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.

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:

  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.

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.

Google’s Plus Sign Now Has New Meaning – Search Operators

On October 27 I reported on this blog that Google quietly eliminated the use of the plus sign operator in Google Search. (A Change You Need to Know About


The technology community suspected that “the move was in response to their growing focus on Google+ and the possibility of a new use for the “plus” sign.” I encouraged you to stay tuned.


You didn’t have to wait long to find out why the change was made.  Yesterday Google announced on the Official Google Blog a use for that plus sign: Direct Connect from Google Search.


Direct Connect from Google Search
It’s no surprise that the plus sign’s new role has something to do with connecting users to Google+, the (fairly) new social networking platform. The + sign is now all about quickly connecting you directly to business Google+ Pages.


Many have wondered why Google+ didn’t allow for business and organization profiles since that is a big part of the Facebook offering.  It appears now that the delay was in order to re-purpose the plus sign.


Google explained it this way: “Maybe you’re watching a movie trailer, or you just heard that your favorite band is coming to town.  In buy pain medication online net both cases you want to connect with them right now, and Direct Connect makes it easy – even automatic.  Just go to Google and search for [+], followed by the page you’re interested in (like +Angry Birds). We’ll take you to their Google+ page, and if you want, we’ll add them to your circles.”


So the plus sign can now get us connected to Angry Birds, quicker?  Whoo hoo?! Gosh, I was perfectly happy with the way the plus sign got me to web pages that shared information about my ancestor (+Jehu Burkhart I miss you!)


Direct Connect is up and running for a couple of the big boy brands like +Google, +Pepsi, and +Toyota, so you can try those searches to see how they work.  Eventually the rest of the world will be allowed in and you can learn more about how Direct Connect for your organization in the Google Help Center. 


So remember, if you want to connect with Pepsi you can plus. But, if you’re looking for a specific ancestor, word, or phrase you need to surround them in quotation marksAnd you can quote me on that!

You don’t have to love genealogy to put these tips into action! So join me as I share a little tech-tip on how to use Google image search to identify old photos on smartphone and tablets.

how to use Google image search to identify old photos

My new tech-tip video posted to the Genealogy Gems YouTube channel is all about how to use Google image search to identify old photos. You may remember, I posted a similar video on how to upload an image to Google on your laptop or home computer, run a search to find other images that match, and most importantly, identify that image. After watching that video, Doris wrote me the following email:

“I just enjoyed your video about Google Images. It seems that it won’t work on my iPhone 6S +. I have to wait until I am on my laptop, later. What a great tip! Thanks for all you do to help us make our computer life easier and more fun.”

Well Doris, you don’t have to wait to get back home to do a Google image search! This video will show you, step-by-step, how to search for images right from your mobile device.

After watching this helpful video, Amie, our Content Creator here at Genealogy Gems, shared with me this tidbit:

“Lisa, I just wanted to share what I did after watching your video, “How to Google Search Images – Smartphone and Tablets.” When I had a little wait time, I went into my FamilySearch app on my phone and found the pictures I had saved to my FamilySearch Tree. Then, using your instructions, I looked to see if any of those ancestor photos were found anywhere else on the web. Guess what? I made a cousin connection with one of the photos. I found a cousin had put Great-Grandpa’s picture on her Pinterest page! Just another genealogy success story!”

And there you have it! By learning a few tips, you can use your smartphone or tablet for searching Google images just like Doris and Amie. A follow-up email from Doris after watching this video just made my day:

“I watched this video yesterday while I was riding in the car. What a fun surprise! I tried it and it worked! Thanks for doing this for me. I am grinning right now just thinking about it.”

You are so welcome, Doris. I hope that others will give it a try, too.

Thanks for watching and reading, friends…and keep the comments and emails coming. I love to hear from you!
