Just One Cousin

Recently, someone wrote to me and said that they thought the autosomal DNA matching between groups of family members was wonderful, but they have “just one first cousin” and feel left out.  So, I decided to see what could be done with just two cousins.  In this case, the two cousins are full siblings and both first cousins to my mother, Barbara.  This would be the same process whether there was one or two cousins, since the two are siblings. Utilizing two cousins who are siblings just gives me the advantage of additional matching and triangulation capabilities.

This does presume that both people involved are willing to share and do a bit of comparison work on their various DNA accounts.  In other words, you can’t do this by yourself without cooperation from your cousin.

Here’s the common ancestor of our testers.

Miller Ferverda chart

Barbara, Cheryl and Don took a Family Finder autosomal DNA test at Family Tree DNA.

The DNA shared by Barbara, Cheryl and Don is from their common ancestral couple, Hiram B. Ferverda and Evaline Louise Miller.

Some of that shared DNA will be Hiram’s Ferverda DNA and some will be Evaline’s Miller DNA.  The only way to differentiate between the Ferverda and Miller DNA is to test people who are only Ferverda or only Miller, descendants of people upstream of Hiram and Evaline, and if there are any common segments between the testers and those Ferverda or Miller individuals, you can then assign that DNA segment to that side of the family – Miller or Ferverda.

I’m using Barbara’s chromosome as the “match to” background, below.  Cheryl, in orange, and Don, in blue, are shown as matches to Barbara.  You can see that these three people share a lot of their grandparents DNA.  You can also see where Don and Cheryl didn’t inherit the same DNA from their father, in some instances, like on chromosome 1 below, where Cheryl (orange) matches Barbara on a much larger part of the chromosome than Don does (blue.)  But then look at chromosome 13 where Barbara and Don match on a huge segment and Cheryl, just a small portion.  Don and Cheryl inherited different DNA from their parents at these locations.

The three testers’ common DNA segments on chromosome 1 are shown in the table below.  I’ve colored Cheryl’s pink and her brother, Don’s, blue.  You can see that Barbara matches some segments with Don that Cheryl didn’t inherit from her parents.  All of the DNA Barbara matches with Cheryl on this chromosome is also matched, at least in part, in that location, with Don.  The chart below, matches the graphic above, for chromosome 1 and is the “view data in a table” option on the chromosome browser as well as the leftmost “download to excel” option.  The download to excel option at right downloads all of the matches for the individual, not just the ones currently showing in the chromosome browser.

Two cousins combined

When at least two known relatives have tested, we have something to compare against.  In this case, we have a total of 3 people, 2 siblings and a first cousin, before we start matching outside known family.  We don’t know which of their shared DNA comes from which ancestor, but we can now look for people who match Barbara and at least Cheryl OR Don which proves a common ancestor between the three individuals.  Matching Barbara, Cheryl AND Don would be even better.

The gold standard for DNA matching, called triangulation, that proves a particular segment to a specific ancestor is as follows.

  • All (at least 2) people match you on the same segment.
  • Those people also match each other on the same segment.
  • Meaning, at least three people with a known common ancestral line must match on the same segment.

The key word here is “on the same segment”.

The next thing to do is to find out which of Barbara’s, Cheryl’s and Don’s matches are “in common with” each other.  This means Barbara, Cheryl and Don all share a matching segment with these other people, but without additional analysis, we can’t determine whether they share a match on the same segment or not.

I ran Barbara “in common with” Cheryl and you can see that the first two people returned on that match list were me and Don because matches are listed in the order of the largest cM of shared data first.  The “in common with” tool is the blue crossed arrows, below.

Two cousins ICW

Next I ran Barbara in common with Don.

There were a total of 43 people in common with Cheryl and 49 with Don.

I downloaded the matching individuals (download link at the bottom right of the match page) and sorted them in a spreadsheet to see who matches whom. Here’s what the first part of my spreadsheet looks like (sorted in chromosome and segment order.)  I colorized the rows by cousin for easier visualization.

Two cousins match example

We have 92 total matching individuals in common with Barbara and Cheryl and then Barbara and Don.  A total of 19 people are listed as matching BOTH Cheryl and Don (for a total of 38 rows in the spreadsheet), so that means that there are 54 people who are in common with either Barbara and Cheryl or Barbara and Don, but not in common with all 3, Barbara AND Cheryl AND Don.  This illustrates how differently siblings inherit DNA from their parents and how it affects matches another generation later.

In Common With Matches To both Don and Cheryl To Cheryl only or Don only, but not both
Barbara 19 (38 rows of 92) 54

Clearly, the people who match all three individuals, Barbara, Cheryl and Don are likely the closest relatives.

So let’s focus on those closest matching people.  If you were utilizing only one cousin here, you would simply utilize every “in common with” match between two individuals and move forward.  Because I have siblings here, and because I don’t want to deal with 72 different people, I’m using the fact that they are siblings to focus my efforts on the most closely related matches – people who match Barbara AND both siblings.  You could also limit your focus by something like a common ancestral surname between all match members.

The next step is for each tester, meaning Barbara, Cheryl and Don, to compare each individual on the common match list to their DNA.  This means that Barbara, Cheryl and Don all three will compare to all 18 individuals.  We now have only 18 matching people, instead of 19, because I removed my own matches, since mine are a subset of Barbara’s.  Checking to see how each of our testers matches each common matching person is the only way to determine that there is a three (or 4) way triangulation that will confirm a common ancestor.

There are two ways to do this at Family Tree DNA.

1. You can, 5 matches at a time, compare in the chromosome browser, then download only the matching segments to a spreadsheet for those 5 individuals. This means 4 sets of matches for each of three people.

Two cousins browser download

2. You can download Barbara, Cheryl and Don’s entire segment match list and then eliminate the matches that aren’t relevant to the discussion – meaning everyone except the 18 common matches between the three people.

The download option for the entire segment match list for the person whose kit you are looking at is shown at the top of the chromosome browser, to the right.  Downloading the currently showing individuals matching segments is shown at the top of the chromosome browser, to the left.

Because we can only push 5 people at a time to the chromosome browser, in this case, it will be easier to simply download all of the matches for each of the three individuals and then put them into a common spreadsheet and sort by the names we determined match in common between all three cousins.

I downloaded all of the matches for Barbara, Cheryl and Don, colorized them and then sorted them in the spreadsheet by the name of who they matched.  I then searched for the names of the 18 individuals who matched Barbara, Cheryl and Don, and copy/pasted them into a separate spreadsheet.

I could then sort the 18 matching individuals results by chromosome and start and end location.

two cousin matches

Barbara’s DNA matches are white rows, Cheryl’s are pink and Don’s are blue.

The segments where Barbara, Don and Cheryl all match more than one other person on an overlapping area of their DNA segments are colorized green.  This means that 4 or more people match on that same identical segment, the three known cousins and at least one other person.

The segments where at least Barbara and either Don or Cheryl (but not both) match at least one other person are colorized yellow. This means that least three people match on that same segment.

Since the gold standard of triangulation is 3 individuals matching on the same segment, both the yellow and green segments contain matches that fall into this category and are triangulated.  All of those segments match at least two of the cousins, who match each other, plus in some cases, additional people too.

Let’s walk through one triangulation sequence.

In the green cluster, above, you can see that Barbara, Cheryl and Don all match Arthur on overlapping portions of the same segment.  The overlapping portion between all 3 individuals and Arthur runs from 49,854,186 to 53,551,492.  In addition, both Don and Cheryl match Tiffany on part of that same segment and Barbara matches Dean on part as well.  These segments aren’t exactly the same for any of the cousins, with different amounts of matching DNA as reflected in the different cM and SNP values.

So, who is triangulated based on just this one green cluster?  Barbara, Cheryl, Don and Arthur are triangulated to a common ancestor.  We know that common ancestor is either the common ancestor of Cheryl, Don and Barbara – Hiram Ferverda and Evaline Miller – or upstream of that couple.

Tiffany is triangulated to both Cheryl and Don, but since Cheryl and Don are siblings, that’s irrelevant at this point – meaning we can’t tell if that match is IBS by chance or real because there is no additional match – at least not in this cluster.

In total, there are 19 green clusters (triangulated to at least 4 people) and 12 yellow clusters (triangulated to at least 3 people.)

In other words, the DNA that came from Hiram Ferverda and Evaline Miller is present in these matching people as well.  The million dollar question, is, of course, which upstream ancestor did it come from?  We genealogists are never satisfied, are we?  Every answer just leads to more questions.

Before we begin looking at the DNA results and discussing what they mean, I want to share with you the family tree of Hiram Ferverda and Evaline Miller, because the DNA of the people who match Don, Cheryl and Barbara had to come from these people as well.  This chart shows 7 generations back from Barbara, Cheryl and Don.  The common ancestors of the people with whom they triangulate are likely to be within this timeframe.

two cousins fan chart

The colorized ancestors above are the ancestors who contributed the X chromosome to both John Ferverda, Barbara’s father and Roscoe Ferverda, Cheryl and Don’s father.

In my working example, below, I’m utilizing the matches on chromosome 14 because chromosome 14 includes examples of a couple of interesting features.

Two cousins chr 14

Let’s look at the first green grouping.  All three cousins match to SB and then Barbara matches also to Constance and William, our Lentz cousin on part of that overlapping segment as well.  This suggests that this grouping might come from the Lentz side of the Miller tree, although we’ll see something else in a minute that might give us pause to reflect.  So just hold that thought.  Regardless, it does tell us that these individuals do share a common ancestor and it’s on the Miller side, not the Ferverda side.

The second green grouping is larger and includes larger segments as well, which are more reliably used, although the smaller green cluster clearly meets and exceeds the triangulation requirement of 3 matching individuals on the same segment.

This larger green cluster is actually quite interesting, because there are a total of 4 individuals, Ellen, Arthur, Eric and Tiffany who are all triangulated on this same segment with Don, Cheryl and Barbara.  So, not only are they triangulated to Don, Cheryl and Barbara, but also to each other.  These 7 people all share a common ancestor.

The yellow grouping shows an area where Eric matches Barbara and Don plus Arthur as well, but not Cheryl.  We don’t know anything about Arthur or Eric’s genealogy, so we don’t know if this is Miller or Ferverda DNA, at least not yet.  We’ll learn more about Arthur and Eric in a minute, even without their genealogy!

There are a couple of other areas on other chromosomes that are of interest too.

On this cluster on chromosome 12, we find a known Miller cousin, Rex, 2nd cousin to Barbara, Cheryl and Don.  Because Rex also descends from the parents of Evaline Miller, we know that this segment shared with Rex has to be Miller DNA, not Ferverda DNA.

Two cousins chr 12

On this segment of chromosome 3, below, we see that Barbara, Cheryl and Don match Herbert, another known Miller cousin, plus Dee and Constance in much smaller amounts on the same segment.  This tells us that this segment is descended from our common ancestor with Herbert.

Two cousins chr 3

Barbara, Don and Cheryl’s common ancestor with Herbert is Daniel Miller and Elizabeth Ulrich (Ullery), which makes them third cousins once removed – except – Herbert got a second dose of Miller DNA because Daniel Miller’s son, Isaac, married his first cousin who was also a Miller and shared grandparents with him.  So Herbert, genetically, is closer than he would appear since he received the double dose of Miller DNA three generations upstream.

Gotta love these close knit families.  The Millers were Brethren.  These double doses of family DNA often carry forward by matching downstream when they might otherwise not be expected do so.  That’s the upside of these endogamous groups.  Now, here’s the downside.

Two cousins chr 7

See the segments with the words problem written to the right?  Do you recognize what the problem is?  You’ll notice that in the matching group we have BOTH cousin Herbert who is a Miller (and not a Lentz) and cousin William who is a Lentz (and not a Miller.)

This is a very common situation in endogamous communities.

To make matters worse, we are dealing with very small segments here, where we often see confusion.  However, let’s look at the possibilities.

We do have triangulation, so one of three things has happened here.

First, the Brethren are an endogamous population that intermarried nearly exclusively within their faith.  The Lentz and Miller families were both Brethren.

Here are our possibilities.

  1. Our Lentz cousin has some Miller in one of his lines. This is entirely possible since he has a “short” pedigree chart and his families are living in the same Brethren communities as the other Lentz and Miller families.
  2. Our Miller cousin has some Lentz in one of his lines. That is less likely, because his genealogy is pretty well fleshed out, although certainly possible because, once again, the families were living within close proximity and attending the same churches, etc.
  3. This segment is truly a population based segment and will be found in people descending from that same base population. If this is the case, we still received it from one of our ancestors who came from that population, but since the Lentz and Miller lines may have both carried this same segment, we can’t tell who it came from. In other words, their common ancestor is further back in time than the Lentz and Miller families found in the US.

This segment cannot be IBS by chance because it does triangulate with the three cousins, Barbara, Don and Cheryl.  The definition of IBS by chance shows us that chance segments would not phase (or match with) with a parent.  If Don, Cheryl and Barbara all three carry this matching segment, it’s because their fathers both received it from their grandparents who were the common ancestor of Don, Cheryl and Barbara.

Neither Cheryl, Don nor Barbara can phase directly to their parents, who are deceased, so in this case, matching against first cousins is the best substitute we have.  We know that common DNA between the first cousins had to come from their father’s, who were brothers.  This in essence virtually phases Barbara, Don and Cheryl to their father’s on these matching segments.  Not ideal, by any means, but even partial parental phasing is better than no phasing at all.

A third match, Dean, shows Miller in his family tree, but I could not connect his Miller line to the Johann Michael Miller ancestral line, from which our Miller line descends – so Dean is not a known cousin.  Sometimes a common surname, even if found in the same geographic location, is not proof that the DNA connection is through that line.  It’s easy to make that assumption, but it’s an assumption that is just waiting to bite you.  Don’t do it!

Because of our known, proven DNA and genealogy matches to Herbert, we can attribute all of the segments where Herbert triangulates with either Barbara and Cheryl or Barbara and Don as Miller for all people involved.  This means that this common DNA descends either from Daniel Miller and Elizabeth Ulrich or Daniel’s father Philip Jacob Miller and Magdalene, surname unknown.

Why have I listed two couples?  Because, remember, Herbert has a double dose of Miller DNA from cousins and we don’t know which segment Barbara inherited, one from Daniel/Elizabeth or one from Philip Jacob/Magdalene (or some of each.)  If the segment is from Daniel/Elizabeth, it could have come from either the Ulrich or Miller side.  If it came from Daniel, then it also came from his father and mother, Philip Jacob/Magdalena and could either be Miller or Magdalena’s unknown line.

Herbert triangulate

Because of our known, proven DNA and genealogy matches to Rex, we can attribute all of the segments where Rex triangulates with either Barbara and Cheryl or Barbara and Don as Miller for all people involved.  Their common ancestor is John David Miller and Margaret Lentz, so their shared DNA could be either Lentz or Miller and is likely some of each.

Rex triangulate

For segments where there is no triangulation, but Barbara matches either Herbert or Rex, I still note that segment as Miller on my spreadsheet, since they are proven cousins, but I just omit the triangulation note.

For Barbara, that’s a total of 51 segments of her DNA that we can now assign to a Miller ancestral couple.

Furthermore, every segment that Barbara matches with either Cheryl or Don is now confirmed to be from her father’s side of the family, not her mother’s.  While we don’t have Barbara’s parents available for testing, this is a pseudo way to phase your results to determine matches from one parents’ side of the family.  For Barbara, that’s a total of 91 segments, some of them quite large.  For example, roughly half of chromosome 13 matched with Don.

Just as a matter of interest, within those 91 segments that Barbara matches with either Don or Cheryl, a total of only 7 segments matched exactly between all 3 individuals in terms of start and end location, cMs and SNPs.  While you might expect a number of small segments to match exactly, these weren’t all small.  In fact, most weren’t small and some were quite large.

Exactly matching DNA segments between Barbara and Cheryl and Barbara and Don.

Chromosome Matching cM Matching SNPs
1 8.65 1189
1 7.01 1150
8 27.79 7279
10 20.78 5141
12 27.68 6046
14 2.11 700
14 49.47 9032

This means that these segments were not divided at all in a total of 5 DNA transmission events.

  • Hiram to John
  • Hiram to Roscoe
  • John to Barbara
  • Roscoe to Cheryl
  • Roscoe to Don

Additionally, I carry two of these exact segments as well, so those two segments survived 6 transmission events.

Clearly these segments are what we would term “sticky” because they certainly are not following the statistical average of dividing the DNA in half (by 50%) in each transmission event.

There is one more thing we can tell from matching.

Both Barbara and Cheryl match with SB on the X chromosome on the same segments.

Two cousins X

This is particularly interesting because of the special inheritance path of the X chromosome.  We know that SB must be related on Evaline Miller’s side of the family, because John and Roscoe Ferverda did not receive an X chromosome from their father.  So Barbara, Cheryl and Don have to have received it from Evaline.  Unfortunately, SB listed no genealogy on Family Tree DNA, but based on the X chromosome inheritance path, I can tell you that SB is either descended from John David Miller and Margaret Lentz, or from the Schaeffer, Lentz or Moselman lines colored pink or blue, below.

Two cousins X fan

At this point, I made a chart of how the matches grouped with each other on each of the green clusters.

Just one cousin chart

I intended to create a nice chart in Excel or Word, but with all of the various colors of ink involved, I didn’t think I could find enough color differentiation so we’ll just have to suffer with my hand-made chart.  There are subtle color differences here – a different color or marker type for each of the 19 green clusters.

What I did was to look at each of the green DNA spreadsheet groupings and create a colorized chart, by group, for each grouping.  So everyone in the first cluster had their X in the boxes of who they matches in the same color, say blue pen.  The second group, orange marker, and so forth.  That way I can see who was orange or yellow or blue and if those groups tend to cluster together.

Remember Arthur and Eric from above, whose genealogy we knew nothing about.  You can see, for example, that Arthur matches in various groups with lots of people, and most often, Tiffany.  Arthur and Eric also match in multiple groups that include each other and Rex, a known Miller descendant, so we can attribute both Arthur and Eric’s DNA matches to the Miller side of the tree.  Keep in mind, all of these people also match with Barbara, Cheryl and Don.

Tiffany clusters with Arthur and Sarah and Eric in multiple groups and with Constance, David, Ellen, Leland and Rex in at least one other cluster.  So another Miller side person.

On chromosome 14, Eric, Ellen, Arthur and Tiffany were all triangulated on the same segment with Don, Cheryl and Barbara, so we know those 7 individuals unquestionably share a common ancestor.

Let’s look at SB again, our X match.  Since SB’s X connection can’t come from the Miller side, given the X inheritance path, and SB also matches with our Lentz cousin, it’s likely that SB is related through the Lentz lines.

Normally, when doing this matching relationship chart, you tend to see two distinct groupings, a mother’s side and a father’s side.  In other words, there will be some groups that absolutely don’t overlap with the others.  That’s not the case here.

So, by now you might be wondering what happened to the Ferverda side of the family?  I was secretly hoping to find a closet Ferverda relative in this exercise, and I thought we might have, actually.  Notice that Harold has no clustering at all, but he clearly matches Barbara, Cheryl and Don – but doesn’t cluster with any other Miller or Lentz cousins.  Therefore, he could be from the Ferverda side of the family, but since he provided no genealogy information or surnames at Family Tree DNA, I can’t easily tell.

However, I am not entirely without recourse.  I checked Harold “in common with” Barbara and discovered that he matches both Rex, our Miller cousin and William, our Lentz cousin, so even though Harold did not triangulate with William and/or Rex on any segments with both Barbara and/or Cheryl/Don, those Miller/Lentz matches certainly suggest descent from this line.  I’ll be sending him an e-mail!

So, there are no Ferverda cousins represented in these matches.

I decided to check one more thing, now that I know that all of these matches are on the Miller side and that we have 3 known, proven genealogical cousins, Rex, Herbert and William.  I wanted to see how many of our individuals who match Barbara, Cheryl and Don also match one of the known cousins.  I selected Barbara as the base match kit to use, since we know they all matched Barbara, Cheryl and Don, and then I ran “in common with” for each one of them with Barbara, with the following results.  A few did match one of the Miller or Lentz cousins, but fewer than I expected.miller matches chart

*However, we had a surprise.  Dean matched another Miller male individual whose line is proven to descend through two children of Philip Jacob Miller and Magdalena, surname unknown.  Another first cousin marriage.  Another cousin discovered!

Furthermore, I noticed yet another individual, Doug, in Barbara’s match list and in common with 6 of the matches as well.  Looking at Doug’s pedigree chart, not only is he a Miller descendant, he also descends from two of the Miller wives lines too.  Another cousin confirmed!

But why no Ferverda matches?

Recent immigrants.

The Ferverda side of the family immediately jumps the pond to Holland, with Hiram himself being an immigrant as a young teen in the 1860s.  There are few Ferverda (Fervida, Ferwerda) descendants here in the US to test, and many are Brethren or Mennonite.  Few people in the Netherlands have participated in DNA testing.

The converse of that, Evaline Miller’s lines have all been in the US since the early/mid-1700s, so there are lots of descendants.  Oh, the difference about a hundred years and 5 or 6 generations makes in the number of descendants who might be available to test.  This situation, unfortunately, created a very lopsided chart without the division I’m used to seeing.  On the other hand, thank goodness Evaline’s line and Hiram’s line are very distinct!

At this point, if you’re doing this “one cousin” exercise, you’ll need to do a few things.

1.  Check each of the matching individuals to see if they have uploaded or created a pedigree chart at Family Tree DNA. If they do, their pedigree icon will be green, shown below. If so, click on the icon and search for every surname (and variant) associated with your known common lines with your cousin.

2.  Check to see if these people entered a list of surnames, even if they don’t have a pedigree chart. The surnames are listed in the furthest right column. If you have entered your surnames, any that match yours will be bolded. Beware of variant spellings.

two cousins pedigree and surnames

You can see above that I am the only one of the matches shown with a pedigree chart icon, shown in green, and the common surnames are bolded at right.

3.  If your matches don’t have a pedigree chart, write to them and tell them you have a common ancestor and give them a list of your ancestors in your direct line. Please, PLEASE include the name on the kit that you match. Many people manage multiple kits and will ignore requests with only partial information.

4.  If you have additional cousins to test, do so. I’m sure you can see how valuable additional cousins DNA would be.

5.  Be sure to check your matches by “ancestral surname” to be sure that you haven’t missed any cousins who have already tested. The ancestral surname search box can be seen above the “known relationship” heading in the graphic above.

6.  If you haven’t done so, enter your surnames under the “Manage Personal Information” tab under “My Account” at Family Tree DNA. Then click on the genealogy tab, then Surnames.

Two cousins genealogy settings

7.  From your main personal page, of course, you can upload your Gedcom file by clicking on “My Family Tree.”

8.  Run “in common with” for each of the common matches of your two cousins and look for common matching names between them.  Those matching “in common with” names serve as a hint as to shared ancestry.  Your answer may be hiding in your cousins’ trees!

Utilize all of these tools to help your search.

Summary

Not bad for thinking we couldn’t do anything with our DNA matches because we had “just one cousin” to work with, even though I cheated and used siblings.

What, exactly, did we manage to do?

  • I attributed 91 segments of Barbara’s DNA to her father’s side of the tree.
  • I filled in 51 segments of Barbara’s DNA to ancestral couples.
  • I found 5 confirmed genealogy/DNA cousins.
  • I found 16 people whose genealogy is unknown, but who triangulate with Barbara, Cheryl and Don.  We know for sure which side of the tree these people match on – all Millers.
  • I can tell the X match which lines they descend from, even if they don’t know.
  • I can do one more very cool thing.  Utilizing the Lazarus utility at GedMatch, I can now recreate at least a partial autosomal DNA file for both John and Roscoe Ferverda, the fathers of our testers.  Join me in a couple days and we’ll see how that works!

This same process works between any two people who know how they are related and their common ancestor.  It’s a great way to find cousins you didn’t know you had, or you didn’t know have DNA tested, and how they are related to you and each other.

Some people get very discouraged when even thinking about working with endogamous populations, or cousin marriages.  One of the reasons I used this particular example is that I wanted to illustrate that while these situations are challenging from time to time, they are far from hopeless – so don’t let that deter you.

In fact, of the 5 confirmed cousins discovered during this process, some in unexpected ways, at least 3 and possibly 4 are through multiple lines.  Some of these matches are probably thanks to endogamy.

Happy hunting!

2014 Top Genetic Genealogy Happenings – A Baker’s Dozen +1

It’s that time again, to look over the year that has just passed and take stock of what has happened in the genetic genealogy world.  I wrote a review in both 2012 and 2013 as well.  Looking back, these momentous happenings seem quite “old hat” now.  For example, both www.GedMatch.com and www.DNAGedcom.com, once new, have become indispensable tools that we take for granted.  Please keep in mind that both of these tools (as well as others in the Tools section, below) depend on contributions, although GedMatch now has a tier 1 subscription offering for $10 per month as well.

So what was the big news in 2014?

Beyond the Tipping Point

Genetic genealogy has gone over the tipping point.  Genetic genealogy is now, unquestionably, mainstream and lots of people are taking part.  From the best I can figure, there are now approaching or have surpassed three million tests or test records, although certainly some of those are duplicates.

  • 500,000+ at 23andMe
  • 700,000+ at Ancestry
  • 700,000+ at Genographic

The organizations above represent “one-test” companies.  Family Tree DNA provides various kinds of genetic genealogy tests to the community and they have over 380,000 individuals with more than 700,000 test records.

In addition to the above mentioned mainstream firms, there are other companies that provide niche testing, often in addition to Family Tree DNA Y results.

In addition, there is what I would refer to as a secondary market for testing as well which certainly attracts people who are not necessarily genetic genealogists but who happen across their corporate information and decide the test looks interesting.  There is no way of knowing how many of those tests exist.

Additionally, there is still the Sorenson data base with Y and mtDNA tests which reportedly exceeded their 100,000 goal.

Spencer Wells spoke about the “viral spread threshold” in his talk in Houston at the International Genetic Genealogy Conference in October and terms 2013 as the year of infection.  I would certainly agree.

Autosomal Now the New Normal

Another change in the landscape is that now, autosomal DNA has become the “normal” test.  The big attraction to autosomal testing is that anyone can play and you get lots of matches.  Earlier in the year, one of my cousins was very disappointed in her brother’s Y DNA test because he only had a few matches, and couldn’t understand why anyone would test the Y instead of autosomal where you get lots and lots of matches.  Of course, she didn’t understand the difference in the tests or the goals of the tests – but I think as more and more people enter the playground – percentagewise – fewer and fewer do understand the differences.

Case in point is that someone contacted me about DNA and genealogy.  I asked them which tests they had taken and where and their answer was “the regular one.”  With a little more probing, I discovered that they took Ancestry’s autosomal test and had no clue there were any other types of tests available, what they could tell him about his ancestors or genetic history or that there were other vendors and pools to swim in as well.

A few years ago, we not only had to explain about DNA tests, but why the Y and mtDNA is important.  Today, we’ve come full circle in a sense – because now we don’t have to explain about DNA testing for genealogy in general but we still have to explain about those “unknown” tests, the Y and mtDNA.  One person recently asked me, “oh, are those new?”

Ancient DNA

This year has seen many ancient DNA specimens analyzed and sequenced at the full genomic level.

The year began with a paper titled, “When Populations Collide” which revealed that contemporary Europeans carry between 1-4% of Neanderthal DNA most often associated with hair and skin color, or keratin.  Africans, on the other hand, carry none or very little Neanderthal DNA.

http://dna-explained.com/2014/01/30/neanderthal-genome-further-defined-in-contemporary-eurasians/

A month later, a monumental paper was published that detailed the results of sequencing a 12,500 Clovis child, subsequently named Anzick or referred to as the Anzick Clovis child, in Montana.  That child is closely related to Native American people of today.

In June, another paper emerged where the authors had analyzed 8000 year old bones from the Fertile Crescent that shed light on the Neolithic area before the expansion from the Fertile Crescent into Europe.  These would be the farmers that assimilated with or replaced the hunter-gatherers already living in Europe.

Svante Paabo is the scientist who first sequenced the Neanderthal genome.  Here is a neanderthal mangreat interview and speech.  This man is so interesting.  If you have not read his book, “Neanderthal Man, In Search of Lost Genomes,” I strongly recommend it.

In the fall, yet another paper was released that contained extremely interesting information about the peopling and migration of humans across Europe and Asia.  This was just before Michael Hammer’s presentation at the Family Tree DNA conference, so I covered the paper along with Michael’s information about European ancestral populations in one article.  The take away messages from this are two-fold.  First, there was a previously undefined “ghost population” called Ancient North Eurasian (ANE) that is found in the northern portion of Asia that contributed to both Asian populations, including those that would become the Native Americans and European populations as well.  Secondarily, the people we thought were in Europe early may not have been, based on the ancient DNA remains we have to date.  Of course, that may change when more ancient DNA is fully sequenced which seems to be happening at an ever-increasing rate.

Ancient DNA Available for Citizen Scientists

If I were to give a Citizen Scientist of the Year award, this year’s award would go unquestionably to Felix Chandrakumar for his work with the ancient genome files and making them accessible to the genetic genealogy world.  Felix obtained the full genome files from the scientists involved in full genome analysis of ancient remains, reduced the files to the SNPs utilized by the autosomal testing companies in the genetic genealogy community, and has made them available at GedMatch.

http://dna-explained.com/2014/09/22/utilizing-ancient-dna-at-gedmatch/

If this topic is of interest to you, I encourage you to visit his blog and read his many posts over the past several months.

https://plus.google.com/+FelixChandrakumar/posts

The availability of these ancient results set off a sea of comparisons.  Many people with Native heritage matched Anzick’s file at some level, and many who are heavily Native American, particularly from Central and South America where there is less admixture match Anzick at what would statistically be considered within a genealogical timeframe.  Clearly, this isn’t possible, but it does speak to how endogamous populations affect DNA, even across thousands of years.

http://dna-explained.com/2014/09/23/analyzing-the-native-american-clovis-anzick-ancient-results/

Because Anzick is matching so heavily with the Mexican, Central and South American populations, it gives us the opportunity to extract mitochondrial DNA haplogroups from the matches that either are or may be Native, if they have not been recorded before.

http://dna-explained.com/2014/09/23/analyzing-the-native-american-clovis-anzick-ancient-results/

Needless to say, the matches of these ancient kits with contemporary people has left many people questioning how to interpret the results.  The answer is that we don’t really know yet, but there is a lot of study as well as speculation occurring.  In the citizen science community, this is how forward progress is made…eventually.

A Siberian sample that also matches the Malta Child whose remains were analyzed in late 2013.

http://dna-explained.com/2014/11/12/kostenki14-a-new-ancient-siberian-dna-sample/

Felix has prepared a list of kits that he has processed, along with their GedMatch numbers and other relevant information, like gender, haplogroup(s), age and location of sample.

http://www.y-str.org/p/ancient-dna.html

Furthermore, in a collaborative effort with Family Tree DNA, Felix formed an Ancient DNA project and uploaded the ancient autosomal files.  This is the first time that consumers can match with Ancient kits within the vendor’s data bases.

https://www.familytreedna.com/public/Ancient_DNA

Recently, GedMatch added a composite Archaic DNA Match comparison tool where your kit number is compared against all of the ancient DNA kits available.  The output is a heat map showing which samples you match most closely.

Indeed, it has been a banner year for ancient DNA and making additional discoveries about DNA and our ancestors.  Thank you Felix.

Haplogroup Definition

That SNP tsunami that we discussed last year…well, it made landfall this year and it has been storming all year long…in a good way.  At least, ultimately, it will be a good thing.  If you asked the haplogroup administrators today about that, they would probably be too tired to answer – as they’ve been quite overwhelmed with results.

The Big Y testing has been fantastically successful.  This is not from a Family Tree DNA perspective, but from a genetic genealogy perspective.  Branches have been being added to and sawed off of the haplotree on a daily basis.  This forced the renaming of the haplogroups from the old traditional R1b1a2 to R-M269 in 2012.  While there was some whimpering then, it would be nothing like the outright wailing now that would be occurring as haplogroup named reached 20 or so digits.

Alice Fairhurst discussed the SNP tsunami at the DNA Conference in Houston in October and I’m sure that the pace hasn’t slowed any between now and then.  According to Alice, in early 2014, there were 4115 individual SNPs on the ISOGG Tree, and as of the conference, there were 14,238 SNPs, with the 2014 addition total at that time standing at 10,213.  That is over 1000 per month or about 35 per day, every day.

Yes, indeed, that is the definition of a tsunami.  Every one of those additions requires one of a number of volunteers, generally haplogroup project administrators to evaluate the various Big Y results, the SNPs and novel variants included, where they need to be inserted in the tree and if branches need to be rearranged.  In some cases, naming request for previously unknown SNPs also need to be submitted.  This is all done behind the scenes and it’s not trivial.

The project I’m closest to is the R1b L-21 project because my Estes males fall into that group.  We’ve tested several, and I’ll be writing an article as soon as the final test is back.

The tree has grown unbelievably in this past year just within the L21 group.  This project includes over 700 individuals who have taken the Big Y test and shared their results which has defined about 440 branches of the L21 tree.  Currently there are almost 800 kits available if you count the ones on order and the 20 or so from another vendor.

Here is the L21 tree in January of 2014

L21 Jan 2014 crop

Compare this with today’s tree, below.

L21 dec 2014

Michael Walsh, Richard Stevens, David Stedman need to be commended for their incredible work in the R-L21 project.  Other administrators are doing equivalent work in other haplogroup projects as well.  I big thank you to everyone.  We’d be lost without you!

One of the results of this onslaught of information is that there have been fewer and fewer academic papers about haplogroups in the past few years.  In essence, by the time a paper can make it through the peer review cycle and into publication, the data in the paper is often already outdated relative to the Y chromosome.  Recently a new paper was released about haplogroup C3*.  While the data is quite valid, the authors didn’t utilize the new SNP naming nomenclature.  Before writing about the topic, I had to translate into SNPese.  Fortunately, C3* has been relatively stable.

10th Annual International Conference on Genetic Genealogy

The Family Tree DNA International Conference on Genetic Genealogy for project administrators is always wonderful, but this year was special because it was the 10th annual.  And yes, it was my 10th year attending as well.  In all these years, I had never had a photo with both Max and Bennett.  Everyone is always so busy at the conferences.  Getting any 3 people, especially those two, in the same place at the same time takes something just short of a miracle.

roberta, max and bennett

Ten years ago, it was the first genetic genealogy conference ever held, and was the only place to obtain genetic genealogy education outside of the rootsweb genealogy DNA list, which is still in existence today.  Family Tree DNA always has a nice blend of sessions.  I always particularly appreciate the scientific sessions because those topics generally aren’t covered elsewhere.

I thank Family Tree DNA for sponsoring all 10 conferences and continuing the tradition.  It’s really an amazing feat when you consider that 15 years ago, this industry didn’t exist at all and wouldn’t exist today if not for Max and Bennett.

Education

Two educational venues offered classes for genetic genealogists and have made their presentations available either for free or very reasonably.  One of the problems with genetic genealogy is that the field is so fast moving that last year’s session, unless it’s the very basics, is probably out of date today.  That’s the good news and the bad news.

Ancestor Reconstruction – Raising the Dead

This seems to be the year that genetic genealogists are beginning to reconstruct their ancestors (on paper, not in the flesh) based on the DNA that the ancestors passed on to various descendants.  Those segments are “gathered up” and reassembled in a virtual ancestor.

I utilized Kitty Cooper’s tool to do just that.

http://dna-explained.com/2014/10/03/ancestor-reconstruction/

henry bolton probablyI know it doesn’t look like much yet but this is what I’ve been able to gather of Henry Bolton, my great-great-great-grandfather.

Kitty did it herself too.

http://blog.kittycooper.com/2014/09/segment-mapper-tool-improvements-another-wold-dna-map/

Ancestry.com wrote a paper about the fact that they have figured out how to do this as well in a research environment.

GedMatch has created a tool called, appropriately, Lazarus that does the same thing, gathers up the DNA of your ancestor from their descendants and reassembles it into a DNA kit.

Blaine Bettinger has been working with and writing about his experiences with Lazarus.

Tools

Speaking of tools, we have some new tools that have been introduced this year as well.

Genome Mate is a desktop tool used to organize data collected by researching DNA comparsions and aids in identifying common ancestors.  I have not used this tool, but there are others who are quite satisfied.  It does require Microsoft Silverlight be installed on your desktop.

The Autosomal DNA Segment Analyzer is available through www.dnagedcom.com and is a tool that I have used and found very helpful.  It assists you by visually grouping your matches, by chromosome, and who you match in common with.

adsa cluster 1

Charting Companion from Progeny Software, another tool I use, allows you to colorize and print or create pdf files that includes X chromosome groupings.  This greatly facilitates seeing how the X is passed through your ancestors to you and your parents.

x fan

WikiTree is a free resource for genealogists to be able to sort through relationships involving pedigree charts.  In November, they announced Relationship Finder.

Probably the best example I can show of how WikiTree has utilized DNA is using the results of King Richard III.

wiki richard

By clicking on the DNA icon, you see the following:

wiki richard 2

And then Richard’s Y, mitochondrial and X chromosome paths.

wiki richard 3

Since Richard had no descendants, to see how descendants work, click on his mother, Cecily of York’s DNA descendants and you’re shown up to 10 generations.

wiki richard 4

While this isn’t terribly useful for Cecily of York who lived and died in the 1400s, it would be incredibly useful for finding mitochondrial descendants of my ancestor born in 1802 in Virginia.  I’d love to prove she is the daughter of a specific set of parents by comparing her DNA with that of a proven daughter of those parents!  Maybe I’ll see if I can find her parents at WikiTree.

Kitty Cooper’s blog talks about additional tools.  I have used Kitty’s Chromosome mapping tools as discussed in ancestor reconstruction.

Felix Chandrakumar has created a number of fun tools as well.  Take a look.  I have not used most of these tools, but there are several I’ll be playing with shortly.

Exits and Entrances

With very little fanfare, deCODEme discontinued their consumer testing and reminded people to download their date before year end.

http://dna-explained.com/2014/09/30/decodeme-consumer-tests-discontinued/

I find this unfortunate because at one time, deCODEme seemed like a company full of promise for genetic genealogy.  They failed to take the rope and run.

On a sad note, Lucas Martin who founded DNA Tribes unexpectedly passed away in the fall.  DNA Tribes has been a long-time player in the ethnicity field of genetic genealogy.  I have often wondered if Lucas Martin was a pseudonym, as very little information about Lucas was available, even from Lucas himself.  Neither did I find an obituary.  Regardless, it’s sad to see someone with whom the community has worked for years pass away.  The website says that they expect to resume offering services in January 2015. I would be cautious about ordering until the structure of the new company is understood.

http://www.dnatribes.com/

In the last month, a new offering has become available that may be trying to piggyback on the name and feel of DNA Tribes, but I’m very hesitant to provide a link until it can be determined if this is legitimate or bogus.  If it’s legitimate, I’ll be writing about it in the future.

However, the big news exit was Ancestry’s exit from the Y and mtDNA testing arena.  We suspected this would happen when they stopped selling kits, but we NEVER expected that they would destroy the existing data bases, especially since they maintain the Sorenson data base as part of their agreement when they obtained the Sorenson data.

http://dna-explained.com/2014/10/02/ancestry-destroys-irreplaceable-dna-database/

The community is still hopeful that Ancestry may reverse that decision.

Ancestry – The Chromosome Browser War and DNA Circles

There has been an ongoing battle between Ancestry and the more seasoned or “hard-core” genetic genealogists for some time – actually for a long time.

The current and most long-standing issue is the lack of a chromosome browser, or any similar tools, that will allow genealogists to actually compare and confirm that their DNA match is genuine.  Ancestry maintains that we don’t need it, wouldn’t know how to use it, and that they have privacy concerns.

Other than their sessions and presentations, they had remained very quiet about this and not addressed it to the community as a whole, simply saying that they were building something better, a better mousetrap.

In the fall, Ancestry invited a small group of bloggers and educators to visit with them in an all-day meeting, which came to be called DNA Day.

http://dna-explained.com/2014/10/08/dna-day-with-ancestry/

In retrospect, I think that Ancestry perceived that they were going to have a huge public relations issue on their hands when they introduced their new feature called DNA Circles and in the process, people would lose approximately 80% of their current matches.  I think they were hopeful that if they could educate, or convince us, of the utility of their new phasing techniques and resulting DNA Circles feature that it would ease the pain of people’s loss in matches.

I am grateful that they reached out to the community.  Some very useful dialogue did occur between all participants.  However, to date, nothing more has happened nor have we received any additional updates after the release of Circles.

Time will tell.

http://dna-explained.com/2014/11/18/in-anticipation-of-ancestrys-better-mousetrap/

http://dna-explained.com/2014/11/19/ancestrys-better-mousetrap-dna-circles/

DNA Circles 12-29-2014

DNA Circles, while interesting and somewhat useful, is certainly NOT a replacement for a chromosome browser, nor is it a better mousetrap.

http://dna-explained.com/2014/11/30/chromosome-browser-war/

In fact, the first thing you have to do when you find a DNA Circle that you have not verified utilizing raw data and/or chromosome browser tools from either 23andMe, Family Tree DNA or Gedmatch, is to talk your matches into transferring their DNA to Family Tree DNA or download to Gedmatch, or both.

http://dna-explained.com/2014/11/27/sarah-hickerson-c1752-lost-ancestor-found-52-ancestors-48/

I might add that the great irony of finding the Hickerson DNA Circle that led me to confirm that ancestry utilizing both Family Tree DNA and GedMatch is that today, when I checked at Ancestry, the Hickerson DNA Circle is no longer listed.  So, I guess I’ve been somehow pruned from the circle.  I wonder if that is the same as being voted off of the island.  So, word to the wise…check your circles often…they change and not always in the upwards direction.

The Seamy Side – Lies, Snake Oil Salesmen and Bullys

Unfortunately a seamy side, an underbelly that’s rather ugly has developed in and around the genetic genealogy industry.  I guess this was to be expected with the rapid acceptance and increasing popularity of DNA testing, but it’s still very unfortunate.

Some of this I expected, but I didn’t expect it to be so…well…blatant.

I don’t watch late night TV, but I’m sure there are now DNA diets and DNA dating and just about anything else that could be sold with the allure of DNA attached to the title.

I googled to see if this was true, and it is, although I’m not about to click on any of those links.

google dna dating

google dna diet

Unfortunately, within the ever-growing genetic genealogy community a rather large rift has developed over the past couple of years.  Obviously everyone can’t get along, but this goes beyond that.  When someone disagrees, a group actively “stalks” the person, trying to cost them their employment, saying hate filled and untrue things and even going so far as to create a Facebook page titled “Against<personname>.”  That page has now been removed, but the fact that a group in the community found it acceptable to create something like that, and their friends joined, is remarkable, to say the least.  That was accompanied by death threats.

Bullying behavior like this does not make others feel particularly safe in expressing their opinions either and is not conducive to free and open discussion. As one of the law enforcement officers said, relative to the events, “This is not about genealogy.  I don’t know what it is about, yet, probably money, but it’s not about genealogy.”

Another phenomenon is that DNA is now a hot topic and is obviously “selling.”  Just this week, this report was published, and it is, as best we can tell, entirely untrue.

http://worldnewsdailyreport.com/usa-archaeologists-discover-remains-of-first-british-settlers-in-north-america/

There were several tip offs, like the city (Lanford) and county (Laurens County) is not in the state where it is attributed (it’s in SC not NC), and the name of the institution is incorrect (Johns Hopkins, not John Hopkins).  Additionally, if you google the name of the magazine, you’ll see that they specialize in tabloid “faux reporting.”  It also reads a lot like the King Richard genuine press release.

http://urbanlegends.about.com/od/Fake-News/tp/A-Guide-to-Fake-News-Websites.01.htm

Earlier this year, there was a bogus institutional site created as well.

On one of the DNA forums that I frequent, people often post links to articles they find that are relevant to DNA.  There was an interesting article, which has now been removed, correlating DNA results with latitude and altitude.  I thought to myself, I’ve never heard of that…how interesting.   Here’s part of what the article said:

Researchers at Aberdeen College’s Havering Centre for Genetic Research have discovered an important connection between our DNA and where our ancestors used to live.

Tiny sequence variations in the human genome sometimes called Single Nucleotide Polymorphisms (SNPs) occur with varying frequency in our DNA.  These have been studied for decades to understand the major migrations of large human populations.  Now Aberdeen College’s Dr. Miko Laerton and a team of scientists have developed pioneering research that shows that these differences in our DNA also reveal a detailed map of where our own ancestors lived going back thousands of years.

Dr. Laerton explains:  “Certain DNA sequence variations have always been important signposts in our understanding of human evolution because their ages can be estimated.  We’ve known for years that they occur most frequently in certain regions [of DNA], and that some alleles are more common to certain geographic or ethnic groups, but we have never fully understood the underlying reasons.  What our team found is that the variations in an individual’s DNA correlate with the latitudes and altitudes where their ancestors were living at the time that those genetic variations occurred.  We’re still working towards a complete understanding, but the knowledge that sequence variations are connected to latitude and altitude is a huge breakthrough by itself because those are enough to pinpoint where our ancestors lived at critical moments in history.”

The story goes on, but at the bottom, the traditional link to the publication journal is found.

The full study by Dr. Laerton and her team was published in the September issue of the Journal of Genetic Science.

I thought to myself, that’s odd, I’ve never heard of any of these people or this journal, and then I clicked to find this.

Aberdeen College bogus site

About that time, Debbie Kennett, DNA watchdog of the UK, posted this:

April Fools Day appears to have arrived early! There is no such institution as Aberdeen College founded in 1394. The University of Aberdeen in Scotland was founded in 1495 and is divided into three colleges: http://www.abdn.ac.uk/about/colleges-schools-institutes/colleges-53.php

The picture on the masthead of the “Aberdeen College” website looks very much like a photo of Aberdeen University. This fake news item seems to be the only live page on the Aberdeen College website. If you click on any other links, including the link to the so-called “Journal of Genetic Science”, you get a message that the website is experienced “unusually high traffic”. There appears to be no such journal anyway.

We also realized that Dr. Laerton, reversed, is “not real.”

I still have no idea why someone would invest the time and effort into the fake website emulating the University of Aberdeen, but I’m absolutely positive that their motives were not beneficial to any of us.

What is the take-away of all of this?  Be aware, very aware, skeptical and vigilant.  Stick with the mainstream vendors unless you realize you’re experimenting.

King Richard

King Richard III

The much anticipated and long-awaited DNA results on the remains of King Richard III became available with a very unexpected twist.  While the science team feels that they have positively identified the remains as those of Richard, the Y DNA of Richard and another group of men supposed to have been descended from a common ancestor with Richard carry DNA that does not match.

More Alike than Different

One of the life lessons that genetic genealogy has held for me is that we are more closely related that we ever knew, to more people than we ever expected, and we are far more alike than different.  A recent paper recently published by 23andMe scientists documents that people’s ethnicity reflect the historic events that took place in the part of the country where their ancestors lived, such as slavery, the Trail of Tears and immigration from various worldwide locations.

23andMe European African map

From the 23andMe blog:

The study leverages samples of unprecedented size and precise estimates of ancestry to reveal the rate of ancestry mixing among American populations, and where it has occurred geographically:

  • All three groups – African Americans, European Americans and Latinos – have ancestry from Africa, Europe and the Americas.
  • Approximately 3.5 percent of European Americans have 1 percent or more African ancestry. Many of these European Americans who describe themselves as “white” may be unaware of their African ancestry since the African ancestor may be 5-10 generations in the past.
  • European Americans with African ancestry are found at much higher frequencies in southern states than in other parts of the US.

The ancestry proportions point to the different regional impacts of slavery, immigration, migration and colonization within the United States:

  • The highest levels of African ancestry among self-reported African Americans are found in southern states, especially South Carolina and Georgia.
  • One in every 20 African Americans carries Native American ancestry.
  • More than 14 percent of African Americans from Oklahoma carry at least 2 percent Native American ancestry, likely reflecting the Trail of Tears migration following the Indian Removal Act of 1830.
  • Among self-reported Latinos in the US, those from states in the southwest, especially from states bordering Mexico, have the highest levels of Native American ancestry.

2015

So what does 2015 hold? I don’t know, but I can’t wait to find out. Hopefully, it holds more ancestors, whether discovered through plain old paper research, cousin DNA testing or virtually raised from the dead!

What would my wish list look like?

  • More ancient genomes sequenced, including ones from North and South America.
  • Ancestor reconstruction on a large scale.
  • The haplotree becoming fleshed out and stable.
  • Big Y sequencing combined with STR panels for enhanced genealogical research.
  • Improved ethnicity reporting.
  • Mitochondrial DNA search by ancestor for descendants who have tested.
  • More tools, always more tools….
  • More time to use the tools!

Here’s wishing you an ancestor filled 2015!

 

Family Tree DNA – Final Mystery Rewards Coupon

happy holidays

Did you receive money in your Christmas stocking?  Well, now is the time to spend it during the last 3 days of Family Tree DNA’s holiday sale.

New coupons were issued today, but it seems that while Christmas is over, April Fool’s Day has arrived early.

There was a bit of an error in the Mystery Rewards notification e-mails sent today.

From Family Tree DNA:

If you received an email about a Mystery Reward that showed no discount and that the reward was expired, please disregard it.

****PLEASE LOG DIRECTLY INTO THE KIT TO GET THE VALID MYSTERY REWARD CODE.*****

We apologize for any confusion or inconvenience this may have caused.

So, never mind the e-mail and click here to sign in to your account and click on your mystery reward gift box one last time!  Post any codes you’re willing to share in the comments.  And remember, the sale ends at midnight, Houston time, on the 31st.

Happy New Year!

Family Tree DNA Mystery Rewards – Week 5 – Merry Christmas

ftdna mystery reward package

This posting should be subtitled, “oh, my aching credit card.”

But this sale, and these coupons, have just been too good to pass up.  Given that Christmas is this week, and these coupons expire on 12-28-2014, it’s doubtful that there will be additional coupons issued on 12-29, but that has not been confirmed by Family Tree DNA – just my speculation.  The holiday sale ends on December 31st.

One of the things I’ve learned this past year is just how valuable it is to test cousins….and I mean autosomally testing every single cousin you can get your hands on.

Why?

Because those cousins are going to match people that you aren’t.  Each cousin may be the person to hold that gold nugget of ancestral DNA that you’re going to need to break down that brick wall.

I just had that experience myself, if you’ve been reading along.  If not, this article about my new Hickerson cousin will warm your heart.  And the really important part – Bill Hickerson did not match me at Family Tree DNA, he matched one of my cousins.  My Vannoy family has a group of about 20 people that we’ve convinced to test and that cousin cluster has proved invaluable.  We simply could not have broken this brick wall without the cousins!

We’re doing the same cousin cluster research approach with the Henry Bolton line and maybe, if we’re lucky, thanks to cousins, we may have more news on this line in 2015.  We’re within sniffing distance.

So, I can’t say this loudly enough – TEST YOUR COUSINS.

And I mean – EVERY COUSIN.

Yes, pay for it if you have to.  Merry Christmas to you (or however you celebrate whatever holiday you celebrate) – it’s the gift that keeps on giving.  Maybe a great way to spend any $$ found in your stocking!

Just think of it as a new reference book, or costing much less than a trip to a distant courthouse.

And don’t forget, if you discover that cousins have already tested at Ancestry or at 23andMe with the V3 chip, you can use one of the general $5 or $10 off coupons to transfer their results to Family Tree DNA – which drops the cost below the normal $39 (to $29 or $34) to unlock the results.

Here’s wishing you many newfound cousins and ancestors in the coming year!

All New Mystery Coupons – Week 4 Family Tree DNA Holiday Sale

will work for dna tests

Great news!  All new coupons this week for everyone at Family Tree DNA, so check your mystery gift box on your personal page.

Yesterday I received an e-mail from a store that says “10 days until Chrismas.”  Ah, the panic begins.

It’s easy and convenient to shop online.  And of course, sales and coupons sweeten the pie.

I’ve found several cousins to DNA test.  Those cousin tests have proven again and again to be the key to answering genetic genealogy questions and breaking down brick walls.

In fact, I’ve bought so many kits for others that I’m beginning to think that “Will Work for DNA Tests” is somehow appropriate – that’s how it feels anyway.

Lots of good coupon trading going on….so click here to sign on and post what you have or what you need in the comments.

As for me, I still need two $20 Family Finder coupons because yes, there are MORE cousins to test!!!  I sure am grateful for this sale and these coupons!  I hope everyone is going testing crazy – just think how many more people will be in the matching data base soon!!!

Family Tree DNA Week 3 Mystery Coupon Same as Week 2

Four Red Gift Boxes

This week’s mystery coupon seems to be the same for everyone as last week’s, but with a new coupon code and a new expiration date.

Update – A few people are reporting different coupons.

That’s kind of disappointing, because we can’t order the same test twice and I know a lot of people were hoping for a particular coupon.  So, what that means is that sharing becomes even more important – and it also suggests that maybe, just maybe, some of those high dollar “good” coupons will be floating around this week because the recipient used theirs last week.  Hey, this may not be so disappointing after all!

Remember, the general coupons are good on new kit purchases too.  If your family members haven’t tested, Christmas would be a good time – and while it’s a gift for them, it’s a gift for you too!

My children tested at 23andMe when testing was first available.  Those early kits don’t transfer to Family Tree DNA (and neither do v4 tests since November 2013), so maybe I’ll order two Family Finder kits for them.  As we move forward in this field, understanding generational inheritance becomes even more important, and immediate family is the best information source you can have!!!
