Leave No Stone Unturned, No Ancestor Behind: 10 Easy Steps to Capture DNA Clues

There’s a lot, a whole lot that DNA testing can tell you. Not just your own tests, but the genetic information carried by your relatives that you do not.

Recently, I’ve been reviewing my brick walls, which led me to realize there are several ancestors who are missing their mitochondrial DNA and/or Y-DNA  results. I need these to learn more about my ancestors that can’t be revealed any other way – and to break down those pesky brick walls.

I’ve solved two mysteries recently, one thanks to a Big Y-700 test, and a second very unexpectedly thanks to mitochondrial DNA – both thanks to cousins who tested. These revelations were very encouraging, especially since there’s no way other than DNA for me to break through these brick walls. The mitochondrial test had been sitting there, waiting for what seemed like forever until just the right other person tested.

I am in the process of unlocking several brick-walled ancestors by providing testing scholarships to people who are appropriately descended from known ancestors in those lines.

Don’t leave information on the table. If I were to tell you there even MIGHT be a book available about your family, you’d overturn Heaven and Earth to find it – but you don’t need to do that. All you need to do is order DNA tests for cousins.

All cousins can provide useful autosomal DNA results, but you do need to find appropriate cousins for Y-DNA and mitochondrial DNA testing.

I’m sharing the steps for how I accomplish this! You’ll be amazed at what’s out there – and someone may already have tested!

Take Advantage of the Holidays

I’m sharing NOW because it’s the holidays and you’re likely to gather with people you don’t see any other time – and because the best sale of the year for both Y-DNA and mitochondrial DNA lasts from now through the end of the year.

These two factors combined mean strike while the iron is hot.

Prices for new tests and bundles are at an all-time low.

If you or your relatives have already taken a lower-level test, now is the time to upgrade to either the Big Y-700 or the mtFull Sequence test.

Step 1 – Test Yourself and Your Known Family

If you’re a male, order both the Big Y-700 test and mitochondrial DNA tests.

Be sure to click on “See More” for more useful tools.

When you receive your results, be sure to click on all of the tabs in your results, and do the same by clicking through to Discover from your account. Discover has 13 more goodies for you to help with your genealogy.

Both your personal page and Discover are essentially chapters of your own personal book about your DNA results. 25 very interesting chapters, to be precise, that are uniquely you.

I’ve written about understanding Y-DNA results here, and mitochondrial results here. My book, Complete Guide to FamilyTreeDNA, covers both along with Discover.

Discover provides robust information for Y-DNA haplogroups. If you’ve taken a Big Y-700 test, you’ll want to click through from your page to receive additional, personalized and more robust information than is available through the free public Discover tool. That said, the public version of Discover is an amazing tool for everyone.

After the new Mitotree is released for mitochondrial DNA, mitochondrial haplogroups will be available in Discover too.

I can’t even begin to stress how important these tools are – in particular the Time Tree, the Group Time Tree for members of group projects, and the Match Time Tree for your own matches.

Who Can Test For What?

Once you’ve tested yourself, you will want to take a look in your pedigree chart at branches further up your tree to see who can be tested to represent specific ancestors.

Let’s begin with my father’s side.

A mother contributes her mitochondrial DNA to all of her children, so your father carries the mitochondrial DNA of his mother.

If you’re a female, and your father is available to test, you’ll want to test BOTH his mitochondrial DNA and Y-DNA, because there’s no way for you to obtain that information from your own test. Females don’t have a Y chromosome, and men don’t pass on their mitochondrial DNA.

If you’re a male, you can test your own mitochondrial DNA and Y-DNA, but you’ll need to test your father’s mitochondrial DNA to obtain his mother’s. You might still want to test your father’s Y-DNA, however, because you may discover a personal family haplogroup. How cool is that??!! Your own tiny branch on the tree of mankind!

Your father’s mitochondrial DNA provides you with mitochondrial matches and haplogroup information for your paternal grandmother – in this case, Ollie Bolton.

If your father and his siblings can’t test, then all of the children of your paternal aunts carry your paternal grandmother’s mitochondrial DNA.

If they have no children or they can’t test, then the children of Ollie Bolton’s mother, Margaret Claxton/Clarkson all carry her mitochondrial DNA, and the children of Ollie’s sisters continue the line of descent through all daughters to the current generation.

The male children of Joseph “Dode” Bolton and Margaret Claxton carry his Y-DNA. Fortunately, that’s not one of our missing haplogroups.

Yes, you may have to climb up your tree and climb down various branches to find a testing candidate.

One of the reasons I’m using this example is because, while I have a high-level haplogroup for my grandmother, Ollie Bolton, we need a full sequence tester – and I’m offering a mitochondrial DNA testing scholarship for anyone descending from Margaret Claxton (or her direct female ancestors) through all females to the current generation, which can be male.

Ok, now let’s switch to the maternal side of your tree.

On the other side of your tree, your maternal grandfather or your mother’s brothers will provide the Y-DNA of your mother’s father’s line. Your mother’s uncles or their sons will provide your grandfather’s Y-DNA line, too. In this case, that’s John Whitney Ferverda, who carries the Y-DNA of his father, Hiram Bauke Ferverda/Ferwerda.

Your maternal grandfather or his siblings will provide the mitochondrial DNA of their mother, Evaline Louise Miller.

If they are deceased or can’t test, for mitochondrial DNA, look to the children of Evaline Miller’s daughters or their descendants through all females to the current generation, which can be male.

And yes, in case you’re wondering, I do need Evaline Miller’s mitochondrial line too and am offering a scholarship.

You might have noticed that I’ve been inching my way up my tree. All of my immediate relatives have passed over already, so I’m now looking for testers that I don’t know but who I’m related to.

If you’re seeing family members anytime soon, figure out if their Y-DNA, mitochondrial DNA, or autosomal DNA would be useful for your common genealogy. Take advantage of the opportunity.

Next, you’ll want to figure out which ancestors need haplogroups and locate appropriate cousins.

Step 2 – Identify Ancestors Who Need Haplogroups

Peruse your tree to determine which of your ancestors you need haplogroup information for. To make it easy, on my computer, but never in a public tree anyplace, I store the haplogroup of my ancestor as a “middle name” so I can easily see which ones I have and which ones I need. Sometimes, I have a high-level haplogroup and either need a new tester or someone to upgrade.

Sometimes, I have one tester from a line but need a second for confirmation.

In this example, I’m not missing confirmation on any Y-DNA haplogroups (although I am further upstream on different lines,) but I do need four different mitochondrial DNA lineages.

For easy reference, make a list of all of the lines you can’t confirm with two testers from different children of the same ancestor.

You just might get lucky and discover that someone has already tested!

Step 3 – Check FamilyTreeDNA Projects

Check FamilyTreeDNA Projects to see if someone has already tested to represent those ancestors on your list.

Click here for the Group Project Search. It’s located at the very bottom of the main FamilyTreeDNA page in the footer.

I’m going to use Estes as an example since I’m the volunteer administrator of that project and am very familiar with the lineages.

I’m searching for projects that include the surname Estes.

The projects displayed on the list are projects where the volunteer administrators listed Estes as a possible surname of interest. It doesn’t mean those projects will be of interest to everyone or every line with that surname, but evaluate each project listed.

You probably want the surname project, but if there’s not a surname project for your surname, try alternate spellings or consider checking other projects.

You can see at the bottom that 384 people of both sexes by the surname of Estes have tested at FamilyTreeDNA.

Now, let’s look at the Estes project. Note that not everyone with the Estes surname has joined the Estes project.

I’ve clicked on the “Estes” link which takes me to an additional information page where I can read a description and click to view the project.

For the Estes project, you do not have to join to view the results. Nor does your surname have to be Estes. All Estes descendants of any line are welcome. Everyone can benefit from the Advanced Matching within project feature to see who else you match within the project by selecting a wide range of individual and combined filters.

Click on the Project Website link shown in the search results.

If you’re searching for a male Estes ancestor, you’ll want to review the project’s Y-DNA Results and the Group Time Tree, for sure, and possibly the Map as well.

Let’s pretend I’m trying to determine if anyone has tested who descends from my ancestor, Abraham Estes, the founding Estes ancestor in Virginia who arrived in the mid-1600s.

In the Estes project, the volunteer administrator has divided the Estes male participants by sons of Abraham, the immigrant. Only three are shown here, but there are several.

Some of the participants have completed their Earliest Known Ancestor information, in the red box. Sometimes people don’t think to update these when they make breakthroughs.

If you descend from Abraham’s son, Sylvester, three men have taken the Big Y-700. That’s the test results you need.

If you descend from Abraham’s son, Abraham, no project participants have taken the Big-Y test to represent that line, although six people have tested, so that’s great news. Maybe you can offer an upgrade scholarship to one or some of those men.

In other words, to establish the haplogroup for that lineage, at least two men need to test or upgrade to the Big Y-700, preferably through two different sons of the common ancestor. A new, more defining haplogroup is often formed every two or three generations for Y-DNA.

Your genetic pedigree chart looks a lot like your genealogy pedigree chart.

Click any image to enlarge

The project Group Time Tree shows selected groups of men who have taken Big Y tests, along with their Earliest Known Ancestor, if they’ve provided the information. This is one of the reasons why the Big Y-700 is so critically important to genealogy. The time granularity is amazing and can answer the question of whether men by the same surname descend from the same common ancestor – and when.

If you’ve taken a Family Finder autosomal test at FamilyTreeDNA, or uploaded an autosomal file from another vendor, you may match one of these men or another male that descends from the Estes line if they, too, have taken an autosomal test.

This same process applies to mitochondrial DNA, but generally surname projects aren’t (as) relevant for mitochondrial DNA since the surname changes every generation. However, sometimes other projects, such as the Acadian AmerIndian Project are quite beneficial if you have Acadian ancestry, or a geographic or regional project like the French Heritage Project, or something like the American Indian Project.

Another great way to find testers is by utilizing your Family Finder test.

Step 4 – Family Finder at FamilyTreeDNA

The next step is to see if you match anyone with the surname you’re searching for by using your autosomal test results, so select your Family Finder Matches.

At FamilyTreeDNA you’ll want to search your matches by the surname you seek. This surname search lists any tester who has that surname, or anyone who has entered that surname in their surname list. Please note that this search does NOT read ancestors in your matches’ trees. You’ll still need to view trees.

Reviewing the 32 Estes Family Finder matches reveals several men, but one man with the Estes surname has already taken a Y-DNA 25-marker test, so he would be an excellent candidate to offer a Big Y-700 upgrade scholarship. If he’s not interested or doesn’t respond, there are several more men to contact.

Click on your match’s name to display the profile card, along with the Earliest Known Ancestors, both Y-DNA and mitochondrial DNA haplogroups if they have tested, and the assigned haplogroup based on their testing level.

Craft an email and offer a testing scholarship. This will help both of you. I’ll provide a sample email at the end of this article.

If you match a female with an Estes surname, her father, brother, uncle or cousin may either have already tested or be willing.

If you match someone who has a different surname, that means they have an Estes surname in their surname list and may know a potential tester. If your match has a tree, click to check.

I’ve found that matching through a company where you’ve both tested is the easiest way to encourage someone to take an additional test, but certainly, it’s not the only way.

Step 5 – WikiTree

WikiTree is a quick and easy way to see if anyone has taken Y-DNA or mitochondrial DNA test that should reflect a particular ancestor’s Y-DNA or mitochondrial DNA.

I just googled “Moses Estes 1711-1787 WikiTree” and clicked to view.

Each ancestor includes both Y-DNA and mitochondrial DNA information, in addition to people who descend from that ancestor through only autosomal lines.

In this case, two men have provided their Y-DNA results that pertain to Moses Estes. They have tested at different levels, which is why they have different haplogroups. That doesn’t mean either is “wrong,” one is just more refined than the other. You can correlate their kit number with the Estes surname project. People often don’t update their haplogroup information at WikiTree when it’s updated at FamilyTreeDNA.

Please note that if the genealogy is wrong, either at WikiTree or individually, the haplogroup may not reflect the appropriate lineage for the ancestor. Check to be sure that there’s no conflict showing between two testers for the same ancestor. For example, the same ancestor clearly can’t have two different base haplogroups, like E and R. The Discover Compare tool can help you evaluate if two haplogroups are in the same part of the Y-DNA tree.

When possible, it’s always best to test a close family member to represent your lineage even if someone else has already tested.

Scan down the list of autosomal testers for that ancestor to see if there’s someone with the Estes surname.

WikiTree provides additional tools to find descendants.

Sign in to WikiTree. You’ll see the ID of the profile you’re viewing – in this case – Estes-167. Click the down arrow and select “Descendants.”

This view shows all descendants through five generations, but you can click on DNA Descendants to see only Y-DNA descendants, X-DNA, or mitochondrial DNA descendants for female ancestors.

You may find people who are living and have added themselves who you can contact to offer a DNA testing scholarship.

Step 6 – MyHeritage

At MyHeritage, you can also search your DNA matches by surname.

Click on “Review DNA Match” to view more detail, including locations. Look to see if you have a Theory of Family Relativity Match which suggests how you may be related. That’s golden!

There’s no Y-DNA information at MyHeritage, BUT, you can search by surname and view DNA matches that either carry that surname or have that surname in their tree as an ancestor.

I have a total of 75 “Estes” matches, and other than the kits that I manage, searching through my matches shows:

  • Two Estes men connected to the same small tree, but that’s OK, I’m a genealogist!

  • One Estes male match with a Theory of Family Relativity. My lucky day!

You can contact your match easily through the MyHeritage messaging system and offer a DNA testing scholarship at FamilyTreeDNA. You may also want to share your email address.

MyHeritage customers may not be familiar with Y-DNA or mitochondrial DNA testing, so you might want to share this article about the 4 Kinds of DNA for Genealogy.

MyHeritage testers can also upload their DNA file to FamilyTreeDNA for free to receive autosomal matches plus a complimentary mid-range Y-DNA haplogroup. This free haplogroup is not even close to the detailed resolution of a Big Y-700 test, but it’s something, and it may well be an enticing first step for people who are only familiar with autosomal testing.

Step 7 – At Ancestry

At Ancestry, select DNA Matches and then search by surname.

You can search by the surname of the tester, which is very useful, or by people who have Estes in their trees.

I started with the surname Estes, because it’s the most straightforward and I may find a perfect male candidate for Y-DNA. If someone’s “screen name” doesn’t show as Estes, they won’t appear in the results of this search. In other words, if your Ancestry screen name is “robertaestes” you won’t show in this search, but “Roberta Estes” will.

For mitochondrial DNA, you would want to search for the surname in your matches’ trees. Unfortunately, you cannot search for the specific ancestor in someone’s tree, at least not directly.

Of my 19 Estes surname matches, ten are males, and of them:

  • Three have unlinked trees
  • Three have very small linked trees, but I can work on extending those if need be
  • Three have public linked trees AND a common ancestor, which means ThruLines

I can review which ancestor we share by clicking on my match’s name

The Estes side of this man’s tree has only one person and is marked “private,” but Ancestry has suggested common ancestors based on other people’s trees. (Yes, I know trees are dicey, but bear with me.)

It’s also worth mentioning that you can be related through multiple lines. I share surnames from Acadian lines with this man, but that really doesn’t matter here because I’m only using autosomal matching to find an Estes male.

Click on “View Relationship” to see our common Estes ancestor’s ThruLine.

The ThruLine shows how Ancestry thinks we’re related on the Estes line.

I can also click on “View ThruLines” to see all Thrulines for John R. Estes, which shows four additional males, some of which did NOT appear in the Estes surname search, and some of which don’t appear further up the tree. In other words, check all Estes ThruLine ancestor generations.

Don’t rely solely on Ancestry’s surname search.

Go directly to your ThruLines on the DNA menu.

Ancestry only reaches back seven generations, which for me is Moses Estes and Luremia Combs. Moses has 95 matches, but he has been given some incorrect children. Again, for this purpose, it doesn’t matter. Within all ThruLine matches, I found three Estes males who all descend through John R. Estes. Check every generation.

However, Luremia Combs shows promise for mitochondrial DNA descendants. Unfortunately, only two of her daughters are represented in ThruLines, and both of their descendants descend through Luremia’s grandsons. That’s too bad, because I need Luremia’s mitochondrial DNA line.

It’s easy to message your Ancestry matches. You may want to mention that they can upload their DNA file to FamilyTreeDNA for free where they will receive more matches and males will receive a complimentary mid-level Y-DNA haplogroup.

Please note that, in general, ThruLines need to be evaluated very carefully and are prone to errors, especially if you accept Ancestry’s suggestions of ancestors instead of carefully building out your own tree. Regardless, you can still find Estes cousin matches in your match list and by using ThruLines to find people that do not show up in an “Estes” match search.

Step 8 – At 23andMe

At 23andMe, you can search for anyone who either has the Estes surname or has included that surname in their “Family surnames” list. Keep in mind that your matches at 23andMe are restricted to either 1500 if you don’t have a subscripition, or about 4500 if you do have a subscription.

On my match list, I have two males with the Estes surname.

23andMe provides a mid-level Y-DNA haplogroup. You can’t use this to confirm the lineage when comparing with FamilyTreeDNA, especially given that 23andMe provides no genealogy or user-provided tree, but it is a clue.

Both Estes men at 23andMe have Y-DNA haplogroup R-CTS241. You could use this in some cases to potentially eliminate these matches at 23andMe. For example, if men in your lineage in the Estes project are in haplogroup R and your 23andMe matches are showing as haplogroup E, or any other base haplogroup, their common ancestor is tens of thousands of years ago.

Comparing the 23andMe haplogroup, which in this case is about 4500 years old, to contemporary testers who have taken the Big Y-700, which reaches within a few generations, isn’t terribly useful. These matches are extremely useful to identify individuals to reach out to for further information and potentially offer a Y-DNA testing scholarship at FamilyTreeDNA.

Remember, this also applies to females who have included Estes in their family surnames, given that they may have Estes male relatives.

By clicking to view your match, you can see if they have provided Family Background information, including a link to a family tree someplace.

Sometimes, there’s great information here, and other times, nothing.

You can’t verify this lineage without genealogy information.

I suggest leaving a genealogy-focused message, including where they can see your tree in addition to your Estes connection. Also include your e-mail.

You may want to say that if they descend appropriately, you have a Y-DNA or mitochondrial DNA testing scholarship, or you may want to wait to see how they descend. You can also ask if they have already taken a Y-DNA or mitochondrial DNA test at FamilyTreeDNA.

Step 9 – FamilySearch and Relatives at RootsTech

We’re getting ready for RootsTech 2025 which takes place in March. In the month or so before the last two RootsTechs, FamilySearch provided an absolutely wonderful tool called “Relatives at RootsTech.”

I’ve written about this several times, but essentially, you can see, by ancestor, other people who are registered both in-person and virtually for RootsTech, and how they descend.

Here’s an example.

In both years, I’ve found several people who descended from common ancestors AND were very willing to take the relevant DNA test. That’s a huge win-win for everyone.

The best part is that because these people have freshly registered for RootsTech, the reply rate is almost 100%.

I’ll write about this as soon as RootsTech makes it available this year. Fingers crossed that they do!

Step 10 – Social Media

Social media wouldn’t be my first choice to find DNA testers, but I have found perfectly willing cousins this way. You may be less successful on Facebook or other social media platforms, but if you’re striking out elsewhere, there’s absolutely no downside to trying.

You can enter a surname and search on Facebook, but I prefer to do a Google search like “Estes genealogy on Facebook” or even just “Estes genealogy,” which will produce far more widespread information, some of which may be irrelevant.

That Facebook Google search provided the names of two groups. People join groups because they have an interest, and I’ve had good luck in Facebook genealogy groups.

A Search of “Estes” on Facebook itself, then selecting “people” provided a list of Estes Facebook users.

I’ve had far better luck by joining a group that is focused on Estes genealogy, or even a county genealogy group that includes Estes families, than individuals. People who join any Estes group or project likely have an interest in that surname.

If you have a common surname, or there’s a park named after your surname, like Estes Park, you’ll probably want to focus by using Google searches for Estes genealogy.

The Descendants of Abraham Estes Facebook group has 222 members, of whom at least 31 are males with the Estes surname. Facebook just might be an underestimated resource.

If there isn’t a genealogy-focused group for your surname, you might want to consider starting one and encouraging people to join.

It can’t hurt, and it just might help. Before you start reaching out to random people on Facebook, please do a privacy checkup – I wrote about how, here.

Sale Prices

Remember, the sale prices at FamilyTreeDNA for new tests and upgrades last through year-end.

In my experience, it’s best to test as soon as someone agrees. You never know what will happen otherwise. I’ve had people pass away before they could swab. And yes, we’ve done funeral home swabs, too.

There’s no one-size-fits-all, but here’s a rough draft contact letter.

Potential Contact Letter

You’ll want to include several critical pieces of information.

Essentially:

  • Introduce yourself
  • Say their full name on their test AND the testing company in the title of an email. I manage many tests and if I receive an email that says, “Hi, can you tell me how we match” without telling me which person they match, I can’t even begin to answer.
  • Explain your genealogy connection
  • State your purpose in writing
  • Explain how a specific test will help them too
  • Offer to answer questions

Be sure to modify this letter to reflect your own voice and circumstances. You don’t want this to read like a form letter.

Dear cousin (insert their full name here,)

It was so nice to find our DNA match at <company name> (or we share a common ancestor, or appropriate circumstance.) (If you are managing someone else’s kit, say the name of who they match and explain that you manage their DNA kit.)

I descend from (ancestor plus birth and death date) who lived in Halifax County, Virginia and was married to (spouse.) You can view my tree at (insert link that does not require a subscription for viewing unless you match them on that platform. I use MyHeritage because everyone can view their trees)

I would very much like to confirm that our line descends from Abraham Estes (or relevant information meaning your reason for wanting them to test.)

Given that my surname is x (or I’m a female), we need to test the Y-DNA of a male who is descended from (ancestor) through all males to the current generation. (Or mitochondrial DNA descended through females to the current generation which can be male.)

FamilyTreeDNA provides this testing and shows who you match on that specific line using the Y chromosome (mitochondrial DNA).

This testing may connect us with earlier ancestors. Genetics can be used to determine when we share common Estes ancestors with others who test, where we come from overseas, and when. Even if we match ancient DNA samples that may tell us where our ancestors lived before surnames. In other words, where did we come from?

(Include a nice paragraph, but not a book about your ancestral lineage here.)

I have a DNA testing scholarship for someone from this line and you are the perfect candidate. I would like to take advantage of the current sales. If you’re interested, I only need two things from you.

First, permission so that I can order (or upgrade) and pay for the test, and second, an address where to send the test (unless it’s an upgrade). (If it’s an upgrade at FamilyTreeDNA, they can use a stored sample or will sent them a new kit if there’s not enough DNA.)

If you have any questions, please let me know. I’m very excited that we may be able to learn more about our heritage.

Please email me at xxx or call me at xxx if you have questions.

Your name

I know one person who offers to review results over Zoom. Someone else stresses that the tester’s email is attached to their test and they are always in control of their results. Another person asks them to join a project they manage to assure that they can follow their matches over time.

Customize this communication in your own voice and to fit the circumstances of each match.

It’s just me, but since I’m ordering while the tests are on sale, unless the person uploads their DNA file from another vendor, I add on a Family Finder test too and explain why. You never know if they will match you or another cousin, and they may have that match that eventually breaks down the next brick wall. Shared matches are powerful evidence and it’s a lot easier to add that test on now than try to contact them again later.

You Don’t Know What You Don’t Know

Which ancestors do you need Y-DNA or mitochondrial DNA results for? Methodically check each line.

There’s so much to learn. Don’t leave information on the table by virtue of omission.

Leave no stone unturned!

You don’t know what you don’t know.

Who’s waiting out there for you?

Six Ways to Figure Out How We’re Related

In my latest Webinar, Six Ways to Figure Out How We’re Related, I discuss the various tools from Ancestry, FamilyTreeDNA, MyHeritage, and 23andMe – plus clusters from Genetic Affairs and the amazing DNAPainter.

This webinar lives in the Legacy Family Tree Webinar library, but as part of the “webtember” lineup, you can view it for free through the end of September.

It’s always exciting to discover a new match at one of the DNA testing companies, which, of course, begs the question of how you’re related.

So, what are the six ways to figure out how you’re related, and how do you use them?

Come along for a step-by-step guide!

Shared Matches

We begin with how each vendor handles shared matches, what that feature is called, where to find the information, and how to interpret what they are telling you.

23andMe goes a step further and creates a genetic tree, of sorts, although that functionality has changed since their breach last October.

Bucketing and Sides

Two vendors go a step further and provide unique tools to divide your matches maternally and paternally.

FamilyTreeDNA buckets your matches maternally and paternally (or both) based on matches you link to their profile cards in your tree. FamilyTreeDNA then uses your linked matches to triangulate with other matches and assign your matches accordingly, providing a maternal and paternal match list. Bucketing, also known as Family Matching, is one of my favorite tools.

Note that linking matches at FamilyTreeDNA requires that you have transferred your tree to MyHeritage. I wrote about that and provided instructions here and here, and produced a complimentary webinar, too.

Ancestry also divides your matches by parent, but they use a different technique based on their Sideview technology and either ethnicity or shared matches.

Surnames and Locations

Surnames and locations, either separately or together, provide HUGE hints!

MyHeritage provides a nice summary for each of your matches that includes ancestral surnames, a map of locations in common, and “Smart Matches” which shows you people in common in both of your trees. There are several ways to use these tools.

FamilyTreeDNA also provides a list of surnames. You can view either the surnames in common with a match, or all of their ancestral surnames, with locations if provided. The tester enters these surnames, and we review how to complete that step.

Ancestry also provides shared surnames, with clickable links to the number of people in your matches tree with that surname, plus common locations.

X-DNA

X-DNA is probably the most underutilized DNA matching tool. While each of the vendors actually test the X chromosome, only one, FamilyTreeDNA, provides X-matching. You can obtain X-matching results by uploading your DNA file to FamilyTreeDNA. I’ve provided upload/download instructions for all companies, here.

X-DNA has a very unique inheritance pattern because males only inherit an X chromosome from their mother which limits the number of potential common ancestors for any two testers. In other words, X-DNA matching does half your work for you!

Clustering Technology – AutoClusters, the Matrix and DNAPainter

In the past few years, match clustering has become a very useful tool. Clustering shows which of your matches match you and each other.

Genetic Affairs offers several flavors of these clusters, and both MyHeritage and GEDmatch have incorporated Genetic Affairs clusters into their product offerings.

If you haven’t used AutoClusters yet, by all means, try them out.

FamilyTreeDNA offers the Matrix, a slightly different version of clustering. You can select 10 people from your match list to see if they also match each other. Shared matches don’t automatically mean triangulation between you and those two people, or even that all three people descend from the same line. However, if the people are bucketed to your same side (parent) and they share common segments with you in the chromosome browser, they triangulate.

You’ll want to paint those matches to DNAPainter to determine which ancestor you share, especially if they haven’t provided a tree.

DNAPainter provides your chromosomes as the “canvas” upon which to paint your matches in order to correlate segments with ancestors and identify common ancestral lines with mystery matches.

Three vendors, FamilyTreeDNA, MyHeritage, and GEDmatch provide segment information with matches for you to paint. I illustrate how I walk segments back in time, identifying our most distant common ancestor possible.

Theories of Family Relativity and ThruLines

Both MyHeritage and Ancestry provide a combination of DNA matching and tree triangulation, where they search the trees of your DNA matches to find common ancestors with you – although their implementation is different.

MyHeritage’s Theories of Family Relativity provides varying theories about common ancestors for you and a specific match using both trees and historical documents. You can review the various pathways and confirm or reject theories. I love this tool.

Ancestry’s Thrulines functions a bit differently, showing you all of your matches that descend from a common ancestor in all your matches’ trees. Sometimes, the trees are incorrect, but Theories of Family Relativity and ThruLines should still be used as hints.

I showed how ThruLines helped me discover what happened to one of my ancestor’s grandchildren who was lost to the family at his mother’s death – and to all of us since. Not anymore.

Bonus – Y-DNA and Mitochondrial DNA at FamilyTreeDNA

Only FamilyTreeDNA offers both Y-DNA and Mitochondrial DNA testing and matching. All of the tools above pertain to autosomal DNA testing, which is named Family Finder at FamilyTreeDNA. Illustrated by the green arrow below, autosomal DNA testing measures and compares the DNA you inherited from each ancestral line, but that’s not the only game in town.

Y-DNA, in blue, for males, tracks the direct paternal line, which is the surname line in Western cultures. Mitochondrial DNA, in red, is passed from mothers to all of their children. Therefore, everyone can test, revealing matches and information about their mother’s direct matrilineal lineage.

Y-DNA testing includes the amazing Discover tool with a baker’s dozen different reports, including ancient DNA. Mitochondrial DNA will soon have its own MitoDiscover after the rollout of the new Mitotree.

Both tests include “Matches Maps” to help you determine how you are related to your matches, as well as where your ancestors came from before the advent of surnames.

The Advanced Matching feature allows you to select multiple tests to see if your matches match you on combined types of tests.

Tune In

Now that you know what we cover in the webinar, please tune in to see how to use these awesome tools. Be sure to fish in all four “ponds” plus GEDmatch, where you may find people who didn’t test at a company that provides a chromosome browser or matching segment information.

Tools provided by the DNA testing vendors facilitate multiple ways to determine how we match and which ancestor(s) we have in common.

You can watch the webinar, here.

Additionally, subscribers to Legacy Family Tree Webinars have access to the 25-page syllabus with even more information!

Why Don’t Our Y-DNA Haplogroups Match?

I’ve been asked this question several times recently, and the answer is resoundingly, “it depends.” There are several reasons why Y-DNA haplogroups might not match and most of them aren’t “bad.”

How Haplogroups Work

Haplogroups are the 79,000+ branches of the Y-DNA phylogenetic tree which you can view here, along with countries where those haplogroups are found. You can think of haplogroups as genetic clans of either closely or distantly related men. Major haplogroup branches have unique letters assigned. Downstream or younger haplogroups are designated by a letter-number sequence that is always preceded by the main haplogroup letter.

Image courtesy FamilyTreeDNA

Major haplogroups were formed tens of thousands of years ago, with more recent haplogroups added as they’ve been discovered. Haplogroups are discovered and added every day thanks to the Big Y-700 test. You can read more about that process, here.

As you look at the pie chart above, you’ll notice that haplogroup R represents about half the men who have tested and has several major subbranches. Every haplogroup R man belongs to all of the branches above his own that lead back to the root of haplogroup R.

Using haplogroup R, which is R-M207, its identifying SNP, as an example, it immediately splits into two branches: R-M173, which has 37,000+ more branches, and R-M479, which has 313 branches. My Estes men fall into a haplogroup several steps beneath R-M173, but they are still members of haplogroups R-M173 and R-M207, even though their descendant haplogroup is R-BY490, which was formed by a mutation that occurred 20,000 years later.

Haplogroup R-M173, then, in turn, leads back to Y-Adam, the first man to have lived and has descendants today.

As we approach the question of why haplogroups of two men might differ, we will review tools to use and how to interpret your findings to reach the appropriate answer for your situation.

What is Your Goal?

You may be looking for a very specific answer, or this may be a more general question.

  • If you’re evaluating closely related men who have different haplogroup assignments, not matching can be very disconcerting. Breathe. There are several perfectly legitimate reasons why they may not match, and we have easy, free analysis tools.
  • If you’re looking at your Y-DNA match list at FamilyTreeDNA, you may or may not match other men closely, but you do “match” at some level if they are on your match list. You may see several different haplogroups in your match list. How closely you match those men is a different question.
  • If you’re looking at autosomal results at FamilyTreeDNA, you may see haplogroups listed for males. You may or may not “match” the haplogroup of men with the same surname. What does this mean, and why don’t you match? Your autosomal match may have nothing to do with your paternal line, or it may be because of your paternal line.

We will cover all of these scenarios.

Where Did You Both Test?

  • Are you comparing apples and apples?
  • Did you both test at the same company?
  • Did you both take the same type or level of test?

These factors all make a difference.

Which Test Did You Take?

There are four types of tests that will provide males with some level of Y-DNA haplogroup.

Autosomal Tests – Some companies include a few Y-DNA location probes in their autosomal test, meaning that they test a few haplogroup-specific Y-DNA locations. LivingDNA, 23andMe, and FamilyTreeDNA’s Family Finder test provide a mid-level Y-DNA haplogroup to customers. The haplogroup that can be determined from these tests depends on a variety of factors, including the vendor, the probes they selected for their chip, the test version, and if that location is successfully read in the test.

Note that FamilyTreeDNA supports autosomal uploads from MyHeritage and Ancestry who do not provide Y-DNA haplogroups to customers, but who do test some Y-DNA locations. Therefore you can upload your autosomal test from those companies to FamilyTreeDNA for free and receive at least a cursory Y-DNA haplogroup.

FamilyTreeDNA is currently processing all of its Family Finder tests, followed by tests uploaded from other vendors, to provide all genetic male testers with a Y-DNA haplogroup at some level. Different vendors and test versions test different Y-DNA SNPs, so your mileage may vary. Y-DNA haplogroups are a free benefit at FamilyTreeDNA.

STR Tests – At FamilyTreeDNA, you can purchase both Y-37 and Y-111 STR (short tandem repeat) Y-DNA tests that provide matching at the number of locations you purchased, plus a predicted haplogroup based on those results. These haplogroup predictions are accurate but are often relatively far back in time.

If you match someone on STR tests, your match may be very recent or before the advent of surnames. For a more specific haplogroup, you need to purchase the Big Y-700 test, which provides at least 700 STR match locations but, more importantly, sequences the entire gold-standard region of the Y-chromosome for the most precise haplogroup and matching possible.

  • When viewing matches of two men who ONLY took STR tests, STR marker matches are more important for genealogy than haplogroups because the haplogroups were formed thousands of years ago.
  • When viewing matches on the Big Y-700 test, haplogroup matching is much more specific and reliable than STR matches because the mutations (SNPs – single nucleotide polymorphisms) that form haplogroups are much more stable than STRs which mutate unpredictably, including back mutations.

SNP Confirmation Tests – Historically, FamilyTreeDNA customers could purchase individual SNPs to confirm a haplogroup, or SNP packs or bundles to do the same for a group of SNPs. With the advent of both the Family Finder haplogroup assignments, and the Big Y-700, these individual tests are no longer necessary or advantageous and are being discontinued.

Big Y-700 Test – At FamilyTreeDNA, the Big Y-700 test provides the most granular and specific haplogroup possible, most often well within a genealogical timeframe. You may be able to tell, based on previously undiscovered mutations, that two people are brothers or father and son, or, depending on who else has tested and when mutations formed, testers may match further back in time. Here’s an example of using the results from multiple testers in the Estes DNA Surname Project.

You can also match men who took the Big Y-500 test which is less specific than the Big Y-700. In the now-obsolete Big Y-500 test, a smaller portion of the Y chromosome was sequenced and testers only received about 500 STR locations. The Big Y-700 test has been enriched to provide a wider range of more specific information. Men who originally took the Big Y-500, then upgraded to the Big Y-700, will very probably have a new haplogroup assignment based on the expanded coverage and increased resolution of the Big Y-700 test. The Big Y-700 ferrets out lineages that the Big Y-500 simply could not, and continues to provide additional value as more men test, which facilitates the formation of new haplogroups.

What Do You Mean by Match?

Matching doesn’t mean you have to have the exact same haplogroup. A perfectly valid match can have a different haplogroup because one haplogroup is more specific or refined than the other. Matching exactly as a result of a predicted STR haplogroup is much less useful than matching closely on a much more recent Big Y-700 haplogroup.

Not all haplogroups are created equal.

I know this is a bit confusing, so let’s look at real-life examples to clarify.

STR to STR or Autosomal to Autosomal Haplogroup Match

Two males might match exactly on a mid-range Family Finder autosomal haplogroup or on a STR-predicted haplogroup like R-M269, which is about 6350 years old.

This haplogroup “match,” even though it might be exact, does not confirm a close match and really only serves to eliminate some other haplogroups and confirm that a closer match is possible. For example, R-M269 men don’t match someone in haplogroup J or E. You may or may not share a surname. You may or may not still “match” if you both upgrade to the Big Y-700.

In this case, a father/son pair would match exactly, as would two men with different surnames whose common ancestor lived 6000 years ago.

Note that if you’re comparing autosomal-derived haplogroups across different vendor platforms, or even different DNA testing chip versions on the same platform, you may see two different haplogroups. Different vendors test different locations. Please note that second cousins and closer will always match on autosomal DNA, but relationships further back than that may not. Y-DNA very reliably reaches far beyond the capabilities of autosomal DNA due to the fact that it is never mixed with the DNA of the other parent – so it never divides or is watered down in time. When comparing two autosomally-generated haplogroups of men who are supposed to be closely related, always check their autosomal match results too.

Use the free Discover Tool to find various categories of information about any haplogroup, including its age. Take a look at R-M269 here.

Using Discover to Compare Haplogroups

You can always use the Discover tool to compare two haplogroups.

Go to Discover (or click through if you’re signed on to your FamilyTreeDNA Y-DNA page), then enter the first haplogroup you’d like to compare.

Click search to view information about that haplogroup.

On the menu bar, at left, click on Compare.

Add the second haplogroup.

I’m selecting E-M35, a completely different branch of the phylogenetic tree.

R-M269 was formed about 6350 years ago, while E-M35 was formed about 25,000 years ago. Their common ancestor was formed about 65,000 years ago. Clearly, these two paternal lineages are not related in anything close to a genealogical timeframe.

These two men would never match on an STR test, but could easily match on an autosomal test on any line OTHER than their direct paternal line.

Now let’s compare two haplogroups that are more closely related.

Haplogroup R-M222 is very common in Ireland, so let’s see how closely related it is to R-M269 which is very common in western Europe.

We see that R-M222 descends from R-M269, so there is no “other haplogroup” involved.

R-M222 was formed about 2100 years ago, around 4250 years after R-M269 was formed.

There are 17 steps between R-M222 and R-M269.

The bottom block shows the lineage from R-M269 back to Y-Adam.

How cool is this??!!

Big Y-700 to Autosomal or STR Haplogroup Comparison

Joe took the Big Y-700 test and discovered that he’s haplogroup R-BY177080.

Joe noticed that his son, who had initially taken an STR test, had been assigned haplogroup R-M269. Then, his son took a Family Finder test and his haplogroup changed to R-FGC8601.

Joe was confused about why he and his son’s haplogroups didn’t match.

First, let’s check Family Finder to confirm the parent/child relationship. Joe’s son is clearly his son.

So why doesn’t Joe’s son’s haplogroup match Joe’s haplogroup? And why did Joe’s son’s haplogroup change?

Joe’s son had not taken a Big Y-700 DNA test, so Joe’s son’s R-M269 haplogroup was initially predicted from his STR test.

Joe’s son’s updated haplogroup, R-FGC8601 was generated by the Family Finder test. Think of this as a bonus. If you’re a male and haven’t yet, you’ll soon receive an email telling you that you’ve received a Family Finder Y-DNA haplogroup. It’s your lucky day!

Family Finder haplogroups always replace STR predicted haplogroups since they are always more specific than predicted STR haplogroups. Big Y-700 haplogroups always replace STR-generated haplogroup predictions and Family Finder haplogroups because they are the most specific.

Let’s compare these results using Discover.

Joe’s son’s original predicted haplogroup was R-M269.

Discover Compare shows us that Joe’s Big Y-700 Haplogroup, R-BY177080, is a descendant of R-M269.

So, they actually do “match,” just several branches further up the tree

Joe’s son’s more precise Family Finder haplogroup was assigned as R-FGC8601.

Discover Compare shows us that Joe’s Big Y-700 haplogroup also descends from R-FGC8601.

You can see that the haplogroup generated by Family Finder is more precise by about 4700 years and improves that comparison.

R-M269 was formed about 6350 years ago, but R-FGC8601 was formed about 1700 years ago.

Joe’s Big Y-700 haplogroup, R-BY177080 was formed about the year 1900, improving the family haplogroup by another 1600 years or so.

Joe’s son’s Family Finder haplogroup moved down the haplotree 21 branches and 4650 years, for free! If Joe’s son were to upgrade to the Big Y-700, they might very well be assigned a new haplogroup that, for the time being, only they share.

Of course, Family Finder doesn’t provide Y-DNA matching so you still need the Y-DNA tests for that important aspect of genealogy.

Big Y to Big Y Comparison

In our next example, a group of men, including a father and son or other very close relative may take the Big Y-700 test and have different haplogroups. If you’re saying, “Whoa Nelly,” hear me out.

George took a Big Y-700 test and discovered that he is haplogroup R-FGC43597. His son and grandsons tested, and they are haplogroup R-FTC50269. What happened? Shouldn’t they all match George?

On George’s Big Y-700 block tree, you can see that a mutation, R-FTC50269, occurred between George and his son. George doesn’t have it, but his son does.

A haplogroup isn’t “named” until there are two men with the same mutation in the same lineage. Therefore, when George’s son initially tested, he would have been assigned to the same haplogroup as George, R-FGC43697, but with one extra variant, or mutation.

Of course, that extra mutation was passed from George’s son to both of his grandsons, so when the first grandson tested, the new haplogroup, R-FTC50269 was assigned as a result of that mutation. Now, George has one haplogroup and his son and grandsons have a different haplogroup, one branch downstream.

Using Discover to check the haplogroup ages and path, we find that indeed, these haplogroups are only one step apart.

Checking Family Finder results can always verify that the match is close or as close as you expected.

Haplogroup Assignments

Haplogroup assignments range from good to better to best.

Good Better Best
STR predicted Yes – but further back in time
SNP Packs (now obsolete) Between good and better
Family Finder autosomal Yes – generally midrange between STR predicted and the Big Y-700
Big Y-500 (need to upgrade) Usually between better and best
Big Y-700 The best – usually within a genealogically relevant timeframe unless your DNA is rare

Where Are You?

Older haplogroups, such as the STR-predicted haplogroups are useful for:

  • Eliminating some potential matches
  • Identifying where that haplogroup originated at that specific point in time. In other words, where your ancestor lived when that haplogroup was born.

If your Y-DNA matches another Y-DNA tester at FamilyTreeDNA, your haplogroups will fall someplace on the same haplogroup branch, although they may be thousands of years apart. STR-predicted haplogroups are “older,” meaning they range in age from about 6500 years to tens of thousands of years ago. They can tell you where the haplogroup originated at that time.

Autosomal haplogroups will be newer, or more recent, than STR-predicted haplogroups, but still (sometimes significantly) older than the Big Y-700 haplogroups..

FamilyTreeDNA provides Y-DNA haplogroups for free for every biological male who either takes the FamilyTreeDNA Family Finder test or uploads an autosomal result from either Ancestry or MyHeritage. Soon, 23andMe uploads will be resumed as well. This means that you will be able to view other men with a similar surname in your Family Finder results and:

  • Rule them out as a paternal line match.
  • Check your STR matches if they have taken a Y-DNA test
  • Check your Big Y-700 test for matches if both men have taken a Big Y test.
  • Encourage your matches to take a Big Y-700 test so you can see how closely you match on your paternal line.
  • Use the Discover Compare and other tools to reveal more information.

Family Finder haplogroups are relatively new, so currently, all new Family Finder testers are receiving haplogroups. Older Family Finder tests are being processed and will be followed by autosomal tests uploaded from other vendors. Haplogroups from autosomal tests are confirmed and will be newer, or more recent, than STR-predicted haplogroups.

The only test that can bring your haplogroup to current, meaning the most refined, recent, personal haplogroup, is the Big Y-700 test. Without taking the Big Y-700 test, you’ll forever be stuck with an older, less informative haplogroup branch. The Big Y-700 allows us to reliably sort families into lineages based on branching mutations.

The Big Y-700 haplogroup is:

  • The most detailed and granular possible.
  • Determined by sequencing the Y chromosome.
  • A test of discovery that continues to provide additional value as more men test and new haplogroups are formed.

Big Y-700 haplogroups generally fall into a genealogically useful timeframe and can be very recent.

The Discover tool and Time Tree provide a wealth of information about your ancestors, including locations, migration paths, ancient DNA, and more.

You Don’t Know What You Don’t Know

Now that you understand how to compare and interpret haplogroup matches, what additional information can you learn?

I always encourage Y-DNA matches to upgrade to the Big Y-700. Why? You don’t know what you don’t know. The article, Bennett Greenspan: Meet My Extended Family & Discover Extraordinary Deep Heritage illustrates the benefits of the Big Y-700 for all matches. Upgrading 12-marker matches is exactly how he made his big breakthrough.

The Big Y-700 test answers many questions beyond simply matching by using Discover and the Group Time Tree.

  • Where were your ancestors?
  • Who do you match, and who were their ancestors?
  • Genetically and genealogically, how do your surname matches fit together?
  • Where were your matches’ ancestors, and when?
  • Which ancient DNA results do you match, and where were they located?
  • What is the history of locations where your ancestors were found along their journey?
  • How closely or distantly are you related to other Big Y-700 matches?
  • Can your matches’ information break down your paternal line brick wall, or at least move it back a few generations?

Where are your Y-DNA results along the spectrum of useful haplogroup information? Do you or your matches need to upgrade? Click here to upgrade or order a Big Y-700 test.

Bennett Greenspan: Meet My Extended Family & Discover Extraordinary Deep Heritage

“My ancestors are in my soul. I can’t get them out of my mind.”

Bennett Greenspan

“And yes, I brake for cemeteries.”

Bennett Greenspan gave an incredibly interesting presentation at the 15th International Genetic Genealogy Conference held by FamilyTreeDNA in November 2023. Since his retirement in January 2021, he has been able to focus on his genealogy. Once a genealogist, always a genealogist.

Bennett said some things I hadn’t thought about, and now I’m viewing Y-DNA matches with a different perspective – based on how he’s using his results.

Ever since I met him, Bennett’s focus has been to use genetics to unravel his complex Jewish heritage.

The questions that drive Bennett are the same ones that motivate most genealogists:

  1. Who are we?
  2. Where did we come from?
  3. Where were we before we were there?
  4. How did my ancestors get there?

Bennett “lost his family lines” before the mid-1800s due to his Jewish heritage, exacerbated in the 1930s by the devastation wrought by the Holocaust. Families were either killed or scattered to survive. It has been through Y-DNA in particular that he has been able to establish unquestionable and confirmed connections with other Greenspan men, sometimes by similar but different surnames, like Green, and sometimes with other surnames entirely.

When Bennett first started down this path, he tested more than 62 men before actually finding one a decade later that matched his Y-DNA. Bennet commented that it was “a little frustrating.”

Persistence is the key, and sometimes, genealogy is a waiting game, but that’s small comfort to genealogists during that unproductive waiting period.

Eventually, Bennett reassembled his family, at least somewhat, but it was a long journey. Here’s Bennett’s incredible story, including surprises, as he tells it.

Bennett discovered genealogy at age 12 and, like many genealogists, created a pedigree chart by talking to his family.

I love the mark-outs. How many of us still have our first chart with its edits?

This is the young Bennett Greenspan, whose interest in genealogy would one day unlock secrets for all of us!

It was a long way from a decade with no matches to finding his genetic kin in Ukraine.

The Big Y-700 Time Tree shows Bennett’s lineage in Ukraine, but stepping back in time, some descendants of his ancestors are found in adjacent locations.

Bennett was passionately discussing his matches on the time tree and in the Greenspan project, so I visited the Greenspan DNA Project, where the earliest known ancestors of Bennett’s Big Y matches are shown on the Group Time Tree.

Bennett’s closest matches are shown as descendants of haplogroup J-ZS1718. He has additional matches who are not in the Greenspan project. Since this is the Group Time Tree, it only displays the people in that project, along with their earliest known ancestors, Isaac and Usher Greenspan.

12-Marker Matches

Bennett never fails to amaze me. He said something very important and profound about 12-marker matches that I really hadn’t thought about – at least not this way.

As a community, we are often guilty of discounting 12-marker matches, those that don’t match us at 25-markers or above, or with different surnames, as “too far back in time” or otherwise irrelevant. I always look at the names and earliest known ancestors of 12-marker matches, because that person may have tested back in the day when fewer markers were available. But if I don’t recognize something, I move on.

However, Bennett said that, ”Y-12 matches reach back to a common ancestor. 12-marker matches are not a quirk. They are related to you, just further back in time. You share a common ancestor with them, someplace. They may be more distant, but they are still your close matches.”

I’ve been in too much of a hurry for a quick win, and ignoring the (apparently not so) obvious.

Determining when and where their ancestors lived also paves the way to discover yours. Your Y-DNA and theirs were in the same place at the same time.

Of Bennett’s 171 12-marker matches, 107 have upgraded to the Big Y, probably mostly due to his encouragement. This benefits both them and Bennett by fleshing out the history of that entire group of men, including how they got to where they are found in the first available records. The Time Tree shows when Big Y testers shared a common ancestor, and based on Earliest Known Ancestor (EKA) locations, where. This provides further information about the lives of ancestors before contemporary records – in other words – people that we can never identify by name. It’s a window into ancestors before surnames.

Bennett notes that testers need to know their ancestral village or location to be most useful within the project, and of course, they need to enter their EKA information. Location information is how the Migration Map, Matches Map, and Discover tools, including the Time Tree, are built.

What Happened in Spain?

Bennett’s ancestors and those of his 12-marker matches are found in Spain, and as Bennett says, “One son stayed and one left about the year 296.”

While we have no idea of their names, based on the Time Tree combined with the cluster of earliest known ancestors, we know that they were in Spain, and when.

Their family story is revealed in the bifurcation of the tree found beneath haplogroup J-L823, formed about 296 CE. One line stayed in Spain, and Bennett’s line migrated to eastern Europe where that man’s descendants, including Bennett’s family, are found in the Russian Federation, Belarus, Poland, Lithuania, Sweden, Slovakia, Ukraine, Germany, Romania, the Czech Republic, and other eastern European locations. The closer to you in the tree and in time, the more relevant to your more recent ancestral story.

However, Bennett’s deeper ancestry, the migration of his ancestors to Spain, was only revealed by testing those more distantly related men. Those same men could well have been ignored entirely because they only matched at 12 markers.

According to Bennett, “Y-12 markers are important because these are the men most closely related to you in a database of 1 million men.”

How incredibly profound. How much have I been cavalierly overlooking?

How does this actually apply to Bennett’s results?

Bennett’s Spanish Matches

Bennett has the following STR panel matches who indicate that their EKA are from Spain. You can see that they match Bennett on a variety of panels.

  • X = yes, match
  • No = no match
  • Blank = not tested at that level.

In the Big Y GD column, the genetic distance (GD) is displayed as 15/660 where 15 is the number of mismatches, or the cumulative genetic distance ABOVE the 111 panel, and 660 is the number of STR markers above 111 with results.

The Big Y-500 test guaranteed a minimum of 500 total STR markers, and the Big Y-700 guarantees a minimum of 700 total STR markers, plus multiple scans of the balance of the Y chromosome for SNP mutations that define haplogroups. Testers don’t receive the same number of markers because the scan technology sometimes doesn’t read a specific location.

Tester 12 25 37 67 111 Big Y Test Big Y GD Big Y Match Haplogroup
AA X X X No No Yes 15/660 No J-FTD8826

XG X X X No No Yes 17/523 No J-BY167283
JA X X No No No Yes 15/646 No J-FTD11019

Of those 23 Spanish matches, sixteen have upgraded to Big Y tests, 14 of which are Big Y-700s, resulting in nine different haplogroups, all of which are descendants of Haplogroup J-L823. How cool is that?

The “Nos” in the Big Y Match Column aren’t mistakes. That’s right – none of these men match Bennett on the Big Y test, meaning they had more than a 30 mutation difference between them and Bennett on the Big Y test.

At first glance, you’d think that Bennett would have been disappointed, but that’s not the case at all! In fact, it was the information provided by these distant Spanish matches that provided Bennett with the information that his line had split sometime around the year 296 CE, with one branch remaining in Spain and his branch migrating to Eastern Europe, where he has lots of matches.

DNA Plus History

What was happening in Spain or the Iberian peninsula that involved the Jewish people about that time? Historical records exist of Jews living in that region before the fall of the Second Temple in about 70 CE, including records of Jews being expelled from Rome in 139 for their “corrupting influence.”

Furthermore, the Ancient DNA Connections for haplogroup J-L823, the most recent common ancestor (MRCA) for all of those branches, includes connections to multiple burials from:

  • Lebanon
  • Iran
  • Rome (from 1-400 CE)
  • Turkey
  • Jordan

Clearly, Bennett’s ancestor was in the Iberian peninsula around or before 296 CE. One branch stayed, winding up in Spain, and one headed for Europe.

Without these matches, some who didn’t match above the 12 or 25 marker level, how would Bennett have EVER known that his Jewish ancestors left the Middle East for Spain in the early years? How would he have known they migrated from Spain to Eastern Europe, and how would he have known that his line did not migrate directly from the Levant to Eastern Europe in the 9th century?

Big Y matches are typically within about 1500 years, but non-matches are still INCREDIBLY valuable. Without them, you can’t completely assemble your family story.

I noticed on the Time Tree that in Bennett’s Eastern European line, one of his ancestor’s brother lineages includes the Katzenellenbogen Rabbinic Lineage derived from ancient DNA samples.

Bennett’s successes have resulted from contacting his matches and encouraging upgrades. So how did he do it? What’s the magic sauce?

Contacting Matches

How to contact matches successfully is a question I see often. In fact, FamilyTreeDNA recently wrote about that in an article, here.

Bennett’s methodology for contacting his matches to encourage an upgrade is that he sends an email explaining why he’s encouraging them to upgrade, followed by a 2nd email three days later.

Bennett tells the recipient that we are at an inflection point in time. “It’s winter, the wind is blowing hard, and many of the leaves are gone.”

In other words, we need to cast the net wider and capture what we can, while we can. Unfortunately, many early testers have died, and with them, chapters of history are perishing.

Collaboration is key. In addition to encouraging upgrades, Bennett also offers Zoom calls to these groups of men to explain the results if they are interested.

What a GREAT idea! I need to begin offering that as well.

Upgrade Request

Bennett reaches out to his matches at various levels, but he expects his closer STR matches, meaning at the 67 and 111 marker level with the fewest mismatches, to match him on a Big Y-700 test and connect someplace between 300-600 years ago, which helps everyone flesh out their tree.

Bennett’s email:

Hello <name>,

Since you have already made a sizable investment in your Y-DNA, you now know that we come from the dominant male Middle Eastern group (Haplogroup J) of men who <subject here>.

What’s really neat is that our Y-DNA has recently been found in an archaeological site in Northwestern Jordan dated to about 4200 years ago. I know this because I upgraded to the Big Y, which tests SNPs, looking at several million locations on the Y chromosome of each man.

One academic customer recently compared this new technology as the difference between looking into space with binoculars versus the Hubble Telescope.

I don’t know if you are familiar with your list of matches at the highest level you’ve tested for, either Y-67 or Y-111. If you are, you should recognize my name and the names of others who have taken the Big Y test.

You’ll see what you’ll gain by letting me upgrade your test for you and determining whether you are related to my line – probably between about 200 years and 500 years.

This might be the second time that I have written to you on this matter; can I presume if I don’t hear from you that you’re not really interested in the Y-DNA subject anymore?

Can I run the test so that I can see how closely we are related – at my expense? (Of course, you get to see how closely related we are, too).

Please reply to me and say “yes.” You don’t even have to put a 🙂 if you don’t want to.

I started this company and this industry over 20 years ago. I predict that you will be happy with the history of YOU that this upgrade will uncover.

Best,

Bennett Greenspan

As you can see, this email can easily be personalized further and adapted to matches at the 37, 25, and 12 marker levels – or even Family Finder matches, now that intermediate-range haplogroups are being reported.

What’s Next?

I’m going back to every one of the kits I sponsored or that represent descendants of one of my ancestors to review their matches again – focusing not just on the closest matches with common surnames, but also on locations – and specifically at lower matching levels. I’ll also be checking their Family Finder matches for male surname matches, or similar surnames.

As is evident from Bennett’s tests, an entire mine of diamonds is out there, just waiting to be unearthed by a Big Y test.

And to think that some people have been advising people to ignore 12-marker matches out-of-hand because they are “entirely irrelevant.” They aren’t – for two reasons.

  1. First, some early testers only tested to that level
  2. Second, because of the deeper history that Big Y tests from those matches will uncover

You can view your Y-DNA matches, upgrade your own Y-DNA test, or order a Big Y-700 test if you haven’t yet tested by clicking here. What’s your next step?

What’s Changed? –  Autosomal DNA Vendor Feature Changes Since the 23andMe Data Compromise

The 23andMe customer data compromise has reverberated throughout the technology industry, not limited to DNA testing.

The 23andMe compromise has provided the impetus for reflection and security and policy reviews at each DNA testing vendor.

That’s a good thing.

What has been and remains challenging is keeping track of which features have been disabled and are no longer available at each vendor as the vendors, including 23andMe, attempt to right themselves from this blow. Unfortunately, or maybe fortunately, we can’t just return to “business as usual.”

Some of these feature removals may only be paused, and a few have already returned. Some may never be resumed.

We don’t really know yet.

If you’re having trouble keeping track, welcome to the club.

The features that have been disabled are features that were exploited at 23andMe or could have been exploited by bad actors who signed on “as you,” exposing not only your data but that of your matches in one way or another.

To be very clear, there was no data leak or compromise at any other vendor, but some other vendors provide(d) similar features for their customers. Every vendor offering DNA testing to genealogists had to stop, pause, and reevaluate their security measures. That’s exactly what they should have done. Genetic genealogy is a team sport where compromising one person’s account exposes at least some information about thousands more individuals.

Every company has proceeded somewhat differently based on how their features work.

I’ve compiled a chart listing the four primary vendors alphabetically, with affected features.

The Scorecard

In this chart, “Not available” means the feature was available before the 23andMe incident but is not currently available.

Feature 23andMe Ancestry FamilyTreeDNA MyHeritage
Two-factor Authentication (2FA)[1] Required Required Will be required for project administrators and available for all users[2] Will be required soon.

Filter matches by ethnicity Never was available Never was available Never was available Not available

 

Accepts 23andMe DNA file uploads Not applicable Never was available Paused Not restricted but not available because 23andMe does not currently allow the download of your raw data file

Other features remain unchanged, so they are not mentioned.

I think I accounted for everything that has changed, including some features already resumed at MyHeritage.

23andMe has not stated if or when they will return any of the functionality that has been removed.

FamilyTreeDNA plans to return their paused features after 2FA has been implemented in early 2024.

Please note that this information may change at any time.

[1] There has been a great deal of gnashing of teeth surrounding 2FA and how it’s implemented at each vendor. If you experience issues, please contact the vendor in question.

[2] At FamilyTreeDNA, testers utilize a kit number as their username, not their name or email. No place is the kit number publicly associated with the user’s name. In the 23andMe breach, the user’s email and passwords had been exposed in earlier breaches, so the hacker simply tried the same username and password at 23andMe, with great success. That scenario cannot occur at FamilyTreeDNA because the username is not their email address, which is why 2FA is not required for users. Administrators can select their username, so they will be required to utilize 2FA soon.

[3] This means information about your DNA matches other than your matching segments, such as email address, maternal or paternal matches, notes, surnames, and other relevant information.

[4] Matching segment information for each match. Used for triangulation, ancestor identification, and at DNAPainter.

[5] Shared matches between you and another match.

[6] Ancestry has recently announced that they will require a membership to view several features available with a DNA test, including Common Ancestors (ThruLines), Notes, Trees, Groups, and filtering matches by unviewed status. These features will not be available to DNA testers without an Ancestry subscription.

[7] Available if maternal/paternal matching is enabled. When matching, each individual who matches the tester and other testers and is bucketed on the same maternal/paternal side will triangulate on at least one segment.

[8] This is to prevent data scraping if a bad actor gains access to your account.

[9] The 23andMe data was reported to have focused on both Jewish and Chinese customers
