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

by | 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:

  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.

Passenger Lists Records:
Elevenses with Lisa Episode 34

Video & Show Notes
Original air date: 11/19/20

If you’ve ever struggled to find a passenger list or figure out what it’s telling you about your family history, you’re in the right place. In this episode I’ll show you where to look, and how to interpret what you find. Click to watch the video and follow along with the notes below:

A Question About Passenger Lists

Genealogy Gems Premium Member and Elevenses with Lisa viewer Deborah Huber wrote in about some challenges she was having with passenger lists. 

“Hi  Lisa,  I have a few questions about the passenger records I have found for my mother and grandparents.  They are all from Ancestry.com.” Let’s go through Deborah’s questions  step-by-step.

Deborah is looking for the Felberg Family:

  • Otto age 33 (Grandfather) b. 1894
  • Marta age 23 (Grandmother) b. 1904
  • Ruth age 3 (Mother) b. 1924
  • They Sailed March 25, 1927 from Hamburg Germany to New York

“My mother was born in Heinrichshoff on “Stork Day,”  a day celebrating the return of the storks in the spring and welcoming them to their nests on top of the chimneys.”   

Passenger List records to look for:

  • German Passenger list (the outbound record)
  • New York Passenger lists (the incoming record)

Searching for the New York Passenger List

How to search for passenger lists at Ancestry: Search > Immigration & Travel > Search by name and birthdate. If you don’t see both expected passenger lists (ex. Hamburg and New York) check the Card Catalog. Example search: Hamburg passenger or Germany passenger. From the results page you might have the opportunity to click through and see a photo of the ship. You may also find a link to additional passenger lists (in this case, the Hamburg Passenger List).

Question: “Also, my mother always said that they didn’t go through Ellis Island but did land in NY City.  I think Castle Gardens was already closed in 1927 so I’m trying to figure out where they did land.”
Answer: The record collection title alerts us to what is included in the passenger list collection: New York, Passenger and Crew Lists (including Castle Garden and Ellis Island), 1820-1957

A quick Google search will tell us the dates that Castle Garden was in operation: “From August 3, 1855 to April 18, 1890, Castle Garden was America’s first official immigration center, a pioneering collaboration of New York State and New York City.”

Tip: Search Multiple Sources for Passenger Lists
You may find the quality of the digitized image varies from one genealogy website to the next.

Tip: Finding Passengers When Names are Hard to Read
When names are difficult to read, focus on other information that is easier to spot such as the person’s age. In the Felberg family’s case, Ruth was 3 years old. Looking for a “3” in the age column proved much easier than reading the names.

Identifying the Location Named in a Passenger List

Question: On the screenshot from the Hamburg list is says the destination was “Greenlake”.  Is that a port?  All I could find on the internet about Greenlake is that it is a NY state park.  
Answer: The “Greenlake” mentioned in the indexed passenger list record refers to the final destination, not the port of arrival. Carefully review both original passenger list records.

Tip: Don’t Miss Page 2
Like many genealogical records, passenger lists records may be more than one page. If the index refers to something that you do not see when you click through to the original record, it is a strong indication that there is another page. Always look at the pages before and after any digitized record. In this case, we find Greenlake, WI on page 2!

  • 1820 – 1907: Ship manifests are 1 page in length
  • After 1907: Manifests are 2 pages with additional information provided.

Source: The Statue of Liberty – Ellis Island Foundation, Inc.

Now that we know that Greenlake is Greenlake, Wisconsin, we can run a quick Google search to find the correct name and county: Green Lake, Wisconsin. Then continue your googling to find more historical information such as old maps and postcards. Click “Images” on the results page to quickly review the results.

Here are a few of the resources we found for Green Lake, WI:

Hamburg Passenger Lists

Question: “I can’t read the actual document which is the Hamburg Passenger List.”
Answer: The Hamburg passenger list can be found in the Card Catalog. Card Catalog > Search Title (Hamburg Passenger Lists)
2 results: the passenger lists and the index.

We discovered that not only was the passenger list extremely difficult to read due to the ink copying over the page, but also the link did not go to the correct page. This is where the Index, found through the Card Catalog, because indispensable.

Index: Hamburg Passenger Lists, Handwritten Indexes, 1855-1934

  • 1925-1934 (The Felberg’s arrived in 1927)
  • Band 161 (1927 F-J) (The year of their arrival and “F” for Felberg)
  • F (for Felberg)

Search the Index to locate the page number for the passenger’s record. Then go back to the original record and find the handwritten page number in the upper corner.

Tip: Quickly Navigate the Ancestry Record

Simply press the appropriate key on your computer keyboard to quickly navigate the pages.
“N” = Next page
“P” = Previous page
Visit Elevenses with Lisa Episode 17 for more Ancestry search tips and tricks.

We found the Felberg family on page 117, exactly where the index said they would be. It’s a good idea to search all the passengers for others with the same last name. In this case, Otto’s brother Rudolph Felberg was also on the ship. This aligned with the family lore that Rudolph may have sponsored the family’s move.
