RootsTech 2025 – The Year of Discover and the New Mitotree

Posted on March 15, 2025 by Roberta Estes

Last week, RootsTech was a whirlwind and full of discoveries – which, ironically, was the 2025 theme.

I always take you along with me and share the RootsTech experience, start to finish, so here’s my 2025 “feet on the ground” report.

I might, just might, have overcommitted myself. I taught the half-day DNA Academy, three more sessions, plus several other commitments such as book signings, get-togethers, and interviews.

One class, “DNA for Native American Genealogy,” was a live webinar from the floor of the expo hall. You can watch that here for free, if you’re interested.

Unfortunately, none of my other sessions were recorded, but I’ll see what other alternative options may be available to bring those to you.

Additionally, I did two book signings at the GenealogyBank booth, along with two other authors, Drew Smith and Sunny Morton. I’m sorry, I don’t have any pictures. I should have asked someone to take some.

There were long lines and books sold out. Still, you can order either of my books, The Complete Guide to FamilyTreeDNA – Y-DNA, Mitochondrial, Autosomal and X-DNA or DNA for Native American Genealogy, at Genealogical.com. Thank you to GenealogyBank for being so welcoming.

The book signing was particularly fun because people shared their success stories or their hopes of what they want to achieve. I met a couple of new cousins too! Even people waiting in line were helping each other with information about research resources.

I had created my “RootsTech plan” for sessions I wanted to attend, but I was only able to actually attend one of those. Several were happening at the same time as mine, or directly before or after. As a presenter, you arrive early to get set up and make sure everything is working correctly.

Then, after your session, attendees have questions and are interested in your topic, which is a good thing. So essentially, you can’t attend sessions either before or after your session either.

Before I share photos, I’d like to share something else.

It’s About the People

I have never attended RootsTech for the classes, although there are wonderful offerings – and I have enjoyed them immensely.

Having said that, for me, the best part of RootsTech is the people. People I know and love but never get to see – many of whom I met in-person at RootsTech initially. I get to meet my blog followers. I meet with or reconnect with friends and cousins from around the world. I am privileged to talk with people about their challenges and their victories – when they’ve broken through a brick wall using DNA that they could never have otherwise achieved. People collaborating and helping each other. It’s all beautiful.

The reason I started blogging in the first place, and the reason all 1750 articles are free, is because I wanted to help people do just that – confirm ancestors, find ancestors, and connect with their fsmily.

My cousins that I’ve met through genealogy are some of my closest friends and closest family members. Outliving everyone is a mixed blessing but it makes me extremely grateful for my various cousins since all of my siblings and close family, with the exception of the next generation, have transitioned to the land of the ancestors.

So, yea, for me, RootsTech is about connecting and reconnecting with the people.

That’s also why I never get anything done because I’m always talking with someone.

Additionally, this particular RootsTech was a celebration.

Mitotree Release

Just a few days before RootsTech, the Million Mito Team at FamilyTreeDNA released the brand new Mitotree, 5 years in the making, reconstructing the tree of humankind to reflect our combined heritage more accurately.

At RootsTech 2020, I was honored to announce the Million Mito Project, and the new Mitotree initiative was born.

At some point, I will write about the deep, personal significance of the Mitotree for me, but for now, suffice it to say that there is something profoundly moving about rewriting the tree of humankind and in doing so, giving a voice to our ancestors from long ago. Yes, I know many of them are thousands or even tens of thousands of years old, but had they not survived, we would not be here today. Now we can identify who they are and that they lived.

Our amazing Dream Team has given life to our ancestors and said their names once again, even if their name is a mitochondrial DNA haplogroup. Four team members, Goran, Paul, me and Bennett were at RootsTech. Where else can you actually approach and speak with the actual scientists?

When I say RootsTech is about the people, I know that I am related to every single individual at RootsTech, it’s just a matter of how far back in time. So are you.

Just think about the significance of that for a minute.

Every. Single. Person.

The other end of the mitochondrial DNA spectrum is genealogy, of course, and the new Mitotree with it’s haplotype clusters brings mitochondrial DNA results into the genealogical timeframe. In future articles, I’ll be writing about each one of the new tools, what they mean, and how to use them.

Dr. Paul Maier, lead scientist doing most of the hard science behind Mitotree, had the much-deserved honor of introducing the Mitotree to genealogists at RootsTech.

I’m not sure the audience understood they were witnessing history unfold, but they clearly were. We needed a drum roll and some balloons!

This wasn’t like most vendor announcements of a new product or feature – this was a major scientific achievement that led to genealogical benefits.

In celebration, I asked my friend to make double helix zipper pulls so that I could give them to colleagues, friends and cousins that I ran into at RootsTech. It’s my way of celebrating and sharing the joy!

Five years is a very long time to work on a project. The Mitotree is a massive accomplishment. Every customer at FamilyTreeDNA who has taken the full sequence test received their new haplogroup either the week before or during RootsTech, AND, the second updated version of the tree was released too.

While this is truly wonderful, the true highlight is the testimonials – seeing how Mitotree is actually helping people break through their brick walls.

Here’s just one.

Breathless Testimonial

I’m going to try to convey this exactly as it happened.

A lady that I don’t know literally runs up to me in the hallway. This isn’t unusual. She was so excited that what she said was one long breathless sentence, which I’m going to try to reconstruct here, although I’m adding a bit of punctuation. I also can’t remember how many “greats” were attached to the “grandmother,” but you’ll get the idea.

Roberta, Roberta, I’m so excited – I just wanted to let you know – I found my ancestor using mitochondrial DNA. I got my new haplogroup and I had like 47 matches before but now they are clustered together so I could focus…and there were three matches in my cluster…and one of them had an EKA but the other didn’t…so I built out the EKA matches’ tree and guess what??? They were from the same place and then I found that her great-great-grandmother’s sister is my great-great-grandmother but she had her surname so now I have more generations too. OMG I ‘m so excited I could never have broken through this wall without mtDNA because I had no surname. This is THE MOST CONSEQUENTIAL DNA TEST I’VE EVER TAKEN, and I’ve taken them all. Thank you, thank you!

And with that she quickly hugged me and ran off to something she was obviously late for.

I never got to say one word, which was fine, but I stood there with tears in my eyes, thinking to myself, “This – this is what it’s all about.”

It doesn’t get better than this!

I want to hear your stories too. I just scaled my fourth brick wall last night using the new Mitotree and mtDNA Discover features.

RootsTech Week

RootsTech week started early for me – as in leaving the house at 3 AM Sunday. I fly on Sunday because the flights are cheaper and because the pre-conference meetings and events begin on Monday.

We took off into the dawn, jetting our way westward through the azure blue sky.

I have never gotten over the majesty and beauty of the Rocky Mountains.

And then, of course, the Great Salt Lake, for which Salt Lake City is named.

Looking at the Salt Palace across the street from the Marriott hotel. The silver building is the new Hyatt which is attached to the conference center behind the windmills which extends another very long block to the right, out of view. The mountain range is visible in the distance, and the beautiful sunset.

Speaking of the Marriott hotel, several people have asked if it was any better this year, and if I got trapped in the fire exit again, like last year.

No, I didn’t get stuck because I didn’t tempt fate again. It looked just the same though, so I’m presuming nothing has changed. Furthermore, there was no heat in my room, so they gave me a space heater and a pass to the concierge level – which they did not do last year.

That was kind of them, but food ran out, and there was only one poor server in the restaurant. I’m not even going to mention the nauseating thing that happened with my food. Let’s just say I’m not picky, but I will NEVER eat there again, and that makes it particularly difficult because there’s very little close by, especially when you’re exhausted.

I’m hoping that RootsTech will negotiate someplace different for speakers in the future. I’ve stayed in a lot of Marriotts and most of them are just fine. I have never had issues like this with any of them, let alone repeat issues year after year.

The good news is that we’re not there for the hotel, and the fun began on Monday.

Monday

My interviews began on Monday morning with “Mondays with Myrt” at the FamilySearch Library, which you can view here beginning about 16 minutes.

Mondays with Myrt is a RootsTech tradition and Myrt incorporates people present in person and tuning in virtually as well. Left to right, Kirsty Gray from England, John Tracy Cunningham, me and Myrt. Kirsty had a huge breakthrough that she shared with us just a few minutes after it happened.

I met John at the ECGGS Conference last October. He’s one of the few people I know whose 8 great-grandparents were born in the same county. I’m so jealous. Mine were either born in or first generation immigrants from four countries.

Sometimes the broadcast waiting area is just as much fun as the actual broadcast – in part because it’s the first day of RootsTech week and everyone is so excited to see their friends that they haven’t seen in forever. Call is a reunion!

Do Kirsty Gray and I look like we’re about to get into mischief?

Behind me is the first group of folks to be interviewed.

Pat Richley-Erickson, aka Myrt, Cheryl Hudson Passey, Laura Wilkinson Hedgecock, and Jenny Horner Hawran.

This is the livestream room at the FamilySearch Library. The waiting area for the next group is to the right, and the three presently being interviewed are sitting on the left beside Myrt.

For those who know Gordon, aka Mr. Myrt, he’s coordinating interviewees outside the livestream room. His job is herding cats and he’s the nicest cat-herder you’ll ever meet!

Pre-RootsTech Library Research

I love the FamilySearch Library. It feels like coming home to me.

So many passionate genealogists at every level – learning and searching. Lots of volunteer helpers available, too.

Normally, I create a research plan for the library, but I had been so utterly slammed between preparing my several RootsTech sessions and the Mitotree release that I hadn’t really been able to prepare anything.

I did, however, have a group of ancestors in mind that settled in the Oley Valley in Pennsylvania, so I decided to focus on the Berks County books.

I won’t bore you with the details, but among other things, I found confirmation that the Hoch surname is also the same as High and Hoy, which explains some very confusing Y-DNA results. So even though I didn’t get much productive time there, I did find something very useful in the land records.

I also ran into cousins and friends, of course, which is why I didn’t get more actual research done.

I knew Judy Nimer Muhn, at left, was going to be at RootsTech as a speaker, and I knew we connected through Acadian lines, but we never took the time to really piece together that puzzle.

My cousins, Mark and Manny were also coming for RootsTech, and to visit the library, for the first time. Mark, Manny and I visited Nova Scotia together in the summer of 2024, chasing our ancestors.

You know, fate is a funny thing.

We all descend from Acadian, Francois Savoie who was born about 1621 in France, but settled in Acadia, today’s Nova Scotia. Mark, Manny and I knew that we are cousins through Francois, but Judy and I did not. Mark, Manny and I ran into a local historian, Charlie Thibodeau, the Acadian Peasant, last year, outside of Port Royal. It just so happened that he was taking another couple to see the remains of the Savoie homestead deep in the salt marshes at BelleIsle.

We asked if we could join them, and Charlie was kind enough to include us. It was a long, brutally hot, tick-infested hike through the swamp, but oh so worth it!

We also found the well, located between three homesteads.

The year before, Judy had been in the same place in Nova Scotia, found the same man, Charlie, at the BelleIsle Hall Acadian Cultural Centre, and he had taken her to the remains of the same homestead.

And here we all four are in Utah.

What are the chances?

Needless to say, we had a LOT to talk about, and still do. Unfortunately, I wasn’t able to get to Judy’s talk, but Mark and Manny attended.

I ran into Katy Rowe-Schurwanz, the FamilyTreeDNA Product Manager at the library too, and look what she’s wearing – a mitochondrial DNA scarf. How cool is that!

The rest of Tuesday and most of Wednesday morning were spent trying to update my several presentations to reflect newly released information by various vendors and practicing the timing of the presentations. I had another interview, and more people were arriving.

I found time to visit Eva’s Bakery about 3 blocks from the Salt Palace. If you’re ever in Salt Lake City, Eva’s is a must! Lunch is wonderful, and so are their French pastries.

Wednesday is “tech prep” day at RootsTech, along with speaker instructions and then the Speaker Dinner.

Steve Rockwood, President and CEO of FamilySearch always delivers an inspirational message and this year did not disappoint.

If you’ve wondered about RootsTech conference stats, they provided this information. I can’t even imagine trying to coordinate all of this – and that’s not including the vendors, expo hall, technology in the presentation rooms, food, security and so much more.

Last year, in 2024, the final attendance numbers were more than 16,000 people in person and 4 million virtual attendees. I noticed a few days ago that there were more than half a million people participating in Relatives at RootsTech, which is still live until April 12^th.

On Wednesday evening, after the Speaker’s Dinner, vendors in the Expo Hall were putting the final touches on their booths and preparing for the thousands of excited genealogists who would descend Thursday morning.

Discover

This year’s RootsTech theme was “discover” and attendees were greeted with this display just inside the door.

Attendees listed their discoveries on Post-its and could either post them on the board or plastic boxes, or on the green tree.

I placed my discovery from the day before at the library on the Rootstech tree.

Some people place their wishes here, kind of like a technology wishing well.

I couldn’t help but think of the new Mitotree, now forever green and growing, so I posted a second discovery, “Mitotree.”

Thursday – Opening Day

For those who don’t know, the Salt Palace Convention Center is two lengthy blocks long, a block wide, and two or three stories high, depending on whether you are in the front or rear portion. In other words, it’s massive and you need a map!

The huge Expo Hall with vendors is located in the center on the first floor and vendors have aisle addresses. The show floor is always very busy, and this year was no exception. One of the things I love is that spontaneous conversations just spring up between people who often find commonalities – common ancestors, common locations, and more. People compliment each other and join others at tables. It’s like a big family gathering of sorts.

I always try to walk the entire Expo Hall, because I really enjoy seeing the vendors and their wares, but this year, I never actually had enough time to traverse all the aisles. I took several pictures as I was passing through and running into people, but not nearly enough. I know I missed a lot, but there just wasn’t enough time and I arrived at RootsTech already tired.

However, the energy of RootsTech is like no place else and just infects you.

It’s like you can’t drink from the genealogy firehose fast enough!

Let’s Take a Walk

Ok, come along on a walk with me.

Left to right, Lianne Kruger, a speaker, and Courtney, in the FamilyTreeDNA booth. I believe they said they are cousins.

Daniel Horowitz, genealogist extraordinaire, in the MyHeritage booth. More about MyHeritage’s announcements shortly.

Geoff Rasmussen in the Legacy Family Tree Webinars booth. For those who don’t know, there’s lots of good material at Legacy, and the freshly recorded webinars are always free for a week.

Several vendors offer booth talks, including MyHeritage. I love their photo tools and use their site in some capacity almost daily.

One of the RootsTech traditions is ribbons. Collect one, collect ‘em all. Liv’s ribbons almost reach the floor. I think she wins!

Selfies are also a RootsTech tradition. Me, here with Jonny Perl of DNAPainter fame. I owe Jonny an apology as he asked me if I had a minute, and I had to say no because I was on the way to one of my own classes. I never got back to his booth to view his new features. Sorry Jonny – don’t take it personally!

Jonny released a new Ancestral tree version titled Places, so take a look here at his blog. I need to go look at my ancestors Places.

You’ll find this new feature under Ancestral Trees, Places. These are my most recent 8 generations. Just think of all those brave souls who climbed on a ship and sailed for the unknown. Check this feature out and have fun.

In a booth talk, Dave Vance, Executive Vice-President and General Manager at FamilyTreeDNA is speaking about the three types of DNA, which are, of course, Y-DNA, mitochondrial and autosomal DNA – all useful for genealogy in different ways.

Dave is explaining how in-common-with matches, also known as shared matches, operate with the chromosome browser. You can use the chromosome browser, shared matches, the new Matrix Tool, and download your match segment information at FamilyTreeDNA, a combination of features not available at any other vendor.

WikiTree, a free a moderated one-world-tree is one of my favorite genealogy tools. One of their best features is that you find your ancestor, and in addition to lots of sources, their Y-DNA, mitochondrial DNA, and those who are related autosomally are listed. Here’s my grandfather, for example.

Several DNA connections are listed. The further back in my tree, the more DNA connections are found, becuase those ancestors have more descendants.

WikiTree volunteers were wandering around taking pictures of “WikiTreers” holding fun signs.

Paul Woodbury, a long time researcher with Legacy Tree Genealogists, who specializes in DNA. I don’t take private clients anymore, and regularly refer people to Legacy Tree.

Me with Janine Cloud taking our annual RootsTech selfie. Janine, the Group Projects Manager at FamilyTreeDNA and I co-administer one of those projects and accidentally discovered a few years ago that we are cousins too. How fun is this!!!

I wanted this shirt, but by the time I got back to the booth, it was too late. I’m going to order it online from Carlisle Creations, in case you want one too. This is so me.

Land records are critically important to genealogists. Rebecca Whitman’s class was about plotting land plats. What she’s holding is a surveyor’s chain. You’ve read about chain carriers? This is what they carried to measure land boundaries – literally metes and bounds. Some of my best discoveries have been thanks to land records.

The only session I actually got to attend was Gilad Japhet’s “What’s New and Exciting at MyHeritage.” For those who don’t know, Gilad is the founder and CEO of MyHeritage and it’s always great to hear about the new features straight from the top executive who is, himself, a seasoned genealogist. That’s why he started MyHeritage in the first place – 22 years ago in his living room.

Gilad had several wonderful announcements, but the one I’m most excited about is their new Cousin Finder. Cousin Finder finds and reveals cousins who are DNA candidates if they have not yet taken a DNA test.

I’ll be writing more about the MyHeritage announcements soon, but you can read their blog about Cousin Finder now, here, and their Roundup here about the rest of their announcements!

My Last Class – Reveal Your Maternal Ancestors & Their Stories

My last class at the end of the final day of RootsTech was “Reveal Your Maternal Ancestors & Their Stories – Solving Mitochondrial DNA Puzzles.”

Had I tried to coordinate this presentation with International Women’s Day, I could never have done it, but fate winked and here I was.

I’m often asked what it’s like from the presenters’ perspective. This is one of the smaller ballrooms. My earlier sessions were in larger rooms, maybe 3 times this size. I took this picture about 15 minutes before the session started as people were beginning to drift in.

The amazing RootsTech techs had me wired up to microphones and had verified that the audio and video equipment was working correctly, so now it was just waiting.

My cousin, John Payne, who co-administers the Speaks surname project with me, came by and took this great picture of the two of us. We’ve made huge inroads connecting the various Speake(s) lines in America, plus finally proving our home village in England, thanks to the Big Y-700 test, followed by church records. All is takes, sometimes, is that one critical match.

As I sat there, waiting to begin the mitochondrial DNA session, I couldn’t help but reflect upon all of the women who came before me and how fortunate I was to have been in the right place at the right time to be a member of the Million Mito team.

These are my direct matrilineal ancestors who give me, and my daughter, pictured at left, their mitochondrial DNA. I felt them with me as I sat there, waiting.

The woman at furthest right, Barbara Drechsel (1848-1930), immigrated to Indiana from Germany as a child with her parents in the 1850s. Before her came thousands of generations of women with no photos, of course, and no names before Barbara Freiberger, another eight generations earlier, born about 1621 in Germany.

Before that, which was before church and other records, prior to the 30 Years War, this lineage came from Scandinavia where some of my exact matches are still found today.

Before beginning, I said a positive affirmation and thanked my ancestors – so very honored to introduce them. I know they were proud of me, a member of the team that opened the door to the distant past. I wouldn’t be here if not for every one of their lives.

In this session, I would discuss, for the first time ever, the new Mitotree and my/our connection to all of humanity some 7000 generations ago, more or less.

The mutations we carry over those generations form an unbroken chain of breadcrumbs, connecting us to mitochondrial Eve who lived about 145,000 years ago. We revealed that breakthrough finding in the Haplogroup L7 paper, published in 2022.

I’m still in absolute awe that we have been able to both reach that far back in time AND, at the same time, make the newest haplogroups and haplotype clusters genealogically relevant. I will write more about that soon, but for now, I wrote about the Mitotree release here and you can find articles by Katy Rowe-Schurwanz here and here.

I’m very excited about my new mitochondrial DNA results for my ancestral lines that I track and have already made headway on several.

I’m not the only one.

Not only was I excited about my results, many other people have had breakthroughs too, including Mark Thompson, one of our genealogy AI experts who also spoke at RootsTech. I particularly love his AI generated image.

If you haven’t yet, check your mitochondrial DNA results.

It’s a Wrap

Another year done, another RootsTech under our belts. Hopefully everyone is over the “conference crud” by now and are busily applying their newfound knowledge.

You can view either live-cast sessions or RootsTech webinars, here.

I saw a meme posted sometime during the conference that coined the term “exhausterwhelmulated,” a combination of exhausted, overwhelmed and overstimulated at the same time.

I added exhilarated and elated to the mix and asked ChatGPT to draw me a picture of someone at a genealogy conference feeling those simultaneous emotions.

ChatGPT titled this request “Genealogy Conference Overload,” which made me laugh.

The first two attempts looked like the person had a headache, which I fully understood, so I asked ChatGPT to make the person look happy to be there.

This person, carrying a coffee like I often do, looks like they have just discovered the great irony that they have chased the wrong ancestor for some 20 years – with “laugh or I’ll cry” mania being their overwhelm “go to” in that minute.

This one made me laugh too!

Yes, indeed, I think every single one of us, especially at RootsTech, has experienced this exact adrenaline-fueled emotion.

We leave with a VERY long to-do list, exhausted but full of anticipation and buoyed by excitement. Filled with so much gratitude for our cousins and fellow genealogists, the speakers, vendors, DNA to solve thorny problems, new tools and records, FamilySearch who sponsors RootsTech itself and their amazing employees, plus the legions of the volunteers who make it all work.

Thank you! Thank you! Thank you!

The Big Y-700 Test Marries Science to Genealogy

Posted on July 11, 2024 by Roberta Estes

Recently, one of my long-time friends and project co-administrators asked me a simple question.

What do the FamilyTreeDNA Big Y-700 test and the Time Tree tell us when we have genealogy trees provided by testers?
What does the Discover Time Tree tell us that’s different, and how do we reconcile the Time Tree and genealogy?

Those are great questions.

Sometimes, I get so buried in the details of genetic genealogy that I neglect the obvious, so I’m writing this article for my co-admin and anyone else with the same questions.

Time Tree Versus Genealogy Question

Of course, as a genealogist, my first answer would be that we always need to be cautious about user-provided trees. Even when the genealogy is accurate, that’s no guarantee there wasn’t a biological disruption that caused the genetic line not to be the same as the surname line.

Almost every lineage has examples of people whose genealogy was “off” or misattributed paternity occurred someplace upstream, meaning that someone carries the surname but does not descend from that biological lineage.

However, relative to DNA projects, the Big Y-700 tests provide one very important feature that STR testing does not and cannot do.

The Big Y-700 test creates a genetic tree, in conjunction with other testers, which provides scientifically calculated dates when branches of the genetic tree were formed.

The genetic tree should align, at least closely, with testers’ genealogical trees.

In other words, if their genealogy is accurate, testers “should” fit in (or at least near) the appropriate places on the branches of the genetic tree.

Furthermore, for people trying to sort out their actual branch in the tree, the Big Y-700 test is MUCH MORE reliable than the earlier STR (short tandem repeat) tests that are prone to random and back mutations. At one time, STR tests were all that was available, but now, SNPs have been added to our arsenal. SNPs (single nucleotide polymorphisms) are extremely stable and reliable mutations.

I’m getting ready to record a new Y-DNA webinar, and I’m giving you a sneak peek of a couple of my slides here. I’ll publish an announcement when the webinar is available.

STRs Versus SNPs

Historic Y-DNA testing tested only a limited number of STR locations. That test reported the number of repeats at a specific genetic location on the Y chromosome. Today, the 37, 67, and 111 marker STR tests are still available to purchase.

What are the major differences between the two types of tests, and why would someone purchase one over the other?

If you purchase one of the STR tests, you purchase testing at a specific number of locations, such as 37, 67, and 111. The Big Y-700 test includes at least 700 STR locations, but the specificity of the Big Y-700 SNP testing replaces most of the STR test results in terms of lineage definition.

SNP mutations, when discovered in more than one man in a particular haplogroup lineage, are then named as haplogroups. That mutation is then found in each directly descended male in that line.

	STR – 37, 67, 111	Big Y-700 (STRs & SNPs)
Tests	A limited number of repeat STR markers – Big Y guarantees 700+	NGS scan targets ~ 25 million locations
Focus	Comparatively short genealogy timeframe	All-inclusive – recent genealogy plus older to ancient
Includes	Can upgrade to Big Y-700	Includes STR tests, separate matching, Globetrekker, Discover, and more
Tree	Genealogy, customer provided	Genetic Tree – Group Time Tree coordinates with genealogy if provided
Tools	STR tools	STR tools plus SNP tools & robust Discover
Haplogroup	Estimated based on STR values	Confirmed to the most granular level possible – evergreen
Useful When	Exclusion testing, less costly, entry-level	Discover provides lineage, ancient DNA, TMRCA, and more
Matching	STRs only	STR plus Big Y – both can be useful
Trees	Customer provided genealogy	Time Tree, Group Time Tree, Block Tree, Classic Tree + 1 more soon

Put simply, the STR tests are now entry-level. Once you see what the Big Y-700 provides, you’ll absolutely want to upgrade to that test. Most of the time, if I know I’m testing someone from the correct line, I just purchase the Big Y-700 out the gate. If I’m not sure I’m testing the correct lineage, I’ll purchase the STR test first to make sure they match the correct lineage before upgrading to the Big Y-700.

Discover

The Discover tool was introduced to provide additional information to Big Y testers and others seeking haplogroup information. STR results can only predict a relatively high-level haplogroup, usually a few thousand years ago, while the Big Y-700 provides testers with an extremely granular haplogroup – usually decades to a few hundred years ago. Often, living men that span 2 or 3 descendant generations (grandfather, father, sons) discover that they have their own haplogroup branch on the tree of mankind!

However, if no one else from your line has tested in hundreds of years, Discover can only work with available information.

Let’s take a quick look at the Estes Group Time Tree.

Estes Project Group Time Trees

Group projects have Group Time Trees. You can view the Estes surname project, here. You can find a project for any surname by either googling “<surname> DNA Project” or scrolling to the VERY bottom of the FamilyTreeDNA main page.

If you’re signed into FamilyTreeDNA, you can also find projects in the top banner.

Once you’re on the project page, you’ll see an option for DNA Results (assuming the administrators have not made the project entirely private.)

Click on the DNA Results link and select Y-DNA.

Next, you’ll see “Group Time Tree.”

Group Time Tree Display

What appears next depends on how the project administrators have grouped the project participants.

I’ve grouped the Estes project by genealogical line, with the exception of a couple of people who carry the Estes surname but have experienced an adoption or other unknown parental event in their Estes lineage.

In some cases, there are simply two same-name lineages that were never from the same biological line. Unfortunately, occasionally they settle in the same place, making the genealogy difficult. Even worse, until Y-DNA testing came along, there was often no way to know they were two different families.

This situation is actually where the Big Y-700 test shines.

The Group Time Tree shows the genetic tree scientifically constructed from the SNP results of the Big Y-test results of the testers, at left. At right you’ll see the surnames of the testers along with their Earliest Known Ancestor (EKA) if they have entered that information.

Initially, you don’t even realize you’re actually looking at two types of information merged together. This display allows testers to see the genetic branching tree structure, at left, which is reflective of their actual genealogy, at right.

You can see that the birth year of Sylvester Estes, entered by a tester with haplogroup R-BY482, is 1622. Please note, there’s a typo. Sylvester was born in 1522, NOT 1622. This is a perfect example of what I meant by tree information sometimes being inaccurate and it’s very important when trying to correlate the genetic tree and the user-provided genealogy.

We discovered that R-BY482 (red profile above, at left) is an Estes “signature” haplogroup for the Estes line originating in Deal, England, with three other haplogroups that formed in descendant generations. We know this because every descendant from this line has this mutation.

R-BY490 was formed between Sylvester’s son Robert Estes, born about 1555, and his son, born about 1600, also named Sylvester. We know this because all of the descendants of Sylvester (born circa 1600) carry this mutation, but Robert’s son, Robert, born in 1603, does not.

The genealogy portion of the Group Time Tree, above, doesn’t reveal that information because testers either don’t know their genealogy that far back or perhaps listed an earlier known ancestor, such as Nicholas, born in 1495.

I created a spreadsheet tracking the Big Y-700 testers of the descendants of Nicholas Estes, along with their descendant haplogroups.

We know that Robert, born in 1555, carries R-BY490 because both of his sons, Abraham and Richard, inherited that mutation, seen with green arrows.

However, this calls into question the associated genealogy because if Robert, born in 1603, descended from Robert, born in 1555, he too would have the mutation R-BY490 since Robert’s other two sons do. Note that the user-provided birth year typo of 1622 which should be 1522 is a century off – enough to be within the genetic band haplogroup birth band – but impossible for the genealogy table.

There is one other possibility: kit 166011, the descendant of Robert born in 1603, could have taken the earlier Big Y-500 test and never upgraded to the more powerful Big Y-700. That’s too much detail for this article, but the discrepancy between the genetic tree and the genealogy tree alerts us that additional research is warranted. The genealogy submitted for tester 166011 confirms that, indeed, 1622 is a typo.

There are no other descendants of known sons of Nicholas or Sylvester born in 1522 to test, but perhaps another will surface one day.

You can see that the more testers in any particular line, the more granularity we can achieve.

The Genetic Tree

How close is the genetic tree to the genealogical tree that has been confirmed?

We know that Sylvester was born in 1522, and his father Nicholas in about 1496. The scientifically calculated creation date of R-BY482 is 1493, just 3 years before the birth of Nicholas. Based on this, there’s a good chance that this mutation occurred between Nicholas’s unknown father and him, or perhaps between Nicholas and Sylvester.

You can view the scientific details of any haplogroup in Discover.

Discover’s BY-482 scientific details page shows its creation date range.

Marriage

You can see that the scientifically created tree and the genealogy information are both important.

In fact, the combination of both allowed us to identify the correct branch of a Wilbur man who matches Estes men but doesn’t know where he fits in the tree.

His haplogroup placed him definitively on the more recent R-BY154784 branch, and his autosomal results then confirmed his specific path of descent because he matches descendants of three generations of Estes men’s wives, showing that his branch descends from Joseph Estes and his wife Ritty Lee, through son Chism, on down to our tester. In this case, autosomal DNA results provided a boost-assist to the genealogy, which helped identify the generation that the Y-DNA haplogroup R-BY154784 actually formed.

This also informs us that Joseph Estes, born in 1780, carried haplogroup R-BY154784 because both of his sons have it. If Joseph hadn’t had that mutation, then both of his sons couldn’t have inherited it.

Therefore, the mutation that formed haplogroup R-BY154784 had to occur between Moses, born in 1711, and John, born in 1732. We know that because Moses’s other son’s descendants do not have that haplogroup.

The more descendants of any ancestor that test, the more specific and accurate the descendant haplogroup formation dates will be.

The marriage of genetic trees and genealogy is powerful indeed.

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

Posted on January 21, 2024 by Roberta Estes

“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:

Who are we?
Where did we come from?
Where were we before we were there?
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

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 9^th 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 2^nd 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.

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

FamilyTreeDNA 2023 Update – Past, Present and Future

Posted on December 11, 2023 by Roberta Estes

At the FamilyTreeDNA International Conference on Genetic Genealogy, held November 3-5 in Houston for group project administrators, product and feature updates were scattered across both days in various presentations.

I’ve combined the updates from FamilyTreeDNA into one article.

I’ve already written two articles that pertain to the conference.

15^th Annual FamilyTreeDNA Conference for Genetic Genealogy – Reunion, Reception and Keynote

FamilyTreeDNA has already begun rolling the new Y DNA haplogroups from Family Finder autosomal tests, which I wrote about here:

FamilyTreeDNA Provides Y DNA Haplogroups from Family Finder Autosomal Tests

I still have at least two more articles to publish from this conference that was chocked full of wonderful information from a wide range of talented speakers.

Past, Present, and Future with Katy Rowe-Schurwanz

Katy Rowe-Schurwanz, FamilyTreeDNA’s Product Manager, provided an update on what has been accomplished in the four and a half years since the last conference, what’s underway now, and her wish list for 2024.

Please note the word “wish list.” Wish list items are NOT commitments.

Recent Milestones

A lot has been happening at FamilyTreeDNA since the last conference.

Acquisition and Wellness Bundles

As everyone is aware, at the end of 2020, myDNA acquired Gene by Gene, the parent company of FamilyTreeDNA, which included the lab. As a result, the FamilyTreeDNA product menu has expanded, and wellness bundles are now available for FamilyTreeDNA customers.

If you’re interested, you can order the Wellness product in a bundle with a Family Finder test, here.

You can add the Wellness product for $39 if you’ve already tested.

New TIP (Time Prediction) STR Report

Did you notice that the old TIP report for Y DNA STR markers was replaced with an updated version several months ago?

To view the new report, sign on and select your Y DNA matches. At the far right of each match you’ll see these three icons representing a pedigree chart, notes, and the TIP (Time Predictor) report.

The updated TIP report includes wonderful new graphs and age estimates for each match category, which you can read about, here. Each category, such as 67-marker matches, has time estimates in which a common ancestor might have lived at each possible genetic distance.

Math is our friend, and thankfully, someone else has done it for us!

Please note that the Big Y SNP dates are MUCH more accurate for a variety of reasons, not limited to the instability and rapid mutation rate of STR mutations.

MyOrigins3

MyOrigins3, FamilyTreeDNA’s ethnicity offering, added over 60 new reference populations for a total of 90, plus chromosome painting. You can read about MyOrigins features here, and the white paper, here.

This is one of my favorite improvements because it allows me to identify the segment location of my population ancestries, which in turn allows me to identify people who share my minority segments such as Native American and African.

Due to a lack of records, these relationships are often exceedingly difficult to identify, and MyOrigins3 helps immensely.

Additional Releases

Additional products and features released since the last conference include:

Family Finder improvements include a User Interface (UI) update, matching changes, and loading improvement. You can read the new Family Finder matching white paper, here.
Y DNA match pages received a UI update, too.
Lots of information buttons and boxes were added on many pages.
Many new and updated articles in the Help Center, here.

Discover

Released in July 2022, Discover is the amazing new free product that details your ancestor’s Y DNA “story” and his walk through time and across the globe.

In the past 18 months, all of the Discover features are new, so I’m only making a brief list here. The great thing is that everyone can use Discover if you know or can discover (pardon the pun) the haplogroup of your ancestral lines. Surname projects are often beneficial for finding your lineages.

Haplogroup Story includes haplogroup location, ages derived from the earliest known ancestor (EKA) of your matches, and ancient DNA samples. Please be sure you’ve entered or updated your EKA, and that the information is current. You can find instructions for how to update or add your EKA here.
A recent addition to the haplogroup story includes Haplogroup Badges.
Country Frequency showing where this haplogroup is found with either a table view or an interactive map
Famous and infamous Notable Connections, including Mayflower passengers, Patriots from the American Revolution, US presidents, royal houses, artists, musicians, authors, pirates, sports figures, scientists, and more.

If you know of a proven connection to a notable figure, contact customer support and let them know! Notable connections are added every week.

One famous Discover connection is Ludwig von Beethoven which resulted from a joint academic study between FamilyTreeDNA and academic researchers. It’s quite a story and includes both a mystery and misattributed parentage. You can see if you match on Discover and read about the study, here.

Updated Migration Map, including locations of select ancient DNA sites
The Time Tree, probably the most popular Discover report, shows the most current version of the Y DNA phylotree, updated weekly, plus scientifically calculated ages for each branch. Tree node locations are determined by your matches and their EKA countries of origin. I wrote about the Time Tree, here.
Anticipated in early 2024, the EKA and block tree matches will also be shown on the Time Tree in Discover for individual Big Y testers, meaning they will need to sign in through their kits.
The Group Time Tree, visible through group projects, takes the Time Tree a step further by including the names of the EKA of each person on the Time Tree within a specific project. Information is only displayed for project members who have given permission to include their data. You can select specific project groupings to view, or the entire project. I wrote about the Group Time Tree here and here.
Globetrekker is an exclusive Big Y mapping feature discussed here, here, here, and here.
Ancient Connections includes more than 6,100 ancient Y DNA results from across the globe, which have been individually analyzed and added for matching in Discover. Ancient Connections serve to anchor haplogroups and provide important clues about matches, migration paths and culture. New connections are added weekly or as academic papers with adequate Y DNA coverage are released.
Your Ancestral Path, which lists the haplogroups through every step from the tester back to Y Adam and beyond. Additional information for each haplogroup in your path includes “Time Passed” between haplogroups, and “Immediate Descendants,” meaning haplogroups that descend from each subclade. New columns recently added include “Tested Modern Descendants” and “Ancient Connections.”
Suggested Projects include surname, haplogroup, and geographic projects. Katy said that people joining projects are more likely to collaborate and upgrade their tests. You can also see which projects other men with this haplogroup have joined, which may well be projects you want to join too.
Scientific Details provides additional information, such as each branch’s confidence intervals and equivalent variables (SNPs). You can read more here.
Compare Haplogroups is the most recent new feature, added just last month, which allows you to enter any two haplogroups and compare them to determine their most recent common ancestral haplogroup. You can read about Compare Haplogroups, here.

Please note that the Studies feature is coming soon, providing information about studies whose data has been included in Discover.

You can read about Discover here, here, here, and here.

If you’re interested, FamilyTreeDNA has released a one-minute introduction to Y DNA and Discover that would interest new testers, here.

Earliest Known Ancestor (EKA) Improvement

Another improvement is that the earliest known ancestor is MUCH easier to enter now, and the process has been simplified. The EKAs are critical for Discover, so PLEASE be sure you’ve entered and updated your EKA.

Under the dropdown beside your name in the upper right-hand corner of your personal page, select Account Settings, then Genealogy and Earliest Known Ancestors. Complete the information, then click on “Update Location” to find or enter the location on a map to record the coordinates.

It’s easy. Just type or drop a pin and “Save.”

Saving will take you back to the original EKA page. Save that page, too.

Recommended Projects on Haplogroups & SNPs Page

You’re probably aware that Discover suggests projects for Y DNA testers to join, but recommended haplogroup projects are available on each tester’s pages, under the Y DNA Haplotree & SNPs page, in the Y DNA STR results section.

If there isn’t a project for your immediate haplogroup, just scroll up to find the closest upstream project. You can also view this page by Variants, Surnames and Countries.

This is a super easy tool to use to view which surnames are clustered with and upstream of your haplogroup. With Family Finder haplogroups being assigned now, I check my upstream haplogroups almost daily to see what has been added.

For example, my Big Y Estes results are ten branches below R-DF49, but several men, including Estes testers, have been assigned at this level, thanks to Y DNA haplogroups from Family Finder testing. I can now look for these haplogroups in the STR and Family Finder matches lists and see if those men are receptive to Big Y testing.

Abandoned Projects

Sometimes group project administrators can no longer function in that capacity, resulting in the project becoming abandoned. FamilyTreeDNA has implemented a feature to help remedy that situation.

If you discover an abandoned project, you can adopt the project, spruce things up, and select the new project settings. Furthermore, administrators can choose to display this message to recruit co-administrators. I need to do this for several projects where I have no co-admin.

If you are looking for help with your project, you can choose to display the button
through the Project Profile page in GAP. For non-project administrators, if you’d like to help, please email the current project administrators.

New Kit Manager Feature

FamilyTreeDNA has added a “Kit Manager” feature so that an individual can designate another person as the manager of their kit.

This new setting provides an avenue for you to designate someone else as the manager of your DNA test. This alerts FamilyTreeDNA that they can share information with both of you – essentially treating your designated kit manager the same as you.

If you’re the kit manager for someone else, you NEED to be sure this is completed. If that person is unavailable for some reason, and support needs to verify that you have legitimate access to this kit, this form and the Beneficiary form are the ONLY ways they can do that.

If your family member has simply given you their kit number and password, and for some reason, a password reset is required, and their email address is the primary contact – you may be shut out of this kit if you don’t complete this form.

Beneficiary Page

Additionally, everyone needs to be sure to complete the Beneficiary page so that in the event of your demise, FamilyTreeDNA knows who you’ve designated to access and manage your DNA account in perpetuity. If you’ve inherited a kit, you need to add a beneficiary to take over in the event of your death as well.

What is FamilyTreeDNA working on now?

Currently in the Works

Katy moved on to what’s currently underway.

Privacy and Security

Clearly, the unauthorized customer data exposure breach at 23andMe has reverberated through the entire online community, not just genetic genealogy. You can read about the incident here, here, here, and here.

FamilyTreeDNA has already taken several steps, and others are in development and will be released shortly.

Clearly, in this fast-moving situation, everything is subject to change.

Here’s what has happened and is currently planned as of today:

Group Project Administrators will be required to reset their password soon.

Why is this necessary?

Unauthorized access was gained to 23andMe accounts by people using the same password for multiple accounts, combined with their email as their user ID. Many people use the same password for every account so that they can remember it. That means that all a hacker needs to do is breach one account, and they can use that same information to “legitimately” sign in to other accounts. There is no way for the vendor to recognize this as unauthorized since they have both your user ID and password.

That’s exactly what happened at 23andMe. In other breaches, this information was exposed, and hackers simply tried the same username and password combination at 23andMe, exposing the entire account of the person whose account they signed in “as.” This includes all of their matches, genetic tree, shared matches, matches of matches, ethnicity, and segments. They could also have downloaded both the match list and the raw DNA file of the compromised account.

At FamilyTreeDNA, project administrators can select their own username, which could be their email, so they will be required to reset their password.

Additional precautions have been put in place on an interim basis:

A pause in the ability to download match and segment information.
A pause in accepting 23andMe uploads.

Administrators will also be required to use two-factor authentication (2FA.) To date, two of the four major vendors are requiring 2FA. I would not be surprised to see it more broadly. Facebook recently required me to implement 2FA there, too, due to the “reach” of my postings, but 2FA is not required of everyone on Facebook.

Please note that if you received an email or message that is supposedly from any vendor requiring 2FA, GO DIRECTLY TO THAT VENDOR SITE AND SIGN IN. Never click on a link in an email you weren’t expecting. Bad actors exploit everything.

Customers who are not signing in as administrators are not required to implement 2FA, nor will they be required to reset their password.

Personally, I will implement 2FA as soon as it’s available.

While 2FA is an extra step, it’s easy to get used to, and it has already literally saved one of my friends from an authorized hack on their primary and backup email accounts this week. Another friend just lost their entire account on Facebook because someone signed in as them. Their account was gone within 15 minutes.

2FA is one of those things you don’t appreciate (at all) until it saves you, and then, suddenly, you’re incredibly grateful.

At this point in time, FamilyTreeDNA users will NOT be required to do a password reset or implement 2FA. This is because customers use a kit number for sign-in and not a username or email address. I would strongly recommend changing your password to something “not easy.” Never reuse passwords between accounts.

I really, really want you to visit this link at TechRepublic and scroll down to Figure A, which shows how long it takes a hacker to crack your password. I guarantee you, it’s MUCH quicker than you’d ever expect.

Kim Komando wrote about this topic two years ago, so compare the two charts to see how much easier this has become in just two years.

Again, if you receive an email about resetting your password, don’t click on a link. Sign in independently to the vendor’s system, but DO reset your password.

FamilyTreeDNA also engages in additional security efforts, such as ongoing penetration testing.

New Permissions

Additionally, at FamilyTreeDNA, changes were already in the works to separate out at least two permissions that testers can opt-in to without granting project administrators Advanced rights.

Download data
Purchase tests

The ability to purchase tests can be very important because it allows administrators to order and pay for tests or upgrades on behalf of this tester anytime in the future.

Family Finder Haplogroups

FamilyTreeDNA has already begun releasing mid-level Y DNA haplogroups for autosomal testers in a staggered rollout of several thousand a day.

I wrote about this in the article, FamilyTreeDNA Provides Y DNA Haplogroups from Family Finder Autosomal Tests, so I’m not repeating all of that information here – just highlights.

The Family Finder haplogroup rollout is being staggered and began with customers on the most recent version of the testing chip, which was implemented in March of 2019.
Last will be transfers/uploads from third parties.
Haplogroups resulting from tests performed in the FTDNA labs will be visible to matches and within projects. They will also be used in both Discover and the haplotree statistics. This includes Family Finder plus MyHeritage and Vitagene uploads.
Both MyHeritage and Vitagene are uploaded or “transferred” via an intracompany secure link, meaning FamilyTreeDNA knows that their information is credible and has not been manipulated.
Haplogroups derived from tests performed elsewhere will only be visible to the user or a group administrator viewing a kit within a project. They will not be visible to matches or used in trees or for statistics.
Any man who has taken a Y DNA STR test will receive a SNP-confirmed, updated haplogroup from their Family Finder test that replaces their predicted haplogroup from the STR test.

Please read this article for more information.

New Discover Tools and Updates

Discover content continues to be updated, and new features are added regularly, creating an increasingly robust user experience.

Soon, group administrators will be able to view all Discover features (like Globetrekker) when viewing kits of project members who have granted an appropriate level of access.

Ancient and Notable connects are added weekly, and a new feature, Study Connections, will be added shortly.

Study Connections is a feature requested by customers that will show you which study your academic matches came from. Today, those results are used in the Y DNA tree, but the source is not detailed.

Anticipated in early 2024, the EKA and block tree matches will also be shown on the Time Tree in Discover for individual Big Y testers (not publicly).

Big Y FaceBook Group

FamilyTreeDNA has ramped up its social media presence. They launched the Big Y Facebook group in July 2023, here, which currently has just under 9000 members. Several project administrators have volunteered their time to help manage the group.

FamilyTreeDNA Blog

In addition, FamilyTreeDNA is publishing at least one blog article each week, and sometimes more. You can view or subscribe here. Some articles are written by FamilyTreeDNA staff, but project administrators and customers author other content.

Multi-Language Support

Translation of the main FamilyTreeDNA website and results pages to Spanish has begun, with more languages planned soon.

Paypal, Payments, and Gift Cards

Paypal has been added as a payment selection, along with a PayPal option that provides the ability to make payments.

Additionally, a gift card can be purchased from the main page.

Million Mito Project & Mitotree

Work on the Million Mito Project is ongoing.

The Million Mito Project was launched in 2020 as a collaborative effort between FamilyTreeDNA’s Research & Development Team and the scientific portion of the Genographic Project. I’m a team member and wrote about the Million Mito Project, here.

We’re picking up from where the Phylotree left off in 2016, analyzing 20 times more mtDNA full sequences and reimagining the mtDNA Haplotree. By examining more mtDNA data and applying the processes that allowed FamilyTreeDNA to build the world’s largest Y DNA Haplotree, we can also create the world’s largest Mitotree.

In 2022, the first update was released, authored by the Million Mito team, with the discovery of haplogroup L7. You can read about this amazing discovery rooted deep in the tree here, here, and here. (Full disclosure: I’m a co-author.)

Not only that, but “Nature Scientific Reports” selected this article as one of five named Editor’s Choice in the Mitogenomics category, here. In the science world, that’s a HUGE deal – like the genetic Emmy.

Here’s one example of the type of improvements that can be expected. Currently, the formation of haplogroup U5a2b2a reaches back to about 5000 years ago, but after reanalysis, current branches originated between 500 and 2,500 years ago, and testers are clustered more closely together.

This is SOOO exciting!!!

Just as Discover for Y DNA results was built one feature at a time, the same will be true for MitoDiscover. That’s my name, not theirs.

As the new Mitotree is rolled out, the user interface will also be updated, and matching will function somewhat differently. Specifically, it’s expected that many more haplogroups will be named, so today’s matching that requires an exact haplogroup match to be a full sequence match will no longer work. That and other matching adjustments will need to be made.

I can hardly wait. I have so many results I need to be able to view in a tree format and to place in a timeframe.

You can be included in this exciting project, learn more about your matrilineal (mother’s) line, and hopefully break down some of those brick walls by taking the full sequence mitochondrial DNA test, here.

After the new Mitotree is rolled out and the Y DNA Family Finder haplogroups are completed, Family Finder customers, where possible, will also receive at least a basic-level mitochondrial haplogroup. Not all upload files from other vendors include mtDNA SNPs in their autosomal files. The mitochondrial Family Finder haplogroup feature isn’t expected until sometime in 2025, after the new tree and MitoDiscover are complete.

The Future

What’s coming later in 2024, or is ongoing?

Privacy Laws

Most people aren’t aware of the new privacy laws in various states, each of which has to be evaluated and complied with.

The effects of these changes will be felt in various areas as they are implemented.

New Kits Opted Out of IGG

Since late August, all new FTDNA kits are automatically opted OUT of Investigative Genetic Genealogy (IGG) by default.

Regular matching consent and IGG matching consent have been separated during onboarding.

Biobanking Separate Consent

Another consent change is to have your sample biobanked. FamilyTreeDNA has always maintained your sample for “roughly 25 years.” You could always ask to have your sample destroyed, but going forward, you will be asked initially if you want your sample to be retained (biobanked.) It’s still free.

Remember, if someone declines the biobanking option, their DNA will be disposed of after testing. They can’t order upgrades without submitting a new sample. Neither can their family after they’re gone. I ordered my mother’s Family Finder test many years after she had gone on to meet our ancestors – and I’m incredibly grateful every single day.

MyHeritage Tree Integration

An exciting change coming next year is tree integration with MyHeritage.

And no, before any rumors get started, FAMILYTREEDNA IS NOT MERGING WITH MYHERITAGE. It’s a beneficial marriage of convenience for both parties.

In essence, one of the primary focuses of MyHeritage is trees, and they do that very well. FamilyTreeDNA is focused on DNA testing and their existing trees have had issues for years. MyHeritage trees are excellent, support pedigree collapse, provide search capabilities that are NOT case sensitive, SmartMatching, and much more.

If you don’t have a MyHeritage account, creating one is free, and you will be able to either port your existing FamilyTreeDNA tree, or begin one there. If you’re already a MyHeritage member, FamilyTreeDNA and MyHeritage are planning together for a smooth integration for you. More detailed information will be forthcoming as the integration progressed and is released to customers.

You’ll be able to connect multiple kits to your tree at MyHeritage, just like you can at FamilyTreeDNA today, which enables family matching, aka bucketing.

You can also have an unlimited number of different trees at MyHeritage on the same account. You’re not limited to one.

After you link your initial FamilyTreeDNA kit to the proper person in your MyHeritage tree, you’ll be able to relink any currently linked kits.

MyHeritage will NOT receive any DNA information or match information from FamilyTreeDNA, and yes, you’ll be able to use the same tree independently at MyHeritage for their DNA matching.

You’ll still be able to view your matches’ trees, except it will actually be the MyHeritage tree that will be opened at FamilyTreeDNA in a new tab.

To the best of my knowledge, this is a win-win-win, and customers of both companies aren’t losing anything.

One concern is that some FamilyTreeDNA testers have passed away and cannot transition their tree, so a view-only copy of their tree will remain at FamilyTreeDNA so that their matches can still see their tree.

Big Y Infrastructure

Katy mentioned that internal discussions are taking place to see what changes could be made to improve things like matching and test processing times.

No changes are planned for SNP or STR coverage, but discussions are taking place about a potential update to the Telomere to Telomere (T2T) reference. No promises about if or when this might occur. The last part of the human genome to be fully sequenced, the T2T reference model includes the notoriously messy and unreliable region of the Y chromosome with many repeats, duplications, gaps, and deletions. Some data from this region is probably salvageable but has previously been omitted due to the inherent problems.

I’m not sure this shouldn’t be in the next section, the Wishlist.

Wishlist

There are lots of good things on the Wishlist – all of which I’d love.

I’d have difficulty prioritizing, but I’d really appreciate some Family Finder features in addition to the items already discussed. I’d also like to see some GAP (administrator) tool updates.

Which items do you want to see most?

Katy said that FamilyTreeDNA is NOT planning to offer a Whole Genome Sequencing (WGS) test anytime soon. So, if you’re holding your breath, please don’t. Based on what Katy did say, WGS is very clearly not a consideration in 2024 and I don’t expect to see it in 2025 either unless something changes drastically in terms of technology AND pricing.

While WGS prices have come down, those consumer tests are NOT scanned at the depth and quality required for advanced tests like the Big Y or even Family Finder. Normally consumer-grade WGS tests are scanned between 2 and 10 times, where the FamilyTreeDNA lab scans up to 30 times in order to obtain a quality read. 30X scans are in the same category as medical or clinical grade whole genome scans. Significantly higher quality scans mean significantly higher prices, too, so WGS isn’t ready for genealogy prime time yet.

Additionally, commercially available WGS tests are returned to the customer “as is,” and you’re left to extract the relevant SNPs and arrange them into files, or find someone else to do that. Not to mention, in order to preserve the integrity of their database, FamilyTreeDNA does not accept Y or mitochondrial DNA uploads.

Recently, I saw two WGS files with a 20-25% no-call rate for the autosomal SNPs required for the Family Finder test. Needless to say, that’s completely unacceptable. Some tools attempt to “fix” that mess by filling in the blanks in the format of either a 23andMe or Ancestry file so you can upload to vendors, but that means you’re receiving VERY unreliable matches.

The reason none of the major four vendors offer WGS testing for genealogists is because it’s not financially feasible nor technologically beneficial. The raw data file alone won’t fit on most home computers. WGS is just not soup yet, and it won’t be for the general consuming public, including relevant tools, for at least a few years.

I’ve had my whole genome sequenced, and trust me, I wish it were feasible now, but it just isn’t.

Suggestions Welcomed

Katy said that if you have suggestions for items NOT on the wishlist today to contact her through support.

I would add that if you wish to emphasize any specific feature or need above others, please send that feedback, politely, to support as well.

Katy ended by thanking the various teams and individuals whose joint efforts together produce the products we use and enjoy today.

Lab Update

Normally, DNA testing companies don’t provide lab updates, but this conference is focused on group project administrators, who are often the most dedicated to DNA testing.

A lab update has become a tradition over the years.

Linda Jones, Lab Manager, provided a lab update.

You may or may not know that the FamilyTreeDNA lab shifted gears and stepped up to handle Covid testing.

Supply-chain shortages interfered, but the lab ran 24×7 between 2020 and 2022.

Today, the lab continues to make improvements to processes with the goal of delivering the highest quality results in a timely manner.

On Monday, after the conference, attendees could sign up for a lab tour. You might say we are a rather geeky bunch and really enjoy the science behind the scenes.

Q&A and Thank You

At the end of the conference, the FamilyTreeDNA management team answered questions from attendees.

Left to right, Daniel Au, CTO; Linda Jones, Lab Manager; Katy Rowe-Schurwanz, Product Manager; Clayton Conder, VP Marketing; Goran Runfeldt, Head of R&D; and Andrew Gefre, Development Manager. Not pictured, Jeremy Balkin, Support Manager; Kelly Jenkins, VP of Operations; and Janine Cloud, Group Projects Manager. Janine is also responsible for conferences and events, without whom there would have been no 2023 FamilyTreeDNA conference. Janine, I can’t thank you enough!

A huge thanks to all of these people and many others, including the presenters, CSRs, IT, and other FamilyTreeDNA team members for their support during the conference, enabling us to enjoy the conference and replenish the well of knowledge.

Haplogroups: DNA SNPs Are Breadcrumbs – Follow Their Path

Posted on August 10, 2023 by Roberta Estes

Recently a reader asked some great questions.

If Y-DNA is unchanged, then why isn’t the Y-DNA of every man the same today? And if it’s not the same, then how do we know that all men descend from Y-Adam? Are the scientists just guessing?

The scientists aren’t guessing, and the recent scientific innovations behind how this works is pretty amazing, so let’s unravel these questions one at a time.

The first thing we need to understand is how Y-DNA is inherited differently from autosomal DNA, and how it mutates.

First, a reminder that:

Y-DNA tests the Y chromosome passed from father to son in every generation, unmixed with any DNA of the mother. This article focuses on Y-DNA.
Mitochondrial DNA tests the mitochondria passed from mothers to all of their children, but is only passed on by the females, unmixed with the DNA of the father. This article also pertains to mitochondrial SNPS, but we will cover that more specifically later in another article.
Autosomal DNA is passed from both parents to their children. Each child inherits half of each parent’s autosomal DNA.

Let’s look at how this works.

Autosomal vs Y-DNA Inheritance

Click on image to enlarge

Autosomal DNA, shown here with the green (male) and pink (female) images, divides in each generation as it’s passed from the parent to their child. Each child inherits half of each parent’s autosomal DNA, meaning chromosomes 1-22. For this discussion, each descendant shown above is a male and has a Y chromosome.

This means that in the first generation, which would be the great-grandfather, about 700,000 locations of his green autosomal DNA are tested for genealogy purposes.

His female partner (pink) also has about 700,000 locations. During recombination, they each contribute about 350,000 SNPs (Single Nucleotide Polymorphisms) of autosomal DNA to their child. Their offspring then has a total of 700,000 SNPs, 350,000 green and 350,000 pink contributed by each parent.

This process is repeated for each child, whether male or female (with the exception of the X chromosome, which is beyond the scope of this article), but each child does not receive exactly the same half of their parents’ autosomal DNA. Recombination is random.

In the four generations shown above, the green autosomal DNA of generation one, the great-grandfather, has been divided and recombined three times. The original 700,000 locations of great-grandfather’s green DNA has now been whittled down to about 87,500 locations of his green DNA.

Y-DNA in the Same Generation

Looking now at the blue Y-DNA at left, the Y-DNA remains the same in each generation with the exception of one mutation approximately every two or three generations.

As you can see in the chart, in the exact same number of generations, the Y-DNA of each male, which he inherited from his father:

Never recombines with any DNA from the mother
Never divides and gets smaller in subsequent generations
Remains essentially unchanged in each generation

The key word here is “essentially.”

Y-DNA

The Y chromosome consists of about 59 million locations or SNPs of DNA. STR tests, Short Tandem Repeats, which are essentially insertions and deletions, test limited numbers of carefully curated markers selected for the fact that they mutate in a genealogically relevant timeframe. These markers are combined in panels of either 67 or 111 marker tests available for purchase at FamilyTreeDNA today, or historically 12, 25, 37, 67, and 111 marker panels. The STR test was the original Y-DNA test for genealogy and is still used as an introductory test or to see if a male matches a specific line, or not.

From the STR tests, in addition to matching, FamilyTreeDNA can reliably predict a relatively high-level haplogroup, or genetic clan, based on the frequency of the combinations of those marker values in specific STR locations.

SNPs are much more reliable than STRs, which tend to be comparatively unstable, mutating at an unreliable rate, and back mutating, which can be very disconcerting for genealogy. We need reliable consistency to be able to assign a male tester to a specific lineage with confidence. We can, however, find genealogically relevant matches that may be quite important, so I never disregard STR tests or testers. STR tests aren’t relevant for deeper history, nor can they reliably discern a specific lineage within a surname. SNP tests can and do.

The Big Y-700 SNP test gives us that and more, along with the earlier Big Y-500 test which scanned about 30 million locations. The Big Y-700 is a significant improvement; men can upgrade from the Big Y-500 or STR tests.

The Big Y-700 test scans about 50 million Y-DNA locations, known as the gold standard region, for all mutations. It reports 700 or more STR markers for matching, but more importantly, it scans for all SNP mutations in those 50 million locations.

All mutations are confirmed by at least five positive repeat scans and are then assigned a haplogroup name if found in two or more men.

Y-DNA Testing

If Y-DNA remained exactly the same, then the Y-DNA of men today would be entirely indistinguishable from each other – essentially all matching humankind’s first common ancestor. With no changes, Y-DNA would not be useful for genealogy. We need inherited mutations to be able to compare men and determine their level of relatedness to each other.

Fortunately, Y-DNA SNPs do mutate. Y-DNA is never divided or combined, so it stays essentially the same except for occasional mutations which are inherited by the following generations.

Using SNP markers scanned in the Big Y test, one new mutation happens on the average of every two or three generations. Of course, that means that sometimes there are no mutations for a few generations, and sometimes there are two mutations between father and son.

What this does, though, very effectively, is provide a trail of SNP mutations – breadcrumbs essentially – that we can use for matching, AND for tracking our mutations, which equate to ancestors, back in time.

Estes Male Breadcrumb Trail

I’ve tested several Estes men of known lineage, so I’m going to use this line as an example of how mutations act as breadcrumbs, allowing us to track our ancestors back in time and across the globe.

Multiple cousins in my Estes line have taken the Big Y-700 test.

My closest male cousin matches two other men on a unique mutation. That SNP has been named haplogroup R-ZS3700.

We know, based on our genealogy, that this mutation occurred in Virginia and is found in the sons of Moses Estes born in 1711.

How do we know that?

We know that because three of Moses’s descendants have tested and all three of those men have the same mutation, R-ZS3700, and none of the sons of Moses’s brothers have that mutation.

I’ve created a chart to illustrate the Estes pedigree chart, and the haplogroups assigned to those men. So, it’s a DNA pedigree chart too. This is exactly what the Big-Y DNA test does for us.

In the red-bordered block of testers, you can see the three men that all have R-ZS3700 (in red), and all are sons of Moses born in 1711. I have not typed the names of all the men in each generation because, for purposes of this illustration, names aren’t important. However, the concept and the fact that we have been able to connect them genealogically, either before or because of Y-DNA testing, is crucial.

Directly above Moses born in 1711, you can see his father Abraham born in 1647, along with Moses’ brothers at right and left; John, Richard, Sylvester, and Elisha whose descendants have taken the Big Y-700 test. Moses’s brothers’ descendants all have haplogroup R-BY490 (in blue), but NOT R-ZS3700. That tells us that the mutation responsible for R-ZS3700 happened between Abraham born in 1647, and Moses born in 1711. Otherwise, Moses’s brothers would have the mutation if his father had the mutation.

Moses’s descendants also have R-BY490, but it’s NOT the last SNP or haplogroup in their lineage. For Moses’s descendants, R-ZS3700 occurred after R-BY490.

You can see haplogroup R-BY490 boxed in blue.

We know that Moses and his father, Abraham, both have haplogroup R-BY490 because all of Abraham’s sons have this haplogroup. Additionally, we know that Abraham’s father, Silvester also had haplogroup R-BY490.

How do we know that?

Abraham’s brother, Richard’s descendant, tested and he has haplogroup R-BY490.

However, Silvester’s father, Robert born in 1555 did NOT have R-BY490, so it formed between him and his son, Silvester.

How do we know that?

Robert’s other son, Robert born in 1603 has a descendant who tested and has haplogroup R-BY482, but does NOT have R-BY490 or R-ZS3700.

All of the other Eates testers also have R-BY482, blocked in green, in addition to R-BY490, so we know that the mutation of R-BY490 developed between Robert born in 1555 and his son, Silvester born in 1600, because his other son’s descendant does not have it.

Looking at only the descent of the haplogroups, in order, we have

R-BY482 (green) found in Robert born in 1555 and all of his descendants.
R-BY490 (blue) found in Silvester born in 1600 and all of his descendants, but not his brother
R-ZS3700 (red) found in Moses born in 1711 and all of his descendants, but not his brothers

If we had Estes men who descend from the two additional documented generations upstream of Robert born in 1555, we might discover when R-BY482 occurred, but to date, we don’t have any additional testers from those lines.

Now that we understand the genesis of these three haplogroups in the Estes lineage, what else can we discover through our haplogroup breadcrumbs?

The Discover Reports

By entering the haplogroup in the Discover tool, either on the public page, here, or clicking on Discover on your personal page at FamilyTreeDNA if you’ve taken the Big-Y test, you will see several reports for your haplogroup.

I strongly suggest reviewing each category, because they cumulatively act as chapters to the book of your haplogroup story, but we’re going to skip directly to the breadcrumbs, which is called the Ancestral Path.

The Ancestral Path begins with your haplogroup in Line 1 then lists the first upstream or parent haplogroup in Line 2. In this case, the haplogroup I entered is R-ZS3700.

You can see the estimated age of the haplogroup, meaning when it formed, at about 1700 CE. Moses Estes who was born in 1711 is the first Estes man to carry haplogroup R-ZS3700, so that’s extremely close.

Line 2, R-BY490 occurred or was born about 1650, and we know that it actually occurred between Robert and Silvester born in 1600, so that’s close too.

Scanning down to Line 3, R-BY482 is estimated to have occurred about 1500 CE, and we know for sure it had occurred by 1555 when Robert was born.

We see the parent haplogroup of R-BY487 on Line 4, dating from about 750 CE. Of course, if more men test, it’s possible that more haplogroups will emerge between BY482 and BY487, forming a new branch. Given the time involved, those men wouldn’t be expected to carry the Estes surname, as surnames hadn’t yet been adopted in that timeframe.

Moving down to Line 9, we see R-ZP18 from 2250 BCE, or about 4250 years ago. Looking at the right column, there’s one ancient sample with that haplogroup. The location of ancient samples anchors haplogroups definitively in a particular location at a specific time.

Haplogroup by haplogroup, step by step, we can follow the breadcrumbs back in time to Y-Adam, the first homo sapiens male known to have descendants today, meaning he’s the MRCA, or most recent common ancestor for all men.

Neanderthals and Denisovans follow, but their Y-DNA is only available through ancient samples. They have no known direct male survivors, but someday, maybe someone will test and their Y-DNA will be found to descend from Neanderthals or Denisovans.

Now that we know when those haplogroups occurred, how did our ancestors get from Africa 232,000 years ago to Kent, England, in the 1400s? What path did they take?

The new Globetrekker tool answers that question.

The Breadcrumb Trail

In Globetrekker, each haplogroup’s location is placed by a combination of testers’ results, their identified earliest known ancestor (EKA) country and location, combined with ancient samples, climatic factors like glaciers and sea levels, and geographic features. You can read about Globetrekker here and here.

To view the Globetrekker tool, you must sign it to an account that has taken the Big Y test. It’s a tool exclusively provided for Big-Y testers.

You can click at the bottom of your Globetrekker map to play the animated video.

Beginning in Africa, our ancestors began their journey with Y-Adam, then migrated through the Near East, South Asia, East Asia, then west through central Asia into Europe. The Estes ancestors crossed the English Channel and migrated around what is now England before settling in Deal, on the east coast.

Clicking on any haplogroup provides a description of that haplogroup and how it was placed in that location.

Enabling the option for ancient DNA shows those locations as well, near the haplogroups they represent when the animation is playing.

Clicking on the shovel icon explains about that particular ancient DNA sample, what is known, and how it relates to the haplogroup it’s connected to by a dotted line on the map.

Pretty cool, huh!!

End to End

As you can see from this example, Big Y results are an end-to-end tool.

We can use the Big Y-700 haplogroups very successfully for recent genealogy – assigning testers to specific lines in a genealogy timeframe. Some haplogroups are so specific that, without additional information, we can place a man in his exact generation, or within a generation or two.

Not shown in my Estes pedigree chart is an adoptee with a different surname, of course. We know that he descends from Moses’s line because he carries haplogroup R-ZS3700, but we are still working on the more recent generations using autosomal DNA to connect him accurately. If more of Moses’s descendants tested, we could probably place him very specifically. Without the Big Y-700 test, he wouldn’t know his biological surname or that he descends from Moses. That’s a HUGE breakthrough for him.

There’s more about the Estes line to learn, however.

If our Estes cousins tested their brothers, uncles or other Estes males in their line, they would likely receive a more refined haplogroup that’s relevant only to that line.

Using Big-Y test results, we can place men within a couple of generations and identify a common ancestor, even when all men within a haplogroup don’t know their genealogical lineage. Using those same test results, we can follow the breadcrumbs all 50 steps back in time more than 230,000 years to Y-Adam.

End to end, the Big-Y test coupled with breadcrumbs in Discover, Globetrekker, and other amazing tools is absolutely the most informative and powerful test available to male testers for their paternal line genealogy.

These amazing innovations tracking more than 50,000 haplogroups across the globe answer the original questions about how we know.

The more people who take or upgrade to the Big Y-700 test, the more haplogroup branches will be added, and the more refined the breadcrumbs, ages, and maps will become. In other words, there’s still more to learn.

Test if you haven’t, and check back often for new matches and breadcrumbs, aka updates.

X Chromosome Master Class

Posted on March 28, 2023 by Roberta Estes

The X chromosome can be especially useful to genetic genealogists because it has a unique inheritance path. Thanks to that characteristic, some of the work of identifying your common ancestor is done just by simply HAVING an X match.

Unfortunately, X-DNA and X matching is both underutilized and somewhat misunderstood – in part because not all vendors utilize the X chromosome for matching.

The X chromosome has the capability of reaching further back in time and breaking down brick walls that might fall no other way.

Hopefully, you will read this article, follow along with your own DNA results and make important discoveries.

Let’s get started!

Who Uses the X Chromosome?

The X chromosome is autosomal in nature, meaning it recombines under some circumstances, but you only inherit your X chromosome from certain ancestors.

It’s important to understand why, and how to utilize the X chromosome for matching. In this article, I’ve presented this information in a variety of ways, including case studies, because people learn differently.

Of the four major testing vendors, only two provide X-DNA match results.

FamilyTreeDNA – provides X chromosome results and advanced matching capabilities including filtered X matching
23andMe – provides X chromosome results, but not filtered X matching without downloading your results in spreadsheet format
Ancestry and MyHeritage do not provide X-DNA results but do include the X in your raw DNA file so you can upload to vendors who do provide X matching
GEDmatch – not a DNA testing vendor but a third-party matching database that provides X matching in addition to other tools

It’s worth noting at this point that X-DNA and mitochondrial DNA is not the same thing. I wrote about that, here. The source of this confusion is that the X chromosome and mitochondrial DNA are both associated in some way with descent from females – but they are very different and so is their inheritance path.

So, what is X-DNA and how does it work?

What is X-DNA?

Everyone inherits two copies of each of chromosomes 1-22, one copy of each chromosome from each of your parents.

That’s why DNA matching works and each match can be identified as “maternal” or “paternal,” depending on how your match is related to you. Each valid match (excluding identical by chance matches) will be related either maternally, or paternally, or sometimes, both.

Your 23^rd chromosome is your sex determination chromosome and is inherited differently. Chromosome 23 is comprised of X and Y DNA.

Everyone inherits one copy of chromosome 23 from each parent.

Males inherit a Y chromosome from their father, which is what makes males male. They do not inherit an X chromosome from their father.
Males always inherit an X chromosome from their mother.
Females inherit an X chromosome from both parents, which is what makes them female. Females have two X chromosomes, and no Y chromosome.

Chromosome 23	Father Contributes	Mother Contributes
Male Child	Y chromosome	X chromosome
Female Child	X chromosome	X chromosome

X-DNA and mitochondrial DNA are often confused, but they are not the same thing. In fact, they are completely different.

Mitochondrial DNA, in BOTH males and females is always inherited from only the mother and only descends from the direct matrilineal line, so only the mother’s mother’s mother’s direct line. X DNA can be inherited from a number of ancestors based on a specific inheritance path.

Everyone has both X-DNA AND mitochondrial DNA.

Because males don’t inherit an X chromosome from their father, X chromosome matching has a unique and specific pattern of descent which allows testers who match to immediately eliminate some potential common ancestors.

Males only inherit an X chromosome from their mother, which means they can only have legitimate X matches on their mother’s side of their tree.
Females, on the other hand, inherit an X chromosome from both their mother and father. Their father only has one X chromosome to contribute, so his daughter receives her paternal grandmother’s X chromosome intact.
Both males and females inherit their mother’s X chromosome just like any of the other 22 autosomes. I wrote about chromosomes, here.

However, the unique X chromosome inheritance path provides us with a fourth very useful type of DNA for genealogy, in addition to Y-DNA, mitochondrial and autosomal DNA.

For the vendors who provide X-matching, it’s included with your autosomal test and does not need to be purchased separately.

The Unique X Chromosome

The X chromosome, even though it is autosomal in nature, meaning it does recombine and divide in certain circumstances, is really its own distinct tool that is not equivalent to autosomal matching in the way we’re accustomed. We just need to learn about the message it’s delivering and how to interpret X matches.

FamilyTreeDNA is one of two vendors who utilizes X chromosome matching, along with 23andMe, which is another good reason to encourage your matches at other vendors to upload their DNA file to FamilyTreeDNA for free matching.

The four major vendors do include X-DNA results in their raw DNA download file, even if they don’t provide X-matching themselves. This means you can upload the results to either FamilyTreeDNA or GEDmatch where you can obtain X matches. I provided step-by-step download/upload instructions for each vendor here.

Let’s look how X matching is both different, and beneficial.

My X Chromosome Family Tree

We are going to build a simple case study. A case study truly is worth 1000 descriptions.

This fan chart of my family tree colorizes the X chromosome inheritance path. In this chart, males are colored blue and females pink, but the salient point is that I can inherit some portion of (or all of) a copy of my X chromosome from the colorized ancestors, and only those ancestors.

Because males don’t inherit an X chromosome from their father, they CANNOT inherit any portion of an X chromosome from their father’s ancestors.

Looking at my father’s half of the chart, at left, you see that I inherited an X chromosome from both of my parents, but my father only inherited an X chromosome from his mother, Ollie Bolton. His father’s portion of the tree is uncolored, so no X chromosome could have descended from his paternal ancestors to him. Therefore he could not pass any X chromosome segments to me from his paternal side – because he doesn’t have X DNA from his father.

Hence, I didn’t inherit an X chromosome from any of the people whose positions in the chart are uncolored, meaning I can only inherit an X chromosome from the pink or blue people.

Essentially any generational male to male, meaning father/son relationship is an X-DNA blocker.

I know positively that I inherited my paternal grandmother, Ollie Bolton’s entire X chromosome, because hers is the only X chromosome my father, in the fan chart above, had to give me. His entire paternal side of the fan chart is uncolored.

Men only ever inherit their X chromosome from their mother. The only exception to this is if a male has the rare genetic condition of Klinefelter Syndrome, also known as XXY. If you are an adult male, it’s likely that you’ll already know if you have Klinefelters, so that’s probably the last possibility you should consider if you appear to have paternal X matches, not the first.

Sometimes, men appear to have X matches on their father’s side, but (barring Klinefelter’s) this is impossible. Those matches must either be identical by chance, or somehow related in an unknown way on their mother’s side.

Everyone inherits an X chromosome from their mother that is some combination of the X from her father and mother. It’s possible to inherit all of your maternal grandmother or maternal grandfather’s X chromosome, meaning they did not recombine during meiosis.

Using DNA Painter as an X Tool

I use DNAPainter to track my matches and correlate segments with ancestors.

I paint my DNA segments for all my chromosomes at DNAPainter which provides me with a central tracking mechanism that is visual in nature and allows me to combine matches from multiple vendors who provide segment information. I provide step-by-step instructions for using DNAPainter, here.

This is my maternal X chromosome with my matches painted. I’ve omitted my matches’ names for privacy.

On the left side of the shaded grey column, those matches are from my maternal grandmother’s ancestors. On the right side, those matches are from my maternal grandfather’s ancestors.

The person in the grey column descends from unknown ancestors. In other words, I can tell that they descend from my maternal line, but I can’t (yet) determine through which of my two maternal grandparents.

There’s also an area to the right of the grey column where there are no matches painted, so I don’t know yet whether I inherited this portion of my X chromosome from my maternal grandmother or maternal grandfather.

The small darker pink columnar band is simply marking the centromere of the chromosome and does not concern us for this discussion.

Click on any image to enlarge

In this summary view of my paternal X chromosome, above, it appears that I may well have inherited my entire X chromosome from my paternal great-grandmother. We know, based on our inheritance rules that I clearly received my paternal grandmother’s X chromosome, because that’s all my father had to give me.

However, by painting my matches based on their ancestors, and selecting the summary view, you can see that most of my paternal X chromosome can be accounted for, with the exception of rather small regions with the red arrows.

It’s not terribly unusual for either a male or female to inherit their entire maternal X chromosome from one grandparent, or in this case, great-grandparent.

Of course, a male doesn’t inherit an X chromosome from their father, but a female can inherit her paternal X chromosome from either or both paternal grandparents.

Does Size Matter?

Generally speaking, an X match needs to be larger than a match on the other chromosomes to be considered genealogically equivalent in the same timeframe as other autosomal matches. This is due to:

The unique inheritance pattern, meaning fewer recombination events occurred.
The fact that X-DNA is NOT inherited from several lines.
The X chromosome has lower SNP density, meaning it contains fewer SNPs, so there are fewer possible locations to match when compared to the other chromosomes.

I know this equivalency requirement sounds negative, but it’s actually not. It means 7 cM (centimorgans) of DNA on the X chromosome will reach back further in time, so you may carry the DNA of an ancestor on the X chromosome that you no longer carry on other chromosomes. It may also mean that older segments remain larger. It’s actually a golden opportunity.

It sounds much more positive to say that a 16 cM X match for a female, or a 13 cM X match for a male is about the same as a 7 cM match for any other autosomal match in the same generation.

Of course, if the 7 cM match gets divided in the following generation, it has slipped below the matching threshold. If a 16 or 13 cM X match gets divided, it’s still a match. Plus, in some generations, if passed from father to daughter, it’s not divided or recombined. So a 7 cM X match may well be descended from ancestors further back in time.

X Chromosome Differences are Important!

Working with our great-great grandparent’s generation, we have 16 direct ancestors as illustrated in the earlier fan chart.

Given that females inherit from 8 X-chromosome ancestors in total, they are going to inherit an average of 45.25 cM of X-DNA from each of those ancestors. Females have two X chromosomes for a total length of 362 cM of X-DNA from both parents.

A male only has one X chromosome, 181 cM in length, so he will receive an average of 36.2 cM from each of 5 ancestors, and it’s all from his mother’s side.

In this chart, I’ve shown the total number of cMs for all of the autosomes, meaning chromosomes 1-22 and, separately, the X for males and females.

The average total cM for chromosomes 1-22 individually is 304 cM. (Yes, each chromosome is a different length, but that doesn’t matter for averages.)
That 304 cM can be inherited from any of 16 ancestors (in your great-grandparent’s generation)
The total number of cM on the X chromosomes for both parents for females totals 362
The total cM of X-DNA for males is 181 cM
The calculated average cM inherited for the X chromosome in the same generation is significantly different, shown in the bottom row.

The actual average for males and females for any ancestor on any random non-X chromosome (in the gg-grandparent generation) is still 19 cM. Due to the inheritance pattern of the X chromosome, the female X-chromosome average inheritance is 45.25 cM and the male average is 36.2 cM, significantly higher than the average of 19 cM that genetic genealogists have come to expect at this relationship distance on the other chromosomes, combined.

How Do I Interpret an X Match?

It’s important to remember when looking at X matching that you’re only looking at the amount of DNA from one chromosome. When you’re looking at any other matching amount, you’re looking at a total match across all chromosomes, as reported by that vendor. Vendors report total matching DNA differently.

The total amount of matching autosomal DNA does not include the X chromosome cMs at FamilyTreeDNA. X-DNA matching cMs are reported separately.
The total amount of matching autosomal DNA does include the X chromosome cMs in the total cM match at 23andMe
X-DNA is not used for matching or included in the match amount at either MyHeritage or Ancestry, but is included in the raw DNA data download files for all four vendors.
The total match amount shows the total for 22 (or 23) chromosomes, NOT just the X chromosome(s). That’s not apples to apples.

Therefore, an X match of 45 cM for a female or 36 for a male is NOT (necessarily) equivalent to a 19 cM non-X match. That 19 cM is the total for 22 chromosomes, while the X match amount is just for one chromosome.

You might consider a 20 cM match on the regular autosomes significant, but a 20 cM X-only match *could* be only roughly equivalent to a 10ish cM match on chromosomes 1-22 in the same generation. That’s the dog-leg inheritance pattern at work.

This is why FamilyTreeDNA does not report an X-only match if there is no other autosomal match. A 19 cM X match is not equivalent to a 19cM match on chromosomes 1-22. Not to mention, calculating relationships based on cM ranges becomes more difficult when the X is included.

However, the flip side is that because of the inheritance pattern of the X chromosome, that 19 cM match, if valid and not IBC, may well reach significantly further back in time than a regular autosomal matches. This can be particularly important for people seeking either Native or enslaved African ancestors for whom traditional records are elusive if they exist at all.

Critical Take-Away Messages

Here are the critical take-away messages:

Because there are fewer ancestral lineages contributing to the tester’s X chromosome, the amount of X chromosomal DNA that a tester inherits from the ancestors who contribute to their X chromosome is increased substantially.
The DNA of the contributing ancestors is more likely to be inherited, because there are fewer other possible contributing ancestors, meaning fewer recombination events or DNA divisions/recombinations.
X-DNA is also more likely to be inherited because when passed from mother to son, it’s passed intact and not admixed with the DNA of the father.
X matches cannot be compared equally to either percentages or cM amounts on any of the other chromosomes, or autosomal DNA in total, because X matching only reports the amount on one single chromosome, while your total cM match amount reports the amount of DNA that matches from all chromosomes (which includes the X at 23andMe).
If you have X matches at 23andMe and/or FamilyTreeDNA, you can expect your total matching to be higher at 23andMe because they include the X matching cM in the total amount of shared DNA. FamilyTreeDNA provides the amount of X matching DNA separately, but not included in the total. MyHeritage and Ancestry do not include X matching DNA.

For clarity, at FamilyTreeDNA, you can see my shared DNA match with my mother. Of course, I match her on the total length of all my chromosomes, which is 3563 cM, the total Shared DNA for chromosomes 1-22. This includes all chromosomes except for the X chromosome which is reported separately at 181 cM. The longest contiguous block of shared DNA is 284 cM, the entire length of chromosome 1, the longest chromosome.

Because I’m a female, I match both parents on the full length of all 23 chromosomes, including 181 cM on both X chromosomes, respectively. Males will only match their mother on their X chromosome, meaning their total autosomal DNA match to their father, because the X is excluded, is 181 cM less than to their mother.

This difference in the amount of shared DNA with each parent, plus the differences in how DNA totals are reported by various vendors is also challenging for tools like DNAPainter’s Shared cM Tool which is based on the crowd sourced Shared cM Project that averages shared DNA numbers for known relationships at various vendors and translates those numbers into possible relationships for unknown matches.

Not all vendors report their total amount of shared DNA the same way. This is true for both X-DNA and half identical (HIR) versus fully identical (FIR) segments at 23andMe. This isn’t to say either approach is right or wrong, just to alert you to the differences.

Said Another Way

Let’s look at this another way.

If the average on any individual chromosome is 19 cMs for a relationship that’s 5 generations back in time. The average X-DNA for the same distance relationship is substantially more, which means that:

The X-DNA probably reaches further back in time than an equivalent relationship on any other autosome.
The X-DNA will have (probably) divided fewer times, and more DNA will descend from individual ancestors.
The inheritance path, meaning potential ancestors who contributed the X chromosomal DNA, is reduced significantly.

It’s challenging to draw equivalences when comparing X-DNA matching to the other chromosomes due to several variables that make interpretation difficult.

Based on the X-match size in comparison to the expected 19 cM single chromosome match at this genealogical distance, what is the comparable X-DNA segment size to the minimum 7 cM size generally accepted as valid on other chromosomes? What would be equal to a 7 cM segment on any other single random autosomal match, even though we know the inheritance probabilities are different and this isn’t apples to apples? Let’s pretend that it is.

This calculation presumes at the great-great-grandparent level that the 19 cM is in one single segment on a single chromosome. Now let’s divide 19 cM by 7 cM, which is 2.7, then divide the X amounts by the same number for the 7 cM equivalent of 16.75 cM for a female and 13.4 cM for a male.

When people say that you need a “larger X match to be equivalent to a regular autosomal match,” this is the phenomenon being referenced. Clearly a 7 cM X match is less relevant, meaning not equivalent, in the same generation as a 7 cM regular autosomal match.

Still, X matching compared to match amounts shown on the other chromosomes is never exact;u apples to apples because:

You’re comparing one X chromosome to the combined DNA amounts of many chromosomes.
The limited recombination path.
DNA from the other autosomes is less likely to be inherited from a specific ancestor.
The X chromosome has a lower SNP density than the other chromosomes, meaning fewer SNPs per cM.
The X-DNA may well reach further back in time because it has been divided less frequently.

Bottom Line

The X chromosome is different and holds clues that the other autosomes can’t provide.

Don’t dismiss X matches even if you can’t identify a common ancestor. Given the inheritance path, and the reduced number of divisions, your X-DNA may descend from an ancestor further back in time. I certainly would NOT dismiss X matches with smaller cMs than the 13 and 16 shown above, even though they are considered “equivalent” in the same generation.

X chromosome matching can’t really be equated to matching on the other chromosomes. They are two distinct tools, so they can’t be interpreted identically.

Different vendors treat the X chromosome differently, making comparison challenging.

23andMe includes not only the X chromosome in their cM total, but doubles the Fully Identical Regions (FIR) when people, such as full siblings, share the same DNA from both parents. I wrote about that here.
Ancestry does not include the X in their cM match calculations.
Neither does MyHeritage.
FamilyTreeDNA shows an X match only when it’s accompanied by a match on another chromosome.

The Shared cM Project provides an average of all of the data input by crowdsourcing from all vendors, by relationship, which means that the cM values for some relationships are elevated when compared to the same relationship or even same match were it to be reported from a different vendor.

The Best Part!

The X chromosome inheritance pattern means that you’re much more likely to carry some amount of a contributing ancestor’s X-DNA than on any other chromosome.

X-DNA may well be “older” because it’s not nearly as likely to be divided, given that there are fewer opportunities for recombination.
When you’re tracking your X-DNA back in your tree, whenever you hit a male, you get an automatic “bump” back a generation to his mother. It’s like the free bingo X-DNA square!
You can immediately eliminate many ancestors as your most recent common ancestor (MRCA) with an X-DNA match.
Because X-DNA reaches further back in time, sometimes you match people who descend from common ancestors further back in time as well.

If you match someone on multiple segments, if one of those matching segments is X-DNA, that segment is more likely to descend from a different ancestor than the segments on chromosomes 1-22. I’ve found many instances where an X match descends from a different ancestor than matching DNA segments on the autosomes. Always evaluate X matches carefully.

Sometimes X-DNA is exactly what you need to solve a mystery.

Ok, now let’s step through how to use X-DNA in a real-life example.

Using X DNA to Solve a Mystery

Let’s say that I have a 30 cM X match with a male.

I know immediately that our most recent common ancestor (MRCA) is on HIS mother’s side.
I know, based on my fan chart, which ancestral lines are eliminated in my tree. I’ve immediately narrowed the ancestors from 16 to 5 on his side and 16 to 8 on my side.
Two matching males is even easier, because you know immediately that the common ancestor must be on both of their mother’s sides, with only 5 candidate lines each at the great-great-grandparent generation.

Female to female matches are slightly more complex, but there are still several immediately eliminated lines each. That means you’ve already eliminated roughly half of the possible relationships by matching another female on their X chromosome.

In this match with a female second cousin, I was able to identify who she was via our common ancestor based on the X chromosome path. In this chart, I’m showing the relevant halves of her chart at left (paternal), and mine (maternal), side by side.

I added blockers on her chart and mine too.

As it turns out, we both inherited most of our X chromosome from our great-grandparents, marked above with the black stars.

Several lines are blocked, and my grandfather’s X chromosome is not a possibility because the common ancestor is my maternal grandmother’s parents. My grandfather is not one of her ancestors.

Having identified this match as my closest relative (other than my mother) to descend on my mother’s maternal side, I was able to map that portion of my X chromosome to my great-grandparents Nora Kirsch and Curtis Benjamin Lore.

My X Chromosome at DNA Painter

Here’s my maternal X chromosome at DNAPainter and how I utilized chromosome painting to push the identification of the ancestors whose X chromosome I inherited back an additional two generations.

Using that initial X chromosome match with my second cousin, shown by the arrow at bottom of the graphic, I mapped a large segment of my maternal X chromosome to my maternal great-grandparents.

By viewing the trees of subsequent X maternal matches, I was then able to push those common segments, shown painted directly above that match with the same color, back another two generations, to Joseph Hill, born in 1790, and Nabby Hall. I was able to do that based on the fact that other matches descend from Joseph and Nabby through different children, meaning we all triangulate on that common segment. I wrote about triangulation at DNAPainter, here.

I received no known X-DNA from my great-grandmother, Nora Kirsch, although a small portion of my X chromosome is still unassigned in yellow as “Uncertain.”

I received a small portion of my maternal X chromosome, in magenta, at left, from my maternal great-great-grandparents, John David Miller and Margaret Lentz.

The X chromosome is a powerful tool and can reach far back in time.

In some cases, the X, and other chromosomes can be inherited intact from one grandparent. I could have inherited my mother’s entire copy of her mother’s, or her father’s X chromosome based on random recombination, or not. As it turns out, I didn’t, and I know that because I’ve mapped my chromosomes to identify my ancestors based on common ancestors with my matches.

X-DNA Advanced Matches at FamilyTreeDNA

At FamilyTreeDNA, the Advanced Matches tab includes the ability to search for X matches, either within the entire database, or within specific projects. I find the project selection to be particularly useful.

For example, within the Claxton project, my father’s maternal grandmother’s line, I recognize my match, Joy, which provides me an important clue as to the possible common ancestor(s) of our shared segments.

Joy’s tree shows that her 4-times great-grandparents are my 3-times great-grandparents, meaning we are 4^th cousins once removed and share 17 cM of DNA on our X chromosome across two segments.

Don’t be deceived by the physical appearance of “size” on your chromosomes. The first segment that spans the centromere, or “waist” of the chromosome, above, is 10.29 cM, and the smaller segment at right is 7.02 cM. SNPs are not necessarily evenly distributed along chromosomes.

Remember, an X or other autosomal match doesn’t necessarily mean the entire match is contained in one segment so long as it’s large enough to be divided in two parts and survive the match threshold.

It’s worth noting that Joy and I actually share at least two different, unrelated ancestral lines, so I need to look at Joy’s blocked lines to see if one of those common ancestral lines is not a possibility for our X match. It’s important to evaluate all possible ancestors, plus the inheritance path to eliminate any lineage that involves a father to son inheritance on the X chromosome.

Last but not least, you may match on your X chromosome through a different ancestor than on other chromosomes. Every matching segment has its own individual history. It’s not safe to assume.

Now, take a look at your X chromosome matches at FamilyTreeDNA, 23andMe, and GedMatch. What will you discover?

Beethoven’s DNA Reveals Surprises – Does Your DNA Match?

Posted on March 23, 2023 by Roberta Estes

Beethoven’s DNA has been sequenced from a lock of his hair. That, alone, is amazing news – but that’s just the beginning!

The scientific paper was released this week, and the news media is awash with the unexpected surprises that Beethoven’s DNA has revealed for us. Better yet, his DNA is in the FamilyTreeDNA database and you just might match. Are you related to Beethoven?

His Y-DNA, mitochondrial DNA and autosomal DNA have been recovered and are available for matching.

You can check your autosomal results if you’ve taken a Family Finder test, or you can upload your DNA file from either AncestryDNA, 23andMe or MyHeritage to find out if you match Beethoven. Here are the download/upload instructions for each company.

But first, let’s talk about this amazing sequence of events (pardon the pun) and scientific discoveries!

Beethoven’s Genome is Sequenced

Everyone knows the famous, genius composer, Ludwig van Beethoven. He was born in 1770 in Bonn on the banks of the Rhine River and died in 1827 in Vienna. You can listen to a snippet of his music, here.

We are all about to know him even better.

Yesterday, amid much media fanfare and a press release, the genome and related findings about Beethoven were released by a team of renowned scientists in a collaborative effort. Research partners include the University of Cambridge, the Ira F. Brilliant Center for Beethoven Studies, the American Beethoven Society, KU Leuven, the University Hospital Bonn, the University of Bonn, the Beethoven-Haus Bonn, the Max Planck Institute for Evolutionary Anthropology and FamilyTreeDNA. I want to congratulate all of these amazing scientists for brilliant work.

Beethoven’s Hair Revelations

In the past, we were unable to retrieve viable DNA from hair, but advances have changed that in certain settings. If you’re eyeing grandma’s hair wreath – the answer is “not yet” for consumer testing. Just continue to protect and preserve your family heirlooms as described in this article.

Thankfully, Beethoven participated in the Victorian custom of giving locks of hair as mementos. Eight different locks of hair attributed to Beethoven were analyzed, with five being deemed authentic and one inconclusive. Those locks provided enough DNA to obtain a great deal of different types of information.

Beethoven’s whole genome was sequenced to a 24X coverage level, meaning the researchers were able to obtain 24 good reads of his DNA, providing a high level of confidence in the accuracy of the sequencing results.

What Was Discovered?

Perhaps the most interesting discovery, at least to genealogists, is that someplace in Beethoven’s direct paternal lineage, meaning his Y-DNA, a non-paternal event (NPE) occurred. The paper’s primary authors referred to this as an “extra-pair-paternity event” but I’ve never heard that term before.

Based on testing of other family members, that event occurred sometime between roughly 1572 and Ludwig’s conception in 1770. The reported lack of a baptismal record had already raised red flags with researchers relative to Beethoven’s paternity, but there is nothing to suggest where in the five generations prior to Ludwig von Beethoven that genetic break occurred. Perhaps testing additional people in the future will provide more specificity.

We also discovered that Beethoven was genetically predisposed to liver disease. He was plagued with jaundice and other liver-related issues for much of his later life.

Beethoven, prior to his death, left a handwritten directive asking his physicians to describe and publicize his health issues which included progressive hearing loss to the point of deafness, persistent gastrointestinal problems and severe liver issues that eventually resulted in his death. Cirrhosis of the liver was widely believed to be his cause of death.

In addition, DNA in the hair revealed that Beethoven had contracted Hepatitis B, which also affects the liver.

The combination of genetic predisposition to liver disease, Hepatitis B and heavy alcohol use probably sealed his fate.

Additional health issues that Beethoven experienced are described in the paper, published in Current Biology.

It’s quite interesting that during this analysis the team devised a method to use triangulated segments that they mapped to various geographic locations, as illustrated above in a graphic from the paper. Fascinating work!!!

As a partner in this research, Cambridge University created a beautiful website, including a video which you can watch, here.

Beethoven’s Later Years

This portrait of Beethoven was painted in 1820 just 7 years before his death, at 56 years of age. By this time, he had been completely deaf for several years, had stopped performing and appearing in public. Ironically, he still continued to compose, but was horribly frustrated and discouraged, even contemplating suicide. I can’t even fathom the depths of despair for a person with his musical genius to become deaf, slowly, like slow torture.

His personal life didn’t fare much better. In 1812, he wrote this impassioned love letter to his “Immortal Beloved” whose identity has never been revealed, if it was ever known by anyone other than Beethoven himself. The letter was never sent, which is why we have it today.

FamilyTreeDNA

FamilyTreeDNA, one of the research partners published a blog article, here.

The FamilyTreeDNA research team not only probed Beethoven’s genealogy, they tested people whose DNA should have matched, but as it turns out, did not.

Beethoven’s mitochondrial DNA haplogroup is H1b1+16,362C, plus a private mutation at C16,176T. Perhaps in the future, Beethoven’s additional private mutation will become a new haplogroup if other members of this haplogroup have it as well. If you have tested your mitochondrial DNA, check and see if Beethoven is on your match list. If you haven’t tested, now’s a great time.

According to the academic paper, Beethoven’s Y-DNA haplogroup is I-Z139, but when viewing Figure 5 in the paper, here, I noticed that Beethoven’s detailed haplogroup is given as I-FT396000, which you can see in the Discover project, here.

Viewing the Time Tree and the Suggested Projects, I noticed that there are four men with that haplogroup, some of whom are from Germany.

The ancestor’s surnames of the I-FT396000 men, as provided in public projects include:

Pitzschke (from Germany)
Hartmann (from Germany)
Stayler
Schauer (from Germany)

If your Y-DNA matches Beethoven at any level, you might want to upgrade if you haven’t taken the Big Y-700 test. It would be very interesting to see when and where your most recent common ancestor with Beethoven lived. You just never known – if you match Beethoven, your known ancestry might help unravel the mystery of Beethoven’s unknown paternal lineage.

Beethoven’s DNA is in the FamilyTreeDNA database for matching, including Y-DNA mitochondrial and autosomal results, so you just might match. Take a look! A surprise just might be waiting for you.
