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 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.

World’s Oldest Message in a Bottle: Why Not Make Your Own?

world oldest message in a bottleMSN recently reported the surfacing of perhaps the oldest known message in a bottle. If YOU sent one, what would it say? Warning: craft idea ahead!

British scientist George Parker Bidder set afloat a flotilla of 1,000 bottles in 1906. According to MSN, the vessels were “designed to float above the sea floor in attempts to study ocean currents. All of the bottles contained a postcard that listed instructions in English, German and Dutch to return the note to the Marine Biological Association in Plymouth, England, in exchange for a shilling. When most of the bottles–not all–were found a few months later, Bidder was able to confirm his theory that the deep sea current flowed west in the North Sea, a body of water that borders Great Britain, Scandinavia, the Netherlands, Belgium and France.”

Then recently, a newly-discovered bottle came ashore on the beaches of Amrum, a German island in the North Sea. The woman who recovered it did get her shilling–which had to be purchased from eBay.

My Message in a Bottle Experience
A few months ago, I discovered for myself that the tradition of sending out messages in bottles was still alive. While participating in a local Lake Erie beach cleanup near my home on the east side of Cleveland, a member of our group discovered a bottle. Someone buy medicine online japan gave it to me. Inside were several letters written fairly recently. As I scanned them, I gradually realized they were all love letters to a baby who had passed away. We gently put the letters back in the bottle and the bottle back in the water. But I haven’t forgotten it.

Does the idea of sending a message in a bottle appeal to you?
It doesn’t have to be a pain-filled message cast on the waters, though that might be a therapeutic way to say goodbye or “I miss you” to loved ones. Another option is a happy letter, placed in a cute bottle and given right to a loved one (I suppose you could float it in their sink at home!).

I found this cute how-to craft on YouTube that could inspire YOUR message in a bottle. What would you say? To whom would you send it? Where would you launch it, and how would you hope it would be found?

Emails from Genealogy Gems Podcast listeners.

Frank recently wrote in saying that he listened to Genealogy Gems Podcast episode 227 and my conversation with Ran Snir, MyHeritage DNA Product Manager about their genetic genealogy tools The Theory of Family Relativity™  and AutoClusters. This got him thinking about his own test results and a frustration he has had trying to find matches and records in pursuit of this Galician roots. 

Frank writes:

“Ancestry’s records are almost non-existent, except for some parish records, but this is the region from which Cuba and Argentina were populated, and the ultimate ancestry of Cubans in the US. I have done the AncestryDNA test but my matches are few and far between.

On the other hand, I have worked with a Spanish genealogist and have some records that go back to the 17th century. Is there any program like Ancestry,  23andme, or My Heritage, that can do Galician (Spanish) genealogy well.”

Regarding DNA matches and testing pools:

DNA companies test all types of people and because testers can download their results and upload them to other companies, their pools of people are becoming more similar. Generally, they don’t focus on particular groups. They just report the results based on the pool they currently have. 

Regarding genealogy records:

Start with the FamilySearch Wiki page on Galicia includes links to records within each province.

From Linda:

“I am a regular listener to your podcasts.  And I am the family historian.  I recently received a trove of documents from my Uncle who had been working to chart the family for 25 years.  He passed away last year.  His most recent quest was to find as many old family pictures as possible and I have continued to reach out to distant relatives.  I enjoyed the recent podcast about the New York photographer website and hope it will help me identify people in some of these very old pictures. 

(Episode 236Interview with David Lowe, Specialist for the Photography Collection at the New York Public Library on a free tool they provide that can help you identify your old photos. Also a discussion of how to find unindexed records at Ancestry.com.)

My question:  a friend of mine has inherited all of her family’s old family pictures.  The pictures are from the late 1800’s.  She doesn’t know who most of the people are.  She is not interested in learning and apparently there aren’t any members of the family who have taken the role of family historian.  Is there anything to do with these pictures other than to dispose of them?  It makes me sad to know that no one is interested.  When I learned a branch of my family tree had tossed all of their old family pictures, I felt awful and it has taken me some time to accept that I might not ever find replacements for this branch.”

There are ways to make real progress identifying photos. I’m going to be covering more of this on upcoming episodes. I would start by asking your friend to write down states / counties / towns where she thinks her family lived, as well as her direct ancestors as far as she knows (even if it’s just grandparents or great grandparents.) With some basic genealogical info on the most recent members of the family and some possible locations, you could then post at least some of the photos on Deadfred.com.

This is a site where people search on families and locations and other identifying information to find unidentified photos of their family members. Many, many photos have made their way to family historians through DeadFred. 

If you don’t have time to post them on DeadFred, and you do know the county where some of the photos came from, you could offer to donate them to the local genealogical society. They might be willing to take them, and their volunteers might be willing to do it. 

I agree with you, it would be such a shame to toss them because you can be sure there is someone out there who would treasure them and may even hold answers.

GEM: The Love Letter

Kathleen Ackerman graduated from Brigham Young University with a Bachelor of General Studies: Family History degree in April 2012. She now has her own research company, Finding Ties that Bind. She is also working on a Master’s Degree in Genealogy, Paleography and Heraldry from the University of Strathclyde in Scotland.

Kathleen is the director for the Cave Creek Arizona Family History Center.  She loves to help others as they learn about their family history. For seven years, she served as the Treasurer and British Institute Director for the International Society for British Genealogy and Family History.  Besides her volunteer and school work, she spends most of her free time either working on her husband’s English and Scottish lines or playing with her granddaughter.

“In 2010, my mother found three pages of a letter addressed to “Mamie” among my grandparent’s things. My grandmother has passed away and my grandfather did not remember who Mamie was or why they had the letter. My mom sent me the letter in hopes that I could figure it out.”

 The last page which may have contained the writer’s signature was missing. This is where Kathleen’s search began.

Kathleen turned to census records from the time period, and Google Maps to verify where Medicine Lodge was in comparison to Small, Idaho, the place from which the letter was sent. No such town could be found.

She then turned to old maps to see if the town had once existed. She used maps on the David Rumsey Historical Map Collection website. She found a map of Idaho from 1909, that showed Small, Medicine Lodge river and Reno (all mentioned in letter). They were all in Fremont County, Idaho. Her confidence that she had the right person grew.

The search moved on into vital records. A marriage certificate for Mamie and William Patelzick in Dec 1910 was located.Perhaps they had eloped?

Spoiler Alert: If you haven’t listened to the episode yet. The next image reveals the writer of the letter.

Later, Kathleen’s mother surprisingly found the final page of the letter:
