My Family Finder results came in today (over a month earlier than estimated!). I was a little disappointed with my matches, or lack thereof (none were closer than 4th cousin range), but I know the database will only continue to grow. I was pleasantly surprised when I saw my Population Finder pie chart though:
I'm especially impressed that it picked up on the Adriatic connection specifically (represented by the "Romanian" I believe) as my Italian ancestors are from the village of Vieste, which right on the Sea.
For anyone interested in what the Population Finder is and how it is calculated, see here.
Full disclosure: No one but little old me paid for my Family Finder test, nor did I receive remuneration or prompting of any kind from anyone to write this post.
