In this special episode, host and producer Lisa Louise Cooke takes a look at the Golden State killer, one of the most notorious crime sprees in recent memory. She’ll talk about the role that DNA testing played in an ultimate arrest, and the impact that these events are having on genealogists and the use of DNA in genealogy.
Between 1974 and 1986, activities attributed to the Golden State Killer include at least 12 murders, more than 50 rapes, and over 100 burglaries in California from 1974 through 1986. The criminal’s methods led some investigators to believe that these differently-labeled criminals were very likely one in the same. In 2001, DNA definitively linked several rapes in Contra Costa County believed to have been part of the East Area Rapist series, a series of murders in Southern California. In 2011, DNA evidence proved that the Domingo?Sanchez murders were committed by the same man, known as the Golden State Killer.

Trying to contact your DNA matches can be frustrating when they don’t respond, but it’s still worth reaching out to them. This researcher’s example shows a good reason why.
Contact Your DNA Matches
Recently, I heard from Genealogy Gems Premium website member Ruth*, whose DNA success story reminds me of the value of reaching out to DNA matches, even if the general response rate is low or slow. She says:
“I’ve been researching my family tree for over 20 years and sometimes it can get boring…because most of the lines are pretty much out as far as I can go and I’m now just working on brick walls! I love listening to your podcast because it motivates me to keep going!
Like many of your listeners, I have taken the autosomal DNA test. It has been an awesome tool helping me confirm family lines and sometimes finding new ones. However, I’m sure most of your readers know that for some reason a lot of those DNA matches and even tree owners in general, do not respond to emails or messages. It can be very frustrating, especially if it is one of those lines that you really could use some help on. The lack of response to inquiries sometimes makes me wonder if I should even try to make contact. Well, I want to tell your listeners, that yes it is worth it.
Recently, I was browsing trees and I came to a tree that listed my 3rd great-grandfather Daniel Cannon; however, this tree listed Daniel’s wife as Mary Ann Watkins and I had her as Mary Ann Cook! Well, I decided to contact the owner of that tree and explained I had Daniel’s wife as a Cook. The two of us started emailing back and forth and I found out this gentleman, whose last name is Watkins, had taken a DNA test and was in Ancestry.com’s database.
Sure enough, when I searched my mom’s matches I found him. Mr. Watkins shared the information he had [which was] an excerpt that listed the heirs of G. B. Watkins and Elizabeth Smith. On that list was Mary Ann Constable. From the census records, I knew that Mary Ann Cannon had married Thomas Constable after her husband had died. The marriage license for Mary Ann Cannon and Thomas Constable is no longer at the courthouse, but I was able to get a copy of the excerpt of the book it was recorded in. So now I’m climbing a whole different tree!
So, go ahead and reach out to those matches or those people who have trees with different information from you. You never know when you’ll find information and end up with a new line to research!”

Time to Test Your DNA Today
These companies all provide autosomal DNA testing, the most popular kind of DNA testing, and the kind Ruth used. Autosomal testing matches you to genetic relatives on both sides of your family tree to a depth of about 4-6 generations. Learn a little about each by clicking on the names below.
Family Tree DNA (FTDNA) has some of my very favorite genetic tools to help you make connections with your DNA matches when you can’t immediately find a genealogical connection, but it’s no secret that their genealogy tools leave much to be desired. However, their latest genealogy tool has promise: if certain conditions are met, you will be able to see whether any descendant of one of your ancestors has taken a DNA test!
For quite some time now FTDNA has allowed you to enter your genealogical surnames and locations into your account and list your earliest known paternal and maternal line ancestors. The latter is displayed for your YDNA and mtDNA matches to see and the former for your autosomal DNA matches to see. As a bonus, if one of your autosomal matches shares an inputted surname, FTDNA will bold that surname (or location) for you in the “Ancestral Surnames” column of your match page.
A few months ago they upgraded their pedigree tool for uploading a GEDCOM into your account. This GEDCOM does not in any way interact with your DNA match list or results; it is just provided as a resource to your matches. The pedigree tool itself is clumsy at best, but at least it is searchable and can give you a head start when looking for matches. It would be really nice if FTDNA could scrape all the surnames and locations from your GEDCOM and use that to populate your Ancestral Surnames field, but it does not.
The latest addition to FTDNA’s mediocre genealogy offerings is the ability to search all of the uploaded pedigree information in the FTDNA database. The best part about this feature is that it is not limited to searching just your DNA matches. This means you can see if any descendant of one of your ancestors has taken a DNA test! This is great news!
Of course, you see the immediate problem: if the cousin of interest hasn’t uploaded a GEDCOM, you still won’t be able to find them. And, of course, the usefulness of the information is completely dependent on other people’s genealogical sleuthing skills. But still, this can be a useful tool.
I tried using this tool to find out if there were other descendants of my ancestors Julia Pond and Austin Tilton who had tested. I have one DNA match who descends from this couple and I am fairly certain this is our connection. I wanted to see if there were others out there who were also descendants of this couple. I started with just a search for “Julia Pond” and got 37 results. I then used the advanced search feature to add her birth year “1821” and “Ohio.”
There were two matches. My family tree, and another belonging to Katie. It was frustrating that I couldn’t see right away if Katie was also a DNA match. But in the Advanced search I can ask to see only DNA matches, and repeat the search. Katie disappeared. By doing this I learned that Katie is descendant of Julia and Austin, but she and I don’t share enough DNA to be considered related. This makes sense, since descendants of this couple would be my 4th cousins at best, and I know that I will only genetically match about half of my fourth cousins. I can now contact my DNA match that lists Julia and Austin on his pedigree and ask him if Katie shows up on his match list. Perhaps they share some DNA that I do not.
Speaking of that DNA match of mine: why wasn’t he listed in my search results for Julia Pond? Well, it turns out that in his pedigree she is listed as born in 1821 from OH, and my search said Ohio. Ah. The search function is not catching those kinds of differences. So be careful.
When implemented properly, this tool can help you collect all of the descendants of a particular ancestor so you can learn more about what DNA you inherited from whom, and further your genealogical efforts.
Are you ready to get started? If you’re new to genetic genealogy, the first thing to do is acknowledge you may face some unexpected discoveries. If you’re not willing to chance some surprises on your family tree, don’t pursue it yet. Next, evaluate FTDNA (or other DNA companies) for yourself. If you decide to get started, your first step should be to upload your own GEDCOM, and make it public. Don’t feel like you have to put everything you know in this GEDCOM, just what you are certain of and feel confident sharing. To make it public, go into your Account Settings, and agree to share your Basic Profile.
After this Family Tree DNA review, if you’re ready to explore what DNA can do for YOUR genealogy, why not explore how I can help you do it? My quick guides on genetic genealogy include a guide specifically for those who test at Family Tree DNA.
You can also hire me for an individual consultation to make sure you’re doing the right DNA tests with the right relatives to answer your burning genealogy questions. (Testing the wrong people or DNA type can be a very expensive mistake!)
RootsTech 2018 was so exciting—especially for a genetic genealogist such as myself! There were so many DNA lectures to choose from every day, including the one I’ve recommended at the end of this post. (It was so much fun–I did it with Lisa Louise Cooke! And...
