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.

From Joan: “I used one of the handy hints from your presentation at the South Orange County California Genealogical Society’s all day seminar in Mission Viejo, CA. I entered some of my common named ancestors, used the quotes, added a time frame and included some key words, like locations. Most of what I found were my own queries and posts. That shows it works!….
One thing I was amazed at was a multi-page article I found: ‘The Lincoln Kinsman,’ written in 1938. It included a lot of information on the Bush family [which is another of her family lines]. The article even included what I think is my ancestor Hannah Bush Radley.” (Click here or on the image above to see a copy of “The Lincoln Kinsman” at Internet Archive.)

GEM: VICTORIAN SCRAPBOOKING
The Victorians coined the phrase “scrapbooking:” they literally pasted paper scraps into books. As an embellishment, those who could afford to bought “relief scraps,” such as the ones shown here. These were like the precursors of modern sticker sheets or die cuts, printed just for the scrapbooking hobby. You could buy colorful images of everything from flowers or children to animals, or angels or Father Christmas. These images were raised or embossed on the paper, which is why they called them reliefs.
Relief scraps could be used as embellishments around other items on scrapbook pages, but sometimes they were the only decoration on a page, arranged in pretty patterns.
This Ladies Home Journal magazine from May 1891 at HathiTrust Digital Library describes quote “a Sunday Scrap-book?as a source of almost unlimited pleasure and profit to children who can read and write.”

DNA WITH DIAHAN, Your DNA Guide
I don’t think there is any dispute that the four major online resources for genealogy include Ancestry.com, FamilySearch.org, Find My Past, and My Heritage. Of those four, only Ancestry.com has attempted any real integration of DNA test results into traditional genealogy.
That is, until recently. On May 19, 2016 MyHeritage announced that they will be adding a DNA matching service to their offering, and then on November 7th announced they would be conducting DNA tests themselves. Now, MyHeritage has enjoyed partnerships with 23andMe and Family Tree DNA for quite some time now, but those partnerships have been woefully underutilized and are little more than an affiliate service, where MyHeritage provides a discounted rate to test at those companies.
There is no question that the launch of DNA Heritage fully into the genetic genealogy market is exciting news. In fact, it is something I have been pushing for ? we absolutely need someone to challenge AncestryDNA. Competition is good.
In September they began to provide matching results for individuals who had uploaded their results. As of today, uploading your results is still free, so if you have been thinking about it, you may want to take advantage sooner rather than later. As expected, the matches are only as good as the depth of the database, and it is early in the game, so their database is small, but even now we can get an idea of what to expect from MyHeritage as they take their first steps into genetic genealogy.
One of the most exciting elements of their November 7th announcement is their development of a Founder Population project where they have handpicked individuals to represent their reference population for calculating ethnicities. They plan to launch with 25 population groups, but will likely increase to 100 in a fairly short amount of time. This is a far more advanced ethnicity report than is currently offered anywhere else.
After you have figured out how to download your raw data from your testing company (see my instructions here: http://www.yourdnaguide.com/transferring), and then managed to add it to My Heritage (you have to add a family tree to MyHeritage to do this, see further instructions in their May press release), and waited the requisite time to process, you will receive a notice that you have new DNA matches.
For a full review of the features and ins and outs of where to click and what to look at, please refer to the September blog post from MyHeritage.
As for my favorite features, I like how they list all the possible relationships that make sense between you and your match taking into account multiple factors like your age, gender, and your genetics instead of a simple, generic range like 2nd-4th cousins. The accompanying chart that visually shows you all possible relationships is also very helpful. You can access it by clicking on the little question mark icon next to the relationship suggestions. I like that these suggestions remind us that our genetic relationships have different genealogical interpretations. Meaning that genetically, a 2nd cousin once removed, a first cousin twice removed, and a second cousin, all fall within a similar genetic range and it is impossible to determine your exact relationship based on the genetics alone.
I also like that they are providing all three genetic descriptors of your relationship: total amount of shared DNA, how many segments are shared, and the size of the longest piece of shared DNA. While this more of an intermediate to advanced piece of your results, it can be important as your relationship analysis becomes more involved.
One unique claim made by MyHeritage in their press release about their matching feature addresses a main concern that genetic genealogists have: the lack of pedigree information provided by their matches. MyHeritage claims that 95% of their DNA samples have pedigrees attached. That is remarkable! However, from my own quick calculation of my matches, the number with pedigrees is more like 60%.
They also indicated that they will soon be doing a bit of pedigree analysis for you by providing a list of shared surnames and locations between you and your match based on the pedigrees you have both submitted. This will certainly be a welcome addition.
According to the November 9th Q and A they haven’t decided yet if the ethnicity features will be available to those who only transfer, and they hint at many more features they have in the works that may only be offered to those who purchase their test.
In short, the MyHeritage site is currently functioning much like the top three genetic genealogy sites (Ancestry, Family Tree DNA, and 23andMe) and like the free tool Gedmatch, offers a meeting place for those who have been tested at one company to meet those who have tested at another, with the added bonus of a promise of new features on the horizon.
