More Ancient DNA Samples For Comparison

Felix Chandrakumar has prepared and added three additional ancient DNA kits to GedMatch.  Thanks Felix!  This is a wonderful service you’re performing for the genetic genealogy community!

  • The Linearbandkeramik (LBK) sample, also referenced as “Stuttgart,” reflecting where it was discovered in Germany.  This individual was an early farmer dating from about 7,500 years ago and was one of the samples analyzed for the paper, Ancient genomes suggest three ancestral populations for present-day Europeans. Kit F999916
  • The La Brana-Arintero sample from Leon, Spain, about 7000 years old, represents a pre-agricultural European human genome – in other words, before the agriculturists from the Near East arrived. In an article at Science Daily, they have reconstructed his face. Original academic article available here. Kit F999915
  • The Mal’ta sample, from Siberia, about 24,000 years of age. The results were discussed in article, Native American Gene Flow – Europe?, Asia and the Americas, and the original article is available here. Kit F999914

These kits, along with the ones listed earlier, give us the opportunity to compare our own DNA with that of ancient people in specific populations.  It’s like taking a step back in time and seeing if we carry any of the same small segments as these people did – suggesting of course that we descend from the same population.

This Ancient European DNA map by Richard Stevens shows the European locations where ancient DNA has been retrieved.

Recent discussion has focused on determining what matches to these specimens actually mean to genetic genealogists today.  We obviously don’t have that answer at this point.  We know that, due to their age, these samples are not close relatives in terms of genealogy generations, but in some cases, we find that we have matches far larger than one would expect to be found utilizing the 50% washout per generation math.

Endogamy, especially in a closed population such as Native Americans is certainly one explanation.  That doesn’t explain the European matches however – either to Anzick, the Native American specimen, nor Europeans to the European samples.  The higher no-call rate in the autosomal files can contribute as well, but wouldn’t account for all matches.  In some cases, maybe everyone carries the same DNA because the population carries that DNA in very high rates – but the population carries the DNA in very high rates because the ancient ancestors did as well…so this is a bit of circular logic.  All that said, we’re still left wondering what is real and what is Memorex, so to speak?

Ancient DNA is changing our understanding of the human past, and that of our ancestors.  It allows us a connection to the ancient people that is tangible, parts of them found in us today, as unbelievable as it seems.

When Svante Paabo discovered that modern Europeans all carry pieces of Neanderthal DNA, he too was struck by what I’ll call “the disbelief factor,” thinking, of course, that it can’t possibly be true.  He discussed this at length in his book, Neanderthal Man, In Search of Lost Genomes, and the steps taken by his team to prove that the matches weren’t in error or due to some problem with the ancient genome reconstruction process.  Indeed, all Europeans and Asians carry both Neanderthal and Denisovan DNA, and by the same process of the DNA being carried by the entire population at one point, which must be the avenue for contemporary humans to carry other ancient DNA as well.  As we find individual matches to small pieces of DNA with these matches, how much of that is “real” versus convergence or a result of no-calls in the ancient files?

In that vein, I find this article from Dienekes Anthropology Blog quite interesting,  found in the ASHG Titles of Interest from the upcoming Conference in October in San Diego, CA.

Reducing pervasive false positive identical-by-descent segments detected by large-scale pedigree analysis. E. Y. Durand, N. Eriksson, C. Y. McLean.

“Analysis of genomic segments shared identical-by-descent (IBD) between individuals is fundamental to many genetic applications, from demographic inference to estimating the heritability of diseases. A large number of methods to detect IBD segments have been developed recently. However, IBD detection accuracy in non-simulated data is largely unknown. In principle, it can be evaluated using known pedigrees, as IBD segments are by definition inherited without recombination down a family tree. We extracted 25,432 genotyped European individuals containing 2,952 father-mother-child trios from the 23andMe, Inc. dataset. We then used GERMLINE, a widely used IBD detection method, to detect IBD segments within this cohort. Exploiting known familial relationships, we identified a false positive rate over 67% for 2-4 centiMorgan (cM) segments, in sharp contrast with accuracies reported in simulated data at these sizes. We show that nearly all false positives arise due to allowing switch errors between haplotypes when detecting IBD, a necessity for retrieving long (> 6 cM) segments in the presence of imperfect phasing. We introduce HaploScore, a novel, computationally efficient metric that enables detection and filtering of false positive IBD segments on population-scale datasets. HaploScore scores IBD segments proportional to the number of switch errors they contain. Thus, it enables filtering of spurious segments reported due to GERMLINE being overly permissive to imperfect phasing. We replicate the false IBD findings and demonstrate the generalizability of HaploScore to alternative genotyping arrays using an independent cohort of 555 European individuals from the 1000 Genomes project. HaploScore can be readily adapted to improve the accuracy of segments reported by any IBD detection method, provided that estimates of the genotyping error rate and switch error rate are available.”

I’m pleased to see that they are addressing smaller segments, in the 2cM-4cM range, because those are the ranges some are finding in matches to these ancient genomes.  A few matches are even larger.

Of course, all of this ancient matching has caused an upsurge in interest in the cultures and populations of these ancient people whose DNA we carry.

I find this graphic very interesting from the paper, Toward a new history and geography of human genes informed by ancient DNA, just published this month, by Joseph Pickrell and David Reich.  This map, which shows the population movement into and out of geographic regions of the world in the past, is especially interesting in that several back migrations are shown into Africa.  I’ve never seen the “history of the world in population migration” summed up quite so succinctly before, but it helps us understand why certain DNA is found in specific locations.

As we find and fully sequence additional ancient DNA specimens, we’ll be able to better understand how the ancient populations were related to each other, and then, how we descend from each of them.

This is a fascinating age of personal discovery!

Ancient DNA Matching – A Cautionary Tale

egg

I hope that all of my readers realize that you are literally watching science hatch.  We are on the leading, and sometimes bleeding edge, of this new science of genetic genealogy.  Because many of these things have never been done before, we have to learn by doing and experimenting.  Because I blog about this, these experiments are “in public,” so there is no option of a private “oops.”  Fortunately, I’m not sensitive about these kinds of things.  Plus, I think people really enjoy coming along for the ride of discovery.  I mean, where else can you do that?  It’s really difficult to get a ride-along on the space shuttle!

One of the best pieces of advice I ever got was from someone who was taken from my life far too early.  I had made a mistake of some sort…don’t even remember what…and he gave me a card that said, “The only people who don’t make mistakes are the people who don’t try.”

This isn’t an “oops” moment.  More like an “aha” moment.  Or more precisely, a “huh” moment.  It falls in the “Houston, we’ve got a problem” category.

So, this week’s new discovery is that there seems to be some inconsistency in the matching to the Anzick kit at GedMatch.  Before I go any further, I want to say very clearly that this is in no way a criticism of anyone or any tool.  Every person involved is a volunteer and we would not be making any of these steps forward, including a few backwards, without these wonderful volunteers and tools.

I have reached out to the people involved and asked for their help to unravel this mystery, and I’m sharing the story with you, partly so you can understand what is involved, and the process, partly so that you don’t inadvertently encounter the same kinds of issues and draw unrealistic or incorrect conclusions, and partly so you can help.  If there has been any common theme in all of my articles in the past week or so about the ancient DNA articles, it has been that we really don’t understand what conclusions to draw yet…and we still don’t.  So don’t.

Let’s introduce the players here.

The Players

Felix Chandrakumar has very graciously prepared the various ancient DNA files and uploaded them to GedMatch.  Felix has written a number of DNA analysis tools as well.

John Olson is one of the two volunteers who created and does everything at Gedmatch, plus works a full time job.  By the way, in case you’re not aware, this is a contribution site, meaning they depend on your financial contributions to function, purchase hardware, servers, etc.  If you use this site, periodically scroll down and click on the donate button.  We, as a community, would be lost without John and his partner.

David Pike is a long time genetic genealogist who I have had the pleasure of working with on a number of Native American and related topics over the years. He also has created several genetic genealogy tools to deal with autosomal DNA. David prepared the Anzick files for some private work we were doing several months ago, so he has experience with this DNA as well.  Dr. Pike has a great deal of experience analyzing the endogamous population of Newfoundland, which is also admixed with Native Americans.

Marie Rundquist, also a long time genetic genealogist who specializes in both technology and Acadian history along with genetic genealogy.  Acadians are proven to be admixed with Native Americans.  Marie shares my deep interest and commitment to Native American study and genetics.  Furthermore, Marie and I also share ancestors and co-administer several related projects.   As you might imagine, Marie and I took this opportunity immediately to see if she and her mother share any of Anzick’s segments with me and my mother.

So, a big thank you to all of these people.

The Mystery

When Felix originally e-mailed me about the Anzick kit being uploaded to GedMatch, as you might imagine, I stopped doing whatever I was doing and immediately went to study Anzick and the other ancient DNA kits.

I wrote about this experience in the article, “Utilizing Ancient DNA at GedMatch.”

As part of that process, I not only ran Anzick’s kit utilizing the “one to many” option, I also compared my own kit to Anzick’s.  My proven Native lines descend through my mother, so I ran her kit against Anzick’s as well, at the same thresholds, and I combined the two results to see where mother and I overlapped.

I showed these overlaps in the article, along with which genealogy lines they matched by utilizing my ancestor matching spreadsheet.

Everything was hunky dory…for then.

Day 2

The next day, I received a note from Felix that the Anzick kit may not have been fully tokenized at GedMatch previously, so I reran the Anzick “one to all” comparison and wrote about those results in the second article, “Analyzing the Native American Clovis Ancient Results.”  Because it wasn’t yet fully processed originally, the second results produced more matches, not fewer.

I wasn’t worried about the one to one comparison of Anzick to my own kit, because one to one comparisons are available immediately, while one to many comparisons are not, per the GedMatch instructions.

“Once you have loaded your data, you will be able to use some features of the site within a minute or so. Additional batch processing, which usually takes a couple of days, must complete before you can use some of the tools comparing you to everyone in the data pool.”

So, everything was stlll hunky dory.

Day 3

The next day, Marie and I had a few minutes, sometime between 2 and 3AM, and no, I’m not kidding.  We decided to compare results.  I decided it would be quicker to run the match again at GedMatch than to sort through my Master spreadsheet, into which I had copied the results and added other information.  So, I did a second download of the Anzick comparison, utilizing the exact same thresholds (200 SNPs, 2cM, and the rest left at the default,) and added them to a spreadsheet that Marie and I were passing back and forth, and sent them to Marie.  I noticed that there seemed to be fewer matches, but by then it was after 3AM and I decided to follow up on that later.

Not so hunky dory…but I didn’t know it yet.

Day 4

The following day, Dr. Ann Turner (MD), also a long-time genetic genealogist, posted the following comment on the article.

“These results, finding “what appear to be contemporary matches for the Anzick child”, seemed very counter-intuitive to me, so I asked John Olson of GEDMatch to look under the hood a bit more. It turns out the ancient DNA sequence has many no-calls, which are treated as universal matches for segment analysis. Another factor which should be examined is whether some of the matching alleles are simply the variants with the highest frequency in all populations. If so, that would also lead to spurious matching segments. It may not be appropriate to apply tools developed for genetic genealogy to ancient DNA sequences like this without a more thorough examination of the underlying data.”

I had been aware of the no-calls due to the work that Dr. David Pike did back in March with the Anzick raw data files, but according to David, that shouldn’t affect the results.

Here’s what Dr. Pike, a Professor of Mathematics, had to say:

“Yes, these forensic samples have very high No-Call rates, which may give rise to more false matches than we would normally experience.  Also, be aware that false matches are more prone to occur when using reduced thresholds (such as 100 SNPs and 1 cM) and unphased data.  In this case I don’t think there’s any way around using low thresholds, simply because we’re looking for very small blocks of DNA (probably nobody alive today will have any large matching blocks with the Anzick child).

On the assumption that there will be a nearly constant noise ratio, meaning that most people will have about the same number of false matches with the Anzick child, those who are from the same gene pool should have an increased number of real matches.  So by comparing the total amount of matching DNA, it ought to be possible to gauge people’s affinity with Anzick’s gene pool.”

Here are Felix’s comments about no-calls as well:

“Personally, no calls are fine as long as there are more SNPs matching above the threshold level because the possibility of errors occurring exactly on no-call positions for all the matches in all their matching segments is impossible.”

Courtesy of Felix, we’ll see an example of how no calls intersperse in  a few minutes.

If no-calls were causing spurious matches in the Anzick kit, you’d expect to see the same for the other ancient DNA kits.  I know that the Denisovan and Neanderthal kits also have many no-calls, and based on the nature of ancient DNA, I’m sure all of them do.  So, if no calls are the culprit, they should be affecting matches to the other kits in the same way, and they aren’t.

Hunky-doryness is being replaced by a nonspecific nagging feeling…same one I used to get when my teenagers were up to something.

Day 5

A day or so later, Felix uploaded file F999913 to replace F999912 with the complete SNPs from all of the companies.  The original 999912 kit only included the SNP locations utilized by Family Tree DNA.  Felix added the SNPs utilized by 23and Me not utilized at Family Tree DNA, and the ones from Ancestry as well.  This is great news for anyone who tested at those two companies, but I had utilized my kit from Family Tree DNA, so for me, there should be no difference at all.

I later asked Felix if he had changed anything else in the file, and he said that he had not.  He provided extensive documentation about what he had done.

I waited until kit F999912 was deleted to be sure tokenizing was complete for F999913 and re-compared the data again.  As expected, Anzick’s one to all had more matches than before, because additional people were included due to the added SNPs from 23andMe and Ancestry.

Some of Anzick’s matches are in the contemporary range, at 3.1 estimated generations, with the largest cM segment of 22.8 and total cMs of 202.8.

anzick 999913

These relatively large matches cause Felix to question whether the sample is actually ancient, based on these relatively large segments.  I addressed my feelings on this in the article, Ancient DNA Matches – What Do They Mean?

Marie and Dr. Pike, both with extensive experience with admixed populations addressed this as well.  Marie commented,

“Native DNA found in the Anzick sample hasn’t changed all of that much and may still be found in modern, Native American populations, and that if people have Native American ancestry, they’ll match to it.”

Dr. Pike says:

“I agree with Marie on this… within endogamous populations, there is an increased likelihood of blocks of DNA being preserved over lengthy time frames.  Moreover, even if a block of DNA gets cut up via recombination, within an endogamous population the odds of some parts of the block later reuniting in a person’s DNA are higher than otherwise.  And it exaggerates the closeness of [the] relationship that gets predicted when comparing people.

I have seen something similar within the Newfoundland & Labrador Family Finder Project, whereby lots of people are sharing small blocks of DNA, likely as a result of DNA from the early colonists still circulating among the modern gene pool.

As an anecdotal example, I have a semi-distant relative (with ancestry from Newfoundland) at 23andMe who shares 3 blocks of DNA with my father, 2 with my mother and 5 five me.  As you can imagine, the relative is predicted to be a closer cousin to me than she is to either of my parents!

It doesn’t take an endogamous or isolated population to see this effect.

It can also happen in families involving cousin marriages too, although that would be more pronounced and not quite the same thing as we’re discussing with respect to ancient DNA.”

This addition of other companies SNPs should not affect my matches with Anzick because my kits are both from FTDNA and won’t utilize the added SNPs.

However, I ran my and my mother’s matches again, and we had a significantly different outcome than either of the previous times.

I utilized the same threshold for all downloads and those are the only values I changed – 200 SNPs and 2cM, leaving the other values at default, for all Anzick comparisons to my mother and my kits.

I am not hunky-dory anymore.

The Heartburn

These matches, which should be the same in all three downloads, produced significantly different results.

Here are the number of matches at the same threshold comparing me and Mom to the Anzick file:

Me and Anzick

  • original download 999912 – 47 matches
  • second download 999912 – 21 matches
  • 999913 – 35 matches

Mom and Anzick

  • original download 999912 – 63
  • second download 999912 – 37
  • 999913 – 36

And no, the 36 /35 that mom and I have for 999913 are not all the same.

Kit Number Matches Between Me, Mother and Anzick
#1-F999912 original download 19
#2-F999912 second download 6
#3-F999913 11

Of those various downloads, the following grid shows which ones matched each other.

#1 to #2 #2 to #3 #1 to #3 All 3
# of Matches 6 2 3 2

So, comparing the first download to the last download, of the 19 original matches, we lost 16 matches.  In the third download, we gained 8 matches and only 3 remained as common matches. So of 30 total matches between my mother, myself and Anzick, in two downloads that should have been exactly the same, only 3 matches held, or 10%.

Obviously, something is wrong, but what, and where?  At that point, I asked Marie to download her and her mother’s results again too, and she experienced the same issue.

Clearly a problem exists someplace.  That’s the question I asked Felix, John and David to help answer.

I realize that this spreadsheet it very long, and I apologize, but I think this issue is much easier to see visually.  I’ve compiled the matches by color and shade to make looking at them relatively easy.

My matches to the Anzick kit are in shades of pink – the first match download being the lightest and the last one to kit F999913 being the darkest.  Mother is green, same shading scheme.

The three columns to the right show the matching segments for each download – shaded in green.  You can easily see which ones line up, meaning which ones match consistently across all three downloads.  There aren’t many.  They should all match.

anzick me mom problem

Obviously this led to many questions that I asked of the various players involved.

My first thought was that perhaps a matching algorithm change occurred in GedMatch, but John assured me that he had made no changes.

Next question was whether or not Felix changed something other than adding the 23andMe and Ancestry SNPs.  He had not.

Felix was kind enough to explain about bunching and to do some analysis on the files.

“When you have low thresholds, make sure you don’t allow errors. For example, at 200 SNPs, the default ‘Mismatch Evaluation window’ and in GEDMatch is same as SNP threshold and ‘Mismatch-Bunching limit’ is half of mismatch evaluation window. So, at 200 cM, you are allowing 1 error every 100 SNPs apart from no-calls.

I did some analysis on your phased mother’s kit, PF6656M1 so that at least we know that it is an IBD for one generation.  The spreadsheet (below) are segments I found at 2 cM/200 SNPs threshold without allowing any errors.”

Kit PF6656M1 is one single kit created by phasing my data against my mother’s so that we don’t have to run both kits.  I had not utilized the phased kit previously, so I was interested in his results.

felix anzick

The results above confirm chromosome matches, 2, 17, 19 and 21, but introduce a new match on chromosome 4.  This match was present in the original download, but not in the second or third download, so once again, we have disparate data, except the thresholds Felix used were at a different level.

One of the more interesting things that Felix included is the no-call match information, the three columns to the right.  I want to show what the no-calls look like.  There are not huge segments that are blank and are being called as matches because they are no-calls, when they shouldn’t be.  No calls are scattered like salt and pepper.  In fact, no calls happen in every kit and they are called as matches so they don’t in fact disrupt a valid match string, potentially making it too small to be considered a match.  Of course, ancient DNA has more no-calls that contemporary DNA kits.

Below are the first few match positions from chromosome 2 where mother, Anzick and I have a confirmed match across all downloads.  The genotype shows you that both kits match.

felix no calls

For consistency, I ran the same kits that Felix ran, PF6656M1 and F999913, with the original thresholds I had used, and found the following:

Chr Start Location End Location Centimorgans (cM) SNPs
1 31358221 33567640 2.0 261
2 218855489 220351363 2.4 253
4 1957991 3571907 2.5 209
5 2340730 2982499 2.3 200
17 53111755 56643678 3.4 293
19 46226843 48568731 2.2 250
21 35367409 36761280 3.7 215

This introduces chromosomes 1 and 5, not shown above.   The chromosome 1 match was shown in the first and second download, but not the third, and the chromosome 5 match was shown in the first download only, but not the second or third.

Can you see me beating my head against the wall yet??

In a fit of apparent insanity, I decided to try, once again, an individual download of Anzick compared to my mother and to me, but not utilizing the phased kit – the original F6656 and F9141, and at the original thresholds, for consistency.  I wanted to see if the matches were the same now as they were a day or so ago.  They should be exact.  This first one is mine.

me second 999913

What you should see are two identical downloads.  I have color coded the rows so you can see easily – and what you should see are candy-cane stripes – one red and one white for every match location.

That’s not what we’re seeing.  The kits are the same, the match parameters are the same, but the results are not.  Once again, the downloads don’t match.

I did another match on mother and Anzick, and her results were consistent between the first and second match to kit F999913.

mom second 999913

The begs the next question.  Have mother’s results always been consistent, suggesting a problem with my kit?

I sorted all of her downloads, and no, they are not consistent, except for the first and second download matches to kit F999913, shown above.  The inconsistencies show up in both mother and my kits, although not in the same locations.  Recall also that Marie had the same issue.

In Summary

Something is wrong, someplace.  I know that sounds intuitively obvious – NOW.  But it wasn’t initially and I wouldn’t even have suspected a problem without running the second and third downloads, quite unintentionally.  Most people never do that, because once you’ve done the match, you have no reason to ever match to that particular person again.  Given that, you’ll never know if a problem exists.

So, the only Anzick GedMatch matches I have any confidence in at all, at this point, are the few that are consistent between all of the downloads, and I didn’t add the fourth download into the mix.  I don’t’ see any point because I’ve pretty much concluded that until we determine where the issue resides, that I won’t have confidence in the results.

The next question that comes to mind, and that I can’t answer, is whether or not this issue is present in contemporary matching kits – or if this is somehow an ancient DNA problem – although I don’t know quite how that could be – since matching is matching.

I haven’t saved any matches that I’ve run to other people in spreadsheets, so I can’t go back and see if a GedMatch match today produces the exact same results as a previous match.

Clearly there is no diagnosis or solution in this summary.  We are not yet hunky dory.

What You Can Do

  1. Run your Anzick and ancient DNA matches multiple times, at the same exact thresholds, on different days, to see if your results are consistent or inconsistent. Same kit, same thresholds, the results should be identical.
  2. If you have some saved GedMatch matches with contemporary people, and you are positive of the match thresholds used, please run them again to see if the results are identical. They should be.
  3. No drawing of or jumping to conclusions, please, especially about ancient DNA:) It’s a journey and we are fellow pilgrims!

If your results are not consistent, please document the problem and let the appropriate person know.  I don’t want to overwhelm John at GedMatch but I’m concerned at this point that the problem may not be isolated to ancient DNA matching since the issue seems to extend to Marie’s results as well.

If your results, especially to Anzick, from previous matches to now are consistent, that’s worth knowing too.  Please add a comment to that effect.

Thoughts and ideas are welcome.

Ancient DNA Matches – What Do They Mean?

The good news is that my three articles about the Anzick and other ancient DNA of the past few days have generated a lot of interest.

The bad news is that it has generated hundreds of e-mails every day – and I can’t possibly answer them all personally.  So, if you’ve written me and I don’t reply, I apologize and  I hope you’ll understand.  Many of the questions I’ve received are similar in nature and I’m going to answer them in this article.  In essence, people who have matches want to know what they mean.

Q – I had a match at GedMatch to <fill in the blank ancient DNA sample name> and I want to know if this is valid.

A – Generally, when someone asks if an autosomal match is “valid,” what they really mean is whether or not this is a genealogically relevant match or if it’s what is typically referred to as IBS, or identical by state.  Genealogically relevant samples are referred to as IBD, or identical by descent.  I wrote about that in this article with a full explanation and examples, but let me do a brief recap here.

In genealogy terms, IBD is typically used to mean matches over a particular threshold that can be or are GENEALOGICALLY RELEVANT.  Those last two words are the clue here.  In other words, we can match them with an ancestor with some genealogy work and triangulation.  If the segment is large, and by that I mean significantly over the threshold of 700 SNPs and 7cM, even if we can’t identify the common ancestor with another person, the segment is presumed to be IBD simply because of the math involved with the breakdown of segment into pieces.  In other words, a large segment match generally means a relatively recent ancestor and a smaller segment means a more distant ancestor.  You can readily see this breakdown on this ISOGG page detailing autosomal DNA transmission and breakdown.

Unfortunately, often smaller segments, or ones determined to be IBS are considered to be useless, but they aren’t, as I’ve demonstrated several times when utilizing them for matching to distant ancestors.  That aside, there are two kinds of IBS segments.

One kind of IBS segment is where you do indeed share a common ancestor, but the segment is small and you can’t necessarily connect it to the ancestor.  These are known as population matches and are interpreted to mean your common ancestor comes from a common population with the other person, back in time, but you can’t find the common ancestor.  By population, we could mean something like Amish, Jewish or Native American, or a country like Germany or the Netherlands.

In the cases where I’ve utilized segments significantly under 7cM to triangulate ancestors, those segments would have been considered IBS until I mapped them to an ancestor, and then they suddenly fell into the IBD category.

As you can see, the definitions are a bit fluid and are really defined by the genealogy involved.

The second kind of IBS is where you really DON’T share an ancestor, but your DNA and your matches DNA has managed to mutate to a common state by convergence, or, where your Mom’s and Dad’s DNA combined form a pseudo match, where you match someone on a segment run long enough to be considered a match at a low level.  I discussed how this works, with examples, in this article.  Look at example four, “a false match.”

So, in a nutshell, if you know who your common ancestor is on a segment match with someone, you are IBD, identical by descent.  If you don’t know who your common ancestor is, and the segment is below the normal threshold, then you are generally considered to be IBS – although that may or may not always be true.  There is no way to know if you are truly IBS by population or IBS by convergence, with the possible exception of phased data.

Data phasing is when you can compare your autosomal DNA with one or both parents to determine which half you obtained from whom.  If you are a match by convergence where your DNA run matches that of someone else because the combination of your parents DNA happens to match their segment, phasing will show that clearly.  Here’s an example for only one location utilizing only my mother’s data phased with mine.  My father is deceased and we have to infer his results based on my mother’s and my own.  In other words, mine minus the part I inherited from my mother = my father’s DNA.

My Result My Result Mother’s Result Mother’s Result Father’s Inferred Result Father’s Inferred Result
T A T G A

In this example of just one location, you can see that I carry a T and an A in that location.  My mother carries a T and a G, so I obviously inherited the T from her because I don’t have a G.  Therefore, my father had to have carried at least an A, but we can’t discern his second value.

This example utilized only one location.  Your autosomal data file will hold between 500,000 and 700,000 location, depending on the vendor you tested with and the version level.

You can phase your DNA with that of your parent(s) at GedMatch.  However, if both of your parents are living, an easier test would be to see if either of your parents match the individual in question.  If neither of your parents match them, then your match is a result of convergence or a data read error.

So, this long conversation about IBD and IBS is to reach this conclusion.

All of the ancient specimens are just that, ancient, so by definition, you cannot find a genealogy match to them, so they are not IBD.  Best case, they are IBS by population.  Worse case, IBS by convergence.  You may or may not be able to tell the difference.  The reason, in my example earlier this week, that I utilized my mother’s DNA and only looked at locations where we both matched the ancient specimens was because I knew those matches were not by convergence – they were in fact IBS by population because my mother and I both matched Anzick.

Q – What does this ancient match mean to me?

A – Doggone if I know.  No, I’m serious.  Let’s look at a couple possibilities, but they all have to do with the research you have, or have not, done.

If you’ve done what I’ve done, and you’ve mapped your DNA segments to specific ancestors, then you can compare your ancient matching segments to your ancestral spreadsheet map, especially if you can tell unquestionably which side the ancestral DNA matches.  In my case, shown above, the Clovis Anzik matched my mother and me on the same segment and we both matched Cousin Herbie.  We know unquestionably who our common ancestor is with cousin Herbie – so we know, in our family line, which line this segment of DNA shared with Anzick descends through.

ancient compare6

If you’re not doing ancestor mapping, then I guess the Anzick match would come in the category of, “well, isn’t that interesting.”  For some, this is a spiritual connection to the past, a genetic epiphany.  For other, it’s “so what.”

Maybe this is a good reason to start ancestor mapping!  This article tells you how to get started.

Q – Does my match to Anzick mean he is my ancestor?

A – No, it means that you and Anzick share common ancestry someplace back in time, perhaps tens of thousands of years ago.

Q – I match the Anzick sample.  Does this prove that I have Native American heritage? 

A – No, and it depends.  Don’t you just hate answers like this?

No, this match alone does not prove Native American heritage, especially not at IBS levels.  In fact, many people who don’t have Native heritage match small segments?  How can this be?  Well, refer to the IBS by convergence discussion above.  In addition, Anzick child came from an Asian population when his ancestors migrated, crossing from Asia via Beringia.  That Eurasian population also settled part of Europe – so you could be matching on very small segments from a common population in Eurasia long ago.  In a paper just last year, this was discussed when Siberian ancient DNA was shown to be related to both Native Americans and Europeans.

In some cases, a match to Anzick on a segment already attributed to a Native line can confirm or help to confirm that attribution.  In my case, I found the Anzick match on segments in the Lore family who descend from the Acadians who were admixed with the Micmac.  I have several Anzick match segments that fit that criteria.

A match to Anzick alone doesn’t prove anything, except that you match Anzick, which in and of itself is pretty cool.

Q – I’m European with no ancestors from America, and I match Anzick too.  How can that be?

A – That’s really quite amazing isn’t it.  Just this week in Nature, a new article was published discussing the three “tribes” that settled or founded the European populations.  This, combined with the Siberian ancient DNA results that connect the dots between an ancient population that contributed to both Europeans and Native Americans explains a lot.

3 European Tribes

If you think about it, this isn’t a lot different than the discovery that all Europeans carry some small amount of Neanderthal and Denisovan DNA.

Well, guess what….so does Anzick.

Here are his matches to the Altai Neanderthal.

He does not match the Caucasus Neanderthal.  He does, however, match the Denisovan individual on one location.

Q – Maybe the scientists are just wrong and the burial is not 12,500 years old,  maybe just 100 years old and that’s why the results are matching contemporary people.

A – I’m not an archaeologist, nor do I play one…but I have been closely involved with numerous archaeological excavations over the past decade with The Lost Colony Research Group, several of which recovered human remains.  The photo below is me with Anne Poole, my co-director, sifting at one of the digs.

anne and me on dig

There are very specific protocols that are followed during and following excavation and an error of this magnitude would be almost impossible to fathom.  It would require  kindergarten level incompetence on the part of not one, but all professionals involved.

In the Montana Anzick case, in the paper itself, the findings and protocols are both discussed.  First, the burial was discovered directly beneath the Clovis layer where more than 100 tools were found, and the Clovis layer was undisturbed, meaning that this is not a contemporary burial that was buried through the Clovis layer.  Second, the DNA fragmentation that occurs as DNA degrades correlated closely to what would be expected in that type of environment at the expected age based on the Clovis layer.  Third, the bones themselves were directly dated using XAD-collagen to 12,707-12,556 calendar years ago.  Lastly, if the remains were younger, the skeletal remains would match most closely with Native Americans of that region, and that isn’t the case.  This graphic from the paper shows that the closest matches are to South Americans, not North Americans.

anzick matches

This match pattern is also confirmed independently by the recent closest GedMatch matches to South Americans.

Q – How can this match from so long ago possibly be real?

A – That’s a great question and one that was terribly perplexing to Dr. Svante Paabo, the man who is responsible for producing the full genome sequence of the first, and now several more, Neanderthals.  The expectation was, understanding autosomal DNA gets watered down by 50% in every generation though recombination, that ancient genomes would be long gone and not present in modern populations.  Imagine Svante’s surprise when he discovered that not only isn’t true, but those ancient DNA segmetns are present in all Europeans and many Asians as well.  He too agonized over the question about how this is possible, which he discussed in this great video.  In fact he repeated these tests over and over in different ways because he was convinced that modern individuals could not carry Neanderthal DNA – but all those repeated tests did was to prove him right.  (Paabo’s book, Neanderthal Man, In Search of Lost Genomes is an incredible read that I would highly recommend.)

What this means is that the population at one time, and probably at several different times, had to be very small.  In fact, it’s very likely that many times different pockets of the human race was in great jeopardy of dying out.  We know about the ones that survived.  Probably many did perish leaving no descendants today.  For example, no Neanderthal mitochondrial DNA has been found in any living or recent human.

In a small population, let’s say 5 males and 5 females who some how got separated from their family group and founded a new group, by necessity.  In fact, this could well be a description of how the Native Americans crossed Beringia.  Those 5 males and 5 females are the founding population of the new group.  If they survive, all of the males will carry the men’s haplogroups – let’s say they are Q and C, and all of the descendants will carry the mitochondrial haplogroups of the females – let’s say A, B, C, D and X.

There is a very limited amount of autosomal DNA to pass around.  If all of those 10 people are entirely unrelated, which is virtually impossible, there will be only 10 possible combinations of DNA to be selected from.  Within a few generations, everyone will carry part of those 10 ancestor’s DNA.  We all have 8 ancestors at the great-grandparent level.  By the time those original settlers’ descendants had great-great-grandparents – of which each one had 16, at least 6 of those original people would be repeated twice in their tree.

There was only so much DNA to be passed around.  In time, some of the segments would no longer be able to be recombined because when you look at phasing, the parents DNA was exactly the same, example below.  This is what happens in endogamous populations.

My Result My Result Mother’s Result Mother’s Result Father’s Result Father’s  Result
T T T T T T

Let’s say this group’s descendants lived without contact with other groups, for maybe 15,000 years in their new country.  That same DNA is still being passed around and around because there was no source for new DNA.  Mutations did occur from time to time, and those were also passed on, of course, but that was the only source of changed DNA – until they had contact with a new population.

When they had contact with a new population and admixture occurred, the normal 50% recombination/washout in every generation began – but for the previous 15,000 years, there had been no 50% shift because the DNA of the population was, in essence, all the same.  A study about the Ashkenazi Jews that suggests they had only a founding population of about 350 people 700 years ago was released this week – explaining why Ashkenazi Jewish descendants have thousands of autosomal matches and match almost everyone else who is Ashkenazi.  I hope that eventually scientists will do this same kind of study with Anzick and Native Americans.

If the “new population” we’ve been discussing was Native Americans, their males 15,000 year later would still carry haplogroups Q and C and the mitochondrial DNA would still be A, B, C, D and X.  Those haplogroups, and subgroups formed from mutations that occurred in their descendants, would come to define their population group.

In some cases, today, Anzick matches people who have virtually no non-Native admixture at the same level as if they were just a few generations removed, shown on the chart below.

anzick gedmatch one to all

Since, in essence, these people still haven’t admixed with a new population group, those same ancient DNA segments are being passed around intact, which tells us how incredibly inbred this original small population must have been.  This is known as a genetic bottleneck.

The admixture report below is for the first individual on the Anzick one to all Gedmatch compare at 700 SNPs and 7cM, above.  In essence, this currently living non-admixed individual still hasn’t met that new population group.

anzick1

If this “new population” group was Neanderthal, perhaps they lived in small groups for tens of thousands of years, until they met people exiting Africa, or Denisovans, and admixed with them.

There weren’t a lot of people anyplace on the globe, so by virtue of necessity, everyone lived in small population groups.  Looking at the odds of survival, it’s amazing that any of us are here today.

But, we are, and we carry the remains, the remnants of those precious ancestors, the Denisovans, the Neanderthals and Anzick.  Through their DNA, and ours, we reach back tens of thousands of years on the human migration path.  Their journey is also our journey.  It’s absolutely amazing and it’s no wonder people have so many questions and such a sense of enchantment.  But it’s true – and only you can determine exactly what this means to you.

Utilizing Ancient DNA at GedMatch

Mummy of 6 month old boy found in Greenland

It has been a wonderful week for those of us following ancient DNA full genome sequencing, because now we can compare our own results to those of the ancient people found whose DNA has been fully sequenced, including one Native American.

Felix Chandrakumar has uploaded the autosomal files of five ancient DNA specimens that have been fully sequenced to GedMatch.  Thanks Felix.

When news of these sequences first hit the academic presses, I was wishing for a way to compare our genomes – and now my wish has come true.

Utilizing GedMatch’s compare one to all function, I ran all of the sequences individually and found, surprisingly, that there are, in some cases, matches to contemporary people today.  I dropped the cM measure to 1 for both autosomal and X.

Please note that because these are ancient DNA sequences, they will all have some segments missing and none can be expected to be entirely complete.  Still, these sequences are far better than nothing.

1.  Montana Anzick at GedMatch

This is the only clearly Native American sample.

9-27-2014 – Please note that kit F999912 has been replaced by kit F999913.

10-23-2014 – Please note that kit F999913 has been replaced by kit F999919.

No matches at 1cM in the compare to all.  This must be because the SNP count is still at default thresholds, in light of information discovered later in this article.

Update – as it turns out, this kit was not finished processing when I did the one to one compare.  After it finished, the results were vastly different.  See this article for results.

2.  Paleo Eskimo from Greenland at GedMatch

http://www.y-str.org/2013/12/palaeo-eskimo-2000-bc-dna.html

F999906

Thirty-nine matches with segments as large at 3.8.  One group of matches appears to be a family.  One of these matches is my cousin’s wife.  That should lead to some interesting conversation around the table this holiday season!  All of these matches, except 1, are on the X chromosome.  This must be a function of these segments being passed intact for many generations.

I wrote about some unusual properties of X chromosomal inheritance and this seems to confirm that tendency in the X chromosome, or the matching thresholds are different at GedMatch for the X.

5.  Denisova at GedMatch

http://www.y-str.org/2013/08/denisova-dna.html

F999903

Two matches, one to yet another ancient entry and one to a contemporary individual on the X chromosome.

But now, for the fun part.

My Comparison

Before I start this section, I want to take a moment to remind everyone just how old these ancient segments are.

  • Anzick – about 12,500 years old
  • Paleo-Eskimo – about 4,000 years old
  • Altai Neanderthal – about 50,000 years old
  • Russian Caucasus Neanderthal – about 29,000 years old
  • Denisova – about 30,000 years old

In essence, the only way for these segments to survive intact to today would have been for them to enter the population of certain groups, as a whole, to be present in all of the members of that group, so that segment would no longer be divided and would be passed intact for many generation, until that group interbred with another group who did not carry that segment.  This is exactly what we see in endogamous populations today, such as the Askenazi Jewish population who is believed, based on their common shared DNA, to have descended from about 350 ancestors about 700 years ago.  Their descendants today number in the millions.

So, let’s see what we find.

I compared by own kit at GedMatch utilizing the one to one comparison feature, beginning with 500 SNPs and 1cM, dropping the SNP values to 400, then 300, then 200, until I obtained a match of some sort, if I obtained a match at all.

Typically in genetic genealogy, we’re looking for genealogy matches, so the default matching thresholds are set relatively high.  In this case, I’m looking for deep ancestral connections, if they exist, so I was intentionally forcing the thresholds low.  I’m particularly interested in the Anzick comparison, in light of my Native American and First Nations heritage.

The definition of IBS, identical by state, vs IBD, identical by descent segments varies by who is talking and in what context, but in essence, IBD means that there is a genealogy connection in the past several generations.

IBS means that the genealogy connection cannot be found and the IBS match can be a function of coming from a common population at some time in the past, or it can be a match by convergence, meaning that your DNA just happened to mutate to the same state as someone else’s.  If this is the case, then you wouldn’t expect to see multiple segments matching the same person and you would expect the matching segments to be quite short.  The chances of hundreds of SNPs just happening to align becomes increasingly unlikely the longer the matching SNP run.

So, having said that, here are my match results.

In my case, I’m particularly fortunate, because my mother tested her DNA as well.  By process of elimination, I can figure out which of my matches are through her, and then by inference, which are through my father or are truly IBS by convergence.

I carry Native heritage on both sides, but my mother’s is proven to specific Native ancestors where my father’s is only proven to certain lines and not yet confirmed through genealogy records to specific ancestors.

Because I had so many matches, quite to my surprise, I also compared my mother’s DNA to the Anzick sample, combined the two results and put them in a common spreadsheet, shown below.  White are my matches.  Pink are Mom’s matches, and the green markers are on the segments where we both match the Anzick sample, confirming that my match is indeed through mother.

My mother matches 2 segments at 100 SNPs but neither match is the same as my segment.

Matching to Ancestral Lines

I’ve been mapping my DNA to specific ancestors utilizing the genealogy information of matches and triangulation for some time.  This consists of finding common ancestors with your matches.  Finding one person who matches you and maps to a common ancestor on a particular segment consists of a hint.  Finding two that share the same ancestral line and match you and each other on the same segment is confirmation – hence, the three of you triangulate.  More than three is extra gravy:)

I have also recorded other relevant information in my matches file, like the GedMatch Native chromosomal comparisons when I wrote “The Autosomal Me” series about hunting for my Native chromosomal segments.

So, after looking at the information above, it occurred to me that I should add this ancestral match information to my matches spreadsheet, just for fun, if nothing else.

I added these matches, noted the source as GedMatch and then sorted the results, anxious to see what we might find.  Would at least one of these segments fall into the proven Native segments or the matches to people who also descend from those lines?

What I found was both astonishing and confusing….and true to form to genealogy, introduced new questions.

I have extracted relevant matching groups from my spreadsheet and will discuss them and why they are relevant.  You can click on any of the images to see a larger image.

ancient compare3

This first set of matches is intensely interesting, and equally as confusing.

First, these matches are to both me and mother, so they are confirmed through my mother’s lines.  In case anyone notices, yes, I did switch my mother’s line color to white and mine to pink to be consistent with my master match spreadsheet coloration.

Second, both mother and I match the Anzick line on the matches I’ve utilized as examples.

Third, both 23andMe and Dr. Doug McDonald confirmed the segments in red as Native which includes the entire Anzick segment.

Fourth, utilizing the Gedmatch admixture tools, mother and I had this range in common.  I described this technique in “The Autosomal Me” series.

Fifth, these segments show up for two distinct genealogy lines that do not intersect until my grandparents, the Johann Michael Miller line AND the Acadian Lore line.

Sixth, the Acadian Lore line is the line with proven Native ancestors.

Seventh, the Miller line has no Native ancestors and only one opportunity for a Native ancestor, which is the unknown wife of Philip Jacob Miller who married about 1750 to a women rumored to be Magdalena Rochette, but research shows absolutely no source for that information, nor any Rochette family anyplace in any proximity in the same or surrounding counties to the Miller family.  The Miller’s were Brethren.  Furthermore, there is no oral history of a Native ancestor in this line, but there have been other hints along the way, such as the matching segments of some of the “cousins” who show as Native as well.

Eighth, this makes my head hurt, because this looks, for all the world, like Philip Jacob Miller who was living in Bedford County, PA when he married about 1750 may have married someone related to the Acadian lines who had intermarried with the Micmac.  While this is certainly possible, it’s not a possibility I would ever have suspected.

Let’s see what else the matches show.

ancient compare4

In this matching segment Mom and I both match Emma, who descends from Marie, a MicMac woman.  Mom’s Anzik match is part of this same segment.

ancient compare5

In this matching segment, Mom and I both match cousin Denny who descends from the Lore line who is Acadian and confirmed to have MicMac ancestry.  Mom’s Anzik segments all fit in this range as well.

ancient compare6

In this matching segment, cousin Herbie’s match to Mom and I falls inside the Anzick segments of both Mom and I.

ancient compare7

More matching to the proven Miller line.

ancient compare8

This last grouping with Mom is equally as confusing at the first.  Mom and I both match cousin Denny on the Lore side, proven Acadian.

Mom and I both match the Miller side too, and the Anzik for both of us falls dead center in these matches.

There are more, several more matches, that also indicate these same families, but I’m not including them because they don’t add anything not shown in these examples.  Interestingly enough, there are no pointers to other families, so this isn’t something random.  Furthermore, on my father’s side, as frustrating as it is, here are no Anzick matches that correlate with proven family lines.  ARGGHHHHHH……

On matches that I don’t share with mother, there is one of particular interest.

ancient compare9

You’ll notice that the Anzik and the Paleo-Greenland samples match each other, as well as me.  This is my match, and by inference, not through mother.  Unfortunately, the other people in this match group don’t know their ancestors or we can’t identify a common ancestor.

Given the genetic genealogy gold standard of checking to see if your autosomal matches match each other, I went back to GedMatch to see if the Paleo-Greenland kit matched the Clovis Anzik kit on this segment, and indeed, they do, plus many more segments as well.  So, at some time, in some place, the ancestors of these two people separated by thousands of miles were related to each other.  Their common ancestor would have either been in Asia or in the Northern part of Canada if the Paleo people from Greenland entered from that direction.

Regardless, it’s interesting, very interesting.

What Have I Learned?

Always do experiments.  You never know what you’ll find.

I’m much more closely related to the Anzick individual than I am to the others. This isn’t surprising given my Native heritage along with the endogamous culture of the Acadians.

My relationship level to these ancient people is as follows:

Lived Years Ago Relatedness Comments
Montana Anzick 12,500 107.4cM at 200 SNP level Confirmed to Lore (Acadian) and Miller, but not other lines
Greenland Paleo 4,000 2.3cM at 200 SNP level No family line matches, does match to Anzick in one location
Altai Neanderthal 50,000 2.1cM at 200 SNP level No family line matches
Russian Neanderthal 29,000 0
Denisovan 30,000 1.2cM at 200 SNP No family line matches

The Lores and the Millers

Looking further at the Lore and Miller lines, there are only two options for how these matching segments could have occurred.  There are too many for them all to be convergence, so we’ll have to assume that they are indeed because we shared a common population at some time and place.

The nature of how small the segments are testify that this is not a relatively recent common ancestor, but how “unrecent” is open to debate.  Given that Neanderthal and Denisovan ancient segments are found in all Europeans today, it’s certainly possible for these segments to be passed intact, even after thousands of years.

The confirmations to the Lore line come through proven Lore cousins and also through other proven Acadian non-specific matches.  This means that the Acadian population is highly endogamous and when I find an Acadian match, it often means that I’m related through many ancestors many times.  This, of course, increases the opportunity for the DNA to be passed forward, and decreases the opportunity for it to be lost in transmission, but it also complicates the genealogy greatly and makes determining which ancestor the DNA segment came from almost impossible.

However, I think we are safe to say the segments are from the Acadian population, although my assumption would be that they are from the Native Ancestors and not the French, given the high number of Anzick matches, Anzick being proven to be Native.  Having said that, that assumption may not be entirely correct.

The Miller line is relatively well documented and entirely from Germany/Switzerland, immigrating in the early 1700s, with the exception of the one unknown wife in the first generation married in the US.  Further examination would have to be done to discover if any of the matches came through Johann Michael Miller’s sons other than Philip Jacob Miller, my ancestor.  There are only three confirmed children, all sons.  If this segment shows up in Johann Michael Miller’s line not associated with son Philip Jacob Miller, then we would confirm that indeed the segment came from Europe and not a previously unknown Native or mixed wife of Philip Jacob.

Bottom Line

So, what’s the bottom line here?  I know far more than I did.  The information confirms, yet again, the Acadian Native lines, but it introduces difficult questions about the Miller line.  I have even more tantalizing questions for which I have no answers today, but I tell you what, I wouldn’t trade this journey along the genetic pathway with all of its unexpected bumps, rocks, slippery slopes and crevices for anything!!  That’s why it’s called an adventure!

Finding Native American Ethnic Results in Germanic People

I’m often asked about the significance of small percentages of autosomal DNA in results.  Specifically, the small percentages are often of Native American or results that would suggest Native admixture.  One of the first questions I always ask is whether or not the individual has Germanic or eastern European admixture.

Why?

Take a look at this map of the Invasion of the Roman Empire.  See the Huns and their path?

Hun map

It’s no wonder we’re so admixed.

Here’s a map of the Hunnic empire at its peak under Attila between the years 420-469.

Hun emplire

But that wasn’t the end of the Asian invasions.  The Magyars, who settled in Hungary arrived from Asia as well, in the 800s and 900s, as shown on this map from LaSalle University.

magyar map

Since both the Hungarians and some Germanic people descend from Asian populations, as do Native Americans, albeit thousands of years apart, it’s not unrealistic to expect that, as populations, they share a genetic connection.

Therefore, when people who carry heritage from this region of the world show small amounts of Native or Asian origin, I’m not surprised.  However, for Americans, trying to sort out their Native ethnic heritage, this is most unhelpful.

Let’s take a look at the perfect example candidate.  This man is exactly half Hungarian and half German.  Let’s see what his DNA results say, relative to any Asian or Native heritage, utilizing the testing companies and the free admixture tools at www.gedmatch.com.

He has not tested at Ancestry, but at Family Tree DNA, his myOrigins report 96% European, 4% Middle Eastern.  At 23andMe in speculative view, he shows 99.7 European and .2 sub-saharan African.

Moving to the admixture tools at GedMatch, MDLP is not recommended for Asian or Native ancestry, so I have excluded that tool.

Eurogenes K13 is the most recently updated admixture tool, so let’s take a look at that one first.

Eurogenes K13

 JK Eurogenes K13 v2

Eurogenes K13 showed 7% West Asian, which makes perfect sense considering his heritage, but it might be counted as “Native” in other circumstances, although I would certainly be very skeptical about counting it as such.

However, East Asian, Siberian and Amerindian would all be amalgamated into the Native American category, for a combined percentage of 1.31.

jk eurogenes k13 chart

However, selecting the “admixture proportions by chromosome” view shows something a bit different.  The cumulative percentages, by chromosome equate to 10.10%.  Some researchers mistakenly add this amount and use that as their percentage of Native ancestry.  This is not the case, because those are the portions of 100% of each individual chromosome, and the total would need to be divided by 22 to obtain the average value across all chromosomes.  The total is irrelevant, and the average may not reflect how the developer determines the amount of admixture because chromosomes are not the same size nor carry the same number of SNPs.  Questions relative to the functional underpinnings of each tool should be addressed to the developers.

Dodecad

I understand that there is a newer version of Dodecad, but that it has not been submitted to GedMatch for inclusion, per a discussion with GedMatch.  I can’t tell which of the Dodecad versions on GedMatch is the most current, so I ran the results utilizing both v3 and 12b.

jk dodecad v3

jk dodecad v3 chart

I hope v3 is not the most current, because it does not include any Native American category or pseudocategory – although there is a smattering of Northeast Asian at .27% and Southwest Asian at 1%.

Dodecad 12b below

jk dodecad 12b

The 12b version does show .52% Siberian and 2.6% Southwest Asian, although I’m not at all sure the Southwest Asian should be included.

HarappaWorld

jk harappaworld

jk harappaworld chart

Harappaworld shows .09 Siberian, .27% American (Native American), .23% Beringian and 1.8% Southwest Asian, although I would not include Southwest Asian in the Native calculation.

In Summary

Neither Family Tree DNA nor 23andMe find Native ancestry in our German/Hungarian tester, but all 3 of the admixture tools at Gedmatch find either small amounts of Native or Asian ancestry that could certainly be interpreted as Native, such as Siberian or Beringian.

Does this mean this German/Hungarian man has Native American ancestry?  Of course not, but it does probably mean that the Native population and his ancestral populations did share some genes from the same gene pool thousands of years ago.

While you might think this is improbable, or impossible, consider for a minute that every person outside of Africa today carries some percentage of Neanderthal DNA, and all Europeans also carry Denisovan DNA.  Our DNA does indeed have staying power over the millennia, especially once an entire population or group of people is involved.  We’ve recently seen this same type of scenarios in the full genome sequencing of a 24,000 year old Siberian male skeleton.

Our German/Hungarian man carries 2.4% Neanderthal DNA according to 23andMe and 2.7% according to the Genographic Project, which also reports that he carries 3.9% Denisovan.  The European average is about 2% for Neanderthal.

The net-net of this is that minority admixture is not always what it seems to be, especially when utilizing autosomal DNA to detect small amounts of Native American admixture.  The big picture needs to be taken into consideration.  Caution is advised.

When searching for Native admixture, when possible, both Y DNA and mitochondrial DNA give specific answers for specific pedigree lines relative to ancestry.  Of course, to utilize Y or mtDNA, the tester must descend from the Native ancestor either directly paternally to test the male Y chromosome, or directly matrilineally to test the mitochondrial line.  You can read about this type of testing, and how it works, in my article, Proving Native American Ancestry Using DNA.  You can also read about other ways to prove Native ancestry using autosomal DNA, including how to unravel which pedigree line the Native ancestry descends from, utilizing admixture tools, in the article, “The Autosomal Me.”

John Campbell (c1772-1838) of Little Sycamore Creek – 52 Ancestors #20

John Campbell’s early life is shrouded in the mists of time.  We can’t positively identify him until he’s an adult, living in Claiborne County, Tennessee, beginning in 1802.  By that time, he would have been roughly 30 years old, married, and probably had 2 or 3 children by his wife, Jane “Jenny” Dobkins, daughter of Jacob Dobkins and Dorcas Johnson.

The closest thing to proof we have that Jane was a Dobkins is Claiborne County lawyer and historian, P.G. Fulkerson (born in 1840) who interviewed old-timers and documented the early families.  He stated that Jacob’s daughter, Jane, married John Campbell and his other daughter Elizabeth married George Campbell. Jacob Dobkins died in 1833, and the Claiborne County courthouse burned in 1838, so if Jacob had a will or estate settlement that named his children, it’s lost to flames.

We believe that John Campbell was born in Virginia based on census information from his children in 1880.

John’s children were:

  • Jacob Campbell born about 1810, died 1879/1880, Collin Co., TX, married Temperance Rice
  • Elizabeth born about 1802, dead before 1842, married Lazarus Dodson
  • Elmira born about 1804 married John Pearson
  • Jane born about 1807, married a Freeman, then a Cloud
  • Martha born 1807/1808, died after 1850, married Elisha Jones, moved to Coles County, Illinois before 1839
  • Rutha born about 1813, died after 1870, married Preston Holt
  • George Washington Campbell born about 1813, died after 1870, probably in Denton County, Texas, married Nancy Eastridge, then Mary unknown
  • William Newton Campbell born 1817, died 1908 Tillman Co. OK, married Sydnia Holt, shown in the photo below

???????????????????????????????

I spent years, decades actually, chasing the wrong parents for John Campbell.  I’ve chased so many parents for this man that I’ve just about ruled everyone out and the ones I haven’t ruled out HAVE to be his parents by process of elimination.  If only it were that easy.  Campbells are like rabbits – they have huge families, are found everyplace and they all have the same first names.  John – how could you be any more generic?  And the man we presume is his brother is named George.  Not much better.  Why not Hezekiah and Azariah???

Several years ago a cousin sent me part of her Campbell research, 4 pages of a 23 page document.  In the portion she sent, she states that back in the 1950s, some Campbell relatives were interviewed who were quite elderly, and they reported that John’s father had been James, as told by their grandparents.  That information morphed into the James Campbell from the northern part of Hawkins County who was also descended from the Crockett line.  This did make some sense, as John’s grandson’s middle name was Crockett, although his first name was David.  The problem is that when you track that James in Hawkins County, TN and his widow and children, there is no John and absolutely no hint of a connection with the John Campbell in Claiborne County, Tennessee, nor the George he is so closely associated with.  Not only that, but James Campbell lived in Carter’s Valley, no place near Jacob Dobkins whose daughters John and George Campbell both married.

In Hawkins County, there are two very distinctive groups of Campbell men.  The group that lived about 20 miles north of Rogersville in Carter’s Valley, who believed they were actually settling in Virginia originally, and Charles Campbell who lived just south of Rogersville across the Holston River on Dodson Creek.  The North group is who James Campbell descended from the Crockett family is associated with.  Charles Campbell, living on Dodson Creek, had 2 sons, John and George, and Jacob Dobkins, whose daughters John and George married, lived just up the road at Bulls Gap, about 9 miles or so.  Charles Campbell lived at the ford of the Holston River, so I’d wager that everyone who crossed the river stopped by to visit, probably including Jacob Dobkins and his daughters.

Charles Campbell was living on Dodson’s Creek in 1788 and possibly as early as 1783.  In 1793, he deeded land jointly to John and George Campbell, from Hawkins Co., for 45#, 150 acres on the south side of the Holston River on the west fork of Dodson Creek.  Charles signed the deed and John Payne was the witness.  The description was metes and bounds except for a stake at the mountain.

On Feb. 26, 1802, book 3-54, George and John Campbell of Hawkins Co. sell to Daniel Seyster the 149 acres on the fork of Dodson Creek where “John Campbell now lives” for 225#.  Both men signed and the witnesses are William Paine, Michael Roark and Charles Campbell. It was proved in the May session of the court in 1802 by Michael Roark, which implies that the Campbell men were gone by that time.

John Campbell is no longer found in Hawkins County.  On May 1, 1802, John first appears in Claiborne County when he purchases land from Alexander Outlaw.  This deed is in the loose papers in the front of deed book A.

Alexander Outlaw of Jefferson Co. TN to John Campbell of Claiborne, copied from Book A page 32 – May 1, 1802 – for $400 in hand and paid by John Campbell, tract of land on the North fork of Sycamore Creek adjoining a survey of 640 acres of James Cooper and Nathaniel Henderson beginning on a grassy hill on the North side of said Creek…300 acres.  Alexander signs.  Witness Jacob Dobbins and James A. Perreman.  Registered July 7 1802.

In the same court session, John Campbell is assigned with other men to “view and lay out a road from Fort Butler to Mulberry Gap and report to next court.”

In 1809, John purchases slaves on the same day, from the same person who sells slaves to Jacob Dobkins.  Note that this same male slave, or another by the same name, is sold within the family in 1839 after John Campbell’s death.

March 29, 1809 – Jesse Cheek of Grainger County to John Campbell, negro boy Charles for $300, signed and witnessed by Solomon and Reuben Dobkins. (note this same day Jesse Cheek and his daughter sold slaves to Jacob Dobkins as well).

1809 – Elizabeth Cheek of Grainger does sell and deliver a negro girl named Jamima aged six years unto John Campbell of Claiborne and by virtue and effect of these presents to bind myself and my heirs to warrant and defend said negro from all persons and claims…Elizabeth signs…March 24, 1809 witness Jesse Cheek Senior and Jr.

Followed directly by…

I, Jesse Cheek, hath bargained and sold unto Jacob Dobkins 4 negroes names Aneker or Anekey, Mitilty, Jiary, Amelyer for the consideration of $130 in hand paid.  March 29, 1809 Jesse signs, registered July 30, 1809.  John Campbell and Solomon Dobkins witness.

In 1811, John Campbell purchases more land.

Jan. 21, 1811 Abner Chapman of Warren Co., Georgia to John Campbell of Claiborne $100 the land where said John Campbell now lives at the head of the north fork of Sycamore Creek (metes and bounds)…original corner of Chapman grant for 400 acres….stake in Campbell’s line…Campbell’s corner…crossing line in Chapman grant…containing 300 acres more or less.  Signed.  Wit Walter Evans and Abel Lanham.  Registered May 18, 1811

For the next many years, John Campbell along with George Campbell and often Jacob Dobkins are assigned as jurors and to work on and lay out roads.  This is normal activity for the timeframe.  Courts, which were held quarterly, were quite the social event of the season – and everyone attended.  If they weren’t a juror, they certainly wanted to watch the proceedings.  It’s said that one time there was so much imbibing that court had to be adjourned because the justices fell off the bench.

It appears in 1812 that John managed to upset someone, although there were two John Campbells, the other being the son of Arthur Campbell of Middlesboro, KY, who lived just beyond the Cumberland Gap.  This Martin Beaty did sue numerous people in the Arthur Campbell family, so maybe our John didn’t get himself sued.

March 25, 1812 – pages 18 and 19 – Martin Beaty vs John Campbell, defendant appears in court by Jacob Peck and Charles F. Keith his attys for slander, appealed for unit of error – moved to next court.  (Note – Beatty lives where Kentucky Rd. crosses Gap Creek, very near Middlesboro, KY where Arthur Campbell lived.)

In 1817, John Campbell was security for Solomon Dobkins, who was a constable.

In 1823, John Campbell buys and sells some land.

1823, June 4 – William Willoughby of Sullivan Co and John Campbell of Claiborne $600 paid in hand tract of land beginning on Brumfield Ridley’s corner chestnut then down the Valley south…stake in the side of Powell’s mountain…200 acres…being the tract where John Condry and others now live.  William Signs.  Witness Hugh Graham and R. Rose.

1823 – John Campbell to Jacob Campbell for $300 land on both sides of main road from the spring fork of Sycamore Creek to Little Mulberry Creek being one half of a two hundred acre tract of land granted by the St of NC to Matthew Willoughby of number 79 dated Feb. 13, 1791 and said half begins at a chestnut tree at the beginning of said grant running with the grant line…crossing said road…stake in the side of Powell’s mountain in the grant line…containing 100 acres to Jacob Campbell.  John Campbell signs.  Witness Walter Evans (he is the clerk).  Registered Jan 15 1824.  Proved in open court May 1823.

John Campbell dies in 1838.  There remains some confusion about exactly where John died.  He had some connection to Coles County, Illinois, possibly only because his daughter lived there and the documents in question may only be referring to her residence in Coles County.  Some indication is that John died there, but in the subsequent deeds, it suggests that he died in Claiborne County.  Regardless, we know that he was dead on or before Sept 22, 1838 when William Hicks built John’s coffin and submitted a receipt for payment for $5.

In 1840, a William Hicks was living 2 doors away from a William and George Campbell, so I’m betting that John Campbell was buried in Claiborne County. William Hicks also purchased items at the estate sale of John Campbell in 1838.  If John was buried in Claiborne County, in September, I’m thinking that no one would want to transport a body from Illinois to Claiborne County for burial, by wagon, at about 20 miles a day.  Google maps says that it’s about 445 miles so that would equate to about 3 weeks.  By that time, I’m thinking they would be burying him along the road someplace or giving him a water burial in the Ohio River.

If John died in Claiborne County, which seems very likely, he could be buried in the old Jacob Dobkins Cemetery which seems to be the family cemetery, shown below, and has many early unmarked graves, including that of Jacob Dobkins and his wife.  There was not a cemetery on John Campbell’s land, unless there was an early cemetery where Liberty Church and cemetery stand today, which is certainly possible.

Dobkins cemetery

On the 1839 tax list, John is listed thus in the Rob Camp District in the far northeast part of the county:

  • John Campbell, decd – 443 acres worth $1300, 25 school acres worth $10, 2 slaves worth $900

Will Book A – page 71 – inventory of the estate of John Campbell, decd and of sales (3 pages) William Fugate and Jacob Campbell admin.

In the cousin’s research that she sent, she indicated that Henley Fugate was the uncle of John Campbell, and was married to Elizabeth Campbell, sister of John, although that would make Henley John’s brother-in-law, not his uncle.  Henley and Elizabeth’s son, William, according to the cousin, was administrator of John’s estate, along with Jacob Campbell, John’s son, and that somehow William Fugate and Jacob Campbell cheated the heirs out of their money.  There are 4 different court entries accounting for the funds, which don’t look in any way unusual, but there is always a back story to be found, it seems, especially having to do with estate settlements.  The Fugates do seem very connected to the Campbell family, so there may well be a family relationship there. The cousin also indicated that the families had lived adjacent in Virginia but since I can’t seem to find a location in Virginia, I have been unable to confirm that tidbit of data.

John Campbell’s sale was huge, as these things go, and as compared to other estates of the time.

  • Cash on hand after paying note – $649
  • Note from Johoel and William Fugate  – $15
  • Notes from others – $385.22

Apparently John was in the business of lending money as he was owed notes from several people.

John’s estate sale was Feb. 25, 1839.  We don’t know what the weather was like that day.  In Claiborne County, it could have been anything from snowing, slick and miserable to sunny and warm.  The administrators of John’s estate likely wanted to get things sold and felt early spring was a good time because farmers were likely to purchase things they needed for the upcoming planting season.

Sadly, the widow, Jane Campbell, had to purchase her own things at the estate sale, because all property was deemed to be that of the husband.  Therefore, Jane Campbell, widow, purchased the following items for a total of $87.63 and a half cents:

  • 1 saw
  • 1 little wheel
  • 1 set spools
  • 1 cupboard furniture
  • 1 reel bed and bedding

The total of the estate sale was $958.58

Was John a shoemaker or a blacksmith?  Was his slave trained to one of these professions?

What else does this tell us about John’s life?  He was obviously a farmer, but everyone was.  He had several horses; 2 mares, 2 colts, 3 horses and 4 yearlings.  He had a “lot of hogs,” which of course means a group that was sold together, and he also had almost 1000 pounds of bacon.  Fall was slaughtering time, so there were quite a few hogs that had been killed and processed, probably in a smoke house.  There was one ewe and lamb and obviously Jane felt fondly towards them.  There was also a “lot of sheep.”  There were 3 cows and a bull and there were 2 yoke of oxen.  Oxen were matched and trained to work together, so they were often sold together as well.

They also had bee gums, which were gum trees that bees lived in.  So in essence, he was an early beekeeper.  This means, of course, that they also had honey, which might be connected to the item called “big sugar.”

They had 3 beds, 3 trunks, 2 cupboards, a bureau and a clock, which was a luxury. John was not a poor farmer.  In fact, few people in Claiborne County had slaves, so John having 2 was rather unusual.  Those who did have slaves had 1 or 2 and a very few people had 10 or more.  In the 1830 census, John had 2 slaves and his father-in-law, Jacob Dobkins, had 4.  Finding this heritage of slavery within the family saddens my heart, although I realize that it was socially acceptable, even desirable, at the time.  Well, desirable by everyone except the slave.  Slaves on small farms were often well treated and had good lives, and I hope that is how these people were treated.

John’s children and their spouses also attended his estate sale except for his daughter, Martha, who lived in Illinois.  It’ must have been a sad day to see your parents things being divided like so much excess and being sold away from your mother.  Jane did, of course, retain her dower right to one third of his estate, but that didn’t stop the estate sale.

In July of 1839, the court record shows each of the children of John Campbell and what they received during their lifetimes.

July 22, 1839 – Estate of John Campbell, amounts received during this lifetime:

  • Jacob Campbell $210
  • George Campbell (blank)
  • Lazarus Dodson 192.95
  • Preston and Ruth Holt 170.00
  • Jane Freeman 43.50
  • Jefferson and Elmire? (Eliza?) Pearson 124.50
  • William Campbell 214.00
  • Martha Jones 65.75 of Illinois

Page 206 – settlement estate of John Campbell by William Fugate and Jacob Campbell before Wiley Huffaker, clerk of court – paid William Hicks for coffin- Sept 22, 1838 – $5.00  Paid Jane Campbell for her dower June 25, 1839

By 1839, John’s heirs are selling his land to their sibling, along with a slave described as a boy in this document, so not the same person purchased in 1809.

July 29, 1839 – Elisha Jones and Martha Jones his wife, formerly Martha Campbell and daughter of John Campbell, now decd of Coale Co., Illinois, to William and George Campbell of Claiborne Co., for $187.50 assign all right and interest of 1/8th share in consequence of Martha being a daughter and heir of the said John Cambell in tract of land containing 345 acres adjacent the lands of William McVay and Marcurioius Cook it being the tract of land where on the John Campbell formerly lived and whereon the said John Campbell died seized and possessed of subject to the dower of the widow and all right and title after the death of the widow.  Elisha signs and Martha with an X.  Witness William Niel and Jacob Campbell.

This is the entry that caused the confusion about where John died.  We know that Martha Campbell lived in Illinois, and given the other information we do have, I believe this is mean to convey that Martha Jones is of “Coale Co., Illinois” and not John Campbell.  The words “formerly lived” is always used after death.  John was clearly still very invested in Claiborne County, judging from his significant estate.

The East Tennessean Newspaper on Saturday, March 7th, 1840 ran the following legal notice:

On the 13th day of Match next at the late residence of John Campbell, dec’d, upon Little Sycamore Creek in Claiborne County – offer at public sale to the highest bidder, three slaves, Charles, 51 or 52, Jenny, 38 years and Berry, 25 years.  William Fugate and Jacob Campbell administrators of John Campbell, decd.  February 8, 1840.

On March 30, 1840, John Campbell’s negroes were sold.

In April 1841, the court notes reflect that John’s estate was now worth $2897.64 and two thirds cents.

In July 1841, Wiley Huffaker was the guardian to the children of Elizabeth Campbell Dodson, deceased, and Lazarus Dodson.

Feb 1843 – Settlement of the estate of John Campbell by William Fugate and Jacob Campbell admin.  Amount given to each heir of John Campbell as received by them in the lifetime of said deceased.

  • Jacob Campbell $210.00
  • George Campbell 103.65
  • Lasarous (Lazarus) Dotson 192.75
  • Preston Holt 170.16 and a half cents
  • Jane Freeman 43.50
  • Elmire Pearson 124.50
  • William Campbell 214.00
  • Martha Jones 65.75

This is a great list, as it shows that John Campbell loaned or gave his children part of their inheritance early.

Jacob Campbell, George Campbell, Jane Freeman, Jefferson Pearson, Preston Holt and Jane Campbell sell to William Campbell for $33.03 and 1/3 cents negro boy Charles which John Campbell died seized and possessed and Jefferson Pearson and Preston Holt having interest in said negro by their marriage with daughters of said John Campbell.  Signed except Jane who makes mark of a plus sign.  Witness Gray Garrett and Hugh Dobkins and registered Jan. 13, 1840.

In October 1843, a final settlement was made with the children of Elizabeth Campbell Dodson which lists her children, by name.

On Jan. 24, 1852, William Campbell sells to Daniel Jones of the same for $1300 the land where Daniel Jones now lives including the residence of John Campbell decd lying on Little Sycamore Creek including part of 2 grants, one to Alexander Outlaw and the other to Abner Chapman, beginning….southwest corner of Outlaw grant…closing line of Chapman grant…conditional corner between William Campbell and Daniel Jones…Outlaw grant.  Signed.  Registered March 10, 1852.  Witness Tennessee Cook and William Fugate.

This last deed clearly identifies which John Campbell we are talking about.  I brought these deeds forward in time, hoping to find a landmark of some sort that I could locate today. I was very lucky.  Skipping several transactions, I found this:

1903 – Jane Ann Jones et all to G.R. Sulfridge – deed of trust – all the old Daniel Jones home farm and tract deeded to Ann Jane Jones except that previously deeded to H. Friar and others, beginning at Sycamore Creek at Nancy Coles, Nancy Cooks line, across ridge to John Cunningham’s line, Buis corner, top of ridge, George Runions, Friar’s line, public road in Little Sycamore Valley, except the grave yard plot of 3/4 acre deeded to Liberty Church, 140 acres.

liberty cemetery sign

The Liberty Church!  I knew exactly where that was located.  Here’s a photo of some of the old settlers and the Old Liberty Church taken about 1902.  The church itself was founded in 1856 and the building in this photo was built in 1883, so this church did not exist when John Campbell was alive, but the fact that the cemetery was deeded to the church helped us locate John’s land.

liberty church

The Liberty church sits down on Little Sycamore road, but the cemetery sits up on a ridge beside the church and directly behind John Campbell’s house.

From this vantage point, you look down over the valley.  It’s quite beautiful!  John Campbell might be buried here.

Liberty cemetery

This photo, below, is John’s house from in the cemetery.

Campbell house from cemetery

It’s very likely that when John died, William Hicks made his casket, someone preached his funeral, and John was carried up the hill, probably in his wagon by his own team of oxen, and he was buried right here, forever standing silent sentry, looking over his land from what is called Little Ridge.

Here’s the house from the road.  My cousin, Daryl and I went to visit.  Once we discovered the landmark of Liberty Church, we couldn’t NOT visit.

Campbell house

The cemetery stands above the house on top of the ridge.

This was a prime piece of real estate, because it had a natural spring which still flows today.  The head of the spring is under the rocks and you can see that it has hollowed out a bed downstream.

Campbell spring

You can see the stream here, located in front of the house, where it’s not far to carry fresh water to the house.

Campbell spring 2

Campbell property

The current owners were very gracious allowing us to photograph the property and answering many questions.

campbell house 2

You can easily see the original house in the center.  The owners told us the center part is made of logs.

Campbell foundation

We asked about this odd part of the foundation and discovered that there is a hidden “room” under the house.  The owners told us that they had been told that it was for travelers from long ago so that they could stay someplace without disturbing the household if they arrived at night.  I wondered about the Civil War because this area was rife with marauding soldiers from both side and many families have stories about hiding from the soldiers.

Campbell step

The door into the original cabin and the original steps.  Most of the steps in this region are stones like this.  I have the stone from one of my ancestor’s cabins that is now my back step.  I’m not sure how I’d have gotten this one in my Jeep, but had it been offered, Daryl and I would have found a way, rest assured!

George and John Campbell, Brothers or Not?

One enduring mystery is the relationship of George Campbell and John Campbell.  If you believe Fulkerson, and there isn’t any reason not to, they married Dobkins sisters, but what he did not say was that they were brothers, although based on the joint deed from Charles Campbell, the timing and the enduring relationship between the Campbell men, it’s certainly a logical conclusion.  But is it accurate?

One fine day, when Daryl and I were researching on one of our many library trips, we stumbled on one right juicy lawsuit in which the divorce of one of John Campbell’s daughters is discussed.  It seems that one fall during “hog killing,” while married, she was “discovered” in a compromising position in the barn with her Campbell cousin, George’s son, who was named and identified as her cousin.  Woohooo…..our lucky day.  Until we realized that John’s daughter and George’s son would have been cousins through their mother’s as well.  If John and George were brothers then their children would have been double first cousins.  Thankfully, she apparently didn’t get pregnant from the encounter, just divorced.  I bet that was the talk of the neighborhood for a very long time.

These families didn’t live far apart.  It was closer over the mountains, and they had wagon trails and roads across the ridges that don’t exist today.

On the map below, the red arrow at left shows the approximate location of the land of George Campbell on Russell Creek.  The top arrow shows Jacob Dobkins land and the bottom arrow shows the circle drive today around the cemetery above John Campbell’s home.  These properties were about 3 miles from each other, John’s being “across the ridge” from the others.

Campbell map

I turned to DNA hoping that perhaps I could discover something more about the relationship between John and George Campbell.  Maybe, if I was lucky they would have a family mutation that linked them.  Maybe, today, they would match exactly to a family line out of Virginia.  When the descendants of both George and John were first Y DNA tested, several years ago, we certainly weren’t that lucky.

John’s descendant who tested is Jim Campbell and George’s descendant is Paul Campbell.

I would expect both Jim and Paul to match closely.  They do match, but not closely.

Both men are 5 generations from their oldest known ancestor, meaning John and George, so they would be 6 generations from a common ancestor if George and John are brothers.

At 67 markers they have 4 mutations difference.  This would be expected, at the 50th percentile, at about 8 generations, using the TIP tool at Family Tree DNA.  Of course, I’ve discussed this tool, its drawbacks and the fallacy of averages, but sometimes it’s the only tool you have and it’s certainly better than nothing.

At 37 markers Jim and Paul have 2 mutations, at 25 markers, they aren’t shown as a match, so that means 2 mutations (deduced because that is what they have at 37).  They are not showing as a match at 12 markers either, so more than 1 mutation difference in the first panel.

Moving to the Campbell DNA project, I can see the DNA results for the group that the administrator, Kevin Campbell has grouped both Jim and Paul into.  Fortunately, it is the same group, R1b-group 30.

Comparing their results with others in the group, we see that Jim (yellow 80569) has several mutations, and Paul (blue 81430) seems to match the modal value perfectly, so in essence has had no mutations since the common ancestor of this group.

Campbell group 30

Paul is the closest match to kit 23564 whose oldest ancestor is:

David J. Campbell, a son of Mark Washington Campbell and Mary Ann Campbell, was born on 26 August 1846 in Franklin County, PA.  It is speculated that he was born in Dry Run.  Also, according to speculation, his father, Mark W. Campbell, was born 15 December 1815 in the same county.  David married Marie Edna Gribble in 1870 and had six children. The family migrated to Clinton County, IA, McLean County, IL, Kearney County, NE, and Payette County, ID.

Jim’s closest match has 3 mutations, which isn’t terribly close, kit 28877 whose oldest ancestor is:

Solomon Campbell born Sept 1805, married Margaret Laurie, John N’s son James N Campbell Born Feb 2 1835.  Other children of John N are Martha, William, Margaret, Thomas L., James N., Solomon J., Jane.  It states on the 1841 Scottish census (Crofthead, Neilston, Renfrewshire) that John N and family were born in Ireland except for Jane who was born in Neilston.  Family also listed in Scotland 1851 census. Came to America in June of 1853, settled in Mason NH, John N. died 1878 Townsend Mass.

There is clearly no commonality in terms of either ancestors or location comparing the two closest matches.  Furthermore, Jim’s closest match is in Massachusetts when we know that John Campbell did arrive from Virginia, born in the 1770s, and was very likely part of the Scots/Irish migration from Pennsylvania through Virginia – simply given the historical patterns and logistics.

Let’s move to the individual markers and see what we can tell.

Campbell headingCampbell 389

I looked at the markers, and I think that DYS389(2) is having spontaneous mutations.  I say this because IF and assuming that truly, kit 81430 has not mutated, then all of the mutations in the 80569 kit happened after Charles Campbell who was born about 1750 or maybe slightly earlier.  It’s obvious from looking at oldest ancestors of the matches who have a value of 31 at DYS389(2) that  they could not all be descended from someone who lived since Charles Campbell.

Both Paul and Jim have taken the Family Finder autosomal test.  Let’s see what that says about their relationship.  I searched Jim’s account for matches having a surname of Campbell.  Sure enough, there were 5 results, but none of them were Paul.  These men should be 5th cousins if Charles Campbell is the father of both John and George.  That is a long way back and we would expect, on average for 5th cousins to carry only about 3cM of common DNA and less than 1%.  The FTDNA threshold is 7cM.

Jim’s sister has also taken the Family Finder test.  On the chance that she inherited differently, I checked to see if she perhaps matches Paul.  She does not.

We know that at Family Tree DNA matching threshold is set to approximately 7cM and that matches have to meet other criteria as well to be considered a match, like minimum SNPs and a minimum total cM as well.  Therefore, people with small amounts of matching DNA are not shown as matches at Family Tree DNA, but may share DNA that is important to find.  At GedMatch, you can set the matching thresholds yourself.

Let’s take a look at GedMatch to see if the John Campbell descendants match the George Campbell descendants.  Below, Jim and Paul’s autosomal DNA is compared for matches.

Campbell, paul vs jim

Sure enough, Jim and Paul match each other on four segments, one just above 3cM, just as predicted, and three more just over 1cM each.  Without a proven family connection, we would ignore segments of this size, but in a known family situation, these are important matching segments.

Let’s see if Jim’s sister matches Paul.

Campbell, paul vs jim sister

Yes, Jim’s sister and Jim both match Paul and in the same location on chromosome 7.

Do I match Paul?

Campbell, paul vs me

I do match Paul significantly.  On two chromosomes, the segments are 12 and 13 cm.  On chromosome 12, I match Paul on the same location at Jim’s sister.  On chromosome 13, I match on the same location as Jim matches Paul.

The GedMatch estimate is interesting in that it is 4.2 generations.  We know positively that we are a minimum of 7 generations distant, assuming that Charles is the father of both George and John.  Paul and I do not share any other ancestors.

Do I match Joy, the other George descendant?

Yes, I do, below.  Again, a minimum of 7 generations between us.

Campbell, me vs joy

Does Jim match Joy? No.

Does Joy match Jim’s sister? No.

Does Paul match Joy?  Both are descended from George.  Yes, on 10 different chromosomes.  These should be more closely matched than any John/George descendant matches, but they are further than 2.7 generations.

Campbell, paul vs joy

Do I match Jim, who is also descended from John Campbell?  Yes.

Campbell, me vs jim

Do I match Jim’s sister? Yes, on far more segments that I match Jim.

Campbell, me vs jim sister

The segments on chromosome 5 are identical between me, Jim and his sister.  Clearly, that came from John Campbell.  Our common ancestor, John Campbell is 5 generations from Jim and his sister, and 6 from me.

I created the following table of the results.  We have two descendants from George who match each other most closely.  Conversely, the descendants of John match each other more closely than the descendants of John match the descendants of George.  However, given the generational distance, the descendant of John and George do fall into the expected tolerance in the case of Paul matching Jim, John and me.

Jim (John) Jim’s sister Paul (George) Me (John) Joy (George)
Jim na siblings 1,3,7,13 5, 7, 11, 15 No
Jim’s sister siblings na 7, 10, 12, 13 2, 3, 5, 10, 11, 12, 13 No
Paul 1,3,7,13 7, 10, 12, 13 na 4, 9, 10, 12, 13 1, 2, 3, 5, 6, 7, 9, 12, 15, 16
Me 5, 7, 11, 15 2, 3, 5, 10, 11, 12, 13 4, 9, 10, 12, 13 na 16, 17
Joy No No 1, 2, 3, 5, 6, 7, 9, 12, 15, 16 16, 17 na

What else can we do now to further identify the parents of John and George Campbell, presuming that they are indeed brothers as the results above suggest?

At this point, there are three avenues open for study.

  1. Upgrade both Jim and Paul to 111 markers and hope for line marker mutations.
  2. Upgrade both Jim and Paul to the Big Y hoping for identical mutations, and if not, ones that will connect to another Campbell line. This option is very expensive at this time, and according to the Campbell surname administrator there are either few or no project members who have ordered the Big Y.
  3. Utilize Family Finder to search both Jim and Paul’s matches for consistent matches and hope for a clear genealogy clue as to where to begin the search for the common family of John and George.
  4. Add a dash of luck!

One thing is certain, whether John and George share a father or not, and whether that father is Charles Campbell who died before 1825 in Hawkins County, TN, or not, they do at some point not terribly distant past, share a common Campbell ancestor.  I surely wish there were any other proven children of Charles Campbell to test against.

As a matter of curiosity, I did check to see if any of the five of us Campbell descendants have matches to people with Fugate as an ancestral surname – and we all do.  However, many of these people also have Campbell ancestry and/or are from the Claiborne County region where we all have roots, so it would require more research to draw any inferences or conclusions on the Fugate question.

The Campbell lineage has been exceedingly frustrating. Why, oh why, didn’t they register that deed in 1825 in Hawkins County listing the heirs of Charles Campbell???

Family Tree DNA Releases myOrigins

my origins

On May 6th, Family Tree DNA released myOrigins as a free feature of their Family Finder autosomal DNA test.  This autosomal biogeographic feature was previously called Population Finder.  It has not just been renamed, but entirely reworked.

Currently, 22 population clusters in 7 major geographic groups are utilized to evaluate your biogeographic ethnicity or ancestry as compared to these groups, many of which are quite ancient.

my origins regions

Primary Population Clusters

  • Anatolia & Caucasus
  • Asian Northeast
  • Bering Expansion
  • East Africa Pastoralist
  • East Asian Coastal Islands
  • Eastern Afroasiatic
  • Eurasian Heartland
  • European Coastal Islands
  • European Coastal Plain
  • European Northlands
  • Indian Tectonic
  • Jewish Diaspora
  • Kalahari Basin
  • Niger-Congo Genesis
  • North African Coastlands
  • North Circumpolar
  • North Mediterranean
  • Trans-Ural Peneplain

Blended Population Clusters

  • Coastal Islands & Central Plain
  • Northlands & Coastal Plain
  • North Mediterranean & Coastal Plain
  • Trans-Euro Peneplain & Coastal Plain

Each of these groups has an explanation which can be found here.

Matching

Prior to release, Family Tree DNA sent out a notification about new matching options.  One of the new features is that you will be able to see the matching regions of the people you match – meaning your populations in common.  This powerful feature lets you see matches who are similar which can be extremely useful when searching for minority admixture, for example.  However, some participants don’t want their matches to be able to see their ethnicity, so everyone was given an ‘opt out’ option.  Fortunately, few people have opted out, less than 1%.

Be aware that only your primary matches are shown.  This means that your 4-5th cousins or more distant are not shown as ethnicity matches.

Here’s what the FTDNA notification said:

With myOrigins, you’ll be able compare your ethnicity with your Family Finder matches. If you want to share your ethnic origins with your matches, you don’t need to take any action.  You’ll automatically be able to compare your ethnicity with your matches when myOrigins becomes available.  This is the recommended option. However, we do understand that sharing your ethnicity with your matches is your choice so we’re sending you this reminder in case you want to not take part (opt-out). To opt-out, please follow the instructions below. *

  1. Click this link.
  2. If you are not logged in, do so.
  3. Select the “Do not share my ethnic breakdown with my matches. This will not let me compare my ethnicity with my matches.” radio button.
  4. Click the Save button.

You can get more details about what will be shared here.  You may also join our forums for discussion.  * You can change your privacy settings at any time. Thus, you may opt-out of or opt back into ethnic sharing at a later date if you change your mind.

What’s New?

Let’s take a look at the My Origins results.  You can see your results by clicking on “My Origins” on the Family Finder tab on your personal page at Family Tree DNA.

Ethnicity and Matches

Your population ethnicity is shown on the main page, as well as up to three shared regions that you share with your matches.  This means that if you share more than 3 regions with these people, the 4th one (or 5th or 6th, etc.) won’t show.  This also means that if your match has an ethnicity you don’t have, that won’t show either.

my origins ethnicity

Above, you see my main results page.  Please note that this map is what is known as a heat map.  This means that the darkest, or hottest, areas are where my highest percentages are found.

Each region has a breakdown that can be seen by clicking on the region bar.  My European region bar population cluster breakdown is shown below along with my ethnicity match to my mother.

my origins euro breakdown

And my Middle Eastern breakdown is shown below.

my origins middle east breakdown

Ethnicity Mapping

A great new feature is the mapping of the maternal and paternal ethnicity of your Family Finder matches, when known.  How does Family Tree DNA know?  The location data entered in the “Matches Map” location field.  Can’t remember if you completed these fields?  It’s easy to take a look and see.  On either the Y DNA or the mtDNA tabs, click on Matches Map and you’ll see your white balloon.  If the white balloon is in the location of your most distant ancestor in your paternal line (for Y) or your matrilineal line for mtDNA (your mother’s mother’s mother’s line on up the tree until you run out of mothers), then you’ve entered the location data and you’re good to go.  If your white balloon is on the equator, click on the tab at the bottom of the map that says “update ancestor’s location” and step through the questions.

ancestor location

If you haven’t completed this information, please do.  It makes the experience much more robust for everyone.

How Does This Tool Work?

my origins paternal matches

The buttons to the far right of the page show the mapped locations of the oldest paternal lines and the oldest matrilineal (mtDNA) lines of your matches.  Direct paternal matches would of course be surname matches, but only to their direct paternal lines. This does not take into account all of their “most distant ancestors,” just the direct paternal ones.  This is the yellow button.

The green button provides the direct maternal matches.

my origins maternal matches

Do not confuse this with your Matches Map for your own paternal (if you’re a male) or mitochondrial matches.  Just to illustrate the difference, here is my own direct maternal full sequence matches map, available on my mtDNA tab.  As you can see, they are very different and convey very different information for you.

my mito match map

Comparisons

By way of comparison, here are my mother’s myOrigins results.

my origins mother

Let’s say I want to see who else matches her from Germany where our most distant mitochondrial DNA ancestor is located.

I can expand the map by scrolling or using the + and – keys, and click on any of the balloons.

my origins individual match

Indeed, here is my balloon, right where it should be, and the 97% European match to my mother pops up right beside my balloon.  The matches are not broken down beyond region.

This is full screen, so just hit the back button or the link in the upper right hand corner that says “back to FTDNA” to return to your personal page.

Walk Through

Family Tree DNA has provided a walk-through of the new features.

Methodology

How did Family Tree DNA come up with these new regional and population cluster matches?

As we know, all of humanity came originally from Africa, and all of humanity that settled outside of Africa came through the Middle East.  People left the Middle East in groups, it would appear, and lived as isolated populations for some time in different parts of the world.  As they did, they developed mutations that are found only in that region, or are found much more frequently in that region as opposed to elsewhere.  Patterns of mutations like this are established, and when one of us matches those patterns, it’s determined that we have ancestry, either recent or perhaps ancient, from that region of the world.

The key to this puzzle is to find enough differentiation to be able to isolate or identify one group from another.  Of course, the groups eventually interbred, at least most of them did, which makes this even more challenging.

Family Tree DNA says in their paper describing the population clusters:

MyOrigins attempts to reduce the wild complexity of your genealogy to the major historical-genetic themes which arc through the life of our species since its emergence 100,000 years ago on the plains of Africa. Each of our 22 clusters describe a vivid and critical color on the palette from which history has drawn the brushstrokes which form the complexity that is your own genome. Though we are all different and distinct, we are also drawn from the same fundamental elements.

The explanatory narratives in myOrigins attempt to shed some detailed light upon each of the threads which we have highlighted in your genetic code. Though the discrete elements are common to all humans, the weight you give to each element is unique to you. Each individual therefore receives a narrative fabric tailored to their own personal history, a story stitched together from bits of DNA.

They have also provided a white paper about their methodology that provides more information.

After reading both of these documents, I much prefer the explanations provided for each cluster in the white paper over the shorter population cluster paper.  The longer version breaks the history down into relevant pieces and describes the earliest history and migrations of the various groups.

I was pleased to see the methodology that they used and that four different reference data bases were utilized.

  • GeneByGene DNA customer database
  • Human Genome Diversity Project
  • International HapMap Project
  • Estonian Biocentre

Given this wealth of resources, I was very surprised to see how few members of some references populations were utilized.

Population N Population N
Armenian 46 Lithuanian 6
Ashkenazi 60 Masai 140
British 39 Mbuti 15
Burmese 8 Moroccan 7
Cambodian 26 Mozabite 24
Danish 13 Norwegian 17
Filipino 20 Pashtun 33
Finnish 49 Polish 35
French 17 Portuguese 25
German 17 Russian 41
Gujarati 31 Saudi 19
Iraqi 12 Scottish 43
Irish 45 Slovakian 12
Italian 30 Spanish 124
Japanese 147 Surui 21
Karitiana 23 Swedish 33
Korean 15 Ukrainian 10
Kuwaiti 14 Yoruba 136

In particular, the areas of France, Germany, Norway, Slovakia, Denmark and the Ukraine appear to be very under-represented, especially given Family Tree DNA’s very heavy European-origin customer base .  I would hope that one of the priorities would be to expand this reference data base substantially.  Furthermore, I don’t see any New World references included here which calls into question Native American ancestry.

Webinar

Family Tree DNA typically provides a webinar for new products as well as general education.  The myOrigins webinar can be found in the archives at this link.  It can be viewed any time.  https://www.familytreedna.com/learn/ftdna/webinars/

Accuracy

How did they do?  Certainly, Family Tree DNA has a great new interface with wonderful new maps and comparison features.  Let’s take a look at accuracy and see if everything makes sense.

I am fortunate to have the DNA of one of my parents, my mother.  In the chart below, I’m comparing that result and inferring my father’s results by subtracting mine from my mother’s.  This may not be entirely accurate, because this presumes I received the full amount of that ethnicity from my mother, and that is probably not accurate – but – it’s the best I can do under the circumstances.  It’s safe to say that my father has a minimum of this amount of that particular population category and may have more.

Region Me Mom Dad Inferred Minimum
European Coastal Plain 68 17 51
European Northlands 12 7 5
Trans Ural Peneplain 11 10 1
European Coastal Islands 7 34 0
Anatolia and Caucus 3 0 3
North Mediterranean 0 34 0
Circumpolar 0 1 0
Undetermined* 0 0 40

*The Undetermined category is not from Family Tree DNA, but is the percentage of my father not accounted for by inference.  This 40% is DNA that I did not inherit if it falls into a different category.

Based on these results alone, I have the following observations.

    1. I find it odd that my mother has 34% North Mediterranean and I have none. We have no known ancestry from this region.
    2. My mother does have one distant line of Turkish DNA via France. I have presumed that my Middle Eastern (now Anatolia and Caucus) was through that line, but these results suggest otherwise.
    3. My mother’s Circumpolar may be Native American. She does have proven Native lines (Micmac) through the Acadian families.
    4. These results have missed both my Native lines (through both parents) and my African admixture although both are small percentages.
    5. The European Coastal Plain is one of the groups that covers nearly all of Europe. Given that my mother is 3/4th Dutch/German, with the balance being Acadian, Native and English, one would expect her to have significantly more, especially given my high percentage.
    6. The European Coastal Island percentages are very different for me and my mother, with me carrying much less than my mother.  This is curious, because she is 3/4th German/Dutch with between 1/8th and 3/16th English while my father’s lines are heavily UK.  My father’s ancestry may well be reflected in European Coastal Plain which covers a great deal of territory.

What We Need to Remember

All of the biogeographic tools, from Family Tree DNA, 23andMe and Ancestry, are “estimates” and each of the tools from the three major vendors rend different results.  Each one is using different combinations of reference populations, so this really isn’t surprising.  Hopefully, as the various companies increase their population references and the size of their reference data bases, the results will increasingly mesh from company to company.  These results are only as good as the back end tools and the DNA that you randomly inherited from your ancestors.

Furthermore, we all carry far more similar DNA than different DNA, so it’s extremely difficult to make judgment calls based on ranges.  Europe, for example, is extremely admixed and the US is moreso.  The British Isles were a destination location for many groups over thousands of years.  Some of the DNA being picked up by these tests may indeed be very ancient and may cause us to wonder where it came from.  In future test versions, this may be more perfectly refined.

There is no way to gauge “ancient” DNA, like from the Middle East Diaspora, from more contemporary DNA, only a thousand years or so old, once it’s in very small segments.  In other words, it’s all very individual and personal and pretty much cast in warm jello.  We’ve come a long way, but we aren’t “there” yet.  However, without these tools and the vendors working to make them better, we’ll never get “there,” so keep that in mind.

While this makes great conversation today, and there is no question about accuracy in terms of majority ancestry/ethnicity, no one should make any sweeping conclusions based on this information.  This is not “cast in concrete” in the same way as Y DNA and mitochondrial haplogroups and STR markers.  Those are irrefutable – while biogeographical ethnicity remains a bit ethereal.

In summary, I would simply say that this tool can provide great hints and tips, especially the matching, which is unique, but it can’t disprove anything.  The absence of minority admixture, which is what so many people are hunting for, may be the result of the various data bases and the infancy of the science itself, and not the absence of admixture.

My recommendation would be to utilize all three biogeographic admixture products as well as the free tools in the Admixture category at GedMatch.  Look for consistency in results between the tools.  I discussed this methodology in “The Autosomal Me” series.

What Next?

I asked Dr. David Mittelman, Chief Scientific Officer, at Family Tree DNA about the reference populations.  He indicated that he agreed that some of their reference populations are small and they are actively working to increase them.  He also stated that it is important to note that Family Tree DNA prioritized accuracy over false positives so they definitely took a conservative approach.

2013’s Dynamic Dozen – Top Genetic Genealogy Happenings

dna 8 ball

Last year I wrote a column at the end of the year titled  “2012 Top 10 Genetic Genealogy Happenings.”  It’s amazing the changes in this industry in just one year.  It certainly makes me wonder what the landscape a year from now will look like.

I’ve done the same thing this year, except we have a dozen.  I couldn’t whittle it down to 10, partly because there has been so much more going on and so much change – or in the case of Ancestry, who is noteworthy because they had so little positive movement.

If I were to characterize this year of genetic genealogy, I would call it The Year of the SNP, because that applies to both Y DNA and autosomal.  Maybe I’d call it The Legal SNP, because it is also the year of law, court decisions, lawsuits and FDA intervention.  To say it has been interesting is like calling the Eiffel Tower an oversized coat hanger.

I’ll say one thing…it has kept those of us who work and play in this industry hopping busy!  I guarantee you, the words “I’m bored” have come out of the mouth of no one in this industry this past year.

I’ve put these events in what I consider to be relatively accurate order.  We could debate all day about whether the SNP Tsunami or the 23andMe mess is more important or relevant – and there would be lots of arguing points and counterpoints…see…I told you lawyers were involved….but in reality, we don’t know yet, and in the end….it doesn’t matter what order they are in on the list:)

Y Chromosome SNP Tsunami Begins

The SNP tsumani began as a ripple a few years ago with the introduction at Family Tree DNA of the Walk the Y program in 2007.  This was an intensively manual process of SNP discovery, but it was effective.

By the time that the Geno 2.0 chip was introduced in 2012, 12,000+ SNPs would be included on that chip, including many that were always presumed to be equivalent and not regularly tested.  However, the Nat Geo chip tested them and indeed, the Y tree became massively shuffled.  The resolution to this tree shuffling hasn’t yet come out in the wash.  Family Tree DNA can’t really update their Y tree until a publication comes out with the new tree defined.  That publication has been discussed and anticipated for some time now, but it has yet to materialize.  In the mean time, the volunteers who maintain the ISOGG tree are swamped, to say the least.

Another similar test is the Chromo2 introduced this year by Britain’s DNA which scans 15,000 SNPs, many of them S SNPs not on the tree nor academically published, adding to the difficulty of figuring out where they fit on the Y tree.  While there are some very happy campers with their Chromo2 results, there is also a great deal of sloppy science, reporting and interpretation of “facts” through this company.  Kind of like Jekyll and Hyde.  See the Sloppy Science section.

But Walk the Y, Chromo2 and Geno 2.0, are only the tip of the iceburg.  The new “full Y” sequencing tests brought into the marketspace quietly in early 2013 by Full Genomes and then with a bang by Family Tree DNA with the their Big Y in November promise to revolutionize what we know about the Y chromosome by discovering thousands of previously unknown SNPs.  This will in effect swamp the Y tree whose branches we thought were already pretty robust, with thousands and thousands of leaves.

In essence, the promise of the “fully” sequenced Y is that what we might term personal or family SNPs will make SNP testing as useful as STR testing and give us yet another genealogy tool with which to separate various lines of one genetic family and to ratchet down on the time that the most common recent ancestor lived.

23andMe Comes Unraveled

The story of 23andMe began as the consummate American dotcom fairy tale, but sadly, has deteriorated into a saga with all of the components of a soap opera.  A wealthy wife starts what could be viewed as an upscale hobby business, followed by a messy divorce and a mystery run-in with the powerful overlording evil-step-mother FDA.  One of the founders of 23andMe is/was married to the founder of Google, so funding, at least initially wasn’t an issue, giving 23andMe the opportunity to make an unprecedented contribution in the genetic, health care and genetic genealogy world.

Another way of looking at this is that 23andMe is the epitome of the American Dream business, a startup, with altruism and good health, both thrown in for good measure, well intentioned, but poorly managed.  And as customers, be it for health or genealogy or both, we all bought into the altruistic “feel good” culture of helping find cures for dread diseases, like Parkinson’s, Alzheimer’s and cancer by contributing our DNA and responding to surveys.

The genetic genealogy community’s love affair with 23andMe began in 2009 when 23andMe started focusing on genealogy reporting for their tests, meaning cousin matches.  We, as a community, suddenly woke up and started ordering these tests in droves.  A few months later, Family Tree DNA also began offering this type of testing as well.  The defining difference being that 23andMe’s primary focus has always been on health and medical information with Family Tree DNA focused on genetic genealogy.  To 23andMe, the genetic genealogy community was an afterthought and genetic genealogy was just another marketing avenue to obtain more people for their health research data base.  For us, that wasn’t necessarily a bad thing.

For awhile, this love affair went along swimmingly, but then, in 2012, 23andMe obtained a patent for Parkinson’s Disease.  That act caused a lot of people to begin to question the corporate focus of 23andMe in the larger quagmire of the ethics of patenting genes as a whole.  Judy Russell, the Legal Genealogist, discussed this here.  It’s difficult to defend 23andMe’s Parkinson’s patent while flaying alive Myriad for their BRCA patent.  Was 23andMe really as altruistic as they would have us believe?

Personally, this event made me very nervous, but I withheld judgment.  But clearly, that was not the purpose for which I thought my DNA, and others, was being used.

But then came the Designer Baby patent in 2013.  This made me decidedly uncomfortable.  Yes, I know, some people said this really can’t be done, today, while others said that it’s being done anyway in some aspects…but the fact that this has been the corporate focus of 23andMe with their research, using our data, bothered me a great deal.  I have absolutely no issue with using this information to assure or select for healthy offspring – but I have a personal issue with technology to enable parents who would select a “beauty child,” one with blonde hair and blue eyes and who has the correct muscles to be a star athlete, or cheerleader, or whatever their vision of their as-yet-unconceived “perfect” child would be.  And clearly, based on 23andMe’s own patent submission, that is the focus of their patent.

Upon the issuance of the patent, 23andMe then said they have no intention of using it.  They did not say they won’t sell it.  This also makes absolutely no business sense, to focus valuable corporate resources on something you have no intention of using?  So either they weren’t being truthful, they lack effective management or they’ve changed their mind, but didn’t state such.

What came next, in late 2013 certainly points towards a lack of responsible management.

23andMe had been working with the FDA for approval the health and medical aspect of their product (which they were already providing to consumers prior to the November 22nd cease and desist order) for several years.  The FDA wants assurances that what 23andMe is telling consumers is accurate.  Based on the letter issued to 23andMe on November 22nd, and subsequent commentary, it appears that both entities were jointly working towards that common goal…until earlier this year when 23andMe mysteriously “somehow forgot” about the FDA, the information they owed them, their submissions, etc.  They also forgot their phone number and their e-mail addresses apparently as well, because the FDA said they had heard nothing from them in 6 months, which backdates to May of 2013.

It may be relevant that 23andMe added the executive position of President and filled it in June of 2013, and there was a lot of corporate housecleaning that went on at that time.  However, regardless of who got housecleaned, the responsibility for working with the FDA falls squarely on the shoulders of the founders, owners and executives of the company.  Period.  No excuses.  Something that critically important should be on the agenda of every executive management meeting.   Why?  In terms of corporate risk, this was obviously a very high risk item, perhaps the highest risk item, because the FDA can literally shut their doors and destroy them.  There is little they can do to control or affect the FDA situation, except to work with the FDA, meet deadlines and engender goodwill and a spirit of cooperation.  The risk of not doing that is exactly what happened.

It’s unknown at this time if 23andMe is really that corporately arrogant to think they could simply ignore the FDA, or blatantly corporately negligent or maybe simply corporately stupid, but they surely betrayed the trust and confidence of their customers by failing to meet their commitments with and to the FDA, or even communicate with them.  I mean, really, what were they thinking?

There has been an outpouring of sympathy for 23andme and negative backlash towards the FDA for their letter forcing 23andMe to stop selling their offending medical product, meaning the health portion of their testing.  However, in reality, the FDA was only meting out the consequences that 23andMe asked for.  My teenage kids knew this would happen.  If you do what you’re not supposed to….X, Y and Z will, or won’t, happen.  It’s called accountability.  Just ask my son about his prom….he remembers vividly.  Now why my kids, or 23andMe, would push an authority figure to that point, knowing full well the consequences, utterly mystifies me.  It did when my son was a teenager and it does with 23andMe as well.

Some people think that the FDA is trying to stand between consumers and their health information.  I don’t think so, at least not in this case.  Why I think that is because the FDA left the raw data files alone and they left the genetic genealogy aspect alone.  The FDA knows full well you can download your raw data and for $5 process it at a third party site, obtaining health related genetic information.  The difference is that Promethease is not interpreting any data for you, only providing information.

There is some good news in this and that is that from a genetic genealogy perspective, we seem to be safe, at least for now, from government interference with the testing that has been so productive for genetic genealogy.  The FDA had the perfect opportunity to squish us like a bug (thanks to the opening provided by 23andMe,) and they didn’t.

The really frustrating aspect of this is that 23andMe was a company who, with their deep pockets in Silicon Valley and other investors, could actually afford to wage a fight with the FDA, if need be.  The other companies who received the original 2010 FDA letter all went elsewhere and focused on something else.  But 23andMe didn’t, they decided to fight the fight, and we all supported their decision.  But they let us all down.  The fight they are fighting now is not the battle we anticipated, but one brought upon themselves by their own negligence.  This battle didn’t have to happen, and it may impair them financially to such a degree that if they need to fight the big fight, they won’t be able to.

Right now, 23andMe is selling their kits, but only as an ancestry product as they work through whatever process they are working through with the FDA.  Unfortunately, 23andMe is currently having some difficulties where the majority of matches are disappearing from some testers records.  In other cases, segments that previously matched are disappearing.  One would think, with their only revenue stream for now being the genetic genealogy marketspace that they would be wearing kid gloves and being extremely careful, but apparently not.  They might even consider making some of the changes and enhancements we’ve requested for so long that have fallen on deaf ears.

One thing is for sure, it will be extremely interesting to see where 23andMe is this time next year.  The soap opera continues.

I hope for the sake of all of the health consumers, both current and (potentially) future, that this dotcom fairy tale has a happy ending.

Supreme Court Decision – Genes Can’t Be Patented – Followed by Lawsuits

In a landmark decision, the Supreme Court determined that genes cannot be patented.  Myriad Genetics held patents on two BRCA genes that predisposed people to cancer.  The cost for the tests through Myriad was about $3000.  Six hours after the Supreme Court decision, Gene By Gene announced that same test for $995.  Other firms followed suit, and all were subsequently sued by Myriad for patent infringement.  I was shocked by this, but as one of my lawyer friends clearly pointed out, you can sue anyone for anything.  Making it stick is yet another matter.  Many firms settle to avoid long and very expensive legal battles.  Clearly, this issue is not yet resolved, although one would think a Supreme Court decision would be pretty definitive.  It potentially won’t be settled for a long time.

Gene By Gene Steps Up, Ramps Up and Produces

As 23andMe comes unraveled and Ancestry languishes in its mediocrity, Gene by Gene, the parent company of Family Tree DNA has stepped up to the plate, committed to do “whatever it takes,” ramped up the staff both through hiring and acquisitions, and is producing results.  This is, indeed, a breath of fresh air for genetic genealogists, as well as a welcome relief.

Autosomal DNA Comes of Age

Autosomal DNA testing and analysis has simply exploded this past year.  More and more people are testing, in part, because Ancestry.com has a captive audience in their subscription data base and more than a quarter million of those subscribers have purchased autosomal DNA tests.  That’s a good thing, in general, but there are some negative aspects relative to Ancestry, which are in the Ancestry section.

Another boon to autosomal testing was the 23andMe push to obtain a million records.  Of course, the operative word here is “was” but that may revive when the FDA issue is resolved.  One of the down sides to the 23andMe data base, aside from the fact that it’s not genealogist friendly, is that so many people, about 90%, don’t communicate.  They aren’t interested in genealogy.

A third factor is that Family Tree DNA has provided transfer ability for files from both 23andMe and Ancestry into their data base.

Fourth is the site, GedMatch, at www.gedmatch.com which provides additional matching and admixture tools and the ability to match below thresholds set by the testing companies.  This is sometimes critically important, especially when comparing to known cousins who just don’t happen to match at the higher thresholds, for example.  Unfortunately, not enough people know about GedMatch, or are willing to download their files.  Also unfortunate is that GedMatch has struggled for the past few months to keep up with the demand placed on their site and resources.

A great deal of time this year has been spent by those of us in the education aspect of genetic genealogy, in whatever our capacity, teaching about how to utilize autosomal results. It’s not necessarily straightforward.  For example, I wrote a 9 part series titled “The Autosomal Me” which detailed how to utilize chromosome mapping for finding minority ethnic admixture, which was, in my case, both Native and African American.

As the year ends, we have Family Tree DNA, 23andMe and Ancestry who offer the autosomal test which includes the relative-matching aspect.  Fortunately, we also have third party tools like www.GedMatch.com and www.DNAGedcom.com, without which we would be significantly hamstrung.  In the case of DNAGedcom, we would be unable to perform chromosome segment matching and triangulation with 23andMe data without Rob Warthen’s invaluable tool.

DNAGedcom – Indispensable Third Party Tool

While this tool, www.dnagedcom.com, falls into the Autosomal grouping, I have separated it out for individual mention because without this tool, the progress made this year in autosomal DNA ancestor and chromosomal mapping would have been impossible.  Family Tree DNA has always provided segment matching boundaries through their chromosome browser tool, but until recently, you could only download 5 matches at a time.  This is no longer the case, but for most of the year, Rob’s tool saved us massive amounts of time.

23andMe does not provide those chromosome boundaries, but utilizing Rob’s tool, you can obtain each of your matches in one download, and then you can obtain the list of who your matches match that is also on your match list by requesting each of those files separately.  Multiple steps?  Yes, but it’s the only way to obtain this information, and chromosome mapping without the segment data is impossible

A special hats off to Rob.  Please remember that Rob’s site is free, meaning it’s donation based.  So, please donate if you use the tool.

http://www.yourgeneticgenealogist.com/2013/01/brought-to-you-by-adoptiondna.html

I covered www.Gedmatch.com in the “Best of 2012” list, but they have struggled this year, beginning when Ancestry announced that raw data file downloads were available.  GedMatch consists of two individuals, volunteers, who are still struggling to keep up with the required processing and the tools.  They too are donation based, so don’t forget about them if you utilize their tools.

Ancestry – How Great Thou Aren’t

Ancestry is only on this list because of what they haven’t done.  When they initially introduced their autosomal product, they didn’t have any search capability, they didn’t have a chromosome browser and they didn’t have raw data file download capability, all of which their competitors had upon first release.  All they did have was a list of your matches, with their trees listed, with shakey leaves if you shared a common ancestor on your tree.  The implication, was, and is, of course, that if you have a DNA match and a shakey leaf, that IS your link, your genetic link, to each other.  Unfortunately, that is NOT the case, as CeCe Moore documented in her blog from Rootstech (starting just below the pictures) as an illustration of WHY we so desperately need a chromosome browser tool.

In a nutshell, Ancestry showed the wrong shakey leaf as the DNA connection – as proven by the fact that both of CeCe’s parents have tested at Ancestry and the shakey leaf person doesn’t match the requisite parent.  And there wasn’t just one, not two, but three instances of this.  What this means is, of course, that the DNA match and the shakey leaf match are entirely independent of each other.  In fact, you could have several common ancestors, but the DNA at any particular location comes only from one on either Mom or Dad’s side – any maybe not even the shakey leaf person.

So what Ancestry customers are receiving is a list of people they match and possible links, but most of them have no idea that this is the case, and blissfully believe they have found their genetic connection.  They have found a genealogical cousin, and it MIGHT be the genetic connection.  But then again, they could have found that cousin simply by searching for the same ancestor in Ancestry’s data base.  No DNA needed.

Ancestry has added a search feature, allowed raw data file downloads (thank you) and they have updated their ethnicity predictions.  The ethnicity predictions are certainly different, dramatically different, but equally as unrealistic.  See the Ethnicity Makeovers section for more on this.  The search function helps, but what we really need is the chromosome browser, which they have steadfastly avoided promising.  Instead, they have said that they will give us “something better,” but nothing has materialized.

I want to take this opportunity, to say, as loudly as possible, that TRUST ME IS NOT ACCEPTABLE in any way, shape or form when it comes to genetic matching.  I’m not sure what Ancestry has in mind by the way of “better,” but it if it’s anything like the mediocrity with which their existing DNA products have been rolled out, neither I nor any other serious genetic genealogist will be interested, satisfied or placated.

Regardless, it’s been nearly 2 years now.  Ancestry has the funds to do development.  They are not a small company.  This is obviously not a priority because they don’t need to develop this feature.  Why is this?  Because they can continue to sell tests and to give shakey leaves to customers, most of whom don’t understand the subtle “untruth” inherent in that leaf match – so are quite blissfully happy.

In years past, I worked in the computer industry when IBM was the Big Dog against whom everyone else competed.  I’m reminded of an old joke.  The IBM sales rep got married, and on his wedding night, he sat on the edge of the bed all night long regaling his bride in glorious detail with stories about just how good it was going to be….

You can sign a petition asking Ancestry to provide a chromosome browser here, and you can submit your request directly to Ancestry as well, although to date, this has not been effective.

The most frustrating aspect of this situation is that Ancestry, with their plethora of trees, savvy marketing and captive audience testers really was positioned to “do it right,” and hasn’t, at least not yet.  They seem to be more interested in selling kits and providing shakey leaves that are misleading in terms of what they mean than providing true tools.  One wonders if they are afraid that their customers will be “less happy” when they discover the truth and not developing a chromosome browser is a way to keep their customers blissfully in the dark.

Ancient DNA

This has been a huge year for advances in sequencing ancient DNA, something once thought unachievable.  We have learned a great deal, and there are many more skeletal remains just begging to be sequenced.  One absolutely fascinating find is that all people not African (and some who are African through backmigration) carry Neanderthal and Denisovan DNA.  Just this week, evidence of yet another archaic hominid line has been found in Neanderthal DNA and on Christmas Day, yet another article stating that type 2 Diabetes found in Native Americans has roots in their Neanderthal ancestors. Wow!

Closer to home, by several thousand years is the suggestion that haplogroup R did not exist in Europe after the ice age, and only later, replaced most of the population which, for males, appears to have been primarily haplogroup G.  It will be very interesting as the data bases of fully sequenced skeletons are built and compared.  The history of our ancestors is held in those precious bones.

Sloppy Science and Sensationalist Reporting

Unfortunately, as DNA becomes more mainstream, it becomes a target for both sloppy science or intentional misinterpretation, and possibly both.  Unfortunately, without academic publication, we can’t see results or have the sense of security that comes from the peer review process, so we don’t know if the science and conclusions stand up to muster.

The race to the buck in some instances is the catalyst for this. In other cases, and not in the links below, some people intentionally skew interpretations and results in order to either fulfill their own belief agenda or to sell “products and services” that invariably report specific findings.

It’s equally as unfortunate that much of these misconstrued and sensationalized results are coming from a testing company that goes by the names of BritainsDNA, ScotlandsDNA, IrelandsDNA and YorkshiresDNA. It certainly does nothing for their credibility in the eyes of people who are familiar with the topics at hand, but it does garner a lot of press and probably sells a lot of kits to the unwary.

I hope they publish their findings so we can remove the “sloppy science” aspect of this.  Sensationalist reporting, while irritating, can be dealt with if the science is sound.  However, until the results are published in a peer-reviewed academic journal, we have no way of knowing.

Thankfully, Debbie Kennett has been keeping her thumb on this situation, occurring primarily in the British Isles.

Citizen Science is Coming of Age

Citizen science has been slowing coming of age over the past few years.  By this, I mean when citizen scientists work as part of a team on a significant discovery or paper.  Bill Hurst comes to mind with his work with Dr. Doron Behar on his paper, A Copernican Reassessment of the Human Mitochondrial DNA from its Root or what know as the RSRS model.  As the years have progressed, more and more discoveries have been made or assisted by citizen scientists, sometimes through our projects and other times through individual research.  JOGG, the Journal of Genetic Genealogy, which is currently on hiatus waiting for Dr. Turi King, the new editor, to become available, was a great avenue for peer reviewed publication.  Recently, research projects have been set up by citizen scientists, sometimes crowd-funded, for specific areas of research.  This is a very new aspect to scientific research, and one not before utilized.

The first paper below includes the Family Tree DNA Lab, Thomas and Astrid Krahn, then with Family Tree DNA and Bonnie Schrack, genetic genealogist and citizen scientist, along with Dr. Michael Hammer from the University of Arizona and others.

Ethnicity Makeovers – Still Not Soup

Unfortunately, ethnicity percentages, as provided by the major testing companies still disappoint more than thrill, at least for those who have either tested at more than one lab or who pretty well know their ethnicity via an extensive pedigree chart.

Ancestry.com is by far the worse example, swinging like a pendulum from one extreme to the other.  But I have to hand it to them, their marketing is amazing.  When I signed in, about to discover that my results had literally almost reversed, I was greeted with the banner “a new you.”  Yea, a new me, based on Ancestry’s erroneous interpretation.  And by reversed, I’m serious.  I went from 80% British Isles to 6% and then from 0% Western Europe to 79%. So now, I have an old wrong one and a new wrong one – and indeed they are very different.  Of course, neither one is correct…..but those are just pesky details…

23andMe updated their ethnicity product this year as well, and fine tuned it yet another time.  My results at 23andMe are relatively accurate.  I saw very little change, but others saw more.  Some were pleased, some not.

The bottom line is that ethnicity tools are not well understood by consumers in terms of the timeframe that is being revealed, and it’s not consistent between vendors, nor are the results.  In some cases, they are flat out wrong, as with Ancestry, and can be proven.  This does not engender a great deal of confidence.  I only view these results as “interesting” or utilize them in very specific situations and then only using the individual admixture tools at www.Gedmatch.com on individual chromosome segments.

As Judy Russell says, “it’s not soup yet.”  That doesn’t mean it’s not interesting though, so long as you understand the difference between interesting and gospel.

Genetic Genealogy Education Goes Mainstream

With the explosion of genetic genealogy testing, as one might expect, the demand for education, and in particular, basic education has exploded as well.

I’ve written a 101 series, Kelly Wheaton wrote a series of lessons and CeCe Moore did as well.  Recently Family Tree DNA has also sponsored a series of free Webinars.  I know that at least one book is in process and very near publication, hopefully right after the first of the year.  We saw several conferences this year that provided a focus on Genetic Genealogy and I know several are planned for 2014.  Genetic genealogy is going mainstream!!!  Let’s hope that 2014 is equally as successful and that all these folks asking for training and education become avid genetic genealogists.

A Thank You in Closing

I want to close by taking a minute to thank the thousands of volunteers who make such a difference.  All of the project administrators at Family Tree DNA are volunteers, and according to their website, there are 7829 projects, all of which have at least one administrator, and many have multiple administrators.  In addition, everyone who answers questions on a list or board or on Facebook is a volunteer.  Many donate their time to coordinate events, groups, or moderate online facilities.  Many speak at events or for groups.  Many more write articles for publications from blogs to family newsletters.  Additionally, there are countless websites today that include DNA results…all created and run by volunteers, not the least of which is the ISOGG site with the invaluable ISOGG wiki.  Without our volunteer army, there would be no genetic genealogy community.  Thank you, one and all.

2013 has been a banner year, and 2014 holds a great deal of promise, even without any surprises.  And if there is one thing this industry is well known for….it’s surprises.  I can’t wait to see what 2014 has in store for us!!!  All I can say is hold on tight….

Cherokee Mother of John Red Bank Payne

John Red Bank Payne

There is nothing I love more than a happy ending.  Second to that perhaps is to know that my blog or work helped someone, and in particularly, helped someone document their Native heritage.  In doing so, this confirms and unveils one more of our elusive Native people in early records.

I recently received a lovely thank you note from Shawn Potter.  We had exchanged notes earlier, after I wrote “The Autosomal Me” series, about how to utilize small segments of Native American (and Asian) DNA to identify Native American lines and/or ancestors.  This technique is called Minority Admixture Mapping (MAP) and was set forth in detail in various articles in the series.

Shawn’s note said:  “I’ve been doing more work on this segment and others following your method since we exchanged notes.  I’m pretty sure I’ve found the source of this Native American DNA — an ancestor named John Red Bank Payne who lived in North Georgia in the late 18th and 19th centuries.  Many of his descendants believe on the basis of circumstantial evidence that his mother was Cherokee.  I’ve found 10 descendants from four separate lines that inherited matching Native American DNA, pointing to one of his parents as the source.”

Along with this note, Shawn attached a beautiful 65 page book he had written for his family members which did document the Native DNA, but in the context of his family history.  He included their family story, the tales, the genealogical research, the DNA evidence and finally, a chapter of relevant Cherokee history complete with maps of the area where his ancestors lived. It’s a beautiful example of how to present something like this for non-DNA people to understand.  In addition, it’s also a wonderful roadmap, a “how to” book for how to approach this subject from a DNA/historical/genealogical perspective.  As hard as it is for me to sometimes remember, DNA is just a tool to utilize in the bigger genealogy picture.

Shawn has been gracious enough to allow me to reprint some of his work here, so from this point on, I’ll be extracting from his document.  Furthermore, Elizabeth Shown Mills would be ecstatic, because Shawn has fully documented and sourced his document.  I am not including that information here, but I’m sure he would gladly share the document itself with any interested parties.  You can contact Shawn at shpxlcp@comcast.net.

From the book, “Cherokee Mother of John Red Bank Payne” by Shawn Potter and Lois Carol Potter:

Descendants of John Red Bank Payne describe his mother as Cherokee. Yet, until now, some have questioned the truth of this claim because genealogists have been unable to identify John’s mother in contemporary records. A recent discovery, however, reveals both John Red Bank Payne and his sister Nancy Payne inherited Native American DNA.

Considering information from contemporary records, clues from local tradition, John’s name itself, and now the revelation that John and his sister inherited Native American DNA, there seems to be sufficient evidence to say John Red Bank Payne’s mother truly was Cherokee. The following summary describes what we know about John, his family, and his Native American DNA.

John Red Bank Payne was born perhaps near present-day Canton, Cherokee County, Georgia, on January 24, 1754, married Ann Henslee in Caswell County, North Carolina, on March 5, 1779, and died in Carnesville, Franklin County, Georgia, on December 14, 1831.

John’s father, Thomas Payne, was born in Westmorland County, Virginia, about 1725, and owned property in Halifax and Pittsylvania counties, Virginia, as well as Wilkes County, North Carolina, and Franklin County, Georgia.  Several factors suggest Thomas travelled with his older brother, William, to North Georgia and beyond, engaging in the deerskin trade with the Cherokee Nation during the mid 1700s. Thomas Payne died probably in Franklin County, Georgia, after February 23, 1811.

Contemporary records reveal Thomas had four children (William, John, Nancy, and Abigail) by his first wife, and nine children (Thomas, Nathaniel, Moses, Champness, Shrewsbury, Zebediah, Poindexter, Ruth, and Cleveland) by his second wife Yanaka Ayers.  Thomas married Yanaka probably in Halifax County, Virginia, before September 20, 1760.

Local North Georgia tradition identifies the first wife of Thomas Payne as a Cherokee woman. Anna Belle Little Tabor, in History of Franklin County, Georgia, wrote that “Trader Payne” managed a trading post on Payne’s Creek, and “one of his descendants, an offspring of his Cherokee marriage, later married Moses Ayers whose descendants still live in the county.”

Descendants of John Red Bank Payne also cite his name Red Bank, recorded in his son’s family Bible, as evidence of his Cherokee heritage.  Before the American Revolution, British Americans rarely defied English legal prohibitions against giving a child more than one Christian name.  So, the very existence of John’s name Red Bank suggests non-English ethnicity. On the other hand, many people of mixed English-Cherokee heritage were known by their Cherokee name as well as their English first and last names during this period.

Furthermore, while the form of John’s middle name is unlike normal English names, Red Bank conforms perfectly to standard Cherokee names.  It also is interesting to note, Red Bank was the name of a Cherokee village located on the south side of Etowah River to the southwest of present-day Canton, Cherokee County, Georgia.

While some believe the above information from contemporary records and clues from local tradition, as well as John’s name Red Bank, constitute sufficient proof of John’s Cherokee heritage, recently discovered DNA evidence confirms at least one of John’s parents had Native American ancestry. Ten descendants of John Red Bank Payne and his sister Nancy Payne, representing four separate lineages, inherited six segments of Native American DNA on chromosomes 2, 3, 5, 8, 13, and 18 (see Figure 1 for the relationship between these descendants; Figures 2-7 for images of their shared Native American DNA; and http://dna-explained.com/2013/06/02/the-autosomal-me-summary-and-pdf-file/ for an explanation of this method of identifying Native American chromosomal segments).

Upon careful reflection, there seems sufficient reason to believe John Red Bank Payne’s mother truly was Cherokee.

Roberta’s note:  I have redacted the surnames of current testers.

Payne chart

Chromosome 2, Segment 154-161

In this segment, Bert P, Rosa P, Nataan S, Cynthia S, and Kendall S inherited matching Native American DNA described as Amerindian, Siberian, Southeast Asian, and Oceanian by the Eurogenes V2 K15 admixture tool, and as North Amerind, Mesoamerican, South America Amerind, Arctic Amerind, East Siberian, Paleo Siberian, Samoedic, and East South Asian by the Magnus Ducatus Lituaniae Project World22 admixture tool. Since their common ancestors were Thomas Payne and his wife, the source of this Native American DNA must be either Thomas Payne or his wife. See Figures 2a-2g.

Note: Since Native Americans and East Asians share common ancestors in the pre-historic past, their DNA is similar to each other in many respects. This similarity often causes admixture tools to interpret Native American DNA as various types of East Asian DNA. Therefore, the presence of multiple types of East Asian DNA together with Native American DNA tends to validate the presence of Native American DNA.

Roberta’s Summary:  Shawn continues to document the other chromosome matches in the same manner.  In total, he has 10 descendants of Thomas Payne and his wife, who it turns out, indeed was Cherokee, as proven by this exercise in combination with historical records.  These people descend through 2 different children.  Cynthia and Kendall descend through daughter Nancy Payne, and the rest of the descendants descend through different children of John Red Bank Payne.  All of the DNA segments that Shawn utilized in his report share Native/Asian segments in both of these family groups, the descendants of both Nancy and John Red Bank Payne.

Shawn’s success in this project hinged on two things.  First, being able to test multiple (in this case, two) descendants of the original couple.  Second, he tested several people and had the tenacity to pursue the existence of Native DNA segments utilizing the Minority Admixture Mapping (MAP) technique set forth in “The Autosomal Me” series.  It certainly paid off.  Shawn confirmed that the wife of Thomas Payne was, indeed Native, most likely Cherokee since he was a Cherokee trader, and that today’s descendants do indeed carry her heritage in their DNA.

Great job Shawn!!  Wouldn’t you love to be his family member and one of the recipients of these lovely books about your ancestor! Someone’s going to have a wonderful Christmas!

Determining Ethnicity Percentages

Recently, as a comment to one of my blog postings, someone asked how the testing companies can reach so far back in time and tell you about your ancestors.  Great question.

The tests that reliably reach the furthest back, of course, are the direct line Y-Line and mitochondrial DNA tests, but the commenter was really asking about the ethnicity predictions.  Those tests are known as BGA, or biogeographical ancestry tests, but most people just think of them or refer to them as the ethnicity tests.

Currently, Family Tree DNA, 23andMe and Ancestry.com all provide this function as a part of their autosomal product along with the Genographic 2.0 test.  In addition, third party tools available at www.gedmatch.com don’t provide testing, but allow you to expand what you can learn with their admixture tools if you upload your raw data files to their site.  I wrote about how to use these ethnicity tools in “The Autosomal Me” series.  I’ve also written about how accurate ethnicity predictions from testing companies are, or aren’t, here, here and here.

But today, I’d like to just briefly review the 3 steps in ethnicity prediction, and how those steps are accomplished.  It’s simple, really, in concept, but like everything else, the devil is in the details.devil

There are three fundamental steps.

  • Creation of the underlying population data base.
  • Individual DNA extraction.
  • Comparison to the underlying population data base.

Step 1:  Creation of the underlying population data base.

Don’t we wish this was as simple as it sounds.  It isn’t.  In fact, this step is the underpinnings of the accuracy of the ethnicity predictions.  The old GIGO (garbage in, garbage out) concept applies here.

How do researchers today obtain samples of what ancestral populations looked like, genetically?  Of course, the evident answer is through burials, but burials are not only few and far between, the DNA often does not amplify, or isn’t obtainable at all, and when it is, we really don’t have any way to know if we have a representative sample of the indigenous population (at that point in time) or a group of travelers passing through.  So, by and large, with few exceptions, ancient DNA isn’t a readily available option.

The second way to obtain this type of information is to sample current populations, preferably ones in isolated regions, not prone to in-movement, like small villages in mountain valleys, for example, that have been stable “forever.”  This is the approach the National Geographic Society takes and a good part of what the Genograpic Geno 2.0 project funding does.  Indigenous populations are in most cases our most reliable link to the past.  These resources, combined with what we know about population movement and history are very telling.  In fact, National Geographic included over 75,000 AIMs (Ancestrally Informative Markers) on the Geno 2.0 chip when it was released.

The third way to obtain this type of information is by inference.  Both Ancestry.com and 23andMe do some of this.  Ancestry released its V2 ethnicity updates this week, and as a part of that update, they included a white paper available to DNA participants.  In that paper, Ancestry discusses their process for utilizing contributed pedigree charts and states that, aside from immigrant locations, such as the United States and Canada, a common location for 4 grandparents is sufficient information to include that individuals DNA as “native” to that location.  Ancestry used 3000 samples in their new ethnicity predictions to cover 26 geographic locations.  That’s only 115 samples, on average, per location to represent all of that population.  That’s pretty slim pickins.  Their most highly represented area is Eastern Europe with 432 samples and the least represented is Mali with 16.  The regions they cover are shown below.

Survey Monkey, a widely utilized web survey company, in their FAQ about Survey Size For Accuracy provides guidelines for obtaining a representative sample.  Take a look.  No matter which calculations you use relative to acceptable Margin of Error and Confidence Level, Ancestry’s sample size is extremely light.

23andMe states in their FAQ that their ethnicity prediction, called Ancestry Composition covers 22 reference populations and that they utilize public reference datasets in addition to their clients’ with known ancestry.

23andMe asks geographic ancestry questions of their customers in the “where are you from” survey, then incorporates the results of individuals with all 4 grandparents from a particular country.  One of the ways they utilize this data is to show you where on your chromosomes you match people whose 4 grandparents are from the same country.  In their tutorial, they do caution that just because a grandparent was born in a particular location doesn’t necessarily mean that they were originally from that location.  This is particularly true in the past few generations, since the industrial revolution.  However, it may still be a useful tool, when taken with the requisite grain of salt.

23andme 4 grandparents

The third way of creating the underlying population data base is to utilize academically published information or information otherwise available.  For example, the Human Genome Diversity Project (HGDP) information which represents 1050 individuals from 52 world populations is available for scrutiny.  Ancestry, in their paper, states that they utilized the HGDP data in addition to their own customer database as well as the Sorenson data, which they recently purchased.

Academically published articles are available as well.  Family Tree DNA utilizes 52 different populations in their reference data base.  They utilize published academic papers and the specific list is provided in their FAQ.

As you can see, there are different approaches and tools.  Depending on which of these tools are utilized, the underlying data base may look dramatically different, and the information held in the underlying data base will assuredly affect the results.

Step 2:  Your Individual DNA Extraction

This is actually the easy part – where you send your swab or spit off to the lab and have it processed.  All three of the main players utilize chip technology today.  For example, 23andMe focuses on and therefore utilizes medical SNPs, where Family Tree DNA actively avoids anything that reports medical information, and does not utilize those SNPs.

In Ancestry’s white paper, they provide an excellent graphic of how, at the molecular level, your DNA begins to provide information about the geographic location of your ancestors.  At each DNA location, or address, you have two alleles, one from each parent.  These alleles can have one of 4 values, or nucleotides, at each location, represented by the abbreviations T, A, C and G, short for Thymine, Adenine, Cytosine and Guanine.  Based on their values, and how frequently those values are found in comparison populations, we begin to fine correlations in geography, which takes us to the next step.

ancestry allele snps

Step 3:  Comparison to Underlying Population Data Base

Now that we have the two individual components in our recipe for ethnicity, a population reference set and your DNA results, we need to combine them.

After DNA extraction, your individual results are compared to the underlying data base.  Of course, the accuracy will depend on the quality, diversity, coverage and quantity of the underlying data base, and it will also depend on how many markers are being utilized or compared.

For example, Family Tree DNA utilizes about 295,000 out of 710,000 autosomal SNPs tested for ethnicity prediction.  Ancestry’s V1 product utilized about 30,000, but that has increased now to about 300,000 in the 2.0 version.

When comparing your alleles to the underlying data set one by one, patterns emerge, and it’s the patterns that are important.  To begin with, T, A, C and G are not absent entirely in any population, so looking at the results, it then becomes a statistics game.  This means that, as Ancestry’s graphic, above, shows, it becomes a matter of relativity (pardon the pun), and a matter of percentages.

For example, if the A allele above is shown is high frequencies in Eastern Europe, but in lower frequencies elsewhere, that’s good data, but may not by itself be relevant.  However if an entire segment of locations, like a street of DNA addresses, are found in high percentages in Eastern Europe, then that begins to be a pattern.  If you have several streets in the city of You that are from Eastern Europe, then that suggests strongly that some of your ancestors were from that region.

To show this in more detailed format, I’m shifting to the third party tool, GedMatch and one of their admixture tools.  I utilized this when writing the series, “The Autosomal Me” and in Part 2, “The Ancestor’s Speak,” I showed this example segment of DNA.

On the graph below, which is my chromosome painting of one a small part of one of my chromosomes on the top, and my mother’s showing the exact same segment on the bottom, the various types of ethnicity are colored, or painted.

The grid shows location, or address, 120 on the chromosome and each tick mark is another number, so 121, 122, etc.   It’s numbered so we can keep track of where we are on the chromosome.

You can readily see that both of us have a primary ethnicity of North European, shown by the teal.  This means that for this entire segment, the results are that our alleles are found in the highest frequencies in that region.

Gedmatch me mom

However, notice the South Asian, East Asian, Caucus, and North Amerindian. The important part to notice here, other than I didn’t inherit much of that segment at 123-127 from her, except for a small part of East Asian, is that these minority ethnicities tend to nest together.  Of course, this makes sense if you think about it.  Native Americans would carry Asian DNA, because that is where their ancestors lived.  By the same token, so would Germans and Polish people, given the history of invasion by the Mongols. Well, now, that’s kind of a monkey-wrench isn’t it???

This illustrates why the results may sometimes be confusing as well as how difficult it is to “identify” an ethnicity.  Furthermore, small segments such as this are often “not reported” by the testing companies because they fall under the “noise” threshold of between about 5 and 7cM, depending on the company, unless there are a lot of them and together they add up to be substantial.

In Summary

In an ideal world, we would have one resource that combines all of these tools.  Of course, these companies are “for profit,” except for National Geographic, and they are not going to be sharing their resources anytime soon.

I think it’s clear that the underlying data bases need to be expanded substantially.  The reliability of utilizing contributed pedigrees as representative of a population indigenous to an area is also questionable, especially pedigrees that only reach back two generations.

All of these tools are still in their infancy.  Both Ancestry and Family Tree DNA’s ethnicity tools are labeled as Beta.  There is useful information to be gleaned, but don’t take the results too seriously.  Look at them more as establishing a pattern.  If you want to take a deeper dive by utilizing your raw data and downloading it to GedMatch, you can certainly do so. The Autosomal Me series shows you how.

Just keep in mind that with ethnicity predictions, with all of the vendors, as is particularly evident when comparing results from multiple vendors, “your mileage may vary.”  Now you know why!
