(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.
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.
More Genetic Genealogy and Google Earth Gems
If you are new to using Google Earth, I have several suggested resources for you by Lisa Louise Cooke:
If you are a Genealogy Gems Premium member, Tune in to Genealogy Gems Premium podcast, episode 131, for tips on how to run a more thorough genetic evaluation on those 4th cousin matches.
Here’s a video of the authors discussing three common DNA misconceptions:
Using Google Books for genealogy is a successful tool to many. A Gem’s reader shares the remarkable story she uncovered using the tips for using Google Books she learned from a recent Genealogy Gems Premium podcast.
From Genealogy Gems Premium member:
“Hi Lisa,
I was just listening to the newest Premium podcast concerning filtering the lists on Google Books (Premium episode 137). I would like to relay my story for using your hints and tips on Google.
My great-grandfather was a Confederate soldier. At the age of 48, he married my great-grandmother and my grandmother was born the next year. I found much to my dismay, that he committed suicide when my grandmother was a few weeks old. It was stated that he had what would be described today as post-traumatic stress disorder, and the burning of the court house where he worked as a county clerk set off something. My Dad was born on what would have been my great-grandfather’s 90th birthday.
I have known for about 30 years that my great-grandfather wrote articles under a pen name. My aunt told me she had been told he wrote articles about the scenery in southern Utah where he lived. I searched and searched and never found any of his articles. Then, I had a breakthrough. I found the pen name by using several tips you mentioned for using Google. The pen name was Lock Melone. It was spelled differently than I had been told.
It turns out, he was a very well-known humorist. One of his stories appears in a publication alongside an article by Mark Twain. (He wrote articles in the 1870s and 1880s.)
Now, back to your tips on Google. I was Googling, checking all the old newspapers I could find to collect his writings. One of the sources continually mentioned in Google Books was a literary magazine called The Californian. These were not all free on Google, but I was not to be deterred after all these years! I used the basic information and time frames listed in Google Books and looked at WorldCat. That led me to e-books and to some of the holdings in universities around the country.
As of today, I have found 69 of his articles! They have made an ancestor who I thought had a rough life with a tragic end, a new person, full of life and laughter! I am sure his stories are based on events that occurred during his “real life” adventures. He lived life to the fullest, traveling a great deal, and saw the world through a light heart.
I am continuing to search for more articles and have begun to compile his writings to give to my children and cousins for a Christmas present this year (if I can figure out how to put it all together!) With my grandmother as his only child, I will have given his life to all his descendants, a very special chore on which I have worked on with great pleasure.
Thanks for the tips on Google and other sites you have given over the years.”
This Gems member is certainly on the right track in many ways. She figured out how to harness the power of Google to search for the proverbial needle in a haystack—not just her grandfather’s articles but articles written under a pseudonym! Good for her for using Google Books and WorldCat. That’s a great combination. You can learn more about using WorldCat for genealogy in my book How to Find Your Family History in Newspapersand in the Premium video Getting the Scoop Part 2: Tech Tools for Newspapers.
Follow-up Ideas for Using Google Books for Genealogy
Here are a few follow-up suggestions relating to finding issues of a literary magazine or another scholarly publication like The Californian:
First, turn to another powerful free tool in the Google toolbox: Google Scholar. It takes Google Books to the next level and you may hit on some things that Google Books may miss. Refer back to Premium Podcast 136 for a discussion of Google Scholar for genealogy, and Chapter 11 in my book The Genealogist’s Google Toolbox, Second Edition.
Second, remember that sometimes serial publications change names, or two different ones may have the same name. Wikipedia’s not the most expert source, but its article on The Californian says something you can follow up on. The Californian was published from 1880 to 1882, as a continuation of the earlier Overland Monthly which had stopped in 1875, and then in 1882 it switched back to its old name. This means you should look for both titles.
A third idea may be to check e-bay for back issues of old magazines and journals. Sometimes, it’s cheaper and easier to buy them than to try to borrow them through inter-library loan. E-bay does happen to have a CD version for sale of The Californian issues from 1880 to 1882. I talk more about finding family history items on e-bay in the Premium Podcast episodes 16, 76, and 131.
Lastly, don’t forget JSTOR. JSTOR is a shared digital library for scholarly journals and the like. It launched in 1995 to serve university and college libraries, running out of space to store old journal issues. Today, it includes over 2,300 journals and thousands of other materials. It’s even started including books. Over 50 million pages are digitized, with another 3 million being added every year.
The nice thing about JSTOR is that you don’t have to be affiliated with a major library to get access now. Individuals can register for free access allowing them to read some materials online. They offer free access to their Early Journal Content collection of scholarly content published before 1923 in the U.S. (and before 1870 in other parts of the world.) That collection alone has nearly a half million articles from over 200 journals.
Unfortunately in this case, JSTOR doesn’t have The Californian or Overland Monthly in its collections. But one can certainly use JSTOR to search for other journals. JSTOR is just a great resource for anyone to use when searching for historical articles, especially those you may come across in Google Scholar without the full article text.

On the results page look for the filter menu. If you don’t see it, click the Tools
Click the down arrow for Any View
Click Full View
Now your results list only include free fully digitized materials.
If you haven’t been over to Google books for a while, this is going to look a little bit different. A while back they launched a new user interface. They’ve now made some improvements. The main difference is we’re going to see this menu along the bottom of the screen.
My favorite new feature: convert image to text
Before we even look at the new menu, I promised you my favorite item that they have added to Google Books.
In the upper left corner, click the three vertical dots icon. This reveals a menu that gives you access to a lot of items that typically are kind of ‘behind’ the book. If you were to close this book, you would see the catalog entry for it.
New menu at Google Books
My favorite new feature here is View as Plain Text. Click the toggle button to convert the entire book to plain text. This makes the digitized images of the pages usable in many other projects and programs. Google applied optical character recognition to the books to be able to read the words on the images to make the books keyword searchable. In the past, we had to use the clipper tool to capture a bit of the image and convert it to text. The box was really small and inconvenient. This new feature provides the ability to instantly use as much of the text as you want.
Convert digitized books to text in Google Books
Because this book is fully digitized, it’s already been cleared for copyright. These books are in the public domain. They are available to use for free, copyright free. You are free to copy the text and include it in your projects, in your genealogy database, in a family history book, and so on.
Download a book
Back over at the three-dot menu in Google Books, you can also:
download the book as a PDF or EPUB for free,
find the book in a store, if you need a hard copy
find the book in a library at WorldCat.
Keyboard Shortcuts Hot Keys
Another new feature is keyboard shortcuts.
Google Books shortcuts / hot keys
Find Book Catalog Entry
I mentioned that the catalog entry for this book is sort of ‘behind’ the book. To access that, click the X in the upper right corner of the screen. This removes the view of the book. We haven’t lost access to the book. You can still access it by clicking the blue Read free of charge button.
The nice thing about the book catalog entry page is that it contains all the details about the book such as where you can purchase it, finding copies at the library, and additional editions.
Source Citation Tool at Google Books
Also on the catalog entry page is the Source Citation tool. Click create citation to reveal the options. Click the desired style, and then copy the citation and paste it in your family tree database, or other places where you are referencing this book. So, there’s no reason not to cite your source for any book found at Google Books. Source citation is very important, because down the road you might discover something more about your family and realize that you need to access that book again. Without the source citation you may not remember where you got the original information. The source citation is your breadcrumb trail back to the previous research that you’ve done. Also, if anybody ever has a question about what you have put in your family tree, you can point them to the sources that you used.
New Google Books Menu
The final new feature at Google Books that I wanted to draw your attention to is the main menu for this item. It used to be at the top of the screen, but now you’ll find it at the bottom. At the top of the screen, we now have a search box that allows you to search the entire Google Books collection. But oftentimes, when you’re looking at a book, you’re going to want to be able to search for particular names, places, dates, events, topics. You will find the search field for that in the new menu at the bottom of the screen. Type in names or other words and press enter. You’ll be given all of the pages in the book that mention those words. Also, in this menu are:
zoom buttons,
chapters menu (if available for the book you are viewing)
page views (single, side by side or thumbnails.)
Clip and download an image from a book
Also in the new menu is the clipper tool. The materials in Google Books contain maps, drawings, photos and many other types of imagery that you may want a copy of. Or perhaps you just want an image of a section of text. The clipper tool allows you to capture it and save it to your computer as an image file.
Click the scissors icon, and your mouse cursor will turn into a clipper.
Draw a box around the desired area
In the pop-up box click to copy the link to the clipped image.
Open a new web browser tab and paste the link. (You can also paste the link into notes in your family tree, and other programs and documents.)
Press enter and the image will appear in the browser tab.
Right-click on the image.
Select Save Image As to save it to your computer’s hard drive.
There you have it, some of the exciting new features over at Google Books. There’s never been a better time to search for information about your family history in Google Books.
