have named at the end of 2020.

An academic paper split ancient haplogroup D, but then the phylogenetic research team at FamilyTreeDNA split it twice more! This might not sound exciting until you realize this redefines what we know about early man, in Africa and as he emerged from Africa.

Ancient DNA splits haplogroup P after analyzing the remains of two Jehai people from West Malaysia.

For years I doubted Kennewick Man’s DNA would ever be sequenced, but it finally was. Kennewick Man’s mitochondrial DNA haplogroup is X2a and his Y DNA was confirmed to Q-M3 in 2015.

Compare your own DNA to Vikings!

Twenty-seven Icelandic Viking skeletons tell a very interesting story.

Irish ancestors? Check your DNA and see if you match.

Ancestors from Hungary or Italy? Take a look. These remains have matches to people in various places throughout Europe.

The Y DNA story is no place near finished. Dr. Miguel Vilar, former Lead Scientist for National Geographic’s Genographic Project provides additional analysis and adds a theory.

Webinars

Success Stories and Genealogy Discoveries

Almost everyone has their own Y DNA story of discovery. Because the Y DNA follows the surname line, Y DNA testing often helps push those lines back a generation, or two, or four. When STR markers fail to be enough, we can turn to the Big Y-700 test which provides SNP markers down to the very tip of the leaves in the Y DNA tree. Often, but not always, family-defining SNP branches will occur which are much more stable and reliable than STR mutations – although SNPs and STRs should be used together.

Methodologies to find ancestral lines to test, or maybe descendants who have already tested.

DNA testing reveals an unexpected mystery several hundred years old.

When I write each of my “52 Ancestor” stories, I include genetic information, for the ancestor and their descendants, when I can. Jacob was special because, in addition to being able to identify his autosomal DNA, his Y DNA matches the ancient DNA of the Yamnaya people. You can read about his Y DNA story in Jakob Lenz (1748-1821), Vinedresser.

Please feel free to add your success stories in the comments.

What About You?

You never know what you’re going to discover when you test your Y DNA. If you’re a female, you’ll need to find a male that descends from the line you want to test via all males to take the Y DNA test on your behalf. Of course, if you want to test your father’s line, your father, or a brother through that father, or your uncle, your father’s brother, would be good candidates.

What will you be able to discover? Who will the earliest known ancestor with that same surname be among your matches? Will you be able to break down a long-standing brick wall? You’ll never know if you don’t test.

Most Popular Articles of 2020

We all know that 2020 was a year like no other, right? So, what were we reading this year as we spent more time at home?

According to my blog stats, these are the ten most popular articles of 2020.

2020 Rank Blog Article Name Publication Date/Comment
1 Concepts – Calculating Ethnicity Percentages Jan 11, 2017
2 Proving Native American Ancestry Using DNA December 18, 2012
3 Ancestry to Remove DNA Matches Soon – Preservation Strategies with Detailed Instructions Now obsolete article – July 16, 2020
4 Ancestral DNA Percentages – How Much of Them is in You? June 27, 2017
5 Full or Half Siblings? April 3, 2019
6 442 Ancient Viking Skeletons Hold DNA Surprises – Does Your Y or Mitochondrial DNA Match? September 18, 2020
7 Migration Pedigree Chart March 25, 2016
8 DNA Inherited from Grandparents and Great-Grandparents January 14, 2020
9 Optimizing Your Tree at Ancestry for More Hints and DNA ThruLines February 22, 2020
10 Phylogenetic Tree of Novel Coronavirus (hCoV-19) Covid-19 March 12, 2020

Half of these articles were published this year, and half are older.

One article is now obsolete. The Ancestry purge has already happened, so there’s nothing to be done now.

Let’s take a look at the rest and what messages might be held in these popular selections.

Ethnicity

I’m not the least bit surprised by ethnicity being the most popular topic, nor that Concepts – Calculating Ethnicity Percentages is the most popular article. Not only is ethnicity a perennially favorite, but all four major vendors introduced something new this year.

By the way, my perennial caveat still applies – ethnicity is only an estimate😊

While Genetic Groups isn’t actually ethnicity, per se, it’s a layer on top of ethnicity that provides you with locations where your ancestors might have been from and migrated to, based on genetic clusters. Clusters are defined by the locations of ancestors of other people within that genetic cluster.

There’s actually good news at 23andMe. Since this article was published in October, 23andMe has indeed updated the V3 and V4 kits with new ethnicity updates. 23andMe had originally stated they weren’t going to do that, clearly in the hope that people would pay to retest by purchasing the V5 Health + Ancestry test. I’m so glad to see their reversal.

Viewing the older V2 kits, the “updated” date at the bottom of their Ancestry Composition page says they were updated on December 9th or 10th, but I don’t see a difference and they don’t have the “updated” icon like the V3 and V4 kits do.

23andMe made another reversal too and also restored the original matches. They had reduced the number of matches to 1500 for non-Health+Ancestry testers who don’t also subscribe. If you wanted between 1500 and 5000 matches, you had to retest and subscribe for $29 per year. (It’s worth noting that I have over 5000 matches at all of the other vendors.)

To date, 23andMe has restored previous matches and also restored some but not all of the search functionality that they had removed.

What isn’t clear is whether 23andMe will continue to add to this number of matches until the tester reaches the earlier limit of 2000, or whether they have simply restored the previous matches, but the match total will not increase unless you have a subscription.

Consumer feedback works – so thanks to everyone who provided feedback to 23andMe.

Native American Ancestry

The article, Proving Native American Ancestry Using DNA, written 8 years ago, only 5 months after launching this blog, has been in the top 10 every year since I’ve been counting.

I created a Native American reference and resource page too, which you can find here.

I’ll also be publishing some new articles after the first of the year which I promise you’ll find VERY INTERESTING. Something to look forward to.

Understanding Autosomal DNA

2020 has seen more people delving into genealogy + DNA testing which means they need to understand both the results and the concepts underlying their results.

Whooohooo – more people in the pool. Jump on in – the water’s fine!

The articles Ancestral DNA Percentages – How Much of Them is in You? and DNA Inherited from Grandparents and Great-Grandparents both explain how DNA is passed from your ancestors to you.

These are great basic articles if you’re looking to help someone new, and so is First Steps When Your DNA Results are Ready – Sticking Your Toe in the Genealogy Water.

I always look forward to the end of January because there will be lots of matches from holiday gifts being posted. Feel free to forward any of these articles to your new matches. It’s always fun helping new people because you just never know when they might be able to help you.

Surprises

With more and more people testing, more and more people are receiving “surprises” in their results. Need to figure out the difference between full and half-siblings? Then Full or Half Siblings? is the article for you.

Trying to discern other relationships? My favorite tool is the Shared cM Project tool at DNAPainter, here.

Vikings

Who doesn’t want to know if they are related to the ancient Vikings??? You can make that discovery in the article, 442 Ancient Viking Skeletons Hold DNA Surprises – Does Your Y or Mitochondrial DNA Match?. Not only is this just plain fun, but I snuck in a little education too.

Of course, you’ll need to have your Y DNA or mitochondrial DNA results, which you can easily order, here. If you’re unsure and would like to read a short article about the different kinds of DNA and how they can help you, 4 Kinds of DNA for Genetic Genealogy is perfect.

Do you think your DNA isn’t Viking because your ancestors aren’t from Scandinavia? Guess again!

Those Vikings didn’t stay home, and they didn’t restrict their escapades to the British Isles either.

This drawing depicts Viking ships besieging Paris in the year 845. Vikings voyaged into Russia and as far as the Mediterranean.

Have a child studying at home? This might be an interesting topic!

Migration Pedigree Chart

Another just plain fun idea is the Migration Pedigree Chart.

I created this migration pedigree chart in a spreadsheet, but you can also create a pedigree chart in genealogy software with whatever “names” you want. This will also help you figure out the estimated percentages of ethnicity you might reasonably expect.

Another idea for helping kids learn at home and they might accidentally learn about figuring percentages in the process.

ThruLines

ThruLines is the Ancestry tool that assists DNA testers with trees connect the dots to common ancestors with their matches. There are ways to optimize your tree to improve your connections, both in terms of accuracy and the number of Thrulines that form.

Optimizing Your Tree at Ancestry for More Hints and DNA ThruLines provides step by step instructions, which reminds me – I need to write a similar article for MyHeritage’s Theories of Family Relativity. I keep meaning to…

Covid

You know, it wouldn’t be 2020 if I didn’t HAVE to mention that word.

I’m glad to know that people were and hopefully still are educating themselves about Covid. Phylogenetic Tree of Novel Coronavirus (hCoV-19) Covid-19 reflected early information about the novel virus and our first efforts to sequence the DNA. Of course, as expected, just like any other organism, mutations have occurred since then.

Goodness knows, we are all tired of Covid and the resulting safety protocols. Keep on keeping on. We need you on the other side.

Stay home, mask up when you must leave, stay away from other people outside your family that you live with, wash your hands, and get vaccinated as soon as you can.

And until we can all see each other in person again, hopefully, sooner than later, keep on doing genealogy.

Locked in the Library

Be careful what you ask for.

Remember that dream where you’re locked in a library? Remember saying you don’t have enough time for genealogy?

Well, now you are and now you do.

The library is your desk with your computer or maybe your laptop on a picnic table in the yard.

DNA results, matches, and research tools are the books and you’re officially locked in for at least a few more weeks. Free articles like these are your guide.

Hmmm, pandemic isolation doesn’t sound so bad now, does it??

We’ll just rename it “genealogy library lock-in.”

Happy New Year!

What can you discover?

DNA Tidbit #5: What’s Your Goal?

You probably see this all the time on social media:

“I just got my DNA results. Now what?”

No further information is given.

The answer is, “What is your goal?”

Why did they test and what are they hoping to learn?

DNA Tidbit Challenge: Define goals for answering genealogy questions, allowing you to focus your efforts.

Your DNA testing goal depends on a number of factors including:

  • What test you took, meaning Y DNA, mitochondrial or autosomal.
  • Where you tested and the tools they offer.
  • What you’re hoping to achieve. In other words, why did you test in the first place?

For a short article about the difference between Y, mitochondrial, and autosomal DNA, please click here.

For more seasoned genealogists, we may have taken all the tests and answered many questions already, but still, our research needs to be guided by goals.

I regularly check my matches. I still think I may have had a half-sibling that is yet to be located. After I confirm that no, I don’t have any new close matches, I then look at the rest, making notes where appropriate.

Recently, late one night, I thought to myself, “why am I doing this?” Endlessly scrolling through new matches and randomly seeing if I can figure out where they fit or which ancestor we share.

But why?

Originally, I had two broad goals.

  • I wanted to find Y line males in each line and other males from the same supposed line to confirm that indeed the ancestral line is what the paper trail had identified.
  • To confirm that I am indeed descended from the ancestral lines I think I am, meaning no NPEs. As a genealogist, the only thing I’d hate worse than discovering that I’ve been researching the wrong line for all these years is to keep doing so.

Given that I’ve confirmed my connection to ancestors on most lines back several generations now, what are my goals?

Broad and Deep

I’ve realized over the years that goals are both broad and deep.

Broad goals are as I described above, in essence, spanning the entire tree.

My broad goals have changed a bit over time. I’ve located and tested descendants of many Y lines, but I’m still working on a few. I’ve confirmed most of my lineage back several generations by matching the DNA from other children of the same ancestor and using tools like triangulation and DNAPainter to confirm the segment is actually from the ancestral couple I think it is.

I’ve added the goal of breaking down brick walls.

This means that I need to look deep instead of broad.

Deep means that I need to focus on and formulate a plan for each line.

Looking Deep

I’ve identified three specific deep goals and put together a plan with action steps to achieve those goals.

  • Deep Goal #1 – Collecting and Using Y and Mitochondrial DNA

I like to “collect” the Y DNA and mitochondrial DNA results/haplogroups of my ancestors for different reasons. First, I’ve discovered surprises in where their DNA originated. For both Y DNA and mitochondrial DNA, you can identify their continent of origin as well as confirm ancestors or break down brick walls for that one specific line through matches and other tools at Family Tree DNA.

Looking at my tree, my closest ancestor whose Y DNA or mtDNA I don’t have is my great-grandmother, Evaline Miller (1857-1939) who had 4 daughters who all had daughters. You wouldn’t think it would be this difficult to find someone who descends to current through all daughters.

How do I go about achieving this goal? What are some alternatives?

  • Track and ask family members, if possible.
  • Find descendants using MyHeritage, Ancestry and Geneanet (especially in Europe) trees. Bonus – they may also have photos or information that I don’t, especially since this isn’t a distant ancestor.

click to enlarge

Ancestry’s ThruLines shows your matches by ancestor, so long as the connection can be made through trees. Unfortunately, in this case, no one descends correctly for mitochondrial DNA, meaning through all females to the current generation which can be male. BUT, they might have an aunt or uncle who does, so it’s certainly worth making a contact attempt.

  • I can also use WikiTree to see if someone has already tested in her line. Unfortunately, no.

However, I don’t know the profile manager so maybe I should click and see how we might be related. You never know and the answer is no if you don’t ask😊

Deep Goal #2 – Confirming a Specific Ancestor

I want to confirm that a specific ancestor is my ancestor, or as close as I can get.

What do I mean by that?

In the first couple of close generations, using autosomal DNA, we can confirm ancestral lines and parentage. We can confirm our parents and our grandparents, but further back in that, we have to use a combination of our tree and other tools to confirm our paper genealogy.

For example, as we move further back in time, we can’t confirm that one particular son was the father as opposed to his brother. In closer generations, autosomal DNA might help, but not beyond the first couple of generations. Second cousins always match autosomally, but beyond that, not so much.

Using Y DNA, if we can find a suitable candidate, I can confirm that my Estes ancestor actually does descend through the Estes line indicated by my paper trail.

I need to find someone in my line either to test or who has already tested, of course.

click to enlarge

If they do test and share their match information with me, and others from that same line have tested, I can see their earliest known ancestors on their Y DNA match page.

If someone from that line has already tested and has joined a surname project, you can see their results on the public project page if they have authorized public project display.

click to enlarge

This is also one way of determining whether or not your line has already tested, especially if you have no Y DNA matches to the expected surname and ancestor. If others have tested from that ancestor, and you don’t match them, there’s a mystery to be unraveled.

To see if projects exist for your surnames, you can click here and scroll down to the search box, below.

Please note that if someone else in your family takes the Y DNA test, that doesn’t guarantee that you descend from that ancestor too unless that person is a reasonably close relative and you match them autosomally in the expected way.

Confirmation of a specific ancestor requires two things without Y DNA testing:

  • Sharing autosomal matches, and preferably triangulated segments, with others who descend from that ancestor (or ancestral couple) through another child.
  • Eliminating other common ancestors.

Of course, Ancestry’s ThruLines are useful for this purpose as are MyHeritage’s Theories of Family Relativity, but that only works if people have linked their DNA results to a tree.

My favorite tool for ancestor confirmation is DNAPainter where you can paint your segments from FamilyTreeDNA, 23andMe, MyHeritage and GEDmatch, either individually or in bulk. You can’t use Ancestry DNA information for this purpose, but you can transfer your Ancestry DNA file to those other vendors (except 23andMe) for free, and search for matches without retesting. (Step-by-step transfer instructions are found here.)

Here’s an example of a group of my matches from various companies painted on one of my chromosomes at DNAPainter. You can read all about how to use DNAPainter, here.

I identify every match that I can and paint those segments to that ancestor. Ancestors are identified by color that I’ve assigned.

In this case, I have identified several people who descend from ancestors through my paternal grandmother’s side going back four generations. We have a total of 12 descendants of the couple Henry Bolton and Nancy Mann (burgundy), even though initially I can only identify some people back to either my grandparents (mustard color) or my grandmother’s parents (grey) or her grandparents (blue). The fact that several people descend from Henry and Nancy, through multiple children, confirms this segment back to that couple. Of course, we don’t know which person of that couple until we find people matching from upstream ancestors.

What about that purple person? I don’t know how they match to me – meaning through which ancestor based on genealogy. However, I know for sure at least part of that matching segment, the burgundy portion, is through Henry Bolton and Nancy Mann, or their ancestors.

Deep Goal #3 – Breaking Down a Brick Wall

Of course, the nature of your brick wall may vary, but I’ll use the example of not being able to find the parents of an ancestral couple.

In the above example, I mentioned that each segment goes back to a couple. Clearly, in the next generation, that segment either comes from either the father or mother, or parts from both perhaps. In this case, that oldest burgundy segment originated with either Henry Bolton or Nancy Mann.

In other words, in the next generation upstream, that segment can be assigned to another couple.

Even if we don’t know who that couple is, it’s still their DNA and other people may have inherited that very same segment.

What we need to know is if the people who share that segment with us and each other also have people in their trees in common with each other that we don’t have in our trees.

Does that make sense? I’m looking for commonality between other testers in their trees that might allow me to connect back another generation.

That common couple in their trees may be the key to unlocking the next generation.

Caveat – please note that people they have in common that we don’t may also be wives of their ancestors downstream of our common ancestor. Just keep that in mind.

Let’s shift away from that Bolton example and look at another way to identify clusters of people and common ancestors.

In order to identify clusters of people who match me and each other, I utilize Genetic Affairs autocluster, or the AutoCluster features incorporated into MyHeritage or the Tier 1 “Clusters” option at GEDmatch.

Based on the ancestors of people in this red cluster that I CAN identify, I know it’s a Crumley cluster. The wife of my William Crumley (1767/8 – 1837/40) has never been identified. I looked at the trees of the people in this cluster that I don’t know and can’t identify a common ancestor, and I discovered at least two people have a Babb family in their tree.

Babb was a near neighbor to William Crumley’s family, but I’ve also noticed that Babb married into this line downstream another 3 generations in Iowa. These families migrated from Frederick County, VA to Greene County, TN and on, together – so I’ll need to be very careful. However, I can’t help but wonder if my William’s wife was a Babb.

I need to see if any of my other matches have Babb as a common name. Now, I can search for Babb at any of the testing vendors to see what, if anything, I can discover.

Genetic Affairs has a combined AutoCluster and AutoTree/AutoPedigree function that compares and combines the trees of cluster members for you, here.

Goals Summary

Now, it’s your turn.

  • What are your genealogy goals that DNA can assist with?
  • Are those goals broad or deep?
  • What kind of DNA test can answer or help answer those questions?
  • What tools and research techniques fit the quandary at hand?

I suggest that you look at each ancestor, and in particular each end-of-line ancestor thinking about where you can focus to obtain answers and reveal new ancestors.

Happy ancestor hunting!

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!
