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 that descends from this couple and I am fairly certain this is our connection. I wanted to see if there were others out there that 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.” (GlobalSearchAdv.png, GlobalSearchJuliaPond.png)
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.
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. Or 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!)
