DNA Matches: What You Can Do with All Your Genetic 4th Cousins

(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. 

what to do with your 4th cousins DNA genetic genealogy

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.
too many 4th cousins DNA matches

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:

  1. Go to http://www.google.com/earth/download/gep/agree.html
  2. Click the blue download button
  3. Read the Terms and Conditions
  4. If you agree to them, click the Agree and Download button
  5. Follow the installation guide
  6. 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:

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 32 couples

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.

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

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.

MAILBOX: Finding a Female Immigrant Ancestor

Question from Jo: “I have been fortunate to find information about most of my great-grandparents.  I have hit a wall with my maternal great grandmother who immigrated from Switzerland to the US in the 1880s when she was 8 years old. I was hoping that by upgrading to International records on Ancestry that I could find the ship and where she and her mother came from. The curious thing for me is that she and her mother traveled solo to the US and went to Cincinnati, Ohio. I’ve been to Cincinnati and have searched there and have found directories with addresses but no profession is listed like other people. I didn’t find any ship records either. Where might you suggest that I look or search to find more information?”

Tips for searching passenger arrival lists:

Consider what ports would have been the most logical point of arrival for an immigrant ancestor based on the time period and the U.S. location in which you find them. Cincinnati, Ohio, was reachable by rail by the 1880s from major ports, as well as by water via the Mississippi River for southern ports, so that doesn’t narrow things down much. According to an Ancestry.com article, more than 80% of immigrants arrived at the Port of New York by the 1890s, so Jo might scrutinize those New York passenger arrival lists for the 1880s again.

Free New York City passenger arrival databases at

Search multiple NYC passenger lists simultaneously at Steve Morse’s One-Step web portal

For “deeper” searching at Ancestry.com or other sites with powerful, flexible search interfaces: do a “nameless search” (without any name) for girls around age 8 for arrivals in particular years. Try additional searches with various combinations of name, place of origin (Switzerland) or “Swiss” in the keyword field, which will bring up that word in the ethnicity or nationality column. That column doesn’t have its own search field in Ancestry.com but it is indexed, so use the keyword field to search it.

Tips for researching records of immigrant societies:

In the U.S., the time between an immigrant’s arrival and naturalization is often documented in records of ethnic organizations such as fraternal benefit societies, immigrant aid and colonization societies. These kinds of community groups often existed in cities and towns where specific immigrant groups had a strong presence.

Tips for researching naturalizations:

Naturalization records from that time period won’t reliably tell you where an ancestor was from. But they’re still worth looking for, especially if census or other records indicated that the person naturalized.

When looking for women’s and children’s naturalization records, remember that during this time period, they automatically became naturalized if their husband or father did, so individual records for married women and minor children won’t exist under their own names. But a woman could apply on her own, too. Click here to read a free article on women’s naturalizations.

DNA WITH DIAHAN SOUTHARD

Parents spend a good portion of their parenting time ferreting out the real story from their children. One time when Henry was in Kindergarten he was playing outside with another little boy. I was in and out of the house watching him and checking on other things. Hours later I noticed that his bike had been spray-painted black. When confronted, he claimed he had no idea how such a thing could have happened. Unfortunately, I jumped to conclusions and blamed the other kid (you have to give me credit, at six Henry was such a good boy and had such an angelic face with his blue blue eyes and blonde blonde hair). But as I was on the phone with my husband telling him about the issue I looked over at Henry and I saw it- that guilty look and my stomach sank, recalling the things I had said to the other boy’s mom. “I’ll have to call you back,” I told my husband.

As genealogists, we spend our time trying to ferret out the real story from our ancestors, or at least from the records they left behind, because they’re not sitting in front of us with guilty looks on their faces. We are constantly checking family stories against, say, the information on a census record, then comparing it to the family will, then making sure it all agrees with what’s in the military records. And even if we have total agreement, which isn’t always, more information often comes along, like in the form of DNA testing, and we may find even more apparent discrepancies.

I recently read an article in the Wall Street Journal about a reporter, Cameron McWhirter, who talks about finding just 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.” And he makes the point that “many immigrants reinvented themselves when they arrived here (the United States),” which could be a nice way of saying they had a chance to INVENT a new legacy, not just reinvent it. His assessments are certainly interesting, and worth reviewing, to help us see how DNA testing can affect the way we look at family stories and traditional research results.

McWhirter may be the classic modern genealogist, never having set foot inside a courthouse or scanned through microfiche, relying instead entirely, he reports, on internet research. Now before you roll your eyes, just stop for a minute and appreciate how exciting this is. Here is a man who never gave his family history a second thought, yet because of the death of his parents started to tinker around a bit, and then due to the large volume of information online “was quickly pulled into the obsessive world of modern genealogical research.” I say, score one for the genealogy world!

What he found was that while his dad was proudly and solidly a self-proclaimed Scot, the records and DNA 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 they flew in the face of his father’s prejudices and assertions of his own identity. But the ethnicity results fall short of the point of testing for most genealogists. He might even more powerfully transform his sense of family identity if he took a look at his match list and saw an actual living cousin, for example, a third cousin perhaps who was also descended from his German great-grandmother, who maybe never mentioned that she was also Jewish.

Connecting with other cousins who also have paper trails to our ancestors serves to provide further confidence that we have put all of the pieces together and honored the right ancestor with a spot on our pedigree chart. It’s like we multiply our own research efforts by finding more people like us?literally?who are descended from the same people and interested in finding them. As long as they’re as diligent in their research as we are, of course.

At a recent conference I met a 5th cousin. Even with a connection that distant it was exciting, and it made we want to look again at our connecting ancestors and pause for just a minute to marvel how my DNA verified my paper trail back to them, and that part of them was around, in me, and in my new cousin. To me, THAT’s a bigger picture I want to see?when the paper trail comes together with the DNA trail and turns into real live cousins, even if they turn out to be a little different than the stories and sense of identity that were handed to us when we were young.

Maybe you’re something like Cameron McWhirter: you’ve taken a DNA test, been intrigued (or disappointed) by the ethnicity results, but haven’t yet fully explored all your matches on your list. I’m telling you, you may be seriously missing some opportunities. If that’s you, I may actually 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 tested. You’ll get an intro to chromosome browsers and their role in the search process, and access to a free bonus template for evaluating the genealogical relationship of a match in relationship to the predicted genetic relationship. This guide also gives you a methodology for converting UNknown relatives on your match list into known relatives, which is what we’re going for here.

So check it out, either as a solo purchase or as part of my Advanced DNA bundle.

Free WWI App from the National Archives

The National Archives is marking the World War I Centennial with a new app, as well as programs and exhibits. Here’s the scoop from their press release:

WWI Free App National ArchivesThe United States declared war on April 6, 1917

Washington, DC – The National Archives marks today’s World War I Centennial with a new mobile app, special programs, featured document displays, traveling exhibits, and a special new webpage highlighting all related resources on National Archives News.

Remembering WWI App

Remembering wwi appToday, the National Archives launches the Remembering WWI interactive app, now available free of charge through iTunes (iPad only) and Google Play. The app commemorates the 100-year anniversary, in April 2017, of the U.S. entry into World War I.

The app provides an unprecedented collection of WWI content digitized and preserved as part of the larger Wartime Films Project – much of it never-before-seen by the public – including photos and film shot by the U.S. Signal Corps from 1914 –1920.

National Archives’ partners for the design and testing of the app included: Historypin, Library of Congress, Smithsonian’s Museum of American History, WWI Centennial Commission, WWI Museum, and, American Association of State and Local History.  This project is made possible in part by an anonymous donor and the National Archives Foundation.

Saving World War I and II Media through Digitization and Crowdsourcing

Thanks to a generous donation from an anonymous donor, the National Archives embarked on a three-year project to digitize and create public engagement with World War I and II motion pictures and photographs. The project’s original goal was to digitize 70 films and 75,000 photos, and foster engagement on the new digital platform, but by the end of the project, the National Archives had digitized 164 films (337 reels) for more than 65 hours’ worth of content, in addition to more than 100,000 photographs. This is the first time that many of these photos and films will be viewed by the public. All scans are available through the National Archives Catalog or on our YouTube page.

Special WWI-related Exhibits

Featured Document Display: Making the World Safe for Democracy: U.S. Enters WWI
East Rotunda Gallery, National Archives Museum, through May 3, 2017

To commemorate this centennial, the National Archives presents a special display of the Joint Resolution declaring war against the Imperial German Government, April 6, 1917. President Woodrow Wilson signed this declaration of war on April 6, 1917, ending America’s neutral stance on the World War conflict and formally declaring war against Germany. The National Archives Museum’s “Featured Document” exhibit is made possible in part by the National Archives Foundation through the generous support of Ford Motor Company Fund.

Traveling Exhibit:  Over Here: Americans at Home in World War I

Over Here: Americans at Home in World War I draws on the unparalleled holdings of the National Archives to capture the patriotic fervor of draft registration, the emotional good-byes of men leaving for training camps, the “hoopla” of Liberty Loan drives, the craze for volunteerism, and the violence of vigilantism.  The exhibit is divided into three themes: Mobilizing the Nation, Stirring Patriotic Passions, and Policing Enemies at Home.  Over Here is organized by the National Archives, and traveled by the National Archives Traveling Exhibits Service (NATES).

Traveling Exhibit:  Over There:  Americans Abroad in World War I

After the United States entered World War I, 1917, millions of American men joined or were drafted into the armed services. Some 2 million served in Europe with the American Expeditionary Forces. Over There: Americans Abroad in World War I showcases World War I overseas military photography from the immense photographic holdings of the National Archives. The exhibition includes photographs from the fronts, behind the lines, and the consequences of the war and how it was remembered.  Over There is organized by the National Archives, and traveled by the National Archives Traveling Exhibits Service (NATES).
