I have just received the results of my own FamilyFinder DNA test at FamilyTree DNA. I had quite a few matches and several of them have already led to the discovery of new cousins, particularly among the Gabbard-Baker-Smith-Bowman families that lived in several Kentucky coutines - Madison, Clay, Owsley, Jackson, etc. Some of new cousins are related in two or more ways.
Then there are those intriguing matches which don't seem to match - some of these are at the 3rd cousin level which suggests we share great, great grandparents ....but we can't find any surnames at all in common, much less great, great grandparents. One really starts to wonder what some of our ancestors were up to!
At any rate, I've been busy all day, comparing notes and discovering new information and new friends. The above families in Kentucky were all quite far back and I've not included them on my webpage in the past, but after today, I will be doing just that.
I don't pretend to understand all the ramifications of the results of the test, but I do know this: my DNA is "out there" for comparison. I have also ordered a mtDNA test because I can only go back five generations on my direct female line to a lady named Mary Rowena Hoskins. She seemingly had no family, but I'd really like to find one for her.
I wish I had a crystal ball and could see what the future holds regarding DNA studies.
