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

What Is Endogamy and Why Does It Matter?

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

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

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

This Article

This article serves two purposes.

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

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

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

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

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

I’ve previously written about endogamy in the articles:

Let’s start with definitions.

Pedigree Collapse and Endogamy

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

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

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

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

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

Pedigree Collapse and Endogamy is NOT the Same

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

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

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

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

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

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

Endogamy Doesn’t Necessarily Indicate Recent Pedigree Collapse

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

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

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

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

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

Endogamous Groups

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

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

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

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

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

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

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

Endogamy is a process that occurs over time.

Endogamy and Unknown Relatives

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

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

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

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

The Challenge

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

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

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

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

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

One Size Does NOT Fit All

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

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

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

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

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

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

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

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

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

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

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

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

Ethnicity and Populations

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

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

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

This individual at FamilyTreeDNA is 100% Ashkenazi Jewish.

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

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

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

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

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

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

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

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

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

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

Ethnicity Sides

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

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

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

Here’s an example at 23andMe.

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

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

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

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

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

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

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

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

Let’s look at another example.

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

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

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

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

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

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

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

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

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

Ancestry’s DNA Communities

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

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

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

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

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

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

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

MyHeritage’s Genetic Groups

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

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

You can also sort your matches by Genetic Groups.

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

I wrote about Genetic Groups, here.

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

Matches

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

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

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

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

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

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

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

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

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

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

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

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

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

In fact, in order:

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

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

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

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

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

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

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

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

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

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

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

Matching Location at MyHeritage

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

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

AutoClusters

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

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

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

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

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

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

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

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

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

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

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

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

Endogamous Relationships

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

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

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

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

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

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

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

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

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

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

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

However, in these dozen examples:

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

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

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

Furthermore, it can get more complex.

Half Endogamous

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

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

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

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

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

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

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

However, that’s not universally what we see.

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

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

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

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

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

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

Ancestry and Timber

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

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

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

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

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

Endogamous Segments

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

How and why does this happen?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

More, Smaller Segments

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

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

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

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

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

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

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

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

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

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

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

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

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

Endogamy, Segments, and Distant Relationships

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

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

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

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

“Are Your Parents Related?” Tool

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

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

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

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

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

Click on “Are your parents related?”

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

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

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

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

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

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

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

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

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

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

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

Let’s look for more clues.

Surnames

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

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

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

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

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

You can evaluate in either or both of two ways:

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

Here are some examples from our testers.

Jewish – Closest surname matches.

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

Acadian – Closest surname matches.

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

Native American – Closest surname matches.

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

You may recognize these categories of surnames immediately.

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

The most unusual surnames are likely your best bets.

Projects

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

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

Scroll down until you see this image.

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

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

These results are for Muise, an Acadian surname.

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

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

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

Locations

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

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

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

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

Y DNA, Mitochondrial DNA, and Endogamy

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Discover for Y DNA Only

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

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

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

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

You’ll be treated to:

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

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

Endogamy Tools Summary Tables

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

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

Summary of Endogamy Tools by Vendor

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

 Tool 23andMe Ancestry FamilyTreeDNA MyHeritage GEDMatch
Ethnicity Yes Yes Yes Yes Use the vendors
Ethnicity Painting Yes + segments Yes, limited Yes + segments Yes

Summary of Endogamous Populations Identified by Each Tool

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

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

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

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

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

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

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

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

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

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.

STOP, THINK & RUN – Stop Innocently Giving Your Information to Cybercrooks on Social Media

Yes – you. All of us. This article is written for and applies to everyone.

We are all targets for social engineering which is the act of manipulating, influencing or deceiving people into performing actions or divulging confidential information – generally by engaging you or manipulating your emotions.

The most skilled cybercriminals accomplish their goal without you even being aware of what’s going on. You’re relaxed and just enjoying yourself, checking your social media news feed. No Nigerian princes needed anymore. They’ve moved on, taken on new personas, but are still targeting you.

Literally, everyone is a target.

The Bad Guys Kicked It Up a Notch

The bad guys have improved their skills. Attackers find loopholes and opportunities where you least expect them. They gain your trust or take advantage of your defenses being down – and they are very skilled at what they do.

I see people who I would think should know better engaging in risky behavior every single day, probably because they aren’t aware that the nature of the threats has evolved and changed. The bad guys stay one step ahead of us.

Please read this article even if you know what you’re doing. Someone you care about may not and you can help them.

Social Media

We all want to use social media and public platforms for genealogy and communicating with family and friends. We need to realize that because of the open nature of those platforms, they are full of bad actors trying to take advantage of us in seemingly innocent ways.

Not to mention that the platform is free for users, so access to you IS the commodity. Not just through ads, which you can clearly recognize as such, but by manipulating your behavior.

How, by luring you with “free,” “fun” or “missing out.”

Seriously, you do NOT need a new “free” improved profile picture.

Furthermore, some unnamed person or site you don’t know doesn’t really care about the TV show you watched when you got home from school as a kid.

Well, actually they DO care, but it’s not innocent. Scammers and bad actors gather, aggregate, and distill data about us hoping to breach our electronic security – and/or that of our social media friends.

Even if the person or account asking isn’t malicious, if the post is public, cybercriminals can and do gather and compile information about YOU that they find on public postings and pages.

Why?

In an attempt to defraud you, AND your friends who will also fall for these schemes. If your friends see you do something, they are more likely to engage in the behavior themselves. Just the act of answering these seemingly innocent questions conveys information about you.

  • First, you’re vulnerable and don’t understand that “public posts” and resulting answers make you a target. In other words, you’re advertising that you’re a good target.
  • Second, if you don’t have your Facebook (or other social media) account locked down so that only friends of friends can send you friend requests, it’s not unusual to receive a whole raft of friend requests after doing something public.
  • Third, even if your account is locked down tight, your comment or answer to that seemingly innocent public posting may net you a reply something like this:

Note the bad grammar and lack of punctuation. Probably that Nigerian prince again, with a bogus profile picture.

If people can see your “About” information, the message or reply may be more specifically tailored – targeting you with some common interest. Single middle-aged female? You’ll receive a message from a “widowed” male about that same age, maybe wearing a uniform or otherwise looking like a model, holding a puppy. Yea, right.

Now, holding the 1890 census – that might be an effective scheme to target genealogists😊

Let’s talk about how to stay safe and still be able to benefit from and enjoy social media.

We will begin with a big red flag.

NewProfilePic

The current rage is an artificial intelligence oil painting profile picture that’s “free.”

Right off the bat, you need to always be suspicious of anything “free” because it often means “they,” whoever they are, want your information and are willing to give you something to get it – under the guise of free. Speaking of them, just who are “they” anyway? That’s the first question you need to ask and answer before engaging.

Free almost always never benefits you.

Why would anyone want to give you a cool new profile picture for free? It may only take a few computer cycles, but it’s not free for them to produce, just the same, especially not when multiplied by the tens of thousands. What are they getting out of all those free photos they are producing?

I’ll tell you what. To gain access to your data – including the data on your phone.

Hmmm, I want you to think about something for a minute.

Do you have your phone set or apps set to scan your face and automatically open? Is that your security? For your bank account maybe too?

And you just sent a photo of your FACE to some unknown person or group in some unknown place?

Really?

You can change a lot of things, but you cannot change your face and facial recognition software is powerful.

Snopes says the NewProfilePic app really isn’t any worse than many other apps – which isn’t saying much.

Aside from the fact that NewProfilePic was initially registered in Moscow, which should be a HUGE red flag by itself, especially right now, what can the app do on your phone?

Here’s the list.

In essence, you just gave someone the keys to the candy store.

In perpetuity.

Is your blood running cold? It should be.

Still think this fun new app is “free?” You’re paying for it dearly, and may yet pay for it even more dearly.

Here’s a warning from a state Attorney General and here’s an article from MLive that interviewed a cybersecurity expert who notes that this app scrapes your Facebook data.

However, so do other people and apps.

Public is Public

When you see anything on Facebook with the little globe, that means that anyone anyplace can see this posting AND all replies, including your answers. Everything is fully public.

In this case, more than 80,000 people answered this question from an entirely unknown person or website.

Just a couple of days later, this same posting had 54K likes, more than half a million comments, and more than 6,100 shares. That’s how effective this type of seemingly innocent question can be.

Several of my friends answered.

What does this question tell anyone looking? Your approximate age, for beginners.

Maybe an answer to a security question. Just google “top security questions for gaining access to forgotten passwords.”

Engaging with a web page also means the Facebook algorithm will send you more postings from that website in your feed. So maybe if this post doesn’t yield anything useful about you, the next one might.

Cumulatively, many answers to many postings will reveal a lot.

Never answer these.

But There’s More

Because this posting is public, I can click on the name of ANY person who has answered that public question and see every other public thing they’ve shared on their timeline.

As an example, I randomly selected Charlotte, someone that I don’t know and am not friends with who replied to that question. (You can do this same experiment.)

I clicked on her name and scanned down Charlotte’s postings. I can immediately see that she’s a good target and has fallen for several other things like this.

Here’s one from her page.

That scammer, James, latched onto her immediately. Again. Note the grammar.

Here’s another seemingly innocent game that Charlotte played to get a new Facebook profile picture and “secret” info about herself. That “4 Truths” app told Charlotte that she was very mysterious and promised to “show what’s hidden in you.” Of course, she had to provide her photo, give permission for this app to post on her timeline, publicly, and access her Facebook account. Charlotte probably didn’t even realize that was happening, or what it meant was happening behind the scenes to her data.

But now Charlotte has the new NewProfilePic oil portrait, so this one isn’t in use anymore. Maybe Charlotte’s friends wanted some nice things said about them too so they might have clicked on this same link. Just for fun, right? That’s how these scams work.

These unfortunate choices on Charlotte’s timeline were accompanied by many more that were similar in nature. Those were interspersed with notices on her Facebook page that she has been hacked and not to accept any new friend requests or messages from her. The effects are evident.

It’s worth noting that some people do have their profiles cloned and haven’t engaged in any risky behavior like this, However, you dramatically increase your odds of being compromised when you engage in risky online behaviors. Every time someone clones your profile and sends messages to all of your friends with malware links, it increases the cyberthief’s harvest of you and your friends. Cha-ching!

Eventually, the bad actors will find people who they can scam, either by:

  • Talking your friend, their target, into doing something bad for them, maybe thinking they are helping you or responding to you
  • By sending malware links that people click on thinking the message with the link is actually from you.
  • Gathering enough information to breach you or your friends’ security questions and clean out bank accounts.

No, I’m not fearmongering or being overly dramatic.

I utilize KnowBe4, a security and vulnerability consulting and training company to keep abreast of threats. You can follow their blog articles, here.

How Do Cybercrooks Access Your Friends?

Looking at Charlotte’s Facebook page, all of her friends are exposed too because they are publicly visible. Everyone can view the entire list of Charlotte’s friends.

Now, all of those scammers have access to Charlotte’s friends. Hence, the scammers can clone Charlotte’s account by stealing her photo, setting up a new account, and sending messages to Charlotte’s friends who think the message is from Charlotte. Something like “Try this new photo app, I did,” or, “Can you pick up an Apple gift card and send it to my friend for me?” You get the drift.

If Charlotte’s friends have their security set to only accept friend requests from someone that also shares a friend, and Charlotte accepts a bogus friend request – then the scammer can send her friends a friend request too and they think it’s Charlotte’s friend.

In other words, seeing a common friend causes Charlotte’s friends to let their guard down. I look at it this way – only one of my friends has to accept a bogus friend request to make me vulnerable too.

Charlotte also told people in a public posting that she was visiting someone on a specific day in another city. How do I know it’s another city? Because Charlotte has posted where she is from, where she lives, works, and the high school she attended in her “About” information.

Hmmm, those are security questions too.

That same website where I found Charlotte answering that question has also posted questions about your pet names.

What is one of the security questions if you lose your password?

Yep, pet names.

Nope, those seemingly cute sites aren’t. They are data-mining and gathering information.

Predatory Sites

First, I need to say that there are three security threats involved with these postings and websites:

  1. Any link you click which may take you to who-knows-where.
  2. That the site itself is data mining. However, this is not always the case. Some very legitimate companies ask questions to get you to engage in their subject topic. However, if the post is public, that’s an open door to the next threat.
  3. “People” or bots who harvest information about people who answer those public posts and then data-mine their accounts.

Let’s look at a few examples.

No person you don’t know cares at all about what you drank last. However, that might be valuable data for other reasons.

Facebook makes these things even more attractive to you by showing you answers from people on your friends list. I’m not going to embarrass my friends and family by showing their identity, even though it is completely public, but please, FOR THE LOVE OF ALL THAT’S HOLY, stop doing this.

Just look at that – 14 million comments and 193 thousand shares. For a data miner, this has been extremely successful.

To make matters worse, if you engage with a site on Facebook, they show you more from that site in your feed in the future. Since I clicked on these to write this article, my feed is going to be flooded with smarmy questions from these sites for days or weeks.

Let’s take a look at a few more examples.

Look at this one. 200,000 people and almost 3000 shares in two months. That means that this question appears on 3000 people’s timelines. It’s like a huge data-gathering pyramid scheme.

You’re likely to be wearing your favorite color and eat your favorite food.

How could this be used against you?

Yep, security, password, or account recovery questions again.

When I went to the page that made this posting, the next posting was a question – “In 1980, you were…” and the first person to answer said, “2 years old.” That person just told the world they were born in 1978.

Did you really want to do that?

Private Groups

You are safer in a private group, meaning only group members can see your posts.

You can tell if a Facebook group is private based on the lock and the words, “Private Group.” You can also see a list of your friends who are members of that group as well. Remember that the criterion for joining a private group differs widely and there are still lots of people you don’t know. Some private groups that I’m a member of have more than a quarter-million subscribers.

Most private groups are focused on a specific topic. Some private groups require answering application questions to join, and others don’t.

You’re safest in a group that does require questions to be answered which allows administrators who are familiar with the topic to craft questions that (hopefully) weed out most of the trolls, bots, and shady characters. That’s the choice I’ve made for the groups I co-administer, but it does require more attention from the administrators, which is why large groups often don’t implement membership questions.

Determining Privacy Settings

When you’re looking at the privacy settings on groups, posts on your friends’ timelines, or your own, you can mouse over the privacy icon. Facebook will tell you exactly who can see this post.

You’re never entirely safe. In addition to behaving safely as noted above, there are steps you can take to educate yourself and configure your social media accounts securely.

How to Stay Safe

Every social media platform is different, but I’m using Facebook as an example. Every platform will have a similar privacy function. Learn how it works.

Go to the Facebook help center, here and do a security checkup, here.

However, neither of those really address privacy, which I feel is actually the biggest security threat – the trapdoor or slippery slope.

Here’s how to access and review your privacy settings.

Click on the down arrow beside your name.

Click on Settings and Privacy, then both the Privacy Checkup and the Privacy Center.

Next, you’ll see several short articles. Be sure to step through each one

Take a few minutes to lock your account down.

The ONLY thing that is automatically public is your profile photo and any photo you use for your cover photo. Anything else can and should be restricted.

Facebook owns Instagram so you can set your Instagram security here too.

You’re not quite finished yet!

Monitoring and Controlling Apps

Next, we’re going to see what apps are installed and interacting with Facebook. Have you authorized apps you weren’t aware of?

In the dropdown arrow to the right of your name in the upper right-hand corner, click on the down arrow again.

You’ll see the Settings gear under “Settings and Privacy.” Click there to see all of the setting categories in the panel on the left side of your screen.

Review everything, of course, but pay special attention to “Apps and Websites” and “Games.”

Predatory operators will fool you into doing something fun, like a profile photo app, or a little game that provides you with your Fantasy Name or something else cute and enticing. That “free” game or app installs software. If you find software during your review, especially from something like we’ve been discussing, I recommend deleting it immediately.

Be sure you only have things you’ve intentionally installed or authorized.

THINK – Stop, Think and Run

When you see “someone” asking a question on Facebook, STOP!

You’ve heard of stop, drop and roll if your clothes are on fire?

Someone trying to breach your privacy is a digital fire, so this is stop, think and run.

Think about who is actually asking and why. “Who” is asking is NOT that cousin who shared the question from that public site. The “who” that is asking is that original site.  They are simply taking advantage of and using your cousin. I hate to put it this way, but always assume the worst and remember that even if the site itself is innocent, all of the people who can harvest your data and try to compromise your security assuredly are not.

Those “fun” sites asking those questions are either actively recruiting you or best case, leaving the door wide open for cyberthieves.

Don’t answer. No matter how much you’re tempted to share some nostalgic information or the name of your deceased pet you’re still grieving. No matter if you notice that your cousin or friend has replied already. Just don’t.

Stop, think, run. It’s that simple.

And speaking of your cousins or friends – if they have shared something that could compromise their security and privacy, not to mention their friends (including you), feel free to share this article or others, such as KrebsonSecurity. Take a look at Krebs’ examples of baiting you with childhood and puppy photos with corresponding questions. Do they evoke an emotional response from you? They are meant to. I mean, how bad can it actually be to enter the name of your beloved childhood pet?

By now, you should be screaming the answer to “how bad”!

Here’s an article from Tulane University. Yes, they are advertising their degree in cybersecurity management, but they do so by summarizing the things that social media users need to be concerned about.

I also follow a company called Facecrooks which monitors and writes about Facebook privacy, fraudsters, other scams, and such. They have a Facebook page here and a Scam Watch page here.

The Baker’s Dozen Messages

The messages I want to leave you with, aside from stop, think and run, are this:

  1. Nothing is free
  2. Think before you engage or answer
  3. Remind yourself that a stranger really doesn’t care about your first-grade teacher’s name, but a crook does
  4. Just because someone you know answered or engaged doesn’t mean it’s safe
  5. Consider potential consequences
  6. Can something you are about to share be used to compromise either you, your family, friends’, or employer’s privacy or safety?
  7. Don’t overshare – only say what’s necessary
  8. Notice what is public and what is not – look for that globe and behave accordingly
  9. Don’t download or play free games, or send anything to a “free” website
  10. Don’t click on links to unknown places
  11. Don’t accept friend requests from people you really don’t know.
  12. Learn the warning signs of a fake profile and report them by clicking on the three dots to the right of the profile
  13. Don’t click on links in private messages and beware of suddenly receiving an “odd” message from someone you haven’t heard from in a while

I’ve written other articles about online privacy, security, and safety too.

Remember…

Stop. Think. Run.

Happy Census April Fool’s Day – aka – Where the Heck Are My Parents???

What did we expect anyway – combining those two events? That’s just an invitation to fate to mess with our heads.

Nevertheless, like the drunken fly willfully walking into the spider web like an addict, at 12:01 AM, I suddenly “remembered” that the 1950 census was released and just had to go and try it out instead of going to bed. Well, I told myself it was “before” going to bed but it was actually instead. Let’s just say I saw the sunrise from the far side instead of the near side and woke up a few hours later with my phone on my chest and my last piece of chocolate melted to me. We should have had a party. I think I have a genealogy hangover.

Yes, we addicts did put quite a load on the National Archives (NARA) system causing errors, but it didn’t go down entirely. Somebody in NARA-land heaved a huge sigh of relief. Never underestimate the tenacity or craziness of genealogists who were OF COURSE willing to stay up all night.

I wondered if NARA would actually be able to pull off the massive AI census index project – but they did. Hats off to their team! What an incredible gift – even if it is April Fool’s Day and my well-hidden ancestors are still laughing at my expense.

You can access the NARA census, here, and I provided a prep article here that shows you how to find enumeration districts which you will probably need.

Found

I found the family members that I knew the location where they were living AND they weren’t living in large cities.

For example, my maternal grandparents were living at 107 East Main in Silver Lake, Indiana. That’s a very small town, so even though the AI didn’t record my grandparents, or brother who was living with them, I just paged through those records because I knew they were living in Silver Lake, and there was only one enumeration district. Easy peasy.

What was interesting to me was that my grandfather, who was the Lake Township Trustee had worked 72 hours the previous week, and my grandmother had worked 25 as a secretary.

The confusing part is that he was the trustee, and I don’t think she worked for the township. The enumerator mixed them up, apparently. So, was it her that worked 72 hours?

But, where was my mother? Back to that in a minute.

On the other side of my family, my paternal grandfather was living in Harlan County, Kentucky in a relatively remote location, up on Black Mountain. I half expected him NOT to be enumerated at all because he was a bootlegger, but lo and behold, there he is listed as a ”farmer.” Well, I guess that’s sort of farming.

The interesting thing about this record is that they have a boarder living with them, 22-year-old James Holcomb.

Their daughter, Evelyn had a child two years later, in 1952, reportedly with one Jake or Jack Halcomb, but that situation was always pretty hush-hush. I suspect that Jake Halcomb was actually James Holcomb, which makes a lot of sense. Her older sister was married to a William Halcomb, so I wonder if these men were brothers. Another mystery to solve.

Missing

My paternal grandmother, Ollie Bolton Robbins is missing. She lived in Chicago which had hundreds if not thousands of census enumeration districts. I checked the address given when she died in 1955, and where my father was reportedly living at that time, all to no avail. They were not living there in 1950.

My father is also missing. He had married Ellen Copack in 1949 in Chicago but I’ve been unable to obtain the actual marriage application from the Cook County Clerk’s office which would have (hopefully) contained the addresses of the bride and groom. By 1952, they were living in Fort Wayne, Indiana.

I checked both locations using the census name search but there were just too many entries to peruse them all. I need to be able to hunt at the vendors for William with a spouse of Ellen plus age information.

He was like a leaf in a windstorm, blowing from place to place, so who knows where he was in 1950.

My mother is also missing, and that’s a whole other story for another article. A chapter of her life I didn’t know much about is slowly unfolding, and not very easily either.

Let’s just say I expected to find her living with her parents and my half-brother, but she’s not there. I used a surname search in Chicago, Illinois where she had previously lived, in Fort Wayne, Indiana where she later lived, and in Florida where she was for about a year in 1949 through early 1950. At least, I think she was there in early 1950. Regardless, I can’t find her either with just a name search so I’ll have to wait until I can combine that search with age and other defining factors.

Patience is not my strong suit! I’m signing up for the new MyHeritage Census Helper to let them do the heavy lifting for me when their indexing is ready.

MyHeritage Census Helper

MyHeritage is offering their new Census Helper tool for free, just in time for the 1950 census. You can read about it, here.

All you have to do is upload your tree and MyHeritage prepares a list of people based on your tree information who are likely to be found in the 1950 census.

By clicking on the orange “Research” button, MyHeritage finds other records that are available now and will help to focus the 1950 census search.

I need to add some additional records for both my mother and father so that MyHeritage “knows” where to potentially look for them in 1950 when their indexed census records become available.

Of course, you can order a DNA test while you’re there, or upload your DNA file from another vendor, here, which is also free.

Juicy Finds!

It has been fun to watch social media today as people search for and find their relatives in the 1950 census.

One person discovered that their mother had a child they never knew existed. Of course, that begs the question of what happened to that child, and why the researcher had never heard of them. So many possibilities.

Another person discovered quite valuable information that required me to draw a chart to understand. It answered a WHOLE LOT of questions about situations only whispered about in that family.

A third person discovered that their father was divorced, and he had not yet married their mother. Of course, now that requires more research.

So many people receive unexpected close DNA relatives and the 1950 census information may well provide hints and clues that might at least provide breadcrumbs to those answers. In some cases, the answers are right there, in black and white. I keep expecting a half-sibling match, or their children or even grandchildren perhaps, but so far…I’m still waiting.

Are you in every database? You don’t want to miss any matches and you never know where that much-needed match might test. You can upload your DNA file to both MyHeritage and FamilyTreeDNA in addition to GEDmatch. I wrote free step-by-step upload/download instructions for all the vendors, here.

The discovery that really touched my heart, though, was the person who discovered that their father WAS the census enumerator. His handwriting reached out to say hello some 72 years later.

What a perfect April Fool’s Day.

What have you discovered?

1950 Census Will Be Released on April Fool’s Day

The US 1950 census images will indeed be released by the National Archives on April Fool’s Day, 72 years after that census began. Talk about irony. I just have this feeling I’ll not be able to find everyone and they will all be laughing at me!

Were you planning on searching to find your ancestor or their descendants that day using the traditional vendors? April Fool! Not so fast.

The census is always released without an index. April 1st is the shot at the starting gate for the various vendors to index the records to add to their product offerings for their customers.

If you’d like to see what kinds of questions were asked in that census, and the instructions provided to enumerators, you can view the 1950 census instructions, here.

Peeking

However, you might, just might, be able to gain a peek into those records on April 1st, assuming you know where your relatives lived at that time, and maybe even if you don’t. There are multiple opportunities and methodologies, so let’s take a look at a few.

Steve Morse’s Census Enumeration District Finder

Steve Morse has created lots of tools for genealogists, but right now, his census enumeration district finder may save your bacon!

https://stevemorse.org/census/unified.html

Steve’s no-nonsense site provides two levels of detail. The first is at the city level, and then, if you know the house number and street, you can narrow the district further.

For example, my grandmother lived in Chicago at the time, so I entered that information.

I’m only showing a few of the districts in Chicago. There are literally hundreds, if not thousands. The House number and Street fields open up at this point.

I think I know the address where she might have lived, or did when she died 5 years later, so I entered 639 N. Kedzie.

Unfortunately, there are still too many districts, so I went to Google maps to find a cross street.

Fortunately, 639 Kedzie still exists, and the surrounding streets are shown, above. I entered Huron since that is the closest. Then I added Ohio.

I was able to narrow the district to two using Ohio and Huron. Adding Sawyer shows one of those districts, and adding Troy shows the other, so I’m wagering that Kedzie might have been the dividing line.

As a bonus, I located the building where she resided, at least at one point, Did my grandmother live in this building that’s now a church in 1950? We will see in just a couple days now.

MyHeritage

MyHeritage is providing 1950 census information on their 1950 Content Hub

https://www.myheritage.com/census/us/1950census/

If you create your tree on MyHeritage, the 1950 census hints will be provided to you for people in your tree as soon as they are indexed, and you can extract the data directly into that person’s profile.

Ancestry

Ancestry is providing a Census District Finder, but not at the address level. For Chicago, Ancestry is hopeless, at least until the indexing is completed, but for a small town, township or rural area, Ancestry’s maps work pretty well and are interesting.

https://www.ancestry.com/discoveryui-content/district-map/62308

My maternal grandparents lived in the small town of Silver Lake, Indiana

I entered the location. Ancestry displayed the original census map with a pin in that location. By clicking on that pin, Ancestry displayed the district number, above. I will look in district 43-13 to view the residents of Silver Lake on April 1st.

Be sure to take note of other information on the map. At right, there are special enumeration areas and schedules. Specifically, a Seminary and Hotel, and there’s no detailed map for Winona Lake.

Indexed Records

Finding the enumeration district and manually scrolling through the records may allow you to locate your relatives. Of course, if you don’t know where your ancestors were living in 1950, then you’ll need to wait for the indexed records.

As it turns out, your wait may not be that long.

The National Archives says that the census information will be available through a link, here, beginning April 1, and it will be released with a name index created using Amazon web services artificial intelligence.

Woohoo. This will certainly be a first if they can actually pull this off.

Indexed census records using artificial intelligence, meaning OCR, will be released as soon as possible by both Ancestry and MyHeritage.

Of course, validation of OCR records will need to be performed manually for a variety of reasons including poor handwriting, damage to the documents, or other issues. In other words, if you can’t find your family members, look for similar names or search creatively after the indexed census is released.

How much later in April will the vendors release their products? We don’t know. It’s a race to rival any Olympics and we’ll just have to wait and see.

You Can Participate

FamilySearch is launching a massive volunteer indexing effort, here. You can join with other genealogists. FamilySearch provides their records for free, of course, and you can append them to your ancestor on FamilySearch’s big tree.

Why is the 1950 Census Important?

People we know or knew were living in 1950. The census will, hopefully, help us locate our family members and flesh out their lives. For example, I’m not at all sure where my parents were living in 1950.

Anyone born before April 1950 will be recorded in this census. If you’re hunting for descendants of your grandparents, or great-grandparents, knowing where their children were living and who was in the family will provide valuable information as to where to look for other relevant records such as yearbooks, city directories, obituaries, wills and so forth.

If you’d like to DNA test some of those relatives and their descendants, you have to first locate them.

It seems like 70 years isn’t all that long ago, genealogically speaking, so I wasn’t initially terribly excited until I realized I didn’t know where my parents were living and wasn’t sure where my paternal grandparents were living. Furthermore, I want to know what kind of information will be revealed about other family members.

Who Are You Searching For?

Have you made a list of your relatives that would be beneficial to locate in the census?

I’ve created a list, with location and the enumeration district as closely as can be identified for now.

If you’re planning to do this before April 1, I wouldn’t wait much longer. Every genealogist in the country will be accessing those sites on April 1st, and the April Fool’s laugh just might be on all of us if we crash the entire system.

Happy hunting!

East Coast Genetic Genealogy Conference – Registration is Open!

Did you know that the East Coast Genetic Genealogy Conference (ECGGC, affectionally known as “eggs”) is taking place on April 23 and 24? If you haven’t heard of this conference before, that’s because this is its inaugural year.

ECCGC was initially scheduled to be held in Maryland, in person, but the uptick in Covid over the winter forced a go, no-go decision at a time when a virtual live-streamed conference assured everyone’s safety.

I’m excited about speaking, especially my opening keynote, “DNA – Past, Present and Future.” I’ll reflect a little, talk about the current state-of-affairs and then discuss what the future may hold. Just think what we will be able to do in the next decade, or two, based on how far we’ve come in the past 22 years.

Of course, the very best aspect of this two-day conference is that it’s entirely focused on genetic genealogy which makes it the PERFECT venue for Mitochondrial DNA Academy. More about that in a minute.

Speakers

The 23 speakers read like a who’s who in the genetic genealogy space. You can read about each speaker, here.

Schedule and Sessions

If you look at the sessions and schedule, here, you’ll notice that there are 37 sessions offered over two days. Simple math tells you that you can’t possibly attend all of those in two days – even if you stayed up all night.

The great news is that for all attendees, the sessions will be recorded and available to watch after the actual conference itself is over.

Mitochondrial DNA Academy – You’re Invited

I want to personally invite you to attend Mitochondrial DNA Academy, presented by Dr. Miguel Vilar, Dr. Paul Maier, and me.

Mitochondrial DNA is an incredibly misunderstood tool for genealogy. It seems that anytime someone mentions mitochondrial DNA on social media and asks if they should purchase a test, a cacophony of “buy an autosomal test instead” resounds, without even asking the purpose of the test in question, or what the person hopes to learn.

Understanding mitochondrial DNA itself, how it’s used, what to expect, and how to utilize the results for genealogy is key to making an informed decision.

For those of us who do work extensively with mitochondrial DNA, there’s still much to learn. Attending both Paul Maier and Miguel Vilar’s portions of the Academy is guaranteed to provide even experienced genetic genealogists with fascinating, detailed information. There’s something for everyone and a unique learning opportunity.

If you want to understand the science behind mitochondrial DNA, how it works, different types of mutations, extra and missing mutations, frequency, haplogroup formation, migration, populations, phylogenetic trees as well as how to tie all of this up in a bundle to use successfully for genetic genealogy – Mitochondrial DNA Academy is for you.

You may have noticed that the three of us constitute three-quarters of the Million Mito Project team, so you just might get an update on that project as well!

Register for the Conference

You can register, here, for $150 which provides access to both conference days and all of the recorded sessions after.

Sponsors

I want to say a big thank you to the ECGGC sponsors, DNAGedcom, Borland Genetics, MyHeritage, FamilyTreeDNA and mitoYDNA.org whose generous sponsorships offset the cost of the conference for attendees.

See you at the conference!

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…

FamilyTreeDNA Keynote, RootsTech Wrap + Special Show Pricing Still Available

Am I ever whipped. My two live Sessions that were actually a series of three classes each took place on Friday. Yes, that means I presented 6 sessions on Friday, complete with a couple of Zoom gremlins, of course. It’s the nature of the time we live in.

RootsTech tried something new that they’ve never done before. The Zoom class sessions were restricted to 500 attendees each. RootsTech was concerned about disappointed attendees when the room was full and they couldn’t get in, so we live-streamed three of my sessions to Facebook in addition to the 500 Zoom seats.

As of this evening, 6,800 of you have viewed the Facebook video, “Associating Autosomal DNA Segments With Ancestors.” I’m stunned, and touched. Thank you, thank you. Here’s the Facebook link, and here’s the RootsTech YouTube link.

My afternoon sessions, “What Can I DO With Ancestral DNA Segments?” can be viewed here at RootsTech or here on YouTube.

I must admit, I’m really, REALLY looking forward to being together again because RootsTech without the socializing and in-person Expo Hall just isn’t the same. Still, be sure to take a virtual walk through the Expo Hall, here. There’s lots of content in the vendors” booths and it will remain available for all of 2022, until the beginning of RootsTech 2023..

Between prep for my classes and presenting, I didn’t have a lot of time to watch other sessions, but I was able to catch the FamilyTreeDNA keynote and their 2022 Product Sneak Peek. Both were quite worthwhile.

However, I just realized that FamilyTreeDNA’s special show pricing promo codes are still valid for the next two days.

 Special Prices Are Still Available

Every single test that FamilyTreeDNA offers, including UPGRADES, is on sale right now by using special RootsTech promo codes. These prices are good for two more days, through March 7th, so if you want to purchase a Y DNA test, mitochondrial, or Family Finder autosomal test, or upgrade, click here to see the prices only available at RootsTech (and to you through my blog.) It’s not too late, but it will be soon.

FamilyTreeDNA’s Keynote

FamilyTreeDNA’s keynote was titled FamilyTreeDNA: 22 Years of Breaking Down Brick Walls.

I really enjoyed this session, in part because I’ve been a part of the genetic genealogy revolution and evolution from the beginning. Not only that, but I know every single person they interviewed for this video, and have for years. If you’ve been participating in genetic genealogy for some time, you’ll know many of these people too. For a minute, it was almost as good as visiting in person.

I’m going to share a few highlights from the session, but I’m also going to include information NOT in the video. I was one of the early project administrators, so I’ve been along for the ride for just a few months shy of 22 years.

FamilyTreeDNA was the first US company to enter the DNA testing space, the first to offer Y DNA testing, and the only one of the early companies that remains viable today. FamilyTreeDNA was the result of Bennett Greenspan’s dream – but initially, he was only dreaming small. Just like any other genealogist – he was dreaming about breaking down a brick wall which he explains in the video.

I’m so VERY grateful that Bennett had that dream, and persisted, because it means that now millions of us can do the same – and will into the future.

Bennett tells this better than anyone else, along with his partner, Max Blankfeld.

“Some people were fascinated,” Bennett said.

Yep, that’s for sure! I certainly was.

“Among the first genetic genealogists in the world.”

“Frontier of the genetic genealogy revolution.”

Indeed, we were and still are. Today’s genetic genealogy industry wouldn’t even exist were it not for FamilyTreeDNA and their early testers.

I love Max Blankfeld’s story of their first office, and you will too.

This IS the quintessential story of entrepreneurship.

In 2004, when FamilyTreeDNA was only four years old, they hosted the very first annual international project administrator’s conference. At that time, it was believed that the only people that would be interested in learning at that level and would attend a DNA conference would be project administrators who were managing surname and regional projects. How times have changed! This week at RootsTech, we probably had more people viewing DNA sessions than people that had tested altogether in 2004. I purchased kit number 30,087 on December 28, 2004, and kit 50,000 a year later on New Year’s Eve right at midnight!

In April 2005, Nat Geo partnered with FamilyTreeDNA and founded the Genographic Project which was scheduled to last for 5 years. They were hoping to attract 100,000 people who would be willing to test their DNA to discover their roots – and along with that – our human roots. The Genographic Project would run for an incredible 15 years.

In 2005 when the second Project Administrator’s conference was held at the National Geographic Society headquarters in Washington DC, I don’t think any of us realized the historic nature of the moment we were participating in.

I remember walking from my hotel, ironically named “Helix,” to that iconic building. I had spent my childhood reading those yellow magazines at school and dreaming of far-away places. As an adult, I had been a life-long subscriber. Never, in my wildest dreams did I imagine ever visiting Nat Geo and walking the marble Explorer’s Hall with the portraits of the founders and early explorers hanging above and keeping a watchful eye on us. We would not disappoint them.

That 100,000 participation goal was quickly reached, within weeks, and surpassed, leading us all to walk the road towards the building that housed the Explorer’s Hall, Explorers’ in Residence, and so much more.

We were all explorers, pioneers, adventurers seeking to use the DNA from our ancestors in the past to identify who they were. Using futuristic technology tools like a mirror to look backward into the dim recesses of the past.

The archaeology being unearthed and studied was no longer at the ends of the earth but within our own bodies. The final frontier. Reaching out to explore meant reaching inward, and backward in time, using the most progressive technology of the day.

Most of the administrators in attendance, all volunteers, were on a first-name basis with each other and also with Max, Bennett, and the scientists.

Here, Bennett with a member of the science team from the University of Arizona describes future research goals. Every year FamilyTreeDNA has improved its products in numerous ways.

Today, that small startup business has its own ground-breaking state-of-the-art lab. More than 10,000 DNA projects are still administered by passionate volunteer administrators who focus on what they seek – such as the history of their surname or a specific haplogroup. Their world-class lab allows FamilyTreeDNA to focus on research and science in addition to DNA processing. The lab allows constant improvement so their three types of genetic genealogy products, Y, mitochondrial and autosomal DNA.

Those three types of tests combine to provide genealogical insights and solutions. The more the science improves, the more solutions can and will be found.

If you watch the video, you’ll see 6 people who have solved particularly difficult and thorny problems. We are all long-time project administrators, all participate on a daily basis in this field and community – and all have an undying love for both genealogy and genetic genealogy.

You’ll recognize most of these people, including yours truly.

  • I talk about my mother’s heritage, unveiled through mitochondrial DNA.
  • Rob Warthen speaks about receiving a random phone call from another genealogist as his introduction to genetic genealogy. Later, he purchased a DNA test for his girlfriend, an adoptee, for Christmas and sweetened the deal by offering to “go where you’re from” for vacation. He didn’t realize why she was moved to tears – that test revealed the first piece of information she had ever known about her history. DNA changed her and Rob’s life. He eventually identified her birth parents – and went on to found both DNAAdoption.org and DNAGedcom.
  • Richard Hill was adopted and began his search in his 30s, but it would be DNA that ended his search. His moving story is told in his book, Finding Family: My Search for Roots and the Secrets in My DNA.
  • Mags Gaulden, professional genealogist and founder of Grandma’s Genes and MitoYDNA.org tells about her 91-year-old adopted client who had given up all hope of discovering her roots. Back in the 1950s, there was literally nothing in her client’s adoption file. She was reconciled to the fact that “I would never know who I was.” Mags simply could not accept that and 2 years later, Mags found her parents’ names.

  • Lara Diamond’s family was decimated during the holocaust. Lara’s family thought everyone in her grandfather’s family had been killed, but in 2013, autosomal DNA testing let her to her grandfather’s aunt who was not killed in the holocaust as everyone thought. The aunt and first cousin were living in Detroit. Lara went from almost no family to a family reunion, shown above. She says she finally met “people who look like me.”
  • Katherine Borges founded ISOGG.org, the International Society of Genetic Genealogy in 2005, following the first genetic genealogy conference in late 2004 where she realized that the genealogy community desperately needed education – beginning with DNA terms. I remember her jokingly standing in the hallway saying that she understood three words, “a, and and the.” While that’s cute today, it was real at that time because DNA was a foreign language, technology, and concept to genealogy. In fact, for years we were banned from discussing the topic on RootsWeb. The consummate genetic genealogist, Katherine carries DNA kits in her purse, even to Scotland!

Bennett says that he’s excited about the future, for the next generation of molecular scientific achievements. It was Bennett that greenlit the Million Mito project. Bennett’s challenge as a genetic genealogy/business owner was to advance the science that led to products while making enough money to be able to continue advancing the science. It was a fine line, but Max and Bennett navigated those waters quite well.

Apparently, Max, Bennett, and the FamilyTreeDNA customers weren’t the only people who believe that.

In January 2021, myDNA acquired and merged with FamilyTreeDNA. Max and Bennett remain involved as board members.

Dr.Lior Rauchberger, CEO of myDNA which includes FamilyTreeDNA

Dr. Lior Rauchberger, the CEO of the merged enterprise believes in the power of genetics, including genetic genealogy, and is continuing to make investments in FamilyTreeDNA products – including new features. There have already been improvements in 2021 and in the presentation by Katy Rowe, the Product Manager for the FamilyTreeDNA products, she explains what is coming this year.

I hope you enjoyed this retrospective on the past 22 years and are looking forward to crossing new frontiers, and breaking down those brick walls, in the coming decades.

Sneak Peek at FamilyTreeDNA – New Features and Upcoming Releases

You can watch Katy Rowe’s Sneak Peek video about what’s coming, here.

Of course, while other companies need to split their focus between traditional genealogy research records and DNA, FamilyTreeDNA does not. Their only focus is genetics. They plan to make advances in every aspect of their products.

FamilyTreeDNA announced a new Help Center which you can access, here. I found lots of short videos and other helpful items. I had no idea it existed.

In 2021, customers began being able to order a combined Family Finder and myDNA test to provide insights into genealogy along with health and wellness

Wellness includes nutrition and fitness insights.

Existing customers either are or will be able to order the myDNA upgrade to their existing test. The ability to upgrade is being rolled out by groups. I haven’t had my turn yet, but when I do, I’ll test and let you know what I think. Trust me, I’m not terribly interested in how many squats I can do anymore, because I already know that number is zero, but I am very interested in nutrition and diet. I’d like to stay healthy enough to research my ancestors for a long time to come.

FamilyTreeDNA announced that over 72,000 men have taken the Big Y test which has resulted in the Y DNA tree of mankind surpassing 50,000 branches.

This is utterly amazing when you consider how far we’ve come since 2002. This also means that a very high number of men, paired with at least one other man, actually form a new branch on the Y haplotree.

The “age” of tester’s Y DNA haplogroups is now often within the 500-year range – clearly genealogical in nature. Furthermore, many leaf-tip haplogroups as defined by the Big Y SNPs are much closer than that and can differentiate between branches of a known family. The Big Y-700 is now the go-to test for Y DNA and genealogy.

Of course, all these new branches necessitate new maps and haplogroup information. These will be released shortly and will provide users with the ability to see the paths together, which is the view you see here, or track individual lines. The same is true for mitochondrial DNA as well.

Y DNA tree branch ages will be forthcoming soon too. I think this is the #1 most requested feature.

On the Mitochondrial DNA side of the house, the Million Mito project has led to a significant rewrite of the MitoTree. As you know, I’m a Million Mito team member.

Here’s Dr. Paul Maier’s branch, for example. You can see that in the current version of the Phylotree, there is one blue branch and lots of “child” branches beneath that. Of course, when we’re measuring the tree from “Eve,” the end tip leaf branches look small, but it’s there that our genealogy resides.

In the new version, yet to be released, there is much more granularity in the branches of U5a2b2a.

To put this another way, in today’s tree, haplogroup U5a2b2a is about 5,000 years old, but the newly defined branches bring the formation of Paul’s (new) haplogroup into the range of about 500 years. Similar in nature to the Y DNA tree and significantly more useful for genealogical purposes. If you have not taken a mitochondrial DNA full sequence test, please order one now. Maybe your DNA will help define a new branch on the tree plus reveal new information about your genealogy.

Stay tuned on this one. You know the Million Mito Project is near and dear to my heart.

2022 will also see much-needed improvements in the tree structure and user experience, as well as the matches pages.

There are a lot of exciting things on FamilyTreeDNA’s plate and I’m excited to see these new features and functions roll out over the next few months.

Just the Beginning

The three days of RootsTech 2022 may be over, but the content isn’t.

In fact, it’s just the beginning of being able to access valuable information at your convenience. The vendor booths will remain in the Expo Hall until RootsTech 2023, so for a full year, plus the individual instructor’s sessions will remain available for three years.

In a few days, after I take a break, I’ll publish a full list of DNA sessions, along with links for your convenience.

Thank You Shout Outs

I want to say a HUGE thank you to RootsTech for hosting the conference and making it free. I specifically want to express my gratitude to the many, many people working diligently behind the scenes during the last year, and frantically during the past three days.

Another huge thank you to the speakers and vendors whose efforts provide the content for the conference.

And special thanks to you for loving genealogy, taking your time to watch and learn, and for reading this blog.

Preserving Items for Future DNA Testing – Teeth, Stamps, Envelopes, Hats, Hair and More

I often receive questions about testing items from deceased people. Is that type of testing available, and is it successful?

The answer is some shade of grey depending on several factors.

So, let’s start with no and work our way up!

NO

Today for the normal air-breathing human, testing items for DNA in a commercial lab for genealogical purposes is not yet feasible. In part, this is due to the labor-intensive extraction costs plus the fact that often, when DNA is able to be retrieved, it’s not of sufficient quality to pass the stringent guidelines of the testing companies.

Compounding that issue is one of consent. How does the testing company actually know the item is from someone deceased AND that you have the legal right to request the specified service?

There are other problems too.

How do you know the stamp was really licked by your ancestor or the intended person and not by the person at the post office, or a family member or neighbor? You don’t.

How do you know the DNA retrieved is actually that of your ancestor or intended person and not contaminant DNA from someone else? You don’t.

And yes, I know there are companies that enter our periphery from time to time that advertise the ability to provide this service. So far, I’ve not seen consistent success which is why these companies don’t stay around long. It’s very expensive, for them and for the consumer, just to try. Regardless of the outcome.

The Technology

The intricate extraction methodology and processing is the same technology used to process forensic samples from crime scenes or to identify unknown deceased people.

Clearly, in some cases, it’s technically possible. However, remember that this type of work requires a special lab, costs in the ballpark of $2000 per sample, or more, and the results often need to be compared in a database environment that accepts partial or degraded results.

My advice – don’t even attempt this now unless you have LOTS of whatever it is from the deceased person and don’t mind sacrificing some of it, along with some big $$, and be prepared to receive no result. I’ve now tried this twice without success.

However, this isn’t the situation with someone recently deceased.

YES

While processing DNA from the recently deceased is not a commercially available service today, it’s sometimes possible.

You need to collect a DNA sample immediately after death using a swab kit. If you’re like me, you always have a DNA kit at home, but you might not be like me or you might not be at home.

You can call FamilyTreeDNA and have them overnight a kit to you or the funeral home, or you can go to the closest pharmacy and purchase an Identigene DNA kit. This brand includes swabs. Ask the mortician to swab the inside of the cheeks of the deceased. (Do NOT send the swabs in the kit to Identigene – you’re only using their swabs in order to send it to FamilyTreeDNA.)

Hopefully, there is no denture adhesive present, as that interferes with DNA processing.

While swabbing is recommended prior to embalming, if embalming has already occurred, ask them to swab anyway. The worst thing that will happen is that it won’t work. It’s worth a try.

I wrote about the process, here.

Clearly, with a swab kit, you’ll need a DNA company that uses swabs to do the processing. That eliminates both Ancestry and 23andMe which use spit kits, leaving as candidates only FamilyTreeDNA and MyHeritage. Fortunately, you can upload DNA files from one to the other.

MAYBE

Some things fall in-between yes and no, meaning taking a swab of a recently deceased person to process at FamilyTreeDNA and attempting to process an artifact.

For example, blood cards or tissue samples fall into this category. In this case, the challenge will be finding a lab that will accept that item.

FamilyTreeDNA may, but you’ll need to contact them in advance as it’s on a case-by-case basis.

Candidate Items

Please keep in mind that all items can be contaminated by handling. To handle, wear sterile gloves and use sterile tweezers. Your goal is to avoid contamination by handling or storage.

We’ll discuss storage and preservation in the next section.

Here’s a list of common candidate items and my comments:

Item Comments
Hair Can be contaminated. May not include the follicle which is your best bet for autosomal DNA. While mitochondrial DNA is most typically extracted from hair, using forensic methods, in some cases, autosomal can be extracted as well.
Envelopes and stamps High probability of contamination. Special processing needs to be utilized due to the adhesive which in some cases is animal-based which means it contains animal DNA.
Teeth Should be in good shape and not have cavities, meaning baby teeth are better candidates than extracted teeth. Normally, adult teeth aren’t extracted without a reason. Don’t throw anything away though.
Hearing aids Hearing aids often contain ear wax and skin cells and make good candidates.
Glasses nose pads The nose pad or metal connecting the nose pad to the glasses frame sometimes harbors skin cells.
Dentures Possible candidates although adhesive interferes with DNA as does soaking denture in cleaning solutions.
Electric razors Excellent candidates since residue held in razors generally contains skin cells. However, be sure your relative is the only person who used the razor. Contact the lab for instructions before extracting the contents.
Blood cards and tissue samples Excellent source but the lab needs to be contacted about whether they accept this type of sample and how to send it safely. Blood and tissue samples may be held by a medical facility if the person was hospitalized, received treatment, or a post-mortem was performed.
Hats, sweaty items, etc. Possible candidates but it depends on the item, its age, and condition. Contact the lab with specifics. With hats, check for embedded hairs which may be a better source than the hat itself.
Used Kleenex type tissue If you’re positive that the tissue was used by the target person, this is a great source of DNA.
Toothbrush Sometimes, but bacteria can be an issue. Doesn’t hurt to save a toothbrush after allowing to dry completely
Fingernail and toenail clippings Clippings are a great source of DNA. Be sure to check clippers, as some have little “catchers” built-in. Also check the drawer where clippers are stored, assuming there is only one individual using those clippers.
Travel bag If your relative traveled from time to time, check the bag in their suitcase that held their personal items. You never know what you might find. Mine holds many DNA-rich items and yours probably does too.

If your relative passed away from something communicable, you need to take that into consideration.

Storage and Preservation Guidelines

While this type of DNA processing service isn’t commercially available as an off-the-shelf service yet today, as technology improves and prices reduce, I feel confident it will be a viable, readily-available service someday. I’ve been saying that for years now, and I just hope someday isn’t too far in the future.

Your challenge is to keep your sample of whatever it is in good condition, so it doesn’t degrade irrecoverably while you are waiting.

  • NEVER store items in plastic including ziplocks or baggies. Plastic prevents air circulation and encourages mold.
  • NEVER use any type of tape or adhesive.
  • DO store each item individually in paper, like an envelope, preferable acid-free paper.
  • If you store an item in fabric, DO wash the fabric first to remove dye, stabilizers and dirt as well as DNA residue from other people. Handle the fabric with sterile gloves after washing.
  • DON’T store the item against wood and not in a cedar chest. Wood contains tannins which are acids that stain and leach into other items.
  • DON’T store the item in the sun, a hot attic or humid basement.
  • DO store the item in a safe, dark location in a temperature-controlled area of your home.
  • DO label the container the item is stored in.

I have several items from my father and grandfather that I’m keeping with the hope of someday being able to utilize them. I have them stored individually in an acid-free envelope, in a small train case, buffered by acid free tissue paper, with nothing else touching the envelope, in my closet.

I’ve also enclosed a note for my daughter, just in case she finds those one day and wonders what they are and why they are packaged in that manner.

Don’t Throw It Away

Let’s say you’ve already done DNA testing on your parent, then they pass away.

As you go through their things, you see hairbrushes and razors and maybe even find a tissue in a nightgown pocket.

You think about how those items would be good for DNA testing and you’re glad you already did that. That means you don’t need to save those things, right? Wrong!

DON’T throw those items away. They’re treasure. There may be new vendors in the future, new companies that process and utilize DNA. There will assuredly be advances in science and new products, and you may wish you had those DNA sources.

I saved my Mom’s hairbrush and Kleenexes from her bathrobe pocket for this exact reason. She lived alone and no one else would have used those items.

Complicating Circumstances

Biological processes accelerate and degrade DNA.

For example, heat.

The heat of modern-day cremations destroys all DNA, even though residual bone fragments are left.

Cold, meaning freezing, would typically preserve DNA, unless a repeated freeze/thaw cycle is involved. In other words, don’t store those teeth in a frost-free refrigerator. I know someone who froze something in an ice cube tray and suffice it to say that a guest received a VERY unexpected surprise one hot summer day. In another instance, a power failure caused everything in a freezer to be thrown away. Freezing is generally not the best choice.

If your ancestor died in a fire, or the home burned but some items were preserved – maybe.

If flooding or water was involved, again, think mold and rapid degradation. Dry those items but without high heat and not in a dryer. If you’re dealing with sewer water, dispose of the items.

The bottom line is this – if there’s enough of an item left to see and identify, other than cremains, there’s enough to preserve, just in case.

Truly, you never know. The best you can do is to begin preservation now and work with what you have.

Staying on the Right Side of the Law

I’m not a lawyer, but I do know that there are required legal procedures to exhume remains for testing. Those laws and procedures vary by location.

Do not try this at home. Contact a lawyer in the jurisdiction where the person you hope to test is buried and be prepared to convince at least five people that your need is pressing and justifiable:

  • The lawyer (bring a large check)
  • Other family members, ALL of whom will likely be required to sign and notarize their agreement
  • A judge who will ultimately decide
  • The coroner or other individual to arrange exhumation and take the sample
  • A lab to process the sample and if it’s not your DNA testing lab, agreement from your DNA lab to allow your sample to be uploaded

You’ve probably figured out why you never see anyone discussing having exhumed their dearly departed for testing. The hoops are many and the process is exorbitantly complex and expensive. Just moving a grave a mile or so down the road when a cemetery was being permanently flooded, without getting a court order or taking a biological sample cost a friend in excess of $20,000 several years ago.

Alternate Strategies

If you’re seeking the Y DNA or mitochondrial DNA of that ancestor, another family member appropriately descended may be able to serve as a proxy. Work your way up the tree to find test candidates and create a DNA Pedigree Chart.

Males inherit their father’s Y chromosome along with their surname. Everyone received their mother’s mitochondrial DNA, but only females pass it on.

Autosomal DNA, at least in part can sometimes be inferred by matching with other people from the same side through family matching, or conversely, not sharing a match with someone that you know is from either your paternal or maternal side on the same segment.

You can read more about how different kinds of DNA is passed to descendants, here.

Summary

Today, testing most artifact items isn’t a viable strategy to retrieve DNA, but there are some notable exceptions. Alternate testing strategies may prove more fruitful

However, taking appropriate measures to preserve these items for future testing is a great strategy. The worst that can happen is that it doesn’t work. You’ll never know if you don’t take those preservation steps today.

The best outcome, of course, is that one day your ancestor’s DNA will be able to assist your genealogy. I can hardly wait!

RootsTech Launches “Relatives at RootsTech” App – Are We Related?

FamilySearch has launched their updated “Relatives at RootsTech” app just in time for RootsTech’s opening day, February 18th.

You can see how this works for yourself, here, AND see if we are related, according to the trees at FamilySearch. Click on this link and find out IF we’re related and how distantly. Starting February 18th, we’ll be able to find out HOW we’re related.

And yes, before you say it, those trees aren’t always accurate, but one of three situations will occur:

  • The connection is accurate.
  • It’s not accurate and you can correct it as a service to yourself all that follow.
  • The tree contains new information that will serve as a hint for you and lead to either condition one or two, above.

When you click on my link, you’ll be prompted to set up or update your own account, or you can simply enter www.familysearch.org/en/connect.

Please be sure to register for Full Access RootsTech, for free, while you’re there.

OK, here’s how this works.

Connect

You can click on “Join Event,” or you can scroll down for more info about other things you can do.

More Info

You can see who else shares a surname.

You can see how Relatives at RootsTech works.

You can see how many other people have signed up for this app and where they live.

On Valentines Day, more than 360,000 people had signed up for RootsTech itself, and that number is rising rapidly now. Last year, attendance reached over 1 million and this year’s signups are slightly ahead of last year’s at this time.

I hope all of the attendees sign up for Relatives at RootsTech so we can all see how we’re related.

Join Event

When you click on “Join Event,” you’ll be promoted to either join FamilySearch or update your profile to grant permission for FamilySearch to display your connection to your cousins.

You can personalize the experience by uploading a photo.

I uploaded a portrait so people will recognize me. We can’t see each other in person this year, but we can at least smile when we see our cousins’ photos.

You’ll be asked for some pretty basic information.

Starting on February 18th, you’ll be able to see exactly how you’re related to your cousins.

In the couple hours it took me to write this article, the total participants signed up for the Relatives at RootsTech app increased by more than 2,500 to 15,640.

Register for RootsTech

Be sure to register for RootsTech when you’re updating your profile.

RootsTech is totally free with a dynamite lineup. Why wouldn’t anyone sign up for All Access?

Keynotes

One of the other generous speakers, Dr. Penny Walters, created this collage of the keynote speakers including Thais Pacholek, Molly Yeh, Azumah Nelson, Diego Torres, Matthew Modine, Apollonia Poilane, Maysoon Zayid, Elder Ulisses Soares and his wife, Sister Rosana Soares.

#chooseconnection

RootsTech encourages us to #chooseconnection and see how we’re connected to each other, to history and to our homeland. Ironically, I didn’t know this when I was creating my sessions. My session, “Native American DNA – Ancient and Contemporary Maps” speaks to connection in just about every way possible. I hope you will join me for this session and several more too.

The speaker session agenda will be released soon, and you will be able to create an individual playlist.

After you update your account so that you can connect with others, you’ll be prompted to share. I posted this link to both Facebook and Twitter, and of course, I’m sharing with you here.

Beginning on February 18th and continuing beyond RootsTech, until March 25th, you’ll be able to see exactly how you are related to your cousins who have also signed up and opted in!

I have to tell you, several people have already commented, telling me we are cousins. I didn’t know we shared ancestors. I’m having so doggone much fun!

So, are we related?

Here’s the link to see for yourself. Let me know. I can’t wait to find out exactly how.

I’m starting a RootsTech friends spreadsheet to track exactly how I’m related to whom. Some of you HAVE to have info that I don’t and vice versa. That’s what sharing is all about, and maybe our DNA matches too!

Maybe you’d like to start a spreadsheet and keep track too. Be sure to collect contact information so you can connect after the conference. How many cousins will you find at RootsTech?

Are you doing anything special to prepare? Please share in the comments and let’s make this the best RootsTech ever.
