FamilyTreeDNA Provides Y DNA Haplogroups from Family Finder Autosomal Tests

Big News! FamilyTreeDNA is delivering holiday gifts early!

Y DNA haplogroups are beginning to be delivered as a free benefit to men who took the Family Finder test at FamilyTreeDNA. This is the first wave of a staggered rollout. Haplogroup results will be delivered to several thousand people at a time, in batches, beginning today.

This is no trivial gift and includes LOTS of information that can be used in various ways for your genealogy. Please feel free to share this article. The new Family Finder haplogroups are another reason to take a Family Finder test and to encourage other family members to do so as well.

How is this Even Possible?

Clearly, Y DNA is not autosomal DNA, so how is it possible to obtain a Y DNA or mitochondrial DNA haplogroup from an autosomal test? Great question!

Many autosomal DNA processing chips include a limited number of targeted Y and mitochondrial DNA SNP locations. Generally, those locations are haplogroup predictive, which is how haplogroup information can be obtained from an autosomal DNA test.

Compared to the actual Y DNA and mitochondrial DNA tests, only a small fraction of the information is available through autosomal tests. Only the full sequence mitochondrial DNA test or the Big Y-700 test will provide you with the full story, including your most refined haplogroup, additional information, and matching with other customers.

Having said that, haplogroups obtained from Family Finder provide important clues and genealogical information that will hopefully whet recipients’ appetites for learning even more.

Delivery Schedule

This first group of men to receive haplogroup results consists of testers who have purchased the Family Finder test since March 2019 when the most recent chip was put into production.

FamilyTreeDNA will be rolling haplogroups out in batches of a few thousand each day until everyone’s is complete, in the following order:

  • Family Finder tests purchased since March 2019 (their V3 chip)
  • Family Finder tests purchased between the fall of 2015 to March 2019 (their V2 chip)
  • Family Finder tests purchased from 2010 to the fall of 2015 (their V1 chip)
  • Autosomal uploads from other vendors for customers who have unlocked the advanced Family Finder features for $19

Uploaded DNA Files from Other Vendors

After the results are available for all males who have tested at FamilyTreeDNA, haplogroups will begin to be rolled out to customers who uploaded autosomal DNA files from other companies, meaning MyHeritage, Vitagene, 23andMe, and Ancestry.

To receive haplogroups for files uploaded from other vendors, the Family Finder advanced tool unlock must have been (or can be) purchased for $19. In addition to haplogroups, the unlock also provides access to the chromosome browser, myOrigins (ethnicity), Chromosome painting for myOrigins ethnicity, and ancient Origins.

Both MyHeritage and Vitagene tests are performed in the Gene by Gene lab. Those “uploads” are actually a secure business-to-business transaction, so the file integrity is assured.

Ancestry and 23andMe DNA files are downloaded from those companies, then uploaded to FamilyTreeDNA. Some people build “composite” files in the format of these companies, so FamilyTreeDNA has no way to assure that the original DNA upload file hasn’t been modified and it is a legitimate, unmodified, file from either 23andMe or Ancestry. Hence, in some situations, they are treated differently.

Both Ancestry and 23andMe utilize different chips than FamilyTreeDNA, covering different SNPs. Those results may vary slightly from results available from native FamilyTreeDNA tests, and will also vary from each other. In other words, there’s no consistency, and therefore haplogroup accuracy cannot be confirmed.

Haplogroups resulting from tests performed in the FamilyTreeDNA lab will be visible to matches and on the SNP pages within projects. They will also be used in both Discover and the haplotree statistics. This includes Family Finder plus MyHeritage and Vitagene DNA file uploads.

Tests performed elsewhere will receive haplogroups that will only be visible to the user, or a group administrator viewing a kit within a project. They will not be visible to matches, used in trees or for statistics.

At their recent conference, FamilyTreeDNA provided this slide during an update about what to expect from Family Finder haplogroups.

Today, only Y DNA haplogroups are being provided, but after the new mitochondrial tree is available, customer haplogroups are updated, and MitoDiscover (my name, not theirs) is released, FamilyTreeDNA is planning to provide mitochondrial DNA haplogroups for Family Finder customers as well. The current haplogroup estimate is late 2024 or even into 2025.

Unfortunately, some of Ancestry’s DNA files don’t include mitochondrial DNA SNPs, so some customers who’ve uploaded Ancestry files won’t receive mitochondrial haplogroups.

STR Haplogroups to be Updated

All FamilyTreeDNA customers who have taken Y DNA STR tests, meaning 12, 25, 37, 67, or 111 markers, receive predicted haplogroups. Often, the Family Finder extracted results can provide a more refined haplogroup.

When that is possible, STR test predicted haplogroup results will be updated to the more refined Family Finder haplogroup.

Furthermore, while STR results are quite reliably predicted, Family Finder results are SNP-confirmed.

Notification

When your Family Finder test has received a haplogroup or your STR-derived haplogroup has been updated, you’ll receive an email notification with a link to a short, less than 2-minute video explaining what you’re receiving.

You can also expect emails in the following days with links to additional short videos. If you’d like to watch the videos now, click here.

You can also check your results, of course. If you should have received an email and didn’t, check your spam folder, and if it’s not there, notify FamilyTreeDNA in case your email has managed to get on the bounce list.

Group project administrators will receive notifications when a haplogroup is updated for a member in a project that they manage. This doesn’t just apply to Family Finder haplogroup updates for STR results – notifications will arrive when Big Y haplogroups are updated, too.

Emails about haplogroup updates will include both the old and the updated haplogroup.

Haplogroups may change as other testers receive results, forming a new haplogroup. The Big Y-700 test is evergreen, meaning as the Y tree grows, testers’ results are updated on an ongoing basis.

New View

Let’s take a look at what customers will receive.

In one of my surname projects, one male has taken a Family Finder test, but not the Y DNA test.

Several other men in that same paternal line, who are clearly related (including his brother), have taken Y DNA tests – both STR and the Big Y-700.

We have men who have taken the Big Y-700 test, STR tests only (no Big Y), and one with only a Family Finder test, so let’s compare all three, beginning with the man who has taken a Family Finder test but no Y DNA tests.

He has now been assigned to haplogroup I-BY1031, thanks to his Family Finder test.

Before today, because he has not taken a Y DNA test, he had no haplogroup or Y DNA Results section on his personal page.

Today, he does. Of course, he doesn’t have STR results or matches, but he DOES have confirmed SNP results, at least part way down the tree.

He can view these results on the Haplotree & SNPs tab or in Discover. Let’s look at both.

Haplotree & SNPs

By clicking on the Haplotree & SNPs link, you can view the results by variants (mutations,) as shown below, or by countries, surnames, or recommended projects for each haplogroup.

Of course, as more Family Finder results are rolled out, the more names and countries will appear on the Haplotree.

Recommended Projects

It’s easy to determine which haplogroup projects would be a good fit for people with these new haplogroups to join.

Just view by Recommended Projects, then scan up that column above the selected haplogroup. You can even just click right there to join. It’s that easy!

Results still won’t show on the public project page, because these testers don’t have STR results to display. Perhaps this will encourage additional testing in order to match with other men.

Download SNP Results

If you’re interested, you can download your SNP results in spreadsheet format.

I’m only showing four of my cousin’s positive SNPs, but FamilyTreeDNA was able to extract 358 positive SNPs to assign him to haplogroup I-BY1031.

Are Family Finder Haplogroups Better Than STR Test Predicted Haplogroups?

How do Family Finder haplogroups stack up against STR-predicted haplogroups?

Viewing the Y DNA results of related cousins who have taken STR tests, but not the Big Y-700, we see that their Y DNA haplogroup was predicted as I-M253.

We also know that the haplogroup determined by the Big Y-700 for this line is I-BY73911.

How can we use this information beneficially, and what does it mean?

Discover

Family Finder haplogroups can access Discover, which I wrote about, here.

Clicking on the Discover link takes you to your haplogroup story.

Let’s look at the new Family Finder Haplogroup Story for this tester.

Haplogroup I-BY1031 is about 3100 years old and is found in England, Sweden, the US, and 14 other countries. Of course, as more Family Finder haplogroups are provided to customers, this information will change for many haplogroups, so check back often.

Of course, you’ll want to review every single tab, which are chapters in your ancestral story! The Time Tree shows your haplogroup age in perspective to other haplogroups and their formation, and Ancient Connections anchors haplogroups through archaeology.

You can share any Discover page in several ways. This is a good opportunity to excite other family members about the discoveries revealed through DNA testing and genealogy. Prices are reduced right now with the Holiday Sale, too, so it’s a great time to gift someone else or yourself.

Compare – How Good is Good?

Ok, so how much better is the Family Finder haplogroup than the STR-predicted haplogroup, and how much better is the Big Y-700 haplogroup than the other two?

I’ll use the Discover “Compare” feature to answer these questions.

First, let’s compare the STR-predicted haplogroup of I-M253 to the Family Finder haplogroup of I-BY1031.

I clicked on Compare and entered the haplogroup I wish to compare to I-BY1031.

I-M253 I-BY1031 I-BY73199
Haplogroup Source STR Predicted Family Finder Big Y-700
Formation Year 2600 BCE 1100 BCE 1750 CE
Age – Years ago 4600 3100 270
Era Stone Age, Metal Age Metal Age Modern
Ancestral Locations England, Sweden, Germany, UK, +100 Sweden, England, US, +14 Netherlands
Tested Descendants 26,572 121 2
Branches 6779 69 0 – this is the pot-of-gold end leaf on the branch today

I created this chart to compare the major features of all three haplogroups.

The STR-predicted haplogroup, I-M253, takes you to about 2,600 BCE, or about 4,600 years ago. The Family Finder haplogroup shifts that significantly to about 1100 BCE, or 3100 years ago, so it’s about 1500 years more recent. However, the Big Y haplogroup takes you home – from 3100 years ago to about 270 years ago.

Notice that there’s a LOT of room for refinement under haplogroup I-M253. A Big Y tester might wind up on any of those 6779 branches, and might well be assigned to a newly formed branch with his test. The Family Finder haplogroup, I-BY1031, which was, by the way, discovered through Big Y testing, moved the autosomal test taker forward 1500 years where there are 121 descendants in 69 branches. The Big Y-700 test is the most refined possible, moving you directly into a genealogically relevant timeframe with a very specific location.

I-M253 is found in over 100 countries, I-BY1031 in 17 and I-BY73199 is found only in one – the Netherlands.

Based on confirmed genealogy, the common ancestor of the two men who have Big Y-700 haplogroup I-BY73199 was a man named Hendrik Jans Ferwerda, born in 1806 in the Netherlands, so 217 years ago. Of course, that haplogroup itself could have been born a generation or two before Hendrik. We simply won’t know for sure until more men test. More testers refine the haplotree, haplogroup ages, and refine our genealogy as well.

Haplogroup Comparison and Analysis

Let’s look at the Discover “Compare” feature of the three haplogroups from my family line from the Netherlands. Please note that your results will differ because every haplogroup is different, but this is a good way to compare the three types of haplogroup results and an excellent avenue to illustrate why testing and upgrades are so important.

The haplogroup ages are according to the Discover Time Tree.

FT230048
BY65928
BY61100
I-BY73199 lived about 270 years ago

 All of the base haplogroups in the first column leading to Haplogroup I span the longest elapsed time, about 230,000 years, from Y-Adam to I-M253, the STR-predicted haplogroup, but are the least relevant to contemporary genealogy. They do tell us where we came from more distantly.

The second column moves you about 1500 years forward in time to the Family Finder confirmed haplogroup, reducing the location from pretty much everyplace in Europe (plus a few more locations) with more than 6700 branches, to 69 branches in only 17 countries.

With the fewest haplogroups, the third column spans the most recent 2800 years, bringing you unquestionably into the genealogically relevant timeframe, 270 years ago, in only one country where surnames apply.

If we had more testers from the Netherlands or nearby regions, there would probably be more branches on the tree between BY1031 and BY73199, the Big Y-700 haplogroup.

The second column is clearly an improvement over the first column which gets us to I-M253. The Family Finder upgrade from I-M253 to BY1031 provides information about our ancestors 3000-4500 years ago, where they lived and culturally, what they were doing. Ancient Connections enhance that understanding.

But the third column moves into the modern area where surnames are relevant and is the holy grail of genealogy. It’s a journey to get from Adam to the Netherlands in one family 270 years ago, but we can do it successfully between Family Finder and the Big Y-700.

Family Finder Matching

Given that these new haplogroups result from Family Finder, how do these results show in Family Finder matching? How do we know if someone with a haplogroup has taken a Y DNA test or if their haplogroup is from their Family Finder test?

  • All Family Finder haplogroups will show in the results for people who tested at FamilyTreeDNA as soon as they are all rolled out
  • All MyHeritage and Vitagene uploads, because they are processed by the Gene by Gene lab, will be shown IF they have purchased the unlock.
  • No Ancestry or 23andMe haplogroups will be shown to Family Finder matches

To determine whether or not your matches’ haplogroups result from a Y DNA test or a Family Finder haplogroup, on your Family Finder match page, look just beneath the name of your matches.

The first man above received the Family Finder haplogroup. You can see he has no other tests listed. The second man has taken the Big Y-700 test. You can see that he has a different haplogroup, and if you look beneath his name, you’ll see that he took the Big Y-700 test.

For other men, you may see the 67 or 111 marker tests, for example, so you’ll know that they are available for Y-DNA matching. That may be important information because you can then visit the appropriate surname project to see if they happen to be listed with an earliest known ancestor.

After the rollout is complete, If you have a male Family Finder match with no haplogroup shown, you know that:

  • They did not test at FamilyTree DNA
  • If they uploaded from MyHeritage or Vitagene, they did not unlock the advanced Family Finder features
  • Or, they tested at either 23andMe or Ancestry, and uploaded their results

You can always reach out to your match and ask.

How to Use This Information

There are several great ways to utilize this new information.

I have a roadblock with my Moore line. Moore is a common surname with many, many origins, so I have autosomal matches to several Moore individuals who may or may not be from my Moore line.

I do know the base haplogroup of my Moore men, but I do not have a Big Y, unfortunately, and can’t upgrade because the tester is deceased. (I wish I had ordered the Big Y out the gate, but too late now.)

As soon as the results are complete for all of the testers, I’ll be able, by process of elimination to some extent, focus ONLY on the testers who fall into Family Finder haplogroup of my Moore cousins, or at least haplogroup close for Ancestry or 23andMe upload customers. In other words, I can eliminate the rest.

I can then ask the men with a similar haplogroup to my proven Moore cousins for more information, including whether they would be willing to take a Y DNA test.

  • Second, as soon as the Family Finder processing is complete, I will know that all male Family Finder matches and uploads from MyHeritage and Vitagene that have paid for the unlock will have haplogroups displayed on the Family Finder Match page. Therefore, if there’s a male Moore with no haplogroup, I can reach out to see where they tested and if a haplogroup has been assigned, even if it’s from Ancestry or 23andMe and isn’t displayed in Family Finder.

If so, and they share the haplogroup with me, I’ll be able to include or exclude them. If included, I can then ask if they would consider taking a Y DNA test.

  • Third, for lines I don’t yet have Y DNA testers for, I can now peruse my matches, and my cousins’ matches for that line. See items one and two, above. Even if they don’t reply or agree to Y DNA testing, at least now I have SOME haplogroup for that missing line.

Discover will help me flesh out the information I have, narrow regions, find projects, look at ancient DNA for hints, and more.

  • Fourth, the haplogroups themselves. I don’t know how many million tests FamilyTreeDNA has in their database, but if we assume that half of those are male, some percentage won’t have taken a Y DNA test at all. We’ll be able to obtain Y-DNA information for lines where there may be no other living descendant. I have at least one like that. He was the end of the surname line and is deceased, with no sons.

I’m literally ecstatic that I’ll be able to obtain at least something for that line. If it’s anything like my example Netherlands lineage, the Family Finder haplogroup may be able to point me to an important region of Europe – or maybe someplace else very unexpected.

The Bottom Line

Here’s the bottom line. You don’t know what you don’t know – and our ancestors are FULL of surprises.

I can’t even begin to tell you how MUCH I’m looking forward to this haplogroup rollout.

To prepare, I’m making a list of my genealogical lines:

  • If the paternal line, meaning surname line, is represented by any match in any database
  • If that line is represented by a known person in the FamilyTreeDNA database and by whom
  • If they or someone from that line has joined a surname or other FamilyTreeDNA project, and if so, which one
  • If they’ve taken a Y DNA test, and what kind – watch STR results for an updated haplogroup
  • If they’ve taken a Family Finder test – my cousin is a good example of a known individual whose kit I can watch for a new haplogroup
  • Old and new haplogroup, if applicable

If my only relative from that line is in another vendor’s database, I’ll ask if they will upload their file to FamilyTreeDNA – and explain why by sharing this article. (Feel free to do the same.) A Y DNA haplogroup is a good incentive, and I would be glad to pay for the unlock at FamilyTreeDNA for cousins who represent Y and mitochondrial DNA lines I don’t already have.

One way I sweeten the pie is to offer testing scholarships to select lines where I need either the Y DNA or mitochondrial DNA of relevant ancestors. It’s a good thing these haplogroups are being rolled out a few thousand at a time! I need to budget for all the scholarships I’ll want to offer.

I feel like I won the lottery, and FamilyTreeDNA is giving me a free haplogroup encyclopedia of information about my ancestors through my cousins – even those who haven’t taken Y DNA tests. I can’t even express how happy this makes me.

What lines do you want to discover more about, and what is your plan? Tests are on sale now if you need them!

Michel de Forest (c1638–c1690): Acadian Family Founder – 52 Ancestors #411

There are some things we know about Michel (de) Forest, and a lot that we don’t. Furthermore, there are myths that, with repeated telling, have become widely accepted and ingrained into genealogy, but now seem to have been disproven. Thankfully, the lives of our ancestors continue to come into clearer focus.

Let’s start with the facts we have, beginning with the trusty census records.

Acadian Censuses

The French Acadians settled in what is now Nova Scotia beginning in 1632, moving to Port Royal in 1635 on the Bay of Fundy.

It’s estimated that by 1653, there were 45-50 households in Port Royal and about 60 single men. Of course, those men would have been very interested in finding wives.

A prisoner in 1654 estimated that there were about 270 residents.

From about 1653 to 1667, Acadia was under English rule, not French. This is actually important for Michel de Forest’s history, because as a French man, he would probably have arrived prior to 1653. We know he was married in 1666, so he would already have been in Acadia before 1667.

The Acadians took periodic censuses beginning in 1671. While there are millions of Acadian descendants today, the founding population was small. Given the challenges they faced, it’s actually amazing that they survived at all and that their descendants thrived, even after the Acadian Removal, known as Le Grande Derangement.

The first record we find for Michel de Forest is the 1671 census in Port Royal, Acadia, transcribed here by Lucie LeBlanc Consentino, where he is listed as Michel de Forest, age 33, wife Marie Hebert, 20, with children Michel 4, Pierre 2, René 1, 12 cattle and two sheep.

This tells us that he has been in Acadia for at least five years, in order to have married and have a 4-year-old child. He would have been about 27 when he married.

This also provides a birth year for him of about 1638.

The next census, taken in 1678, shows Michel as a widower with 4 acres, 3 cows, 2 calves, 1 gun, four boys, ages 12, 10, 8, and 3, plus two girls, ages 6 and 4. His age is not given.

Assuming that all of Michel’s children were born to the same mother, this suggests that Marie Hebert died sometime in or after 1675, when the last child would have been born.

Marie and Michel were only married for between 9 and 12 years. I wonder if she died about 1677 in childbirth. Of course, there’s no evidence for that. If she died giving birth to that child, or shortly thereafter, the child is deceased too.

In 1684, a new governor was appointed to Acadia who described the Acadians as living simply and pastorally. He claimed they lived better than Canadians, never lacking meat or bread, but weren’t as industrious. He said they never put anything away for a bad year, and their dowries were small – a few francs and a cow in calf, a ewe, and a sow.

Maybe that explains at least one of Michel’s cows and sheep in 1671.

In 1686, Michel is once again enumerated in the census, age 47, now married to Jacqueline Benoit whose age is given as 13, but is very likely erroneously recorded. Census takers then were probably much the same as census takers decades later in the US. However, accuracy was probably not deemed to be as important in Acadia. After all, everyone knew everyone else. The entire census consisted of 392 people, but scholars estimate that it was probably closer to 500.

Based on Jacqueline’s earlier family records, I believe she was 17. Michel’s children with Marie Hebert are listed as Michel 19, Pierre 18, René 16, Gabriel 13, Marie 11, and Jean-Baptiste 9. Michel had one gun, 8 sheep, and 4 hogs and was cultivating 5 arpents of land.

Age 47 puts Michel’s birth year at 1639. He was either newly married, or his wife was pregnant, because their only child was born about 1687.

In 1686, Jean-Baptiste, at age 9, fits the same pattern as the child who was 3 in 1678, but the math is slightly off. Age 9 in 1686 would put Jean-Baptiste’s birth year in 1677. Perhaps 1676 is the actual birth year, which puts Marie Hebert’s death sometime between 1676 and the 1678 census.

A 1688 report from the governor states that there was a labor shortage, a shortage of manure necessary for developing the uplands and also a shortage of tidelands that would be easy to dyke. As a result, 25-30 (mostly) younger people had moved to Minas in the last 6 years.

By sometime in 1691, Michel’s second wife, Jacqueline Benoit had remarried to Guillaume Trahan. In the 1693 census, she was listed with him as age 20. Michel Forest’s daughter Marguerite, age 6, is shown with the family, but without a surname, as is Angelique, age 1. Angelique would have been born to Jacqueline and Guillaume.

In May of 1690, Michel’s son, René signed the required loyalty oath, but Michel did not, which tells us that he had died by then.

Therefore, we know that Michel died sometime between the birth of his last child, Marguerite, born about 1687 to his second wife, Jacqueline, and May of 1690.

Michel’s youngest child, Marguerite, married about 1705 to Etienne Comeau and had nine children. She is shown with her mother and step-father in 1693 in Les Mines.

Acadia Land Location

Based on later records and a reconstruction of the 1707 census which includes Michel’s son, René de Forest, we know the probable location of Michel’s land. Further confirming this, Karen Theriot Reader reports that Michel had obtained a considerable concession extending over a mile in depth, a dozen miles to the east of the fort in Port Royal.

The René Forest Village is a dozen miles east of the fort, exactly where we would expect based on the description of that concession. A mile in depth is a LOT of land, which would have begun with water frontage on the rivière Dauphin, now the Annapolis River.

Based on the legend, a mile in depth would extend across 201 and possibly to or across 101, Harvest Highway, as well.

As further evidence, Michel married Marie Hebert, daughter of Etienne Hebert and Marie Gaudet, who lived on the adjacent farm.

The Hebert’s lived in close proximity to the de Forest family, maybe half a mile away, which would make courting easy! MapAnnapolis was kind enough to map these locations, here.

The Nova Scotia Archives shows the Hebert and Forest villages on this 1733 map.

This land remained in those families for a century. It’s no wonder that these families intermarried heavily.

Spousal Candidates

There weren’t many marriageable-age young women to choose from among Acadian families, which explains why some men chose Native wives.

I did some analysis on the 1671 census, which proved quite interesting.

There were a total of 68 families in Port Royal in 1671. With that small number of families, it’s no wonder everyone is related to everyone else within just a few generations. The descendant population is highly endogamous today. WikiTree reports that Michel has more than 28,000 identified descendants.

The 1671 census is unique in that families with older children noted how many married children they had. Then, the married child was also enumerated with their own family.

For example, Marie Hebert’s mother was widowed, and her census entry reads thus:

“Marie Gaudet, widow of Etienne Hebert, 38. She has 10 children, two married children: Marie 20, Marguerite 19, Emmanuel 18, not yet married”…and so forth

Then, Marie Hebert is listed with her husband, Michel de Forest, along with their children.

This provides us with a rare opportunity. First, we can match children, particularly females, up with their parents so long as at least one parent is still living.

This dual listing methodology also provides an unexpected glimpse into something else. Missing married children. At least six married children females in the age bracket that I was studying were noted as “married,” but they are not listed with a spouse anyplace. This could be because they had left the area, but that exodus hadn’t really begun that early and wouldn’t for another 15 years or so. It’s also possible that they were simply missed, but that seems unlikely, given that everyone literally knew everyone else and where they lived. Furthermore, everyone lived along the river.

After matching the married daughters up with their husbands, two name-based matches remained questionable, given that the ages were significantly different. For example, one couple lists Marie Gautrot as their married daughter, age 35, but Claude Terriau’s listing shows Marie Gautrot, age 24, as his wife. Their oldest child is 9. This may or may not be the same person.

My goal was to see how many females were of marriage age and single in 1666 when Michel de Forest married. I calculated the probable marriage date for each female based on the oldest child’s age minus one year.

Based on the women living in 1671, 5 females other than Michel’s wife were married in 1666, so they may or may not have been available for marriage when Michel was looking.

I entered all the women between ages 18 and 35 in 1671 into a spreadsheet, meaning they were between 13 and 30 in 1666 when Michel was about 26 or 27. While 13 is extremely young to marry, it appears that young women began marrying at that age. I suspect they married as soon as they reached puberty or shortly thereafter.

After all, finding a “good” husband was important, and in Acadia, pickings were slim. Plus, you really wanted your daughter to settle nearby, so if her “intended” was a neighbor, so much the better. And if her “intended” also had a farm and a cow – that was the veritable jackpot!

The total number of females aged 18-35 in 1671 was only 41, one of which was a widow whose age I can’t reconcile accurately.

Of those people, only 12 were unquestionably unmarried in 1666, plus possibly the widow. If all of the women who married in 1666 were unspoken for in 1666 when Michael was courting, the absolute maximum number of available spouses in that age range was 18, including Michel’s wife. I did not calculate the number of marriage-age males, but there seemed to be more males than females.

Eighteen potential spouses are actually not many to choose from. “Here are 18 people – pick one to marry for the rest of your life.” Today, we hope and expect to be happy. I’d bet they simply hoped not to be miserable and to survive. The most important qualities were probably selecting someone kind and industrious, although young people might not have realized that.

The priests would not sanction marriages to Native women unless the woman would convert and be baptized in the Catholic church, so the men who married Native women tended to live in the woods among the Native people, adopting their lifeways.

The female Acadian marriage age was quite young, ranging from 13-25. The average was 17 years and 10 months.

Calculated marriage ages of women in that age bracket based on the age of the oldest child, less one year, were:

  • 13 years old – 2 people
  • 14 – 3
  • 15 – 5
  • 16 – 2
  • 17 – 5
  • 18 – 2
  • 19 – 6
  • 20 – 3
  • 21 – 1
  • 22 – 1
  • 23 – 1
  • 24 – 1
  • 25 – 1

It’s clear from these numbers that most people were married by 20, and by 21, few female marriage partners were left. The marriages of the women in their 20s could also be erroneous if their first child or children died before the census.

Church records before 1702 do not survive, so we can’t check further.

Michel probably climbed in his birchbark canoe, wearing his cleanest clothes, and paddled the short distance to visit Marie’s parents, asking permission to marry their daughter. Or, perhaps, he asked them in church. They would have seen each other there, at least weekly, so long as the colony had a priest in residence.

Or, maybe Michel became inspired when he was visiting Marie and just popped the question one fine day when she looked particularly beautiful as they strolled through the fields on their adjoining lands.

Because Michel had no parents in the settlement, he would have established himself as a farmer by that point, proving his ability to support a wife and children. This is probably one of the reasons he didn’t marry until he was 28. Regardless of when he arrived, or under what circumstances, he still needed time to build a foundation that would make him marriage-eligible. That would mean being either a farmer, with land, or a tradesman. Something with a dependable income – as dependable as anything could be in a region torn by conflict between the French and English.

If Michel were already farming when he married, which is likely, Marie’s parents would have been excited because their daughter would be living in very close proximity, literally within sight. Or, perhaps, this is how the de Forest family came to establish their home, then the village, next to the Heberts.

Life and Death in Acadia

Michel died young. If he perished in 1687, he would have been roughly 49 years old. If he died in 1690, he would have been 52. Certainly, he could have died of natural causes, but it’s more likely that something else was responsible for his death.

Of course, without modern medical care, any wound could fester and cause sepsis, or an accident with a horse could end a life in the blink of an eye. An appendicitis attack was a death sentence. Dysentery, typhoid, and other diseases of contamination wiped out entire families.

However, none of his children died, nor did his wife at the time, so something else caused Michel’s death.

One likely candidate is the warfare with the English. Acadia had been settled by the French, but the English coveted the land, eventually taking permanent possession, in 1710. However, they had been trying for decades, and control of Acadia has passed back and forth more than once – and never peacefully.

However, 1690 was particularly heinous.

1690

In 1690, Acadia was once again plundered and burned by the English out of Boston. The church in Port Royal and 28 homes were burned, but not the mills and upriver farms, which may have included the Forest homestead.

The French pirate, Pierre Baptiste attempted to defend Port Royal in 1690 but was unsuccessful. A year later, he was successfully recruiting men in Acadia to join him in capturing British ships.

The Acadians in Port Royal swore an oath of allegiance in May of 1690 hoping to de-escalate the situation. Instead, their priest was kidnapped and taken to Boston. Luckily for us, the priest took the loyalty oath document with him, which tells us which males were alive as of May 1690. I transcribed that list, here.

Michel is not on the list, and neither are his two oldest sons, Michel and Pierre. The eldest was probably married already, but Pierre was not. Michel’s third son, René de Forest, signed the oath and stayed in Acadia to work his father’s land. The older two brothers settled shortly thereafter, if they hadn’t already, in Grand Pre which had been founded in 1686 by the Melanson family.

The English were firmly in charge of Acadia after the 1690 attack.

Emboldened, 2 English pirates took advantage of the opportunity and burned more homes, killing people and livestock.

However, by this time, it appears that Michel was already gone. His children and widow would have been left to fight those battles.

Did Michel die defending his home and family in 1690, along with his son or sons? Was their homestead burned either in the initial attack or by the pirates?

Origins

Michel was the first Forest, de Forest or Foret settler in Acadia – the founder of the Acadian Forest family. He was clearly there before he married in either 1665 or 1666, based on the age of his eldest child.

If Michel was born about 1638 or 1639, he would have been roughly 28 years old when he married.

Forest family researchers are fortunate to have long-time researcher, John P. DeLong, as a family member. John is a descendant and has been studying this family for more than 35 years. He’s been providing his web page for more than a quarter century. Thank you, John!!

John has evaluated the various famous and infamous stories about Michel’s origins, piece by piece, including both a mysterious name and religious denominational change – all of which are without any scrap of evidence other than uncertain oral history. Sometimes facts are morphed or molded a bit to fit the narrative – and that seems to be what happened over the decades, and indeed, centuries, regarding Michel.

There are two long-standing myths, meaning oral history, surrounding Michel de Forest. John goes into great detail, documenting both exceedingly well on his site, “The Origins of the Acadian Michel Forest.”

I’m not going to repeat them herel, but I strongly encourage all Michel Forest researchers to read his extensive research, points, counterpoints, and citations. It’s an excellent piece of work.

Not only is John’s research exemplary, it’s backed up by Y-DNA evidence. Assuming the tester’s genealogy is accurate, our Michel de Forest is NOT a descendant of the French Huguenot family who sought refuge in the Netherlands. Their Y-DNA, documented in the Forest Y-DNA project, here, is entirely different.

One of the theories involves our immigrant Michel being born by another name in the Netherlands to Huguenot refugees, then changing both his name and religion when immigrating to Acadia.

He was also rumored to be related to the Forest family of New Netherlands, now New York. That family descends from the Dutch Huguenot family.

An older story involved being born to another couple from the same line, but that was debunked earlier.

I concur with John DeLong’s conclusion that Michel very likely arrived around 1650 with Governor d’Aulnay:

Governor d’Aulnay was recruiting young men to voyage to Acadia between 1645 and 1650. Furthermore, a marriage delay of sixteen years is understandable. He (Michel) had to mature to adulthood, perhaps wait for his period of servitude to end, maybe spend some time setting up his own farm to become independent, and then had to wait for an eligible bride to mature given the shortage of marriageable woman in the colony. This could take up sixteen years. Surely, the fact that his second marriage was to a girl of 14 or 15 indicates that there was a serious shortage of eligible women in the colony even as late as 1686.

Without any other evidence, this is the most reasonable hypothesis.

What we know for sure is that Michel arrived in Acadia without any known family. This makes me wonder if Michel was an orphan or perhaps an adventurous teenager who set out to see the world.

Michel must have been wide-eyed as he set eyes on Port Royal for the first time. He would spend the rest of his life here, and his bones would rest in this very location.

Forest DNA

Thank goodness for the Forest DNA Project at FamilyTreeDNA. Y-DNA for males is passed from father to son, unmixed with the DNA of the mother. Occasional small mutations occur, allowing descendants to be grouped into family lines, but overall, Michel’s direct male descendants will match each other. In other words, de Forest or Forest men will match other Forest men.

Several of Michel’s direct patrilineal descendants have tested, and, as expected, they match each other. They do NOT match the Huguenot/New Netherlands group – not even close. Assuming the genealogy of the New Netherlands descendant is accurate, and no undocumented adoptions have occurred, this dispels any remaining doubt that anyone might have.

Often, stories become so ingrained in families and culture that disproof is hard to accept, especially when the story defines part of the family or cultural identity. One might ask themselves – how could these family stories have been so wrong for so long?

In this case, we know that at least two different de Forest descendant lines dating from a common ancestor in about 1830 carried this oral history, independently. Of course, we have NO idea how that story began. Maybe someone “noticed” the similarities in names and assumed that they were connected. Maybe someone told someone else they were connected. Regardless, it happened.

Then, after 150+ years of being repeated, it was accepted as incontrovertible fact, and everyone believed it. Why wouldn’t they? Those stories had been in the family “forever” so they “had” to be true. In the early/mid 1900s, books were published, further cementing the stories into the family psyche. If it’s in print, it has to be accurate, right? Then, online trees began, and what was previously in print in libraries became easily accessible from home, and the age of click/copy/paste began and continues to this day.

Let me say this again – Acadian Michel Forest’s Y-DNA, meaning his direct paternal line, does not match with the paternal line of the Dutch family, meaning that Gereyt de Forest who was born in 1737 to the wealthy Protestant de Forest family in Leiden in the Netherlands was NOT the Catholic Michel de Forest of Acadia. There are no facts that add up, and neither does the Y-DNA.

What do we know about Michel Forest’s DNA results, aside from the fact that his descendants’ Y-DNA doesn’t match the Dutch line of the same or similar surname who settled in New Netherlands?

Several of Michel de Forest’s descendants have tested, which you can see here.

I wish very much that every tester would enter their earliest known ancestor.

The volunteer project administrators have grouped Michel Forest’s known descendants together, above. You’ll notice that their haplogroups are estimated to be R-M269 based on STR tests, or the much more refined haplogroup R-FT146490 based on a Big Y test taken by kit number N36241.

On the other hand, kit number 939910 is reported to be a descendant of Melchoir de Forest III who was born about 1521 and died about 1571 or 1572. This is the Huguenot branch that immigrated to the Netherlands, then to New Netherlands. This is the line rumored to be Michel’s ancestors. Specifically, Gerryt (Geryt, Geryte, Gerryte) de Foreest/Forest born in 1637 was said to have gone to Acadia where he changed his name to Michel and became Catholic again. The birth year aligns approximately, but that’s all. Nothing more is known of Gerryte, so he was the perfect candidate to morph into Michel. A similar birth year, a continent apart, with no additional evidence, does not the same person make.

Assuming the tester’s genealogy is accurate, the Melchior haplogroup is I-FT413656, and the test can be found in the Ungrouped section.

I would very much like to see another confirmed test from any paternally descended male Melchior Forest descendant, preferably through another son. This would confirm the difference.

The base haplogroup of the Acadian Michel de Forest group is haplogroup R and the haplogroup of the Huguenot group is I. This alone disproves this theory, as those haplogroups aren’t related in thousands of years.

There are several testers in the project’s Ungrouped section. I can tell that the project administrators were actively trying to test all lines with a similar surname to see if any match. So far, they don’t.

The Group Time Tree, available under the project menu, shows all of the testers from both groups, together on one tree by time, across the top.

It’s easy to see that Acadian Michel De Forest’s group doesn’t match any other group of men with the same or similar surnames. I love this tool, because you can view all project members who have taken the Big-Y test, together, with time.

Additionally, the Forest Project has provided a summary, here that is a bit outdated, but the essence is still of value. Michel does not descend from Jesse, who descends from Melchior.

Additional information is available exclusively to members of the Forest Association, which can be found here. I’m not a member, so I don’t know what additional information might be there.

Discover More

FamilyTreeDNA has provided the free Discover tool. One of the Forest men has taken the Big Y test and has been assigned the detailed haplogroup of R-FT146490. Haplogroup R-M269 is about 6350 years old, while the mutation responsible for R-FT146490 occurred about 200 years ago.

This fine, granular information, combined with other men who have taken the Big Y test and have either the same or nearby haplogroups, provides us with significant information about our de Forest family.

It confirms who we are and tells us who we’re not.

The Discover tool provides us with information about the age of Michel’s haplogroup, R-FT146490.

The haplogroup of Michel’s direct male paternal-line descendants is estimated to have been born about the year 1800, which suggests that if more descendants of Michel through different sons were to test, we might well identify another haplogroup someplace between 1800 and the parent haplogroup born about 800 CE. That’s a thousand years. Where were our ancestors?

These dates represent ranges, though, so the 1800 date could potentially be earlier.

Perhaps additional Forest men would be willing to upgrade.

Aside from Michel’s descendants upgrading, it would be very useful to see how closely we match other men from France. But that’s a problem.

A huge challenge for Acadian DNA testing is that DNA testing in France is illegal, so most of the French tests we have are from lines that left for the New World or elsewhere.

Perhaps in time, Michel’s origins before Acadia will be revealed. Where were his ancestors between 800 CE and when we find Michel in Acadia by 1666? That’s a BIG gap. We need more of Michel’s descendants to test, preferably at least one person from each son.

Michel Summary

Michael’s life was short, and while we know who he married and the names of his children, thanks to the census, so much has been lost as a result of the destruction of the early Catholic church records.

That Catholic church that was burned by the British in 1690 assuredly held the records we need. However, the Acadians had much more than church registers to worry about after that attack. They had to bury their dead and provide for the living, somehow.

Under normal circumstances, Michael’s funeral would have been held inside the church near the fort in Annapolis Royal, and he would have been laid to rest in the cemetery beside the church. That may or may not be what happened, depending on when and how he died. The original Fort and historic area, including the church location and cemetery, is shown between St. George Street, Prince Albert, and the Bay, above.

The church no longer exists, and Acadian graves are unmarked today, but we know they were buried in what is now called the Garrison Cemetery, overlooking the Bay that welcomed Michel about 40 years earlier.

Haplogroups: DNA SNPs Are Breadcrumbs – Follow Their Path

Recently a reader asked some great questions.

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

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

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

First, a reminder that:

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

Let’s look at how this works.

Autosomal vs Y-DNA Inheritance

Click on image to enlarge

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

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

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

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

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

Y-DNA in the Same Generation

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

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

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

The key word here is “essentially.”

Y-DNA

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

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

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

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

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

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

Y-DNA Testing

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

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

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

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

Estes Male Breadcrumb Trail

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

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

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

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

How do we know that?

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

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

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

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

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

You can see haplogroup R-BY490 boxed in blue.

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

How do we know that?

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

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

How do we know that?

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

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

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

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

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

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

The Discover Reports

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

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

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

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

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

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

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

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

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

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

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

The new Globetrekker tool answers that question.

The Breadcrumb Trail

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

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

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

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

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

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

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

Pretty cool, huh!!

End to End

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

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

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

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

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

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

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

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

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

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

Which DNA Test Should I Buy? And Why?

Which DNA test should I buy, and why?

I receive questions like this often. As a reminder, I don’t take private clients anymore, which means I don’t provide this type of individual consulting or advice. However, I’m doing the next best thing! In this article, I’m sharing the step-by-step process that I utilize to evaluate these questions so you can use the process too.

It’s important to know what questions to ask and how to evaluate each situation to arrive at the best answer for each person.

Here’s the question I received from someone I’ll call John. I’ve modified the wording slightly and changed the names for privacy.

I’m a male, and my mother was born in Charleston, SC. My maternal grandmother’s maiden name was Jones and a paternal surname was Davis. The family was supposed to have been Black, Dutch, Pennsylvania Dutch, and Scots-Irish…only once was I told I was 3/16 Indian, with Davis being 3/4 and Jones being full Indian.

Do I have enough reasonable information to buy a test, and which one?

Please note that it’s common for questions to arrive without all the information you need to provide a sound answer – so it’s up to you to ask those questions and obtain clarification.

Multiple Questions

There are actually multiple questions here, so let me parse this a bit.

  1. John never mentioned what his testing goal was.
  2. He also never exactly said how the paternal line of Davis was connected, so I’ve made an assumption. For educational purposes, it doesn’t matter because we’re going to walk through the evaluation process, which is the same regardless.
  3. John did not include a tree or a link to a tree, so I created a rudimentary tree to sort through this. I need the visuals and normally just sketch it out on paper quickly.
  4. Does John have enough information to purchase a test?
  5. If so, which test?

There is no “one size fits all” answer, so let’s discuss these one by one.

Easy Answers First

The answer to #4 is easy.

Anyone with any amount of information can purchase a DNA test. Adoptees do it all the time, and they have no prior information.

So, yes, John can purchase a test.

The more difficult question is which test, because that answer depends on John’s goals and whether he’s just looking for some quick information or really wants to delve into genealogy and learn. Neither approach is wrong.

Many people think they want a quick answer –  and then quickly figure out that they really want to know much more about their ancestors.

I wrote an article titled DNA Results – First Glances at Ethnicity and Matching for new testers, here.

Goals

Based on what John said, I’m going to presume his goals are probably:

  • To prove or disprove the family oral history of Black, Dutch, Pennsylvania Dutch (which is actually German,) Scots-Irish, and potentially Native American.
  • John didn’t mention actual genealogy, which would include DNA matches and trees, so we will count that as something John is interested in secondarily. However, he may need genealogy records to reach his primary goal.

If you’re thinking, “The process of answering this seemingly easy question is more complex than I thought,” you’d be right.

Ethnicity in General

It sounds like John is interested in ethnicity testing. Lots of people think that “the answer” will be found there – and sometimes they are right. Often not so much. It depends.

The great news is that John really doesn’t need any information at all to take an autosomal DNA test, and it doesn’t matter if the test-taker is male or female.

To calculate each tester’s ethnicity, every testing company compiles their own reference populations, and John will receive different results at each of the major companies. Each company updates their ethnicity results from time to time as well, and they will change.

Additionally, each company provides different tools for their customers.

The ethnicity results at different companies generally won’t match each other exactly, and sometimes the populations look quite different.

Normally, DNA from a specific ancestor can be found for at least 5 or 6 generations. Of course, that means their DNA, along with the DNA from all of your other ancestors is essentially combined in a communal genetic “pot” of your chromosomes, and the DNA testing company needs to sort it out and analyze your DNA for ethnicity.

DNA descended from ancestors, and their populations, further back in people’s trees may not be discerned at all using autosomal DNA tests.

A much more specific “ethnicity” can be obtained for both the Y-DNA line, which is a direct patrilineal line for men (blue arrow,) and the mitochondrial DNA line (pink arrows,) which is a direct matrilineal line for everyone, using those specific tests.

We will discuss both of those tests after we talk about the autosomal tests available from the four major genealogy DNA testing companies. All of these tools can and should be used together.

Let’s Start with Native American

Let’s evaluate the information that John provided.

John was told that he “was 3/16 Indian, with Davis being 3/4 and Jones being full Indian.”

We need to evaluate this part of his question slightly differently.

I discussed this in the article, Ancestral DNA Percentages – How Much of Them is in You?

First, we need to convert generations to 16ths.

You have two ancestors in your parent’s generation, four in your grandparents, and so forth. You have 16 great-great-grandparents. So, if John was 3/16th Native, then three of his great-great-grandparents would have been fully Native, or an equivalent percentage. In other words, six ancestors in that generation could have been half-Native. Based on what John said, they would have come from his mother’s side of the tree. John is fortunate to have that much information to work with.

He told us enough about his tree that we can evaluate the statement that he might be 3/16ths Native.

Here’s the tree I quickly assembled in a spreadsheet based on John’s information.

His father, at left, is not part of the equation based on the information John provided.

On his mother’s side, John said that Grandfather Davis is supposed to be three-quarters Native, which translates to 12/16ths. Please note that it would be extremely beneficial to find a Y-DNA tester from his Davis line, like one of his mother’s brothers, for example.

John said that his Grandmother Jones is supposed to be 100% Native, so 16/16ths.

Added together, those sum to 28/32, which reduces down to 14/16th or 7/8th for John’s mother.

John would have received half of his autosomal DNA from his mother and half from his non-Native father. That means that if John’s father is 100% non-Native, John would be half of 14/16ths or 7/16ths, so just shy of half Native.

Of course, we know that we don’t always receive exactly 50% of each of our ancestors’ DNA (except for our parents,) but we would expect to see something in the ballpark of 40-45% Native for John if his grandmother was 100% Native and his grandfather was 75%.

Using simple logic here, for John’s grandmother to be 100% Native, she would almost assuredly have been a registered tribal member, and the same if his grandfather was 75% Native. I would think that information would be readily available and well-known to the family – so I doubt that this percentage is accurate. It would be easy to check, though, on various census records during their lifetimes where they would likely have been recorded as “Indian.” They might have been in the special “Indian Census” taken and might be living on a reservation.

It should also be relatively easy to find their parents since all family members were listed every ten years in the US beginning with the 1850 census.

The simple answer is that if John’s grandparents had as much Native as reported, he would be more than 3/16th – so both of these factoids cannot simultaneously be accurate. But that does NOT mean neither is accurate.

John could be 7/8th or 40ish%, 3/16th or 18ish%, or some other percentage. Sometimes, where there is smoke, there is fire. And that seems to be the quandary John is seeking to resolve.

Would  Ethnicity/Population Tests Show This Much Native?

Any of the four major testing companies would show Native for someone whose percentage would be in the 40% or 18% ballpark.

The easiest ethnicities to tell apart from one another are continental-level populations. John also stated that he thinks he may also have Black ancestry, plus Dutch, Pennsylvania Dutch (German), and Scots-Irish. It’s certainly possible to verify that using genealogy, but what can DNA testing alone tell us?

How far back can we expect to find ethnicities descending from particular ancestors?

In this table, you can see at each generation how many ancestors you have in that generation, plus the percentage of DNA, on average, you would inherit from each ancestor.

All of the major DNA testing companies can potentially pick up small trace percentages, but they don’t always. Sometimes one company does, and another doesn’t. So, if John has one sixth-generation Native American ancestor, he would carry about 1.56% Native DNA, if any.

  • Sometimes a specific ethnicity is not found because, thanks to random recombination, you didn’t inherit any of that DNA from those ancestors. This is why testing your parents, grandparents, aunts, uncles, and siblings can be very important. They share your same ancestors and may have inherited DNA that you didn’t that’s very relevant to your search.
  • Sometimes it’s not found because the reference populations and algorithms at that testing company aren’t able to detect that population or identify it accurately, especially at trace levels. Every DNA testing company establishes their own reference populations and writes internal, proprietary ethnicity analysis algorithms.
  • Sometimes it’s not found because your ancestor wasn’t Native or from that specific population.
  • Sometimes it’s there, but your population is called something you don’t expect.

For example, you may find Scandinavian when your ancestor was from England or Ireland. The Vikings raided the British Isles, so while some small amount of Scandinavian is not what you expect, that doesn’t mean it‘s wrong. However, if all of your family is from England, it’s not reasonable to have entirely Scandinavian ethnicity results.

It’s also less likely as each generation passes by that the information about their origins gets handed down accurately to following generations. Most non-genealogists don’t know the names of their great-grandparents, let alone where their ancestors were from.

Using a 25-year average generation length, by the 4th generation, shown in the chart above, you have 16 ancestors who lived approximately 100 years before your parents were born, so someplace in the mid-1800s. It’s unlikely for oral history from that time to survive intact. It’s even less likely from a century years earlier, where in the 7th generation, you have 128 total ancestors.

The best way to validate the accuracy of your ethnicity estimates is by researching your genealogy. Of course, you need to take an ethnicity test, or two, in order to have results to validate.

Ethnicity has a lot more to offer than just percentages.

Best Autosomal Tests for Native Ethnicity

Based on my experience with people who have confirmed Native ancestry, the two best tests to detect Native American ethnicity, especially in smaller percentages, are both FamilyTreeDNA and 23andMe.

Click images to enlarge

In addition to percentages, both 23andMe and FamilyTreeDNA provide chromosome painting for ethnicity, along with segment information in download files. In other words, they literally paint your ethnicity results on your chromosomes.

They then provide you with a file with the “addresses” of those ethnicities on your chromosomes, which means you can figure out which ancestors contributed those ethnicity segments.

The person in the example above, a tester at FamilyTreeDNA, is highly admixed with ancestors from European regions, African regions and Native people from South America.

Trace amounts of Native American with a majority of European heritage would appear more like this.

You can use this information to paint your chromosome segments at DNAPainter, along with your matching segments to other testers where you can identify your common ancestors. This is why providing trees is critically important – DNA plus ancestor identification with our matches is how we confirm our ancestry.

This combination allows you to identify which Native (or another ethnicity) segments descended from which ancestors. I was able to determine which ancestor provided that pink Native American segment on chromosome 1 on my mother’s side.

I’ve provided instructions for painting ethnicity segments to identify their origins in specific ancestors, here.

Autosomal and Genealogy

You may have noticed that we’ve now drifted into the genealogy realm of autosomal DNA testing. Ethnicity is nice, but if you want to know who those segments came from, you’ll need:

  • Autosomal test matching to other people
  • To identify your common ancestor with as many matches as you can
  • To match at a company who provides you with segment information for each match
  • To work with DNAPainter, which is very easy

The great news is that you can do all of that using the autosomal tests you took for ethnicity, except at Ancestry who does not provide segment information.

Best Autosomal Test for Matching Other Testers

The best autosomal test for matching may be different for everyone. Let’s look at some of the differentiators and considerations.

If you’re basing a testing recommendation solely on database size, which will probably correlate to more matches, then the DNA testing vendors fall into this order:

If you’re basing that recommendation on the BEST, generally meaning the closest matches for you, there’s no way of knowing ahead of time. At each of the four DNA testing companies, I have very good matches who have not tested elsewhere. If I weren’t in all four databases, I would have missed many valuable matches.

If you’re basing that recommendation on which vendor began testing earliest, meaning they have many tests from people who are now deceased, so you won’t find their autosomal tests in other databases that don’t accept uploads, the recommended testing company order would be:

If you’re basing that recommendation on matches to people who live in other countries, the order would be:

Ancestry and 23andMe are very distant third/fourth because they did not sell widely outside the US initially and still don’t sell in as many countries as the others, meaning their testers’ geography is more limited. However, Ancestry is also prevalent in the UK.

If you’re basing that recommendation on segment information and advanced tools that allow you to triangulate and confirm your genetic link to specific ancestors, the order would be:

Ancestry does NOT provide any segment information.

If you’re basing that recommendation on unique tools provided by each vendor, every vendor has something very beneficial that the others don’t.

In other words, there’s really no clear-cut answer for which single autosomal DNA test to order. The real answer is to be sure you’re fishing in all the ponds. The fish are not the same. Unique people test at each of those companies daily who will never be found in the other databases.

Test at or upload your DNA to all four DNA testing companies, plus GEDmatch. Step-by-step instructions for downloading your raw data file and uploading it to the DNA testing companies who accept uploads can be found, here.

Test or Upload

Not all testing companies accept uploads of raw autosomal DNA data files from other companies. The good news is that some do, and it’s free to upload and receive matches.

Two major DNA testing companies DO NOT accept uploads from other companies. In other words, you have to test at that company:

Two testing companies DO accept uploads from the other three companies. Uploads and matching are free, and advanced features can be unlocked very cost effectively.

  • FamilyTreeDNA – free matching and $19 unlock for advanced features
  • MyHeritage – free matching and $29 unlock.for advanced features

I recommend testing at both 23andMe and Ancestry and uploading one of those files to both FamilyTreeDNA and MyHeritage, then purchasing the respective unlocks.

GEDmatch

GEDmatch is a third-party matching site, not a DNA testing company. Consider uploading to GEDmatch because you may find matches from Ancestry who have uploaded to GEDmatch, giving you access to matching segment information.

Other Types of DNA

John provided additional information that may prove to be VERY useful. Both Y-DNA and mitochondrial DNA can be tested as well and may prove to be more useful than autosomal to positively identify the origins of those two specific lines.

Let’s assume that John takes an autosomal test and discovers that indeed, the 3/16th Native estimate was close. 3/16th equates to about 18% Native which would mean that three of his 16 great-great-grandparents were Native.

John told us that his Grandmother Jones was supposed to be 100% Native.

At the great-great-grandparent level, John has 16 ancestors, so eight on his mother’s side, four from maternal grandmother Jones and four from his maternal grandfather Davis.

John carries the mitochondrial DNA of his mother (red boxes and arrows,) and her mother, through a direct line of females back in time. John also carries the Y-DNA of his father (dark blue box, at left above, and blue arrows below.)

Unlike autosomal DNA which is admixed in every generation, mitochondrial DNA (red arrows) is inherited from that direct matrilineal line ONLY and never combines with the DNA of the father. Mothers give their mitochondrial DNA to both sexes of their children, but men never contribute their mitochondrial DNA to offspring. Everyone has their mother’s mitochondrial DNA.

Because it never recombines with DNA from the father, so is never “watered down,” we can “see” much further back in time, even though we can’t yet identify those ancestors.

However, more importantly, in this situation, John can test his own mitochondrial DNA that he inherited from his mother, who inherited it from her mother, to view her direct matrilineal line.

John’s mitochondrial DNA haplogroup that will be assigned during testing tells us unquestionably whether or not his direct matrilineal ancestor was Native on her mother’s line, or not. If not, it may well tell us where that specific line originated.

You can view the countries around the world where Y-DNA haplogroups are found, here, and mitochondrial haplogroups, here.

If John’s mitochondrial DNA haplogroup is Native, that confirms that one specific line is Native. If he can find other testers in his various lines to test either their Y-DNA or mitochondrial DNA, John can determine if other ancestors were Native too. If not, those tests will reveal the origins of that line, separate from the rest of his genealogical lines.

Although John didn’t mention his father’s line, if he takes a Y-DNA test, especially at the Big Y-700 level, that will also reveal the origins of his direct paternal line. Y-DNA doesn’t combine with the other parent’s DNA either, so it reaches far back in time too.

Y-DNA and mitochondrial DNA tests are laser-focused on one line each, and only one line. You don’t have to try to sort it out of the ethnicity “pot,” wondering which ancestor was or was not Native.

My Recommendation

When putting together a testing strategy, I recommend taking advantage of free uploads and inexpensive unlocks when possible.

  • To confirm Native American ancestry via ethnicity testing, I recommend testing at 23andMe and uploading to FamilyTreeDNA, then purchasing the $19 unlock. The free upload and $19 unlock are less expensive than testing there directly.
  • For matching, I recommend testing at Ancestry and uploading to MyHeritage, then unlocking the MyHeritage advanced features for $29, which is less expensive than retesting. Ancestry does not provide segment information, but MyHeritage (and the others) do.

At this point, John will have taken two DNA tests, but is now in all four databases, plus GEDmatch if he uploads there.

  • For genealogy research on John’s lines to determine whether or not his mother’s lines were Native, I recommend an Ancestry and a MyHeritage records subscription, plus using WikiTree, which is free.
  • To determine if John’s mother’s direct matrilineal female line was Native, I recommend that John order the mitochondrial DNA test at FamilyTreeDNA.
  • When ordering multiple tests, or uploading at FamilyTreeDNA, be sure to upload/order all of one person’s tests on the same DNA kit so that those results can be used in combination with each other.

Both males and females can take autosomal and mitochondrial DNA tests.

  • To discover what he doesn’t know about his direct paternal, meaning John’s surname line – I recommend the Big Y-700 test at FamilyTreeDNA.

Only males can take a Y-DNA test, so women would need to ask their father, brother, or paternal uncle, for example, to test their direct paternal line.

  • If John can find a male Davis from his mother’s line, I recommend that he purchase the Big Y-700 test at FamilyTreeDNA for that person, or check to see if someone from his Davis line may have already tested by viewing the Davis DNA Project. Like with mitochondrial DNA, the Y-DNA haplogroup will tell John the origins of his direct Davis male ancestor – plus matching of course. He will be able to determine if they were Native, and if not, discover the origins of the Davis line.
  • For assigning segments to ancestors and triangulating to confirm descent from a common ancestor, I recommend 23andMe, MyHeritage, FamilyTreeDNA and GEDmatch, paired with DNAPainter as a tool.

Shopping and Research List

Here are the tests and links recommended above:

More Than He Asked

I realize this answer is way more than John expected or even knew to ask. That’s because there is often no “one” or “one best” answer. There are many ways to approach the question after the goal is defined, and the first “answer” received may be a bit out of context.

For example, let’s say John has 2% Native ancestry and took a test at a vendor who didn’t detect it. John would believe he had none. But a different vendor might find that 2%. If it’s on his mother’s direct matrilineal line, mitochondrial DNA testing will confirm, or refute Native, beyond any doubt, regardless of autosomal ethnicity results – but only for that specific ancestral line.

Autosomal DNA can suggest Native across all your DNA, but Y-DNA and mitochondrial DNA confirm it for each individual ancestor.

Even when autosomal testing does NOT show Native American, or African, for example, it’s certainly possible that it’s just too far back in time or has not been passed down during random recombination, but either Y-DNA or mitochondrial DNA will unquestionably confirm (or refute) the ancestry in question if the right person is tested.

This is exactly why I attempt to find a cousin who descends appropriately from every ancestor and provide testing scholarships. It’s important to obtain Y-DNA and mitochondrial DNA information for each ancestor.

Which Test Should I Order?

What steps will help you decide which test or tests to take?

  1. Define your testing goal.
  2. Determine if your Y-DNA or mitochondrial DNA will help answer the question.
  3. Determine if you need to find ancestors another generation or two back in time to get the most benefit from DNA testing. In our example, if John discovered that both of his grandparents were enrolled tribal members, that’s huge, and the tribe might have additional information about his family.
  4. Subscribe to Ancestry and MyHeritage records collections as appropriate to perform genealogical research. Additional information not only provides context for your family, it also provides you with the ability to confirm or better understand your ethnicity results.
  5. Extend your tree so that you can obtain the best results from the three vendors who support trees; Ancestry, FamilyTreeDNA, and MyHeritage. All three use trees combined with DNA tests to provide you with additional information.
  6. Order 23andMe and Ancestry autosomal DNA tests.
  7. Either test at or upload one of those tests to MyHeritage, FamilyTreeDNA, and GEDmatch.
  8. If a male, order the Big Y-700 DNA test. Or, find a male from your ancestral line who has taken or will take that test. I always offer a testing scholarship and, of course, share the exciting results!
  9. Order a mitochondrial DNA test for yourself and for appropriately descended family members to represent other ancestors. Remember that your father (and his siblings) all carry your paternal grandmother’s mitochondrial DNA. That’s often a good place to start after testing your own DNA.
  10. If your parents or grandparents are alive, or aunts and uncles, test their autosomal DNA too. They are (at least) one generation closer to your ancestors than you are and will carry more of your ancestors’ DNA.
  11. Your siblings will carry some of your ancestors’ DNA that you do not, so test them too if both of your parents aren’t available for testing.

Enjoy!!!

DNA: In Search of…Signs of Endogamy

This is the fourth in our series of articles about searching for unknown close family members, specifically; parents, grandparents, or siblings. However, these same techniques can be applied by genealogists to ancestors further back in time as well.

In this article, we discuss endogamy – how to determine if you have it, from what population, and how to follow the road signs.

After introductions, we will be covering the following topics:

  • Pedigree collapse and endogamy
  • Endogamous groups
  • The challenge(s) of endogamy
  • Endogamy and unknown close relatives (parents, grandparents)
  • Ethnicity and Populations
  • Matches
  • AutoClusters
  • Endogamous Relationships
  • Endogamous DNA Segments
  • “Are Your Parents Related?” Tool
  • Surnames
  • Projects
  • Locations
  • Y DNA, Mitochondrial DNA, and Endogamy
  • Endogamy Tools Summary Tables
    • Summary of Endogamy Tools by Vendor
    • Summary of Endogamous Populations Identified by Each Tool
    • Summary of Tools to Assist People Seeking Unknown Parents and Grandparents

What Is Endogamy and Why Does It Matter?

Endogamy occurs when a group or population of people intermarry among themselves for an extended period of time, without the introduction of many or any people from outside of that population.

The effect of this continual intermarriage is that the founders’ DNA simply gets passed around and around, eventually in small segments.

That happens because there is no “other” DNA to draw from within the population. Knowing or determining that you have endogamy helps make sense of DNA matching patterns, and those patterns can lead you to unknown relatives, both close and distant.

This Article

This article serves two purposes.

  • This article is educational and relevant for all researchers. We discuss endogamy using multiple tools and examples from known endogamous people and populations.
  • In order to be able to discern endogamy when we don’t know who our parents or grandparents are, we need to know what signs and signals to look for, and why, which is based on what endogamy looks like in people who know their heritage.

There’s no crystal ball – no definitive “one-way” arrow, but there are a series of indications that suggest endogamy.

Depending on the endogamous population you’re dealing with, those signs aren’t always the same.

If you’re sighing now, I understand – but that’s exactly WHY I wrote this article.

We’re covering a lot of ground, but these road markers are invaluable diagnostic tools.

I’ve previously written about endogamy in the articles:

Let’s start with definitions.

Pedigree Collapse and Endogamy

Pedigree collapse isn’t the same as endogamy. Pedigree collapse is when you have ancestors that repeat in your tree.

In this example, the parents of our DNA tester are first cousins, which means the tester shares great-grandparents on both sides and, of course, the same ancestors from there on back in their tree.

This also means they share more of those ancestors’ DNA than they would normally share.

John Smith and Mary Johnson are both in the tree twice, in the same position as great-grandparents. Normally, Tester Smith would carry approximately 12.5% of each of his great-grandparents’ DNA, assuming for illustration purposes that exactly 50% of each ancestor’s DNA is passed in each generation. In this case, due to pedigree collapse, 25% of Tester Smith’s DNA descends from John Smith, and another 25% descends from Mary Johnson, double what it would normally be. 25% is the amount of DNA contribution normally inherited from grandparents, not great-grandparents.

While we may find first cousin marriages a bit eyebrow-raising today, they were quite common in the past. Both laws and customs varied with the country, time, social norms, and religion.

Pedigree Collapse and Endogamy is NOT the Same

You might think that pedigree collapse and endogamy is one and the same, but there’s a difference. Pedigree collapse can lead to endogamy, but it takes more than one instance of pedigree collapse to morph into endogamy within a population. Population is the key word for endogamy.

The main difference is that pedigree collapse occurs with known ancestors in more recent generations for one person, while endogamy is longer-term and systemic in a group of people.

Picture a group of people, all descended from Tester Smith’s great-grandparents intermarrying. Now you have the beginnings of endogamy. A couple hundred or a few hundred years later, you have true endogamy.

In other words, endogamy is pedigree collapse on a larger scale – think of a village or a church.

My ancestors’ village of Schnait, in Germany, is shown above in 1685. One church and maybe 30 or 40 homes. According to church and other records, the same families had inhabited this village, and region, for generations. It’s a sure bet that both pedigree collapse and endogamy existed in this small community.

If pedigree collapse happens over and over again because there are no other people within the community to marry, then you have endogamy. In other words, with endogamy, you assuredly DO have historical pedigree collapse, generally back in time, often before you can identify those specific ancestors – because everyone descends from the same set of founders.

Endogamy Doesn’t Necessarily Indicate Recent Pedigree Collapse

With deep, historic endogamy, you don’t necessarily have recent pedigree collapse, and in fact, many people do not. Jewish people are a good example of this phenomenon. They shared ancestors for hundreds or thousands of years, depending on which group we are referring to, but in recent, known, generations, many Jewish people aren’t related. Still, their DNA often matches each other.

The good news is that there are telltale signs and signals of endogamy.

The bad news is that not all of these are obvious, meaning as an aid to people seeking clues about unknown close relatives, and other “signs” aren’t what they are believed to be.

Let’s step through each endogamy identifier, or “hint,” and then we will review how we can best utilize this information.

First, let’s take a look at groups that are considered to be endogamous.

Endogamous Groups

Jewish PeopleSpecifically groups that were isolated from other groups of Jewish (and other) people; Ashkenazi (Germany, Northern France, and diaspora), Sephardic (Spanish, Iberia, and diaspora), Mizrahi (Israel, Middle Eastern, and diaspora,) Ethiopian Jews, and possibly Jews from other locations such as Mountain Jews from Kazakhstan and the Caucasus.

AcadiansDescendants of about 60 French families who settled in “Acadia” beginning about 1604, primarily on the island of Nova Scotia, and intermarried among themselves and with the Mi’kmaq people. Expelled by the English in 1755, they were scattered in groups to various diasporic regions where they continued to intermarry and where their descendants are found today. Some Acadians became the Cajuns of Louisiana.

Anabaptist Protestant FaithsAmish, Mennonite, and Brethren (Dunkards) and their offshoots are Protestant religious sects founded in Europe in the 14th, 15th, and 16th centuries on the principle of baptizing only adults or people who are old enough to choose to follow the faith, or rebaptizing people who had been previously baptized as children. These Anabaptist faiths tend to marry within their own group or church and often expel those who marry outside of the faith. Many emigrated to the American colonies and elsewhere, seeking religious freedom. Occasionally those groups would locate in close proximity and intermarry, but not marry outside of other Anabaptist denominations.

Native American (Indigenous) People – all indigenous peoples found in North and South America before European colonization descended from a small number of original founders who probably arrived at multiple times.

Indigenous Pacific Islanders – Including indigenous peoples of Australia, New Zealand, and Hawaii prior to colonization. They are probably equally as endogamous as Native American people, but I don’t have specific examples to share.

Villages – European or other villages with little inflow or whose residents were restricted from leaving over hundreds of years.

Other groups may have significant multiple lines of pedigree collapse and therefore become endogamous over time. Some people from Newfoundland, French Canadians, and Mormons (Church of Jesus Christ of Latter-Day Saints) come to mind.

Endogamy is a process that occurs over time.

Endogamy and Unknown Relatives

If you know who your relatives are, you may already know you’re from an endogamous population, but if you’re searching for close relatives, it’s helpful to be able to determine if you have endogamous heritage, at least in recent generations.

If you know nothing about either parent, some of these tools won’t help you, at least not initially, but others will. However, as you add to your knowledge base, the other tools will become more useful.

If you know the identity of one parent, this process becomes at least somewhat easier.

In future articles, we will search specifically for parents and each of your four grandparents. In this article, I’ll review each of the diagnostic tools and techniques you can use to determine if you have endogamy, and perhaps pinpoint the source.

The Challenge

People with endogamous heritage are related in multiple, unknown ways, over many generations. They may also be related in known ways in recent generations.

If both of your parents share the SAME endogamous culture or group of relatives:

  • You may have significantly more autosomal DNA matches than people without endogamy, unless that group of people is under-sampled. Jewish people have significantly more matches, but Native people have fewer due to under-sampling.
  • You may experience a higher-than-normal cM (centiMorgan) total for estimated relationships, especially more distant relationships, 3C and beyond.
  • You will have many matches related to you on both your maternal and paternal sides.
  • Parts of your autosomal DNA will be the same on both your mother’s and father’s sides, meaning your DNA will be fully identical in some locations. (I’ll explain more in a minute.)

If either (or both) of your parents are from an endogamous population, you:

  • Will, in some cases, carry identifying Y and mitochondrial DNA that points to a specific endogamous group. This is true for Native people, can be true for Jewish people and Pacific Islanders, but is not true for Anabaptist people.

One Size Does NOT Fit All

Please note that there is no “one size fits all.”

Each or any of these tools may provide relevant hints, depending on:

  • Your heritage
  • How many other people have tested from the relevant population group
  • How many close or distant relatives have tested
  • If your parents share the same heritage
  • Your unique DNA inheritance pattern
  • If your parents, individually, were fully endogamous or only partly endogamous, and how far back generationally that endogamy occurred

For example, in my own genealogy, my maternal grandmother’s father was Acadian on his father’s side. While I’m not fully endogamous, I have significantly more matches through that line proportionally than on my other lines.

I have Brethren endogamy on my mother’s side via her paternal grandmother.

Endogamous ancestors are shown with red stars on my mother’s pedigree chart, above. However, please note that her maternal and paternal endogamous ancestors are not from the same endogamous population.

However, I STILL have fewer matches on my mother’s side in total than on my father’s side because my mother has recent Dutch and recent German immigrants which reduces her total number of matches. Neither of those lines have had as much time to produce descendants in the US, and Europe is under-sampled when compared with the US where more people tend to take DNA tests because they are searching for where they came from.

My father’s ancestors have been in the US since it was a British Colony, and I have many more cousins who have tested on his side than mother’s.

If you looked at my pedigree chart and thought to yourself, “that’s messy,” you’d be right.

The “endogamy means more matches” axiom does not hold true for me, comparatively, between my parents – in part because my mother’s German and Dutch lines are such recent immigrants.

The number of matches alone isn’t going to tell this story.

We are going to need to look at several pieces and parts for more information. Let’s start with ethnicity.

Ethnicity and Populations

Ethnicity can be a double-edged sword. It can tell you exactly nothing you couldn’t discern by looking in the mirror, or, conversely, it can be a wealth of information.

Ethnicity reveals the parts of the world where your ancestors originated. When searching for recent ancestors, you’re most interested in majority ethnicity, meaning the 50% of your DNA that you received from each of your parents.

Ethnicity results at each vendor are easy to find and relatively easy to understand.

This individual at FamilyTreeDNA is 100% Ashkenazi Jewish.

If they were 50% Jewish, we could then estimate, and that’s an important word, that either one of their parents was fully Jewish, and not the other, or that two of their grandparents were Jewish, although not necessarily on the same side.

On the other hand, my mother’s ethnicity, shown below, has nothing remarkable that would point to any majority endogamous population, yet she has two.

The only hint of endogamy from ethnicity would be her ~1% Americas, and that isn’t relevant for finding close relatives. However, minority ancestry is very relevant for identifying Native ancestors, which I wrote about, here.

You can correlate or track your ethnicity segments to specific ancestors, which I discussed in the article, Native American & Minority Ancestors Identified Using DNAPainter Plus Ethnicity Segments, here.

Since I wrote that article, FamilyTreeDNA has added the feature of ethnicity or population Chromosome Painting, based on where each of your populations fall on your chromosomes.

In this example on chromosome 1, I have European ancestry (blue,) except for the pink Native segment, which occurs on the following segment in the same location on my mother’s chromosome 1 as well.

Both 23andMe, and FamilyTreeDNA provide chromosome painting AND the associated segment information so you can identify the relevant ancestors.

Ancestry is in the process of rolling out an ethnicity painting feature, BUT, it has no segment or associated matching information. While it’s interesting eye candy, it’s not terribly useful beyond the ethnicity information that Ancestry already provides. However, Jonny Perl at DNAPainter has devised a way to estimate Ancestry’s start and stop locations, here. Way to go Jonny!

Now all you need to do is convince your Ancestry matches to upload their DNA file to one of the three databases, FamilyTreeDNA, MyHeritage, and GEDMatch, that accept transfers, aka uploads. This allows matching with segment data so that you can identify who matches you on that segment, track your ancestors, and paint your ancestral segments at DNAPainter.

I provided step-by-step instructions, here, for downloading your raw DNA file from each vendor in order to upload the file to another vendor.

Ethnicity Sides

Three of the four DNA testing vendors, 23andMe, FamilyTreeDNA, and recently, Ancestry, attempt to phase your ethnicity DNA, meaning to assign it to one parental “side” or the other – both in total and on each chromosome.

Here’s Ancestry’s SideView, where your DNA is estimated to belong to parent 1 and parent 2. I detailed how to determine which side is which, here, and while that article was written specifically pertaining to Ancestry’s SideView, the technique is relevant for all the vendors who attempt to divide your DNA into parents, a technique known as phasing.

I say “attempt” because phasing may or may not be accurate, meaning the top chromosome may not always be parent 1, and the bottom chromosome may not always be chromosome 2.

Here’s an example at 23andMe.

See the two yellow segments. They are both assigned as Native. I happen to know one is from the mother and one is from the father, yet they are both displayed on the “top” chromosome, which one would interpret to be the same parent.

I am absolutely positive this is not the case because this is a close family member, and I have the DNA of the parent who contributed the Native segment on chromosome 1, on the top chromosome. That parent does not have a Native segment on chromosome 2 to contribute. So that Native segment had to be contributed by the other parent, but it’s also shown on the top chromosome.

The DNA segments circled in purple belong together on the same “side” and were contributed to the tester by the same parent. The Native segment on chromosome 2 abuts a purple African segment, suggesting perhaps that the ancestor who contributed that segment was mixed between those ethnicities. In the US, that suggests enslavement.

The other African segments, circled, are shown on the second chromosome in each pair.

To be clear, parent 1 is not assigned by the vendors to either mother or father and will differ by person. Your parent 1, or the parent on the top chromosome may be your mother and another person’s parent 1 may be their father.

As shown in this example, parents can vary by chromosome, a phenomenon known as “strand swap.” Occasionally, the DNA can even be swapped within a chromosome assignment.

You can, however, get an idea of the division of your DNA at any specific location. As shown above, you can only have a maximum of two populations of DNA on any one chromosome location.

In our example above, this person’s majority ancestry is European (blue.) On each chromosome where we find a minority segment, the opposite chromosome in the same location is European, meaning blue.

Let’s look at another example.

At FamilyTreeDNA, the person whose ethnicity painting is shown below has a Native American (pink) ancestor on their father’s side. FamilyTreeDNA has correctly phased or identified their Native segments as all belonging to the second chromosome in each pair.

Looking at chromosome 18, for example, most of their father’s chromosome is Native American (pink). The other parent’s chromosome is European (dark blue) at those same locations.

If one of the parents was of one ethnicity, and the other parent is a completely different ethnicity, then one bar of each chromosome would be all pink, for example, and one would be entirely blue, representing the other ethnicity.

Phasing ethnicity or populations to maternal and paternal sides is not foolproof, and each chromosome is phased individually.

Ethnicity can, in some cases, give you a really good idea of what you’re dealing with in terms of heritage and endogamy.

If someone had an Ashkenazi Jewish father and European mother, for example, one copy of each chromosome would be yellow (Ashkenazi Jewish), and one would be blue (European.)

However, if each of their parents were half European Jewish and half European (not Jewish), then their different colored segments would be scattered across their entire set of chromosomes.

In this case, both of the tester’s parents are mixed – European Jewish (green) and Western Europe (blue.) We know both parents are admixed from the same two populations because in some locations, both parents contributed blue (Western Europe), and in other locations, both contributed Jewish (green) segments.

Both MyHeritage and Ancestry provide a secondary tool that’s connected to ethnicity, but different and generally in more recent times.

Ancestry’s DNA Communities

While your ethnicity may not point to anything terribly exciting in terms of endogamy, Genetic Communities might. Ancestry says that a DNA Community is a group of people who share DNA because their relatives recently lived in the same place at the same time, and that communities are much smaller than ethnicity regions and reach back only about 50-300 years.

Based on the ancestors’ locations in the trees of me and my matches, Ancestry has determined that I’m connected to two communities. In my case, the blue group is clearly my father’s line. The orange group could be either parent, or even a combination of both.

My endogamous Brethren could be showing up in Maryland, Pennsylvania, and Ohio, but it’s uncertain, in part, because my father’s ancestral lines are found in Virginia, West Virginia, and Maryland too.

These aren’t useful for me, but they may be more useful for fully endogamous people, especially in conjunction with ethnicity.

My Acadian cousin’s European ethnicity isn’t informative.

However, viewing his DNA Communities puts his French heritage into perspective, especially combined with his match surnames.

I wrote about DNA Communities when it was introduced with the name Genetic Communities, here.

MyHeritage’s Genetic Groups

MyHeritage also provides a similar feature that shows where my matches’ ancestors lived in the same locations as mine.

One difference, though, is that testers can adjust their ethnicity results confidence level from high, above, to low, below where one of my Genetic Groups overlaps my ethnicity in the Netherlands.

You can also sort your matches by Genetic Groups.

The results show you not only who is in the group, but how many of your matches are in that group too, which provides perspective.

I wrote about Genetic Groups, here.

Next, let’s look at how endogamy affects your matches.

Matches

The number of matches that a person has who is from an entirely endogamous community and a person with no endogamy may be quite different.

FamilyTreeDNA provides a Family Matching feature that triangulates your matches and assigns them to your paternal or maternal side by using known matches that you have linked to their profile cards in your tree. You must link people for the Family Matching feature known as “bucketing” to be enabled.

The people you link are then processed for shared matches on the same chromosome segment(s). Triangulated individuals are then deposited in your maternal, paternal, and both buckets.

Obviously, your two parents are the best people to link, but if they haven’t tested (or uploaded their DNA file from another vendor) and you have other known relatives, link them using the Family Tree tab at the top of your personal page.

I uploaded my Ancestry V4 kit to use as an example for linking. Let’s pretend that’s my sister. If I had not already linked my Ancestry V4 kit to “my sister’s” profile card, I’d want to do that and link other known individuals the same way. Just drag and drop the match to the correct profile card.

Note that a full or half sibling will be listed as such at FamilyTreeDNA, but an identical twin will show as a potential parent/child match to you. You’re much more likely to find a parent than an identical twin, but just be aware.

I’ve created a table of FamilyTreeDNA bucketed match results, by category, comparing the number of matches in endogamous categories with non-endogamous.

Total Matches Maternal Matches Paternal Matches Both % Both % DNA Unassigned
100% Jewish 34,637 11,329 10,416 4,806 13.9 23.3
100% Jewish 32,973 10,700 9,858 4,606 14 23.7
100% Jewish 32,255 9,060 10,970 3,892 12 25.8
75% Jewish 24,232 11,846 Only mother linked Only mother linked Only mother linked
100% Acadian 8093 3826 2299 1062 13 11
100% Acadian 7828 3763 1825 923 11.8 17
Not Endogamous 6760 3845 1909 13 0.19 14.5
Not Endogamous 7723 1470 3317 6 0.08 38
100% Native American 1,115 Unlinked Unlinked Unlinked
100% Native American 885 290 Unknown Can’t calculate without at least one link on both sides

The 100% Jewish, Acadian, and Not Endogamous testers both have linked their parents, so their matches, if valid (meaning not identical by chance, which I discussed here,) will match them plus one or the other parent.

One person is 75% Jewish and has only linked their Jewish mother.

The Native people have not tested their parents, and the first Native person has not linked anyone in their tree. The second Native person has only linked a few maternal matches, but their mother has not tested. They are seeking their father.

It’s very difficult to find people who are fully Native as testers. Furthermore, Native people are under-sampled. If anyone knows of fully Native (or other endogamous) people who have tested and linked their parents or known relatives in their trees, and will allow me to use their total match numbers anonymously, please let me know.

As you can see, Jewish, Acadian, and Native people are 100% endogamous, but many more Jewish people than Native people have tested, so you CAN’T judge endogamy by the total number of matches alone.

In fact, in order:

  • Fully Jewish testers have about 4-5 times as many matches as the Acadian and Non-endogamous testers
  • Acadian and Non-endogamous testers have about 5-6 times as many matches as the Native American testers
  • Fully Jewish people have about 30 times more matches than the Native American testers

If a person’s endogamy with a particular population is only on their maternal or paternal side, they won’t have a significant number of people related to both sides, meaning few people will fall into the “Both” bucket. People that will always be found in the ”Both” bucket are full siblings and their descendants, along with descendants of the tester, assuming their match is linked to their profiles in the tester’s tree.

In the case of our Jewish testers, you can easily see that the “Both” bucket is very high. The Acadians are also higher than one would reasonably expect without endogamy. A non-endogamous person might have a few matches on both sides, assuming the parents are not related to each other.

A high number of “Both” matches is a very good indicator of endogamy within the same population on both parents’ sides.

The percentage of people who are assigned to the “Both” bucket is between 11% and 14% in the endogamous groups, and less than 1% in the non-endogamous group, so statistically not relevant.

As demonstrated by the Native people compared to the Jewish testers, the total number of matches can be deceiving.

However, being related to both parents, as indicated by the “Both” bucket, unless you have pedigree collapse, is a good indicator of endogamy.

Of course, if you don’t know who your relatives are, you can’t link them in your tree, so this type of “hunt” won’t generally help people seeking their close family members.

However, you may notice that you’re matching people PLUS both of their parents. If that’s the case, start asking questions of those matches about their heritage.

A very high number of total matches, as compared to non-endogamous people, combined with some other hints might well point to Jewish heritage.

I included the % DNA Unassigned category because this category, when both parents are linked, is the percentage of matches by chance, meaning the match doesn’t match either of the tester’s parents. All of the people with people listed in “Both” categories have linked both of their parents, not just maternal and paternal relatives.

Matching Location at MyHeritage

MyHeritage provides a matching function by location. Please note that it’s the location of the tester, but that may still be quite useful.

The locations are shown in the most-matches to least-matches order. Clicking on the location shows the people who match you who are from that location. This would be the most useful in situations where recent immigration has occurred. In my case, my great-grandfather from the Netherlands arrived in the 1860s, and my German ancestors arrived in the 1850s. Neither of those groups are endogamous, though, unless it would be on a village level.

AutoClusters

Let’s shift to Genetic Affairs, a third-party tool available to everyone.

Using their AutoCluster function, Genetic Affairs clusters your matches together who match both each other and you.

This is an example of the first few clusters in my AutoCluster. You can see that I have several colored clusters of various sizes, but none are huge.

Compare that to the following endogamous cluster, sample courtesy of EJ Blom at Genetic Affairs.

If your AutoCluster at Genetic Affairs looks something like this, a huge orange blob in the upper left hand corner, you’re dealing with endogamy.

Please also note that the size of your cluster is also a function of both the number of testers and the match threshold you select. I always begin by using the defaults. I wrote about using Genetic Affairs, here.

If you tested at or transferred to MyHeritage, they too license AutoClusters, but have optimized the algorithm to tease out endogamous matches so that their Jewish customers, in particular, don’t wind up with a huge orange block of interrelated people.

You won’t see the “endogamy signature” huge cluster in the corner, so you’re less likely to be able to discern endogamy from a MyHeritage cluster alone.

The commonality between these Jewish clusters at MyHeritage is that they all tend to be rather uniform in size and small, with lots of grey connecting almost all the blocks.

Grey cells indicate people who match people in two colored groups. In other words, there is often no clear division in clusters between the mother’s side and the father’s side in Jewish clusters.

In non-endogamous situations, even if you can’t identify the parents, the clusters should still fall into two sides, meaning a group of clusters for each parent’s side that are not related to each other.

You can read more about Genetic Affairs clusters and their tools, here. DNAGedcom.com also provides a clustering tool.

Endogamous Relationships

Endogamous estimated relationships are sometimes high. Please note the word, “sometimes.”

Using the Shared cM Project tool relationship chart, here, at DNAPainter, people with heavy endogamy will discover that estimated relationships MAY be on the high side, or the relationships may, perhaps, be estimated too “close” in time. That’s especially true for more distant relationships, but surprisingly, it’s not always true. The randomness of inheritance still comes into play, and so do potential unknown relatives. Hence, the words “may” are bolded and underscored.

Unfortunately, it’s often stated as “conventional wisdom” that Jewish matches are “always” high, and first cousins appear as siblings. Let’s see what the actual data says.

At DNAPainter, you can either enter the amount of shared DNA (cM), or the percent of shared DNA, or just use the chart provided.

I’ve assembled a compilation of close relationships in kits that I have access to or from people who were generous enough to share their results for this article.

I’ve used Jewish results, which is a highly endogamous population, compared with non-endogamous testers.

The “Jewish Actual” column reports the total amount of shared DNA with that person. In other words, someone to their grandparent. The Average Range is the average plus the range from DNAPainter. The Percent Difference is the % difference between the actual number and the DNAPainter average.

You’ll see fully Jewish testers, at left, matching with their family members, and a Non-endogamous person, at right, matching with their same relative.

Relationship Jewish Actual Percent Difference than Average Average -Range Non-endogamous Actual Percent Difference than Average
Grandparent 2141 22 1754 (984-2482) 1742 <1 lower
Grandparent 1902 8.5 1754 (984-2482) 1973 12
Sibling 3039 16 2613 (1613-3488) 2515 3.5 lower
Sibling 2724 4 2613 (1613-3488) 2761 5.5
Half-Sibling 2184 24 1759 (1160-2436) 2127 21
Half-Sibling 2128 21 1759 (1160-2436) 2352 34
Aunt/Uncle 2066 18.5 1741 (1201-2282) 1849 6
Aunt/Uncle 2031 16.5 1741 (1201-2282) 2097 20
1C 1119 29 866 (396-1397) 959 11
1C 909 5 866 (396-1397) 789 9 lower
1C1R 514 19 433 (102-980) 467 8
1C1R 459 6 433 (102-980) 395 9 lower

These totals are from FamilyTreeDNA except one from GEDMatch (one Jewish Half-sibling).

Totals may vary by vendor, even when matching with the same person. 23andMe includes the X segments in the total cMs and also counts fully identical segments twice. MyHeritage imputation seems to err on the generous side.

However, in these dozen examples:

  • You can see that the Jewish actual amount of DNA shared is always more than the average in the estimate.
  • The red means the overage is more than 100 cM larger.
  • The percentage difference is probably more meaningful because 100 cM is a smaller percentage of a 1754 grandparent connection than compared to a 433 cM 1C1R.

However, you can’t tell anything about endogamy by just looking at any one sample, because:

  • Some of the Non-Endogamous matches are high too. That’s just the way of random inheritance.
  • All of the actual Jewish match numbers are within the published ranges, but on the high side.

Furthermore, it can get more complex.

Half Endogamous

I requested assistance from Jewish genealogy researchers, and a lovely lady, Sharon, reached out, compiled her segment information, and shared it with me, granting permission to share with you. A HUGE thank you to Sharon!

Sharon is half-Jewish via one parent, and her half-sibling is fully Jewish. Their half-sibling match to each other at Ancestry is 1756 cM with a longest segment of 164 cM.

How does Jewish matching vary if you’re half-Jewish versus fully Jewish? Let’s look at 21 people who match both Sharon and her fully Jewish half-sibling.

Sharon shared the differences in 21 known Jewish matches with her and her half-sibling. I’ve added the Relationship Estimate Range from DNAPainter and colorized the highest of the two matches in yellow. Bolding in the total cM column shows a value above the average range for that relationship.

Total Matching cMs is on the left, with Longest Segment on the right.

While this is clearly not a scientific study, it is a representative sample.

The fully Jewish sibling carries more Jewish DNA, which is available for other Jewish matches to match as a function of endogamy (identical by chance/population), so I would have expected the fully Jewish sibling to match most if not all Jewish testers at a higher level than the half-Jewish sibling.

However, that’s not universally what we see.

The fully Jewish sibling is not always the sibling with the highest number of matches to the other Jewish testers, although the half-Jewish tester has the larger “Longest Segment” more often than not.

Approximately two-thirds of the time (13/21), the fully Jewish person does have a higher total matching cM, but about one-third of the time (8/21), the half-Jewish sibling has a higher matching cM.

About one-fourth of the time (5/21), the fully Jewish sibling has the longest matching segment, and about two-thirds of the time (13/21), the half-Jewish sibling does. In three cases, or about 14% of the time, the longest segment is equal which may indicate that it’s the same segment.

Because of endogamy, Jewish matches are more likely to have:

  • Larger than average total cM for the specific relationship
  • More and smaller matching segments

However, as we have seen, neither of those are definitive, nor always true. Jewish matches and relationships are not always overestimated.

Ancestry and Timber

Please note that Ancestry downweights some matches by removing some segments using their Timber algorithm. Based on my matches and other accounts that I manage, Ancestry does not downweight in the 2-3rd cousin category, which is 90 cM and above, but they do begin downweighting in the 3-4th cousin category, below 90 cM, where my “Extended Family” category begins.

If you’ve tested at Ancestry, you can check for yourself.

By clicking on the amount of DNA you share with your match on your match list at Ancestry, shown above, you will be taken to another page where you will be able to view the unweighted shared DNA with that match, meaning the amount of DNA shared before the downweighting and removal of some segments, shown below.

Given the downweighting, and the information in the spreadsheet provided by Sharon, it doesn’t appear that any of those matches would have been in a category to be downweighted.

Therefore, for these and other close matches, Timber wouldn’t be a factor, but would potentially be in more distant matches.

Endogamous Segments

Endogamous matches tend to have smaller and more segments. Small amounts of matching DNA tend to skew the total DNA cM upwards.

How and why does this happen?

Ancestral DNA from further back in time tends to be broken into smaller segments.

Sometimes, especially in endogamous situations, two smaller segments, at one time separated from each other, manage to join back together again and form a match, but the match is only due to ancestral segments – not because of a recent ancestor.

Please note that different vendors have different minimum matching cM thresholds, so smaller matches may not be available at all vendors. Remember that factors like Timber and imputation can affect matching as well.

Let’s take a look at an example. I’ve created a chart where two ancestors have their blue and pink DNA broken into 4 cM segments.

They have children, a blue child and a pink child, and the two children, shown above, each inherited the same blue 4 cM segment and the same pink 4 cM segment from their respective parents. The other unlabeled pink and blue segments are not inherited by these two children, so those unlabeled segments are irrelevant in this example.

The parents may have had other children who inherited those same 4 cM labeled pink and blue segments as well, and if not, the parents’ siblings were probably passing at least some of the same DNA down to their descendants too.

The blue and pink children had children, and their children had children – for several generations.

Time passed, and their descendants became an endogamous community. Those pink and blue 4 cM segments may at some time be lost during recombination in the descendants of each of their children, shown by “Lost pink” and “Lost blue.”

However, because there is only a very limited amount of DNA within the endogamous community, their descendants may regain those same segments again from their “other parent” during recombination, downstream.

In each generation, the DNA of the descendant carrying the original blue or pink DNA segment is recombined with their partner. Given that the partners are both members of the same endogamous community, the two people may have the same pink and/or blue DNA segments. If one parent doesn’t carry the pink 4 cM segment, for example, their offspring may receive that ancestral pink segment from the other parent.

They could potentially, and sometimes do, receive that ancestral segment from both parents.

In our example, the descendants of the blue child, at left, lost the pink 4 cM segment in generation 3, but a few generations later, in generation 11, that descendant child inherited that same pink 4 cM segment from their other parent. Therefore, both the 4 cM blue and 4 cM pink segments are now available to be inherited by the descendants in that line. I’ve shown the opposite scenario in the generational inheritance at right where the blue segment is lost and regained.

Once rejoined, that pink and blue segment can be passed along together for generations.

The important part, though, is that once those two segments butt up against each other again during recombination, they aren’t just two separate 4 cM segments, but one segment that is 8 cM long – that is now equal to or above the vendors’ matching threshold.

This is why people descended from endogamous populations often have the following matching characteristics:

  • More matches
  • Many smaller segment matches
  • Their total cM is often broken into more, smaller segments

What does more, smaller segments, look like, exactly?

More, Smaller Segments

All of our vendors except Ancestry have a chromosome browser for their customers to compare their DNA to that of their matches visually.

Let’s take a look at some examples of what endogamous and non-endogamous matches look like.

For example, here’s a screen shot of a random Jewish second cousin match – 298 cM total, divided into 12 segments, with a longest segment of 58 cM,

A second Jewish 2C with 323 cM total, across 19 segments, with a 69 cM longest block.

A fully Acadian 2C match with 600 cM total, across 27 segments, with a longest segment of 69 cM.

A second Acadian 2C with 332 cM total, across 20 segments, with a longest segment of 42 cM.

Next, a non-endogamous 2C match with 217 cM, across 7 segments, with a longest segment of 72 cM.

Here’s another non-endogamous 2C example, with 169 shared cM, across 6 segments, with a longest segment of 70 cM.

Here’s the second cousin data in a summary table. The take-away from this is the proportion of total segments

Tester Population Total cM Longest Block Total Segments
Jewish 2C 298 58 12
Jewish 2C 323 69 19
Acadian 2C 600 69 27
Acadian 2C 332 42 20
Non-endogamous 2C 217 72 7
Non-endogamous 2C 169 70 6

You can see more examples and comparisons between Native American, Jewish and non-endogamous DNA individuals in the article, Concepts – Endogamy and DNA Segments.

I suspect that a savvy mathematician could predict endogamy based on longest block and total segment information.

Lara Diamond, a mathematician, who writes at Lara’s Jewnealogy might be up for this challenge. She just published compiled matching and segment information in her Ashkenazic Shared DNA Survey Results for those who are interested. You can also contribute to Laura’s data, here.

Endogamy, Segments, and Distant Relationships

While not relevant to searching for close relatives, heavily endogamous matches 3C and more distant, to quote one of my Jewish friends, “dissolve into a quagmire of endogamy and are exceedingly difficult to unravel.”

In my own Acadian endogamous line, I often simply have to label them “Acadian” because the DNA tracks back to so many ancestors in different lines. In other words, I can’t tell which ancestor the match is actually pointing to because the same DNA segments or segments is/are carried by several ancestors and their descendants due to founder effect.

The difference with the Acadians is that we can actually identify many or most of them, at least at some point in time. As my cousin, Paul LeBlanc, once said, if you’re related to one Acadian, you’re related to all Acadians. Then he proceeded to tell me that he and I are related 137 different ways. My head hurts!

It’s no wonder that endogamy is incredibly difficult beyond the first few generations when it turns into something like multi-colored jello soup.

“Are Your Parents Related?” Tool

There’s another tool that you can utilize to determine if your parents are related to each other.

To determine if your parents are related to each other, you need to know about ROH, or Runs of Homozygosity (ROH).

ROH means that the DNA on both strands or copies of the same chromosome is identical.

For a few locations in a row, ROH can easily happen just by chance, but the longer the segment, the less likely that commonality occurs simply by chance.

The good news is that you don’t need to know the identity of either of your parents. You don’t need either of your parent’s DNA tests – just your own. You’ll need to upload your DNA file to GEDmatch, which is free.

Click on “Are your parents related?”

GEDMatch analyzes your DNA to see if any of your DNA, above a reasonable matching threshold, is identical on both strands, indicating that you inherited the exact same DNA from both of your parents.

A legitimate match, meaning one that’s not by chance, will include many contiguous matching locations, generally a minimum of 500 SNPs or locations in a row. GEDmatch’s minimum threshold for identifying identical ancestral DNA (ROH) is 200 cM.

Here’s my result, including the graphic for the first two chromosomes. Notice the tiny green bars that show identical by chance tiny sliver segments.

I have no significant identical DNA, meaning my parents are not related to each other.

Next, let’s look at an endogamous example where there are small, completely identical segments across a person’s chromosome

This person’s Acadian parents are related to each other, but distantly.

Next, let’s look at a Jewish person’s results.

You’ll notice larger green matching ROH, but not over 200 contiguous SNPs and 7 cM.

GEDMatch reports that this Jewish person’s parents are probably not related within recent generations, but it’s clear that they do share DNA in common.

People whose parents are distantly related have relatively small, scattered matching segments. However, if you’re seeing larger ROH segments that would be large enough to match in a genealogical setting, meaning multiple greater than 7 cM and 500 SNPs,, you may be dealing with a different type of situation where cousins have married in recent generations. The larger the matching segments, generally, the closer in time.

Blogger Kitty Cooper wrote an article, here, about discovering that your parents are related at the first cousin level, and what their GEDMatch “Are Your Parents Related” results look like.

Let’s look for more clues.

Surnames

There MAY be an endogamy clue in the surnames of the people you match.

Viewing surnames is easier if you download your match list, which you can do at every vendor except Ancestry. I’m not referring to the segment data, but the information about your matches themselves.

I provided instructions in the recent article, How to Download Your DNA Match Lists and Segment Files, here.

If you suspect endogamy for any reason, look at your closest matches and see if there is a discernable trend in the surnames, or locations, or any commonality between your matches to each other.

For example, Jewish, Acadian, and Native surnames may be recognizable, as may locations.

You can evaluate in either or both of two ways:

  • The surnames of your closest matches. Closest matches listed first will be your default match order.
  • Your most frequently occurring surnames, minus extremely common names like Smith, Jones, etc., unless they are also in your closest matches. To utilize this type of matching, sort the spreadsheet in surname order and then scan or count the number of people with each surname.

Here are some examples from our testers.

Jewish – Closest surname matches.

  • Roth
  • Weiss
  • Goldman
  • Schonwald
  • Levi
  • Cohen
  • Slavin
  • Goodman
  • Sender
  • Trebatch

Acadian – Closest surname matches.

  • Bergeron
  • Hebert
  • Bergeron
  • Marcum
  • Muise
  • Legere
  • Gaudet
  • Perry
  • Verlander
  • Trombley

Native American – Closest surname matches.

  • Ortega
  • Begay
  • Valentine
  • Hayes
  • Montoya
  • Sun Bear
  • Martin
  • Tsosie
  • Chiquito
  • Yazzie

You may recognize these categories of surnames immediately.

If not, Google is your friend. Eliminate common surnames, then Google for a few together at a time and see what emerges.

The most unusual surnames are likely your best bets.

Projects

Another way to get some idea of what groups people with these surnames might belong to is to enter the surname in the FamilyTreeDNA surname search.

Go to the main FamilyTreeDNA page, but DO NOT sign on.

Scroll down until you see this image.

Type the surname into the search box. You’ll see how many people have tested with that surname, along with projects where project administrators have included that surname indicating that the project may be of interest to at least some people with that surname.

Here’s a portion of the project list for Cohen, a traditional Jewish surname.

These results are for Muise, an Acadian surname.

Clicking through to relevant surname projects, and potentially contacting the volunteer project administrator can go a very long way in helping you gather and sift information. Clearly, they have an interest in this topic.

For example, here’s the Muise surname in the Acadian AmerIndian project. Two great hints here – Acadian heritage and Halifax, Nova Scotia.

Repeat for the balance of surnames on your list to look for commonalities, including locations on the public project pages.

Locations

Some of the vendor match files include location information. Each person on your match list will have the opportunity at the vendor where they tested to include location information in a variety of ways, either for their ancestors or themselves.

Where possible, it’s easiest to sort or scan the download file for this type of information.

Ancestry does not provide or facilitate a match list, but you can still create your own for your closest 20 or 30 matches in a spreadsheet.

MyHeritage provides common surname and ancestral location information for every match. How cool is that!

Y DNA, Mitochondrial DNA, and Endogamy

Haplogroups for both Y and mitochondrial DNA can indicate and sometimes confirm endogamy. In other cases, the haplogroup won’t help, but the matches and their location information just might.

FamilyTreeDNA is the only vendor that provides Y DNA and mitochondrial DNA tests that include highly granular haplogroups along with matches and additional tools.

23andMe provides high-level haplogroups which may or may not be adequate to pinpoint a haplogroup that indicates endogamy.

Of course, only males carry Y DNA that tracks to the direct paternal (surname) line, but everyone carries their mother’s mitochondrial DNA that represents their mother’s mother’s mother’s, or direct matrilineal line.

Some haplogroups are known to be closely associated with particular ethnicities or populations, like Native Americans, Pacific Islanders, and some Jewish people.

Haplogroups reach back in time before genealogy and can give us a sense of community that’s not available by either looking in the mirror or through traditional records.

This Native American man is a member of high-level haplogroup Q-M242. However, some men who carry this haplogroup are not Native, but are of European or Middle Eastern origin.

I entered the haplogroup in the FamilyTreeDNA Discover tool, which I wrote about, here.

Checking the information about this haplogroup reveals that their common ancestor descended from an Asian man about 30,000 years ago.

The migration path in the Americans explains why this person would have an endogamous heritage.

Our tester would receive a much more refined haplogroup if he upgraded to the Big Y test at FamilyTreeDNA, which would remove all doubt.

However, even without additional testing, information about his matches at FamilyTreeDNA may be very illuminating.

The Q-M242 Native man’s Y DNA matches men with more granular haplogroups, shown above, at left. On the Haplogroup Origins report, you can see that these people have all selected the “US (Native American)” country option.

Another useful tool would be to check the public Y haplotree, here, and the public mitochondrial tree here, for self-reported ancestor location information for a specific haplogroup.

Here’s an example of mitochondrial haplogroup A2 and a few subclades on the public mitochondrial tree. You can see that the haplogroup is found in Mexico, the US (Native,) Canada, and many additional Caribbean, South, and Central American countries.

Of course, Y DNA and mitochondrial DNA (mtDNA) tell a laser-focused story of one specific line, each. The great news, if you’re seeking information about your mother or father, the Y is your father’s direct paternal (surname) line, and mitochondrial is your mother’s direct matrilineal line.

Y and mitochondrial DNA results combined with ethnicity, autosomal matching, and the wide range of other tools that open doors, you will be able to reveal a great deal of information about whether you have endogamous heritage or not – and if so, from where.

I’ve provided a resource for stepping through and interpreting your Y DNA results, here, and mitochondrial DNA, here.

Discover for Y DNA Only

If you’re a female, you may feel left out of Y DNA testing and what it can tell you about your heritage. However, there’s a back door.

You can utilize the Y DNA haplogroups of your closest autosomal matches at both FamilyTreeDNA and 23andMe to reveal information

Haplogroup information is available in the download files for both vendors, in addition to the Family Finder table view, below, at FamilyTreeDNA, or on your individual matches profile cards at both 23andMe and FamilyTreeDNA.

You can enter any Y DNA haplogroup in the FamilyTreeDNA Discover tool, here.

You’ll be treated to:

  • Your Haplogroup Story – how many testers have this haplogroup (so far), where the haplogroup is from, and the haplogroup’s age. In this case, the haplogroup was born in the Netherlands about 250 years ago, give or take 200 years. I know that it was 1806 or earlier based on the common ancestor of the men who tested.
  • Country Frequency – heat map of where the haplogroup is found in the world.
  • Notable Connections – famous and infamous (this haplogroup’s closest notable person is Leo Tolstoy).
  • Migration Map – migration path out of Africa and through the rest of the world.
  • Ancient Connections – ancient burials. His closest ancient match is from about 1000 years ago in Ukraine. Their shared ancestor lived about 2000 years ago.
  • Suggested Projects – based on the surname, projects that other matches have joined, and haplogroups.
  • Scientific Details – age estimates, confidence intervals, graphs, and the mutations that define this haplogroup.

I wrote about the Discover tool in the article, FamilyTreeDNA DISCOVER Launches – Including Y DNA Haplogroup Ages.

Endogamy Tools Summary Tables

Endogamy is a tough nut sometimes, especially if you’re starting from scratch. In order to make this topic a bit easier and to create a reference tool for you, I’ve created three summary tables.

  • Various endogamy-related tools available at each vendor which will or may assist with evaluating endogamy
  • Tools and their ability to detect endogamy in different groups
  • Tools best suited to assist people seeking information about unknown parents or grandparents

Summary of Endogamy Tools by Vendor

Please note that GEDMatch is not a DNA testing vendor, but they accept uploads and do have some tools that the testing vendors do not.

Summary of Endogamous Populations Identified by Each Tool

The following chart provides a guideline for which tools are useful for the following types of endogamous groups. Bolded tools require that both parents be descended from the same endogamous group, but several other tools give more definitive results with higher amounts of endogamy.

Y and mitochondrial DNA testing are not affected by admixture, autosomal DNA or anything from the “other” parent.

Tool Jewish Acadian Anabaptist Native Other/General
Ethnicity Yes No No Yes Pacific Islander
Ethnicity Painting Yes No No Yes Pacific Islander
Ethnicity Phasing Yes, if different No No Yes, if different Pacific Islander, if different
DNA Communities Yes Possibly Possibly Yes Pacific Islander

Summary of Endogamy Tools to Assist People Seeking Unknown Parents and Grandparents

This table provides a summary of when each of the various tools can be useful to:

  • People seeking unknown close relatives
  • People who already know who their close relatives are, but are seeking additional information or clues about their genealogy

I considered rating these on a 1 to 10 scale, but the relative usefulness of these tools is dependent on many factors, so different tools will be more or less useful to different people.

For example, ethnicity is very useful if someone is admixed from different populations, or even 100% of a specific endogamous population. It’s less useful if the tester is 100% European, regardless of whether they are seeking close relatives or not. Conversely, even “vanilla” ethnicity can be used to rule out majority or recent admixture with many populations.

Tools Unknown Close Relative Seekers Known Close Relatives – Enhance Genealogy
Ethnicity Yes, to identify or rule out populations Yes
Ethnicity Painting Yes, possibly, depending on population Yes, possibly, depending on population
Ethnicity Phasing Yes, possibly, depending on population Yes, possibly, depending on population
DNA Communities Yes, possibly, depending on population Yes, possibly, depending on population
Genetic Groups Possibly, depending on population Possibly, depending on population
Family Matching aka Bucketing Not if parents are entirely unknown, but yes if one parent is known Yes
Chromosome Browser Unlikely Yes
AutoClusters Yes Yes, especially at MyHeritage if Jewish
Estimated Relationships High Not No
Relationship Range High Not reliably No
More, Smaller Segments Unlikely Unlikely other than confirmation
Match List Download Yes Yes

FamilyTreeDNA DISCOVER™ Launches – Including Y DNA Haplogroup Ages

FamilyTreeDNA just released an amazing new group of public Y DNA tools.

Yes, a group of tools – not just one.

The new Discover tools, which you can access here, aren’t just for people who have tested at FamilyTreeDNA . You don’t need an account and it’s free for everyone. All you need is a Y DNA haplogroup – from any source.

I’m going to introduce each tool briefly because you’re going to want to run right over and try Discover for yourself. In fact, you might follow along with this article.

Y DNA Haplogroup Aging

The new Discover page provides seven beta tools, including Y DNA haplogroup aging.

Haplogroup aging is THE single most requested feature – and it’s here!

Discover also scales for mobile devices.

Free Beta Tool

Beta means that FamilyTreeDNA is seeking your feedback to determine which of these tools will be incorporated into their regular product, so expect a survey.

If you’d like changes or something additional, please let FamilyTreeDNA know via the survey, their support line, email or Chat function.

OK, let’s get started!

Enter Your Haplogroup

Enter your Y DNA haplogroup, or the haplogroup you’re interested in viewing.

If you’re a male who has tested with FamilyTreeDNA , sign on to your home page and locate your haplogroup badge at the lower right corner.

If you’re a female, you may be able to test a male relative or find a haplogroup relevant to your genealogy by visiting your surname group project page to locate the haplogroup for your ancestor.

I’ll use one of my genealogy lines as an example.

In this case, several Y DNA testers appear under my ancestor, James Crumley, in the Crumley DNA project.

Within this group of testers, we have two different Big Y haplogroups, and several estimated haplogroups from testers who have not upgraded to the Big Y.

If you’re a male who has tested at either 23andMe or LivingDNA, you can enter your Y DNA haplogroup from that source as well. Those vendors provide high-level haplogroups.

The great thing about the new Discover tool is that no matter what haplogroup you enter, there’s something for you to enjoy.

I’m going to use haplogroup I-FT272214, the haplogroup of my ancestor, James Crumley, confirmed through multiple descendants. His son John’s descendants carry haplogroup I-BY165368 in addition to I-FT272214, which is why there are two detailed haplogroups displayed for this grouping within the Crumley haplogroup project, in addition to the less-refined I-M223.

Getting Started

When you click on Discover, you’ll be asked to register briefly, agree to terms, and provide your email address.

Click “View my report” and your haplogroup report will appear.

Y DNA Haplogroup Report

For any haplogroup you enter, you’ll receive a haplogroup report that includes 7 separate pages, shown by tabs at the top of your report.

Click any image to enlarge

The first page you’ll see is the Haplogroup Report.

On the first page, you’ll find Haplogroup aging. The TMRCA (time to most recent common ancestor) is provided, plus more!

The report says that haplogroup I-FT272214 was “born,” meaning the mutation that defines this haplogroup, occurred about 300 years ago, plus or minus 150 years.

James Crumley was born about 1710. We know his sons carry haplogroup I-FT272214, but we don’t know when that mutation occurred because we don’t have upstream testers. We don’t know who his parents were.

Three hundred years before the birth of our Crumley tester would be about 1670, so roughly James Crumley’s father’s generation, which makes sense.

James’ son John’s descendants have an additional mutation, so that makes sense too. SNP mutations are known to occur approximately every 80 years, on average. Of course, you know what average means…may not fit any specific situation exactly.

The next upstream haplogroup is I-BY100549 which occurred roughly 500 years ago, plus or minus 150 years. (Hint – if you want to view a haplogroup report for this upstream haplogroup, just click on the haplogroup name.)

There are 5 SNP confirmed descendants of haplogroup I-FT272214 claiming origins in England, all of whom are in the Crumley DNA project.

Haplogroup descendants mean this haplogroup and any other haplogroups formed on the tree beneath this haplogroup.

Share

If you scroll down a bit, you can see the share button on each page. If you think this is fun, you can share through a variety of social media resources, email, or copy the link.

Sharing is a good way to get family members and others interested in both genealogy and genetic genealogy. Light the spark!

I’m going to be sharing with collaborative family genealogy groups on Facebook and Twitter. I can also share with people who may not be genealogists, but who will think these findings are interesting.

If you keep scrolling under the share button or click on “Discover More” you can order Y DNA tests if you’re a biological male and haven’t already taken one. The more refined your haplogroup, the more relevant your information will be on the Discover page as well as on your personal page.

Scrolling even further down provides information about methods and sources.

Country Frequency

The next tab is Country Frequency showing the locations where testers with this haplogroup indicate that their earliest known ancestors are found.

The Crumley haplogroup has only 5 people, which is less than 1% of the people with ancestors from England.

However, taking a look at haplogroup R-M222 with many more testers, we see something a bit different.

Ireland is where R-M222 is found most frequently. 17% of the men who report their ancestors are from Ireland belong to haplogroup R-M222.

Note that this percentage also includes haplogroups downstream of haplogroup R-M222.

Mousing over any other location provides that same information for that area as well.

Seeing where the ancestors of your haplogroup matches are from can be extremely informative. The more refined your haplogroup, the more useful these tools will be for you. Big Y testers will benefit the most.

Notable Connections

On the next page, you’ll discover which notable people have haplogroups either close to you…or maybe quite distant.

Your first Notable Connection will be the one closest to your haplogroup that FamilyTreeDNA was able to identify in their database. In some cases, the individual has tested, but in many cases, descendants of a common ancestor tested.

In this case, Bill Gates is our closest notable person. Our common haplogroup, meaning the intersection of Bill Gates’s haplogroup and my Crumley cousin’s haplogroup is I-L1195. The SNP mutation that defines haplogroup I-L1145 occurred about 4600 years ago. Both my Crumley cousin and Bill Gates descend from that man.

If you’re curious and want to learn more about your common haplogroup, remember, you can enter that haplogroup into the Discover tool. Kind of like genetic time travel. But let’s finish this one first.

Remember that CE means current era, or the number of years since the year “zero,” which doesn’t technically exist but functions as the beginning of the current era. Bill Gates was born in 1955 CE

BCE means “before current era,” meaning the number of years before the year “zero.” So 2600 BCE is approximately 4600 years ago.

Click through each dot for a fun look at who you’re “related to” and how distantly.

This tool is just for fun and reinforces the fact that at some level, we’re all related to each other.

Maybe you’re aware of more notables that could be added to the Discover pages.

Migration Map

The next tab provides brand spanking new migration maps that show the exodus of the various haplogroups out of Africa, through the Middle East, and in this case, into Europe.

Additionally, the little shovel icons show the ancient DNA sites that date to the haplogroup age for the haplogroup shown on the map, or younger. In our case, that’s haplogroup I-M223 (red arrow) that was formed about 16,000 years ago in Europe, near the red circle, at left. These haplogroup ancient sites (shovels) would all date to 16,000 years ago or younger, meaning they lived between 16,000 years ago and now.

Click to enlarge

By clicking on a shovel icon, more information is provided. It’s very interesting that I-L1145, the common haplogroup with Bill Gates is found in ancient DNA in Cardiff, Wales.

This is getting VERY interesting. Let’s look at the rest of the Ancient Connections.

Ancient Connections

Our closest Ancient Connection in time is Gen Scot 24 (so name in an academic paper) who lived in the Western Isles of Scotland.

These ancient connections are more likely cousins than direct ancestors, but of course, we can’t say for sure. We do know that the first man to develop haplogroup I-L126, about 2500 years ago, is an ancestor to both Gen Scot 24 and our Crumley ancestor.

Gen Scot 24 has been dated to 1445-1268 BCE which is about 3400 years ago, which could actually be older than the haplogroup age. Remember that both dating types are ranges, carbon dating is not 100% accurate, and ancient DNA can be difficult to sequence. Haplogroup ages are refined as more branches are discovered and the tree grows.

The convergence of these different technologies in a way that allows us to view the past in the context of our ancestors is truly amazing.

All of our Crumley cousin’s ancient relatives are found in Ireland or Scotland with the exception of the one found in Wales. I think, between this information and the haplogroup formation dates, it’s safe to say that our Crumley ancestors have been in either Scotland or Ireland for the past 4600 years, at least. And someone took a side trip to Wales, probably settled and died there.

Of course, now I need to research what was happening in Ireland and Scotland 4600 years ago because I know my ancestors were involved.

Suggested Projects

I’m EXTREMELY pleased to see suggested projects for this haplogroup based on which projects haplogroup members have joined.

You can click on any of the panels to read more about the project. Remember that not everyone joins a project because of their Y DNA line. Many projects accept people who are autosomally related or descend from the family through the mitochondrial line, the direct mother’s line.

Still, seeing the Crumley surname project would be a great “hint” all by itself if I didn’t already have that information.

Scientific Details

The Scientific Details page actually has three tabs.

The first tab is Age Estimate.

The Age Estimate tab provides more information about the haplogroup age or TMRCA (Time to Most Recent Common Ancestor) calculations. For haplogroup I-FT272214, the most likely creation date, meaning when the SNP occurred, is about 1709, which just happens to align well with the birth of James Crumley about 1710.

However, anyplace in the dark blue band would fall within a 68% confidence interval (CI). That would put the most likely years that the haplogroup-defining SNP mutation took place between 1634 and 1773. At the lower end of the frequency spectrum, there’s a 99% likelihood that the common ancestor was born between 1451 and 1874. That means we’re 99% certain that the haplogroup defining SNP occurred between those dates. The broader the date range, the more certain we can be that the results fall into that range.

The next page, Variants, provides the “normal” or ancestral variant and the derived or mutated variant or SNP (Single Nucleotide Polymorphism) in the position that defines haplogroup I-FT272214.

The third tab displays FamilyTreeDNA‘s public Y DNA Tree with this haplogroup highlighted. On the tree, we can see this haplogroup, downstream haplogroups as well as upstream, along with their country flags.

Your Personal Page

If you have already taken a DNA test at FamilyTreeDNA, you can find the new Discover tool conveniently located under “Additional Tests and Tools.”

If you are a male and haven’t yet tested, then you’ll want to order a Y DNA test or upgrade to the Big Y for the most refined haplogroup possible.

Big Y tests and testers are why the Y DNA tree now has more than 50,000 branches and 460,000 variants. Testing fuels growth and growth fuels new tools and possibilities for genealogists.

What Do You Think?

Do you like these tools?

What have you learned? Have you shared this with your family members? What did they have to say? Maybe we can get Uncle Charley interested after all!

Let me know how you’re using these tools and how they are helping you interpret your Y DNA results and assist your genealogy.

I receive a small contribution when you click on some of the links to vendors in my articles. This does NOT increase the price you pay but helps me to keep the lights on and this informational blog free for everyone. Please click on the links in the articles or to the vendors below if you are purchasing products or DNA testing.

Thank you so much.
