Join Me for DNA Day, Live

I’m excited to be presenting for an entire day of DNA on October 1st. You can join in too, because the Orange County Genealogical Society has graciously made this event open to the entire genealogy community via Zoom. You can sign up at this link.

Apparently, there’s some serendipity involved, because the Y, mitochondrial DNA, and X DNA sessions were specifically requested when I asked for RootsTech topic suggestions. You’re not going to have to wait nearly that long, because I’m covering all three at DNA Day.

These sessions will:

  • Educate about the topic at hand, meaning Y, mitochondrial DNA, and X DNA, and when to use each.
  • Discuss how to utilize the results from all three of these tests and types of DNA for genealogy, including the new FamilyTreeDNA Y DNA Discover tool. I’m providing step-by-step instructions.
  • Provide real-world analysis examples with case studies. These are always so much fun! I’ve actually made a couple of discoveries while preparing for these sessions.

The last session of the day, “DNA Tossed Salad,” ties everything together. I’ll discuss how I manage the results and the tools I use, particularly for autosomal tests, and what I “do” with matches.

Each session will have the opportunity for Q&A.

I’ve included information for every level, beginner through advanced. Here’s the registration link again. Hope to see you on October 1st!!!

DNA: In Search of…Full and Half-Siblings

This is the fifth article 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 identify ancestors further back in time as well.

Please note that if a family member has tested and you do NOT see their results, ask them to verify that they have chosen to allow matching and for other people to view them in their match list. That process varies at different vendors.

You can also ask if they can see you in their results.

All Parties Need to Test

Searching for unknown siblings isn’t exactly searching, because to find them, they, themselves, or their descendant(s) must have taken a DNA test at the same vendor where you tested or uploaded a DNA file.

You may know through any variety of methods that they exist, or might exist, but if they don’t take a DNA test, you can’t find them using DNA. This might sound obvious, but I see people commenting and not realizing that the other sibling(s) must test too – and they may not have.

My first questions when someone comments in this vein are:

  1. Whether or not they are positive their sibling actually tested, meaning actually sent the test in to the vendor, and it was received by the testing company. You’d be surprised how many tests are living in permanent residence on someone’s countertop until it gets pushed into the drawer and forgotten about.
  2. If the person has confirmed that their sibling has results posted. They may have returned their test, but the results aren’t ready yet or there was a problem.
  3. AND that both people have authorized matching and sharing of results. Don’t hesitate to reach out to your vendor’s customer care if you need help with this.

Sibling Scenarios

The most common sibling scenarios are when one of two things happens:

  • A known sibling tests, only to discover that they don’t match you in the full sibling range, or not at all, when you expected they would
  • You discover a surprise match in the full or half-sibling range

Let’s talk about these scenarios and how to determine:

  • If someone is a sibling
  • If they are a full or half-sibling
  • If a half-sibling, if they descend from your mother or father

As with everything else genetic, we’ll be gathering and analyzing different pieces of evidence along the way.

Full and Half-Siblings

Just to make sure we are all on the same page:

  • A full sibling is someone who shares both parents with you.
  • A half-sibling is someone who shares one parent with you, but not the other parent.
  • A step-sibling is someone who shares no biological parents with you. This situation occurs when your parent marries their parent, after you are both born, and their parent becomes your step-parent. You share neither of your biological parents with a step-sibling, so you share no DNA and will not show up on each other’s match lists.
  • A three-quarters sibling is someone with whom you share one parent, but two siblings are the other parent. For example, you share the same mother, but one brother fathered you, and your father’s brother fathered your sibling. Yes, this can get very messy and is almost impossible for a non-professional to sort through, if even then. (This is not a solicitation. I do not take private clients.) We will not be addressing this situation specifically.

Caution

With any search for unknown relatives, you have no way of knowing what you will find.

In one’s mind, there are happy reunions, but you may experience something entirely different. Humans are human. Their stories are not always happy or rosy. They may have made mistakes they regret. Or they may have no regrets about anything.

Your sibling may not know about you or the situation under which you, or they, were born. Some women were victims of assault and violence, which is both humiliating and embarrassing. I wrote about difficult situations, here.

Your sibling or close family member may not be receptive to either you, your message, or even your existence. Just be prepared, because the seeking journey may not be pain-free for you or others, and may not culminate with or include happy reunions.

On the other hand, it may.

Please step back and ponder a bit about the journey you are about to undertake and the possible people that may be affected, and how. This box, once opened, cannot be closed again. Be sure you are prepared.

On the other hand, sometimes that box lid pops off, and the information simply falls in your lap one day when you open your match list, and you find yourself sitting there, in shock, staring at a match, trying to figure out what it all means.

Congratulations, You Have a Sibling!

This might not be exactly what runs through your mind when you see that you have a very close match that you weren’t expecting.

The first two things I recommend when making this sort of discovery, after a few deep breaths, a walk, and a cup of tea, are:

  • Viewing what the vendor says
  • Using the DNAPainter Shared cM Relationship Chart

Let’s start with DNAPainter.

DNAPainter

DNAPainter provides a relationship chart, here, based on the values from the Shared cM Project.

You can either enter a cM amount or a percentage of shared DNA. I prefer the cM amount, but it doesn’t really matter.

I’ll enter 2241 cM from a known half-sibling match. To enter a percent, click on the green “enter %.”

As you can see, statistically speaking, this person is slightly more likely to be a half-sibling than they are to be a full sibling. In reality, they could be either.

Looking at the chart below, DNAPainter highlights the possible relationships from the perspective of “Self.”

The average of all the self-reported relationships is shown, on top, so 2613 for a full sibling. The range is shown below, so 1613-3488 for a full sibling.

In this case, there are several possibilities for two people who share 2241 cM of DNA.

I happen to know that these two people are half-siblings, but if I didn’t, it would be impossible to tell from this information alone.

The cM range for full siblings is 1613-3488, and the cM range for half-siblings is 1160-2436.

  • The lower part of the matching range, from 1160-1613 cM is only found in half-siblings.
  • The portion of the range from 1613-2436 cM can be either half or full siblings.
  • The upper part of the range, from 2436-3488 cM is only found in full siblings.

If your results fall into the center portion of the range, you’re going to need to utilize other tools. Fortunately, we have several.

If you’ve discovered something unexpected, you’ll want to verify using these tools, regardless. Use every tool available. Ranges are not foolproof, and the upper and lower 10% of the responses were removed as outliers. You can read more about the shared cM Project, here and here.

Furthermore, people may be reporting some half-sibling relationships as full sibling relationships, because they don’t expect to be half-siblings, so the ranges may be somewhat “off.”

Relationship Probability Calculator

Third-party matching database, GEDmatch, provides a Relationship Probability Calculator tool that is based on statistical probability methods without compiled user input. Both tools are free, and while I haven’t compared every value, both seem to be reasonably accurate, although they do vary somewhat, especially at the outer ends of the ranges.

When dealing with sibling matches, if you are in all four databases, GEDmatch is a secondary resource, but I will include GEDmatch when they have a unique tool as well as in the summary table. Some of your matches may be willing to upload to GEDmatch if the vendor where you match doesn’t provide everything you need and GEDmatch has a supplemental offering.

Next, let’s look at what the vendors say about sibling matches.

Vendors

Each of the major vendors reports sibling relationships in a slightly different way.

Sibling Matches at Ancestry

Ancestry reports sibling relationships as Sister or Brother, but they don’t say half or full.

If you click on the cM portion of the link, you’ll see additional detail, below

Ancestry tells you that the possible relationships are 100% “Sibling.” The only way to discern the difference between full and half is by what’s next.

If the ONLY relationship shown is Sibling at 100%, that can be interpreted to mean this person is a full sibling, and that a half-sibling or other relationship is NOT a possibility.

Ancestry never stipulates full or half.

The following relationship is a half-sibling at Ancestry.

Ancestry identifies that possible range of relationships as “Close Family to First Cousin” because of the overlaps we saw in the DNAPainter chart.

Clicking through shows that there is a range of possible relationships, and Ancestry is 100% sure the relationship is one of those.

DNAPainter agrees with Ancestry except includes the full-sibling relationship as a possibility for 1826 cM.

Sibling Matches at 23andMe

23andMe does identify full versus half-siblings.

DNAPainter disagrees with 23andMe and claims that anyone who shares 46.2% of their DNA is a parent/child.

However, look at the fine print. 23andMe counts differently than any of the other vendors, and DNAPainter relies on the Shared cM Project, which relies on testers entering known relationship matching information. Therefore, at any other vendor, DNAPainter is probably exactly right.

Before we understand how 23andMe counts, we need to understand about half versus fully identical segments.

To determine half or full siblings, 23andMe compares two things:

  1. The amount of shared matching DNA between two people
  2. Fully Identical Regions (FIR) of DNA compared to Half Identical Regions (HIR) of DNA to determine if any of your DNA is fully identical, meaning some pieces of you and your sibling’s DNA is exactly the same on both your maternal and paternal chromosomes.

Here’s an example on any chromosome – I’ve randomly selected chromosome 12. Which chromosome doesn’t matter, except for the X, which is different.

Your match isn’t broken out by maternal and paternal sides. You would simply see, on the chromosome browser, that you and your sibling match at these locations, above.

In reality, though, you have two copies of each chromosome, one from Mom and one from Dad, and so does your sibling.

In this example, Mom’s chromosome is visualized on top, and Dad’s is on the bottom, below, but as a tester, you don’t know that. All you know is that you match your sibling on all of those blue areas, above.

However, what’s actually happening in this example is that you are matching your sibling on parts of your mother’s chromosome and parts of your father’s chromosome, shown above as green areas

23andMe looks at both copies of your chromosome, the one you inherited from Mom, on top, and Dad, on the bottom, to see if you match your sibling on BOTH your mother’s and your father’s chromosomes in that location.

I’ve boxed the green matching areas in purple where you match your sibling fully, on both parents’ chromosomes.

If you and your sibling share both parents, you will share significant amounts of the same DNA on both copies of the same chromosomes, meaning maternal and paternal. In other words, full siblings share some purple fully identical regions (FIR) of DNA with each other, while half-siblings do not (unless they are also otherwise related) because half-siblings only share one parent with each other. Their DNA can’t be fully identical because they have a different parent that contributed the other copy of their chromosome.

Total Shared DNA Fully Identical DNA from Both Parents
Full Siblings ~50% ~25%
Half Siblings ~25% 0
  • Full siblings are expected to share about 50% of the same DNA. In other words, their DNA will match at that location. That’s all the green boxed locations, above.
  • Full siblings are expected to share about 25% of the same DNA from BOTH parents at the same location on BOTH copies of their chromosomes. These are fully identical regions and are boxed in purple, above.

You’ll find fully identical segments about 25% of the time in full siblings, but you won’t find fully identical segments in half-siblings. Please note that there are exceptions for ¾ siblings and endogamous populations.

You can view each match at 23andMe to see if you have any completely identical regions, shown in dark purple in the top comparison of full siblings. Half siblings are shown in the second example, with less total matching DNA and no FIR or completely identical regions.

Please note that your matching amount of DNA will probably be higher at 23andMe than at other companies because:

  • 23andMe includes the X chromosome in the match totals
  • 23andMe counts fully identical matching regions twice. For full siblings, that’s an additional 25%

Therefore, a full sibling with an X match will have a higher total cM at 23andMe than the same siblings elsewhere because not only is the X added into the total, the FIR match region is added a second time too.

Fully Identical Regions (FIR) and Half Identical Regions (HIR) at GEDmatch

At GEDMatch, you can compare two people to each other, with an option to display the matching information and a painted graphic for each chromosome that includes FIR and HIR.

If you need to know if you and a match share fully identical regions and you haven’t tested at 23andMe, you can both upload your DNA data file to GEDmatch and use their One to One Autosomal DNA Comparison.

On the following page, simply enter both kit numbers and accept the defaults, making sure you have selected one of the graphics options.

While GEDmatch doesn’t specifically tell you whether someone is a full or half sibling, you can garner additional information about the relationship based on the graphic at GEDmatch.

GEDMatch shows both half and fully identical regions.

The above match is between two full siblings using a 7 cM threshold. The blue on the bottom bar indicates a match of 7 cM or larger. Black means no match.

The green regions in the top bar indicate places where these two people carry the same DNA on both copies of their chromosome 1. This means that both people inherited the same DNA from BOTH parents on the green segments.

In the yellow regions, the siblings inherited the same DNA from ONE parent, but different DNA in that region from the other parent. They do match each other, just on one of their chromosomes, not both.

Without a tool like this to differentiate between HIR and FIR, you can’t tell if you’re matching someone on one copy of your chromosome, or on both copies.

In the areas marked with red on top, which corresponds to the black on the bottom band, these two siblings don’t match each other because they inherited different DNA from both parents in that region. The yellow in that region is too scattered to be significant.

Full siblings generally share a significant amount of FIR, or fully identical regions of DNA – about 25%.

Half siblings will share NO significant amount of FIR, although some will be FIR on very small, scattered green segments simply by chance, as you can see in the example, below.

This half-sibling match shares no segments large enough to be a match (7 cM) in the black section. In the blue matching section, only a few small green fragments of DNA match fully, which, based on the rest of that matching segment, must be identical by chance or misreads. There are no significant contiguous segments of fully identical DNA.

When dealing with full or half-siblings, you’re not interested in small, scattered segments of fully identical regions, like those green snippets on chromosome 6, but in large contiguous sections of matching DNA like the chromosome 1 example.

GEDmatch can help when you match when a vendor does not provide FIR/HIR information, and you need additional assistance.

Next, let’s look at full and half-siblings at FamilyTreeDNA

Sibling Matches at FamilyTreeDNA

FamilyTreeDNA does identify full siblings.

Relationships other than full siblings are indicated by a range. The two individuals below are both half-sibling matches to the tester.

The full range when mousing over the relationship ranges is shown below.

DNAPainter agrees except also gives full siblings as an option for the two half-siblings.

FamilyTreeDNA also tells you if you have an X match and the size of your X match.

We will talk about X matching in a minute, which, when dealing with sibling identification, can turn out to be very important.

Sibling Matches at MyHeritage

MyHeritage indicates brother or sister for full siblings

MyHeritage provides other “Estimated relationships” for matches too small to be full siblings.

DNAPainter’s chart agrees with this classification, except adds additional relationship possibilities.

Be sure to review all of the information provided by each vendor for close relationships.

View Close Known Relationships

The next easiest step to take is to compare your full or half-sibling match to known close family members from your maternal and paternal sides, respectively. The closer the family members, the better.

It’s often not possible to determine if someone is a half sibling or a full sibling by centiMorgans (cMs) alone, especially if you’re searching for unknown family members.

Let’s start with the simplest situation first.

Let’s say both of your parents have tested, and of course, you match both of them as parents.

Your new “very close match” is in the sibling range.

The first thing to do at each vendor is to utilize that vendor’s shared matches tool and see whether your new match matches one parent, or both.

Here’s an example.

Close Relationships at FamilyTreeDNA

This person has a full sibling match, but let’s say they don’t know who this is and wants to see if their new sibling matches one or both of their parents.

Select the match by checking the box to the left of the match name, then click on the little two-person icon at far right, which shows “In Common” matches

You can see on the resulting shared match list that both of the tester’s parents are shown on the shared match list.

Now let’s make this a little more difficult.

No Parents, No Problem

Let’s say neither of your parents has tested.

If you know who your family is and can identify your matches, you can see if the sibling you match matches other close relatives on both or either side of your family.

You’ll want to view shared matches with your closest known match on both sides of your tree, beginning with the closest first. Aunts, uncles, first cousins, etc.

You will match all of your family members through second cousins, and 90% of your third cousins. You can view additional relationship percentages in the article, How Much of Them is in You?.

I recommend, for this matching purpose, to utilize 2nd cousins and closer. That way you know for sure if you don’t share them as a match with your sibling, it’s because the sibling is not related on that side of the family, not because they simply don’t share any DNA due to their distance.

In this example, you have three sibling matches. Based on your and their matches to the same known first and second cousins, you can see that:

  • Sibling 1 is your full sibling, because you both match the same maternal and paternal first and second cousins
  • Sibling 2 is your paternal half-sibling because you both match paternal second cousins and closer, but not maternal cousins.
  • Sibling 3 is your maternal half-sibling because you both match maternal second cousins and closer, but not paternal cousins.

Close Relationships at Ancestry

Neither of my parents have tested, but my first cousin on my mother’s side has. Let’s say I have a suspected sibling or half-sibling match, so I click on the match’s name, then on Shared Matches.

Sure enough, my new match also matches my first cousin that I’ve labeled as “on my mother’s side.”

If my new match in the sibling range also matches my second cousins or closer on my father’s side, the new match is a full sibling, not a half-sibling.

Close Relationships at MyHeritage

Comparing my closest match provided a real surprise. I wonder if I’ve found a half-sibling to my mother.

Now, THIS is interesting.

Hmmm. More research is needed, beginning with the age of my match. MyHeritage provides ages if the MyHeritage member authorizes that information to be shared.

Close Relationships at 23andMe

Under DNA Relatives, click on your suspected sibling match, then scroll down and select “Find Relatives in Common.”

The Relatives in Common list shows people that match both of you.

The first common match is very close and a similar relationship to my closest match on my father’s side. This would be expected of a sibling. I have no common matches with this match to anyone on my mother’s side, so they are only related on my father’s side. Therefore they are a paternal half-sibling, not a full sibling.

More Tools Are Available

Hopefully, by now, you’ve been able to determine if your mystery match is a sibling, and if so, if they are a half or full sibling, and through which parent.

We have some additional tools that are relevant and can be very informative in some circumstances. I suggest utilizing these tools, even if you think you know the answer.

In this type of situation, there’s no such thing as too much information.

X Matching

X matching, or lack thereof, may help you determine how you are related to someone.

There are two types of autosomal DNA. The X chromosome versus chromosomes 1-22. The X chromosome (number 23) has a unique inheritance path that distinguishes it from your other chromosomes.

The X chromosome inheritance path also differs between men and women.

Here’s my pedigree chart in fan form, highlighting the ancestors who may have contributed a portion of their X chromosome to me. In the closest generation, this shows that I inherited an X chromosome from both of my parents, and who in each of their lines could have contributed an X to them.

The white or uncolored positions, meaning ancestors, cannot contribute any portion of an X chromosome to me based on how the X chromosome is inherited.

You’ll notice that my father inherited none of his X chromosome from any of his paternal ancestors, so of course, I can’t inherit what he didn’t inherit. There are a very limited number of ancestors on my father’s side whom I can inherit any portion of an X chromosome from.

Men receive their Y chromosome from their fathers, so men ONLY receive an X chromosome from their mother.

Therefore, men MUST pass their mother’s X chromosome on to their female offspring because they don’t have any other copy of the X chromosome to pass on.

Men pass no X chromosome to sons.

We don’t need to worry about a full fan chart when dealing with siblings and half-siblings.

We only need to be concerned with the testers plus one generation (parents) when utilizing the X chromosome in sibling situations.

These two female Disney Princesses, above, are full siblings, and both inherited an X chromosome from BOTH their mother and father. However, their father only has one X (red) chromosome to give them, so the two females MUST match on the entire red X chromosome from their father.

Their mother has two X chromosomes, green and black, to contribute – one from each of her parents.

The full siblings, Melody, and Cinderella:

  • May have inherited some portion of the same green and black X chromosomes from their mother, so they are partial matches on their mother’s X chromosome.
  • May have inherited the exact same full X chromosome from their mother (both inherited the entire green or both inherited the entire black), so they match fully on their mother’s X chromosome.
  • May have inherited the opposite X from different maternal grandparents. One inherited the entire green X and one inherited the entire black X, so they don’t match on their mother’s X chromosome.

Now, let’s look at Cinderella, who matches Henry.

This female and male full sibling match can’t share an X chromosome on the father’s side, because the male’s father doesn’t contribute an X chromosome to him. The son, Henry, inherited a Y chromosome instead from his father, which is what made them males.

Therefore, if a male and female match on the X chromosome, it MUST be through HIS mother, but could be through either of her parents. In a sibling situation, an X match between a male and female always indicates the mother.

In the example above, the two people share both of their mother’s X chromosomes, so are definitely (at least) maternally related. They could be full siblings, but we can’t determine that by the X chromosome in this situation, with males.

However, if the male matches the female on HER father’s X chromosome, there a different message, example below.

You can see that the male is related to the female on her father’s side, where she inherited the entire magenta X chromosome. The male inherited a portion of the magenta X chromosome from his mother, so these two people do have an X match. However, he matches on his mother’s side, and she matches on her father’s side, so that’s clearly not the same parent.

  • These people CAN NOT be full siblings because they don’t match on HER mother’s side too, which would also be his mother’s side if they were full siblings.
  • They cannot be maternal half-siblings because their X DNA only matches on her father’s side, but they wouldn’t know that unless she knew which side was which based on share matches.
  • They cannot be paternal half-siblings because he does not have an X chromosome from his father.

They could, however, be uncle/aunt-niece/nephew or first cousins on his mother’s side and her father’s side. (Yes, you’re definitely going to have to read this again if you ever need male-female X matching.)

Now, let’s look at X chromosome matching between two males. It’s a lot less complicated and much more succinct.

Neither male has inherited an X chromosome from their father, so if two males DO match on the X, it MUST be through their mother. In terms of siblings, this would mean they share the same mother.

However, there is one slight twist. In the above example, you can see that the men inherited a different proportion of the green and black X chromosomes from their common mother. However, it is possible that the mother could contribute her entire green X chromosome to one son, Justin in this example, and her entire black X chromosome to Henry.

Therefore, even though Henry and Justin DO share a mother, their X chromosome would NOT match in this scenario. This is rare but does occasionally happen.

Based on the above examples, the X chromosome may be relevant in the identification of full or half siblings based on the sexes of the two people who otherwise match at a level indicating a full or half-sibling relationship.

Here’s a summary chart for sibling X matching.

X Match Female Male
Female Will match on shared father’s full X chromosome, mother’s X is the same rules as chromosomes 1-22 Match through male’s mother, but either of female’s parents. If the X match is not through the female’s mother, they are not full siblings nor maternal half-siblings. They cannot have an X match through the male’s father. They are either full or half-siblings through their mother if they match on both of their mother’s side. If they match on his mother’s side, and her father’s side, they are not siblings but could be otherwise closely related.
Male Match through male’s mother, but either of female’s parents. If the X match is not through the female’s mother, they are not full siblings nor maternal half-siblings. They cannot have an X match through the male’s father. They are either full or half-siblings through their mother if they match on both or their mother’s side. If they match on his mother’s side, and her father’s side, they are not siblings but could be otherwise closely related. Both males are related on their mother’s side – either full or half-siblings.

Here’s the information presented in a different way.

DOES match X summary:

  • If a male DOES match a female on the X, he IS related to her through HIS mother’s side, but could match her on her mother or father’s side. If their match is not through her mother, then they are not full siblings nor maternal half-siblings. They cannot match through his father, so they cannot be paternal half-siblings.
  • If a female DOES match a female on the X, they could be related on either side and could be full or half-siblings.
  • If a male DOES match a male on the X, they ARE both related through their mother. They may also be related on their father’s side, but the X does not inform us of that.

Does NOT match X summary:

  • If a male does NOT match a female on the X, they are NOT related through HIS mother and are neither full siblings nor maternal half-siblings. Since a male does not have an X chromosome from his father, they cannot be paternal half-siblings based on an X match.
  • If a male does NOT match a male, they do NOT share a mother.
  • If a female does NOT match another female on the X, they are NOT full siblings and are NOT half-siblings on their paternal side. Their father only has one X chromosome, and he would have given the same X to both daughters.

Of the four autosomal vendors, only 23andMe and FamilyTreeDNA report X chromosome results and matching, although the other two vendors, MyHeritage and Ancestry, include the X in their DNA download file so you can find X matches with those files at either FamilyTreeDNA or GEDMatch if your match has or will upload their file to either of those vendors. I wrote step-by-step detailed download/upload instructions, here.

X Matching at FamilyTreeDNA

In this example from FamilyTreeDNA, the female tester has discovered two half-sibling matches, both through her father. In the first scenario, she matches a female on the full X chromosome (181 cM). She and her half-sibling MUST share their father’s entire X chromosome because he only had one X, from his mother, to contribute to both of his daughters.

In the second match to a male half-sibling, our female tester shares NO X match because her father did not contribute an X chromosome to his son.

If we didn’t know which parents these half-sibling matches were through, we can infer from the X matching alone that the male is probably NOT through the mother.

Then by comparing shared matches with each sibling, Advanced Matches, or viewing the match Matrix, we can determine if the siblings match each other and are from the same or different sides of the family.

Under Additional Tests and Tools, Advanced Matching, FamilyTreeDNA provides an additional tool that can show only X matches combined with relationships.

Of course, you’ll need to view shared matches to see which people match the mother and/or match the father.

To see who matches each other, you’ll need to use the Matrix tool.

At FamilyTreeDNA, the Matrix, located under Autosomal DNA Results and Tools, allows you to select your matches to see if they also match each other. If you have known half-siblings, or close relatives, this is another way to view relationships.

Here’s an example using my father and two paternal half-siblings. We can see that the half-siblings also match each other, so they are (at least) half-siblings on the paternal side too.

If they also matched my mother, we would be full siblings, of course.

Next, let’s use Y DNA and mitochondrial DNA.

Y DNA and Mitochondrial DNA

In addition to autosomal DNA, we can utilize Y DNA and mitochondrial DNA (mtDNA) in some cases to identify siblings or to narrow or eliminate relationship possibilities.

Given that Y DNA and mitochondrial DNA both have distinctive inheritance paths, full and half-siblings will, or will not, match under various circumstances.

Y DNA

Y DNA is passed intact from father to son, meaning it’s not admixed with any of the mother’s DNA. Daughters do not inherit Y DNA from their father, so Y DNA is only useful for male-to-male comparisons.

Two types of Y DNA are used for genealogy, STR markers for matching, and haplogroups, and both are equally powerful in slightly different ways.

Y DNA at FamilyTreeDNA

Men can order either 37 or 111 STR marker tests, or the BIg Y which provides more than 700 markers and more. FamilyTreeDNA is the only one of the vendors to offer Y DNA testing that includes STR markers and matching between men.

Men who order these tests will be compared for matching on either 37, 111 or 700 STR markers in addition to SNP markers used for haplogroup identification and assignment.

Fathers will certainly match their sons, and paternal line brothers will match each other, but they will also match people more distantly related.

However, if two men are NOT either full or half siblings on the paternal side, they won’t match at 111 markers.

If two men DON’T match, especially at high marker levels, they likely aren’t siblings. The word “likely” is in there because, very occasionally, a large deletion occurs that prevents STR matching, especially at lower levels.

Additionally, men who take the 37 or 111 marker test also receive an estimated haplogroup at a high level for free, without any additional testing.

However, if men take the Big Y-700 test, they not only will (or won’t) match on up to 700 STR markers, they will also receive a VERY refined haplogroup via SNP marker testing that is often even more sensitive in terms of matching than STR markers. Between these two types of markers, Y DNA testing can place men very granularly in relation to other men.

Men can match in two ways on Y DNA, and the results are very enlightening.

If two men match on BOTH their most refined haplogroup (Big Y test) AND STR markers, they could certainly be siblings or father/son. They could also be related on the same line for another reason, such as known or unknown cousins or closer relationships like uncle/nephew. Of course, Y DNA, in addition to autosomal matching, is a powerful combination.

Conversely, if two men don’t have a similar or close haplogroup, they are not a father and son or paternal line siblings.

FamilyTreeDNA offers both inexpensive entry-level testing (37 and 111 markers) and highly refined advanced testing of most of the Y chromosome (Big Y-700), so haplogroup assignments can vary widely based on the test you take. This makes haplogroup matching and interpretation a bit more complex.

For example, haplogroups R-M269 and I-BY14000 are not related in thousands of years. One is haplogroup R, and one is haplogroup I – completely different branches of the Y DNA tree. These two men won’t match on STR markers or their haplogroup.

However, because FamilyTreeDNA provides over 50,000 different haplogroups, or tree branches, for Big Y testers, and they provide VERY granular matching, two father/son or sibling males who have BOTH tested at the Big Y-700 level will have either the exact same haplogroup, or at most, one branch difference on the tree if a mutation occurred between father and son.

If both men have NOT tested at the Big Y-700 level, their haplogroups will be on the same branch. For example, a man who has only taken a 37/111 marker STR test may be estimated at R-M269, which is certainly accurate as far as it goes.

His sibling who has taken a Big Y test will be many branches further downstream on the tree – but on the same large haplogroup R-M269 branch. It’s essential to pay attention to which tests a Y DNA match has taken when analyzing the match.

The beauty of the two kinds of tests is that even if one haplogroup is very general due to no Big Y test, their STR markers should still match. It’s just that sometimes this means that one hand is tied behind your back.

Y DNA matching alone can eliminate the possibility of a direct paternal line connection, but it cannot prove siblingship or paternity alone – not without additional information.

The Advanced Matching tool will provide a list of matches in all categories selected – in this case, both the 111 markers and the Family Finder test. You can see that one of these men is the father of the tester, and one is the full sibling.

You can view haplogroup assignments on the public Y DNA tree, here. I wrote about using the public tree, here.

In addition, recently, FamilyTreeDNA launched the new Y DNA Discover tool, which explains more about haplogroups, including their ages and other fun facts like migration paths along with notable and ancient connections. I wrote about using the Discover tool, here.

Y DNA at 23andMe

Testers receive a base haplogroup with their autosomal test. 23andMe tests a limited number of Y DNA SNP locations, but they don’t test many, and they don’t test STR markers, so there is no Y DNA matching and no refined haplogroups.

You can view the haplogroups of your matches. If your male sibling match does NOT share the same haplogroup, the two men are not paternal line siblings. If two men DO share the same haplogroup, they MIGHT be paternal siblings. They also might not.

Again, autosomal close matching plus haplogroup comparisons include or exclude paternal side siblings for males.

Paternal side siblings at 23andMe share the same haplogroup, but so do many other people. These two men could be siblings. The haplogroups don’t exclude that possibility. If the haplogroups were different, that would exclude being either full or paternal half-siblings.

Men can also compare their mitochondrial DNA to eliminate a maternal relationship.

These men are not full siblings or maternal half-siblings. We know, unquestionably, because their mitochondrial haplogroups don’t match.

23andMe also constructs a genetic tree, but often struggles with close relative placement, especially when half-relationships are involved. I do not recommend relying on the genetic tree in this circumstance.

Mitochondrial DNA

Mitochondrial DNA is passed from mothers to all of their children, but only females pass it on. If two people, males or females, don’t match on their mitochondrial DNA test, with a couple of possible exceptions, they are NOT full siblings, and they are NOT maternal half-siblings.

Mitochondrial DNA at 23andMe

23andMe provides limited, base mitochondrial haplogroups, but no matching. If two people don’t have the same haplogroup at 23andMe, they aren’t full or maternal siblings, as illustrated above.

Mitochondrial DNA at FamilyTreeDNA

FamilyTreeDNA provides both mitochondrial matching AND a much more refined haplogroup. The full sequence test (mtFull), the only version sold today, is essential for reliable comparisons.

Full siblings or maternal half-siblings will always share the same haplogroup, regardless of their sex.

Generally, a full sibling or maternal half-sibling match will match exactly at the full mitochondrial sequence (FMS) level with a genetic distance of zero, meaning fully matching and no mismatching mutations.

There are rare instances where maternal siblings or even mothers and children do not match exactly, meaning they have a genetic distance of greater than 0, because of a mutation called a heteroplasmy.

I wrote about heteroplasmies, here.

Like Y DNA, mitochondrial DNA cannot identify a sibling or parental relationship without additional evidence, but it can exclude one, and it can also provide much-needed evidence in conjunction with autosomal matching. The great news is that unlike Y DNA, everyone has mitochondrial DNA and it comes directly from their mother.

Once again, FamilyTreeDNA’s Advanced Matching tool provides a list of people who match you on both your mitochondrial DNA test and the Family Finder autosomal test, including transfers/uploads, and provides a relationship.

You can see that our tester matches both a full sibling and their mother. Of course, a parent/child match could mean that our tester is a female and one of her children, of either sex, has tested.

Below is an example of a parent-child match that has experienced a heteroplasmy.

Based on the comparison of both the mitochondrial DNA test, plus the autosomal Family Finder test, you can verify that this is a close family relationship.

You can also eliminate potential relationships based on the mitochondrial DNA inheritance path. The mitochondrial DNA of full siblings and maternal half-siblings will always match at the full sequence and haplogroup level, and paternal half-siblings will never match. If paternal half-siblings do match, it’s happenstance or because of a different reason.

Sibling Summary and Checklist

I’ve created a quick reference checklist for you to use when attempting to determine whether or not a match is a sibling, and, if so, whether they are half or full siblings. Of course, these tools are in addition to the DNAPainter Shared cM Tool and GEDmatch’s Relationship Predictor Calculator.

FamilyTreeDNA Ancestry 23andMe MyHeritage GEDmatch
Matching Yes Yes Yes Yes Yes
Shared Matches Yes – In Common With Yes – Shared Matches Yes – Relatives in Common Yes – Review DNA Match Yes – People who match both or 1 of 2 kits
Relationship Between Shared Matches No No No Yes, under shared match No

Mitochondrial DNA Yes, full sequence, matching, refined haplogroup No High-level haplogroup only, no matching No No, only if tester enters haplogroup manually

*Autoclusters through Genetic Affairs show cluster relationships of matches to the tester and to each other, but not all matches are included, including close matches. While this is a great tool, it’s not relevant for determining close and sibling relationships. See the article, AutoClustering by Genetic Affairs, here.

Additional Resources

Some of you may be wondering how endogamy affects sibling numbers.

Endogamy makes almost everything a little more complex. I wrote about endogamy and various ways to determine if you have an endogamous heritage, here.

Please note that half-siblings with high cM matches also fall into the range of full siblings (1613-3488), with or without endogamy. This may be, but is not always, especially pronounced in endogamous groups.

As another resource, I wrote an earlier article, Full or Half Siblings, here, that includes some different examples.

Strategy

You have a lot of quills in your quiver now, and I wish you the best if you’re trying to unravel a siblingship mystery.

You may not know who your biological family is, or maybe your sibling doesn’t know who their family is, but perhaps your close relatives know who their family is and can help. Remember, the situation that has revealed itself may be a shock to everyone involved.

Above all, be kind and take things slow. If your unexpected sibling match becomes frightened or overwhelmed, they may simply check out and either delete their DNA results altogether or block you. They may have that reaction before you have a chance to do anything.

Because of that possibility, I recommend performing your analysis quickly, along with taking relevant screenshots before reaching out so you will at least have that much information to work with, just in case things go belly up.

When you’re ready to make contact, I suggest beginning by sending a friendly, short, message saying that you’ve noticed that you have a close match (don’t say sibling) and asking what they know about their family genealogy – maybe ask who their grandparents are or if they have family living in the area where you live. I recommend including a little bit of information about yourself, such as where you were born and are from.

I also refrain from using the word adoption (or similar) in the beginning or giving too much detailed information, because it sometimes frightens people, especially if they know or discover that there’s a painful or embarrassing family situation.

And, please, never, ever assume the worst of anyone or their motives. They may be sitting at their keyboard with the same shocked look on their face as you – especially if they have, or had, no idea. They may need space and time to reach a place of acceptance. There’s just nothing more emotionally boat-capsizing in your life than discovering intimate and personal details about your parents, one or both, especially if that discovery is disappointing and image-altering.

Or, conversely, your sibling may have been hoping and waiting just for you!

Take a deep breath and let me know how it goes!

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 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.

 Tool 23andMe Ancestry FamilyTreeDNA MyHeritage GEDMatch
Ethnicity Yes Yes Yes Yes Use the vendors
Ethnicity Painting Yes + segments Yes, limited Yes + segments Yes
Ethnicity Phasing Yes Partial Yes No
DNA Communities No Yes No No
Genetic Groups No No No Yes

Discover Y DNA – public No No Yes No
ROH No No No No Yes

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.

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
Genetic Groups 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

Public Y Tree Yes for locations Yes for locations
Public Mito Tree Yes for locations Yes for locations
Discover Y DNA Yes, for heritage information Yes, for heritage information
Parents Related – ROH Possibly Less useful

In Search of…Vendor Features, Strengths, and Testing Strategies

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

In this article, we are going to discuss your goals and why testing or uploading to multiple vendors is advantageous – even if you could potentially solve the initial mystery at one vendor. Of course, the vendor you test with first might not be the vendor where the mystery will be solved, and data from multiple vendors might just be the combination you need.

Testing Strategy – You Might Get Lucky

I recommended in the first article that you go ahead and test at the different vendors.

Some people asked why, and specifically, why you wouldn’t just test at one vendor with the largest database first, then proceed to the others if you needed to.

That’s a great question, and I want to discuss the pros and cons in this article more specifically.

Clearly, that is one strategy, but the approach you select might differ based on a variety of considerations:

  • You may only be interested in obtaining the name of the person you are seeking – or – you may be interested in finding out as much as possible.
  • You may find that your best match at one company is decidedly unhelpful, and may even block you or your efforts, while someone elsewhere may be exactly the opposite.
  • Solving your mystery may be difficult and painful at one vendor, but the answer may be infinitely easier at a different vendor where the answer may literally be waiting.
  • There may not be enough, or the right information, or matches, at any one vendor, but the puzzle may be solvable by combining information from multiple vendors and tests. Every little bit helps.
  • You may have a sense of urgency, especially if you hope to meet the person and you’re searching for parents, siblings or grandparents who may be aging.
  • You may be cost-sensitive and cannot afford more than one test at a time. Fortunately, our upload strategy helps with that too. Also, watch for vendor sales or bundles.

From the time you order your DNA test, it will be about 6-8 weeks, give or take a week or two in either direction, before you receive results.

When those results arrive, you might get lucky, and the answer you seek is immediately evident with no additional work and just waiting for you at the first testing company.

If that’s the case, you got lucky and hit the jackpot. If you’re searching for both parents, that means you still have one parent to go.

Unidentified grandparents can be a little more difficult, because there are four of them to sort between.

If you discover a sibling or half-sibling, you still need to figure out who your common parent is. Sometimes X, Y, and mitochondrial DNA provides an immediate answer and is invaluable in these situations.

It’s more likely that you’ll find a group of somewhat more distant relatives. You may be able to figure out who your common grandparents or great-grandparents are, but not your parent(s) initially. Often, the closer generation or two is actually the most difficult because you’re dealing with contemporary records which are not publicly available, fewer descendants, and the topic may be very uncomfortable for some people. It’s also complicated because you’re often not dealing with “full” relationships, but “half,” as in half-sibling, half-niece, half-1C, etc.

You may spend a substantial amount of time trying to solve this puzzle at the first vendor before ordering your next test.

That second test will also take about 6-8 weeks, give or take. I recommend that you order the first two autosomal tests, now.

Order Your First Two Autosomal Tests

The two testing companies with the largest autosomal databases for comparison, Ancestry, and 23andMe, DO NOT accept DNA file uploads from other companies, so you’ll need to test with each individually.

Fortunately, you CAN transfer your autosomal DNA tests to both MyHeritage and FamilyTreeDNA, for free.

You will have different matches at each company. Some people will be far more responsive and helpful than others.

I recommend that you go ahead and order both the Ancestry and 23andMe tests initially, then upload the first one that comes back with results to both FamilyTreeDNA and MyHeritage. Complete, step-by-step download/upload instructions can be found here.

You can also upload your DNA file to a fifth company, Living DNA, but they are significantly smaller and heavily focused on England and Great Britain. However, if that’s where you’re searching, this might be where you find important matches.

You can also upload to GEDMatch, a popular third-party database, but since you’re going to be in the databases of the four major testing companies, there is little to be gained at GEDMatch in terms of people who have not tested at one of the major companies. Do NOT upload to GEDMatch INSTEAD of testing or uploading to the four major sites, as GEDMatch only has a small fraction of the testers in each of the vendor databases.

What GEDMatch does offer is a chromosome browser – something that Ancestry does NOT offer, along with other clustering tools which you may find useful. I recommend GEDMatch in addition to the others, if needed or desired.

Ordering Y and Mitochondrial DNA Tests

We reviewed the basics of the different kinds of DNA, here.

Some people have asked why, if autosomal DNA shows relatives on all of your lines, would one would want to order specific tests that focus on just one line?

It just so happens that the two lines that Y and mitochondrial DNA test ARE the two lines you’re seeking – direct maternal – your mother (and her mother), and direct paternal, your father (and his father.)

These two tests are different kinds of DNA tests, testing a different type of DNA, and provide very focused information, and matches, not available from autosomal DNA tests.

For men, Y DNA can reveal your father’s surname, which can be an invaluable clue in narrowing paternal candidates. Knowing that my brother’s Y DNA matched several men with the surname of Priest made me jump for joy when he matched a woman of that same last name at another vendor.

Here’s a quote from one of the members of a Y DNA project where I’m the volunteer administrator:

“Thank you for your help understanding and using all 4 kinds of my DNA results. By piecing the parts together, I identified my father. Specifically, without Y DNA testing, and the Big Y test, I would not have figured out my parental connection, and then that my paternal line had been assigned to the wrong family. STR testing gave me the correct surname, but the Big Y test showed me exactly where I fit, and disproved that other line. I’m now in touch with my father, and we both know who our relatives are – two things that would have never happened otherwise.”

If you fall into the category of, “I want to know everything I can now,” then order both Y and mitochondrial DNA tests initially, along with those two autosomal tests.

You will need to order Y (males only) and mitochondrial DNA tests separately from the autosomal Family Finder test, although you should order on the same account as your Family Finder test at FamilyTreeDNA.

If you take the Family Finder autosomal test at FamilyTreeDNA or upload your autosomal results from another vendor, you can simply select to add the Y and mitochondrial DNA tests to your account, and they will send you a swab kit.

Conversely, you can order either a Y or mitochondrial DNA test, and then add a Family Finder or upload a DNA file if you’ve already taken an autosomal DNA test to that account too. Note – these might not be current prices – check here for sales.

You will want all 3 of your tests on the same account so that you can use the Advanced Matches feature.

Using Advanced Matches, you’ll be able to view people who match you on combinations of multiple kinds of tests.

For example, if you’re a male, you can see if your Y DNA matches also match you on the Family Finder autosomal test, and if so, how closely?

Here’s an example.

In this case, I requested matches to men with 111 markers who also match the tester on the Family Finder test. I discovered both a father and a full sibling, plus a few more distant matches. There were ten total combined matches to work with, but I’ve only shown five for illustration purposes.

This information is worth its weight in gold.

Is the Big Y Test Worth It?

People ask if the Big Y test is really worth the extra money.

The answer is, “it depends.”

If all you’re looking for are matching surnames, then the answer is probably no. A 37 or 111 marker test will probably suffice. Eventually, you’ll probably want to do the Big Y, though.

If you’re looking for exact placement on the tree, with an estimated distance to other men who have taken that test, then the answer is, “absolutely.” I wish the Big Y test had been available back when I was hunting for my brother’s biological family.

The Big Y test provides a VERY specific haplogroup and places you very accurately in your location on the Y DNA tree, along with other men of your line, assuming they have tested. You may find the surname, as well as being placed within a generation or a few of current in that family line.

Additionally, the Discover page provides estimates of how far in the past you share a common ancestor with other people that share the same haplogroup. This can be a HUGE boon to a male trying to figure out his surname line and how closely in time he’s related to his matches.

Big Y NPE Examples

Y DNA SNP mutations tested with the Big Y test accrue a mutation about every generation, or so. Sometimes we see mutations in every generation.

Here’s an example from my Campbell line. Haplogroups are listed in the top three rows.

I created this spreadsheet, but FamilyTreeDNA provides a block tree for Big Y testers. I’ve added the genealogy of the testers, with the various Big Y testers at the bottom and common ancestors above, in bold.

We have two red NPE lines showing. The MacFarlane tester matches M. Campbell VERY closely, and two Clark males match W. Campbell and other Campbells quite closely. We utilized autosomal plus the Y results to determine where the unknown parentage events occurred. Today, if you’re a Clark or MacFarlane male, or a male by any other surname who was fathered by a Y chromosome Campbell male (by any surname), you’ll know exactly where you fit in this group of testers on your direct paternal line.

Y DNA is important because men often match other men with the same surname, which is a HUGE clue, especially in combination with autosomal DNA results. I say “often,” because it’s possible that no one in your line has tested, or that your father’s surname is not his biological surname either.

Y and mitochondrial DNA matches can be HUGELY beneficial pieces of information either by confirming a close autosomal relationship on that line, or eliminating the possibility.

Lineage-Specific Population Information

In addition to matching other people, both Y and mitochondrial DNA tests provide you with lineage-specific population or “ethnicity” information for this specific line which helps you focus your research.

For example, if you view the Y DNA Haplogroup Origins shown for this tester, you’ll discover that these matches are Jewish.

The tester might not be Jewish on any other genealogical line, but they definitely have Jewish ancestry on their Y DNA, paternal, line.

The same holds true for mitochondrial DNA as well. The main difference with mitochondrial DNA is that the surname changes with each generation, haplogroups today (pre-Million Mito) are less specific, and fewer people have been tested.

Y and Mitochondrial DNA Benefits

Knowing your Y and mitochondrial DNA haplogroups not only arm you with information about yourself, they provide you with matching tools and an avenue to include or exclude people as your direct line paternal or maternal ancestors.

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

For example, both Jewish and Native populations are endogamous populations, meaning highly intermarried for many generations into the past.

Knowing that helps you adjust your autosomal relationship analysis.

Why Order Multiple Tests Initially Instead of Waiting?

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

Do you want to wait 6-8 months for all of your results? Can you afford to?

Part of this answer has to do with what, exactly, you’re seeking, and how patient you are.

Only you can answer that question.

A Name or Information?

Are you seeking the name or identity of a person, or are you seeking information about that person?

Most people don’t just want to put a name to the person they are seeking – they want to learn about them and the rest of the family that door opens.

You will have different matches at each company. Even after you identify the person you seek, the people you match may have trees you can view, with family photos and other important information. (Remember, you can’t see living people in trees.) Your matches may have first-person information about your relative and may know them if they are living, or have known them.

Furthermore, you may have the opportunity to meet that person. Time delayed may not be able to be recovered or regained.

One cousin that I assisted discovered that his father had died just six weeks before he broke through that wall and made the connection.

Working with data from all vendors simultaneously will allow you to combine that data and utilize it together. Using your “best” matches at each company, augmented by X, Y, and/or mitochondrial DNA, can make MUCH shorter work of this search.

Your closest autosomal matches are the most important and insightful. In this series, I will be working with the top 15 autosomal results at each vendor, at least initially. This approach provides me with the best chance of meaningful close relationship discoveries.

Data and Vendor Results Integration

Here’s a table of my two closest maternal and paternal matches at the four major vendors. I can assign these to maternal or paternal sides, because I know the identity of my parents, and I know some of these people. If an adoptee was doing this, the top 4 could all be from one parent, which is why we work with the top 15 or so matches.

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

To be clear, I tested my mother’s mitochondrial DNA before she passed away, but because FamilyTreeDNA archives DNA samples for 25 years, as the owner/manager of her DNA kit, I was able to order the Family Finder test after she had passed away. Her tests are invaluable today.

Then, years later, I uploaded her results to MyHeritage.

If I was an adopted child searching for my mother, I would find her results in both databases today. She’ll never be at either 23andMe or Ancestry because she passed away before she could test there and they don’t accept uploads.

Looking at the other vendors, my half-niece at MyHeritage is my paternal half-sibling’s daughter. My half-sibling is deceased, so this is as close as I’ll ever get to matching her.

At 23andMe, the half-great-niece is my half-siblings grandchild.

It’s interesting that I have no matches to descendants of my other half-sibling, who is also deceased. Maybe I should ask if any of his children or grandchildren have tested. Hmmmm…..

You can see that I stand a MUCH BETTER chance of figuring out close relatives using the combined closest matches of all four databases instead of the top matches from just one database. It doesn’t matter if the database is large if the right person or people didn’t test there.

Combine Resources

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

You may also discover that the door slams shut with some people, or they may not respond to your queries, but another match may be unbelievably helpful. Don’t limit your possibilities.

Let’s take a look at the strengths of each vendor.

Vendor Strengths and Things to Know

Every vendor has product strengths and idiosyncracies that the others do not. All vendors provide matches and shared matches. Each vendor provides ethnicity tools which certainly can be useful, but the features differ and will be covered elsewhere.

  • AncestryAncestry has the largest autosomal database and includes ThruLines, but no Y or mitochondrial DNA testing, no clusters, no chromosome browser, no triangulation, and no X chromosome matching or reporting. Ancestry provides genealogical records, advanced tools, and full tree access to your matches’ trees with an Ancestry subscription. Ancestry does not allow downloading your match list or segment match information, but the other vendors do.
  • 23andMe 23andMe has the second largest database. They provide triangulation and genetic trees that include your closest matches. Many people test at 23andMe for health and wellness information, so 23andMe has people in their database who are not specifically interested in genealogy and probably won’t have tested elsewhere, but may be invaluable to your search. 23andMe provides Y and mtDNA high-level haplogroups only, but no matching or other haplogroup information. If you purchase a new test or have a V5 ancestry+health current test, you can expand your matches from a limit of 1500 to about 5000 with an annual membership. For seeking close relatives, you don’t need those features, but you may want them for genealogy. 23andMe is the only vendor that limits their customers’ matches.
  • MyHeritageMyHeritage has the third largest database that includes lots of European testers. MyHeritage provides triangulation, Theories of Family Relativity, and an integrated cluster tool* but does not report X matches and does not offer Y or mitochondrial DNA testing. MyHeritage accepts autosomal DNA file uploads from other testing companies for free and provides access to advanced DNA features for a one-time unlock fee. MyHeritage includes genealogical records and full feature access to advanced DNA tools with a Complete Subscription. (Free 15 days trial subscription, here.)
  • FamilyTreeDNA Family Finder (autosomal)FamilyTreeDNA is the oldest DNA testing company, meaning their database includes people who initially tested 20+ years ago and have since passed away. This, in essence, gets you one generation further back in time, with the possibility of stronger matches. Their Family Matching feature buckets and triangulates your matches, assigning them to your maternal or paternal sides if you link known matches to their proper place in your tree, even if your parents have not tested. FamilyTreeDNA accepts uploads from other testing companies for free and provides advanced DNA features for a one time unlock fee.
  • FamilyTreeDNAFamilyTreeDNA is the only company that offers both Y and mitochondrial DNA testing products that include matching, integration with autosomal test results, and other tools. These two tests are lineage-specific and don’t have to be sorted from your other ancestral lines.

I wrote about using Y DNA results, here.

I wrote about using mitochondrial DNA results, here.

*Third parties such as Genetic Affairs provide clustering tools for both 23andMe and FamilyTreeDNA. Clustering is integrated at MyHeritage. Ancestry does not provide a tool for nor allow third-party clustering. If the answer you seek isn’t immediately evident, Genetic Affairs clustering tools group people together who are related to each other, and you, and create both genetic and genealogical trees based on shared matches. You can read more about their tools, here.

Fish in all the Ponds and Use All the Bait Possible

Here’s the testing and upload strategy I recommend, based on the above discussion and considerations. The bottom line is this – if you want as much information as possible, as quickly as possible, order the four tests in red initially. Then transfer the first autosomal test results you receive to the two companies identified in blue. Optionally, GEDMatch may have tools you want to work with, but they aren’t a testing company.

What When Ancestry 23andMe MyHeritage FamilyTreeDNA
Order autosomal Initially X X    
Order Y 111 or Big-Y DNA test if male Initially       X
Order mitochondrial DNA test Initially if desired       X
Upload free autosomal When Ancestry or 23andMe results are available     X X
Unlock Advanced Tools When you upload     $29 $19
Optional GEDMatch free upload If desired, can subscribe for advanced tools

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

Multiple vendor sites will hopefully provide multiple close matches, which increase your opportunity to discover INFORMATION about your family, not just the identity of the person you seek.

Or maybe you prefer to wait and order these DNA tests serially, waiting until one set of results is back and you’re finished working with them before ordering the next one. If so, that means you’re a MUCH more patient person than me. 😊

Our next article in this series will be about endogamy, how to know if it applies to you, and what that means to your search.

Barbara Sing, Seng or Sang (1645-1686), Childbirth Claimed Her – 52 Ancestors #364

Barbara Sing, Seng or Sang was born in Endersbach, Germany in 1645 to Hans Sing/Sang and Barbara Eckardt.

She was surely baptized in the church there, but records don’t exist from the period of the Thirty Years’ War.

Endersbach is just a mile and a quarter up the road from Beutelsbach.

There seemed to be a lot of interaction and intermarriage occurring between Beutelsbach and Endersbach families.

It’s interesting that while, according to the local heritage book, her father, Hans Sang was born in Endersbach, Barbara was the only one of her siblings born there.

Her mother, Barbara Eckardt was born in Beutelsbach, so clearly, the couple chose to live there after their marriage.

The fact that only one child was born in Endersbach, and that birth was during the 30 Years War makes me wonder if the family had to seek refuge in Endersbach during that timeframe.

The Beutelsbach records resume in 1646. We find Barbara’s younger sibling born in Beutelsbach on March 6, 1648. It’s possible that Barbara had a sibling born between 1645 and 1648 in Endersbach or elsewhere.

During the war, record-keeping either wasn’t possible or didn’t bubble up to the top of the priority list when simple survival was a struggle. The people had been brutalized by marauding armies and soldiers for, literally, 30 years – more than a generation. Farms, villages, and entire cities were burned, and their fields ruined. Food was scarce and no one was ever safe.

We know that Barbara was raised in Beutelsbach from 1648 forward, so from the time she was about three years old.

Martin Goll, historian and Beutelsbach resident tells us that Barbara was the daughter of Hans Sang who was a butcher and quite wealthy, at least comparatively, after the Thirty Years War.

8 Marktplatz

The Hans Sang home and butcher shop was located at 8 Marktplatz in Beutelsbach which still exists today, adjacent the fortified gate of the Beutelsbach church.

The home of Barbara’s beau and future husband, Hans Lenz, the son of another wealthy merchant was only 100 feet or so distant at Stiftstrasse 17..

The church, of course, was both the center of Beutelsbach and the center of the community. Having a shop near the church assured that parishioners would pass by your door several times a week.

Having the shop right next to the steps of the fortified tower entrance to the church assured that no one would forget to purchase meats. Today, someone would be out front giving samples and coupons to hungry parishioners after Sunday services😊.

In this photo of the church and tower, the building connected to the tower on the right, directly in front of the white automobile, is the Sing home, 8 Marktplatz.

We are fortunate to have a drawing of Beutelsbach from 1760.

The round fortified tower is visible to the right of the road, with the first house attached to that tower being the Sang home, pointed out by the yellow arrow. The Lenz home is the red arrow, as best I can tell.

This postcard from 1916 shows the gate, church, and adjacent buildings as well. I wonder if the drawing was from an earlier era.

Literally, everyone going to church passed by the door of the butcher shop.

Most villages only had one person practicing any profession, so Hans Sang was probably the only game in town anyway. I hope he did the actual butchering elsewhere, or at least not during church services.

Perhaps the good smells from the Lenz bakery a few feet away helped to overcome the odors emanating from the butcher’s shop which would have been attached to their home. Yes indeed, much more desirable to be the baker’s child.

Marriage

Barbara Sing married Hans Lenz on February 23, 1669, in Beutelsbach, in the church right next to her home.

Sharon Hockensmith took this photo inside the church when she was visiting. I don’t know how much of the interior was the same in 1669, but we can rest assured that the primary structure didn’t change. The choir loft, organ, and windows are likely original.

We don’t know if the custom of the time was to be married in the church proper, or in the adjacent parsonage. Regardless, Barbara and Hans would have attended this church every Sunday during their marriage, except when war, danger, childbirth, or illness interfered.

They probably saw this exact same scene hundreds of times, only with people dressed in clothing of their period.

Children

Barbara’s parents and in-laws were apparently both wealthy, but money can’t buy everything. In fact, it can’t purchase the things we cherish most in life.

Barbara and Hans had 11 children, beginning with their first child who was born in the late fall of 1669.

  • Anna Katharina Lenz was born on November 19, 1669, and married Simon Dendler, a widower from Schnait, on November 30, 1693, in Beutelsbach. However, Martin found no children in the church records. We don’t know what happened to Anna Katharina. They could have moved away and had children elsewhere.
  • Margaretha Lenz was born on January 24, 1671, and died July 13, 1678, in Beutelsbach, only 7 years old.
  • Barbara Lenz was born on March 10, 1672, and died July 11, 1678, two days before her sister, Margaretha. She was 6 years old.

These two sisters passing away two days apart tell us that either there was a communicable illness being passed around, or there was an outbreak of dysentery or something similar. As the only non-infant girls in the family, they probably slept together.

It may not have been a coincidence that the next year, 1679, saw a massive outbreak of plague. We know that malaria was present in Europe in 1678, having arrived on ships from Africa, but Beutelsbach is not a port city. I can’t help but wonder who else in the family was ill, and how many more Beutelsbach residents died in the summer of 1678.

Barbara, four months pregnant at the time, must have been heartbroken, losing her two little girls just two days apart.

  • Johann Georg Lenz was born on February 21, 1674, and died on April 2, 1758, in Beutelsbach of old age at 84. He married Sibilla Muller on February 2, 1698, also in Beutelsbach. After his parents passed away, he and Sibilla lived in the home place, continuing the vinedresser and vintner profession. Unfortunately, Johann George’s back was injured by falling stones. They had 8 children, 3 or 4 of whom lived to adulthood. Johann George and Sibilla are my ancestors.
  • Daniel Lenz was born November 14, 1675, and died November 7, 1758, seven months after his older brother. He married Anna Katharina Lang in 1702 and they had 8 children, 3 of whom lived to adulthood. Daniel was a vintner as well, but was described as having “stupid eyes” which likely meant he was either partially blind or cross-eyed. He did field work, fell down from an apple tree, and nearly died another time from choking on his own blood. Daniel couldn’t read but was an avid churchgoer and seemed to have a good life in spite of having “stupid eyes.”
  • Elisabetha Lenz was born July 27, 1677, and no death or marriage records are found for her, nor are any children’s baptismal records. She likely died young. I wonder if she died in the same outbreak that took her two sisters in July of 1678.
  • Anna Maria Lenz was born December 19, 1678, and died May 5, 1721, in Beutelsbach from a tumor. I’d love to know what kind of a tumor. She married Hans Jakob Bechtel about 1698. He was a baker, then a judge, and eventually, mayor. They had 12 children, 6 of whom lived to adulthood.
  • Johann Jakob Lenz, a vinedresser and vintner, was born April 19, 1680, and died on May 6, 1744, in Beutelsbach of “high-temperature gastric fever” which was probably dysentery, also known as “bloody flux.” He married Anna Katharina Knodler in 1717 in Grunbach. They had 8 children, of which two lived to adulthood. Two others died as young adults before marrying. Their last child was listed as “simple” at his baptism and likely did not survive.
  • Philip Lenz was born on November 2, 1681, and died September 24, 1737, in Beutelsbach at 56 years of age of melancholy. He was a vintner and married Justina Bohringer in 1716. They had 5 children, of whom 2 lived to adulthood and one died as a young adult of heatstroke.
  • Martin Lenz was born November 11, 1683, and died a few days later on November 27th.
  • Barbara Lenz, the last child, probably named for her mother, was born July 2, 1686. She died 25 days later, on July 27th, 17 days after her mother. Clearly, complications of childbirth took both mother and child.

Of the 41 grandchildren we know were born to Barbara, only 16 or 17 survived to adulthood. That’s a 61% mortality rate, meaning almost two-thirds of the children didn’t live to marriage age.

The Grim Reaper

The Grim Reaper is merciless.

Barbara Sing died on July 10, 1686. We don’t know why, other than it was assuredly something to do with childbirth. It could have been Puerperal Fever, also known as childbed fever, which can lead to blood poisoning. However, her death could also have been a result of a hemorrhage, internal damage, or loss of a large amount of blood.

Given that the child died too, I’d be inclined to think that perhaps childbed fever was the culprit as a result of a long labor. The long labor could have caused the child’s death as well, especially if something went wrong, such as a breach birth.

Regardless, Barbara was gone. She was only 40 or 41 years old, and left several children behind.

  • Katherina was 17
  • Johann George was 12
  • Daniel was 10
  • Elisabetha, if she was living, would have turned 9 on the day her new sister, Barbara, died
  • Anna Maria was 7
  • Johann Jakob was 6
  • Philipp was 4

Barbara had to wonder, as she was desperately ill, who would raise her children?

Who would kiss their boo-boos?

Who would take care of them?

Fix their favorite foods?

Hold and comfort them?

Who would love them the way she loved them?

Would they remember her?

What about her newborn baby? Would she survive? How, without her mother’s milk?

And what was her husband, Hans, to do?

How could he possibly tend the vineyards, press the grapes, produce wine and maintain his business selling wines while looking after 7 or 8 children?

He couldn’t exactly take all the children to the fields with him, especially not a baby.

Those questions cross the mind of every mother from time to time. However, in Barbara’s case, this was very real and pressing – not an abstract thought.

Unfortunately, the Grim Reaper visited all too often in the days before antibiotics and modern medicine.

The good news, or bad news, or both, was that there were others in the same situation. Joining forces made sense.

A Step-Mother for Barbara’s Children

Barbara didn’t exactly get to select her successor – the woman who would raise her children after she could no longer do so.

Hans waited a respectable amount of time before remarrying, 12 months to be exact. The banns had to be posted for 3 weeks, and the minister would have posted and read the marriage banns on the first Sunday following the 1-year anniversary of Barbara’s death, inviting anyone who had any knowledge of why the couple shouldn’t marry to come forth.

On August 2, 1687, Hans married Barbara Roller(in) who was the widow of Sebastian Heubach from Endersbach. Barbara was born in 1748, so she would have been 39 years old when she married Hans. However, we find no children born to them, nor do I find any record of children born from her first marriage either, which occurred in 1672.

If Barbara already had children, she and Hans joined their families when they wed. If not, then perhaps Barbara welcomed the opportunity to become a mother and love the first Barbara Lenz’s children.

Step-parents are the parents who choose us.

Mitochondrial DNA Candidates

Mitochondrial DNA is a special type of DNA passed from mothers to their children, but only passed on by daughters. It’s never admixed with the DNA of the father, so it is passed on essentially unchanged, except for an occasional small mutation, for thousands of years. Those small mutations are what make this DNA both genealogically useful and provide a key to the past.

By looking at Barbara’s mitochondrial DNA, we can tell where her ancestors came from by evaluating information provided by the trail of tiny mutations.

Only one of Barbara’s daughters, Anna Maria who married Hans Jakob Bechtel (Bechthold,) is known to have lived to have children. Although, if two other daughters lived, it’s possible that either Anna Katharina (born 1669) or Elisabetha (born 1677) married and had children elsewhere.

Anna Maria Lenz Bechtel had two daughters who lived to adulthood, but only one married.

  • Anna Maria Bechtel was born in 1715 and married Jakob Siebold/Seybold of Grunbach. Their children were all born in Remshalden.
    • Anna Maria Seybold was born  in 1737 and married Johann Jacob Lenz in 1761, children unknown
    • Regina Dorothea Seybold was born in 1741, married Johann Wolfgang Bassler in 1765, and had one known daughter.
      • Johanna Bassler was born in 1785, married Johannes Wacker in 1814, and had three daughters, Johanna Elisabetha (1818), Dorothea Catharina (1822), and Carolina Friederica (1825.)
    • Anna Catharina Seybold born in 1751 married Johann Leonhard Wacker in 1813 in Remshalden. No known daughters.
    • Elisabeth Seybold born in 1752 married Johann Michael Weyhmuller in 1780 in Remshalden and had three daughters who lived to adulthood, married, and had daughters.
      • Anna Maria Weyhmuller born 1785, married Eberhard Sigmund Escher from Esslingen in 1807, but children are unknown.
      • Regina Dorothea Weyhmueller born 1787 and married Salomo Dautel in 1814 in Remshaulden. They immigrated to America in 1817, location and children unknown.
      • Elisabetha Weyhmueller born in 1792 and had daughter Jakobine Hottmann in 1819 with Daniel Hottmann. She then married Wilhelm Friedrich Espenlaub and had Josephina Friederika Espenlaub in 1830. Children unknown.

For anyone who descends from Barbara Sing through all females to the current generation, which can be male, I have a DNA testing scholarship for you.

Please reach out! Let’s see what we can discover about Barbara together!

Just Released – Mitochondrial Haplogroup L7 Video!

I’m still VERY excited about the haplogroup L7 discovery. Mitochondrial Eve’s new 100,000-year-old great-granddaughter. So is the rest of the Million Mito Team

We’ve created a short video explaining just why this is so cool.

Paul, Dr. Maier, the Population Geneticist on our Million Mito team did a great job as producer. He’s certainly multi-talented! Thanks Paul.

Please understand that this is “just us,” no professional production, editors or anything like that. You’re seeing the real deal here. This video is something we wanted to do for all of you. We’re excited to tell this amazing story – one that we’ve explained in terms that everyone can understand and enjoy. We want you to love mitochondrial DNA as much as we do.

Please share this video far and wide with your family and friends. Remind them that everyone inherits their mother’s (and only their mother’s) mitochondrial DNA. They can make cool discoveries too.

But wait, there’s more!

Dr. Miguel Vilar’s Article

FamilyTreeDNA just published a guest blog article titled A 100,000Year-Old Human Lineage Rediscovered, written by genetic anthropologist Dr. Miguel Villar.

You’ll recognize Miguel as one of the four Million Mito team members in the video, but you may also remember him as the Senior Program Officer for the National Geographic Society and the Lead Scientist for the Genographic Project.

I think you’ll agree, he’s a great writer too!

What’s Your Story?

Not only is mitochondrial DNA (mtDNA) useful genealogically, it’s the story of all womankind. You don’t have to be a genealogist to appreciate and enjoy your mtDNA journey.

Mitochondrial DNA tells a story about each of us that we would never know otherwise.

The best part is that every single person can test their own mitochondrial DNA to learn more about their family story – and very specifically about their mother’s direct line ancestry that may be eclipsed or overshadowed in autosomal DNA by more recent admixture.

Where does your mitochondrial DNA lead?

What Else Can You Do?

You, your mother, and your maternal siblings all share the same mitochondrial DNA, passed to you by your mother. But what about your father? He inherited HIS mother’s mitochondrial DNA, but you didn’t.

You can discover your paternal grandmother’s mtDNA story by testing your father’s mtDNA, or his maternal line siblings if he’s not available for testing.

Your paternal grandmother’s story is your family story too!

Let me know if you like the video and if it makes mtDNA easier to understand and explain to your relatives. I hope this discovery and video help sew the seeds of curiosity.

Mitochondrial Eve Gets a Great-Granddaughter: African Mitochondrial Haplogroup L7 Discovered

Such wonderful news today!

We have a birth announcement, of sorts, detailed in our new paper released just today,  “African mitochondrial haplogroup L7: a 100,000-year-old maternal human lineage discovered through reassessment and new sequencing.”

Woohoo, Mitochondrial Eve has a new great-granddaughter!

Back in 2018, Goran Runfeldt and Bennett Greenspan at FamilyTreeDNA noticed something unusual about a few mitochondrial DNA sequences, but there weren’t enough sequences to be able to draw any conclusions. As time went on, more sequences became available, both in the FamilyTreeDNA database and in the academic community, including an ancient sequence.

This group of sequences did not fit cleanly into the phylogenetic tree as structured and seemed to cluster together, but more research and analysis were needed.

Were these unique sequences a separate branch? One branch or several? What would creating that branch do to the rest of the tree?

Given that Phylotree, last updated in 2016, did not contain an applicable branch, what were we to do with these puzzle pieces that really didn’t fit?

These discussions, and others similar, led to the decision to launch the Million Mito Project to update the mitochondrial phylogenetic tree which is now 6 years old and seriously out-of-date. For the record, phylogenetics on this scale is EXTREMELY challenging, which is probably why Phylotree hasn’t been updated, but that’s a topic for another article, another day. Today is the day to celebrate haplogroup L7.

Haplogroup L7

The Million Mito team knew there were lots of candidate haplogroups waiting to be formed near the ends of the branches of the phylotree, but what we didn’t expect was a new haplogroup near the root of the tree.

Put another way, in terms that genealogists are used to, the new branch is Eve’s great-granddaughter.

Haplogroup L now has 8 branches, instead of 7, beginning with L0. We named this new branch haplogroup L7 in order not to disrupt the naming patterns in the existing tree.

Let’s take a look.

I used the phylogenetic tree from our paper and added Eve.

Just to be clear, we aren’t talking literal daughters and granddaughters. These are phylogenetic daughters which represent many generations between each (known) branch. Of course, we can only measure the branches that survived and are tested today or are found in ancient DNA.

The only way we have of discovering and deciphering Eve and her “tree” of descendants is identifying mutations that occurred, providing breadcrumbs back in time that allow us to reconstruct Eve’s mitochondrial DNA sequence.

Those mutations are then carried forever in daughter branches (barring a back-mutation). This means that, yes, you and I have all of those mutations today – in addition to several more that define our individual branches.

You can see that Eve has two daughter branches. One branch, at left, is L0.

Eve’s daughter to the right, which I’ve labeled, is the path to the new L7 branch.

Before this new branch was identified, haplogroup L5 existed. Now, Eve has a new great-granddaughter branch L5’7 that then splits into two branches; L5 and L7.

L5 is the existing branch, but L7 is the new branch that includes a few sequences formerly misattributed to L5.

Even more exciting, the newly discovered haplogroup L7 has sub-branches too, including L7a, L7a1, L7b1 and L7b2.

In fact, haplogroup L7 has a total of 13 sublineages.

How Cool is This?!!

Haplogroup L7 is 100,000 years old. This is the oldest lineage since haplogroup L5 was discovered 20 years ago. To put this in perspective, that’s about the same time the first full sequence mitochondrial DNA test was offered to genealogists.

It took 20 years for enough people to test, and two eagle-eyed scientists to notice something unusual.

Hundreds of thousands of people have had their mitochondrial DNA tested, and so far, only 19 people are assigned to haplogroup L7 or a subgroup.

One of those people, shown as L7a* on the tree above, is 80,000 years removed from their closest relative. Yes, their DNA is hens-teeth rare. No, they don’t have any matches at FamilyTreeDNA, just in case you were wondering😊

However, in time, as more people test, they may well have matches. This is exactly why I encourage everyone to take a mitochondrial DNA test. If someone is discouraged from testing, you never know who they might have matched – or how rare their DNA may be. If they don’t test, that opportunity is lost forever – to them, to other people waiting for a match, and to science.

Are there other people out there with this haplogroup, in either Africa or the diaspora? Let’s hope so!

With so few L7 people existing today, it looks like this lineage might have been on the verge of extinction at some point, but somehow survived and is now found in a few places around the world.

Ancient DNA

One 16,000-year-old ancient DNA sample from Malawi has been reclassified from L5 to L7.

This figure from the paper shows the distribution of haplogroup L within Africa, and the figure below shows the Haplogroup L7 range within Africa, with Tanzania having the highest frequency. Malawi abuts Tanzania on the Southwest corner.

Where in the World?

Checking on the public tree at FamilyTreeDNA, you can see the new L5’7 branch with L7 and sub-haplogroups beneath.

We find L7 haplogroups in present-day testers from:

  • South Africa
  • Kenya
  • Ethiopia
  • Sudan
  • United Arab Emirates
  • Yemen
  • Tanzania

It’s also found in people who live in two European countries now, but with their roots reaching back into Africa. Surprisingly, no known African-Americans have yet tested with this haplogroup. I suspect finding the haplogroup in the Americas is just a matter of time, and testing.

The FamilyTreeDNA customers who are lucky enough to be in haplogroup L7 have had their haplogroup badges updated.

If you are haplogroup L at FamilyTreeDNA, check and see if you have a new badge.

Credit Where Credit is Due

I want to give a big shout-out to my colleagues and co-authors. Dr. Paul Maier (lead author,) Dr. Miguel Vilar and Goran Runfeldt.

I can’t even begin to express the amount of heavy lifting these fine scientists did on the long journey from initial discovery to publication. This includes months of analysis, writing the paper, creating the graphics, and recording a video which will be available soon.

I’m especially grateful to people like you who test their DNA, and academic researchers who continue to sequence mitochondrial DNA in both contemporary and ancient samples. Without testers, there would be no scientific discoveries, nor genealogy matching. If you haven’t yet tested, you can order (or upgrade) a mitochondrial DNA test here.

I also want to thank both Bennett Greenspan, Founder, and President, Emeritus of FamilyTreeDNA who initially greenlit the Million Mito Project in early 2020, and Dr. Lior Rauschberger, CEO who continues to support this research.

FamilyTreeDNA paid the open access fees so the paper is free for everyone, here, and not behind a paywall. If you’re downloading the pdf, be sure to download the supplements too. Lots of graphics and images that enhance the article greatly.

Congratulations to Mitochondrial Eve for this new branch in her family tree. Of course, her family tree is your family and mine – the family of man and womankind!

Legacy Family Tree Webinar’s Top 10

I received an email from Geoff Rasmussen with Legacy Family Tree Webinars announcing that my webinar, Wringing Every Drop out of Mitochondrial DNA ranked number 5 in the top 10 webinars for May.

Truthfully, I was pleasantly surprised because mitochondrial DNA has often been the “neglected” DNA that we all carry. Hopefully, that “neglected” status will change and more people will test now that they understand how beneficial this tool can be, which means additional and more meaningful matches for all of us.

More than 2,200 people have viewed this webinar so far and received the extensive companion syllabus.

You can watch too by joining Legacy Family Tree Webinars, here, which gives you access to all 1787 webinars, and counting. New webinars are literally added daily, and you can register to watch live webinars along with recently recorded webinars for free for the first 7 days. Take a look.

If you haven’t yet tested your mitochondrial DNA, please do by clicking here.

By taking a mitochondrial DNA test at FamilyTreeDNA, you’ll also become a part of the exciting Million Mito Project which is literally rewriting the history of womankind.

 E-book Release and Lovely Book Review

I received a note from my publisher, Genealogical.com, who is also on Family Tree Magazine’s “Best Of” list again this year, telling me that my book, DNA for Native American Genealogy has been released as an e-book AND has received a major book review by Dr. Margaret McMahon. I think this should count as two really good things, not just one.

I wrote about the contents of my book, here, but Dr. Mac, as she is known, summed things up succinctly in her statement, “This book picks up where the theories end and your work begins.”

That was my goal, to educate my readers, explain the various tests and results, and provide a research roadmap. Do you have a family story of a Native American ancestor? Are you looking for answers?

Dr. Mac’s book review corresponds well with the recent release of the book in e-book (e-Pub) format. Here’s how to order:

Thank You, Thank You

Once again, thank you for your continuing support. I’ll have more interesting news soon!

Sarah Rash’s and Perhaps Mary Warren’s Mitochondrial DNA – 52 Ancestors #359

Using the FamilySearch “Relatives at RootsTech” app that was available in the month or so surrounding RootsTech (but not now), I connected with a cousin who is a direct matrilineal descendant of Sarah Rash, our common ancestor.

My cousin, who descends through Sarah’s daughter Rhoda Shepherd, very kindly agreed to take a full sequence mitochondrial DNA test so we now have information about Sarah Rash’s matrilineal origins.

I wrote about Sarah Rash and what we know of her life in Sarah Rash (1748-1829), Church Founder and Grandmother of Nearly 100.

Mitochondrial DNA Inheritance

Women contribute their mitochondrial DNA to all of their children, but only females pass it on. Therefore, mitochondrial DNA is never divided, watered down or mixed with the DNA of the father. Mitochondrial DNA provides an invaluable periscope view directly back in time for our matrilineal ancestors – our direct mother’s, mother’s, mother’s line on up our tree.

Sarah Rash was born to Joseph Rash and wife, Mary, purportedly Mary Warren.  Sarah’s mitochondrial DNA also belongs to her mother Mary. That would be Mary Warren if indeed Mary Warren is Sarah’s mother. Mary Warren’s parents are unknown. However, there is a Warren family in Spotsylvania County, VA, where the Rash family lived in that timeframe.

Goals

My goals for seeking a mitochondrial DNA test for Sarah Rash’s descendant are:

  • To confirm Sarah’s genealogical accuracy by matching another descendant, preferably through another daughter or sister of Sarah.
  • To learn what we can from Sarah’s haplogroup. You don’t know what you don’t know.
  • To gather evidence to confirm or perhaps disprove that Sarah’s mother is Mary Warren.
  • To potentially extend Sarah’s line backward in time.

The Process

Several people have asked me to step through the analysis process that I use for mitochondrial DNA results, so let’s do that.

What can we tell about Sarah’s ancestors through her mitochondrial DNA?.

Sarah’s Matrilineal Line is Not Native

Sometimes when the mother of an early pioneer settler can’t be identified, the “go-to” assumption is that she might be Native American.

Sarah’s haplogroup is U5a2a1d which is definitely NOT Native.

We can dispel this thought permanently.

Since Sarah’s matrilineal ancestors aren’t Native, where are they from?

Where Are Sarah’s Ancestors From?

Using the public mitochondrial tree, here, we see the following countries displayed for haplogroup U5a2a1d.

Sarah’s haplogroup is found most often in the US, which means brick-walled here, followed by England, Ireland, and less-frequent other locations. Note that two people claim Native, the feather, but that can mean either they are mistaken, or they have entered information for their mother’s “side” of the family or their literal “oldest ancestor,” not their specific matrilineal line.

Regardless, haplogroup U is unquestionably not Native.

Matches Map

Sometimes the matches map, which shows the geographic locations of your matches’ most distant matrilineal linear ancestor is very informative, but not so in this case.

Of 74 full sequence matches, only 4, plus the tester whose pin is white, have entered the locations of their matrilineal ancestors.

One of these contains a male name, so we know that’s incorrect.

This is really sad – a wasted opportunity. Imagine how useful this could be with 74 pins instead of 4, and one of those being recorded incorrectly.

Mutations

The mutations tab shows you the mutations you have that are either extra or missing from your haplogroup assignment. This means that these may be combined in the next version of the haplotree to form a new haplogroup.

My cousin has 5 extra mutations, but at least three of those are in unstable areas that I’m sure will not be utilized as haplogroup-forming. The other two mutations are insertions at one single location and I doubt those will be used either.

I wrote about haplogroup formation in the article, Mitochondrial DNA: Part 3 – Haplogroups Unraveled, including a list of unstable and common mutations. Suffice it to say that very common locations like 16519 and 315 insertions aren’t useful to form haplogroups. Some very common mutations, such as insertions at locations 309 and 315 and deletions at 522 and 523 aren’t even counted in matching/differences.

What these unstable mutations actually tell me, relative to Sarah Rash’s DNA is that I need to pay attention to the GD1 (genetic distance of 1) matches, meaning people who have only one mutation difference from my cousin. Given that my cousin’s extra mutations, differences from her defined haplogroup, are in unstable regions, close matches such as GD1 or even GD2 could be quite relevant. It all depends on the difference.

Of course, we can’t see the mutations of the people my cousin matches, so those with a GD1 or GD2 may have mutations on a stable marker that my cousin doesn’t have.

Matches

My cousin has a total of 74 full sequence matches, of which 31 are exact matches, 18 have trees and 12 have listed an earliest known ancestor (EKA). If you haven’t done so, here’s how to enter your EKA.

Of course, the EKA of my cousin’s matches may or may not agree with the earliest matrilineal person in their tree. And the tree may or may not have more than one or two people. Regardless, every hint is worth follow-up.

Think of these as diamonds in the rough.

Trees

I viewed the trees of each of the matches that have uploaded trees. I also made a list of the earliest known ancestors for matches that didn’t have trees so I could be cognizant of watching for those names.

Many trees only had a few generations, but I used Ancestry, FamilySearch, MyHeritage, and WikiTree to see if I could reasonably complete the tree back a little further. Of these, I particularly like WikiTree because I think it tends to be more accurate AND it allows for people to enter that they carry the mitochondrial DNA of specific ancestors. As it turns out, no one has done that for Sarah Rash, or her purported mother, Mary Warren, but if they had, it would provide a confirmation opportunity.

I did find something quite interesting.

Who is Jane Davis?

The EKA of Elizabeth, one of my cousin’s matches, is Jane Davis who was born in 1690.

Unfortunately, Elizabeth did not upload a GEDCOM file or create a tree, so I turned to other trees elsewhere to see what I could unearth about Jane Davis.

I need to state emphatically that what I’m about to tell you needs to be taken with the entire salt lick, not just a grain.

Remember, we’re looking for hints and evidence here, not foregone conclusions – although admittedly, those would be nice.

According to (cringe) some trees, Jane Davis was the wife of one William Warren who was born 1678 in Surry County, VA and died on September 29, 1764 in Edgecombe County, NC. I have not confirmed any of this. Gathering evidence is the first step in the process.

IF this is accurate, William Warren and Jane Davis may be the parents of Mary Warren, the purported mother of Sarah Rash.

Notice all of those weasel words – if, may, purported. That’s where we have to start. In weaselworld.

Obviously, this needs a LOT of traditional genealogy work, but here’s the great news…I now have something to work with and someone else, Elizabeth, who appears one way or another to be descended from this line.

The Good News

Whether or not Jane Davis is accurate or not, I’d wager that we are looking at the same line because Elizabeth matches my cousin’s mitochondrial DNA. I need to email Elizabeth to see if she descends through Sarah Rash. If so, that’s confirmation of this line.

If not, and she descends through a daughter of someone else in this same line, like one of Mary Warren’s sisters, that’s evidence and a HUGE HINT that I can use to confirm Mary Warren as the mother of Sarah Rash. Confirming her mother would also confirm that Mary’s father is William Warren – so would provide evidence for both of Sarah’s parents.

Additional Tools – Advanced Matches

Next, I used Advanced Matches to query for anyone who matches at both the full sequence level and in Family Finder. There were no matches, which doesn’t surprise me since it’s quite a way back in time.

Notice that the link to upload a family tree is in this section, along with the public haplotree I used earlier.

Family Finder

Checking my cousin’s Family Finder matches and searching for surnames, I immediately checked for myself and my known cousins from that line. No cigar, but our common ancestor is many generations in the past.

Checking the Rash surname for my cousin shows a match to someone who descends from Joseph Rash’s brother, William Rash whose children also migrated to Claiborne County, TN along with Sarah Rash’s daughter, Elizabeth Shepherd who married William McNiel.

My cousin has numerous autosomal matches to the McNiel line as well. The Vannoy, McNiel, Shepherd, and Rash lines were all found in Wilkes County, NC together before migrating to Claiborne and Hancock Counties in Tennessee. Before Wilkes County, the Rash, Warren, and McNiel families were in Spotsylvania and nearby counties in Virginia.

Goal Fulfillment

How did we do fulfilling our original goals?

Goal Comment
To confirm Sarah’s genealogical accuracy by matching another descendant. Perhaps – We have that lead to follow up on with Elizabeth and her EKA of Jane Davis. We also have several relevant autosomal matches.
To learn what we can learn from her haplogroup. Yes – Not Native and probably from England or Ireland. That is useful and makes sense.
To confirm her mother as Mary Warren. We now have hints and tools. We need to hear what Elizabeth has to say. I may be able to extract more information by viewing trees individually with people my cousin matches on Family Finder.
To potentially extend Sarah’s line backward in time. We now have a great hint and information to work with, both mitochondrial and autosomal. Jane Davis may be the wife of William Warren, which might well confirm Mary Warren as the daughter of William Warren. It’s too soon to tell but my fingers are crossed for a descendant of Jane Davis from a different daughter through all females.

Sometimes answers come in a gulley-washer, and other times, we have to dig and sift over time for the gems. Let’s create a plan.

What’s Next?

There’s a lot we can do, but maybe one of the best places to start would be to attempt to assemble information about the Warren families of Spotsylvania County, VA. This Thomas Warren might be a good place to begin or maybe work my way up from Mary Warren, here.

I need to focus on both traditional genealogy and genetic autosomal matches at all of the vendors. My cousin’s DNA is only at FamilyTreeDNA, but my results and those of several other cousins are found at several vendors.

I can use Genetic Affairs’ tools to see if I cluster with other people descended from the Warren family. My cousin can set up an account and do the same thing if she wishes. AutoTree and AutoKinship may help with that.

Using traditional genealogy, if I can identify other sisters of Mary Warren (daughters of Jane Davis,) I can ask people descended from them through all females to take a mitochondrial DNA test. If they match my cousin, that’s an exceptionally compelling piece of evidence.

Of course, I can do more work on the mitochondrial DNA matches we already have by emailing and asking for genealogy information. The piece of evidence we need might be right under our noses.

The Warren Family

If you descend from a Warren family in the Spotsylvania County area in the 1600s through 1700s, would you please check your matches to see if you have me, Vannoy, McNiel, McNeil, Rash or Shepherd matches? I’d love to narrow this down.

If you descend through all females from William Warren or another Warren family who would have been having children in the Spotsylvania County from about 1710 to maybe 1740, would you please reach out to me? If we can pinpoint a likely family for Mary Warren who was reportedly born in 1726, I’d love to do a confirming mitochondrial DNA test.

Dorcas Johnson’s Mitochondrial DNA Secret Revealed – 52 Ancestors #357

Dorcas (also spelled Darcus) Johnson was born about 1750 and died about 1835. We know she died in Claiborne County, Tennessee, but the location of her birth has always been assumed to be Virginia.

You know there’s already trouble brewing when you read that assume word, right?

Dorcas, in the early genealogies, was reported to be the daughter of Peter Johnson and Mary Polly Philips, but always a skeptic, I had my doubts. I’m working through the various options to prove or disprove that connection. I wrote about my initial findings, here.

What we do know, positively, about Dorcas is that she married Jacob Dobkins in Dunmore County, Virginia, in 1775. There’s no date listed, but it is shown between the September and October marriages.

Dunmore County was renamed as Shenandoah a few years later, so all of the early Dunmore County records aren’t “missing,” they are Shenandoah County records.

Dorcas and Jacob migrated to eastern Tennesee, probably before Tennessee was even a state n the 1790s, settling in Jefferson County on the White Horn Branch of Bent Creek, Near Bull’s Gap. By 1800, they had moved once again to the fledgling Claiborne County when it was first formed. Dorcas Johnson and Jacob Dobkins spent the rest of their lives in Claiborne County, Tennessee.

The Johnson Books

Peter Johnson’s descendants wrote several early books in the 1900s about that family, specifically focused on the child they descended from. More recently, Eric E. Johnson wrote a book where he distilled the earlier books and added a great deal of original research compiled over decades. Eric has very graciously shared and I am ever so grateful for his generosity.

Dorcas’s Siblings

Not all early books report the same children for Peter Johnson and Mary Polly Philips, so I’ve prepared a composite list of children, as follows:

  • Richard (Derrick, Derrie) Johnson (1746-1818) married Dorcas Dungan in Pennsylvania and later, Elizabeth Nash in Westmoreland County, PA. Richard was born in Cumberland County, PA and died in Jefferson County, Ohio.
  • Dorcas Johnson (c1748/1750 – c1831/1835) married Jacob Dobkins in 1775 in Dunmore/Shenandoah County. Dorcas is reported in one of the early Johnson books and was reported to have married Reuben Dobkins. She married Reuben’s brother, Jacob. Jacob’s other brother, Evan Dobkins, married one Margaret Johnson, earlier in 1775 in the same location where Dorcas married. However, Margaret Johnson is not listed in any of the Johnson books.
  • James Johnson (1752-1826), was born in Pennsylvania and died in Lawrence County, Illinois after having lived in Indiana for some time. He married Elizabeth Lindsay in 1783.
  • Solomon Johnson (1765-1843), apparently the youngest child was born near Greencastle, Cumberland (now Franklin) County, Pennsylvania and died in Forward Township, Allegheny County, PA. He inherited his father’s land and married the neighbor, Frances (Fanny) Warne in 1790. It was Solomon’s Bible records that provided Peter Johnson’s wife’s name as Mary Philips. It’s worth noting that Solomon named a daughter, Dorcas, and the Dorcas Johnson who married Jacob Dobkins named a son Solomon.

Two other sources report Peter’s wife’s first name as Polly which is a well-known nickname for Mary. The only source for Mary Polly Phillips’ surname is the Solomon Johnson Bible.

Four additional daughters are reported with much less specific information available.

  • Mary Johnson – Nothing known.
  • Polly Johnson – Nothing known, although it has been speculated that Mary and Polly were one person, and possibly Richard’s only child by his first wife that Peter Johnson and Mary/Polly Philips took to raise when Richard’s wife died. If this is the case, then Mary would have been born about 1768 and can therefore NOT be the Margaret Johnson who married Evan Dobkins in 1775.
  • Rebecca Johnson, possibly born about 1762. One book states that Rebecca married John Stephens or Stevens and moved to Monongahela County, West Virginia but nothing more is known. This same source states that Stephens served with Richard Johnson in the Revolutionary War, although that could be militia duty. This line needs to be fleshed out and could prove critical. What happened to Rebecca Johnson?
  • Rachel Johnson is reported to have married a John Dobkins and possibly moved to Knox County, Indiana, but nothing more is known. Jacob Dobkins’ brother, John Dobkins married Elizabeth Holman. It’s possible that there’s an unknown brother, or Rachel is the Johnson daughter who married Reuben Dobkins. Dorcas was reported to have married Reuben, but she married Jacob.

In the various Johnson books, two Johnson daughters are reported to have married Dobkins men, and indeed, that’s exactly what happened, but the first names don’t match exactly

If indeed Dorcas Johnson is the full sibling of Mary, Polly, Rebecca or Rachel Johnson, they would carry the same mitochondrial DNA passed to them from their mother – which they in turn would have passed on.

This means that if we can locate someone descended from those daughters through all females to the current generation (which can be male), their mitochondrial DNA should match at the full sequence level.

In summary, we know very little about Mary Polly Philips herself. We don’t know who her parents were, nor if she had siblings. We also don’t really know how many children, specifically daughters, she had.

Where Did Mary Polly Philips Come From?

One of the books reports that Mary Polly Philip’s son, Richard, born in 1746, also known as Derrie, was born in Amsterdam. We know this cannot be true because Peter Johnson and Mary Polly Phillips were already living in Antrim Township of Cumberland County, Pennsylvania by 1742 when he obtained a land grant.

However, since Derrie is a Dutch nickname for Richard, the story that Dorcas was Dutch, or spoke Dutch, may have originated from this nickname. This does beg the question of how Richard obtained that nickname.

The Pennsylvania Dutch settled heavily in Cumberland County where the couple is first found, so it’s possible that Mary Polly may have spoken German. Regardless, one of the family histories states that she didn’t speak English when she married Peter Johnson which raises the question of how they communicated.

Of course, this is confounding given that many early genealogies suggest or state that they were either Scottish, Scots-Irish or Welsh. One history suggests that Peter settled at Wilmington, Delaware, then lived at Head of Elk, Maryland which are both Swedish settlements.

Peter Johnson was supposed to have a brother James and they were both supposed to be from Scotland, with noble peerage, nonetheless.

And another report had Peter sailing from Amsterdam where he had been born.

Clearly these can’t all be true.

Bottom line is this – we don’t know anything about where either Peter or his wife’s families originated. The first actual data we have is Peter’s 1742 land grant in Cumberland County, PA, an area settled by both the Germans and Scots-Irish.

We have a real mystery on our hands.

Not to mention that we still don’t know positively that the Dorcas reported in Peter Johnson’s line who married a Reuben Dobkins is the same person as “my” Dorcas who married Jacob Dobkins. However, given the autosomal matches, I’m quite comfortable at this point, between both documentary and genetic evidence, in confidently adding Peter Johnson and Mary Polly Philips as Dorcas Johnson Dobkins’ parents.

Well, that is, unless someone or something proves me wrong.

One thing is abundantly clear, if Dorcas isn’t their daughter, she’s related to them in some fashion because many of Peter Johnson’s descendants and Dorcas Johnson Dobkins’ descendants match and triangulate when comparing autosomal DNA.

Mitochondrial DNA

Dorcas Johnson inherited her mitochondrial DNA from her mother, whoever that was, who inherited it from her mother, on up the line.

Mitochondrial DNA is never mixed with the DNA of the father, so it’s never divided or diluted. In other words, except for an occasional mutation, it’s passed intact from mothers to all of their children. However, only females pass it on.

In the current generation, males can take a mitochondrial DNA test so long as they descend through all females from the ancestor whose mitochondrial DNA is being sought. In other words, their mother’s mother’s mother’s line on up the tree through all mothers.

I’ve been fortunate enough to find two direct descendants of Dorcas Johnson Dobkins through all female lines (different daughters) who were kind enough to take a mitochondrial DNA test.

Not only did they match each other, they also matched other people at the full sequence level.

What did we discover?

Haplogroup

Dorcas’s descendants were determined to be haplogroup H2a1, a European haplogroup found dispersed widely across Europe.

This can put to rest any speculation about Native American heritage which often arises when a woman’s parents are unknown.

What Information Can Be Gleaned from the Haplogroup Alone?

Using the public mitochondrial DNA tree, we can see that H2a1 is found in 57 countries as identified by testers’ earliest known ancestor (EKA) entries.

This is one reason why it’s important to enter earliest ancestor information (under the gear when you mouse over your name in the upper right-hand corner, under Genealogy in Account Settings.)

But that’s not the only reason to enter as much information as possible. Everyone helps everyone else in genetic genealogy by providing complete information, or as complete as possible.

Matches

Dorcas’s descendants who took the mitochondrial DNA test have a total of 299 HVR1, HVR2 and Coding Region matches. Today, testers can only order the mtFull product which tests the entire 16,569 locations of the mitochondria. Years back, people could order a partial test that only tested part of the mitochondria, called the HVR1 (HVR=Hypervariable Region) or the combined HVR1 & HVR2 regions.

You can select to view matches at the full sequence level, or people you match at the HVR1 or HVR2 level which will include people who did not take the higher mtFull test.

While some people are inclined to ignore their HVR1 and HVR2 results, I don’t because I’m always on the hunt for someone with a common ancestor or other useful information who did NOT test at the full sequence level.

You just never know where you’re going to find that critical match so don’t neglect any potential place to find leads.

To begin, I’m focusing on the full sequence matches that have a genetic distance of 0. GD0 simply means those testers match exactly with no mutations difference.

My cousin has 9 exact matches.

Matilda Holt is Dorcas’s granddaughter.

I viewed the trees for the closest matches and added some additional info.

I viewed the trees, worked several back in time, and found a few other testers who also descend from Dorcas.

One match remains a tantalizing mystery.

Bobby’s line hits a dead-end in Claiborne County, Tennessee, but I cannot connect the dots in Dorcas’s line.

Evan Dobkins, Jacob’s brother who married Margaret Johnson lived in Washington County, VA until the 1790s, but reportedly died in Claiborne County about 1835. Bobby’s EKA could be a grandchild of Dorcas that is previously unknown. She could also be the granddaughter of Margaret Johnson who married Evan Dobkins. I traced his line back to a woman born in 1824 and noted as Catherine Brooks in her marriage to Thomas Brooks in 1847. The Brooks family were close neighbors and did intermarry with the Dobkins family.

I emailed my cousin’s other matches; Karen, Catherine, Leotta, and Betty, and heard back from only one with no information.

With no earliest known ancestor, no tree, and no reply, I’m stuck on these matches, at least for now.

Let’s take a look at the GD1 matches, meaning those with one mutation difference and see what we can find there.

GD1 Matches

My cousin has 36 GD1 matches, meaning one mutation difference. Might they be useful?

Hmmm, well, here’s something interesting. With one exception, these earliest known ancestors certainly are not English, Welsh or Scots-Irish. They also aren’t German or Dutch.

I attempted to build a tree for Sarah Anna Wilson who was born in 1823 and died in 1858, but without additional information, I quickly ran into too much ambiguity.

Maybe there’s better information in the rest of the GD1 matches’ earliest known ancestors.

These people all look to be…Scandinavian?

Let’s take a look at the Matches Map.

Matches Map

On the matches map, only a few of the 36 GD1 matches filled in the location of their earliest known ancestor. This can be done on either the matches map, or when you complete the earliest known ancestor information.

Exact matches are red, and GD1, 1 step matches, are orange.

All 10 of the GD1 matches that have completed their locations are found in Scandinavia, one in Denmark and Sweden, respectively, with the rest concentrated in Finland.

In fact, the largest cluster anyplace is found in Finland, with a second pronounced cluster along the eastern side of Sweden.

Generally speaking, the green 3-step matches would be “older” or more distant than the yellow 2-step matches that would be older than the orange one-step matches which would be older than the red exact matches.

What Does This Mean?

I’d surely like more data. Scandinavian testers are wonderful about entering their EKA information, as compared to many US testers, but I’d still like to see more. Some show ancestors but no location, and some show nothing evident.

I’m going to dig.

Where Can I Find More Info?

For each person, I’m going to utilize several resources, as follows:

  • Trees on FamilyTreeDNA (please, let there be trees)
  • Earliest known ancestor (EKA)
  • Ancestry/MyHeritage/FamilySearch to extend trees or location locations for listed ancestors
  • Email address on tester’s profile card
  • Google their name, ancestor or email
  • Social media
  • Surnames/locations on their FamilyTreeDNA profile card
  • WikiTree/Geni and other publicly available resources

Even just the email address of a tester can provide me with a country. In this case, Finland. If the tester lives in Finland today, there’s a good chance that their ancestor was from Finland too.

Sometimes the Ancestral Surnames provide locations as well.

Search everyplace.

Create A New Map

Using Google My Maps, a free tool, I created a new map with only the GD1 matches and the location information that I unearthed.

I found at least general (country level) locations for a total of 30 of 36 GD1 matches. Ten are the locations provided by the testers on the Matches Map, but I found an additional 26. All of the locations, with one exception, were found in either Finland or Sweden. One was found in Denmark.

Some locations were the same for multiple testers, but they did not have the same ancestors.

While I’m still missing 6 GD1 match locations, with one exception noted previously, the names of the matches look Scandinavian as well.

This message is loud and clear.

Dorcas’s ancestors were Scandinavian before they came to the US. There’s no question. And likely from Finland.

Thoughts

So, maybe Dorcas really didn’t speak English.

But if she didn’t speak English, how did she communicate with her Scottish or Scots-Irish or maybe Dutch husband? The language of love only suffices under specific circumstances😊

And how did they get to Pennsylvania?

But wait?

Didn’t one of the family histories suggest that Peter Johnson was from Wilmington, Delaware and then from Head of Elk, now Elkton, Maryland?

Weren’t those both Swedish settlements?

Head of Elk, Maryland

Sure enough, Head of Elk, Maryland was settled by Swedish mariners and fishermen from Fort Casimir, Delaware, now New Castle, in 1694 – just 15 miles or so upriver.

Here, moving right to left, we see Fort Casmir, Delaware, then Elkton, Maryland, followed by the location on the border of Maryland and Pennsylvania where Peter Johnson and Mary Polly Philips settled in 1742.

One of those early Johnson books says that Peter Johnson spent some time in Frederick County, Virginia which would be near Winchester, Virginia, halfway between 1742 and 1775 on the map. However, many modern researchers discount that and presume that Virginia was mistaken for Maryland. The 1742 land bordered on and extended into Frederick County, Maryland.

However, since Dorcas Johnson married Jacob Dobkins whose father lived on Holman Creek in Dunmore County in 1775, and Rachel Johnson was supposed to have married a John Dobkins, and, Margaret Johnson married Evan Dobkins, Peter Johnson HAD to have spent at least some time in that location in 1775 if these were his daughters. Those girls were certainly not traveling alone during the Revolutionary War.

By 1780, Peter Johnson and Mary Polly Phillips were in Allegheny County, by Pittsburg where they spent the rest of their lives.

Their daughters had moved on to East Tennessee with their Dobkins husbands, assuming that indeed, Dorcas Johnson is the daughter of Peter Johnson and Mary Polly Phillips.

Conclusions Anyone?

I’m always hesitant to draw conclusions.

However, I would suggest the following:

  • I would expect Scandinavian mitochondrial DNA to be found in a Swedish settlement that also happened to include people from Finland and Denmark.
  • It would be unlikely for Scandinavian mitochondrial DNA to be found in a heavily Scots-Irish and German area such as Cumberland County, PA and Frederick County, MD.
  • We have several triangulated matches between my cousin, Greg, who descends from one of Peter Johnson’s sons and Dorcas Johnson Dobkins’ descendants through multiple children.
  • I match several people autosomally who descend from Peter Johnson and Mary Polly Philips through their other children.
  • Mary Polly Phillips doesn’t sound very Scandinavian. Was her name anglicized?

How Can We Firm This Up?

The best way to verify that Dorcas Johnson descends from Mary Polly Phillips is to test another person who descends through all females to the current generation through a different daughter. If they are sisters, both descending from Mary Polly Phillips, their descendants’ mitochondrial DNA will match very closely if not exactly.

The only other potential daughters are:

  • Rachel who is reported to have married a Dobkins male, possibly John, and maybe moved to Knox County, Indiana.
  • Margaret Johnson married Evan Dobkins, but she isn’t reported as a daughter of Mary Polly Phillips.
  • Rebecca who may have married John Stephens and might have moved to West Virginia.

That’s a whole lot of maybe.

Finding Rebecca and a mitochondrial DNA descendant would be a huge step in the right direction. The only record I can find that might be Rebecca is in December of 1821 when John Stephens’ will is probated in Boone County, KY with wife, Rachel, daughters Salley, Catharine, Rebecca, Mary, and Rachel who is encouraged to never go back to live with John Smith. Wonderful, a Smith – every genealogists nightmare.

If you descend from this couple, PLEASE get in touch with me!

It doesn’t look like this avenue is very promising, so let’s think outside the box and get creative.

Peter Johnson’s Y DNA

Given that Peter Johnson and Mary Polly Phillips were married, they assuredly had to be able to talk, so either she spoke English, or he spoke her Native tongue.

One of the stories about Peter’s family is that he was either Swedish or Dutch, and that his family was from the New Sweden settlement in America.

If this is accurate, then Peter Johnson would have Scandinavian Y and mitochondrial DNA. Since men don’t pass their mitochondrial DNA on to their offspring, that route is not available to us, but what about his Y DNA?

Is there a Y DNA test through a Johnson male descendant of Peter Johnson, and if so, what information does it convey?

Can we use the Y DNA test of a descendant of Peter Johnson to help confirm that Dorcas Johnson is the daughter of Mary Polly Philips? How would that work?

Stay tuned!
