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

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

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

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

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

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

In fact, in order:

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

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

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

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

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

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

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

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

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

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

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

Matching Location at MyHeritage

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

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

AutoClusters

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

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

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

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

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

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

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

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

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

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

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

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

Endogamous Relationships

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

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

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

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

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

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

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

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

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

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

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

However, in these dozen examples:

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

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

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

Furthermore, it can get more complex.

Half Endogamous

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

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

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

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

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

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

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

However, that’s not universally what we see.

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

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

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

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

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

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

Ancestry and Timber

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

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

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

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

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

Endogamous Segments

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

How and why does this happen?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

More, Smaller Segments

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

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

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

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

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

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

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

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

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

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

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

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

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

Endogamy, Segments, and Distant Relationships

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

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

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

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

“Are Your Parents Related?” Tool

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

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

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

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

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

Click on “Are your parents related?”

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

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

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

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

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

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

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

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

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

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

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

Let’s look for more clues.

Surnames

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

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

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

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

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

You can evaluate in either or both of two ways:

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

Here are some examples from our testers.

Jewish – Closest surname matches.

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

Acadian – Closest surname matches.

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

Native American – Closest surname matches.

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

You may recognize these categories of surnames immediately.

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

The most unusual surnames are likely your best bets.

Projects

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

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

Scroll down until you see this image.

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

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

These results are for Muise, an Acadian surname.

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

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

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

Locations

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

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

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

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

Y DNA, Mitochondrial DNA, and Endogamy

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Discover for Y DNA Only

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

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

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

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

You’ll be treated to:

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

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

Endogamy Tools Summary Tables

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

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

Summary of 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.

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

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

How to Download Your DNA Match Lists & Segment Files

If you’ve taken an autosomal DNA test and you’re working to determine how your matches are related to you, meaning which ancestors you share, you’ll want to download your DNA match list.

There are three types of files that you can potentially download from each of the major autosomal DNA testing vendors.

Raw DNA file – If you want to upload your DNA file to another vendor for matching at their site (MyHeritage and FamilyTreeDNA,) you’ll need to download your raw data file from the vendor where you tested. I provided step-by-step instructions for this process at each of the vendors, here.

DNA Segment File – This file contains the segment information with each of your matches, including the start and end locations of your matching segment(s), the total number of matching (shared) centiMorgans (cM) above the vendor’s matching threshold, and sometimes the longest segment.

If you want to sort a spreadsheet to look for all of your matches on specific areas of chromosomes, this is the best way to achieve that goal. I use this information at DNAPainter when painting the segments of matches with whom I can identify a common ancestor.

You may be able to download filtered lists or individual match data as well, as opposed to an entire match list spreadsheet, but the methodology varies at each vendor.

Ancestry does not provide segment information at all. 23and Me combines this information with the next file.

Match List – This file will contain your list of matches along with other information about the matches which you will find genealogically helpful. I find using this file easier than viewing each match separately at the vendors when trying to obtain an overview or when searching for a particular surname in either my match list or their ancestral surnames.

I can also sort by haplogroup, for example, which can sometimes help immensely if that information is available.

Ancestry does not facilitate or allow downloading your match list. 23andMe combines this information with your matching DNA segments in one file.

Here’s a handy-dandy summary by testing vendor.

Vendor Raw DNA File DNA Segment File Match List
23andMe Yes, instructions here Yes, instructions in this article Yes, instructions in this article
FamilyTreeDNA Yes, instructions here Yes, instructions in this article Yes, instructions in this article
MyHeritage Yes, instructions here Yes, instructions in this article Yes, instructions in this article
Ancestry Yes, instructions here No, does not provide No, does not provide

I’ve written step-by-step instructions for how to download your Match List and DNA Segment file(s) at each vendor.

23andMe

Please note that 23and Me is the only vendor to limit your matches, which means you will only receive a file containing:

  • 1500 matches if you tested before the V5 chip, so before August 9, 2017, and have not established communications with matches that would have rolled off of your list otherwise. (I have 1805 matches, so have established contact with 305 that would otherwise have rolled off the end.)
  • 1500 if you tested on the V5 chip, so beginning August 9, 2017, but did not establish communications OR did not purchase the health option, OR did not purchase the yearly membership. If you established communications, those matches won’t roll off, and if you purchase the membership, the match threshold is raised. You may still need to establish contact to keep people from rolling off the larger list as well.
  • 5000-ish (23andMe doesn’t say exactly) if you tested on the V5 chip for BOTH ancestry and healthy AND purchased the yearly membership.

You will only receive match information for people who are listed on your restricted match list, not people who have rolled off as closer matches arrived. Therefore, I encourage you to retain your old match lists because some of your matches will be gone each time you download.

23andMe combines your match list with your segment file.

Sign on and select DNA Relatives on the toolbar.

Next, select “See all relatives.”

Scroll to the very bottom and click on Request DNA Relatives Data Download.

Your file will be prepared, and you’ll receive an email when the file is ready to be downloaded. Mine only took a minute or two, and I simply waited on my 23andMe page until the message appeared.

Save and open the downloaded file, and you’ll see a variety of information about each of your matches, in closest-match-first order, including:

  • Match name
  • Chromosome segment match information, including start and end locations, genetic distance (centiMorgans cMs,) and SNPs
  • Maternal and paternal sides if your parent or parents have tested
  • Number of matching segments
  • Relationship information
  • Birth year
  • Percent shared DNA
  • Haplogroups
  • Notes you’ve made
  • Family surnames
  • Family locations
  • 4 Grandparents’ birth country
  • Family Tree URL, external to 23andMe, if provided by tester

FamilyTreeDNA

At FamilyTreeDNA, your match list and segment information are contained in two separate files.

Sign on and click on Family Finder Matches under Autosomal DNA Results and Tools.

You’ll see your matches. At the top of your match list, on the right side, click on “Export CSV.”

You can select “All Matches” or “Filtered Matches.”

If you haven’t selected a filter, you won’t be able to make that selection. Generally, you want the entire match list.

Your match list will be prepared and downloaded.

You’ll find:

  • Match name
  • Relationship information
  • Shared DNA total
  • Longest segment
  • Linked relationship if you have linked that person to their profile card in your tree
  • Ancestral surnames
  • Haplogroups if tested
  • Notes you’ve made
  • Bucketing – Paternal, maternal, both, none
  • X-Match amount

Note – If you’re a male, valid X matches (meaning matches that are not identical by chance,) will always be on your maternal side because you received your Y chromosome from your father instead of a copy of his X. I wrote about X matching, here.

If your match is a male, an X match will always be through his mother’s line.

Segment information is available in a separate download on the chromosome browser page.

Under Autosomal DNA Results and Tools, click on the Chromosome Browser.

You’ll be able to select people to compare in the chromosome browser, but to download all of your matching segments to all of your matches, click on “Download All Segments.”

If you select people to compare your relationship, and then click on “Download Segments,” you’ll only be downloading the segments for the people you are comparing.

To download all of your segments, be sure the “All” is showing in the link and download before selecting anyone for comparison.

MyHeritage

MyHeritage also provides two separate files for matches and chromosome segment information.

Select DNA matches, then the 3-dot menu, then “Export DNA Matches.”

If you also want your individual segment information for your matches, also order the second file on that menu, “Export shared DNA segment info for shared DNA matches.”.

You’ll see a message that your report is being prepared and will be sent to the email address on file.

If your file doesn’t appear in your email box, check your spam folder.

Your match list provides:

  • Match name
  • Age
  • Country
  • Contact link
  • DNA managed by (if not the tester)
  • Contact link for DNA manager
  • Relationship information
  • Total cM
  • Percent of matching DNA
  • Number of matching segments
  • Largest segment
  • Has tree and tree manager
  • Number of people in their tree
  • Tree link and link to contact tree manager
  • Number of SmartMatches
  • Shared ancestral surnames
  • All ancestral surnames
  • Notes you’ve made
  • Has Theory of Family Relativity

Now that you have these files, what do you do with them?

Evaluating

Is there anything that stands out as remarkable, perhaps that you didn’t know or notice before? Patterns that might be informative?

I had a huge brick wall on my mother’s side that has since fallen, but retrospectively, had I reviewed these lists when that wall was still standing firm, there was a huge hint just waiting for me.

My mother has a very unexpected Acadian line through her great-grandfather, Anthony Lore, so 12.5% of her heritage.

On my match list, I see a large number of French surnames, but I didn’t know of any French ancestors on either side of my tree. Many surnames repeat, such as LeBlanc, d’Entremont (which is really unusual), Landry, and deForest. Why were these people on my match list? This is definitely smoke, and there must be fire someplace, but where?

Looking at the locations associated with these matches’ ancestors would have provided additional clues.

However, simply googling my great-grandfather’s surname in combination with those French surnames I listed above produced these 3 top search results.

Yes, you guessed it. Anthony turned out to be “Antoine” and Lore is spelled in a variety of ways, including Lord. His family is Acadian.

That’s Anthony Lore, which is how he was listed on the death certificate of his son, in the software on my computer, above, and here is Antoine Lore at WikiTree, below.

As you can see, that brick wall falling opened a whole new group of ancestors, and along with it, my appreciation of endogamy😊

Match lists facilitate viewing the big picture and can be a very useful tool for people seeking unknowns or trying to group people together in a variety of ways.

Do you have any brick walls that need to fall?

How can or do you utilize your match lists?

DNA-eXplained Celebrates Tenth Anniversary!

This blog, DNA-eXplained, is celebrating its 10th anniversary today. How time flies!

I never thought for a minute about a 10th anniversary when I launched that first article.

I started blogging to teach people and literally “explain” about genetic genealogy – which is why I selected the name DNA-eXplained. Over time, it has also been nicknamed DNAeXplain, which is fine.

I hoped to be able to answer questions once, with graphics and examples, instead of over and over again off-the-cuff. I needed someplace where people could be referred for answers. Blogging seemed like the perfect medium for achieving exactly that.

Blogs allow writers to publish content attractively and react to changes and announcements quickly.

Blogs encourage readers to subscribe for email delivery or use RSS reader aggregation and can publish to social media.

Content can be located easily using browser searches.

Everything, all content, is indexed and searchable by keyword or phrase.

Blogging certainly seemed like the right solution. Still, I was hesitant.

I vividly remember working at my desk that day, a different desk in a different location, and anguishing before pressing the “publish” button that first time. Was I really, REALLY sure? I had the sense that I was sitting in one of those life-defining fork-in-the-road moments and once embarked upon, there would be no turning back.

I’m so glad I closed my eyes and pushed that button!

I knew we were going to be in for an incredible journey. Of course, I had no idea where that roller coaster ride was going, but we would be riding together, regardless. What a journey it has been!

A decade later, I’ve had the opportunity to meet and become friends with so many of you, both online and in person. I’ve met countless cousins I never knew I had, thanks to various blog articles, including the 52 Ancestors series which has turned out to be 365 and counting.

I am incredibly grateful for this opportunity! I thought I was giving to others, yet I’ve been greatly enriched by this experience and all of you.

So much has changed in all of our lives.

Looking Back

Today, as I look back at that very short first article, I can’t help but think just how unbelievably far we’ve come.

There was one Y and mitochondrial DNA testing vendor in 2012, FamilyTreeDNA, and that’s still the case today.

There were three autosomal testing companies, 23andMe, FamilyTreeDNA, and Ancestry, in addition to the Genographic Project, which was sunset in 2019 after an amazing 15-year run. GEDmatch was two years old in 2012 and had been formed to fill the need for advanced autosomal matching tools. In 2016, MyHeritage joined the autosomal testing market. All of those companies have since been acquired.

In 2012, FamilyTreeDNA broke ground by accepting uploaded DNA files from other vendors. Autosomal DNA tests cost about $300 although prices were dropping. I don’t anticipate prices dropping much further now, because companies have to maintain a reasonable profit margin to stay in business.

In 2013, when DNA-eXplained celebrated its first anniversary, I had published 162 articles.

That first year was VERY busy with lots of innovation occurring in the industry. You can read my end-of-year article, 2012 Top 10 Genetic Genealogy Happenings if you’d like to reminisce a bit. For comparison, here’s my Genetic Genealogy at 20 Years summary.

The World is Our Oyster

In the past decade, I’ve penned articles in a wide variety of locations, in several countries, on 5 continents.

I’ve written in my offices, of course, but also in cars, on buses, trains, and planes. I’ve crafted several articles on ships while cruising. In fact, writing is one of my favorite “sea-day” things to do, often sitting on deck if it’s a nice day.

I’ve written in cemeteries, which shouldn’t surprise you, on the hood of my car, and cross-legged on the floor at innumerable conferences.

I’ve composed at picnic tables and in countless hotel lobbies, libraries, laboratories, restaurants, and coffee shops. And, in at least 3 castles.

I’ve written while on archaeology digs, balancing my laptop on my knees while sitting on an inverted bucket, trying to keep dirt, sand, and ever-present insects away.

I’ve even written in hospitals, both as a visitor and a patient. Yea, I might not have told you about that.

I’ve pretty much taken you with me everyplace I’ve gone for the past decade. And we are no place near finished!

Today

This article is number 1531 which means I’ve published an article every 2.3 days for a decade. Truthfully, I’m stunned. I had no idea that I have been that prolific. I never have writer’s block. In fact, I have the opposite problem. So many wonderful topics to write about and never enough time.

A huge, HUGE thank you to all of my readers. Writers don’t write if people don’t read!

DNA-eXplained has received millions and millions of views and is very popular, thanks to all of you.

There have been more than 48,000 comments, 4,800 a year or about 13 each day, and yes, I read every single one before approving it for publication.

Akismet, my spam blocker only reports for 45 months, but in that time alone, there have been about 100,000 attempted SPAM comments. That equates to about 75 each day and THANK GOODNESS I don’t have to deal with those.

WordPress doesn’t count “pages,” as such, but if my articles average 10 pages each, and each page averages 500 words, then we’re looking at someplace between 7 and 8 million words. That’s 13 times the size of War and Peace😊. Not only do I write each article, but I proofread it several times too.

Peering Into the Future

Genetic genealogy as a whole continues to produce the unexpected and solve mysteries.

Tools like triangulation in general, Family Matching at FamilyTreeDNA, genetic trees at 23andMe, Theories of Family Relativity at MyHeritage, and ThruLines at Ancestry have provided hints and tools to both suggest and confirm relationships and break through brick walls.

Ethnicity chromosome painting at both 23andMe and FamilyTreeDNA help unravel ancestral mysteries, especially for people with combinations of fundamentally different ancestries, as does Genetic Communities at Ancestry and Genetic Groups at MyHeritage.

Third-party tools that we love today weren’t even a twinkle in a developer’s eye in 2012. Products like DNAPainter, Genetic Affairs, and DNAGedcom pick up where the vendors leave off and are widely utilized by genealogists.

I hope that all of our vendors continue to invest in product development and provide the genetic genealogy community with new and innovative tools that assist us with breaking down those pesky brick walls.

Primarily, though, I hope you continue to enjoy your genealogy journey and make steady progress, with a rocket boost from genetic testing.

The vendors can provide wonderful tools, but it’s up to us to use them consistently, wringing out every possible drop. Don’t neglect paternal (male surname) Y DNA and matrilineal mitochondrial DNA testing for people who carry those important lines for your ancestors. All 4 kinds of DNA have a very specific and unique genealogical use.

I encourage you to test every relative you can and check their and your results often. New people test every single day. You never know where that critical piece of information will come from, or when that essential puzzle piece will drop into place.

Be sure to upload to both FamilyTreeDNA and MyHeritage (plus GEDMatch) so you are in the database of all the vendors. (Instructions here.) Fate favors the prepared.

Thank You!!

Thank you from the bottom of my heart for supporting me by reading and sharing my articles with your friends, organizations, and family members, by purchasing through the affiliate links, by buying my book, and by graciously sharing your own experiences.

Thank you for your suggestions and questions which plant the seeds of new articles and improvements.

I hope you’ve made progress with your research, unraveled some thorny knots, and that you’ve enjoyed this decade as much as I have. Tell me in the comments what you enjoyed the most or found most useful?

Here’s to another wonderful 10 years together!

Find a Grave (Owned by Ancestry), Seriously, JUST STOP Incentivizing the Creation of Memorials of the Recently Deceased

I’ve been horrified, as has any sentient being, about the massacre in Uvalde, Texas.

I’ve also been increasingly furious these past few days because the practice of awarding “points” by Find a Grave, owned by Ancestry, to people who create memorials is making an already horrific situation much worse for traumatized families whose members perished.

THESE CHILDREN AREN’T EVEN BURIED, yet a non-family member rushed to create memorials for them, including photos and other family details lifted from news articles and other sources! We won’t even mention the copyright violations that Ancestry/Find a Grave consistently chooses to ignore.

This vampiristic death-gathering and memorial-creating behavior isn’t limited to the Uvalde massacre, it’s Buffalo and other victims of mass killings in addition to people who die of natural causes every day.

The same thing happened with one of my immediate family members a few years ago, and I still remember the shock of discovering her via a “hint” in the midst of grief.

Before I continue, I’d encourage you to read Judy Russell’s blog article, Ancestry, this one’s on you, but come back here when you’re done. Judy is on FIRE about this one, and with good reason.

Ancestry’s Failed Policy

Ancestry’s supposed policy of showing limited information about a memorial unless the creator is an immediate family member obviously had a major fail given that Judy was able to take screenshots of the memorial of this recently murdered child.

After a rather loud and persistent outcry from the community, back in January Find a Grave decided to redact some information for 3 months after a death. Yet, the memorial remains in place for the family to find. Ancestry does NOT prevent the creation of these memorials for bounty points.

This situation should never have happened in the first place and has been ongoing with incredible foot-dragging by Ancestry FOR YEARS! It’s just in our faces again with the Uvalde and other recent high-profile mass murders.

Even with the photo and some information hidden, for now, the Uvalde victims’ memorials are still listed. The one above is the same child’s memorial as in Judy’s article.

Even after eventually transferring the memorial to a family member, the original creator is always still listed. Unfortunately, this practice of awarding points and forever listing the “creator” by Ancestry encourages and incentivizes “trophy hunting.”

Here’s an example from one of my immediate family members.

You can then click on the name of the creator or the “maintainer,” which is me in this case, and see their stats. Here’s mine.

Notice that in Judy’s original screenshot, you could see the Find A Grave identity of the person who created that child’s memorial. However, Find a Grave has chosen to “protect” that person in the redacted version by not showing the creator’s identity. So we don’t know who collected that bounty point.

This is not a new issue. Ancestry/Find a Grave has not and is not acting expediently to resolve the situation. In fact, the “situation” doesn’t have to exist at all.

Take a look at this complaint board about Find a Grave. These issues pepper the genealogical community on social media, day after day after day.

Why Is This Happening?

This occurs because Ancestry displays the number of memorials created by volunteers. Some people spend their time finding obituaries and death announcements and creating memorials for people as soon as they die in order to rack up points, like a game.

The problem is that finding your loved one’s memorial, often with incorrect information, created by a stranger is unexpectedly jarring, at best. Especially to discover that your family member was only a trophy harvest whose memorial was created hours after they died. Then, having to ask (sometimes beg an unresponsive person) for the transfer of their memorial to you, only to have the creator’s name forever associated with the memorial adds insult to injury.

I’m not referring here to a volunteer who lives locally and “takes care” of local cemeteries, like the person who created memorials for my parents months after they were buried, not hours after they died. Most of those people are respectful, kind, and pleasant to deal with. They provide their services out of the kindness of their heart AFTER giving the family a respectable amount of time. Those ARE NOT the people I’m referring to.

Those lovely local volunteers aren’t the mega-harvester people searching online funeral home listings morning and night for new points to score. That is NOT a service to anyone except themselves, and oh yea, Find a Grave/Ancestry who can then serve up hints to Ancestry subscribers and garner page views.

Ancestry clearly wants to keep those harvesters engaged but to the detriment of the actual genealogists who subscribe to Ancestry’s services. That’s a mighty high price leveraged on the backs of their customers. And let’s face it, sooner or later, everyone’s parents, siblings, or (God forbid), children pass away. Ancestry is rewarding people to further torture the grieving. Every grieving person needs a respectable amount of time and space. Ancestry, of all companies, should be sensitive to this.

What Needs to Be Done?

I’m not privy to any inside information, but I believe that originally Find a Grave, before it was purchased by Ancestry, began listing memorials and other stats to encourage volunteers to document and photograph cemeteries to assist genealogists. That was the original purpose.

However, that purpose has morphed into something very different. Ancestry has the agency, and responsibility to put the brakes on.

Ancestry needs to:

  1. Stop awarding points like trophies, at least publicly.
  2. Remove the name of the original creator when the memorial is transferred to a family member.
  3. Prevent anyone except close family members from creating memorials for minimally 90 days and I’d suggest a year.

I wasn’t done with my mother’s estate for at least a year and wasn’t ready to deal with seeing her photo and obituary online until then.

And if that was my child, OMG.

Who in their right mind would think that entering those massacred children into Find a Grave immediately was acceptable by any criteria? Any standards of decency? And why would Find a Grave tolerate this for even a minute? Death is traumatic for family members under the “best” of circumstances and it only goes downhill from there.

And this is clearly the worse of circumstances.

While the individuals who created those memorials before the bodies were even cold were insensitive, and that’s the best spin I can put on it, Ancestry is the only one who can, should, and has the responsibility to stop this. And they have, so far, been unwilling.

It’s time for every single one of us to speak up. Bloggers and influences as well as the rest of Ancestry’s customers. We can all be influencers.

Use Your Outside Voice

Ok, bloggers and social media people – use your voices. We have even more influence cumulatively, together, as a chorus, than individually.

I do need to provide a word of warning though, especially to bloggers and other professionals.

Ancestry is punitive if you don’t always write positively about them. They will pull your affiliate account if you have one. They will exclude you from influencer calls, meetings, and related events at conferences. I’m guessing Judy and I will be enjoying snacks in the restaurant while those meetings are taking place. I encourage you to join us. It’s worth it to do the right thing.

You don’t need to be a blogger to have an influence. Everyone has a voice. Here are several things everyone can do.

Ancestry’s CEO

Deborah Liu was named Ancestry’s CEO in February 2021. She can fix this with one call or email.

This would be a good Twitter thread to reply to:

Based on Deborah’s social media photos, she has children. Ask her how she would feel if her children were massacred, and some unknown trophy hunter created their memorial as soon as their name was available. Would she feel violated? Crushed? Robbed of the opportunity to provide that caring act for her precious family member when she was ready?

God forbid this would ever happen to Deborah or her family, but if it did, this problem would be remedied in about 30 seconds.

Deborah may be “mourning with them,” but she is increasing the grief of countless people by failing to remediate Ancestry’s company policy. Furthermore, she, assuredly, is not following the Golden Rule by “doing unto others.” As if just doing the “right thing” isn’t enough reason alone.

Here’s the Biblical reference, if she needs it:

Matthew 7:12 (International Version), “So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets.”

Perhaps Deborah didn’t know before, but let’s make absolutely positively sure she knows now!

Other Resources

Here’s a list of other places you can place comments and make yourself heard!

Let’s be that squeaky wheel and get results. Be respectful, but be sure to remind Ancestry that you are a PAYING customer when you call.

Ancestry, it’s way past time to step up.

Ancestry’s SideView™ – Dividing Your Ethnicity in Two

Recently, Ancestry introduced a new view of your ethnicity called SideView™. In a nutshell, AncestryDNA uses your DNA matches to attempt to divide your ethnicity into regions inherited from Parent 1 and Parent 2.

Based on your matches and the common DNA they share with you, Ancestry strives to divide your ethnicity into parental “sides,” although Ancestry can’t tell you which side is maternal and which side is paternal.

Even though Ancestry can’t tell you which side is which parent, there are tricks that might help you do just that.

Ethnicity

Before we look at SideView, let’s have a quick review of ethnicity estimates and how they do and don’t work.

Every vendor creates their own proprietary mathematical algorithm to determine their customers’ ethnicity or population percentages based on their own customer database and other resources.

“Country” boundaries change and people migrate. The article, Making Sense of Ethnicity Updates may be helpful.

If you haven’t done so, create a spreadsheet or chart identifying the amount of DNA you would inherit from each ancestor if exactly 50% of each ancestor’s DNA was passed down in each generation. Your spreadsheet may/will help you identify which “side” belongs to which parent. I provided instructions for calculating your expected ethnicity percentages based on your genealogy in the article, Concepts – Calculating Ethnicity Percentages.

My Genealogy

I’ve updated my genealogy totals slightly since that 2017 article because I’ve been able to push some of those lines back in time, either genealogically, via Big-Y or full sequence mitochondrial DNA testing and matching, or a combination of both.

Here’s an updated chart. I’ve included the last two ethnicity percentage results from each vendor except MyHeritage because their ethnicity results have remained the same for several years although they released Genetic Groups to complement ethnicity in 2020.

I’ve clustered geographies in regions because the vendors measure locations differently. Locations sometimes change within the same vendor with different releases.

The earlier “Unknown” genealogy category is gone now because I’ve been able to assign those ancestors to a geographic region if not an exact “country.”

The Genealogy Percent column, with a header and totals in yellow, details the geographic source for each of my 64 great-great-great-great-grandparents who each contributed approximately 1.5625% of my DNA. Of course, we know that DNA isn’t divided exactly in half in each generation, and I possibly inherited none of the DNA of some of those people and more than 1.5625% from others. Regardless, this is the best measuring stick of what I should expect and a way to determine if my ethnicity results are in the right ballpark.

The yellow cells in the vendor column totals reflect the “best fit” for my known genealogy percentages when compared against the expected percentages. In the Native grouping, vendors receive a yellow cell for identifying that heritage.

OK, now let’s take a look at Ancestry’s new SideView.

Finding SideView

At Ancestry, your ethnicity estimate, as well as your new SideView results, are found in the DNA Story section of your DNA Results Summary tab.

Ancestry does update your ethnicity estimate from time to time, so yours may have changed since you last viewed your results.

Ideally, if exactly half of the DNA of each ancestor was passed down in each generation, then I would have the amount of DNA shown in my personal chart, assuming my genealogy is accurate with no adoptions or unexpected parent events.

Also ideally, I would show exactly half of each of my parent’s ethnicity.

But that’s not how it works. While we do inherit half of our DNA from each parent, they can randomly give us all of a segment of DNA from one ancestor and not any of a segment of DNA from a different ancestor.

I wrote about how DNA is passed to children in the article, Ancestral DNA Percentages – How Much of Them is in You?. This explains how and why you might not inherit the exact amount of a specific ethnicity you would expect. Of course, that combined with each vendor’s different algorithms may produce results that surprise you, although the discrepancy should be relatively small.

Keep in mind how ethnicity inheritance works as you view your ethnicity results, including SideView.

SideView Results

Here are my Sideview results.

Remember, we don’t know which parent is “1” and which is “2.” Click on “How we identify this” to learn about how SideView works.

Here’s a more detailed description along with some nice graphics.

Analyzing My Results

SideView appears right beside your ethnicity map, so be sure to consult that map. Note that regions reflect populations, not necessarily countries as boundaries are drawn today.

The first thing I noticed is that my significant Dutch heritage, along with my French is missing in my ethnicity results as well as on the map.

How is this possible?

The arrows point to the Netherlands and France. These are important pieces of my ancestry on my Mother’s side. Mom was 25% Dutch so I should be about 12.5%. My maternal side genealogical breakdown is shown in the chart below.

Mom % I Should Inherit From Mom
German 50 25
Dutch 25 12.5
French/Acadian 12.5 6.25
England 12.5 6.25
Native ~2 in the Acadian line ~1

Of course, my Native American is also missing at Ancestry, even though the other three major vendors identify those segments. The two vendors who paint ethnicity by segment, 23andMe and FamilyTreeDNA report Native on the same segment on my chromosome 1, so it’s unlikely that both of those vendors are in error in exactly the same way.

While Native is critically important to my genealogy, it is a small percentage. Missing a small percentage, while frustrating, is more understandable than missing a larger percentage.

My Dutch ancestors at 12.5% and French at 6.25% are not trivial and together comprise more than one-third of my mother’s heritage and more than one-sixth of mine. And yes, in case you’re wondering, I do match many other people who descend from these same ancestors so it’s not a mistaken or misidentified ancestor issue.

My father was kind of a colonial mutt. Scottish, Irish, and English with a small smattering of African and Native along with 1.5% Scandinavian/Nordic. The African in the later versions tends to show as Middle Eastern or North African, or doesn’t show at all, but that segment with a small Native one cluster together on the same chromosome. I also match other people who are Native/African on those segments as well.

However, given that neither of those ethnicities appear at Ancestry, we don’t have those to work with, nor do we have specific segment information.

Let’s work with what we do have.

View Breakdown

I wish Ancestry did not say “Now, you can see which ethnicities you inherited from each parent,” because while that’s the goal, it isn’t always the case. Lots of people will simply accept that statement at face value.

Click on View breakdown.

You’ll see your results broken into two sides with the reported regions noted at the bottom. All regions are showing in the circle by default.

To see how this works, click on any single or combination of regions.

Determining Sides

What can we do to determine which side is which parent?

Let’s start with ethnicities or regions which should be unique to one parent and not the other.

I clicked on both Norway and Sweden/Denmark since I know that one couple on my father’s side is Scandinavian/Nordic, but I discovered that Ancestry assigned pieces of those regions to both Parent 1 and Parent 2.

I’m positive that my mother did not have any ancestors in the past 6 generations and significantly further back that were Scandinavian or Nordic, BUT, Germany and the Netherlands both border those regions. People traveled, wars happened and populations as a whole mixed, so while I’m confident of my genealogy, this actual ethnicity may be accurate even though it does not reflect genealogical locations. It may well reflect populations and admixture.

What I am sure of is that I can’t use these particular regions to identify which side is maternal or paternal.

Detailed Comparison

Let’s look at the detailed comparison you’ll see by scrolling down.

Can I identify any of these regions as solely connected with only one parent?

Yes, I can. Ancestry has assigned Germanic Europe to only one parent, and Mom is 50% German, so Parent 1 has to be Mother. I should expect to be assigned roughly half of what my mother has – so about 25% Germanic.

Mother has no Irish, so Ireland has to be Dad, which also correlates to known genealogy.

However, the rest of the ethnicity results are questionable, including Mom’s missing Dutch and her missing England and Northwest Europe which should total in the neighborhood of 37.5%. I would be expected to inherit about 18.75% of that from her. Where is it?

No Segments

I very much wish Ancestry provided segment information.

Using segment matching information from the other three vendors, including ethnicity segment information from both 23andMe and FamilyTreeDNA, I’ve painted my segments at DNAPainter, so I know which ancestors or ancestral lines contributed which DNA segments.

If Ancestry, provided users with segment information, I could determine which ethnicities they have attributed to which ancestors and maybe unravel why.

Another Possible Clue

There is one additional way I might be able to figure out where Ancestry attributed Mom’s Dutch and French heritage.

Given that I know which of my closest matches are maternal and paternal, I can utilize shared matching plus shared ethnicity to look for similarities. Just click on the match with someone, then on the Ethnicity tab.

The closest match on my mother’s side is my first cousin who also descends from my maternal grandparents. My cousin’s relevant parent should have roughly the same amount of the same ethnicities as my Mom since they were siblings, taking into account that not all of our ancestors’ DNA is passed in exactly half and siblings, unless they are identical twins, don’t inherit all of the same DNA from their parents. Of course, that means my first cousin should share roughly the same amount of DNA/ethnicity from our common grandparents as I do.

My cousin’s other parent is European with what appears to be a significant number of German ancestors, so we need to take that into account when viewing my cousin’s shared ethnicity comparison with me, above.

I can see that my cousin has 4% French and 1% Native, but that percentage might have been contributed by their other parent, especially since there is a French surname in that line.

If my cousin’s other parent had been African or Asian or an ethnicity that is different from the ethnicity of our shared line, it would be easier to compare our results meaningfully.

In this case, the shared match ethnicity comparison did not help, but your mileage may vary based on your unique circumstances.

Assign the Parent

If you are fortunate enough to be able to determine which parent is which, you can assign Parent 1 and 2 as maternal or paternal at Ancestry by clicking on the “Edit parents” icon at top right on the Detailed Comparison page.

I selected side 1 as Maternal based on the 35% Germanic Europe which is very clearly my mother’s side.

What I wish we could do, but we can’t, is to explain why we disagree with some portion of an assigned ethnicity. Ancestry does have my tree and I do have Thrulines from these ancestors, so the information is available for comparison should Ancestry choose to utilize that resource.

You can undo your selections by selecting “Back” or click on “Sounds good.”

I initially clicked on “Sounds good,” even though that bothers me. I hope that I’m not confirming something that’s incorrect, given my Mother’s missing Dutch and French, and that I’m not going to make *something* worse in the future by baking in bad ingredients. I’m not comfortable confirming something that’s significantly wrong. On the other hand, Parent 1 is clearly my mother, so I’m conflicted and I really don’t know exactly what I’m confirming to Ancestry.

In other words, we don’t know what Ancestry is doing under the hood with this information, if anything, other than labeling your sides.

Ultimately, I clicked “Back”, at least for now, to leave my sides unassigned until there is some benefit to me to identify the parental sides and I know I’m not confirming something that shouldn’t be confirmed. In other words, I know which parent is which, but I do NOT want to confirm that these ethnicities are fundamentally accurately assigned, because they are not.

Does Testing Your Parents Make a Difference?

If you’re wondering if testing your parents makes a difference with SideView predictions, it does not.

Ancestry is NOT utilizing your parents’ DNA for SideView ethnicity division, even if your parent or parents have tested, which Ancestry confirms in their documentation.

If you’re wondering why Ancestry doesn’t use your parent’s DNA to improve your SideView results, remember that someone who matches you at the parent/child level can be either your parent or your child. Often trees are either absent or incorrect, so Ancestry cannot simply assume anything.

Benefits of SideView?

What do you think?

Is there a benefit to SideView or is it simply interesting window dressing?

Are your SideView results accurate?

Do you feel that Sideview is accurate enough to be genealogically useful?

Are you able to utilize Sideview for your genealogy? If so, how?

Ancestry Only Shows Shared Matches of 20 cM and Greater – What That Means & Why It Matters

Recently, I’ve noticed an uptick in confused people who’ve taken Ancestry’s DNA test.

They are using shared matches, which is a great tool and exactly what they should be doing, but they become confused when no shared matches appear with some specific people.

This is especially perplexing when they know through information sharing or because they manage multiple DNA kits that those two people who both match them actually do share DNA and match each other, meaning they “should” appear on a shared match list. Or worse, yet, conflicting match information is displayed, with one person showing the shared match, but the other person reciprocally does not.

What gives?

That’s exactly what this article addresses. It’s not quite as simple as it sounds, but it’s certainly easier once you understand.

What Are Matches and Shared Matches?

Matches occur when two people match each other. From your perspective as a DNA tester, matches are people who have taken DNA tests and appear on your match list because you share some level of DNA equal to or greater than the match threshold of the vendor in question.

At Ancestry, that minimum matching threshold is 8 cM (centimorgans) of matching DNA.

Individual matches are always one-to-one. Your match list is a list of people who all match you.

So, you match person 1, and you match person 2, individually.

Your matches may or may not also match each other. If they do match each other in addition to matching you, that’s a shared match which is a hint as to a potential common ancestor between all three people.

Shared matches are a list of people who match you PLUS any one other match on your list. In other words, shared matches are three-way matches.

In the diagram above, you can see that you match Match 1 and you also match Match 2. In this case, Match 1 and Match 2 also match each other, so all three of you match each other, but not necessarily on the same segment. Therefore, you’re all three shared matches, as shown in the center of the three circles.

Viewing Shared Matches

To view a list of people who match you and Match 1, you would request shared matches with Match 1 by clicking on “View Match” or “Learn More” on your match list, then on “Shared Matches” on the next screen.

The resulting shared match list consist of people who match you AND Match 1, both. It’s easy to make assumptions about why you have shared matches, but don’t.

Shared Matches are Hints

A shared match CAN mean:

  • That all three people share a common ancestral line.
  • You share a common ancestor with Match 1 and Match 2, but Match 1 and 2 match each other because they share an entirely different ancestor.
  • You match Match 1 because you share DNA from Ancestor A and you match Match 2 because you share DNA from Ancestor B. Match 1 and 2 match each other either because they share one or both of those common ancestors.
  • Match 1 and Match 2 might match because Match 1 and Match 2 share an ancestor that isn’t related to you.
  • That one (or more) of the matches is identical by chance, meaning the DNA combined from two parents in a random way that just happens to match with someone else.

Shared matches are great hints to be sifted for relevance. The operative word here is hint.

What If We Don’t Have Shared Matches?

Conversely, NOT having a shared match doesn’t mean you don’t share a common ancestor.

Sorry about the triple negative. Let me say that another way, because this is important.

Even though you and someone else aren’t on a shared match list, you might still share DNA and you may share a common ancestor, whether you share their DNA or not.

Ancestry’s shared matches work differently than shared matches at other vendors. Before we discuss that, let’s talk about why shared matches are important.

Why Do Shared Matches Matter Anyway?

Matches and shared matches are how genealogists perform two critically important functions:

  • Verifying “known” ancestors. Sometimes paper trails aren’t accurate and certainly, neither are trees.
  • Identifying unknown ancestors. Looking for common families among shared DNA matches is a HUGE hint when tracking down those pesky unknown ancestors.

I wrote about shared matches, here, when Ancestry purged segments under 8 cM, but I think the message about the limitations of shared matches and how the process actually works deserves its own article, especially for new users. Shared matches and segment cM numbers can be quite confusing, but they don’t need to be.

I wrote an article titled DNA Beginnings: Matching at Ancestry and What It Means that includes lots of useful information.

Ok, now let’s look specifically at using shared matches and why sometimes shared matches just don’t seem to make sense.

Matches

By far, the majority of your matches at any vendor will be more distant matches. That’s because you have thousands of distant relatives, most of whom you don’t know (yet).

You’ll only have a few closer relatives.

At Ancestry, I have 102,000+ total matches, of which more than 97,000 are distant matches. Based on these numbers, keep in mind that about 95.74% of my matches are distant, meaning 20 cM or below, and yours probably are too. You’ll need that number later.

Note that 20 cM is Ancestry’s threshold between close matches and distant matches.

That’s about exactly where you’d expect, on average, to see a 20 cM match – generally at or further back than 4th cousins. 20 cM is roughly the 4th to 6th cousin level.

Of course, you won’t match most of your 5th cousins at all, yet you’ll match some with more than 20 cM. That’s just the roll of the genetic dice.

Closer ancestors (meaning closer matches) is also the area of genealogy where much of the lower-hanging fruit has been plucked.

In my case, the closest unknown ancestor in my tree occurs at the 6th generation level and I have 5 or 6 missing sixth-generation ancestors – all females with no surnames. Two have no names at all.

How Much DNA Do Cousins Share?

One of my priorities as a genealogist is to identify those unknown people, which is why matches, and shared matching at that level are critical for me.

Ancestry tells me that this 20 cM match is likely my 4th-6th cousin.

At DNAPainter, in the Shared cM Tool, you can enter the total cM number of a match, which is the total amount of DNA that you share after Ancestry’s Timber algorithm has been applied. The range of relationship probabilities for 20 cM is shown below.

For a total match of 20 cM with another individual, several relationships ranging between half 3C2R/3C3R and 8th cousins are the most probable relationships at 58%.

For the record, this is total cM, which does not necessarily mean one segment. Ancestry reports the number of segments, but Ancestry does not show you the segment locations, nor do they have a chromosome browser. Without a chromosome browser, you have no way of determining whether or not you match with shared matches on the same segment(s). In other words, there is no triangulation at Ancestry, meaning confirmation of a specific shared DNA segment descended from a common ancestor. You can find triangulation resources, here.

Close Matches

The best way to figure out how you are related to closer matches (assuming you don’t already know them and Ancestry has not found a common ancestor) is using shared matches. Hopefully, you will share matches with people you do know or with whom you’ve already identified your common ancestor.

One of my relatively close DNA matches at Ancestry is Lonnie. I don’t know Lonnie, but it looks like I should because he’s probably a 1st or 2nd cousin. We share 357 cM of DNA over 20 segments.

I thought I knew all of my 1st and 2nd cousins. Let’s see if I can figure out how I’m related to Lonnie.

By clicking on Lonnie’s name on my match list, then on Shared Matches, I can determine that Lonnie and I connect through my Estes and Vannoy lines based on who we both match, which means that our common ancestor is either my paternal grandfather or my great-grandparents, Lazarus Estes and Elizabeth Vannoy.

You can see the notes I’ve made about these matches I share with Lonnie.

Viewing Lonnie’s unlinked tree verifies the ancestral line that shared matches suggest. An unlinked tree means that Lonnie has not linked his DNA test to himself in his tree. Since Ancestry doesn’t know who he is in the tree, they can’t find a common ancestor for me and Lonnie. However, I can by viewing his tree.

Our common ancestor is Lazarus Estes and his wife, Elizabeth Vannoy. Therefore, Lonnie is my 2nd cousin.

That wasn’t difficult, in part because I had already worked on the genealogy of our common matches and Lonnie had a small unlinked tree where I could confirm our common ancestor.

Now let’s move to more distant, not-so-easy matches.

Distant Matches

I’ve spent a lot of time over the years identifying common ancestors with my matches.

When I make that connection, whether or not Ancestry has been able to identify our common ancestor, I make notes about common ancestors and anything else that seems relevant. Notes very conveniently show on my match list so I don’t need to open each match to see how we are related.

Ancestry does identify potential common ancestors using ThruLines. Note the word potential. Ancestry compares the trees of you and your matches searching for common ancestors and suggests connections. It’s up to you to verify. ThruLines are hints, not gospel. Additionally, you may have multiple ancestral links to your matches. Ancestry can only work with the fact that you have a DNA match with someone AND the user-provided trees of your matches.

Ancestry’s ThruLines only reach back a maximum of 7 generations to suggest common ancestors. At 7 generations distance, you’d be a 5th cousin to a descendant who is also 7 generations downstream from that ancestor.

The information from DNAPainter, who utilizes the Shared CM Project compiled data shows that the most likely amount of shared DNA for 5th cousins, is, you’ve guessed it – 20 cM.

Jacob Dobkins is my 7th generation ancestor. I have ThruLines for him and his wife, but not for their parents who are one generation too distant for ThruLines. I’d LOVE to see Ancestry extend ThruLines another 2 or 3 generations.

ThruLines matches me with people who descend from Jacob through his other children. Other children are important because the only ancestors you share with those people are (presumably) that ancestral couple.

Matches with Jacob’s descendants range from 8 cM (the smallest amount Ancestry reports) to 32 cM.

Here’s an example.

Ancestry displays some shared matches with all of your matches, regardless of the size of your match to that person. However, Ancestry ONLY shows shared matches to a third person if you share more than 20 cM of DNA with that third person.

For example, I match KO with 8 cM of DNA. Ancestry shows my shared matches with KO, below.

I only have 3 shared matches with KO. I only match KO at 8 cM, but I match our shared matches at 39, 31 and 21 cM, respectively.

Ancestry does NOT show shared matches below 20 cM, so it’s unknown how many additional shared matches KO and I actually have if shared matches less than 20 cM were displayed.

Perspective is Critical

Whether you see a shared match or not is sometimes a matter of perspective, meaning which of two people you request shared matches with.

In this case, I requested shared matches with KO. I only share 8 cM of DNA with KO, but that doesn’t matter. The amount of DNA you share with the person you’re requesting shared matches with is irrelevant.

Ancestry’s Shared Matches with KO include Ker

I will see shared matches with KO to anyone we mutually share as matches above 20 cM, including Ker.

If I request shared matches with Ker, with whom I share 39 cM of DNA, I will see all of our mutual matches at 20 cM (or greater) of DNA. However, that does NOT include KO because I only share 8 cM of DNA with KO.

This restriction applies regardless of how much DNA KO and Ker share, which is an unknown to me of course.

Ancestry’s Shared Matches with Ker does NOT include KO

Nothing has changed between these matches, yet KO does not appear on my shared matches list with Ker when I request shared matches with Ker.

I still share 8 cM with KO and 39 cM with Ker. KO and Ker still both match each other. The only difference is that Ker shows up on my shared match list with KO because I share more than 20 cM with Ker. However, when I request a match list with Ker, KO does NOT appear because I only share 8 cM with KO.

This is the source of the confusion and often, why people disagree about shared matches. It’s kind of a “now you see it, now you don’t” situation.

If a person shows as a shared match depends on:

  1. Whether the third person actually does share DNA with the tester and the person they’ve asked for shared matches with
  2. Whether the third person shares 20 cM DNA or more with the tester, the person requesting the shared match list with one of their matches

Whether someone appears on a shared match list can literally be a matter of perspective unless the match and the shared matches all match the tester at 20 cM or larger.

Another Example

Let’s look at a larger match to a descendant of the same ancestor.

I share exactly 20 cM with Joyce, my 5C1R.

Viewing my shared matches with Joyce, I match 50 other people that she matches as well.

I only share 25 cM of DNA with the smallest match with Joyce. Apparently, there are no matches with Joyce with whom I share between 20 and 25 cM of DNA.

Bottom Line

Here’s the bottom line.

Ancestry NEVER shows any shared matches below 20 cM from the perspective of the tester, meaning people who match you and someone else, both.

If you recall our earlier math, that means that approximately 95.74% of my shared matches aren’t shown.

This puts shared matches in a different perspective because now I realize just how many matches I’m not seeing.

Why is This Confusing?

If you aren’t aware of this shared match limitation, and that a majority of your shared matches are actually below 20 cM, you may interpret shared match results to mean you actually DON’T share specific matches with that other person. That isn’t necessarily true, as we saw above with KO and Ker.

Furthermore, let’s say you manage your DNA kit plus 3 more, A, B and C. Because you manage all 4 kits, that means you can see the results for all 4 people.

  • A – 10 cM
  • B – 20 cM
  • C – 40 cM

From the perspective of YOUR kit, you will see some shared matches FOR all of those matches.

What you won’t see is shared matches if you don’t match the shared match (third person) at 20 cM or greater.

Always remember, shared match information at Ancestry is ALWAYS from the perspective of your DNA kit combined with the person with whom you request the match.

I’ve put this information in a grid because that’s how I make sense of things like this.

Here are your matches. When you click on shared matches with person A who you match at 10 cM, you’ll see both person B and person C as shared matches since you match both of those people at 20 cM or larger. You WILL see 20 cM shared matches, but you will not see 19 cM shared matches.

When you request shared matches for A, you will see both B and C.

When you request shared matches with kits B and C, you will not see A because you only match them at 10 cM.

However, from the perspective of DNA kits A, B and C, shared matches look different.

Let’s look at shared matches from the perspective of Kits A, B and C.

Kit A matches you, Kit B and C, but can only see Kit B as a shared match because matches with you and Kit C are under 20 cM.

Kit B doesn’t match C at all, so they clearly won’t have shared matches. However, they do match you and Kit A, both at 20 cM and over, so Kit B will see you as a shared match with Kit A, and Kit A as a shared match with you.

Kit C doesn’t match Kit B, so no shared matches with that person at all. Kit C does match you and Kit A. However, when Kit C clicks on shared matches for you, Kit A doesn’t show up because they only match Kit A on 9 cM. When Kit C clicks on Kit A for shared matches, you ARE listed as a shared match because you share 40 cM of DNA with Kit C.

There’s no way to discern whether two of your matches match each other unless they show as a match in the shared match tool. You can’t tell if their absence on the shared match list means they actually don’t match, or their shared match absence is because they match you at less than 20 cM.

Whew, that was a mouthful.

You may need to refer back to this from time to time if you’re confused by your shared matches at Ancestry.

If you need to remember rules, remember this.

  1. You can obtain shared matches with yourself plus any match, regardless of how much or how little DNA you share with that one match. Prove this to yourself by finding a match under 20 cM, like my 8 cM match, and viewing your shared matches.
  2. No one will show on a shared match list with another person unless they match you at 20 cM or greater. Prove this to yourself by viewing the smallest shared match with anyone.

Strategy

The takeaway of this is if you have a larger (20 cM or over) and smaller match (under 20 cM), always request shared matches from the perspective of the smaller match because the smaller match won’t show up as a shared match on any shared match list.

The only way you can see shared matches that includes people under 20 cM is to request to view shared matches with individual people who match you below 20 cM. 

In my case, I will never see KO on any shared match list because I only match KO at 8 cM. However, I can request my shared matches with KO in which case I’ll see all 20 cM or greater shared matches with KO.

Alternatives

Every vendor provides a shared match feature, and each functions differently.

In the chart below, I’ve provided basic shared match information for each vendor.

If you’re interested in uploading your DNA file from Ancestry or another vendor, I’ve provided upload/download step-by-step instructions for each vendor, here.

Top Ten RootsTech 2022 DNA Sessions + All DNA Session Links

The official dates of RootsTech 2022 were March 3-5, but the sessions and content in the vendor booths are still available. I’ve compiled a list of the sessions focused on DNA, with web links on the RootsTech YouTube channel

YouTube reports the number of views, so I was able to compile that information as of March 8, 2022.

I do want to explain a couple of things to add context to the numbers.

Most speakers recorded their sessions, but a few offered live sessions which were recorded, then posted later for participants to view. However, there have been glitches in that process. While the sessions were anticipated to be available an hour or so later, that didn’t quite happen, and a couple still aren’t posted. I’m sure the presenters are distressed by this, so be sure to watch those when they are up and running.

The Zoom rooms where participants gathered for the live sessions were restricted to 500 attendees. The YouTube number of views does not include the number of live viewers, so you’ll need to add an additional number, up to 500.

When you see a number before the session name, whether recorded or live, that means that the session is part of a series. RootsTech required speakers to divide longer sessions into a series of shorter sessions no longer than 15-20 minutes each. The goal was for viewers to be able to watch the sessions one after the other, as one class, or separately, and still make sense of the content. Let’s just say this was the most challenging thing I’ve ever done as a presenter.

For recorded series sessions, these are posted as 1, 2 and 3, as you can see below with Diahan Southard’s sessions. However, with my live session series, that didn’t happen. It looks like my sessions are a series, but when you watch them, parts 1, 2 and 3 are recorded and presented as one session. Personally, I’m fine with this, because I think the information makes a lot more sense this way. However, it makes comparisons difficult.

This was only the second year for RootsTech to be virtual and the conference is absolutely HUGE, so live and learn. Next year will be smoother and hopefully, at least partially in-person too.

When I “arrived” to present my live session, “Associating Autosomal DNA Segments With Ancestors,” my lovely moderator, Rhett, told me that they were going to livestream my session to the RootsTech page on Facebook as well because they realized that the 500 Zoom seat limit had been a problem the day before with some popular sessions. I have about 9000 views for that session and more than 7,400 of them are on the RootsTech Facebook page – and that was WITHOUT any advance notice or advertising. I know that the Zoom room was full in addition. I felt kind of strange about including my results in the top ten because I had that advantage, but I didn’t know quite how to otherwise count my session. As it turns out, all sessions with more than 1000 views made it into the top ten so mine would have been there one way or another. A big thank you to everyone who watched!

I hope that the RootsTech team notices that the most viewed session is the one that was NOT constrained by the 500-seat limited AND was live-streamed on Facebook. Seems like this might be a great way to increase session views for everyone next year. Hint, hint!!!

I also want to say a huge thank you to all of the presenters for producing outstanding content. The sessions were challenging to find, plus RootsTech is always hectic, even virtually. So, I know a LOT of people will want to view these informative sessions, now that you know where to look and have more time. Please remember to “like” the session on YouTube as a way of thanking your presenter.

With 140 DNA-focused sessions available, you can watch a new session, and put it to use, every other day for the next year! How fun is that! You can use this article as your own playlist.

Please feel free to share this article with your friends and genealogy groups so everyone can learn more about using DNA for genealogy.

Ok, let’s look at the top 10. Drum roll please…

DNA Shows Peter Johnson and Mary Polly Philips Are My Relatives, But Are They My Ancestors? – 52 Ancestors #350

One of the requests by several people for 2022 article topics revolved in some way around solving challenges and showing my work.

In this case, I’m going to show both my work and the work of a newly-discovered cousin, Greg Simkins.

Let’s start by reminding you of something I said last week in Darcus Johnson (c1750-c1835) Chain Carrier – Say What??.

Darcus is reported in many trees to be the daughter of Peter Johnson (Johnston, Johnstone) and his wife Mary Polly Phillips. Peter reportedly lived in Pennsylvania and died in Allegheny County, PA. However, I am FAR from convinced that this couple was Darcus’s parents.

The distance from Shenandoah County, VA to Allegheny Co., PA is prohibitive for courting.

The Shenandoah County records need to be thoroughly researched with various Johnson families reconstructed. I’m hoping that perhaps someone has already done that and a Johnson family was living not terribly far from Jacob Dobkins father, John Dobkins. That would be the place to start.

Greg, Peter Johnson’s descendant through son James reached out to me.

Hi Roberta, I read your essay today on Dorcas Johnson. I wanted to write to you because I am a descendant of Dorcas’s brother James and have DNA matches to support our connection.

Clearly, I was very interested, but I learned long ago not to get too excited.

Then, Greg kindly shared his tree and DNA results with me. He was also generous enough to allow me to incorporate his information into this article. So yes, this article is possible entirely thanks to Greg.

I was guardedly excited about Greg’s communication, but I wasn’t prepared for the HUGE shock about to follow!

Whoa!!!

Greg has done his homework and stayed after school.

First, he tracked the descendants of Peter through all of his children, to present, where possible, and added them into his trees at the genealogy vendors. The vendors can do much better work for you with as much ammunition as you can provide.

Second, he has doggedly tracked matches at MyHeritage, FamilyTreeDNA, Ancestry and GEDmatch that descend through Peter Johnson and Mary Polly Phillips’s children. By doggedly, I mean he has spent hundreds to thousands of hours by his estimation – and based on what I see, I would certainly agree. In doing so, he pushed his own line back from his great-great-grandmother, Elizabeth Johnson, three generations to Peter Johnson and Mary Polly Phillips – and proved its accuracy using DNA.

Altogether, Greg has identified almost 250 matches that descend from Peter Johnson and Mary Polly Phillips, and mapped those segments across his chromosomes.

Greg made notes for each match by entering the number of matching cMs into their profile names as a suffix in his tree. For example, “David Johnson 10cM” instead of “David Johnson Jr.” or Sr.  That way, it’s easy to quickly see who is a match and by how much. Brilliant! I’m adopting that strategy. It won’t affect what other people see, because no living people are shown in trees.

Of course, DNA is on top of traditional genealogical research that we are all familiar with that connects people via deeds, wills, and other records.

Additionally, Greg records research information for individuals as a word document or pdf file and attaches them as documents to the person’s profile in his tree. His tree is searchable and shareable, so this means those resources are available to other people too. We want other researchers to find us and our records for EXACTLY this reason.

One thing to note is that if you are using Ancestry and use the Notes function on profiles, the notes don’t show to people with whom you share your tree, but links, sources and attached documents do.

Greg has included both “Other Sources” and “Web Links” below.

For example, if I click on Greg’s link to Historic Pittsburg, I see the land grant location for Peter Johnson. Wow, this was unexpected.

Ok, I love maps and I’m hooked. Notice the names of the neighbors too. You’ll see Applegate again. Also, note that Thomas Applegate sold his patent to Richard Johnson. Remember the FAN club – friends and neighbors.

Ok, back to DNA for now.

The Children

Ancestors with large families are the best for finding present-day DNA matches. Of course, that’s because there are more candidates. More descendants and that means more people who might test someplace. This is also why you want to be sure to have your DNA in all 4 major DNA vendors, FamilyTreeDNA, MyHeritage, Ancestry, and 23andMe, plus GEDmatch.

This is a portion of Greg’s tree that includes the children of Peter Johnson and Mary Polly Phillips. Note that two Johnson females married Dobkins men. I’ve always suspected that Margaret Johnson and Dorcas Johnson were sisters, but unless we could use mitochondrial DNA, or figure out who the parents of either Peter or Mary are, there’s no good way to prove it.

We’re gathering some very valuable evidence.

At Ancestry, Greg has 85 matches on his ThruLines for Peter Johnson and Mary Polly Phillips, respectively.

  • Of course, Greg has the most matches for his own line through Peter’s son James Johnson (1752-1826) who married Elizabeth Lindsay and died in Lawrence County, IL: 35 matches.
  • Next is Margaret Johnson (1780-1833) who married Evan Dobkins in Dunmore County, VA, brother of my ancestor, Jacob Dobkins. She probably died in Cocke County, TN: 25 matches. Dorcas named one of her children Margaret and Margaret may have named one of her children Dorcas.
  • Solomon Johnson (1765-1843) married Frances Warne and stayed in Allegheny County, PA: 8 matches. Notice one of Peter’s neighbors was a Warner family. Dorcas named one of her children Solomon, a fairly unusual name.
  • Mary Johnson (1770-1833) married Garrett Wall Applegate and died in Harrison County, IN: 7 matches. The Applegates were Peter Johnson’s neighbors and Garrett served in the Revolutionary War in the 8th VA Regiment. Clearly, some of these settlers came from or spent time in Virginia.
  • Dorcas Johnson (c1750-c1835) married Jacob Dobkins in Dunmore County, VA and died in Claiborne County, TN: 5 matches.
  • Peter Johnson (1753-1840) married Eleanor “Nellie” Peter and died in Jefferson County, KY: 4 matches.
  • Richard D. Johnson (1752-1818) married Hannah Dungan and Elizabeth Nash: 2 matches.

Unfortunately, since most of those matches are between 7 and 20 cM, and Ancestry does not display shared matches under 20 cM, we can’t use Ancestry’s comparison tool to see if these people also match each other. That’s VERY unfortunate and extremely frustrating.

Greg matches more people from this line at MyHeritage, GEDmatch and FamilyTreeDNA, and thankfully, those vendors all three provide segment information AND shared match information.

Cousins Are Critical

While Greg, unfortunately, does not match me, he does match several of my cousins whose tests I manage.

Two of those cousins both descend from Darcus Johnson through her daughter Jenny Dobkins, through her daughter Elizabeth Campbell, through her daughter Rutha Dodson, through her sons John Y. Estes and Lazarus Estes, respectively.

Another descends through Jenny Dobkins son, William Newton Campbell for another 5 generations. These individuals all match on a 17 cM segment of Chromosome 20.

Other known cousins match Greg on different chromosomes.

Looking at their shared matches at FamilyTreeDNA, we find more Dobkins, Dodson and Campbell cousins, some that were previously unknown to me. One of those cousins also descends through William Newton Campbell’s daughter for another 4 generations and matches on the same segment of chromosome 20.

DNAPainter

Emails have been flying back and forth between me and Greg, each one with some piece of information that one of us has found that we want to be sure the other has too. Having research buddies is wonderful!

Then, Greg sent a screenshot of a portion of his chromosome 20 from DNAPainter that includes the DNA of the cousins mentioned above. I didn’t realize Greg was using DNAPainter. It’s an understatement to say I’m thrilled because DNAPainter does the cross-vendor triangulation work automatically for you.

Just look at all of those matches that carry this Johnson/Phillips segment of chromosome 20. Holy chimloda.

Greg also sent his DNAPainter sharing link, and it turns out that this is only a partial list, with one of my cousins highlighted, dead center in the list of Peter Johnson’s and Mary Polly Phillip’s descendants. Greg has even more not shown.

Trying Not to Jump to Conclusions

I’m trying so hard NOT to jump to conclusions, but this is just SOOOO EXCITING!

Little doubt remains that indeed, Peter Johnson and Mary Polly Phillips are the parents of Dorcas Johnson who married Jacob Dobkins and also of Margaret Johnson who married Evan Dobkins. I’ve eliminated the possibility of other common ancestors, as much as possible, and verified that the descent is through multiple children. This particular segment on chromosome 20 reaches across multiple children’s lines.

I say little doubt remains, because some doubt does remain. It’s possible that perhaps Dorcas and her sister weren’t actually daughters of Peter Johnson, but maybe children of his brother? Peter was reported to have a brother James, a sheriff in Cumberland County, PA. but again, we lack proof. If Dorcas is Peter Johnson’s niece, her descendants would still be expected to match some of the descendants of Peter and his wife.

Also complicating matters is the fact that Greg also has a Campbell brick wall with a James Campbell born about 1790 who lived in Fayette County, PA, in the far northwest corner of the state. Therefore, DNA matches through Dorcas Johnson Dobkins’s daughters Jenny and Elizabeth who married Campbell brothers need to be verified through her children’s lines that do NOT descend through her daughters who married Campbell men.

Nagging Questions

I know, I’m being a spoilsport, but I still have questions that need answers.

For example, I still need to account for how the Johnson girls managed to get to Shenandoah County, VA (Dunmore County at that time) to meet the Dobkins boys, spend enough time there to court, and then marry Evan and Jacob nine months apart in 1775. Surely they were living there. Young women simply did not travel, especially not great distances, and marriages occurred in the bride’s home county. Yet, they married in Shenandoah County, VA, not in PA.

What About the Records?

We are by no means done. In fact, I’ve just begun. I have some catching up to do. Greg has focused on Peter Johnson and Mary Polly Phillips in Pennsylvania. I need to focus on Virginia.

Of course, the next challenge is actual records.

What exists and what doesn’t? FamilySearch provides a list for Dunmore County, here, and Shenandoah, here.

Was Peter Johnson ever in Dunmore County that became Shenandoah County, VA, and if so when and where? If not, how the heck did his two daughters marry the Dobkins boys in 1775? Was there another Johnson man in Dunmore during that time? Was it James?

Where was Peter Johnson in 1775 when Dorcas and Margaret were marrying? Can we positively account for him in Pennsylvania or elsewhere?

Some information has been published about Peter Johnson, but those critical years are unaccounted for.

It appears that the Virginia Archives has a copy of the 1774-1776 rent rolls for Dunmore County, but they aren’t online. That’s the best place to start. Fingers crossed for one Peter Johnson living right beside John Dobkins, Jacob’s father. Now THAT would convince me.

Stay tuned!

Note – If you’d like to view Greg’s tree at Ancestry, its name is “MyHeritage Tree Simkins” and you can find it by searching for Maude Gertrude Wilson born in 1876 in Logan County, Illinois, died January 27, 1950 in Ramsey County, Minnesota, and married Harry A. Simkins. Elizabeth Ann Johnson (1830-1874) is Maude’s grandmother.

Ancestry Rearranged the Furniture

I’ve been reading about recent visual design changes occurring at the Ancestry website and that the changes were being rolled out gradually to groups of users. Yesterday, I experienced it firsthand.

Why is Ancestry making changes? Ancestry said they wanted a new look and feel and to improve standardization across the site and across all ancestry sites around the world.

Colors, fonts, icons, avatars, buttons, and their landing page have changed, but the underlying functionality, for the most part, has not. You can read more about Ancestry’s new look and feel, here.

What’s New?

A week or two ago, I received changes to my tree. I thought all of the changes were rolled out at once, but yesterday, I discovered that wasn’t the case.

When I signed in yesterday morning, I discovered an entirely new look and feel.

Here’s what greeted me.

This looks nothing like the previous night. I had to sit there for a minute to reorient myself. Wow.

Next, a tour popped up. I was glad to see that, but don’t click away because you can’t get the guided tour back again. It looks like there are only three little dots, so maybe I didn’t miss much.

I generally don’t mind the pain of change if there is something good or new to go along with it. For the most part, Ancestry’s changes are cosmetic, meaning they rearranged the furniture, although there are some cool new features, but nothing DNA-related. Let’s see what they did, section by section, and how it affects users.

Make Discoveries

Ancestry shows you what you were doing when you were last signed in and gives you the option to resume where you left off. That’s pretty cool, because if you’re like me, you probably don’t remember, and you might not be done. Are genealogists ever finished?

Ancestry has also customized your hints, discoveries, and photos based on what you were doing.

I quickly discovered that if something is showing that you want to see, click on it, because if you get distracted and do something else, that “hint” won’t be waiting when you return because Ancestry customizes what is offered to you based on what you did last. They display the last three people you worked on at the top, but sometimes the hints aren’t for those people.

If you have multiple trees, selecting a different tree under the “Make discoveries” dropdown box changes what is shown in the “Family photos” section to the selected tree.

The name on the front of the “Family Photos” item displays the name of the person it’s connected to in someone else’s tree.

Normal caveats here:

  • This may not be your ancestor.
  • It may be someone else by the same or a similar name.
  • The item may be incorrectly saved to someone who is supposed to be your ancestor.

If you click on an image, you’re taken to the familiar “Save” screen, with a few modifications.

I like this new feature generally, although I think it makes it more difficult to verify that the item is actually for your ancestor – which means it’s more likely that people will save the wrong thing to the wrong person. This means more errors in trees, especially for new genealogists or people new to the Ancestry interface.

What I’d like to see added is more information displayed from my tree for people Ancestry is suggesting I save an item to. As you can see, Ancestry does not display the birth and death dates of the person in my tree that they are suggesting I save this image to. I may have multiple people in my tree by that name, and often do.

You can see the birth and death dates in the tree of the person the item is currently saved to by mousing over the green bar at right, and you can see their profile by clicking on that green bar.

Clicking on “View all Photos” takes you to an “All Hints” page where you can filter the results any number of ways. I like this feature too.

Keep in mind that these documents aren’t just for your direct ancestors, but for anyone in your tree. I wish “direct ancestors” was a filter option, but it isn’t.

DNA

The next section shows my newest DNA matches, my Ethnicity estimate, and Traits.

Clicking on your matches or ethnicity takes you to the normal locations, respectively.

Don’t expect to have Traits unless you’ve purchased that upgrade, and no, I haven’t.

The good news is that having DNA displayed on the main dashboard page encourages people to check their results and work with their DNA matches. You can still access your results from the DNA tab at the top – like always.

The bad news is that there are no new DNA features☹.

Don’t neglect to check your DNA matches, ThruLines and Communities periodically to see if anything has changed or hints might have developed that could be useful to you.

Search

The Search box location now resides on the right side of the page or you can click on the search tab at the top of the dashboard.

I was unhappy to discover that the box for the US census years is now gone. I used it a lot.

The “Advanced search” link is still there, but that function has changed a bit too. Mostly, it’s just a matter of getting used to the rearranged furniture and experimenting a bit.

There is a US census link on the advanced page which in another click or two allows you to select specific census years.

Unfortunately, “Quick Links” are going away. You can’t save new ones. Ancestry says the existing ones are remaining, but I don’t know for how long.

Ancestry has been improving searches gradually over the past few weeks, which I do find helpful. Specifically, that already-saved items returned in searches for a specific ancestor are now grouped together as a result of having “Smart filtering” turned on.

What I would really like is for Ancestry to compare photos with items already in my gallery for each person and NOT show me the same photo if I’ve either saved or dismissed it for that individual.

I would love to be able to see if a particular document or image has already been saved to my ancestor’s profile when I’m seeing search results. Not only do I not want to save or dismiss it again, I don’t want to see it again, even if it has been saved to another user’s tree by a different name. If Apple Macs can do image recognition, so can Ancestry.

Why is this important? You can see my ancestor’s photo being offered again, above – 6 times to be exact if you scroll down. Here’s another example.

Yea, I don’t want all of those DNA match icons people save to their trees offered over and over again. Also, those immigrant ships, especially for ancestors who weren’t immigrants. Nor do I want 20 copies of the exact same picture of their tombstone. A picture by any other name is still a thorn!

One of the beneficial updates, especially for new researchers, is that Ancestry Academy is a link under tools and resources. You can check out Ancestry Academy videos here.

Trees

I’ve saved the new trees for last.

I must admit, I’m not fond of the changes, but mostly because they are irritating, although less so now that Ancestry removed their new green text. The actual functionality hasn’t changed.

However, I’ve devised a strategy to deal with the single most irritating change.

Ancestry introduced new avatars. Unfortunately, they look overbalanced to me, or more specifically, like young people that all have dowager’s hump. They look like they are weighted down, struggling to move forward. Now that I’ve seen these, I can’t unsee them and I can’t NOT think of that when I do see them. (You’re welcome.)

What I can do is to save any photo or image to each ancestor’s profile. That’s where those Discovery Photos will come in handy, right?

Ancestry also gave several ancestors angel wings. Hmmm….

Then I realized those weren’t angels at all, but the new ThruLines emblem that indicates that this ancestor has ThruLines. Silly me, I thought maybe something like Find-A-Grave😊.

Ancestry also redesigned the leaf hint to be more stylized, but the hint works just the same as always. That leaf has evolved a lot over time.

I might tongue-in-cheek suggest that Ancestry’s cosmetic development efforts might have been better spent investing in something like, say, a chromosome browser. But hey, that’s just me.

One “improvement” Ancestry rolled out and has already removed, thankfully, is light green text pretty much every place. Trust me, it was worse than light grey, given what we need is black or a dark color on a white background for the highest contrast. I’m glad that green is mostly gone. I realize that green is Ancestry’s corporate color, but it made working with the website difficult. Ancestry does listen to feedback sometimes, in this case, great wailing and gnashing of teeth.

Ancestry initially provided a feedback button in the lower right corner, but they’ve since removed that easy communications method. If you want to provide feedback, positive or negative, you can call Ancestry support or provide feedback by scrolling to the bottom of any Ancestry page and click on “Support Center.”
