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!)

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!”

Opening your AncestryDNA account to find a New Ancestor Discovery can be a bit like the experience my nine-year old had at the beach today. He noticed something unusual in the sand on his way down to the beach and excitedly used his hands to unearth the treasure. However, it turned out to be a Captain Hook figurine long lost by another (likely much younger) beach-goer. His initial excitement quickly dissipated. He was disappointed as he had clearly found something he did not need or want.
I have heard from many of you that are confused and disappointed with Ancestry’s attempts to merge your genetics and your genealogy. Keep in mind that AncestryDNA matches are only using your genetics. Your DNA Circles and your New Ancestor Discoveries incorporate your linked tree into your genetic test results.
Lisa recently forwarded me a comment from Kate that perfectly illustrates the confusion I’m talking about. “We had DNA done thru Ancestry,” she writes. “The results [have] made me seriously question what they are showing me. I believe they are using my tree to show me results that are more vague than they are revealing. The latest example they show is a person not related by blood. This family is related by name only (my uncle’s spouse).
“My results from Ancestry show that they use my tree to make matches. Just checked the web page for DNA results. They show numerous matches….Three or 4 contacted me because they were convinced they were related by blood when they may have had a remote tree connection. They contacted me because the DNA results showed they were a 3rd or 4th
cousin, when in fact they would only be a 3rd or 4th cousin in my tree.”
I can see why she’s confused. First, let’s review what an AncestryDNA New Ancestor Discovery (NAD) actually IS. NAD’s are based on the DNA Circle idea created by Ancestry. Remember that a DNA circle is when Ancestry can identify a shared genetic AND genealogical connection between three or more people. Using various standards and measures, they name an ancestor as your connection. This is the ancestor I affectionately call our Party Host. This is the ancestor who passed his or her DNA down to all of their descendants, like tickets inviting them to this party in the future. So, everyone who holds a ticket, AND who has honored that party host ancestor by placing their name in their pedigree chart, is listed as a guest in the form of a DNA circle connection. (Click here to read a blog post about this concept.)
The New Ancestor Discoveries just take that one step further. The NAD is an attempt to find ticket holders who have not yet taken that extra step and added that important Party Host ancestor to their family tree. The NAD is like a nudge, inviting us to double check our family tree to see if this particular ancestor might need to be added. It is important to remember that a NAD comes only after a DNA circle has already been formed, and there could have been errors in that formation. So the very first thing you need to do with a NAD is to correspond with circle members and double check that the Party Host of the circle, their common ancestor, is correct. Then we can move on to evaluating the NAD.
Ancestry admits on its help pages that there are three reasons why you might get an NAD, and only one is “right” in the way you and I might view it.
The “right” answer comes when the DNA circle was drawn correctly, the Party Host properly identified, and your DNA connection is strong to two or more members of the circle. You are then able to verify through traditional genealogical methods that you are an actual descendant of the Party Host, holding that coveted ticket, shown in blue in this modified image from the AncestryDNA help page.
There are two other alternatives.
First, you are related to the NAD Party Host (the New Ancestor that was discovered) via marriage. In this second example from Ancestry’s help page, we see that your ancestor was married twice. The members of the DNA circle are descendants of her other marriage. Remember, that you do not share DNA with every member of the DNA circle. In this case, you share the purple DNA with a few members of the circle. But there are other members that share the blue. So the super computers at Ancestry first put all the blues together in a circle with the Party Host at the top. Then you come along with purple DNA that matches a few in the circle and their supercomputer erroneously assumes that you too must have been invited to this “blue” party, but in fact, the blue/purple members of the circle are double booked. They have been invited to both the blue and the purple party.
How can you fix this? If you can identify your purple Party Host, then you can add that person to your tree, and the trees of your DNA matches and likely then a new DNA Circle will form with the purple Party Host at its head, and the blue NAD will disappear.
The other situation that many of you are seeing, especially those of you with ancestry from small communities, is demonstrated in Figure 3 of the Ancestry Help page, reproduced here. As you can see, this one is much more complicated. (In fact, the colors I added aren’t even quite accurate, as not all descendants of the blue NAD have the same blue, but rather different shades of blue depending on the segment they received- but this is a story for another post!)
The short of it is, the members of the previously established DNA circle share one single ancestor with each other, but they share multiple separate and distinct ancestors with you. Looking at this chart it seems very clear, but remember, in the database we only see you and the people you match. We cannot tell from the DNA shared which piece came from which ancestor. So, it is very important to check and double check the pedigrees of those in the circle to identify additional shared lines.
The short of it is, these NAD’s are following the guilt by association rule, but in fact, you could be innocent. Just keep in mind the simple principle that you DO share a common ancestor with those members of the circle that you share DNA with. You do NOT necessarily share common ancestry with those in the circle that you do not share DNA with.
The key is to take these NAD’s for what they really are: research suggestions. Keep your expectations low, and then you will be pleasantly surprised when you are able to verify a connection.

by Lisa Cooke | Jun 17, 2017 | 01 What's New, Adoption, DNA |
DNA testing for adoptees (and others with unknown parentage) isn’t a last resort–use it along with other strategies to discover biological roots. Genetic genealogists CeCe Moore and Diahan Southard share five tips for getting started.
Not long ago, I chatted with genetic genealogist CeCe Moore of The DNA Detectives about using DNA testing for adoptees. Here I summarize some tips she shared, along with some perspectives of my own and resources that can help your search for biological relatives.
Click here to listen to our chat:
DNA testing for adoptees: 5 tips
1. Start with available records. A lot of people of people are coming straight to DNA testing now without looking at any available records first. Adoptees should start by looking at state laws and seeing if they can get access to original birth certificates. Click here to read about access to adoption records (U.S.).
2. Take an autosomal DNA test. This test looks at both sides of a person’s biological family, mom and dad. Most people start by testing at AncestryDNA because it has the largest database of potential matches (over 4 million now!). If you don’t find a close match (at least a second cousin), you will want to transfer to both Family Tree DNA and MyHeritage for FREE to expand your search radius. Males with unknown paternity should also take a YDNA test (at least at the 37-marker level) from Family Tree DNA.
3. Do your own adoption search. Sure, you can hire someone to help. But you should be invested in your own search when possible. You’ll likely get a much greater satisfaction out of it.
As with any kind of search you are doing for people who may still be living, proceed with care and try to keep your search as private as possible. Try first to contact the people who are most likely to know about you already, including your parents and grandparents. If you do discover a biological family buy ed medication member who may not know about you, please carefully consider the impact you may have on their lives by revealing information you have learned.
4. Become educated. Learn all the strategies you can for researching your biological roots. Read and read! Keep learning! The DNA Detectives Facebook group is about self-education, with members helping members work their own cases without a professional having to work each one. (You can also check out The DNA Detectives website.)
5. Keep your expectations flexible. CeCe Moore says, “The end result of an adoption search is positive most of the time. There are some stories where contact has been rejected by a birth relative, but they are in the minority. A positive outcome doesn’t necessarily mean a connection ora loving relationship with a birth parent, but perhaps with a birth sibling or cousin.”
Finally, I want to share this powerful statement from CeCe Moore on adoptee rights:
“I believe everyone has an equal right to learn about their heritage. There’s a whole class of people denied the joyful experience of building their biological family trees. Everyone deserves that knowledge. That doesn’t mean the birth family has to have a relationship. There’s a difference between knowing your heritage and having a relationship with the birth family. The adoptee deserves the knowledge of their origins.
But you can’t legislate a person to have a relationship with another person!”

If you’re doing DNA tests for family history, you may see lots of predicted cousin matches: 2nd, 3rd, 4th, etc…..But what does that predicted genetic relationship actually mean? Learn about centimorgans, the powerful genetic genealogy unit of measure, and how it helps your research.
How DNA Tests Measure Genetic Relationships
When we are looking at genetic relationships, there are also many ways we can measure them. But ultimately, we want the testing company to tell us how likely it is that a particular individual shares a single, recent common ancestor with us. One factor in this calculation is to take into account the total amount of DNA we share with that match.
Currently, all the testing companies are reporting this sum in centimorgans (cMs). Every company reports to you the total number of shared cMs, as outlined below.
AncestryDNA: Click on the match to access the personal profile page for that match. In the second section, under Predicted Relationship, you will see the confidence level. To the right of the confidence level, you will see a grey circle with a little “i” in it. Clicking there will show you the total amount of shared cMs as well as how many pieces of DNA you share.- Family Tree DNA: On the main match page for your Family Finder results, you will see the total amount of shared cMs in the third column.
- 23andMe: You can see the percentage of shared DNA from the main DNA Relatives home page. To convert the percentage into centimorgans, just multiply your percentage by 68 (that will at least get you close). You can also see total shared cMs in the chromosome browser tool (go to Tools > DNA Relatives > DNA).
- MyHeritageDNA: The total amount of shared DNA is shown on the main match page under the title Match Quality. MyHeritage also has a new DNA Match Review page. Click here to read more about that.
Centimorgan: A Genetic “Crystal Ball”
It is very tempting to think of a cM just like you would think of an inch or a centimeter, and for all practical purposes, that is okay. But it is actually much more complicated than that.
A cM is actually more like a crystal ball: it helps us predict how likely a piece of DNA looks exactly as it did a generation ago. This, in turn, helps us calculate how far back we should be looking for the common ancestor between two people.
But for our practical purposes, you can use the total amount of shared DNA, in combination with this chart compiled by Blaine Bettinger and the Shared cM Project, to better assess your genealogical relationship with your match based on your genetics.
To use the chart, take the total amount of shared DNA you have with a match, and look up that number in the chart to get an idea of what kind of genealogical relationship might best fit the genetics that you see. For example, if I share 69 cM with my match, we might be third cousins. But we might also be second cousins once or twice removed.
How do you figure out which one? Simply put: do genealogy research! It’s time to use traditional records and research skills to better understand the genetic clues in your family history mysteries.
My series of DNA quick reference guides can help you get the most out of your DNA tests for family history. I definitely recommend the value-priced bundle of all 10 guides. But I especially recommend the guides listed below if you’re to the point where you’re trying to understand what genetic relationships mean:
