I recently obtained my Y-DNA 67 marker results from FTDNA and I'm struggling to get up to speed. I've read their getting started info, but it leaves some questions unanswered.

For starters, I have an "exact" match with 0 Genetic Distance, where FTDNA estimates a 90% probability that the match and I share a common ancestor within the last 4 generations. Since this test traces only my direct paternal ancestors, does this suggest that my match and I most likely share either the same father, grandfather, great grandfather, or 2nd great grandfather? If that's an incorrect interpretation, what exactly is this reporting telling me?

Thanks for your help. Have patience with me; there will probably be a few more questions coming.

Yes, your results tell you that you share a direct male ancestor with the man you match with. It can suggest how close the relationship is but not pinpoint the generation. If the match is agreeable, what you need to do now is compare family trees.

By the way, there is the possibility that the match is someone you already know is a cousin.

Thanks, Suzy. That's the only way I could interpret it, but it seemed too specific to be true. That's pretty cool! My only previous experience has been autosomal DNA, so I'm not accustomed to that degree of specificity. My match's full name is included and is not familiar to me, so I'm looking forward to establishing contact with a new cousin. Thanks again, I appreciate your help.

What haplogroup were you assigned? Did you find a match to anyone with your surname? What if you look at your 37 marker matches?

A genetic distance of zero at 67 markers can still be a distant connection, more than 5 generations back, or a more recent one. Have you also taken the Family Finder test? If your Y-DNA match has taken Family Finder, there will be a "FF" in his listing. If you have also taken Family Finder you would be able to tell if he matches you there, and how close the relationship might be. He may have been adopted, or there may be a NPE somewhere in either your line or his (or both).

I think you mentioned you've taken the AncestryDNA test. If you haven't taken Family Finder, and your Y-DNA match has, you can both upload your raw data to GEDmatch to compare autosomal DNA.

I think it's a 90% probability that you share an ancestor within 5 generations: https://www.familytreedna.com/learn/dna-basics/ydna/

95% probability you share a common ancestor within 7 generations.

So the common ancestor could be up to a 5th great grandfather - or even further back but the odds get lower.

Your experience just means the right people to help you have not been tested. That does not mean no one will be able to get past the beginning. The OP already has one close contact.

I am waiting for my Family Tree DNA results. Do you know when you sent your’s in? Mine took forever just to be logged in. Says results should be in between 2/28-3/14. Previously tested with 23 and Me and paternal side showed up. Fascinating because I am adopted. Testing with Family Tree to confirm results with this family member who tested there. Gedmatch has us as half-siblings. Wondering how much longer we need to be in suspense.
How long are these tests with Family Tree taking these days?
