This had both some things I predicted and some surprises. I knew I had some strong Irish, English, and Italian ancestry. My Grandma's side is half Croatian so that wasn't a surprise plus my Great Grandmother's German (though looking through the report it's likely she wasn't 100% ethnically German and just didn't know it...she never did know her father so that's not a shock.)
Now, I suspected that I had some non-European ancestry in me I just didn't know from where. Well, it looks like I have a little African (north and east). Finnish and Iberian were a complete surprise. Pretty neat.
There's another more detailed report that gives you a more detailed breakdown that adds trace amounts of the Middle East and West African to the mix.
