Last fall I talked about getting my DNA analyzed, and upgrading from a 12-marker test to a 37-marker test.
That was completed quite a long time ago, and the results are back. I have no 37-marker matches in the Family Tree DNA database. I think this database contains 67,121 other DNA samples, which is tiny compared to the population of the industrialized world (say, 1 billion+).
Interestingly, I do have 62 12-marker matches, and 3 close 25-marker matches. But it is the 37 marker match that will find someone who is closely related to me, so I am anxiously waiting on the first long-lost relative.
Incidentally, with the 25-marker match, FTdna estimates there is a 62% chance I share a common ancestor with this person within the last 10 generations. 10 generations is a long time - 250 years more or less. My own ancestry is only mapped 4 generations! So who the heck knows if I am related to this person or not. Geez, 250 years ago my ancestors were still in Europe!
