Discover’s Ancient Connections – How Are You Related?

Posted on by

When FamilyTreeDNA released the new Mitotree, they also introduced their new mtDNA Discover tool, which is a series of 13 reports about each haplogroup, including one titled Ancient Connections.

Ancient Connections shows you ancient relatives from your direct matrilineal line through a mitochondrial DNA test or through a Y-DNA (preferably Big Y-700) test.

Ancient Connections help you connect the present to the past based on archaeological excavations around the world and DNA sequencing of remains. Ancient Connections links you through your DNA to ancient people, cultures, and civilizations that would be impossible to discover any other way. You don’t have to wonder if it’s accurate, or which line it came from, because you know based on the test you took. Discover’s Ancient Connections track the journey of your ancestors and relatives.

Ancient Connections can be very exciting – and it’s easy to get swept away on a wave of jubilation.

Are those people your ancestors, or relatives, or what? How do you know? How can you figure it out?

So let me just answer that question generally before we step through the examples, so you can unveil your own connections.

  • You are RELATED to both Ancient and Notable Connections. Notable Connections are famous or infamous people who have lived more recently, and their relatives have been tested to identify their haplogroups.
  • It’s VERY unlikely that Ancient Connections are your direct ancestors – but someone in the line that you share IS your ancestor.
  • Many factors enter into the equation of how you are related, such as the haplogroup(s), the timeframe, and the location.
  • The sheer number of people who were living at any specific time makes it very unlikely that any one person with that haplogroup actually was your direct ancestor. They are much more likely to be your distant cousin.

Factors such as whether you share the same haplogroup, similar locations, and the timeframe make a huge difference. Everyone’s situation is different with each Ancient Connection.

Ok, are you ready for some fun???

Let’s find out how to leverage these tools.

Ancient Connections

Ancient connections are fun and can also be quite useful for genealogy.

In this article, I’m going to use a mitochondrial DNA example because full sequence testers at FamilyTreeDNA just received their new Mitotree haplogroup. mtDNA Discover was released with Mitotree, so it’s new too. However, the evaluation process is exactly the same for Y-DNA.

Everyone’s results are unique, so your mileage absolutely WILL vary. What we are going to learn here is a step-by-step analytical process to make sure you’re hearing the message from your ancestors – and interpreting it correctly.

To learn about your new mitochondrial DNA haplogroup and haplotype, read the articles:

Radegonde Lambert

Let’s start with an Acadian woman by the name of Radegonde Lambert. She’s my ancestor, and I wrote about her years ago in the article, Radegonde Lambert (1621/1629-1686/1693), European, Not Native.

At the time, that article caused a bit of a kerfluffle, along with the article, Haplogroup X2b4 is European, Not Native American, because Radegonde’s X2b4 haplogroup had been interpreted by some to mean that her matrilineal ancestors were Native American.

That often happens when a genealogical line abruptly ends and hits a brick wall. What probably began with “I wonder if…”, eventually morphed into “she was Native,” when, in fact, she was not. In Radegonde’s case, it didn’t help any that her haplogroup was X2b4, and some branches of base haplogroup X2 are in fact Native, specifically X2a, However, all branches of X2 are NOT Native, and X2b, which includes X2b4, is not.

The Acadians were French people who established a colony in what is now Nova Scotia in the 1600s. They did sometimes intermarry with the Native people, so either Native or European heritage is always a possibility, and that is exactly why DNA testing is critically important. Let’s just say we’ve had more than one surprise.

I always reevaluate my own work when new data becomes available, so let’s look to see what’s happening with Radegonde Lambert now, with her new haplogroup and mtDNA Discover.

Sign on and Identify Your Haplogroup

You can follow along here, or sign on to your account at FamilyTreeDNA.

The first step is to take note of your new Mitotree haplogroup.

Your haplogroup badge is located near the bottom right of your page after signing in.

The tester who represents Radegonde Lambert has a Legacy Haplogroup of X2b4 and has been assigned a new Mitotree haplogroup of X2b4g.

Click Through to Discover

To view your personal Discover information, click on the Discover link on your dashboard.

You can simply enter a haplogroup in the free version of mtDNA Discover, but customers receive the same categories, but significantly more information if they sign in and click through.

You can follow along on the free version of Discover for haplogroups X2b4 here, and X2b4g here.

Clicking on either the Time Tree, or the Classic Tree shows that a LOT has changed with the Mitotree update.

Each tree has its purpose. Let’s look at the Classic Tree first.

The Classic Tree

I like the Classic Tree because it’s compact, detailed and concise, all in one. Radegonde Lambert’s new haplogroup, X2b4g is a subgroup of X2b4, so let’s start there.

Click on any image to enlarge

Under haplogroup X2b4, several countries are listed, including France. There are also 7 haplotype clusters, which tell you that those testers within the cluster all match each other exactly.

It’s worth noting that the little trowels (which I thought were shovels all along) indicate ancient samples obtained from archaeological digs. In the Discover tools, you’ll find them under Ancient Connections for that haplogroup. We will review those in a minute.

In Mitotree, haplogroup X2b4 has now branched several granular and more specific sub-haplogroups.

Radegonde Lambert’s new haplogroup falls below another new haplogroup, X2b4d’g, which means that haplogroup X2b4d’g is now the parent haplogroup of both haplogroups X2b4d and X2b4g. Both fall below X2b4d’g.

Haplogroup names that include an apostrophe mean it’s an umbrella group from which the two haplogroups descend – in this case, both X2b4d and X2b4g. Apostrophe haplogroups like X2b4d’g are sometimes referred to as Inner Haplogroups.

You can read more about how to understand your haplogroup name, here.

In this case, haplogroup X2b4d’g is defined by mutation G16145A, which is found in both haplogroups X2b4d and X2b4g. Both of those haplogroup have their own defining mutations in addition to G16145A, which caused two branches to form beneath X2b4d’g.

You can see that Radegonde Lambert’s haplogroup X2b4g is defined by mutation C16301T, but right now, that really doesn’t matter for what we’re trying to accomplish.

In descending order, for Radegonde, we have haplogroups:

  • X2b4
  • X2b4d’g
  • X2b4g

Your Match Page

Looking at the tester’s match page, Radegonde’s haplotype cluster number and information about the cluster are found below the haplogroup. You can view your cluster number on:

  • Your match page
  • The Match Time Tree beside your name and those of your matches in the same haplotype cluster
  • The Scientific Details – Variants page

I wrote about haplotype clusters, here.

Click on any image to enlarge

On your match page, which is where most people look first, you are in the same haplogroup and haplotype cluster with anyone whose circle is also checked and is blue. If the little circles are not checked and blue, you don’t share either that haplogroup, haplotype cluster, or haplogroup and haplotype cluster. If you share a haplotype cluster, you will always share the same haplogroup.

Haplotype clusters are important because cluster members match on exactly the same (but less stable) mutations IN ADDITION to haplogroup-defining (more stable) mutations.

However, you may also share an identifiable ancestor with people in different haplotype clusters. Mutations, and back mutations happen – and a lot more often at some mutation locations, which is why they are considered less stable. Normally, though, your own haplotype cluster will hold your closest genealogical matches.

In Discover, you can see that Radegonde’s haplotype cluster, F585777, displays three tester-supplied countries, plus two more. Click on the little plus to expand the countries.

What you’re viewing are the Earliest Known Ancestor (EKA) countries that testers have entered for their direct matrilineal ancestor.

Let’s hope they understood the instructions, and their genealogy information was accurate.

Notice that Canada and France are both probably quite accurate for Radegonde, based on the known history of the Acadians. There were only French and Native women living in Nova Scotia in the 1600s, so Radegonde had to be one or the other.

The US may be accurate for a different tester whose earliest known ancestor (EKA) may have been found in, say, Louisiana. Perhaps that person has hit a brick wall in the US, and that’s all they know.

The US Native American flag is probably attributable to the old “Native” rumor about Radegonde, and the tester didn’t find the Canadian First Nations flag in the “Country of Origin” dropdown list. Perhaps that person has since realized that Radegonde was not Native and never thought to change their EKA designation.

The little globe with “Unknown Origins” is displayed when the tester doesn’t select anything in the “Country of Origin.”

Unfortunately, this person, who knew when Radegonde Lambert lived, did not complete any additional information, and checked the “I don’t know this information” box. Either Canada, or France would have been accurate under the circumstances. If they had tracked Radegonde back to Canada and read about her history, they knew she lived in Canada, was Acadian, and therefore French if she was not Native. Providing location information helps other testers, whose information, in turn, helps you.

Please check your EKA, and if you have learned something new, PLEASE UPDATE YOUR INFORMATION by clicking on the down arrow by your user name in the upper right hand corner, then Account Settings, then Genealogy, then Earliest Known Ancestors.

Don’t hesitate to email your matches and ask them to do the same. You may discover that you have information to share as well. Collaboration is key.

Radegonde’s Discover Haplogroup

First, let’s take a look at Radegonde’s haplogroup, X2b4g, in Discover.

The Discover Haplogroup Story landing page for haplogroup X2b4g provides a good overview. Please READ this page for your own haplogroup, including the little information boxes.

The history of Radegonde’s haplogroup, X2b4g, is her history as well. It’s not just a distant concept, but the history of a woman who is the ancestor of everyone in that haplogroup, but long before surnames. Haplogroups are the only way to lift and peer behind the veil of time to see who our ancestors were, where they lived, and the cultures they were a part of.

We can see that Radegonde’s haplogroup, X2b4g, was born in a woman who lived about 300 CE, Common (or Current) Era, meaning roughly the year 300, which is 1700 years ago, or 1300 years before Radegonde lived.

  • This means that the tester shares a common ancestor with everyone, including any X2b4g remains, between now and the year 300 when haplogroup X2b4g was born.
  • This means that everyone who shares haplogroup X2b4g has the same common female ancestor, in whom the mutation that defines haplogroup X2b4g originated. That woman, the common ancestor of everyone in haplogroup X2b4g, lived about the year 300, or 1700 years ago.
  • Your common ancestor with any one individual in this haplogroup can have lived ANYTIME between very recently (like your Mom) and the date of your haplogroup formation.
  • Many people misinterpret the haplogroup formation date to mean that’s the date of the MRCA, or most recent common ancestor, of any two people. It’s not, the haplogroup formation date is the date when everyone, all people, in the haplogroup shared ONE ancestor.
  • The MRCA, or most recent common ancestor, is your closest ancestor in this line with any one person, and the TMRCA is the “time to most recent common ancestor.” It could be your mother, or if your matrilineal first cousin tested, your MRCA is your grandmother, and the TMRCA is when your grandmother was born – not hundreds or thousands of years ago.
  • Don’t discount mitochondrial DNA testing by thinking that your common ancestor with your matches (MRCA) won’t be found before the haplogroup birth date – the year 300 in Radegonde’s case. The TMRCA for all of Radegonde’s descendants is about 1621 when she was born.
  • The haplogroup birth date, 1700 years ago, is the common ancestor for EVERYONE in the haplogroup, taken together.
  • Mitochondrial DNA is useful for BOTH recent genealogy and also reveals more distant ancestors.
  • Looking back in time helps us understand where Radegonde’s ancestors lived, which cultures they were part of, and where.

There are two ways to achieve that: Radegonde’s upstream or parent haplogroups, and Ancient Connections.

Parent Haplogroups

X2b4g split from X2b4d’g, the parent haplogroup of BOTH X2b4d and X2b4g, around 3700 years ago, or about 1700 BCE (Before Common (or Current) Era).

Looking at either the Classic Tree, the Time Tree (above) or the Match Time Tree, you can see that haplogroup X2b4g has many testers, and none provide any locations other than France, Canada, the US, unknown, and one Native in the midst of a large haplotype cluster comprised of French and Canadian locations. Due to the size of the cluster, it’s only partially displayed in the screen capture above.

You can also see that sister haplogroup X2b4d split from X2b4d’g around the year 1000, and the ancestors of those two testers are reported in Norway.

Many, but not all of the X2b4g testers are descendants of Radegonde. Even if everyone is wrong and Radegonde is not French, that doesn’t explain the other matches, nor how X2b4g’s sister haplogroup is found in Norway.

Clearly, Radegonde isn’t Native, but there’s still more evidence to consider.

Let’s dig a little deeper using Radegonde’s Ancient Connections.

Ancient Connections

While ancestor and location information are user-provided, Ancient Connections are curated from scientifically published papers. There’s no question about where those remains were found.

When signed in to your account, if you’ve taken the mtFull Sequence test, clicking on the Ancient Connections tab in Discover shows a maximum of around 30 Ancient Connections. If you’re viewing the free version of Discover, or you’ve only tested at the HVR1 or HVR1+HVR2 levels, you’ll see two of your closer and one of your most distant Ancient Connections. It’s easy to upgrade to the mtFull.

In Discover, the first group of Ancient Connections are genetically closest to you in time, and the last connections will be your most distant. Some connections may be quite rare and are noted as such.

Please keep in mind that oldest, in this case, Denisova 8 and Sima de los Huesos, will never roll off your list. However, as new studies are released and the results are added to the tree, you may well receive new, closer matches. New results are being added with each Discover update.

It’s very exciting to see your Ancient Connections, but I need to say three things, loudly.

  1. Do NOT jump to conclusions.
  2. These remains are probably NOT YOUR ANCESTORS, but definitely ARE your distant cousins.
  3. Ancient Connections ARE wonderful hints, especially when taken together with each other and additional information.

It’s VERY easy to misinterpret Ancient Connections because you’re excited. I’ve done exactly that. To keep the assumption monster from rearing its ugly head, I have to take a breath and ask myself a specific set of questions. I step through the logical analysis process that I’m sharing with you.

The first thing I always want to know is where the genetically closest set of remains was found, when, and what we know about them, so let’s start there. Keep in mind that the closest remains genetically may not be the most recent set of remains to have lived. For example, my own haplogroup will be the closest genetically, but that person may have lived 2000 years ago. An Ancient Connection in a more distant haplogroup may have lived only 1000 years ago. The closest person genetically is NOT the same as the person who lived the most recently.

Our tester, Radegonde’s descendant, has no Ancient Connections in haplogroup X2b4g or X2b4d’g, but does have two in haplogroup X2b4, so let’s start there.

Discover provides a substantial amount of information about each set of ancient remains. Click on the results you want to view, and the information appears below.

Radegonde’s first Ancient Connection is Carrowkeel 534. The graphic shows the tester, the Ancient Connection being viewed, and their shared ancestor’s haplogroup. In this case, the shared ancestor haplogroup of Carrowkeel 534 and the tester is X2b4, who lived about 5000 years ago.

It’s very easy to look at Carrowkeel 534, become smitten, and assume that this person was your ancestor.

By Shane Finan – Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=35098411

It’s especially easy if you WANT that person to be your ancestor. Carrowkeel 534 was buried in a passage tomb in County Sligo, Ireland. I’ve been there.

However, don’t let your emotions get involved – at least not yet.

This is the first example of the steps that determine that these remains are NOT YOUR ANCESTOR.

  • Carrowkeel 534 was a male, and we all know that males do not pass on their mitochondrial DNA. Well, that’s an inconvenient fact.😊
  • There are two sets of X2b4 remains in Ancient Connections. Carrowkeel 534 remains are about 4600-5000 years old, and your common ancestor with them lived about 5000 years ago. However, Radegonde was French and migration from Ireland to France is not typical.
  • The other set of X2b4 remains, Ladoga 16, lived more recently, between the years of 900 and 1200 (or 800-1100 years ago), but they are found in Russia.
  • Radegonde’s parent haplogroup, X2b4d’g was born about 3700 years ago, which excludes the Russian remains from being Radegonde’s direct ancestor.
  • Radegonde’s common ancestor with both these sets of remains lived about 5000 years ago, but these remains were not found even close to each other.

In fact, these remains, if walking, are about 3299 km (2049 miles) apart, including two major water crossings.

  • Given that Radegonde is probably French, finding her ancestor around 5000 years ago in an Irish passage tomb in County Sligo, or in a location east of St. Petersburg, is extremely unlikely.

What IS likely, though, is that X2b4d’g descendants of your common ancestor with both sets of remains, 5000 years ago, went in multiple directions, meaning:

  • Radegonde’s ancestor found their way to France and along the way incurred the mutations that define X2b4d’g and X2b4g by the year 1600 when she lived, or about four hundred years ago.
  • Another X2b4 descendant found their way to what is today Ireland between 4600 and 5000 years ago
  • A third X2b4 descendant found their way to Russia between 800-1100 years ago, and 5000 years ago

If any question remains about the genesis of Radegonde’s ancestors being Native, Ancient Connections disproves it – BUT – there’s still an opportunity for misunderstanding, which we’ll see in a few minutes.

Ancient Connections Analysis Chart

I’ve created an analysis chart, so that I can explain the findings in a logical way.

Legend:

  • Hap = Haplogroup
  • M=male
  • F=female
  • U=unknown

Please note that ancient samples are often degraded and can be missing important mutations. In other words, the tree placement may be less specific for ancient samples. Every ancient sample is reviewed by FamilyTreeDNA’s genetic anthropologist before it’s placed on the tree.

Ancient samples use carbon dating to determine ages. Sometimes, the carbon date and the calculated haplogroup age are slightly “off.” The haplogroup age is a scientific calculation based on a genetic clock and is not based on either genealogy or ancient burials. The haplogroup age may change as the tree matures and more branches are discovered.

I’m dividing this chart into sections because I want to analyze the findings between groups.

The first entry is the earliest known ancestor of the current lineage – Radegonde Lambert, who was born about 1621, or roughly 400 years ago. I’ve translated all of the years into “years ago” to avoid any confusion.

If you wish to do the same, with CE (Current or Common Era) dates, subtract the date from 2000. 300 CE= (2000-300) or1700 years ago. With BCE dates, add 2000 to the BCE number. 1000 BCE= (1000+2000) or 3000 years ago.

Connection Identity Age Years Ago Location & Cultural Group Hap Hap Age Years Ago Shared Hap Shared Hap Age Years Ago

Ladoga 16 (M) 800-1100 Ladoga, Russia Fed – Viking Russia X2b4 5000 X2b4 5000
  • Age Years Ago – When the Ancient Connection lived
  • Hap Age Years Ago – When the haplogroup of the Ancient Connection (X2b4) originated, meaning was born
  • Shared Hap Age Years Ago – When the Shared Ancestor of everyone in the Shared Haplogroup originated (was born)

In this first section, the haplogroup of the Ancient Connections and the Shared Haplogroup is the same, but that won’t be the case in the following sections. Radegonde Lambert’s haplogroup is different than her shared haplogroup with the Ancient Connections.

Let’s assume we are starting from scratch with Radegonde.

The first question we wanted to answer is whether or not Radegonde is European, presumably French like the rest of the Acadians, or if she was Native. That’s easy and quick.

Native people crossed Beringia, arriving from Asia someplace between 12,000 and 25,000 years ago in multiple waves of migration that spread throughout both North and South America.

Therefore, given that the first two samples, Carrowkeel 534 and Ladoga 16, share haplogroup X2b4, an upstream haplogroup with Radegonde Lambert, and haplogroup X2b4 was formed around 5000 years ago, the answer is that Radegonde’s X2b4 ancestor, whoever that was, clearly lived in Europe, NOT the Americas.

According to Discover, Haplogroup X2b4:

  • Was formed about 5000 years ago
  • Has 16 descendant haplogroups
  • Has 29 unnamed lineages (haplotype clusters or individuals with no match)
  • Includes testers whose ancestors are from 23 countries

The Country Frequency map shows the distribution of X2b4, including all descendant haplogroups. Please note that the percentages given are for X2b4 as a percentage of ALL haplogroups found in each colored country. Don’t be misled by the relative physical size of the US and Canada as compared to Europe.

The table view shows the total number of self-identified locations of the ancestors of people in haplogroup X2b4 and all downstream haplogroups.

The Classic Tree that we looked at earlier provides a quick view of X2b4, each descendant haplogroup and haplotype cluster, and every country provided by the 331 X2b4 testers.

For the X2b4 Ancient Connections, we’ve already determined:

  • That Radegonde’s ancestors were not Native
  • Carrowkeel 534 is a male and cannot be Radegonde’s ancestor. It’s extremely likely that Carrowkeel 534’s mother is not Radegonda’s ancestor either, based on several factors, including location.
  • Based on dates of when Ladoga 16 lived, and because he’s a male, he cannot be the ancestor of Radegonde Lambert.

Radegonda’s haplogroup was formed long before Ladoga 16 lived. Each Ancient Connection has this comparative Time Tree if you scroll down below the text.

  • Both Carrowkeel and Ladoga share an ancestor with our tester, and Radegonde, about 5000 years ago.

Think about how many descendants the X2b4 ancestor probably had over the next hundreds to thousands of years.

  • We know one thing for sure, absolutely, positively – X2b4 testers and descendant haplogroups live in 32 countries. People migrate – and with them, their haplogroups.

What can we learn about the genealogy and history of Radegonde Lambert and her ancestors?

We find the same haplogroup in multiple populations or cultures, at different times and in multiple places. Country boundaries are political and fluid. What we are looking for are patterns, or sometimes, negative proof, which is often possible at the continental level.

X2b4, excluding downstream haplogroups, is found in the following locations:

  • Bulgaria
  • Canada (2)
  • Czech Republic
  • England (2)
  • Finland (2)
  • France (3)
  • Germany (4)
  • Portugal
  • Scotland (2)
  • Slovakia (2)
  • Sweden (2)
  • UK (2)
  • Unknown (11)
  • US (2)

Note that there are three people in France with haplogroup X2b4 but no more refined haplogroup.

Looking at X2b4’s downstream haplogroups with representation in France, we find:

  • X2b4a (none)
  • X2b4b (none)
  • X2b4b1 (1)
  • X2b4d’g (none)
  • X2b4d (none)
  • X2b4g (24) – many from Radegonde’s line
  • X2b4e and subgroups (none)
  • X2b4f (none)
  • X2b4j and subgroups (none)
  • X2b4k (none)
  • X2b4l (1)
  • X2b4m (none)
  • X2b4n and subgroups (none)
  • X2b4o (none)
  • X2b4p (none)
  • X2b4r (none)
  • X2b4+16311 (none)

I was hoping that there would be an Ancient Connection for X2b4, X2b4d’g, or X2b4g someplace in or even near France – because that makes logical sense if Radegonde is from France.

All I can say is “not yet,” but new ancient sites are being excavated and papers are being released all the time.

Ok, so moving back in time, let’s see what else we can determine from the next set of Ancient Connections. Haplogroup X2b1”64 was formed about 5050 years ago.

Connection Identity Age Years Ago Location & Cultural Group Hap Hap Age Years Ago Shared Hap Shared Hap Age Years Ago
Radegonde Lambert (F) 400 France or Canada X2b4g 1700
Carrowkeel 534 (M) 5100-4600 Sligo, Ireland – Neolithic Europe X2b4 5000 X2b4 5000
Ladoga 16 (M) 800-1100 Ladoga, Russia Fed – Viking Russia X2b4 5000 X2b4 5000

Bogovej 361 (F) 1000-1100 Lengeland, Denmark – Viking Denmark X2b1”64 5516-5259 X2b1”64 5050
Ladoga 410 (M) 800-1000 Leningrad Oblast, Russia – Viking Russia X2b1”64 5516-5259 X2b1”64 5050

Our first group ended with haplogroup X2b4, and our second group consists of haplogroup X2b1”64, the parent haplogroup of X2b4. X2b1”64 is a significantly larger haplogroup with many downstream branches found throughout Europe, parts of western Asia, the Levant, India, and New Zealand (which probably reflects a colonial era settler). The Country Frequency Map and Table are found here.

X2b1”64 is just slightly older than X2b4, but it’s much more widespread, even though they were born about the same time. Keep in mind that haplogroup origination dates shift as the tree is developed.

  • These seven individuals who share X2b1”64 as their haplogroup could be related to each other individually, meaning their MRCA, anytime between when they lived and when their haplogroup was formed.
  • The entire group of individuals all share the same haplogroup, so they all descend from the one woman who formed X2b1”64 about 5050 years ago. She is the shared ancestor of everyone in the haplogroup.

One X2b4 and one X2b1”64 individual are found in the same archaeological site in Russia. Their common ancestor would have lived between the time they both lived, about 800 years ago, to about 5000 years ago. It’s also possible that one of the samples could be incomplete.

A second X2b1”64 Ancient Connection is found in the Court Tomb in County Clare, Ireland, not far from the Carrowkeel 534 X2b4 site.

However, Monte Sirai is fascinating, in part because it’s not found near any other site. Monte Sirai is found all the way across France, on an island in the Tyrrhenian Sea.

It may be located “across France” today, but we don’t know that the Phoenician Monte Sirai site is connected with the Irish sites. We can’t assume that the Irish individuals arrived as descendants of the Monte Sirai people, even though it would conveniently fit our narrative – crossing France. Of course, today’s path includes ferries, which didn’t exist then, so if that trip across France did happen, it could well have taken a completely different path. We simply don’t know and there are very few samples available.

Three Ancient Connections are found in the Rössberga site in Sweden and another in  Denmark.

Adding all of the Ancient sites so far onto the map, it looks like we have two clusters, one in the northern latitudes, including Denmark, Sweden, and Russia, and one in Ireland with passage burials, plus one single Connection in Monte Sirai.

If I were to approximate a central location between all three, that might be someplace in Germany or maybe further east. But remember, this is 5000 years ago and our number of samples, as compared to the population living at the time is EXTREMELY LIMITED.

Let’s move on to the next group of Ancient Connections, who have different haplogroups but are all a subset of haplogroup X2.

The next several Ancient Connections have haplogroups that are a subgroup of haplogroup X2. These people lived sometime between 500 years ago in Hungary, and 8390-9250 years ago when Kennewick Man lived in the present-day state of Washington in the US. Kennewick Man merits his own discussion, so let’s set him aside briefly while we discuss the others.

The important information to be gleaned here isn’t when these people lived, but when Radegonde shared a common ancestor with each of them. The shared haplogroup with all of these individuals was born about 13,000 years ago.

Looking at the map again, and omitting both X2 samples, we can see that the descendants of that shared ancestor 13,000 years ago are found more widely dispersed.

Including these additional burials on our map, it looks like we have a rather large Swedish and Viking cluster, where several of the older burials occurred prior to the Viking culture. We have a Southeastern Europe cluster, our two Irish tomb burials, and our remaining single Monte Sirai Phoenician burial on the island of Sardinia.

Stepping back one more haplogroup to X2, which was born about the same time, we add a burial in India, and Kennewick Man.

The Migration Map

The Migration map in Discover provides two different features.

  • The first is the literal migration map for the various ancestral haplogroups as they migrated out of Africa, if in fact yours did, culminating in your base haplogroup. In this case, the base haplogroup is X2, which is shown with the little red circle placed by FamilyTreeDNA. I’ve added the red squares, text and arrows for emphasis.
  • The second feature is the mapped Ancient Connections, shown with little brown trowels. Clicking on each one opens a popup box.

After haplogroup X2 was formed, it split into haplogroups X2a and X2b.

The X2a group, Kennewick Man’s ancestors, made their way eastward, across eastern Russia to Beringia where they crossed into the Americas.

They either crossed Beringia, follow the Pacific coastline, or both, eventually making their way inland, probably along the Hood River, to where Kennewick Man was found some 2,800 years later on the banks of the Kennewick River.

The X2b group made their way westward, across western Europe to a location, probably France, where Radegonde Lamberts’ ancestors lived, and where Radegonde set sail for Nova Scotia.

After being separated for nearly 13,000 years, the descendants of the single woman who founded haplogroup X2 and lived someplace in central Asia around 13,000 years ago would find themselves on opposite coasts of the same continent.

So, no, Radegonde Lambert was not Native American, but her 600th matrilineal cousin or so, Kennewick Man, absolutely was.

Radegonde Lambert and Kennewick Man

Here’s where confirmation bias can rear its ugly head. If you’re just scanning the Ancient Connections and see Kennewick Man, it would be easy to jump to conclusions, leap for joy, slap a stamp of “confirmed Native American” on Radegonde Lambert, and never look further. And if one were to do that, they would be wrong.

Let’s work through our evaluation process using Discover.

Radegonde Lambert and Kinnewick Man, an early Native American man whose remains were found Kennewick, Washington in 1996, are both members of the broader haplogroup X2. Kennewick Man lived between 8290 and 9350 years ago, and their shared ancestor lived about 13,000 years ago – in Asia, where mitochondrial haplogroup X2 originated. This is the perfect example of one descendant line of a haplogroup, X2 in this case, going in one direction and a second one traveling in the opposite direction.

Two small groups of people were probably pursuing better hunting grounds, but I can’t help but think of a tundra version of the Hatfields and McCoys and cousin spats.

“I’m going this way. There are better fish on that side of the lake, and I won’t have to put up with you.”

“Fine, I’m going that way. There are more bears and better hunting up there anyway.”

Their wives, who are sisters, “Wait, when will I ever see my sister again?”

One went east and one went west.

X2a became Native American and X2b became European.

Looking back at our information about Kennewick Man, his haplogroup was born significantly before he lived.

He was born about 8390-9250 years ago, so let’s say 8820 years ago, and his haplogroup was born 10,500 years ago, so about 1680 years before he lived. That means there were many generations of women who carried that haplogroup before Kennewick Man.

Let’s Compare

Discover has a compare feature.

I want to Compare Radegonde Lambert’s haplogroup with Kennewick Man’s haplogroup X2a2’3’4^.

The Compare tool uses the haplogroup you are viewing, and you enter a second haplogroup to compare with the first.

The ancestral path to the shared ancestor, meaning their shared haplogroup, is given for each haplogroup entered. That’s X2 in this case. Then, from the shared haplogroup back in time to Mitochondrial Eve.

I prefer to view this information in table format, so I created a chart and rounded the haplogroup ages above X2.

More Ancient Connections

Radegonde Lambert’s matrilineal descendants have an additional dozen Ancient Connections that are found in upstream haplogroup N-8701. Their shared ancestors with Radegonde reach back to 53,000 years ago in a world far different than the one we inhabit today. I’m not going to list or discuss them, except for one.

Zlatý kůň Woman

Zlatý kůň Woman lived some 43,000 years ago and her remains were discovered in the Czech Republic in 1950.

Believed to be the first anatomically modern human to be genetically sequenced, she carried about 3% Neanderthal DNA. Europeans, Asians and indigenous Americans carry Neanderthal DNA as well.

Unlike many early remains, Zlatý kůň Woman’s facial bones have been scanned and her face approximately reconstructed.

There’s something magical about viewing a likeness of a human that lived more than 40,000 years ago, and to whom I’m at least peripherally related.

Like all other Ancient Connections, it’s unlikely that I descend from Zlatý kůň Woman herself, but she is assuredly my very distant cousin.

What else do we know about Zlatý kůň Woman? Quoting from her Ancient Connection:

She lived during one of the coldest periods of the last ice age, surviving in harsh tundra conditions as part of a small hunter-gatherer group. She died as a young adult, though the cause of death remains unknown.

Her brain cavity was larger than that of modern humans in the comparative database, another trait showing Neanderthal affinity. While the exact colors of her features cannot be determined from available evidence, researchers created both a scientific grayscale model and a speculative version showing her with dark curly hair and brown eyes.

Zlatý kůň Woman may or may not have direct descendants today, but her haplogroup ancestors certainly do, and Radegonde Lambert is one of them, which means Radegonde’s matrilineal ancestors and descendants are too.

Ancient Connections for Genealogy

While Ancient Connections are fun, they are more than just amusing.

You are related through your direct matrilineal (mitochondrial) line to every one of your mtDNA Discover Ancient Connections. Everyone, males and females, can take a mitochondrial DNA test.

I find people to test for the mitochondrial DNA of each of my ancestral lines – like Radegonde Lambert, for example. I wrote about various methodologies to find your lineages, or people to test for them, in the article, Lineages Versus Ancestors – How to Find and Leverage Yours.

Radegonde’s mitochondrial DNA is the only key I have into her past, both recent and distant. It’s the only prayer I have of breaking through that brick wall, now or in the future.

Interpreted correctly, and with some luck, the closer Ancient Connections can provide genealogical insight into the origins of our ancestors. Not just one ancestor, but their entire lineage. While we will never know their names, we can learn about their cultural origins – whether they were Vikings, Phoenicians or perhaps early Irish buried in Passage Graves.

On a different line, an Ancient Connection burial with an exact haplogroup match was discovered beside the Roman road outside the European town where my ancestral line was believed to have been born.

Ancient Connections are one small glimpse into the pre-history of our genetic line. There are many pieces that are missing and will, in time, be filled in by ancient remains, Notable Connections, and present-day testers.

Check your matches and your Ancient Connections often. You never know when that magic piece of information you desperately need will appear.

What is waiting for you?

RootsTech 2025 – The Year of Discover and the New Mitotree

Posted on by
3

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.

Million Mito Team, left to right, Goran Runfeldt, Dr. Paul Maier, me, Dr. Miguel Vilar, Bennett Greenspan, John Detsikas

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 12th.

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!

Six Ways to Figure Out How We’re Related

Posted on by
5

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

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

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

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

Come along for a step-by-step guide!

Shared Matches

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

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

Bucketing and Sides

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

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

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

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

Surnames and Locations

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

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

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

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

X-DNA

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

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

Clustering Technology – AutoClusters, the Matrix and DNAPainter

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

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

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

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

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

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

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

Theories of Family Relativity and ThruLines

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

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

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

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

Bonus – Y-DNA and Mitochondrial DNA at FamilyTreeDNA

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

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

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

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

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

Tune In

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

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

You can watch the webinar, here.

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

A Legacy Family Tree Webinar subscription normally costs $49.95 per year, but through the end of September, there’s a coupon code good for 20% off. Just click here, then enter webtember24 at the checkout.

Enjoy!

FamilyTreeDNA 2023 Update – Past, Present and Future

Posted on by
14

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.

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

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:

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.

Holiday DNA Sales Are Here!!!

Posted on by
Reply

I apologize for the brevity of this posting, but I came home from the FamilyTreeDNA Conference this past weekend with “conference crud.”

I’ll catch you up on that great conference later, but sales won’t wait, and the holiday sales have already begun. This is a great time to order. These prices are the lowest ever.

MyHeritage

The MyHeritage autosomal test is only $36, and shipping is free if you order two or more DNA tests. That’s a GREAT deal. Click here to order.

If you’ve already tested elsewhere, you can upload your raw DNA file from that vendor to MyHeritage, here. I’ve provided step-by-step instructions, here. After you’ve uploaded, be sure to purchase the $29 unlock for advanced autosomal features, including the MyHeritage chromosome browser and Theories of Family Relativity, which shows you how you connect with DNA matches who share the same ancestor in MyHeritage’s collection of 52 million trees.

If you’re new to MyHeritage, you can also purchase a data or records subscription here, including a free trial.

I use this combination of DNA, trees, and tools almost daily and love that MyHeritage sends me regular record matches from their billions of genealogy records.

FamilyTreeDNA

Every test is on sale at FamilyTreeDNA.

As you know, FamilyTreeDNA provides Y-DNA, mitochondrial, and autosomal testing through their Family Finder test. They also accept autosomal DNA file uploads from Ancestry and MyHeritage. You’ll find easy download and upload instructions for each vendor, here. The advanced feature unlock is on sale now for just $9!

You can order each test individually or bundle tests for a better price.

Note that the introductory Y-DNA 37-marker test is available for $99, and can later be upgraded to the Big-Y test. However, the Big Y-700 is on sale for $399 which is a great price. Y-DNA testing unlocks your paternal ancestor’s history revealed in FamilyTreeDNA‘s world-class Discover tools.

If you’ve already tested at FamilyTreeDNA and would like to add another test for yourself or upgrade, say to the Big-Y test, just click here, sign on, and click on the Add Ons and Upgrade button in the upper right-hand corner.

I hope I’m not spilling the beans, but all sale prices, including upgrades and autosomal transfer unlocks, are shown below:

Genealogy Goals

The holidays are coming! Take a look at what you need for your genealogy.

I decided a long time ago it’s absolutely fine to “gift myself” with purchases and upgrades for my cousins. Especially the Big Y-700 at FamilyTreeDNA and the mitochondrial DNA test, which is vastly underutilized. This helps my genealogy immensely, as well as theirs. Most people are happy to swab, especially if you’re doing the genealogy work.

My goal is to:

  • Have the autosomal DNA of each of my family members and cousins in both databases that provide chromosome browsers so that I can confirm ancestors at FamilyTreeDNA and MyHeritage.
  • Find male cousins to test for the Y-DNA, the surname lineage of each of my ancestral lines. Males who descend paternally from each male ancestor can usually be tracked by their surname.
  • Mitochondrial DNA for each of my ancestors. For mitochondrial DNA testing, we need testers descended through all females from each female ancestor, although males in the current generation can test. Everyone has their mother’s direct matrilineal line mitochondrial DNA.

To find testing candidates for your lineages, check projects at FamilyTreeDNA, autosomal matches at all vendors, your ancestors at WikiTree, ThruLines at Ancestry, even though ThruLines is still having issues, and Theories of Family Relativity at MyHeritage.

With DNAtests on sale right now, this is a great time to purchase tests at MyHeritage and FamilyTreeDNA.

DNA: In Search Of…Your Grandparents

Posted on by
15

Are you searching for an unknown relative or trying to unravel and understand unexpected results? Maybe you discovered that one or both of your parents is not your biological parent. Maybe one of your siblings might be a half-sibling instead. Or maybe you suddenly have an unexpected match that looks to be an unknown close relative, possibly a half-sibling. Perhaps there’s a close match you can’t place.

Or, are you searching for the identity of your grandparent or grandparents? If you’re searching for your parent or parents, often identifying your grandparents is a necessary step to narrow the parent-candidates.

I’ve written an entire series of “In Search of Unknown Family” articles, permanently listed together, here. They will step you through the search process and help you understand how to unravel your results. If you’re new, reading these, in order, before proceeding, would be a good idea.

Identifying a Grandparent

I saved this “grandparents” article for later in the series because you will need the tools and techniques I’ve introduced in the earlier articles. Identifying grandparents is often the most challenging of any of the relationships we’ve covered so far. In part because each of those four individuals occupies a different place in your tree, meaning their X, Y-DNA and mitochondrial DNA is carried by different, and not all, descendants. This means we sometimes have to utilize different tools and techniques.

If you’re trying to identify any of your four grandparents, females are sometimes more challenging than males.

Why?

Women don’t have a Y chromosome to test. This can be a double handicap. Female testers can’t test a Y chromosome, and maternal ancestors don’t have a Y chromosome to match.

Of course, every circumstance differs. You may not have a male to test for paternal lines either.

The maternal grandfather can be uniquely challenging, because two types of DNA, Y-DNA and mitochondrial DNA matching are immediately eliminated for all testers.

While I’ve focused on the maternal grandfather in this example, these techniques can be utilized for all four grandparents as well as for parents. At the end, I’ll review other grandparent relationships and additional tools you might be able to utilize for each one.

In addition to autosomal DNA, we can also utilize mitochondrial DNA, Y-DNA and sometimes X DNA in certain situations.

Testing, Tests and Vendors

As you recall, only men have a Y chromosome (blue arrow), so only genetic males can take a Y-DNA test. Men pass their Y chromosome from father to son in each generation. Daughters don’t receive a Y chromosome.

Everyone has their mother’s mitochondrial DNA (pink arrow.) Women pass their mitochondrial DNA to both sexes of their children, but only females pass it on. In the current generation, represented by the son and daughter, above, the mother’s yellow heart-shaped mitochondrial DNA is inherited by both sexes of her children. In the current generation, males and females can both test for their mother’s mitochondrial DNA.

Of course, everyone has autosomal DNA, inherited from all of their ancestral lines through at least the 5th or 6th generation, and often further back in time. Autosomal DNA is divided in half in each generation, as children inherit half of each parents’ autosomal DNA (with the exception of the X chromosome, which males only inherit from their mother.)

The four major vendors, Ancestry, 23andMe, FamilyTreeDNA and MyHeritage sell autosomal DNA tests, but only FamilyTreeDNA sells Y-DNA and mitochondrial DNA tests.

Only 23andMe and FamilyTreeDNA report X matching.

All vendors except Ancestry provide segment location information along with a chromosome browser.

You can read about the vendor’s strengths and weaknesses in the third article, here.

Ordering Y and Mitochondrial DNA Tests

If you’re seeking the identities of grandparents, the children and parents, above, can test for the following types of DNA in addition to autosomal:

Person in Pedigree Y-DNA Mitochondrial
Son His father’s blue star His mother’s pink heart
Daughter None Her mother’s pink heart
Father His father’s blue star His mother’s gold heart
Mother None Her mother’s pink heart

Note that none of the people shown above in the direct pedigree line carry the Y-DNA of the green maternal grandfather. However, if the mother has a full sibling, the green “Male Child,” he will carry the Y-DNA of the maternal grandfather. Just be sure the mother and her brother are full siblings, because otherwise, the brother’s Y-DNA may not have been inherited from your mother’s father. I wrote about full vs half sibling determination, here.

Let’s view this from a slightly different perspective. For each grandparent in the tree, which of the two testers, son or daughter, if either, carry that ancestor’s DNA of the types listed in the columns.

Ancestor in Tree Y-DNA Mitochondrial DNA Autosomal DNA X DNA
Paternal Grandfather Son Neither Son, daughter Neither
Paternal Grandmother Has no Y chromosome None (father has it, doesn’t pass it on to son or daughter) Son, daughter Daughter (son does not receive father’s X chromosome)
Maternal Grandfather Neither Neither Son, daughter Son, daughter (potentially)
Maternal Grandmother Has no Y chromosome Son, daughter Son, daughter Son, daughter (potentially)

Obtaining the Y-DNA and mitochondrial DNA of those grandparents from their descendants will provide hints and may be instrumental in identifying the grandparent.

FamilyTreeDNA

You’ll need to order Y-DNA (males only) and mitochondrial DNA tests separately from autosomal DNA tests. They are three completely different tests.

At FamilyTreeDNA, the autosomal DNA test is called Family Finder to differentiate it from their Y-DNA and mitochondrial DNA tests.

Their autosomal test is called Family Finder whether you order a test from FamilyTreeDNA, or upload your results to their site from another vendor (instructions here.)

I recommend ordering the Big Y-700 Y-DNA test if possible, and if not, the highest resolution Y-DNA test you can afford. The Big Y-700 is the most refined Y-DNA test available, includes multiple tools and places Big Y-700 testers on the Time Tree through the Discover tool, providing relatively precise estimates of when those men shared a common ancestor. If you’ve already purchased a lower-precision Y-DNA test at FamilyTreeDNA, you can easily upgrade.

I wrote about using the Discover tool here. The recently added Group Time Tree draws a genetic Y-DNA tree of Big-Y testers in common projects, showing earliest known ancestors and the date of the most recent common ancestor.

You need to make sure your Family Finder, mitochondrial DNA and Y-DNA (if you’re a male) tests are ordered from the same account at FamilyTreeDNA.

You want all 3 of your tests on the same account (called a kit number) so that you can use the advanced search features that display people who match you on combinations of multiple kinds of tests. For example, if you’re a male, do your Y-DNA matches also match you on the autosomal Family Finder test, and if so, how closely? Advanced matching also provides X matching tools.

X DNA is included in autosomal tests. X DNA has a distinct matching pattern for males and females which makes it uniquely useful for genealogy. I wrote about X DNA matching here.

If you upload your autosomal results to FamilyTreeDNA from another company, you’re only uploading a raw DNA file, not the DNA itself, so FamilyTreeDNA will need to send you a swab kit to test your Y-DNA and mitochondrial DNA. If you upload your autosomal DNA, simply sign in to your kit, purchase the Y-DNA and/or mitochondrial DNA tests and they will send you a swab kit.

If you test directly at FamilyTreeDNA, you can add any test easily by simply signing in and placing an order. They will use your archived DNA from your swab sample, as long as there’s enough left and it’s of sufficient quality.

Fish In All Ponds

The first important thing to do in your grandparent search is to be sure you’re fishing in all ponds. In other words, be sure you’ve tested at all 4 vendors, or uploaded files to FamilyTreeDNA and MyHeritage.

When you upload files to those vendors, be sure to purchase the unlock for their advanced tools, because you’re going to utilize everything possible.

If you have relatively close matches at other vendors, ask if they will upload their files too. The upload is free. Not only will they receive additional matches, and another set of ethnicity results, their results will help you by associating your matches with specific sides of your family.

Why Order Multiple Tests Now Instead of Waiting?

I encourage testers to order their tests at the beginning of their journey, not one at a time. Each new test from a vendor takes about 6-8 weeks from the time you initially order – they send the test, you swab or spit, return it, and they process your DNA. Of course, uploading takes far less time.

If you’re adding elapsed time, two autosomal tests (Ancestry and 23andMe), two uploads (FamilyTreeDNA and MyHeritage,) a Y-DNA and a mitochondrial DNA test, if all purchased serially, one after the other, means you’ll be waiting about 6-8 months.

Do you want to wait 6-8 months? Can you afford to?

Part of that answer has to do with what, exactly, you’re seeking.

A Name or Information?

Are you seeking the name of a person, or are you seeking information about that person? With grandparents, you may be hoping to meet them, and time may be of the essence. Time delayed may not be able to be recovered or regained.

Most people don’t just want to put a name to the person they are seeking – they want to learn about them. You will have different matches at each company. Even after you identify the person you seek, the people you match at each company may have information about them, their photos, know about their life, family, and their ancestors. They may be able and willing to facilitate an introduction if that’s what you seek.

One cousin that I assisted discovered that his father had died just 6 weeks before he made the connection. He was heartsick.

Having data from all vendors simultaneously will allow you to compile that data and work with it together as well as separately. Using your “best” matches at each company, augmented by both Y-DNA and mitochondrial DNA can make MUCH shorter work of this search.

Your Y-DNA, if you’re a male will give you insights into your surname line, and the Big-Y test now comes with estimates of how far in the past you share a common ancestor with other men that have taken the Big-Y test. This can be a HUGE boon to a male trying to figure out his surname line.

Y-DNA and mitochondrial DNA, respectively, will eliminate many people from being your mother or father, or your direct paternal or direct maternal line ancestor. Both provide insights into which population and where that population originated as well. In other words, it provides you lineage-specific information not available elsewhere.

Your Y-DNA and mitochondrial DNA can also provide critically important information about whether that direct line ancestor belonged to an endogamous population, and where they came from.

Strategies

You may be tempted to think that you only need to test at one vendor, or at the vendor with the largest database, but that’s not necessarily true.

Here’s a table of my closest matches at the 4 vendors.

Vendor Closest Maternal Closest Paternal Comments
Ancestry 1C, 1C1R Half 1C, 2C I recognized both of the maternal and neither of the paternal.
23andMe 2C, 2C 1C1R, half-gr-niece Recognized both maternal, one paternal
MyHeritage Mother uploaded, 1C Half-niece, half 1C Recognized both maternal, one paternal
FamilyTreeDNA Mother tested, 1C1R Parent/child, half-gr-niece Recognized all 4

To be clear, I tested my mother at FamilyTreeDNA before she passed away, but if I was an adoptee searching for my mother, that’s the first database she would be in. As her family, we were able to order the Family Finder test from her archived DNA after she had passed away. I then uploaded her DNA file to MyHeritage, but she’ll never be at either 23andMe or Ancestry because they don’t accept uploads and she clearly can’t test.

Additionally, being able to identify maternal matches by viewing shared matches with my mother separates out close matches from my paternal side.

Let’s put this another way, I stand a MUCH BETTER chance of unraveling this mystery with the combined closest matches of all 4 databases instead of the top ones from just one database.

I’m providing analysis methodologies for working with results from all of the vendors together, in case your answer is not immediately obvious. Taking multiple tests facilitates using all of these tools immediately, not months later. Solving the puzzle sooner means you may not miss valuable connection opportunities.

You may also discover that the door slams shut with some people, but another match may be unbelievably helpful. Don’t unnecessarily limit your possibilities.

Here’s the testing and upload strategy I recommend.

What When Ancestry 23andMe MyHeritage FamilyTreeDNA GEDmatch
Order autosomal test Initially Yes Yes Upload Upload Upload
Order Big-Y DNA test if male Initially Yes
Order mitochondrial DNA test Initially Yes
Upload free autosomal file From Ancestry or 23andMe Yes Yes Yes
Unlock Advanced Tools When upload file $29 $19 $9.95 month
Includes X Matching No Yes No Yes Yes
Chromosome Browser, segment location information No Yes Yes Yes Yes

When you upload a DNA file to a vendor site, only upload one file per site, per tester. Otherwise, multiple tests simply glom up everyone’s match list with multiple matches to the same person and can be very confusing.

  • One person took an autosomal test at a company that accepts uploads, forgot about it, uploaded a file from another vendor later, and immediately thought she had found her parent. She had not. She “found” herself.
  • Another person though she had found two sisters, but one person had uploaded their own file from two different vendors.

Multiple vendor sites reveal multiple close matches to different people which increase your opportunity to discover INFORMATION about your family, not just the identity of the person.

Match Ranges

Given that we are searching for an unknown maternal grandfather, your mother may not have had any (known) full siblings. The “best” match would be to a full or half siblings to your parents, or their descendants, depending on how old your grandparents would be.

Let’s take the “worst case” scenario, meaning there are no full siblings AND there are many possible generations between you and the people you may match.

Now, let’s look at DNAPainter’s Shared cM tool.

You’re going to be looking for someone who is either your mother’s half sibling on her father’s side, or who is a full sibling.

If your mother is adopted, it’s possible that she has or had full siblings. If your mother was born circa 1920, it’s likely that you will be matching the next generation, or two, or three.

However, if your mother was born later, you could be matching her siblings directly.

I’m going to assume half siblings for this example, because they are more difficult than full siblings.

Full sibling relationships for your mother’s siblings are listed at right. Your full aunt or uncle at top, then their descendant generations below.

At left, in red, are the half-sibling relationships and the matching amounts.

You can see that if you’re dealing with half 1C3R (half first cousin three times removed,) you may not match.

Therefore, in order to isolate matches, it’s imperative to test every relevant relative possible.

Who’s Relevant for DNA Testing?

Who is relevant to test If you’re attempting to identify your maternal grandfather?

The goal is to be able to assign matches to the most refined ancestor possible. In other words, if you can assign someone to either your grandmother’s line, or your grandfather’s line, that’s better than assigning the person to your grandparents jointly.

Always utilize the tests of the people furthest up the tree, meaning the oldest generations. Their DNA is less-diluted, meaning it has been divided fewer times. Think about who is living and might be willing to test.

You need to be able to divide your matches between your parents, and then between your grandparents on your mother’s side.

  • Test your parents, of course, and any of their known siblings, half or full.
  • If those siblings have passed away, test as many of their children as you can.
  • If any of your grandparents are living, test them
  • If BOTH of your grandparents on the same side aren’t available to test, test any, preferably all, living aunts or uncles.
  • If your maternal grandmother had siblings, test them or their descendants if they are deceased.
  • If your parents are deceased, test your aunts, uncles, full siblings and half-siblings on your mother’s side. (Personally, I’d test all half-siblings, not just maternal.)
  • Half-siblings are particularly valuable because there is no question which “side” your shared DNA came from. They will match people you don’t because they received part of your parent’s DNA that you did not.

Furthermore, shared matches to half-siblings unquestionably identify which parent those matches are through.

Essentially, you’re trying to account for all matches that can be assigned to your grandparents whose identities you know – leaving only people who descend from your unknown maternal grandfather.

Testing your own descendants will not aid your quest. There is no need to test them for this purpose, given that they received half of your DNA.

I wrote about why testing close relatives is important in the article Superpower: Your Aunts’ and Uncles’ DNA is Your DNA Too – Maximize Those Matches!

Create or Upload a Tree

Three of the four major vendors, plus GEDMatch, support and utilize family trees.

You’ll want to either upload or create a tree at each of the vendor sites.

You can either upload a GEDCOM file from your home computer genealogy software, or you can create a tree at one of the vendors, download it, and upload to the others. I described that process at Ancestry, here.

Goal

Your goal is to work with your highest matches first to determine how they are related to you, thereby eliminating matches to known lineages.

Assuming you’re only searching for the identity of one grandparent, it’s beneficial to have done enough of your genealogy on your three known grandparents to be able to assign matches from those lines to those sides.

Step 1 is to check each vendor for close matches that might fall into that category.

The Top 15 at Each Vendor

Your closest several autosomal matches are the most important and insightful. I begin with the top 15 autosomal results at each vendor, initially, which provides me with the best chance of meaningful close relationship discoveries.

Create a Spreadsheet or Chart

I hate to use that S word (spreadsheet), because I don’t want non-technical people to be discouraged. So, I’m going to show you how I set up a spreadsheet and you can simply create a chart or even draw this out on paper if you wish.

I’ve color-coded columns for each of my 4 grandparents. The green column is the target Maternal Grandfather whose identity I’m seeking.

I match our first example; Erik, at 417 cM. Based on various pieces of information, taken together, I’ve determined that I’m Erik’s half 1C1R. His 8 great-grandparent surnames, or the ones he has provided, indicate that I’m related to Eric on my paternal grandfather’s line.

You’ll want to record your closest matches in this fashion.

Let’s look at how to find this information and work with the tools at the individual vendors.

23andMe

Let’s start at 23andMe, because they create a potential genetic tree for you, which may or may not be accurate.

I have two separate tests at 23andMe. One is a V3 and one is a V4 test. I keep one in its pristine state, and I work with the second one. You’ll see two of “me” in the tree, and that’s why.

23andMe makes it easy to see estimated relationships, although they are not always correct. Generally, they are close, and they can be quite valuable.

Click on any image to enlarge

The maternal and paternal “sides” may not be positioned where genealogists are used to seeing them. Remember, 23andMe has no genealogy trees, so they are attempting to construct a genetic tree based on how people are related to you and to each other, with no prior knowledge. They do sometimes have issues with half-relationships, so I’d encourage you to use this tree to isolate people to the three grandparents you know.

In my case, I was able to determine the maternal and paternal sides easily based on known cousins. This is the perfect example of why it’s important to test known relatives from both sides of your family.

My paternal side, at right, in blue, was easy because I recognized my half-sister’s family, and because of known cousins who I recognized from having tested elsewhere. I’ve worked with them for years. The blue stars show people I could identify, mostly second cousins.

My maternal side is at left, in red. Normally, for genealogists, the maternal side is at right, and the paternal at left, so don’t make assumptions, and don’t let this positioning throw you.

I’m pretending I don’t know who my maternal grandfather is. I was able to identify my maternal grandmother’s side based on a known second cousin.

That leaves my target – my maternal grandfather’s line.

All of the matches to the left of the red circle would, by process of elimination, be on my maternal grandfather’s side.

The next step would be to figure out how the 5 people descending from my maternal grandfather’s line are related to each other – through which of their ancestors.

On the DNA Relatives match list, here’s what needs to be checked:

  • Do your matches share surnames with you or your ancestors?
  • Do they show surnames in common with each other?
  • Is there a common location?
  • Birth year which helps you understand their potential generation.
  • Did they list their grandparents’ birthplaces?
  • Did they provide a family tree link?
  • Do they also match each other using the Relatives in Common feature?
  • Do they triangulate, indicated by “DNA Overlap” in Relatives in Common?
  • Who else is on the Relatives in Common list, and what do they have in common with each other?
  • Looking at your Ancestry Composition compared with theirs, what are your shared populations, and are they relevant? If you are both 100% European, then shared populations aren’t useful, but if both people share the same minority ancestry, especially on the same segments, it may indeed be relevant – especially if it can’t be accounted for on the known sides of the family.

Reach out to these people and see what they know about their genealogy, if they have tested elsewhere, and if they have a genealogy tree someplace that you can view.

If they can tell you their grandparents’ names, birth and death dates and locations, you can check public sources like WikiTree, FamilySearch and Geni, or build trees for them. You can also use Newspaper resources, like Newspapers.com, NewspaperArchive and the newspapers at MyHeritage.

I added the top 15 23andMe matches into the spreadsheet I created.

You’ll notice that not many people at 23andMe enter surnames. However, if you can identify individuals from your 3 known lines, you can piggyback the rest by using Relatives in Common in conjunction with the genetic tree placement.

Be sure to check all the people that are connected to the target line in your genetic tree.

You’ll want to harvest your DNA segments to paint at DNAPainter if you don’t solve this mystery with initial reviews at each vendor.

Ancestry

Let’s move to Ancestry next.

At Ancestry, you’ll want to start with your closest matches on your match list.

Ancestry classifies “Close Matches” as anyone 200 cM or greater, which probably won’t reach as far down as the matches we’ll want to include.

Some of the categories in the Shared cM Chart from DNAPainter, above, don’t work based on ages, so I’ve eliminated those. I also know, for example, that someone who could fall in the grandparent/grandchild category (blue star,) in my case, does not, so must be a different relationship.

Second cousins, who share great-grandparents, can be expected to share about 229 cM of DNA on average, or between 41 and 592 cM. First cousins share 866 cM, and half first cousins share 449 cM on average.

I have 13 close matches (over 200 cM), but I’m including my top 15 at each vendor, so I added two more. You can always go back and add more matches if necessary. Just keep in mind that the smaller the match, the greater the probability that it came from increasingly distant generations before your grandparents. Your sweet spot to identify grandparents is between 1C and 2C.

I need to divide my close matches into 4 groups, each one equating to a grandparent. Record this on your spreadsheet.

You can group your matches at Ancestry using colored dots, which means you can sort by those groups.

You can also select a “side” for a match by clicking on “Yes” under the question, “Do you recognize them?”

Initially, you want to determine if this person is related to you on your mother’s or father side, and hopefully, through which grandparent.

Recently, Ancestry added a feature called SideView which allows testers to indicate, based on ethnicity, which side is “parent 1” and which side is “parent 2.” I wrote about that, here.

Make your selection, assuming you can tell which “side” of you descends from which parent based on ethnicity and/or shared matches. How you label “parent 1,” meaning either maternal or paternal, determines how Ancestry assigns your matches, when possible.

Using these tools, which may not be completely accurate, plus shared matches with people you can identify, divide your matches among your three known grandparents, meaning that the people you cannot assign will be placed in the fourth “unknown” column.

On my spreadsheet, I assign all of my closest matches to one of my grandparents. Michael is my first cousin (1C) and we share both maternal grandparents, so he’s not helpful in the division because he can’t be assigned to only one grandparent.

The green maternal grandfather is who I’m attempting to identify.

There are 4 people, highlighted in yellow, who don’t fall into the other three grandparent lines, so they get added to the green column and will be my focus.

I would be inclined to continue adding matches using a process known as the Leeds Method, until I had several people in each category. Looking back at the DNAPainter cM chart, at this point, we don’t have anyone below 200 cM and the matches we need might be below that threshold. The more matches you have to work with, the better.

At Ancestry, you cannot download your matches into a spreadsheet, nor can you work with other clustering tools such as Genetic Affairs, so you’ll have to build out your spreadsheet manually.

Check for the same types of information that I reviewed at 23andMe:

  • Review trees, if your matches have them, minimally recording the surnames of their 8 great-grandparents.
  • Review shared matches, looking for common names in the trees in recent generations.
  • View shared matches with people with whom you have a “Common Ancestor” indication, which means a ThruLine. You won’t have Thrulines with your target grandparent, of course, but Thrulines will allow you to place the match in one of the other columns. I wrote about ThruLines here, here and here.
  • ThruLines sometimes suggests ancestors based on other people’s trees, so be EXCEEDINGLY careful with potential ancestor suggestions. That’s not to say you should discount those suggestions. Just treat them as tree hints that may have been copy/pasted hundreds of times, because that’s what they are.

I make notes on each match so I can easily see the connection by scanning without opening the match.

Now, I have a total of 30 entries on my spreadsheet, 15 from 23and Me and 15 from Ancestry.

Why Not Use Autosclusters?

Even with vendors who allow or provide cluster tools, I don’t use an automated autocluster tool at this point. Autocluster tools often omit your closest matches because your closest matches would be in nearly half of all your clusters, which isn’t exactly informative. However, for this purpose, those are the very matches we need to evaluate.

After identifying groups of people that represent the missing grandparent, using our spreadsheet methodology, autoclusters could be useful to identify common surnames and even to compare the trees of our matches using AutoTree, AutoPedigree and AutoKinship. AutoClusters cannot be utilized at Ancestry, but is available through MyHeritage and at GEDmatch, or through Genetic Affairs for 23andMe and FamilyTreeDNA.

Next, let’s move to FamilyTreeDNA.

FamilyTreeDNA

FamilyTreeDNA is the only vendor that provides Family Matching, also known as “bucketing.” FamilyTreeDNA assigns your matches to either a paternal or maternal bucket, or both, based on triangulated matches with someone you’ve linked to a profile in your tree.

The key to Family Matching is to link known Family Finder matches to their profile cards in your tree.

Clicking on the Family Tree link at the top of your personal page allows you to link your matches to the profile cards of your matches.

FamilyTreeDNA utilizes these linked matches to assign those people, and matches who match you and those people, both, on at least one common segment, to the maternal or paternal tabs on your match list.

Always link as many known people as possible (red stars) which will result in more matches being bucketed and assigned to parents’ sides for you, even if neither parent is available to test.

I wrote about Triangulation in Action at FamilyTreeDNA, here.

You can see at the top of my match list that I have a total of 8000 matches of which 3422 are paternal, 1517 are maternal and 3 match on both sides. Full siblings, their (and my) children and their descendants will always match on both sides. People with endogamy across both parents may have several matches on both sides.

If your relevant parent has tested, always work from their test.

Because we are searching for the maternal grandfather, in this case, we can ignore all tests that are bucketed as paternal matches.

Given that we are searching for my maternal grandfather, I probably have not been able to link as many maternal matches, other than possibly ones from my maternal grandmother. This means that the maternal grandfather’s matches are not bucketed because there are no identified matches to link on that side of my tree.

If you sort by maternal and paternal tabs, you’ll miss people who aren’t bucketed, meaning they have no maternal or paternal icon, so I recommend simply scanning down the list and processing maternal matches and non-bucketed matches.

By being able to confidently ignore paternally bucketed matches and only processing maternal and non-assigned matches, this is equivalent to processing the first 48 total matches. If I were to only look at the first 15 matches, 12 were paternal and only 3 are maternal.

Using bucketing at FamilyTreeDNA is very efficient and saves a lot of work.

Omitting paternal matches also means we are including smaller matches which could potentially be from common ancestors further back in the tree. Or, they could be younger testers. Or simply smaller by the randomness of recombination.

FamilyTreeDNA is a goldmine, with 16 of 20 maternal matches being from the unknown maternal grandfather.

Next, let’s see what’s waiting at MyHeritage.

MyHeritage

MyHeritage is particularly useful if your lineage happens to be from Europe. Of course, if you’re searching for an unknown person, you probably have no idea where they or their ancestors are from. Two of my best matches first appeared at MyHeritage.

Of course, your matches with people who descend from your unknown maternal grandfather won’t have any Theories of Family Relativity, as that tool is based on BOTH a DNA match plus a tree or document match. However, Theories is wonderful to group your matches to your other three grandparents.

MyHeritage provides a great deal of information for each match, including common surnames with your tree. If you recognize the surnames (and shared matches) as paternal or maternal, then you can assign the match. However, the matches you’re most interested in are the highest matches without any surnames in common with you – which likely point to the missing maternal grandfather.

However, those people may, and probably do, have surnames in common with each other.

Of the matches who aren’t attributed to the other three grandparents, the name Ferverda arises again and again. So does Miller, which suggests the grandparent or great-grandparent couple may well be Ferverda/Miller.

Let’s continue working through the process with our spreadsheet and see what we can discover about those surnames.

Our 60 Results

Of the 60 total results, 15 from each vendor, a total of 24 cannot be assigned to other columns through bucketing or shared matches, so are associated with the maternal grandfather. Of course, Michael who descends from both of my maternal grandparents won’t be helpful initially.

Cheryl, Donald and Michael are duplicates at different vendors, but the rest are not.

Of the relevant matches, the majority, 12 are from FamilyTreeDNA, four each are from Ancestry and MyHeritage, and three are from 23andMe.

Of the names provided in the surname fields of matches, in matches’ trees in the first few generations, and the testers’ surnames, Ferverda is repeated 12 times, for 50% of the time. Miller is repeated 9 times, so it’s likely that either of those are the missing grandfather’s surname. Of course, if we had Y-DNA, we’d know the answer to that immediately.

Comparing trees of my matches, we find John Ferverda as the common ancestor between two different matches. John is the son of Hiram Ferverda and Eva Miller who are found in several trees.

That’s a great hint. But is this the breakthrough I need?

What’s Next?

The next step is to look for connections between the maternal grandmother, Edith Lore, who is known in our example, and a Ferverda male. He is probably one of the sons of Hiram Ferverda and Eva Miller. Do they lived in the same area? In close proximity? Do they attend the same church or school? Are they neighbors or live close to the family or some of their relatives? Does she have connections with Ferverda family members? We are narrowing in.

Some of Hiram and Eva’s sons might be able to be eliminated based on age or other factors, or at least be less likely candidates. Any of their children who had moved out of state when the child was conceived would be less likely candidates. Age would be a factor, as would opportunity.

Target testing of the Ferverda sons’ children, or the descendants of their children would (probably) be able to pinpoint which of their sons is more closely related to me (or my mother) than the rest.

In our case, indeed, John Ferverda is the son we are searching for and his descendant, Michael is the highest match on the list. Cheryl and Donald descend from John’s brother, which eliminates him as a candidate. Another tester descends from a third Ferverda son, which eliminates that son as well.

Michael, my actual first cousin with a 755 cM match at one vendor, and 822 cM at a second vendor, is shown by the MyHeritage cM Explainer with an 88% probability that he is my first cousin.

However, when I’m trying to identify the maternal grandfather, which is half of that couple, I need to focus one generation further back in time to eliminate other candidates.

The second and third closest matches are both Donald at 395 cM and Cheryl at 467 cM who also share the same Ferverda/Miller lineage and are the children of my maternal grandfather’s brother.

On the spreadsheet, I need to look at the trees of people who have both Ferverda and Miller, which brought me to both Cheryl and Donald, then Michael, which allowed me to identify John Ferverda, unquestionably, as my grandfather based on the cM match amounts.

Cheryl and Donald, who are confirmed full siblings, and my mother either have to be first cousins, or half siblings. Their match with mother is NOT in the half-sibling range for one sibling, and on the lower edge with the other. Mother also matches Michael as a nephew, not more distantly as she would if he were a first cousin once removed (1C1R) instead of a nephew.

Evaluating these matches combined confirms that my maternal grandfather is indeed John Ferverda.

What About X DNA?

The X chromosome has a unique inheritance path which is sometimes helpful in this circumstance, especially to males.

Women inherit an X chromosome from both parents, but males inherit an X chromosome from ONLY their mother. A male inherits a Y chromosome from his father which is what makes him male. Women inherit two X chromosomes, one from each parent, and no Y, which is what makes them female.

Therefore, if you are a male and are struggling with which side of your tree matches are associated with, the X chromosome may be of help.

Your mother passed her X chromosome to you, which could be:

  • Her entire maternal X, meaning your maternal grandmother’s X chromosome
  • Her entire paternal X, meaning your maternal grandfather’s X chromosome (which descends from his mother)
  • Some combination of your maternal grandmother and maternal grandfather’s chromosomes

One thing we know positively is that a male’s X matches are ALWAYS from their maternal side only, so that should help when dividing a male’s matches maternally or paternally. Note – be aware of potential pedigree collapse, endogamy and identical-by-chance matches if it looks like a male has a X match on his father’s side.

Unfortunately, the X chromosome cannot assist females in the same way, because females inherit an X from both parents. Therefore, they can match people in the same was as a male, but also in additional ways.

  • Females will match their paternal grandmother on her entire X chromosome, and will match one or both of their maternal grandparents on the X chromosome.
  • Females will NEVER match their paternal grandfather’s X chromosome because their father did not inherit an X chromosome from his father.
  • Males will match one or both of their maternal grandparents on their X chromosome.
  • Males will NEVER match their paternal grandparents, because males do not receive an X chromosome from their father.

The usefulness of X DNA matching depends on the inheritance path of both the tester AND their match.

When Can Y-DNA or Mitochondrial DNA Help with Grandparent Identification?

If you recall, I selected the maternal grandfather as the person to seek because no tester carries either the Y-DNA or mitochondrial DNA of their maternal grandfather. In other words, this was the most difficult identification, meaning that any of the other three grandparents would be, or at least could be, easier with the benefit of Y-DNA and/or mitochondrial DNA testing.

In addition to matching, both Y-DNA and mitochondrial DNA will provide testers with location origins, both continental and often much more specific locations based on where other testers and matches are from.

Y-DNA often provides a surname.

Let’s see how these tests, matches and results can assist us.

  • Paternal grandfather – If I was a male descended from John Ferverda paternally, I could have tested both my autosomal DNA PLUS my Y-DNA, which would have immediately revealed the Ferverda surname via Y-DNA. Two Ferverda men are shown in the Ferverda surname DNA project, above.

That revelation would have confirmed the Ferverda surname when combined with the high frequency of Ferverda found among autosomal matches on the spreadsheet.

  • Maternal grandmother – If we were searching for a maternal grandmother, both the male and female sibling testers (as shown in the pedigree chart) would have her mitochondrial DNA which could provide matches to relevant descendants. Mitochondrial DNA at both FamilyTreeDNA and 23andMe could also eliminate anyone who does not match on a common haplogroup, when comparing 23andMe results to 23andMe results, and FamilyTreeDNA to FamilyTreeDNA results at the same level.

At 23andMe, only base level haplogroups are provided, but they are enough to rule out a direct matrilineal line ancestor.

At FamilyTreeDNA, the earlier HVR1 and HVR2 tests provide base level haplogroups, while full sequence testing provides granular, specific haplogroups. Full sequence is the recommended testing level.

  • Paternal grandmother – If we were searching for a paternal grandmother, testers would, of course, need either their father to test his mitochondrial DNA, or for one of his siblings to test which could be used in the same way as described for maternal grandmother matching.

Summary

Successfully identifying a grandparent is dependent on many factors. Before you make that identification, it’s very difficult to know which are more or less important.

For example, if the grandparent is from a part of the world with few testers, you will have far fewer matches, potentially, than other lines from more highly tested regions. In my case, two of my four grandparents’ families, including Ferverda, immigrated in the 1850s, so they had fewer matches than families that have been producing large families in the US for generations.

Endogamy may be a factor.

Family size in past and current generations may be a factor.

Simple luck may be a factor.

Therefore, it’s always wise to test your DNA, and that of your parents and close relatives if possible, and upload to all of the autosomal databases. Then construct an analysis plan based on:

  • How you descend from the grandparent in question, meaning do you carry their X DNA, Y-DNA or mitochondrial DNA.
  • Who else is available to test their autosomal DNA to assist with shared matches and the process of elimination.
  • Who else is available to test for Y-DNA and/or mitochondrial DNA of the ancestor in question.

If you don’t find the answer initially, schedule a revisit of your matches periodically and update your spreadsheet. Sometimes DNA and genealogy is a waiting same.

Just remember, luck always favors the prepared!

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 23rd 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.

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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).
  5. 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 4th 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?
