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.

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.

Your local library may offer free genealogy magazines and ebooks. Why choose them over print? So many reasons! No more late fees. Read on the go. Choose your font size. So go ahead: check out digital versions of that Genealogy Gems Book Club title you’ve been meaning to read, or the current issue of Family Tree Magazine. Here’s how.

Here in the U.S., it’s my favorite time of year: back-to-school! The weather slowly cools. My children shake off summer’s mental lethargy. My own schedule resumes a more predictable, productive rhythm. And after months spent outdoors, I rediscover my local library. Top on my library list this fall: free genealogy ebooks and magazines I can check out on my mobile device. It’s on-the-go reading for my favorite hobby–with no searching under my bed when items come due to avoid those pesky late fees.
Free Genealogy eBooks and Magazines
Genealogy Gems Premium Member Autumn feels the same way about free genealogy gems at her local library. Here’s a letter she wrote to Lisa Louise Cooke:
“I’m really enjoying both the Premium and free podcasts. I also like the addition of the Genealogy Gems Book Club. I haven’t read all the books yet but am adding them all to my wishlist on Overdrive, a free app that allows you to check out digital books for free from your local library. They don’t have every book but they have many, many books including some from the book club. Most libraries have a lot of biographies and histories available through Overdrive for free that are of interest to genealogists as well. Some libraries are adding video to their Overdrive offerings too.
Many of these same libraries offer magazines free as well. My library…use[s] Zinio, a magazine app. I only subscribe to a couple of magazines now because I can get so many for free through my library (not to mention keeping my home neater by not having them laying everywhere).”
It makes me happy that Autumn is enjoying the Genealogy Gems Book Club. We hear from many avid readers who love browsing our list of mainstream fiction and nonfiction picks for family history lovers. As part of our book club, we interview every book club author, too–from beloved novelists like Fannie Flagg to acclaimed journalists, memoir writers, and historians who take their own unique approaches to family history themes. Hear excerpts of these interviews on the free Genealogy Gems Podcast; full interviews run on the Genealogy Gems Premium Podcast, available by subscription.
Overdrive and Zinio
At Autumn’s recommendation, I started using Overdrive through my local library. I love it! I’ve listened to several digital audiobooks on the road and at the gym through Overdrive and have read several ebooks, too. (I’m always on the hunt for the next Genealogy Gems Book Club title.) The books just disappear at the end of the lending period (hence the “no late fees” bonus).
Genealogy Gems Service Manager Lacey Cooke loves Overdrive, too. She sent me these four reasons why:
1. Download for Offline Listening: “You can download the ebooks, audiobooks, magazines etc. to your device so that you can enjoy them offline (great for traveling). They’ll still disappear once your lending period expires, but having them available offline is awesome. You don’t have to worry about data charges or slow internet connections.
2. The Wishlist: Autumn briefly mentioned the Wishlist feature. I love this feature because it gives me somewhere to save book titles that I’m interested in reading at some point, but I’m not ready to check out just yet.
3. Bookmark/Syncing: You can bookmark a page, then pick up where you left off. If you have the Overdrive app on multiple devices, the app syncs. I can start reading on one device, and pick up on another right where I left off.
4. Format Adjustments: You can adjust the font style, size, and color to make it easier for you to read. I like to pick a nice, clean font in a big size so there’s no strain on my eyes.”
It’s worth noting that if you don’t already have a library card with your local library, you may be required to sign up in person to get a card, even if you only plan on using the Overdrive app to request items online. New releases or popular titles may have a wait list to check out the ebook or audiobook (especially if the library only possesses one copy). If you do have to place an ebook on hold, you will be notified via email when it becomes available to you, so if you don’t check your email regularly, keep that in mind when you place a hold. Each library system is different, so of course, your experience may vary.
Another helpful tip: not every library offers Overdrive ebook checkouts. But sometimes you can use another library’s Overdrive privileges. Autumn sent a link to these instructions on how to do so. (Thanks, Autumn!)
Autumn also mentioned the Zinio app. My library doesn’t offer Zinio yet, so I spent a little time on its public search portal. That doesn’t have a browsable genealogy category, and searches for the terms family history, genealogy and ancestry came up empty. But I did finally find these titles:

Lisa Louise Cooke, Genealogy Gems DNA expert Diahan Southard, and I are all frequent contributors to Family Tree Magazine, which we {heart} and recommend for its easy-reading research tips, hands-on tech and DNA tutorials, and the eye-candy layout.
More Free Genealogy Resources at Your Local Library
Of course, your local library may offer many additional free genealogy research and reading materials. Of tremendous value is access to Library editions of popular genealogy databases such as Ancestry, Findmypast, Fold3, and MyHeritage, along with institutional versions of historical newspaper databases. (Click here to learn more about the differences between the major genealogy websites.) Call your library or browse its website to see what resources may be available with your library card on site or even remotely from your own home or mobile device. And remember to watch for your library’s e-media options like those recommended by Autumn.
As a special shout-out to all the free genealogy resources at your library, Lisa Louise Cooke has granted free access for everyone to Genealogy Gems Premium Podcast episode #125. In this episode, Lisa has a full discussion about more free genealogy gems at public libraries with Cheryl McClellan. Cheryl is not only my awesome mom, she rocks professionally as the Geauga County, Ohio public library system staff genealogist!
This Premium episode is usually exclusively for Genealogy Gems Premium members. If you love it, and you’re not already a member, consider gifting yourself a “back to school” subscription. It’s the most fun, energizing, apply-it-now genealogy learning experience you may ever have.

Family history organizations and studies based on individual surnames have been around for years. They are now integrating YDNA research into their efforts. Use surname projects to enhance your paternal DNA research!
Surnames are the flagships of our genealogical research. We name our files after them and we tag our research with them. We wear our last names proudly on pins and necklaces and T-shirts.
But surnames can also be misleading. Illiteracy, language barriers, and just plain carelessness led to misspellings and alterations, not to mention those ancestors who blatantly changed their name to avoid detection.
The advent of YDNA testing has changed the way many genealogists view surnames and their role in their genealogy. Because a man’s YDNA is the same as the YDNA carried by each of the ancestors in his direct paternal line, the YDNA can act like a filter, clearly indicating which men with a particular surname, or variant, truly share a direct paternal line.
So how has YDNA testing affected family organizations that do surname research? I asked Debbie Kennett, a regular contributor to the International Society of Genetic Genealogy Wiki and Facebook page who is also involved with the Guild of One Name Studies. The Guild of One Name Studies was established in 1979 to promote public understanding of one-name studies and preserve the information obtained by those studies.
“Virtually every common surname is now the subject of a DNA project,” says Debbie, including “just over 500 Guild members who are running a DNA project. That number has jumped up considerably just in the last couple of years.”
The quality of those projects varies. Debbie tells us that a quality YDNA project includes three elements: “presenting the DNA data, recruiting people from different countries and also correlating all of the genealogy information.”
Jean Morrison, a member of the Morrison surname project, says that because of DNA testing, “identifying where in Scotland this family originated prior to coming to America ca 1728 has become a realistic goal. The Morrison Q Group has identified through Y line testing at 111 markers, 22 individuals with an MRCA (most recent common ancestor) within eight generations.” In plain English, this means that a definite YDNA pattern has been associated with her Morrison surname and with a common ancestor eight generations back.
Noel and Ron Taylor were two early adopters of YDNA testing for their Taylor family project. Their first samples were submitted to the Sorenson Molecular Genealogy Foundation in 2000. The former president and currently the head of the board of trustees for the Taylor Family Society, Noel says that using DNA “caught the attention of many people in our organization….It renewed great interest in the hearts of many people who had been doing research for many years [who may have] lost interest and were somewhat discouraged.” The Taylors have made significant breakthroughs with their DNA testing. They have connected several Taylor lines back to a common ancestor, verified their paper trails, and even found a line of Hodges that were actually Taylors!
It appears that YDNA is becoming part of the research plan for most family societies. But Debbie tells us that there is still much room for improvement in her organization. “Not all Guild members are running [DNA] projects. We have something like 2,700 Guild members so we are still not at the stage where the majority of Guild members are running projects.”
Besides The Guild, other organizations have been created to assist genealogists with their surname research, including a new organization just launched in November. The Surname Society’s goal is to “to build a collaborative environment where members are encouraged to develop their own approach to the investigation of their surname.”
Kirsty Grey, chairman of the Surname Society, says that DNA testing has taken a front seat role in the research of one of their founders as well as several early members. “DNA is one of the many strands of family history research (and to a greater extent, surname studies) which can connect individuals, often where genealogical research cannot.”
That really is the bottom line. DNA, especially YDNA, can tell you things about the surnames in your pedigree that you can’t learn in any other way. If you haven’t yet, it’s time to jump on the YDNA bandwagon and see what your DNA has to tell you.
