An article recently published in Nature Communications confirmed the identity of the remains of King Richard III by DNA testing. This result wasn’t a huge surprise, but there were some eyebrow-raising findings along the way. More to the point, now a celebrity case study teaches us more about how to use DNA in family history research.
Prior to the genetic investigation of the skeletal remains presumed to be that of Plantagenet King Richard III, there was already mounting evidence that this was indeed his body. Genetic genealogists can take cues from this research to learn how to more fully integrate your genetic testing into your genealogy.
While these researchers were able to use radiocarbon dating and skeletal analysis methods that most of us won’t have access to, they did pore over a substantial amount of historical evidence to substantiate the last known whereabouts of Richard III. The archaeological, skeletal, and historical evidence were overwhelmingly in favor of this positive identification. But it was the genetic evidence that provided the last, ahem, nail in the coffin.
In this case the nail was made of mitochondrial DNA, or mtDNA. King Richard shares his mtDNA with anyone who is also related in a direct maternal line to his mother. There were two such candidates found, both sharing mtDNA with the skeleton presumed to be King Richard, thus further verifying its identity. In fact, lead researcher Turi King said of the findings, “If you put all the data together, the evidence is overwhelming that these are the remains of Richard III.”
Of interesting note to us as genetic genealogists is that one of the two mtDNA samples used for reference did have one difference from the mtDNA signature shared by the other individual and the skeleton. This did not jeopardize the integrity of the results, but rather provided a good case study in how DNA does change over time.
You would think that the DNA match confirming the identity of the skeleton would be the biggest news out of this round of DNA testing. But along with the direct maternal line testing, there was also direct paternal line testing to try to verify the paternal line of the skeleton.
Genealogists worked tirelessly to identify direct paternal descendants of Richard III’s great-great grandfather Edward III and five were found and tested. Their results revealed not one but THREE different paternal lines.
While the results were not quite as expected, they weren’t exactly unexpected either, as there are plenty of royal rumors of non-paternity (click here for a summary). Watch a brief video discussion of the yDNA results here:
Again, the YDNA portion of the study provides a great case study for us in how to use YDNA, namely that it takes a lot of traditional genealogical work to find direct paternal line descendants to be tested, and that the results are conclusive, but can sometimes provide more questions than answers.

“Knowing your genealogical question can make DNA testing for adoptees (and anyone else) more focused and relevant. Being patient and determined—not quitting after a single test’s results—can also pay off, as it did for Paul Dobbs, a Welsh-born man who followed his adoptive father to Canada only to learn he was fathered by a U.S. serviceman.”
Paul Dobbs didn’t find out that Len Dodds wasn’t his biological father until after the man who’d raised him to adulthood passed away. The truth came out during a genetic investigation into Len’s rare medical condition. He learned that he was child of an American soldier stationed in Wales during World War II. But years of traditional genealogical research led to dead ends. Then Paul turned to DNA and found a match: a first cousin.
With the help of his new-found cousin and the traditional genealogical records available about servicemen serving in Cardiff at the end of World War II, Paul was able to form a convincing hypothesis about the identity of his biological father.
He reached out to a potential half sibling who agreed to conduct a DNA test to explore this option.
She was a match. Paul had found his biological family! (Read his story in the Vancouver Sun.)
Not everyone will find their birth parents through DNA testing. But Paul took an approach that can serve anyone looking for biological kin through DNA. His experience reminds us that knowing your genealogical question can make DNA testing more focused and relevant. Being patient and determined—not quitting after a single test’s results—can also pay off, as it did for Paul.
For any male adoptee seeking his father, the yDNA test is a logical route to take. This is where Paul turned first. The yDNA provides an undiluted record of a direct paternal line. This can often help adoptees identify a surname for their paternal line. However, Paul did not have the success he was hoping for with yDNA testing.
He then turned to autosomal DNA testing. Remember that this kind of test traces both your paternal and maternal lines and reports back to you matches in the database that have predicted relationships like, “2-4th cousins” or “3rd-5th cousins” and then you are left to decipher who your common ancestor might be.
DNA testing is a great option for adoptees to get a jumpstart on their genealogy. However, before testing, everyone, adoptees included, should carefully consider how the results of testing may impact you and your family, both biological and adopted.

“This is really the first time a DNA testing company has so fully integrated genetics and genealogy. We can now find cousins in the database who do not share our particular genetics, but who do share some of the genetics of our common ancestor. This is huge.” -Diane Southard, Your DNA Guide
I blogged a couple of weeks ago about some changes taking place over at AncestryDNA
. You will recall that they are planning to slash your match list 
to allow only “invited guests” to your personal DNA party. (Read that post to be reminded why this is a good thing.)
Ancestry has officially announced the launch of this feature update and reports that on average users will see an 80% reduction in the number of matches shown. I had a chance to look at the new site before it launched and one of my favorite features is the question mark that appears next to your match. Clicking on the question mark on your match page will bring up a menu of references to help you better understand the inner workings of matching at Ancestry, including those confidence levels that are a part of every relationship prediction. In this table below you can see that ancestry has tried to give you some fairly solid guidelines by which to assess the quality of your matches. You will want to focus on those matches with a confidence score of “High” or above to have the best chance of genealogical success. 
But an update to the matching feature is only the beginning of the new features at AncestryDNA. Today Ancestry announced “DNA Circles,” a tool that helps you identify others who share common ancestors with you. The new “DNA Circles” feature has the potential to impact the way you do genetic genealogy at Ancestry. Here’s why: Autosomal DNA (the kind that Ancestry is testing) has a spotty inheritance pattern. On average we only have half of the DNA of each of our parents, only 25% of our grandparents, only 12.5% of our great grandparents and so on. This means that AncestryDNA and its competitors (Family Tree DNA and 23andMe) are only able to genetically identify 50% of your genetic 4th cousins. This means that there could be 50% MORE people in these databases that you are actually related to, people that should have been invited to your DNA party, but didn’t have a ticket. Now with DNA Circles, there is a metaphorical “after-party.” After parties are “hosted” by one of your relatives. Ancestry searches your pedigree and that of your matches back 7 generations looking for suitable hosts. An ancestor qualifies as a host if they have two or more descendants who hold an invitation. At this after-party you can meet some of these long lost cousins that, while related to you, lost their ticket to your DNA party. After-party invitations are provided to those who meet three very important qualifications:
- They have their DNA attached to their PUBLIC family tree.
- AND that PUBLIC family tree has the name of the hosting ancestor on it.
- AND this person shares DNA with at least one other person who also meets the above two criteria.
Here’s an example. Below is an image of the new AncestryDNA home page. You can see I am a part of two DNA Circles (some of you will be much more popular and invited to several after-parties. For me–just the two for now). Let’s take a closer look at my DNA Circle hosted by my paternal 5th great grandfather Minus Griggs (who knew the guy liked parties?!). 
Clicking on the DNA circle brings up this page where there are three things I want to show you: 
- This is your relationship to the host.
- This is a list of the individuals who have passed the three criteria listed above and have been invited to this after-party.
- This is the innovative part. You see that the first two matches (after me–I am listed first) have only “Tree Match” in this column. This means that these two people, both descendants of our host, Minus Griggs, didn’t ever appear on my DNA match list. We do not share enough DNA to be considered genetic relatives. However, the third member of the circle has the “DNA Match” designation, meaning that this match DOES appear on my match page. In fact, this is my ONLY DNA match in the circle (there are three others not shown here). That means that this DNA circle has connected me to FIVE other cousins. All because I share DNA and genealogy with the third member of this circle, and he shares DNA and genealogy with everyone else.
I can click on each circle member to see exactly how Ancestry THINKS we are related. This is my first opportunity to DOUBLE CHECK this relationship that Ancestry has handed me, to be sure that both my match and I really did receive tickets to the same after party.
Here is what that page looks like for me and one of my matches.
This is really the first time a DNA testing company has so fully integrated genetics and genealogy. We can now find cousins in the database who do not share our particular genetics, but who do share some of the genetics of our common ancestor. In my opinion, this is huge.
There is one catch, and it is going to be a big one for some of you. In order to see your DNA Circles, you have to be an Ancestry.com subscriber.
Even though I am excited about these changes, I can’t help but hope for just one step more. In order to identify these DNA Circles, Ancestry has identified pieces of DNA that can be fairly reliably assigned to a particular ancestor. There are likely others in the Ancestry database who have these pieces of DNA, we can call them partial tickets to the after-party, but who are lacking the second requirement: a pedigree documenting a relationship to that ancestor. I hope in the future the folks at Ancestry will honor those partial ticket holders, and allow them to the after-party, so we can sit around with our peanuts and pretzels and figure out how we are all related. Until then, I am going to enjoy the two after-parties hosted by my two generous ancestors.

You may recall from our recent DNA discussion on the Genealogy Gems podcast (Episode 168) that Ancestry.com recently discontinued their mtDNA and YDNA tests (the two that trace our direct maternal and direct paternal lines) to focus on autosomal DNA (which delivers information about both your mother’s and your father’s side of your ancestral tree).
Well, recently I attended an all-day meeting hosted by Ancestry.com: a summit to talk about current trends and accomplishments at Ancestry DNA
, and ideas about the future of DNA testing at Ancestry.com.
The meeting included a diverse group of Ancestry representatives, from CEO Tim Sullivan to members of the marketing, scientific, communications, and even computer science departments, as well as some of the top voices in genetic genealogy. It was an open and lively discussion, and I walked away with a few gems I want to share with you today.
More Powerful DNA Hints Coming
In AncestryDNA, the ‘shaky leaf” hints are meant to help you find a common ancestor between you and your DNA matches. The computer code behind the old hints was not very efficient. Lazy, in fact. It started at the bottom of your tree—and the bottom of your match’s tree—and slapped on a shaky leaf at the first sign of a shared common ancestor.
While this method worked for a large number of cases, it was leaving a lot of stones unturned. But the IT guys at Ancestry have beefed up the computer power, allowing them to cover a much greater distance through our trees and the trees of our matches before making a judgment about the best place to assign that shaky leaf.
The result? Better hints about how you and your match COULD be related. Remember, the leaf is still just a SUGGESTION on how you and your match might be related. It is not a crystal ball.
Did You Know?
- Ancestry DOES store your DNA samples in a secure location.
- Ancestry spent months designing their own DNA collection kit.
- Ancestry was able to attract some of the brightest scientists in the field of population genetics because of YOU. You with your documented pedigree charts and your willingness to help move this science of discovering our ancestors forward.
Looking Ahead
There is no question that the genetic genealogy industry is rapidly advancing, and our discussion with Ancestry certainly didn’t disappoint. While I will be sharing with you in future posts about some of the exciting changes, I do want you to be ready for one that buy anxiety medication online uk will be coming online fairly soon.
It has to do with your matches. If you have been tested by AncestryDNA, you may have been initially excited, then nearly immediately overwhelmed, by the number of individuals listed in your match page, all claiming to have some kind of connection to you and your family tree.
All three major genetic genealogy testing companies (AncestryDNA, Family Tree DNA, and 23andMe) are using basically the same laboratory methods to glean information from your DNA. What differs is how they use that data to draw conclusions about your ethnic heritage and about your relationships to other individuals. As it turns out, AncestryDNA has been reporting far more individuals as your relatives than it should have.
You can think of it like this: You have sent out tickets, in the form of your genetic code, to an exclusive party where you (of course!) are the star. However, you have lost the guest list and you are counting on the testing company to check the ticket of each guest before they enter your party to be sure they were really invited.
AncestryDNA was relatively new in the role of party bouncer, and in the interest of not turning away any VIP guests, they initially allowed guests into your party who had (gasp!) forged tickets!! But as AncestryDNA admits more guests, the experience it’s gained in party monitoring is starting to show.
You see, each of the forged tickets has some unique qualities that have started to send up red flags to the team of scientists at AncestryDNA. They are now in the process of carefully documenting what each forged ticket looks like and tossing those unwanted guests out on their ear.
The short of it: in the near future your match list at Ancestry will be much shorter. Which is good news to you, as it means only those invited genetic cousins will be around eating hors d’ oeuvres and ready to talk about your shared common ancestry.
Each testing company has its strengths and weaknesses. It was good to have a bit of insight into this one company and come to a greater understanding about why it is they do what they do. It is a great time to be in this young genetic genealogy industry, with so much room to grow and change. I will let you know when I find the next genetic gem.

Two women born from the same womb lived their lives entirely separately–until recently, when these long-lost twins reunited.
TheBlaze.com reported on and followed up with a BBC video of the happy reunion. The article says the women set a world record for the longest-known separated twins. The women are likely fraternal twins, but at the time of the article, were awaiting DNA test results.
According to TheBlaze, “Both women were born in Aldershot, England, in 1936. Their mother, a domestic servant, decided to give up one of the girls after their birth father fled. [Elizabeth Hamel, the twin who was not adopted out] said she [the mom] kept her because she was born with curvature of the spine, which would have made it more difficult for her to be adopted.”
The article explains that Hamel grew up knowing she had a twin but never expecting to see her. Eventually she married an American and moved to the U.S. Meanwhile, her sister, Ann Hunt, was adopted and raised in England. She only learned about a year ago that she had a twin.
What a moving story! Ann and Elizabeth sure have a lot to catch up on. And how interesting to see sleuthing skills we use in genealogy–like a search for a mother and DNA testing to confirm relatedness–put into action to strengthen ties among living relatives.
