As genealogists, we spend our time trying to ferret out the real story in our family’s oral history, or at least from the records they left behind. Record research is critical, but now we have an amazing new tool…DNA matching.
Genealogists constantly check family stories against the information on records, searching for what sounds plausible and what doesn’t. Even when we have total agreement in our records, more information often comes along…like DNA testing. In fact, DNA matching may shed light on even more apparent discrepancies.
Family Lore vs. DNA Findings
I recently read an article in the Wall Street Journal about a reporter, Cameron McWhirter, who shared finding that kind of discrepancy between his family lore and his DNA. He even goes so far as to say, “I am descended, at least partially, from liars.” He makes the point, “many immigrants reinvented themselves when they arrived here (the United States).” This could be a nice way of saying they had a chance to invent a new legacy, not just re-invent it. His assessments were certainly interesting and worth reviewing. It helps us see how DNA testing can affect the way we look at our family stories and traditional research results.
McWhirter may be like some folks today who have never set foot inside a courthouse or scanned through microfilm, but instead relies heavily on internet research. Some of these modern genealogists never gave their family history a second thought until, like McWhirter, the death of parents started to inspire them to dig deeper. Due to the large volume of information online, the budding genealogist is “quickly pulled into the obsessive world of modern genealogical research.”
Example of an ethnicity report from Ancestry.com.
McWhirter’s personal story was that while his dad was proudly and solidly a self-proclaimed Scot, the records and DNA matching revealed his heritage was actually from Ireland and eastern Europe. McWhirter says that his “father hated Notre Dame, but judging by my results he could have been one-quarter to one-half Irish. He spoke dismissively of people from Eastern Europe, but part of his genetic code likely came from that region.”
McWhirter’s evaluation of his genetic report includes only his ethnicity results, which as you can hear, were meaningful to him in the way that flew in the face of his father’s prejudices and assertions of his own identity.
However, the ethnicity results fall short of the point of testing for most genealogists.
He has the opportunity to more powerfully transform his sense of family identity by taking a look at his match list. Here, he may see an actual living cousin who was also descended from his German great-grandmother, who maybe never mentioned that she was also Jewish.
The Real Goal: DNA Connections to Living Family
Connecting with other cousins who also have paper trails to our ancestors serves to provide further confidence that we have put all the pieces together and honored the right ancestor with a spot on our pedigree chart. We multiply our own research efforts by finding more people like us—literally—who are descended from the same people. As long as they are as diligent in their research as we are, we can make these connections that could finally bust through those genealogy brick walls and more.
At a recent conference, I met a fifth-cousin. Even with a connection that distant, it was exciting and it encouraged us to want to look again at our connecting ancestors. To me, that is the bigger picture and the real goal—when the paper trail comes together with the DNA results and turns into real live cousins.
The Next Step: Using Your DNA Results to Find Living Family
Maybe you are like Cameron McWhirter: you’ve taken a DNA test, been intrigued or disappointed by the ethnicity results, but haven’t fully explored your matches on your list. You may be seriously missing some opportunities! If that is you, I have written my new DNA quick guide just for you. It’s called “Next Steps: Working with Your Autosomal DNA Matches.” This guide will teach you how to leverage the power of known relatives who have been tested. You will get an intro to chromosome browsers and their role in the search process and access to a free bonus template for evaluating genealogical relationship of a match to the predicted genetic relationship. This guide also gives you a methodology for converting unknown relatives on your match list into known relatives.
So check it out, either by itself or as part of my Advanced DNA bundle, which comes along with my new Gedmatch guide and a guide expressly for organizing your DNA matches.
by Diahan Southard | Jan 17, 2015 | 01 What's New, DNA
(Update 2020) When genealogists take an ancestry DNA test, they are looking for more than just their ethnicity results. They are also very interested in receiving information on other people who have tested who closely genetically match them. They want to know who the closest matches are, and if those matches have family tree information that they can share.
However, with all the people testing these days, (some being genealogists and some not) the volume of matches can become overwhelming very quickly.
Are you one of those people who have way too many genetic “4th cousins or closer” among your DNA matches? Have you ever wondered “What do I do with all these matches?!” If so, keep reading. We’re going to explore some of your options, and most importantly, how to determine how genetically close your cousins really are.
Doing the DNA Math on Your Cousins
Math can provide us with a degree of certainty in genetic genealogy. Each of us has two biological parents. We have four biological grandparents, and eight great-grandparents.
However, the farther back we go the less we can rely on math.
For example, on paper you should have sixty-four 3rd great grandparents. However, many of us find that the same person occupies more than one slot on our pedigree chart. While this significantly decreases the workload for traditional genealogy, it adversely impacts your genetic genealogy. Especially when it comes to that long long list of 4th cousins you have in your match list at any of the three major DNA testing companies.
Depending on how intermarried your lines are, you may be seeing individuals on your match list that genetically look like your fourth cousins, but they are genealogically your sixth cousins – EIGHT TIMES! So how can you tell the difference?
There are two parts to that answer: one you can control, and the other you can’t.
Distinguishing DNA Matches with Genetic Tools
While your fourth cousins and your eight-time-sixth cousins may look similar genetically, there are often small clues in the genetics that can help you tell the difference. This distinction can sometimes be detected by a testing company who, through research and validation, has been able to fine-tune their algorithms to detect these subtle differences.
Your Genetic 4th Cousins
You can participate in this double checking process by using some of the genetic tools that are available to you at Family Tree DNA, or at Gedmatch.com. But since you may not be an aspiring geneticist, let’s focus on the genealogical work you can do to determine if a match is truly a fourth cousin.
Use Google Earth to Plot Your DNA Matches
A fourth cousin designation just means that you and your match are separated by between six and twelve degrees (people). So that might be five back on your chart to your common ancestor, and five down to your match, which would make you true fourth cousins. It could also be some other permutation of that.
For our example, let’s assume true fourth cousins. That means that the two of you share one of thirty-two 3rd great grandparents (16 couples). In order to find out which set, you have two genealogical identifiers: surname and location.
Therefore, the first thing you should do is make a list of the surnames and locations of those thirty-two 3X great grandparents.
Now, most of us do not know all 16 of those couples, so you are going to have some holes. Feel free to fill in those holes with surnames on subsequent generations that will carry through to this fifth generation.
A great tool to plot your own list of ancestors geographically is the free downloadable Google Earth software.
Check to see if you have the latest version of Google Earth downloaded to your desktop or laptop computer. On your desktop, look for a grey and white globe. If you see a blue and white globe, you have the older original free version of Google Earth. However, a few years ago, Google made their Google Earth Pro version free to everyone, and it is now the standard.
If you do have Google Earth Pro (the grey globe software) then you’re ready to go.
The grey Google Earth globe on the desktop.
If you don’t have it, then you will need to download it.
How to Download the Free Google Earth Software:
- Go to http://www.google.com/earth/download/gep/agree.html
- Click the blue download button
- Read the Terms and Conditions
- If you agree to them, click the Agree and Download button
- Follow the installation guide
- When complete click Run Google Earth
Now that you have Google Earth, you can begin by creating a folder in the Places panel in Google Earth devoted to your 16 couples. Here’s how:
1. In the Places panel, right-click on MyPlaces and select Add > Folder:
Right-click on MyPlaces > Add > Folder
2. Name the folder and then click OK:
Creating a folder in Google Earth
3. Now you will see your new DNA folder for your 16 couples in the Places panel. If you don’t see it, look toward the bottom of the list. You can move the folder to any location within the list by dragging and dropping it.
Create a folder in Google Earth for DNA 16 couples
Once you have your DNA folder created fro your 16 couples, you can then easily plot your surnames and locations.
How to Plot Your Surnames and Locations in Google Earth:
1. Click your new DNA folder to select it. This will ensure that the placemark you are about to create will be stored in that folder.
2. In the search box (upper left corner of the Google Earth software) type in the first location and click Search. Google Earth will fly to that location on the map.
Type the locaton in the Search box and click Search.
3. In the toolbar along the top of the screen, click the placemark button to place a pushpin in that location:
Click the Placemark button in the Google Earth toolbar.
4. In the Placemark dialogue box, enter a title for hte pushpin placemark. Click the OK button to close the box and set your placemark.
5. Repeat the process for all the locations.
Then evaluate the fifth generation of your fourth cousin matches for genealogical information that lines up with any of the items on your list.
You can also plot the surnames and locations of your matches in Google Earth. This is where Google Earth really comes in handy. The free software makes it very easy to see when your ancestral home may be bordering the locations of your matches. Those with whom you find a similarity become your best matches, and your best chance of determining your connection. Those without an obvious connection cycle to the bottom of your pile for a genetic evaluation. You can perform these same kinds of searches for your second and third cousins as well.
As you begin to become more familiar with the fifth generations of your matches, you may also start to see patterns of surnames or locations emerge among your matches. These then become the surnames and locations that might be able to fill the missing spaces in your pedigree chart.

Authors: Diahan Southard and Lisa Louise Cooke
by Lisa Cooke | Jul 19, 2017 | 01 What's New, Ancestry, DNA |
An update to AncestryDNA’s privacy policy requires us to take to take one more step when managing someone else’s DNA test. Here’s why Your DNA Guide Diahan Southard thinks that’s a good thing.
Like many teenagers, my 14-year old sees every situation only from her own point of view. I call it myopic-itis. This is, of course, how most of us react to every new situation. The difference between those suffering from this condition and the rest of us is that fairly quickly, perhaps once the shock has subsided, we can see things from the point of view of others, and can therefore be more understanding about the whole situation.
AncestryDNA recently caused an attack of myopic-itis when they announced a change to their policy on how DNA tests are registered. Previously, you could register anyone’s test under your own account. Say you were gathering the test for an aged aunt or disinterested cousin. You handle everything from the order to the test registration to managing all correspondence. Your aunt or cousin merely needed to spit in the tube.
However, effective today, July 18, 2017, that has changed. Each person who takes an AncestryDNA test must have their very own account at AncestryDNA.
A natural reaction is to immediately reject this as a terrible idea that will certainly slow–if not halt–your efforts to gather the needed genetic information from your less-than-enthusiastic relatives. Your myopic-itis flares up and threatens to cause you to throw up your hands in frustration and just forget the whole thing.
But don’t! Really, all that is changed is that you have to take one more step when administering DNA tests for your friends or relatives: create AncestryDNA accounts for them. Then, they can assign you as the Manager of their DNA kits. Doing so allows their DNA results to show up in your Ancestry account, just as if you yourself had registered the test under your account. Viola! (Well, if your relative doesn’t have an email account, you may have to create one, so that would be one more step.)
Now, why would Ancestry decide to so inconvenience your life with another step or two? Well, to protect the rights of the cousin and the aunt that you are asking to take the test. It is that simple. Not that you would, but if the results are in your account, you can delete them, you can limit their access to them. In short, you have ultimate control. Causing each test to have its own account tries to put that control back in the hands of the test taker.
One of the criticisms of this announcement is that Ancestry is doing this just to make more people buy subscriptions to Ancestry. I don’t think this is their primary motivation. In fact, a blogger in the UK, Debbie Kennett, suggested that it may be partially in reaction to a new law in the UK that, starting next year, will require this personal access inr order for Ancestry to continue selling tests there.
But even if getting more subscribers was their primary motivation for the change, how is encouraging interest in genealogy a bad thing?! Think of it this way: let’s say you tell your cousins, “I got this. Don’t worry about anything. I will do it all.” Then they will let you, and they won’t take any ownership of the process or the results.
Instead, now you can say, “I have created a login for you at Ancestry so you can view your own results. I will also be able to see them in my account. I would love to go over them with you, if you are interested. But you can go in anytime and look around.” Then wouldn’t it be great if they really did that? Maybe they’d even get so interested that they’d decide to help you research?!
DNA is one of the biggest hooks we have to get our friends and family interested in family history. I think this change is just one more way that we can spread our love of family history with our family–not to mention protect their privacy and their rights.
In addition to Debbie Kennett’s post I mentioned above, make sure to read the official announcement by Ancestry, and these two blog posts about questions you may have: Reality Check–Changes at AncestryDNA and Managing Multiple Kits and the New AncestryDNA Change.

by Lisa Cooke | Dec 23, 2014 | 01 What's New, Adoption, DNA
“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.
