Genetic Affairs Reconstructs Trees from Genetic Clusters – Even Without Your Tree or Common Ancestors

Since Genetic Affairs launched in 2018, they’ve added a LOT of new functionality. I initially wrote about their clustering functionality here.

Genetic Affairs AutoClustering, SuperClusters and brand-new AutoTree tree reconstruction are to-die-for features for traditional genealogists. For adoptees or people seeking unknown parentage, they are the best thing since sliced bread, automating tasks previously peformed manually over labor-filled hours, days and months.

Why Genetic Affairs?

Genetic Affairs works with matches from three vendors; Ancestry, FamilyTreeDNA’s Family Finder test and 23andMe.

MyHeritage has integrated a version of Genetic Affairs directly into their product offering on the MyHeritage website so every MyHeritage DNA customer receives clustering functionality, free, through MyHeritage, but not tree reconstruction.

GedMatch has also implemented an autocluster version for Tier 1 users, but GedMatch’s version only works at GedMatch, of course, and does not include the new tree reconstruction feature.

This article pertains to the functionality of the features available directly through Genetic Affairs, including:

  • Clustering your matches visually to identify ancestral lines of people that match you and each other
  • Reports by cluster including common surnames and locations
  • Analysis of trees within each cluster to identify common ancestors
  • Partially reconstructs trees with your known ancestors for each cluster
  • Partially reconstructs trees between your matches even if you don’t have a tree or don’t share the common ancestor

Genetic Affairs provides visualization for linked DNA matches along with critically important clues to help you figure out just how you are related to these people, and these clusters of interrelated people. The Genetic Affairs user manual can be found here.

Analysis

Each time you run Genetic Affairs is called an analysis. Each analysis scans your kit at the selected vendor(s) for all current matches. A few minutes later, you receive a zip file via e-mail with two or three files depending on your selections at Genetic Affairs and the tree availabilty of the vendor:

  • Autocluster file including the visual clusters plus additional information
  • Excel spreadsheet of cluster members and relevant information such as common ancestors and common locations
  • Tree file containing reconstructed trees (23andMe does not support trees, so no trees are available for 23andMe clusters)

Let’s look at each feature. Grab a cup of coffee and head for the computer.

Selecting Analysis Options

I encourage you to experiment. Selecting a wider range of cM (centimorgans) results in a larger file, but may also mean that the analysis times out.

For this report, I’m utilizing my matches at FamilyTreeDNA and selected a cM range of 50 minimum and 250 maximum. I wanted a minimum cluster size of 2 people, meaning 2 in addition to me. This resulted in 249 total matches that met that criteria and 20 people who met the cM criteria but did not have another person with whom to cluster.

I tried a second analysis using 20 cM – 300 cM resulting in a much larger file with 499 people in the cluster group. Currently, 499 is the maximum that will be processed.

Genetic Affairs profiles.png

On the Genetic Affairs Profiles page, I can view all of the profiles I manage. Users can schedule updates where Genetic Affairs automatically scans for matches and produces reports.

By clicking on the Autoscan button, you can schedule automated recurring scans with e-mail notification.

You can scan daily, weekly, monthly or never – whatever interval you select.

You can select both the minimum level of DNA match and the minimum cM. The lowest you can select is 9cM.

You can view any e-mails that have been sent to you by Genetic Affairs. The green envelope means that there’s something in your e-mail box. This answers the question about whether the report was completed and sent. If the report has been sent, but is not in your e-mail, check your spam filter.

Starting the Scan

Back on the Genetic Affairs profiles page, you can initiate an autocluster by clicking on the AutoCluster button where you’ll see the options based on which vendor you’ve selected.

Genetic Affairs autocluster.png

For example, at Ancestry, you can include only people in a particular group or only starred matches.

23andMe includes surname enrichment and triangulated groups options.

Genetic Affairs 23andme autocluster.png

FamilyTreeDNA and Ancestry both include the “AutoTree – identify common ancestors from trees” option. It’s very important that you click this box if you select the “Default AutoCluster” option – or you won’t get the reconstructed trees.

Genetic Affairs default autocluster.png

Of course, you can always run the analysis again.

Genetic Affairs autotree.png

If you click on the “AutoTree AutoCluster” function, the AutoTree box is already checked for you.

Rule Based AutoCluster

The “Rule based AutoCluster” is a dream-come-true for people seeking unknown parents or ancestors in a relatively recent timeframe.

Genetic Affairs Rule Based Autocluster.png

The “Rule based AutoCluster” provides you with options that allow you to do three things:

  • NOT – Exclude your matches with someone else. For example, your mother has tested. You can use the NOT rule to exclude anyone you might match through your mother’s side, providing you with clusters from your father’s side.
  • AND – Combine your results with someone else’s. If you have identified a half-sibling, you can view only clusters of only people who match you AND your half sibling.
  • OR – Combined rules. You can request a cluster of everyone in clusters with person A but not in a cluster with person B. In this case, if you match a number of half siblings, you can include all of their matches, except people who match them through their “other” parent, if that parent has tested.

Genetic Affairs has provided some graphics and examples here, but you may have to be a member of the site to access this page because the options are customized for you. So I’ll include the non-customized information, below. You can click these to open in a separate window and enlarge.

Read the details of how these tools work. They are powerful, so don’t assume you understand without reading carefully.

We have one housekeeping task to complete before we can get to the actual clusters if you are using Family Tree DNA.

I encourage you to utilize Family Tree DNA in addition to other vendors, especially with the introduction of SuperClusters. Family Tree DNA is the only one of the three vendors that supports both trees AND provides detailed segment information for you and your matches.

However, if you’re NOT using Family Tree DNA, skip to the next section titled “Clustering Your Matches.”

Housekeeping at Family Tree DNA – Finding Your Bearer Token

Recently, Family Tree DNA has been updating their trees. Note that during this timeframe, your tree may experience difficulty or slow wait times when loading.

During this conversion process, some trees are not working correctly and some have inadvertently been set to private due to a bug. This won’t stop the tree reconstruction from working for other trees, but after the conversion process is complete and the bugs fixed, there may be more trees available in your matches – so rerun this occasionally.

Check your tree setting to be sure yours is NOT erroneously set to private, otherwise, people can’t see your tree – and you think they can.

This setting can be found by clicking “Account Settings” by flying your mouse over your name in the upper right hand corner of your personal page, then click on “Privacy and Sharing” and scroll down to the bottom to view your selection under “Family Tree Sharing.”

You want to select either “Only Matches” or “All FamilyTreeDNA users,” which is my selection, shown in red. If you select “Only Me,” your matches can’t see your tree. Living people are automatically privatized.

Sometimes there are unintended consequences of vendor updates and upgrades. In particular, vendors don’t test third party software to see if it still works in the same way. Companies like Genetic Affairs which provide invaluable services to the genealogy community test as soon as possible and make whatever changes might be required.

Family Tree DNA has implemented a security token. Users need to retrieve their token separately and enter it into their Genetic Affairs account in order for Genetic Affairs to be able to gather tree information from your tree as well as your matches trees.

Genetic Affairs has documented this step-by-step process, here. The bad news is that you  need to do this every time you run a cluster analysis.

If you use two monitors, put the instructions on one and sign on to your account on the other. Otherwise, print the instructions so you can reference while signed on to your account at Family Tree DNA.

Just so you know, this process looks far more intimidating than it is. Just take a deep breath and follow the step-by-step instructions, below.

This technique only works using Chrome, not in either Edge or Firefox. Use Chrome.

Genetic Affairs FTDNA mytree.png

First, sign on to Family Tree DNA and click on myTree in the upper area. Genetic Affairs provides instructions for both a PC and Mac. I use a PC. You can click to enlarge any of these instructions.

Look for the Search box.

Genetic Affairs step 4 me.png

Type the word “bearer” (without quote marks) and then press Enter. You will see the links at left with the word “bearer” highlighted in yellow. Click on one of those yellow words.

Genetic Affairs step 4 me bearer.png

I clicked on one of those yellow “bearer” links and the box at right in yellow appeared, containing my token. This is what you need to copy.

Genetic Affairs step 4 copy token.png

Copy only the portion of the yellow box that I’ve highlighted above in green, not the words “Authorization: Bearer.” Now all you have to do is paste over at Genetic Affairs.

Genetic Affairs step 5.png

Step 5 from Genetic Affairs.

Genetic Affairs step 5 me.png

I pasted my copied token, above, then clicked on Perform Analysis, the blue button above at right to begin my cluster analysis. It worked wonderfully.

You need to obtain your token every time you want to run an autocluster for accounts at Family Tree DNA. Hopefully Family Tree DNA will do something to eliminate this manual step for Genetic Affairs – but in the mean time, we have this workaround.

I know this seems painful, but it wasn’t and it’s well worthwhile.

Now let’s cluster!

Clustering Your Matches

Genetic Affairs autocluster order.png

At Genetic Affairs, if you initiate clustering by clicking on the AutoCluster button, you’ll need to put a checkmark in the AutoTree function box. If you began by clicking the AutoTree button, the box is automatically checked for you.

A few minutes later, you’ll receive an email with a zipped file. Save this file to someplace on your computer where you can find it, and open the zipped file by clicking.

Genetic Affairs zip file.png

You’ll see the files, above.

Click on the chrome AutoCluster HTML file which will display in your browser.

The first thing you will see is your visual autocluster. It’s so much fun to watch your matches “fly” into place!

Each of the people in this cluster are somehow related to the other people in the custer who have cells of the same color. The people with grey cells are included in two clusters – meaning the one to the right and the one above, both.

Genetic Affairs cluster.png

The names of the matches are listed to the left and above the display.

The legend is to the right.

Genetic Affairs cluster legend.png

I have a total of 41 clusters.

Scrolling down the page, each cluster has additional information, and each column is searchable or selectable, including comments I’ve entered at the vendor.

Genetic Affairs autocluster info

Click to enlarge

Just by looking at these first 3 matches, I know immediately which side of the family and which ancestors are involved with this cluster. I can look at my notes, to the right, which indicate whether I’ve identified our common ancestor. I paint identified matches at DNAPainter which I’ve entered into the notes field at the vendor.

If I’m signed in to my account at the vendor, I can click on my match’s tree link, above, and take a look. Keep in mind that these people can be related to you, and each other, through multiple ancestors.

Genetic Affairs autocluster members.png

You can hover over any person in the grid, above, to view additional information. For each person whose square is grey, indicating membership in (at least) two clusters, you can hover over the grey square and view the members of both clusters. In this case, I’m hovered over the grey square of Brooke and E.H and the black box shows me who is in both people’s clusters.

Note that while a match could be related to you through several ancestors, and hence be in more than 2 clusters, because of the grid nature of clustering, a match can only be displayed in a maximum of 2 different clusters.

Looking at the auto-generated table below, I see the common surnames in cluster 1. Keep in mind that many of these people maybe related to each other through a spouse that you aren’t. Your ancestor’s brother’s children, for example, are also related to each other through your ancestor’s brother’s wife.

Genetic Affairs surnames.png

I know that Vannoy is the common line, but Upton isn’t my ancestor – at least not that I know of. However, a surname with 20 people in a cluster needs to be investigated and evaluated. Do I have any missing wives in this line? Here’s a really great place to start digging.

In this case, it turns out that one of my ancestor’s children married an Upton, and several of his descendants have tested.

Let’s see what other tools we have.

The Ancestor Spreadsheet

Opening the spreadsheet file, I see several rows and columns.

Genetic Affairs common ancestor

Click to enlarge

The common ancestor between the people in the rows is listed at left. The green cells are from my tree.

Two example ancestors are shown above, Mary McDowell and William Harrell, who just happen to have been married to each other.

Scrolling on down, I see rows without green cells.

Genetic Affairs ancestors

Click to enlarge

These people share a common ancestor in their trees, an ancestor that isn’t in my tree. Presumably this is an ancestor I don’t share with them – or one I haven’t identified.

For example, “Bev” and “van” share William Grubb. “Vicki” and “Mark” share Martha Helen Smith. I don’t share either of these ancestors, but Martha Smith married Alvis Winster Bolton, the son of my ancestor – so I know why Martha Helen Smith appears as a common person in the trees of my matches, but not me.

Further down in the same cluster, I notice that one match shares multiple lines in our trees. Therefore, our DNA match could be on either line, or some segments from one line and some from the other.

Scrolling to the bottom of each cluster’s sheet, common locations are provided.

Genetic Affairs locations

Click to enlarge

While the designation of “Tennessee” isn’t terribly exciting, scrolling further down provides a list by county, and that IS exciting, especially if you’re chasing a brick wall. Sometimes a group of ancestors in a location where you’re seeking a female’s family is very suggestive especially when combined with ancestral names and surnames.

Let’s move on to the third group of files, Trees.

The Tree File

Click on the tree file and you’ll see the following.

Genetic Affairs tree file.png

Reconstructed Trees

For each cluster where trees can be reconstructed, you’ll see two files for cluster 1:

  • Ancestors 1
  • Tree 1

Opening the file labeled Ancestors 1, I see the following information for the first ancestor, meaning a common ancestor between the two people listed below that ancestor. You can click to enlarge these images.

Genetic Affairs ancestors by cluster.png

Opening the corresponding Tree 1 file, I see that Genetic Affairs has reconstructed the tree between me and the other testers as best it can based on the provided trees.

Genetic Affairs reconstructed trees.png

Looking at the tree for cluster 3, below, I see this line in cluster 1, above, has been extended because Sarah, the pink match and me all share a common ancestor, Elizabeth Shepherd.

Genetic Affairs reconstructed tree 2.png

Looking at another cluster, below, while I don’t share an ancestor in a tree, three people that I match at a relatively high level do.

Genetic Affairs reconstructed tree no common ancestor.png

As you can see, their common ancestor is Anne Adelaide Chiasson. This is my Acadian line, so our common ancestor or ancestors must be someplace on up that tree, or the result of an undocumented adoption, or a missing ancestor in our trees.

Constructing the trees of your matches to each other, even when you don’t have a common ancestor in your tree, is the best feature of all.

Clustering plus tree reconstruction, especially in combination with the other clues, is the key to breaking through those unyielding  brick walls.

Super AutoClusters

Just as I was getting ready to publish this article, Genetic Affairs released a new feature called Super AutoCluster.

I absolutely love this, because it combines your clusters from multiple vendors – today Ancestry, who does not provide segment information, along with Family Tree DNA, who  provides invaluable segment information.

This combination can be extremely powerful.

To begin a Super AutoCluster, click on that option under an AncestryDNA kit that also has a kit at Family Tree DNA. Both kits need to have a profile at Genetic Affairs.

Genetic Affairs supercluster.png

Next, you’ll see the screen confirming the kits to use. The combined autocluster tool is limited to a total of 500 matches, or 250 at each account. However, that’s more than enough to make some great progress.

Genetic Affairs supercluster setup

Click to enlarge

Note that you’ll need to retrieve and paste your bearer token for Family Tree DNA. Refer to the instructions for the Bearer token section earlier in this article.

Press “Perform Analysis.”

Drum roll please…

Voila, your combined cluster.

Genetic Affairs supercluster cluster

Click to enlarge

In this example, you can see the large peach and purple Ancestry clusters. The green red, brown and pink smaller clusters are Family Tree DNA clusters. The Family Tree DNA clusters have tiny little Fs in their cells. If you click the above graphic to enlarge, you can see the Fs.

However, the grey cells that intersect the two clusters, meaning an Ancestry and a Family Tree DNA cluster, are found in both of those clusters, connecting the clusters for you logically.

If you look closely at the cells labeled here with “common names,” you’ll see “N” in the cells indicating a common names for you to check out within that cluster.

The “Common Ancestors” box shows the people who connect to both clusters.

There are also a number of people that span the green and red Family Tree DNA clusters too.

Genetic Affairs then proceeds to combine the clustered DNA matches and trees for you from both vendors.

Genetic Affairs supercluster tree

Click to enlarge

In addition to the cluster graph and spreadsheet information that now includes combined information, you’ll see a much larger clustered tree.

And again, the best part is that even if you don’t know how you connect to people through trees, their tree and ancestors will be connected, even if you’re absent. You’ll be present in the genetic cluster itself, so you can work the combined tree cluster to see where you might fit in that branch of the family. Because trust me, you do fit – somehow, someplace.

Cost

Genetic Affairs uses a “credit” payment system. Your first 200 credits are free so you can learn. These may last you for weeks or months, depending on how often you run the clusters. If you manage multiple kits, you’ll use credits more quickly, but it’s worth every last dollar. Genetic Affairs is very inexpensive. I manage multiple accounts and I spend around $5 per month. You can read about Genetic Affairs’ payment plans and see sample calculations here.

My recommendation is simply to dive in and use your free credits. By the way, I’m gifting myself with a “credit purchase” for Christmas😊

Genetic Affairs is a wonderful genealogy gift idea for serious genealogists, adoptees or people seeking unknown parents or ancestors in recent generations.

Have You Tested or Transferred With All 4 Vendors?

If you haven’t yet tested at or transferred to each of the main 4 vendors, clustering, reconstructed trees and SuperClusters is yet another reason to do so. Additionally, every close relative’s DNA holds hints that yours doesn’t, so be sure to test them too.

You can purchase kits, below, or read about how to transfer your DNA to vendors who accept uploads – FamilyTreeDNA, MyHeritage and GedMatch, all for free, here.

Enjoy!

First Steps When Your DNA Results are Ready – Sticking Your Toe in the Genealogy Water

First steps helix

Recently someone asked me what the first steps would be for a person who wasn’t terribly familiar with genealogy and had just received their DNA test results.

I wrote an article called DNA Results – First Glances at Ethnicity and Matching which was meant to show new folks what the various vendor interfaces look like. I was hoping this might whet their appetites for more, meaning that the tester might, just might, stick their toe into the genealogy waters😊

I’m hoping this article will help them get hooked! Maybe that’s you!

A Guide

This article can be read in one of two ways – as an overview, or, if you click the links, as a pretty thorough lesson. If you’re new, I strongly suggest reading it as an overview first, then a second time as a deeper dive. Use it as a guide to navigate your results as you get your feet wet.

I’ll be hotlinking to various articles I’ve written on lots of topics, so please take a look at details (eventually) by clicking on those links!

This article is meant as a guideline for what to do, and how to get started with your DNA matching results!

If you’re looking for ethnicity information, check out the First Glances article, plus here and here and here.

Concepts – Calculating Ethnicity Percentages provides you with guidelines for how to estimate your own ethnicity percentages based on your known genealogy and Ethnicity Testing – A Conundrum explains how ethnicity testing is done.

OK, let’s get started. Fun awaits!

The Goal

The goal for using DNA matching in genealogy depends on your interests.

  1. To discover cousins and family members that you don’t know. Some people are interested in finding and meeting relatives who might have known their grandparents or great-grandparents in the hope of discovering new family information or photos they didn’t know existed previously. I’ve been gifted with my great-grandparent’s pictures, so this strategy definitely works!
  2. To confirm ancestors. This approach presumes that you’ve done at least a little genealogy, enough to construct at least a rudimentary tree. Ancestors are “confirmed” when you DNA match multiple other people who descend from the same ancestor through multiple children. I wrote an article, Ancestors: What Constitutes Proof?, discussing how much evidence is enough to actually confirm an ancestor. Confirmation is based on a combination of both genealogical records and DNA matching and it varies depending on the circumstances.
  3. Adoptees and people with unknown parents seeking to discover the identities of those people aren’t initially looking at their own family tree – because they don’t have one yet. The genealogy of others can help them figure out the identity of those mystery people. I wrote about that technique in the article, Identifying Unknown Parents and Individuals Using DNA Matching.

DNAAdoption for Everyone

Educational resources for adoptees and non-adoptees alike can be found at www.dnaadoption.org. DNAAdoption is not just for adoptees and provides first rate education for everyone. They also provide trained and mentored search angels for adoptees who understand the search process along with the intricacies of navigating the emotional minefield of adoption and unknown parent searches.

First Look” classes for each vendor are free for everyone at DNAAdoption and are self-paced, downloadable onto your computer as a pdf file. Intro to DNA, Applied Autosomal DNA and Y DNA Basics classes are nominally priced at between $29 and $49 and I strongly recommend these. DNAAdoption is entirely non-profit, so your class fee or contribution supports their work. Additional resources can be found here and their 12 adoptee search steps here.

Ok, now let’s look at your results.

Matches are the Key

Regardless of your goal, your DNA matches are the key to finding answers, whether you want to make contact with close relatives, prove your more distant ancestors or you’re involved in an adoptee or unknown parent search.

Your DNA matches that of other people because each of you inherited a piece of DNA, called a segment, where many locations are identical. The length of that DNA segment is measured in centiMorgans and those locations are called SNPs, or single nucleotide polymorphisms. You can read about the definition of a centimorgan and how they are used in the article Concepts – CentiMorgans, SNPs and Pickin’Crab.

While the scientific details are great, they aren’t important initially. What is important is to understand that the more closely you match someone, the more closely you are related to them. You share more DNA with close relatives than more distant relatives.

For example, I share exactly half of my mother’s DNA, but only about 25% of each of my grandparents’ DNA. As the relationships move further back in time, I share less and less DNA with other people who descend from those same ancestors.

Informational Tools

Every vendor’s match page looks different, as was illustrated in the First Glances article, but regardless, you are looking for four basic pieces of information:

  • Who you match
  • How much DNA you share with your match
  • Who else you and your match share that DNA with, which suggests that you all share a common ancestor
  • Family trees to reveal the common ancestor between people who match each other

Every vendor has different ways of displaying this information, and not all vendors provide everything. For example, 23andMe does not support trees, although they allow you to link to one elsewhere. Ancestry does not provide a tool called a chromosome browser which allows you to see if you and others match on the same segment of DNA. Ancestry only tells you THAT you match, not HOW you match.

Each vendor has their strengths and shortcomings. As genealogists, we simply need to understand how to utilize the information available.

I’ll be using examples from all 4 major vendors:

Your matches are the most important information and everything else is based on those matches.

Family Tree DNA

I have tested many family members from both sides of my family at Family Tree DNA using the Family Finder autosomal test which makes my matches there incredibly useful because I can see which family members, in addition to me, my matches match.

Family Tree DNA assigns matches to maternal and paternal sides in a unique way, even if your parents haven’t tested, so long as some close relatives have tested. Let’s take a look.

First Steps Family Tree DNA matches.png

Sign on to your account and click to see your matches.

At the top of your Family Finder matches page, you’ll see three groups of things, shown below.

First Steps Family Tree DNA bucketing

Click to enlarge

A row of tools at the top titled Chromosome Browser, In Common With and Not in Common With.

A second row of tabs that include All, Paternal, Maternal and Both. These are the maternal and paternal tabs I mentioned, meaning that I have a total of 4645 matches, 988 of which are from my paternal side and 847 of which are from my maternal side.

Family Tree DNA assigns people to these “buckets” based on matches with third cousins or closer if you have them attached in your tree. This is why it’s critical to have a tree and test close relatives, especially people from earlier generations like aunts, uncles, great-aunts/uncles and their children if they are no longer living.

If you have one or both parents that can test, that’s a wonderful boon because anyone who matches you and one of your parents is automatically bucketed, or phased (scientific term) to that parent’s side of the tree. However, at Family Tree DNA, it’s not required to have a parent test to have some matches assigned to maternal or paternal sides. You just need to test third cousins or closer and attach them to the proper place in your tree.

How does bucketing work?

Maternal or Paternal “Side” Assignment, aka Bucketing

If I match a maternal first cousin, Cheryl, for example, and we both match John Doe on the same segment, John Doe is automatically assigned to my maternal bucket with a little maternal icon placed beside the match.

First Steps Family Tree DNA match info

Click to enlarge

Every vendor provides an estimated or predicted relationship based on a combination of total centiMorgans and the longest contiguous matching segment. The actual “linked relationship” is calculated based on where this person resides in your tree.

The common surnames at far right are a very nice features, but not every tester provides that information. When the testers do include surnames at Family Tree DNA, common surnames are bolded. Other vendors have similar features.

People with trees are shown near their profile picture with a blue pedigree icon. Clicking on the pedigree icon will show you their ancestors. Your matches estimated relationship to you indicates how far back you should expect to share an ancestor.

For example, first cousins share grandparents. Second cousins share great-grandparents. In general, the further back in time your common ancestor, the less DNA you can be expected to share.

You can view relationship information in chart form in my article here or utilize DNAPainter tools, here, to see the various possibilities for the different match levels.

Clicking on the pedigree chart of your match will show you their tree. In my tree, I’ve connected my parents in their proper places, along with Cheryl and Don, mother’s first cousins. (Yes, they’ve given permission for me to utilize their results, so they aren’t always blurred in images.)

Cheryl and Don are my first cousins once removed, meaning my mother is their first cousin and I’m one generation further down the tree. I’m showing the amount of DNA that I share with each of them in red in the format of total DNA shared and longest unbroken segment, taken from the match list. So 382-53 means I share a total of 382 cM and 53 cM is the longest matching block.

First Steps Family Tree DNA tree.png

The Chromosome Browser

Utilizing the chromosome browser, I can see exactly where I match both Don and Cheryl. It’s obvious that I match them on at least some different pieces of my DNA, because the total and longest segment amounts are different.

The reason it’s important to test lots of close relatives is because even siblings inherit different pieces of DNA from their parents, and they don’t pass the same DNA to their offspring either – so in each generation the amount of shared DNA is probably reduced. I say probably because sometimes segments are passed entirely and sometimes not at all, which is how we “lose” our ancestors’ DNA over the generations.

Here’s a matching example utilizing a chromosome browser.

First Steps Family Tree DNA chromosome browser.png

I clicked the checkboxes to the left of both Cheryl and Don on the match page, then the Chromosome Browser button, and now you can see, above, on chromosomes 1-16 where I match Cheryl (blue) and Don (red.)

In this view, both Don and Cheryl are being compared to me, since I’m the one signed in to my account and viewing my DNA matches. Therefore, one of the bars at each chromosome represents Don’s DNA match to me and one represents Cheryl’s. Cheryl is the first person and Don is the second. Person match colors (red and blue) are assigned arbitrarily by the system.

My grandfather and Cheryl/Don’s father, Roscoe, were siblings.

You can see that on some segments, my grandfather and Roscoe inherited the same segment of DNA from their parents, because today, my mother gave me that exact same segment that I share with both Don and Cheryl. Those segments are exactly identical and shown in the black boxes.

The only way for us to share this DNA today is for us to have shared a common ancestor who gave it to two of their children who passed it on to their descendants who DNA tested today.

On other segments, in red boxes, I share part of the same segments of DNA with Cheryl and Don, but someone along the line didn’t inherit all of that segment. For example on chromosome 3, in the red box, you can see that I share more with Cheryl (blue) than Don (red.)

In other cases, I share with either Don or Cheryl, but Don and Cheryl didn’t inherit that same segment of DNA from their father, so I don’t share with both of them. Those are the areas where you see only blue or only red.

On chromosome 12, you can see where it looks like Don’s and Cheryl’s segments butt up against each other. The DNA was clearly divided there. Don received one piece and Cheryl got the other. That’s known as a crossover and you can read about crossovers here, if you’d like.

It’s important to be able to view segment information to be able to see how others match in order to identify which common ancestor that DNA came from.

In Common With

You can use the “In Common With” tool to see who you match in common with any match. My first 6 matches in common with Cheryl are shown below. Note that they are already all bucketed to my maternal side.

First Steps Family Tree DNA in common with

You can click on up to 7 individuals in the check box at left to show them on the chromosome browser at once to see if they match you on common segments.

Each matching segment has its own history and may descend from a different ancestor in your common tree.

If combinations of people do match me on a common segment, because these matches are all on my maternal side, they are triangulated and we know they have to descend from a common ancestor, assuming the segment is large enough. You can read about the concept of triangulation here. Triangulation occurs when 3 or more people (who aren’t extremely closely related like parents or siblings) all match each other on the same reasonably sized segment of DNA.

If you want to download your matches and work through this process in a spreadsheet, that’s an option too.

Size Matters

Small segments can be identical by chance instead of identical by descent.

  • “Identical by chance” means that you accidentally match someone because your DNA on that segment has been combined from both parents and causes it to match another person, making the segment “looks like” it comes from a common ancestor, when it really doesn’t. When DNA is sequenced, both your mother and father’s strands are sequenced, meaning that there’s no way to determine which came from whom. Think of a street with Mom’s side and Dad’s side with identical addresses on the houses on both sides. I wrote about that here.
  • “Identical by descent” means that the DNA is identical because it actually descends from a common ancestor. I discussed that concept in the article, We Match, But Are We Related.

Generally, we only utilize 7cM (centiMorgan) segments and above because at that level, about half of the segments are identical by descent and about half are identical by chance, known as false positives. By the time we move above 15 cM, most, but not all, matches are legitimate. You can read about segment size and accuracy here.

Using “In Common With” and the Matrix

“In Common With” is about who shares DNA. You can select someone you match to see who else you BOTH match. Just because you match two other people doesn’t necessarily mean that it’s on the same segment of DNA. In fact, you could match one person from your mother’s side and the other person from your father’s side.

First Steps match matrix.png

In this example, you match Person B due to ancestor John Doe and Person C due to ancestor Susie Smith. However, Person B also matches person C, but due to ancestor William West that they share and you don’t.

This example shows you THAT they match, but not HOW they match.

The only way to assure that the matches between the three people above are due to the same ancestor is to look at the segments with a chromosome browser and compare all 3 people to each other. Finding 3 people who match on the same segment, from the same side of your tree means that (assuming a reasonably large segment) you share a common ancestor.

Family Tree DNA has a nice matrix function that allows you to see which of your matches also match each other.

First steps matrix link

The important distinction between the matrix and the chromosome browser is that the chromosome browser shows you where your matches match you, but those matches could be from both sides of your tree, unless they are bucketed. The matrix shows you if your matches also match each other, which is a huge clue that they are probably from the same side of your tree.

First Steps Family Tree DNA matrix.png

A matrix match is a significant clue in terms of who descends from which ancestors. For example, I know, based on who Amy matches, and who she doesn’t match, that she descends from the Ferverda side and that Charles, Rex and Maxine descend from ancestors on the Miller side.

Looking in the chromosome browser, I can tell that Cheryl, Don, Amy and I match on some common segments.

Matching multiple people on the same segment that descends from a common ancestor is called triangulation.

Let’s take a look at the MyHeritage triangulation tool.

MyHeritage

Moving now to MyHeritage who provides us with an easy to use triangulation tool, we see the following when clicking on DNA matches on the DNA tab on the toolbar.

First Steps MyHeritage matches

Cousin Cheryl is at MyHeritage too. By clicking on Review DNA Match, the purple button on the right, I can see who else I match in common with Cheryl, plus triangulation.

The list of people Cheryl and I both match is shown below, along with our relationships to each person.

First Steps MyHeritage triangulation

click to enlarge

I’ve selected 2 matches to illustrate.

The first match has a little purple icon to the right which means that Amy triangulates with me and Cheryl.

The second match, Rex, means that while we both match Rex, it’s not on the same segment. I know that without looking further because there is no triangulation button. We both match Rex, but Cheryl matches Rex on a different segment than I do.

Without additional genealogy work, using DNA alone, I can’t say whether or not Cheryl, Rex and I all share a common ancestor. As it turns out, we do. Rex is a known cousin who I tested. However, in an unknown situation, I would have to view the trees of those matches to make that determination.

Triangulation

Clicking on the purple triangulation icon for Amy shows me the segments that all 3 of us, me, Amy and Cheryl share in common as compared to me.

First Steps MyHeritage triangulation chromosome browser.png

Cheryl is red and Amy is yellow. The one segment bracketed with the rounded rectangle is the segment shared by all 3 of us.

Do we have a common ancestor? I know Cheryl and I do, but maybe I don’t know who Amy is. Let’s look at Amy’s tree which is also shown if I scroll down.

First Steps MyHeritage common ancestor.png

Amy didn’t have her tree built out far enough to show our common ancestor, but I immediately recognized the surname Ferveda found in her tree a couple of generations back. Darlene was the daughter of Donald Ferverda who was the son of Hiram Ferverda, my great-grandfather.

Hiram was the father of Cheryl’s father, Roscoe and my grandfather, John Ferverda.

First Steps Hiram Ferverda pedigree.png

Amy is my first cousin twice removed and that segment of DNA that I share with her is from either Hiram Ferverda or his wife Eva Miller.

Now, based on who else Amy matches, I can probably tell whether that segment descends from Hiram or Eva.

Viva triangulation!

Theory of Family Relativity

MyHeritage’s Theory of Family Relativity provides theories to people whose DNA matches regarding their common ancestor if MyHeritage can calculate how the 2 people are potentially related.

MyHeritage uses a combination of tools to make that connection, including:

  • DNA matches
  • Your tree
  • Your match’s tree
  • Other people’s trees at MyHeritage, FamilySearch and Geni if the common ancestor cannot be found in your tree compared against your DNA match’s MyHeritage
  • Documents in the MyHeritage data collection, such as census records, for example.

MyHeritage theory update

To view the Theories, click on the purple “View Theories” banner or “View theory” under the DNA match.

First Steps MyHeritage theory of relativity

The theory is displayed in summary format first.

MyHeritage view full theory

You can click on the “View Full Theory” to see the detail and sources about how MyHeritage calculated various paths. I have up to 5 different theories that utilize separate resources.

MyHeritage review match

click to enlarge

A wonderful aspect of this feature is that MyHeritage shows you exactly the information they utilized and calculates a confidence factor as well.

All theories should be viewed as exactly that and should be evaluated critically for accuracy, taking into consideration sources and documentation.

I wrote about using Theories of Relativity, with instructions, here and here.

I love this tool and find the Theories mostly accurate.

AncestryDNA

Ancestry doesn’t offer a chromosome browser or triangulation but does offer a tree view for people that you match, so long as you have a subscription. In the past, a special “Light” subscription for DNA only was available for approximately $49 per year that provided access to the trees of your DNA matches and other DNA-related features. You could not order online and had to call support, sometimes asking for a supervisor in order to purchase that reduced-cost subscription. The “Light” subscription did not provide access to anything outside of DNA results, meaning documents, etc. I don’t know if this is still available.

After signing on, click on DNA matches on the DNA tab on the toolbar.

You’ll see the following match list.

First Steps Ancestry matches

I’ve tested twice at Ancestry, the second time when they moved to their new chip, so I’m my own highest match. Click on any match name to view more.

First Steps Ancestry shared matches

click to enlarge

You’ll see information about common ancestors if you have some in your trees, plus the amount of shared DNA along with a link to Shared Matches.

I found one of the same cousins at Ancestry whose match we were viewing at MyHeritage, so let’s see what her match to me at Ancestry looks like.

Below are my shared matches with that cousin. The notes to the right are mine, not provided by Ancestry. I make extensive use of the notes fields provided by the vendors.

First Steps Ancestry shared matches with cousin

click to enlarge

On your match list, you can click on any match, then on Shared Matches to see who you both match in common. While Ancestry provides no chromosome browser, you can see the amount of DNA that you share and trees, if any exist.

Let’s look at a tree comparison when a common ancestor can be detected in a tree within the past 7 generations.

First Steps Ancestry view ThruLines.png

What’s missing of course is that I can’t see how we match because there’s no chromosome browser, nor can I see if my matches match each other.

Stitched Trees

What I can see, if I click on “View ThruLines” above or ThruLines on the DNA Summary page on the main DNA tab is all of the people I match who Ancestry THINKS we descend from a common ancestor. This ancestor information isn’t always taken from either person’s tree.

For example, if my match hadn’t included Hiram Ferverda in her tree, Ancestry would use other people’s trees to “stitch them together” such that the tester is shown to be descended from a common ancestor with me. Sometimes these stitched trees are accurate and sometimes they are not, although they have improved since they were first released. I wrote about ThruLines here.

First Steps Ancestry ThruLines tree

click to enlarge

In closer generations, especially if you are looking to connect with cousins, tree matching is a very valuable tool. In the graphic above, you can see all of the cousins who descend from Hiram Ferverda who have tested and DNA match to me. These DNA matches to me either descend from Hiram according to their trees, or Ancestry believes they descend from Hiram based on other people’s trees.

With more distant ancestors, other people’s trees are increasingly likely to be copied with no sources, so take them with a very large grain of salt (perchance the entire salt lick.) I use ThruLines as hints, not gospel, especially the further back in time the common ancestor. I wish they reached back another couple of generations. They are great hints and they end with the 7th generation where my brick walls tend to begin!

23andMe

I haven’t mentioned 23andMe yet in this article. Genealogists do test there, especially adoptees who need to fish in every pond.

23andMe is often the 4th choice of the major 4 vendors for genealogy due to the following challenges:

  • No tree support, other than allowing you to link to a tree at FamilySearch or elsewhere. This means no tree matching.
  • Less than 2000 matches, meaning that every person is limited to a maximum of 2000 matches, minus however many of those 2000 don’t opt-in for genealogical matching. Given that 23andMe’s focus is increasingly health, my number of matches continues to decrease and is currently just over 1500. The good news is that those 1500 are my highest, meaning closest matches. The bad news is the genealogy is not 23andMe’s focus.

If you are an adoptee, a die-hard genealogist or specifically interested in ethnicity, then test at 23andMe. Otherwise all three of the other vendors would be better choices.

However, like the other vendors, 23andMe does have some features that are unique.

Their ethnicity predictions are acknowledged to be excellent. Ethnicity at 23andMe is called Ancestry Composition, and you’ll see that immediately when you sign in to your account.

First Steps 23andMe DNA Relatives.png

Your matches at 23andMe are found under DNA Relatives.

First Steps 23andMe tools

click to enlarge

At left, you’ll find filters and the search box.

Mom’s and Dad’s side filter matches if you’ve tested your parents, but it’s not like the Family Tree DNA bucketing that provides maternal and paternal side bucketing by utilizing through third cousins if your parents aren’t available for testing.

Family names aren’t your family names, but the top family names that match to you. Guess what my highest name is? Smith.

However, Ancestor Birthplaces are quite useful because you can sort by country. For example, my mother’s grandfather Ferverda was born in the Netherlands.

First Steps 23andMe country.png

If I click on Netherlands, I can see my 5 matches with ancestors born in the Netherlands. Of course, this doesn’t mean that I match because of my match’s Dutch ancestors, but it does provide me with a place to look for a common ancestor and I can proceed by seeing who I match in common with those matches. Unfortunately, without trees we’re left to rely on ancestor birthplaces and family surnames, if my matches have entered that information.

One of my Dutch matches also matches my Ferverda cousin. Given that connection, and that the Ferverda family immigrated from Holland in 1868, that’s a starting point.

MyHeritage has a similar features and they are much more prevalent in Europe.

By clicking on my Ferverda cousin, I can view the DNA we share, who we match in common, our common ethnicity and more. I have the option of comparing multiple people in the chromosome browser by clicking on “View DNA Comparison” and then selecting who I wish to compare.

First Steps 23andMe view DNA Comparison.png

By scrolling down instead of clicking on View DNA Comparison, I can view where my Ferverda cousin matches me on my chromosomes, shown below.

First STeps 23andMe chromosome browser.png

23andMe identifies completely identical segments which would be painted in dark purple, the legend at bottom left.

Adoptees love this feature because it would immediately differentiate between half and full siblings. Full siblings share approximately 25% of the exact DNA on both their maternal and paternal strands of DNA, while half siblings only share the DNA from one parent – assuming their parents aren’t closely related. I share no completely identical DNA with my Ferverda cousin, so no segments are painted dark purple.

23andMe and Ancestry Maps Show Where Your Matches Live

Another reason that adoptees and people searching for birth parents or unknown relatives like 23andMe is because of the map function.

After clicking on DNA Relatives, click on the Map function at the top of the page which displays the following map.

First Steps 23andMe map

click to enlarge

This isn’t a map of where your matches ancestors lived, but is where your matches THEMSELVES live. Furthermore, you can zoom in, click on the button and it displays the name of the individual and the city where they live or whatever they entered in the location field.

First Steps 23andMe your location on map.png

I entered a location in my profile and confirmed that the location indeed displays on my match’s maps by signing on to another family member’s account. What I saw is the display above. I’d wager that most testers don’t realize that their home location and photo, if entered, is being displayed to their matches.

I think sharing my ancestors’ locations is a wonderful, helpful, idea, but there is absolutely no reason whatsoever for anyone to know where I live and I feel it’s stalker-creepy and a safety risk.

First Steps 23andMe questions.png

If you enter a location in this field in your profile, it displays on the map.

If you test with 23andMe and you don’t want your location to display on this map to your matches, don’t answer any question that asks you where you call home or anything similar. I never answer any questions at 23andMe. They are known for asking you the same question repeatedly, in multiple locations and ways, until you relent and answer.

Ancestry has a similar map feature and they’ve also begun to ask you questions that are unrelated to genealogy.

Ancestry Map Shows Where Your Matches Live

At Ancestry, when you click to see your DNA matches, look to the right at the map link.

First Steps Ancestry map link.png

By clicking on this link, you can see the locations that people have entered into their profile.

First Steps Ancestry match map.png

As you can see, above, I don’t have a location entered and I am prompted for one. Note that Ancestry does specifically say that this location will be shown to your matches.

You can click on the Ancestry Profile link here, or go to your Personal Profile by click the dropdown under your user name in the upper right hand corner of any page.

This is important because if you DON’T want your location to show, you need to be sure there is nothing entered in the location field.

Under your profile, click “Edit.”

After clicking edit, complete the information you wish to have public or remove the information you do not.

Sometimes Your Answer is a Little More Complicated

This is a First Steps article. Sometimes the answer you seek might be a little more complicated. That’s why there are specialists who deal with this all day, everyday.

What issues might be more complex?

If you’re just starting out, don’t worry about these things for now. Just know when you run into something more complex or that doesn’t make sense, I’m here and so are others. Here’s a link to my Help page.

Getting Started

What do you need to get started?

  • You need to take a DNA test, or more specifically, multiple DNA tests. You can test at Ancestry or 23andMe and transfer your results to both Family Tree DNA and MyHeritage, or you can test directly at all vendors.

Neither Ancestry nor 23andMe accept uploads, meaning other vendors tests, but both MyHeritage and Family Tree DNA accept most file versions. Instructions for how to download and upload your DNA results are found below, by vendor:

Both MyHeritage and Family Tree DNA charge a minimal fee to unlock their advanced features such as chromosome browsers and ethnicity if you upload transfer files, but it’s less costly in both cases than testing directly. However, if you want the MyHeritage DNA plus Health or the Family Tree DNA Y DNA or Mitochondrial DNA tests, you must test directly at those companies for those tests.

  • It’s not required, but it would be in your best interest to build as much of a tree at all three vendors as you can. Every little bit helps.

Your first tree-building step should be to record what your family knows about your grandparents and great-grandparents, aunts and uncles. Here’s what my first step attempt looked like. It’s cringe-worthy now, but everyone has to start someplace. Just do it!

You can build a tree at either Ancestry or MyHeritage and download your tree for uploading at the other vendors. Or, you can build the tree using genealogy software on your computer and upload to all 3 places. I maintain my primary tree on my computer using RootsMagic. There are many options. MyHeritage even provides free tree builder software.

Both Ancestry and MyHeritage offer research/data subscriptions that provide you with hints to historical documents that increase what you know about your ancestors. The MyHeritage subscription can be tried for free. I have full subscriptions to both Ancestry and MyHeritage because they both include documents in their collections that the other does not.

Please be aware that document suggestions are hints and each one needs to be evaluated in the context of what you know and what’s reasonable. For example, if your ancestor was born in 1750, they are not included in the 1900 census, nor do women have children at age 70. People do have exactly the same names. FindAGrave information is entered by humans and is not always accurate. Just sayin’…

Evaluate critically and skeptically.

Ok, Let’s Go!

When your DNA results are ready, sign on to each vendor, look at your matches and use this article to begin to feel your way around. It’s exciting and the promise is immense. Feel free to share the link to this article on social media or with anyone else who might need help.

You are the cumulative product of your ancestors. What better way to get to know them than through their DNA that’s shared between you and your cousins!

2018 – The Year of the Segment

Looking in the rear view mirror, what a year! Some days it’s been hard to catch your breath things have been moving so fast.

What were the major happenings, how did they affect genetic genealogy and what’s coming in 2019?

The SNiPPY Award

First of all, I’m giving an award this year. The SNiPPY.

Yea, I know it’s kinda hokey, but it’s my way of saying a huge thank you to someone in this field who has made a remarkable contribution and that deserves special recognition.

Who will it be this year?

Drum roll…….

The 2018 SNiPPY goes to…

DNAPainter – The 2018 SNiPPY award goes to DNAPainter, without question. Applause, everyone, applause! And congratulations to Jonny Perl, pictured below at Rootstech!

Jonny Perl created this wonderful, visual tool that allows you to paint your matches with people on your chromosomes, assigning the match to specific ancestors.

I’ve written about how to use the tool  with different vendors results and have discovered many different ways to utilize the painted segments. The DNA Painter User Group is here on Facebook. I use DNAPainter EVERY SINGLE DAY to solve a wide variety of challenges.

What else has happened this year? A lot!

Ancient DNA – Academic research seldom reports on Y and mitochondrial DNA today and is firmly focused on sequencing ancient DNA. Ancient genome sequencing has only recently been developed to a state where at least some remains can be successfully sequenced, but it’s going great guns now. Take a look at Jennifer Raff’s article in Forbes that discusses ancient DNA findings in the Americas, Europe, Southeast Asia and perhaps most surprising, a first generation descendant of a Neanderthal and a Denisovan.

From Early human dispersals within the Americas by Moreno-Mayer et al, Science 07 Dec 2018

Inroads were made into deeper understanding of human migration in the Americas as well in the paper Early human dispersals within the Americas by Moreno-Mayer et al.

I look for 2019 and on into the future to hold many more revelations thanks to ancient DNA sequencing as well as using those sequences to assist in understanding the migration patterns of ancient people that eventually became us.

Barbara Rae-Venter and the Golden State Killer Case

Using techniques that adoptees use to identify their close relatives and eventually, their parents, Barbara Rae-Venter assisted law enforcement with identifying the man, Joseph DeAngelo, accused (not yet convicted) of being the Golden State Killer (GSK).

A very large congratulations to Barbara, a retired patent attorney who is also a genealogist. Nature recognized Ms. Rae-Venter as one of 2018’s 10 People Who Mattered in Science.

DNA in the News

DNA is also represented on the 2018 Nature list by Viviane Slon, a palaeogeneticist who discovered an ancient half Neanderthal, half Denisovan individual and sequenced their DNA and He JianKui, a Chinese scientist who claims to have created a gene-edited baby which has sparked widespread controversy. As of the end of the year, He Jiankui’s research activities have been suspended and he is reportedly sequestered in his apartment, under guard, although the details are far from clear.

In 2013, 23andMe patented the technology for designer babies and I removed my kit from their research program. I was concerned at the time that this technology knife could cut two ways, both for good, eliminating fatal disease-causing mutations and also for ethically questionable practices, such as eugenics. I was told at the time that my fears were unfounded, because that “couldn’t be done.” Well, 5 years later, here we are. I expect the debate about the ethics and eventual regulation of gene-editing will rage globally for years to come.

Elizabeth Warren’s DNA was also in the news when she took a DNA test in response to political challenges. I wrote about what those results meant scientifically, here. This topic became highly volatile and politicized, with everyone seeming to have a very strongly held opinion. Regardless of where you fall on that opinion spectrum (and no, please do not post political comments as they will not be approved), the topic is likely to surface again in 2019 due to the fact that Elizabeth Warren has just today announced her intention to run for President. The good news is that DNA testing will likely be discussed, sparking curiosity in some people, perhaps encouraging them to test. The bad news is that some of the discussion may be unpleasant at best, and incorrect click-bait at worst. We’ve already had a rather unpleasant sampling of this.

Law Enforcement and Genetic Genealogy

The Golden State Killer case sparked widespread controversy about using GedMatch and potentially other genetic genealogy data bases to assist in catching people who have committed violent crimes, such as rape and murder.

GedMatch, the database used for the GSK case has made it very clear in their terms and conditions that DNA matches may be used for both adoptees seeking their families and for other uses, such as law enforcement seeking matches to DNA sequenced during a criminal investigation. Since April 2018, more than 15 cold case investigations have been solved using the same technique and results at GedMatch. Initially some people removed their DNA from GedMatch, but it appears that the overwhelming sentiment, based on uploads, is that people either aren’t concerned or welcome the opportunity for their DNA matches to assist apprehending criminals.

Parabon Nanolabs in May established a genetic genealogy division headed by CeCe Moore who has worked in the adoptee community for the past several years. The division specializes in DNA testing forensic samples and then assisting law enforcement with the associated genetic genealogy.

Currently, GedMatch is the only vendor supporting the use of forensic sample matching. Neither 23anMe nor Ancestry allow uploaded data, and MyHeritage and Family Tree DNA’s terms of service currently preclude this type of use.

MyHeritage

Wow talk about coming onto the DNA world stage with a boom.

MyHeritage went from a somewhat wobbly DNA start about 2 years ago to rolling out a chromosome browser at the end of January and adding important features such as SmartMatching which matches your DNA and your family trees. Add triangulation to this mixture, along with record matching, and you’re got a #1 winning combination.

It was Gilad Japhet, the MyHeritage CEO who at Rootstech who christened 2018 “The Year of the Segment,” and I do believe he was right. Additionally, he announced that MyHeritage partnered with the adoption community by offering 15,000 free kits to adoptees.

In November, MyHeritage hosted MyHeritage LIVE, their first user conference in Oslo, Norway which focused on both their genealogical records offerings as well as DNA. This was a resounding success and I hope MyHeritage will continue to sponsor conferences and invest in DNA. You can test your DNA at MyHeritage or upload your results from other vendors (instructions here). You can follow my journey and the conference in Olso here, here, here, here and here.

GDPR

GDPR caused a lot of misery, and I’m glad the implementation is behind us, but the the ripples will be affecting everyone for years to come.

GDPR, the European Data Protection Regulation which went into effect on May 25,  2018 has been a mixed and confusing bag for genetic genealogy. I think the concept of users being in charge and understanding what is happened with their data, and in this case, their data plus their DNA, is absolutely sound. The requirements however, were created without any consideration to this industry – which is small by comparison to the Googles and Facebooks of the world. However, the Googles and Facebooks of the world along with many larger vendors seem to have skated, at least somewhat.

Other companies shut their doors or restricted their offerings in other ways, such as World Families Network and Oxford Ancestors. Vendors such as Ancestry and Family Tree DNA had to make unpopular changes in how their users interface with their software – in essence making genetic genealogy more difficult without any corresponding positive return. The potential fines, 20 million plus Euro for any company holding data for EU residents made it unwise to ignore the mandates.

In the genetic genealogy space, the shuttering of both YSearch and MitoSearch was heartbreaking, because that was the only location where you could actually compare Y STR and mitochondrial HVR1/2 results. Not everyone uploaded their results, and the sites had not been updated in a number of years, but the closure due to GDPR was still a community loss.

Today, mitoydna.org, a nonprofit comprised of genetic genealogists, is making strides in replacing that lost functionality, plus, hopefully more.

On to more positive events.

Family Tree DNA

In April, Family Tree DNA announced a new version of the Big Y test, the Big Y-500 in which at least 389 additional STR markers are included with the Big Y test, for free. If you’re lucky, you’ll receive between 389 and 439 new markers, depending on how many STR markers above 111 have quality reads. All customers are guaranteed a minimum of 500 STR markers in total. Matching was implemented in December.

These additional STR markers allow genealogists to assemble additional line marker mutations to more granularly identify specific male lineages. In other words, maybe I can finally figure out a line marker mutation that will differentiate my ancestor’s line from other sons of my founding ancestor😊

In June, Family Tree DNA announced that they had named more than 100,000 SNPs which means many haplogroup additions to the Y tree. Then, in September, Family Tree DNA published their Y haplotree, with locations, publicly for all to reference.

I was very pleased to see this development, because Family Tree DNA clearly has the largest Y database in the industry, by far, and now everyone can reap the benefits.

In October, Family Tree DNA published their mitochondrial tree publicly as well, with corresponding haplogroup locations. It’s nice that Family Tree DNA continues to be the science company.

You can test your Y DNA, mitochondrial or autosomal (Family Finder) at Family Tree DNA. They are the only vendor offering full Y and mitochondrial services complete with matching.

2018 Conferences

Of course, there are always the national conferences we’re familiar with, but more and more, online conferences are becoming available, as well as some sessions from the more traditional conferences.

I attended Rootstech in Salt Lake City in February (brrrr), which was lots of fun because I got to meet and visit with so many people including Mags Gaulden, above, who is a WikiTree volunteer and writes at Grandma’s Genes, but as a relatively expensive conference to attend, Rootstech was pretty miserable. Rootstech has reportedly made changes and I hope it’s much better for attendees in 2019. My attendance is very doubtful, although I vacillate back and forth.

On the other hand, the MyHeritage LIVE conference was amazing with both livestreamed and recorded sessions which are now available free here along with many others at Legacy Family Tree Webinars.

Family Tree University held a Virtual DNA Conference in June and those sessions, along with others, are available for subscribers to view.

The Virtual Genealogical Association was formed for those who find it difficult or impossible to participate in local associations. They too are focused on education via webinars.

Genetic Genealogy Ireland continues to provide their yearly conference sessions both livestreamed and recorded for free. These aren’t just for people with Irish genealogy. Everyone can benefit and I enjoy them immensely.

Bottom line, you can sit at home and educate yourself now. Technology is wonderful!

2019 Conferences

In 2019, I’ll be speaking at the National Genealogical Society Family History Conference, Journey of Discovery, in St. Charles, providing the Special Thursday Session titled “DNA: King Arthur’s Mighty Genetic Lightsaber” about how to use DNA to break through brick walls. I’ll also see attendees at Saturday lunch when I’ll be providing a fun session titled “Twists and Turns in the Genetic Road.” This is going to be a great conference with a wonderful lineup of speakers. Hope to see you there.

There may be more speaking engagements at conferences on my 2019 schedule, so stay tuned!

The Leeds Method

In September, Dana Leeds publicized The Leeds Method, another way of grouping your matches that clusters matches in a way that indicates your four grandparents.

I combine the Leeds method with DNAPainter. Great job Dana!

Genetic Affairs

In December, Genetic Affairs introduced an inexpensive subscription reporting and visual clustering methodology, but you can try it for free.

I love this grouping tool. I have already found connections I didn’t know existed previously. I suggest joining the Genetic Affairs User Group on Facebook.

DNAGedcom.com

I wrote an article in January about how to use the DNAGedcom.com client to download the trees of all of your matches and sort to find specific surnames or locations of their ancestors.

However, in December, DNAGedcom.com added another feature with their new DNAGedcom client just released that downloads your match information from all vendors, compiles it and then forms clusters. They have worked with Dana Leeds on this, so it’s a combination of the various methodologies discussed above. I have not worked with the new tool yet, as it has just been released, but Kitty Cooper has and writes about it here.  If you are interested in this approach, I would suggest joining the Facebook DNAGedcom User Group.

Rootsfinder

I have not had a chance to work with Rootsfinder beyond the very basics, but Rootsfinder provides genetic network displays for people that you match, as well as triangulated views. Genetic networks visualizations are great ways to discern patterns. The tool creates match or triangulation groups automatically for you.

Training videos are available at the website and you can join the Rootsfinder DNA Tools group at Facebook.

Chips and Imputation

Illumina, the chip maker that provides the DNA chips that most vendors use to test changed from the OmniExpress to the GSA chip during the past year. Older chips have been available, but won’t be forever.

The newer GSA chip is only partially compatible with the OmniExpress chip, providing limited overlap between the older and the new results. This has forced the vendors to use imputation to equalize the playing field between the chips, so to speak.

This has also caused a significant hardship for GedMatch who is now in the position of trying to match reasonably between many different chips that sometimes overlap minimally. GedMatch introduced Genesis as a sandbox beta version previously, but are now in the process of combining regular GedMatch and Genesis into one. Yes, there are problems and matching challenges. Patience is the key word as the various vendors and GedMatch adapt and improve their required migration to imputation.

DNA Central

In June Blaine Bettinger announced DNACentral, an online monthly or yearly subscription site as well as a monthly newsletter that covers news in the genetic genealogy industry.

Many educators in the industry have created seminars for DNACentral. I just finished recording “Getting the Most out of Y DNA” for Blaine.

Even though I work in this industry, I still subscribed – initially to show support for Blaine, thinking I might not get much out of the newsletter. I’m pleased to say that I was wrong. I enjoy the newsletter and will be watching sessions in the Course Library and the Monthly Webinars soon.

If you or someone you know is looking for “how to” videos for each vendor, DNACentral offers “Now What” courses for Ancestry, MyHeritage, 23andMe, Family Tree DNA and Living DNA in addition to topic specific sessions like the X chromosome, for example.

Social Media

2018 has seen a huge jump in social media usage which is both bad and good. The good news is that many new people are engaged. The bad news is that people often given faulty advice and for new people, it’s very difficult (nigh on impossible) to tell who is credible and who isn’t. I created a Help page for just this reason.

You can help with this issue by recommending subscribing to these three blogs, not just reading an article, to newbies or people seeking answers.

Always feel free to post links to my articles on any social media platform. Share, retweet, whatever it takes to get the words out!

The general genetic genealogy social media group I would recommend if I were to select only one would be Genetic Genealogy Tips and Techniques. It’s quite large but well-managed and remains positive.

I’m a member of many additional groups, several of which are vendor or interest specific.

Genetic Snakeoil

Now the bad news. Everyone had noticed the popularity of DNA testing – including shady characters.

Be careful, very VERY careful who you purchase products from and where you upload your DNA data.

If something is free, and you’re not within a well-known community, then YOU ARE THE PRODUCT. If it sounds too good to be true, it probably is. If it sounds shady or questionable, it’s probably that and more, or less.

If reputable people and vendors tell you that no, they really can’t determine your Native American tribe, for example, no other vendor can either. Just yesterday, a cousin sent me a link to a “tribe” in Canada that will, “for $50, we find one of your aboriginal ancestors and the nation stamps it.” On their list of aboriginal people we find one of my ancestors who, based on mitochondrial DNA tests, is clearly NOT aboriginal. Snake oil comes in lots of flavors with snake oil salesmen looking to prey on other people’s desires.

When considering DNA testing or transfers, make sure you fully understand the terms and conditions, where your DNA is going, who is doing what with it, and your recourse. Yes, read every single word of those terms and conditions. For more about legalities, check out Judy Russell’s blog.

Recommended Vendors

All those DNA tests look yummy-good, but in terms of vendors, I heartily recommend staying within the known credible vendors, as follows (in alphabetical order).

For genetic genealogy for ethnicity AND matching:

  • 23andMe
  • Ancestry
  • Family Tree DNA
  • GedMatch (not a vendor because they don’t test DNA, but a reputable third party)
  • MyHeritage

You can read about Which DNA Test is Best here although I need to update this article to reflect the 2018 additions by MyHeritage.

Understand that both 23andMe and Ancestry will sell your DNA if you consent and if you consent, you will not know who is using your DNA, where, or for what purposes. Neither Family Tree DNA, GedMatch, MyHeritage, Genographic Project, Insitome, Promethease nor LivingDNA sell your DNA.

The next group of vendors offers ethnicity without matching:

  • Genographic Project by National Geographic Society
  • Insitome
  • LivingDNA (currently working on matching, but not released yet)

Health (as a consumer, meaning you receive the results)

Medical (as a contributor, meaning you are contributing your DNA for research)

  • 23andMe
  • Ancestry
  • DNA.Land (not a testing vendor, doesn’t test DNA)

There are a few other niche vendors known for specific things within the genetic genealogy community, many of whom are mentioned in this article, but other than known vendors, buyer beware. If you don’t see them listed or discussed on my blog, there’s probably a reason.

What’s Coming in 2019

Just like we couldn’t have foreseen much of what happened in 2018, we don’t have access to a 2019 crystal ball, but it looks like 2019 is taking off like a rocket. We do know about a few things to look for:

  • MyHeritage is waiting to see if envelope and stamp DNA extractions are successful so that they can be added to their database.
  • www.totheletterDNA.com is extracting (attempting to) and processing DNA from stamps and envelopes for several people in the community. Hopefully they will be successful.
  • LivingDNA has been working on matching since before I met with their representative in October of 2017 in Dublin. They are now in Beta testing for a few individuals, but they have also just changed their DNA processing chip – so how that will affect things and how soon they will have matching ready to roll out the door is unknown.
  • Ancestry did a 2018 ethnicity update, integrating ethnicity more tightly with Genetic Communities, offered genetic traits and made some minor improvements this year, along with adding one questionable feature – showing your matches the location where you live as recorded in your profile. (23andMe subsequently added the same feature.) Ancestry recently said that they are promising exciting new tools for 2019, but somehow I doubt that the chromosome browser that’s been on my Christmas list for years will be forthcoming. Fingers crossed for something new and really useful. In the mean time, we can download our DNA results and upload to MyHeritage, Family Tree DNA and GedMatch for segment matching, as well as utilize Ancestry’s internal matching tools. DNA+tree matching, those green leaf shared ancestor hints, is still their strongest feature.
  • The Family Tree DNA Conference for Project Administrators will be held March 22-24 in Houston this year, and I’m hopeful that they will have new tools and announcements at that event. I’m looking forward to seeing many old friends in Houston in March.

Here’s what I know for sure about 2019 – it’s going to be an amazing year. We as a community and also as individual genealogists will be making incredible discoveries and moving the ball forward. I can hardly wait to see what quandaries I’ve solved a year from now.

What mysteries do you want to unravel?

I’d like to offer a big thank you to everyone who made 2018 wonderful and a big toast to finding lots of new ancestors and breaking down those brick walls in 2019.

Happy New Year!!!

When DNA Leads You Astray

I’m currently going through what I refer to as “the great purge.”

This occurs when you can’t stand the accumulated piles and boxes of “stuff” and the file drawers are full, so you set about throwing away and giving away. (Yes, I know you just cringed. Me too.)

The great news is that I’ve run across so much old (as in decades old) genealogy from when I first began this journey. I used to make lists of questions and a research “to do” list. I was much more organized then, but there were also fewer “squirrel moments” available online to distract me with “look here, no, over here, no, wait….”

Most of those questions on my old genealogy research lists have (thankfully) since been answered, slowly, one tiny piece of evidence at a time. Believe me, that feeling is very rewarding and while on a daily basis we may not think we’re making much progress; in the big picture – we’re slaying that dragon!

However, genealogy is also fraught with landmines. If I had NOT found the documentation before the days of DNA testing, I could easily have been led astray.

“What?”, you ask, but “DNA doesn’t lie.” No, it doesn’t, but it will sure let you kid yourself about some things.

DNA is a joker and has no problem allowing you to fool yourself and by virtue of that, others as well.

Joke’s On Me

Decades ago, Aunt Margaret told me that her grandmother’s mother was “a Rosenbalm from up on the Lee County (VA) border.”

Now, at that time, I had absolutely NO reason to doubt what she said. After all, it’s her grandmother, Margaret Claxton/Clarkson who she knew personally, who didn’t pass away until my aunt was in her teens. Plenty close enough to know who Margaret Claxton’s mother was. Right?

DNA Astray Rosenbalm

Erroneous pedigree chart. Rebecca Rosenbalm is NOT the mother of Elizabeth Claxton/Clarkson.

I filled Rebecca Rosenbalm’s name into the appropriate space on my pedigree chart, was happy and smugly smiling like a Cheshire cat, right up until I accidentally discovered that the information was just plain wrong.

Uh oh….

Time Rolls On

As records became increasingly available, both in transcribed fashion and online, Hancock County, TN death certificates eventually could be obtained, one way or another. Being a dutiful genealogist, I collected all relevant documents for my ancestors, contentedly filing them in the “well that’s done” category – that is right up until Margaret Clarkson Bolton’s death certificate stopped me dead in my tracks.

margaret clarkson bolton death

Oops

Margaret’s mother wasn’t listed as Rebecca Rosenbalm, nor Rebecca anyone. She was listed as Betsy Speaks. Or was it Spears? In our family, Betsy is short for Elizabeth.

Who the heck was Elizabeth Speaks, or Spears. This was one fine monkey wrench!

A trip to Hancock County, Tennessee was in order.

I dug through dusty deed and court records, sifted through the archives in basements and the old jail building where I just KNEW my ancestors had inhabited cells at one time or another.

Yes, my ancestor’s records really were in jail!

Records revealed that the woman in question was Elizabeth Speaks, not Spears, although the Spears family did live in the area and had “married in” to many local families. Nothing is ever simple and our ancestors do have a perverse sense of humor.

Elizabeth Speak(s) was the daughter of Charles Speak, and the Speak family lived a few miles across the border into Lee County, Virginia. This high mountain land borders two states and three counties, so records are scattered among them – not to mention two fires in the Hancock County courthouse make research challenging.

Why?

I asked my Aunt Margaret who was still living at the time about this apparent discrepancy and she told me that the Rosenbalms “up in Rose Hill, Virginia” told her that her grandmother, Margaret Claxton/Clarkson was kin to them, so Margaret had assumed (there’s that word again) that Margaret Claxton’s mother was their Rebecca Rosenbalm.

Wrong!

The Kernel of Truth

Like so many family stories, there is a kernel of truth, surrounded by a multitude errors. Distilling the grain of truth is the challenge of course.

Margaret Claxton’s mother was Elizabeth (Betsy) Speak and her father was Charles Speak. Charles Speak’s sister, Rebecca married William Henderson Rosenbalm in 1854, had 4 children and died in February 1859. So there indeed was a woman named Rebecca (Speaks) Rosenbalm who had died young and wasn’t well known.

Rebecca’s sister Frances “Fanny” Speak also married that same William Henderson Rosenbalm in November 1859, a few months after Rebecca had died. Fannie also had 4 children, one of which was also named Rebecca Rosenbalm. Do you see a trend here?

So, indeed there were 7 living Rosenbalm children who were first cousins to Elizabeth Speak who married Samuel Claxton and lived a dozen miles away, over the mountains and across the Powell River. Now a dozen miles might not sound like much today, but in the mountains during horse and wagon days – 10 miles wasn’t trivial and required a multi-day commitment for a visit. In other words, the next generation of the family knew of their cousins but didn’t know them well.

The following generation included my Aunt Margaret who was told by those cousins that she was related to them through the Rosenbalm family. While, that was true for the Rosenbalm cousins, it was not true for Aunt Margaret who was related to the Rosenbalms through their common Speak ancestor.

Here’s what the family tree really looks like, only showing the lines under discussion.

DNA astray correct pedigree

You can see why Aunt Margaret might not know specifics. She was actually several generations removed from the common ancestor. She knew THAT they were related, but not HOW they were related and there were several Rebecca’s in several branches of the family.

Why Does This Matter?

You’ve probably guessed by now that someplace in here, there’s a moral to this story, so here it is!

You may have already surmised that I have autosomal DNA matches to cousins through the Rosenbalm/Speaks line.

DNA astray pedigree match

This is one example, but there are more, some being double cousins meaning two of Nicholas Speak’s 11 children’s descendants have intermarried. Life is a lot more complex in those hills and hollers than people think – and unraveling the relationships, both paper and genetic (which are sometimes two different things) is challenging.

DNA astray chromosome 10.png

I match this fourth cousin once removed (4C1R) on a healthy 18 cM segment on chromosome 10.

Wrong Conclusions

Now, think back to where I was originally in my research. I knew that Margaret Claxton/Clarkson was my aunt’s grandmother. I knew nothing at all about the Speak family and had never heard that surname.

Had I ONLY been looking to confirm the Rosenbalm connection, I certainly would have confirmed that I’m related to the Rosenbalm family descendants with this match. Except the conclusion that I descend from a Rosenbalm ancestor would have been WRONG. What we share are the Speak ancestors.

So really, the DNA didn’t lie, but unless I dissected what the DNA match was really telling me carefully and methodically with NO PRECONCEIVED NOTIONS, I would have “confirmed” erroneous information. Or, at least I would have thought that I confirmed it.

I would actually have been doing something worse meaning convincing myself of “facts” that weren’t accurate, which means I would have then been spreading around those cancerous bad trees. Guaranteed, I do NOT want to be that person.

Foolers

I can tell you here and now that I have found several matches that were foolers because I share multiple ancestors with a person that I match, even if those multiple ancestors aren’t known to either or both of us. Every single DNA segment has its own unique history. I match one individual on two segments, one segment through my mom and one segment through my dad. Fortunately, we’ve identified both ancestors now, but imaging my initial surprise and confusion, especially given that my parents don’t share any common ancestors, communities or locations.

We have to evaluate all of the evidence to confirm that the conclusion being drawn in accurate.

DNA astray painting

One of the sanity checks I use, in addition to triangulation, is to paint my matches with known ancestors on my chromosomes using DNAPainter. Here’s the match to my cousin, and it overlaps with other people who share the same ancestor couple. Several matches are obscured behind the black box. If I discover someone that I supposedly match from a different ancestor couple sharing this segment of my father’s DNA, that’s a red neon flashing sign that something is wrong and I need to figure out what and why.

Ignoring this problem and hoping it will go away doesn’t work. I’ve tried😊

Three possible things can be wrong:

  1. The segment is identical by chance, not by descent. With a segment of 18 cM, that’s extremely unlikely. Triangulation with other people on this same segment on the same parent’s side should eliminate most false matches over 7cM. The larger the match, the more likely it is NOT identical by chance, meaning that it IS identical by descent or genealogically relevant.
  2. The segment is accurately matched but the genealogy is confused – such as my Rosenbalm example. This can happen with multiple ancestors, or descent from the same family but through an unknown connection. Looking for other connections to this family and sorting through matches’ trees often provides hints that resolve this situation. In my case, I might have noticed that I matched other people who descended from Nicholas Speak, which would not have been the case had I descended through the Rosenbalm family.
  3. The third scenarios is that the genealogy is plain flat out wrong. Yea, I know this one hurts. Get the saw ready.

The Devil in the Details

Always evaluate your matches in light of what you don’t know, not in order to confirm what you think you know. Play the devil’s advocate – all the time. After all, the devil really is in the details.

AutoClustering by Genetic Affairs

The company Genetic Affairs launched a few weeks ago with an offer to regularly visit your vendor accounts at Family Tree DNA, Ancestry and 23andMe, and compile a spreadsheet of your matches, download it, and send it to you in an e-mail. They then update your match list at regular intervals of your choosing.

I didn’t take advantage of this, mostly because Ancestry doesn’t provide me with segment information and while 23andMe and Family Tree DNA both do, I maintain a master spreadsheet that the new matches wouldn’t integrate with. Granted, I could sort by match date and add only the new ones to my master spreadsheet, but it was never a priority. That was yesterday.

AutoClustering

That changed this week. Genetic Affairs introduced a new AutoClustering tool that provides users with clustered matches. I’m salivating and couldn’t get signed up quickly enough.

Please note that I’ve cropped the names for this article – the Genetic Affairs display shows you the entire name.

In short, each tiny square node represents a three-way match, between you and both of the people in the intersection of the grid. This does NOT mean they are triangulated, but it does mean there’s a really good chance they would triangulate. Think of this as the Family Tree DNA matrix on steroids and automated.

This tool allows me by using my mother’s test as well to actually triangulate my matches. If they are on my mother’s side of the tree, match me and mother both, and are in the match matrix, they must triangulate on my mother’s side of my tree if they both match me on the same segment.

With this information, I can check the chromosome browser, comparing my chromosomes to those other two individuals in the matrix to see if we share a common segment – or I can simply sort the spreadsheet provided with the AutoCluster results. Suddenly that delivery service is extremely convenient!

No, this service is not free, but it’s quite reasonable. I’m going to step through the process. Note that at times, the website seemed to be unresponsive especially when moving from one step to another. Refreshing the page remedied the problem.

Account Setup

Go to www.geneticaffairs.com. Click on Register to set up your account, which is very easy.

After registering, move to step 2, “Add website.”

Add websites where you have accounts. All of your own profiles plus the other people’s that you manage at both Ancestry and 23andMe are included when you register that site in your profile.

You’ll need your signon information and password for each site.

At Family Tree DNA, you’ll need to add a new website for each account since every account has its own kit number and password.

I added my own account and my mother’s account since mother’s DNA is every bit as relevant to my genealogy as my own, AND, I only received half of her DNA which means she will have many matches that I don’t.

When you’re finished adding accounts, click on “Websites and Profiles” at the top to open the website tab of your choosing and click on the blue circular arrows AutoCluster link. You are telling the system to go out and gather your matches from the vendor and then cluster your matches together, generating an AutoCluster graphic file.

There are several more advanced options, but I’m going to run initially with Approach A, the default level. This will exclude my closest matches. Your closest matches will fall into multiple cluster groups, and the software is not set up to accommodate that – so they will wind up as a grey nonclustered square. That’s not all bad, but you’ll want to experiment to see which parameters are best for you.

If you have half-siblings, you may want to work with alternate settings because that half-sibling is important in terms of phasing your matches to maternal or paternal sides.

Asking me if “I’m sure” always causes me to really sit back and think about what I’ve done. Like, do I want to delete my account. In this case, it’s “overworry” because the system is just asking if you want to spend 25 credits, which is less than a dollar and probably less than a quarter. Right now, you’re using your free initial credits anyway.

The first time you set up an account, Genetic Affairs signs in to your account to assure that your login information is accurate.

I selected my profile and my mother’s profile at Family Tree DNA, plus one profile each at 23andMe and Ancestry. I have two profiles at both 23andMe (V3 and V4) and Ancestry (V1 and V2).

When making my selections, I wasn’t clear about the meaning of “minimum DNA match” initially, but it means fourth cousin and closer, NOT fourth and more distant.

My recommendation until you get the hang of things is to use the first default option, at least initially, then experiment.

Welcome

While I was busy ordering AutoClusters, Genetic Affairs was sending me a welcome e-mail.

Hello Roberta Estes,

Thank you for joining Genetic Affairs! We hope you will enjoy our services.

We have a manual available as well as a frequently asked questions section that both provide background information how to use our website.

You currently have 200 credits which can be supplemented using single payments and/or monthly subscriptions. Check out our prices page for more information concerning our rates.

Please let us know if anything is unclear, we can be reached using the contact form.

The great news is that everyone begins with 200 free credits which may last you for quite some time.  Or not. Consider them introductory crack from your new pusher.

Options

Genetic affairs will sign on your account at either Ancestry, 23andMe or Family Tree DNA, or all 3, periodically and provide you with match information about your new matches at each website. You select the interval when you configure your account. After each update, you can order a new AutoCluster if you wish.

Each update, and each AutoCluster request has a cost in points, sold as credits, associated with the service.

To purchase credits after you use your initial 200, you will need to enter your credit card information in the Settings Page, which is found in the dropdown (down arrow) right beside your profile photo.

You can select from and enroll in several plans.

Prices which varies by how often you want updates to be performed and for how many accounts. To see the various service offerings and cost, click here.

Here’s an example calculation for weekly updates:

This is exactly what I need, so it looks like this service will cost me $2.16 per month, plus any Autoclustering which is 25 credits each time I AutoCluster. Therefore, I’ll add another 100 credits for a total of $3.16 per month.

It looks like the $5 per month package will do for me. But don’t worry about that right now, because you’re enjoying your free crack, um, er, credits.

Ok, the e-mail with my results has just arrived after the longest 10 minutes on earth, so let’s take a look!

The Results E-mail

In a few minutes (or longer) after you order, an e-mail with the autoclustering results will arrive. Check your spam filter. Some of my e-mails were there, and some reports simply had to be reordered. One report never arrived after being ordered 3 times.

The e-mail when it arrives states the following:

Hello Roberta Estes,

For profile Roberta Estes: An AutoCluster analysis has been performed (access it through the attached HTML file).

As requested, cM thresholds of 250 cM and 50 cM were used. A total number of 176 matches were identified that were used for a AutoCluster analysis. There should be two CSV files attached to this email and if enough matches can be clustered, an additional HTML file. The first CSV file contains all matches that were identified. The second CSV file contains a spreadsheet version of the AutoCluster analysis. The HTML file will contain a visual representation of the AutoCluster analysis if enough matches were present for the clustering analysis. Please note that some files might be displayed incorrectly when directly opened from this email. Instead, save them to your local drive and open the files from there.

Attached I found 3 files:

  • Matches list
  • Autocluster grid csv file
  • Autocluster html file that shows the cluster itself

The Match Spreadsheet

The first thing that will arrive in your e-mail is a spreadsheet of your matches for the account you configured and ordered an AutoCluster for.

In the e-mail, your top 20 matches are listed, which initially confused me, because I wondered if that means they are not in the spreadsheet. They are.

At 23andMe, I initially selected 5th cousins and closer, which was the most distant match option provided. I had a total of 1233 matches.

23andMe caps your account at 2000 (unless you have communicated with people who are further than 2000 away, in which case they remain on your list), but you can’t modify the Genetic Affairs profile to include any people more distant than 5th cousins

Note that the 23andMe download shows you information about your match, but NOT the actual matching segment information☹

At Ancestry, I selected 4th cousin and closer and I received a total of 2698 matches. I could select “distant cousin” which would result in additional matches being downloaded and a different autoclustering diagram. I may experiment with this with my V2 account and compare them side by side.

This Ancestry information provides an important clue for me, because the matches I work with are generally only my Shared Ancestor Hints matches. If the Viewed field equals false, this tells  me immediately that I didn’t have a shared ancestor hint – but now because of the clustering, I know where they might fit.

At Family Tree DNA, I selected 4th cousin, but I could have selected 5th cousins. I have a total of 1500 matches.

This report does include the segment information (Yay!) and my only wish here would be to merge the two downloads available at Family Tree DNA, meaning the segment information and the match information. I’d like to know which of these are assigned to maternal or paternal buckets, or both.

AutoClustering

The Autocluster csv file is interesting in that it shows who matches whom. It’s the raw data used to construct the colored grid.

My matches are numbered in their column. For example, person M.B. is person 1. Every person that matches person 1 is noted at left with a 1 in that column.  Look at the second person under the Name column, C. W., who matches person 1 (M.B.), 2 (C.W.), 3 (T.F.), 4 (purple) and 5 (A.D.).

All of these people are in the same cluster, number 3, which you’ll see below.

The AutoCluster Graph

Finally, we get to the meat of the matter, the cluster graph.

Caveat – I experienced a significant amount of difficulty with both my account and my graph. If your graph does not display correctly, save the file to your system and click to open the file from your hard drive. Try Edge or Internet explorer if Chrome doesn’t work correctly. If it still doesn’t display accurately, notify GeneticAffairs at info@geneticaffairs.com. Consider this software release late alpha or early beta. Personally, I’m just grateful for the tool.

When you first open the html file, you’ll be able to see your matches “fly” into place. That’s pretty cool. Actually, that’s a metaphor for what I want all of my genealogy to do.

This grid shows the people who match me and each other as well, so a trio – although this does NOT mean the three of us match on the same segment.

The first person is Debbie, a known cousin on my father’s side. She and all of the other 12 people match me and each other as well and are shown in the orange cluster at the top left.

I know that my common ancestor couple with Debbie is Lazarus Estes and Elizabeth Vannoy, so it’s very likely that all of these same people share the same ancestral line, although perhaps not the same ancestral couple. For example, they could descend from anyone upstream of Lazarus and Elizabeth. Some may have known ancestors on either the Estes or Vannoy side, which will help determine who the actual oldest common ancestors are.

You’ll notice people in grey squares that aren’t in the cluster, but match me and Debbie both. This means that they would fall into two different clusters and the software can’t accommodate that. You may find your closest relatives in this grey never-never-land. Don’t ignore the grey squares because they are important too.

The second green cluster is also on my father’s side and represents the Vannoy line. My common ancestor with several matches is Joel Vannoy and Phoebe Crumley.

Working my way through each cluster, I can discern which common ancestor I match by recognizing my cousins or people who I’ve already shared genealogy with.

The third red cluster is on my mother’s side and I know that it’s my Jacob Lentz and Fredericka Ruhle line. I can verify this by looking at my mother’s AutoCluster file to see if the same people appear in her cluster.

You can also view this grid by name, # of shared matches and the # of shared cMs with the tester. Those displays are nice but not nearly as informative at the AutoClusters.

Scroll for More Match Information

Be sure to scroll down below the grid (yes, there is something below the grid!) and read the text where you’re provided a list of people who qualify to be included in the clusters, but don’t match anyone else at the criteria selection level you chose – so they aren’t included in the grid. This too is informative.  For example, my cousin Christine is there which tells me that our mutual line may not be represented by a cluster. This isn’t surprising, since our common ancestor immigrated in the 1850s – so not a lot of descendants today.

You’re also provided with AutoCluster match information, including whether or not your match has a tree. I do have notes on my matches at Family Tree DNA for several of these people, but unfortunately, the file download did not pick those notes up.

However, the fact that these matches are displayed “by cluster” is invaluable.

You can bet your socks that I’m clicking on the “tree” hotlink and signing on to FTDNA right now to see if any of these people have recognizable ancestors (or surnames) of either Elizabeth Vannoy or Lazarus Estes, or upstream. Some DO! Glory be!

Better yet, their DNA may descend from one of my dead-ends in this line, so I’ll be carefully recording any genealogical information that I can obtain to either confirm the known ancestors or break through those stubborn walls.

Dead ends would become evident by multiple people in the cluster sharing a different ancestor than one you’re already familiar with. Look carefully for patterns. Could this be the key to solving the mystery of who the mother of Nancy Ann Moore is? Or several other brick walls that I’d love to fall, just in time for Christmas. Who doesn’t have brick walls?

By signing on to Family Tree DNA and looking carefully at the trees and surnames of the people in each group, I was able to quickly identify the common line and assign an ancestor to most of the matching groups.

This also means I’ll now be able to make notes on these matches at Family Tree DNA paint these in DNAPainter! (I’ve written several articles about using DNAPainter which you can read by entering DNAPainter into the search box on this blog.)

Mom’s Acadian Cluster

Endogamy is always tough and this tool isn’t any different. Lots of grey squares which mean people would fit into multiple clusters. That’s the hallmark of endogamy.

My Mom’s largest clustered group is Acadian, which is endogamous, and her orange cluster has a very interesting subgroup structure.

If you look, the larger loosely connected orange group extends quite some way down the page, but within that group, there seems to be a large, almost solid orange group in the lower right. I’m betting that almost solid group to the right lower part of the orange region represents a particular ancestral line within the endogamous Acadian grouping.

Also of interest, my Mom’s green cluster is the same as my red Jacob Lentz/Frederica Ruhle cluster group, with many of the same individuals. This confirms that these people match me and that other person on Mom’s side, so whoever in this group matches me and any other person on the same segment is triangulated to my Mom’s side of my genealogy.

You can also use this information in conjunction with your parental bucketing at Family Tree DNA.

In Summary

I’m still learning about this tool, it’s limitations and possibilities. The software is new and not bug-free, but the developer is working to get things straightened out. I don’t think he expected such a deluge of desperate genealogists right away and we’ve probably swamped his servers and his inbox.

I haven’t yet experimented with changing the parameters to see who is included and who isn’t in various runs. I’ll be doing that over the next several days, and I’ll be applying the confirmed ancestral segments I discover in DNAPainter!

This is going to be a lot of fun. I may not surface again until 2019😊
