Ethnically, as ancestry categorizes things, I am:
61% Europe West
30% Ireland
2% Great Britain
2% Iberian Peninsula
2% Scandanavia
1% Europe East
<1% Italy/Greece
<1% Finland/Northwest Russia
That's all interesting enough, imo. More Irish DNA in me than I expected, but not a big surprise.
Europe West is a crazy mix of everything. I can't blame them for not trying to break it down more. The relatively little I know of European history has so much movement that I can't imagine where you'd find any "pure" DNA.
What really got me going was the DNA matches. You are told who else that's taken the test there is a relative. You need a certain amount of matching DNA to be sure of a relationship of any sort, as opposed to coincidental matches of small lengths. You find people from all over, even around the world, who are related, if only because of a common set of great great great great great great grandparents.

What surprised me the most was all the Dutch ancestors I have. Again, no huge surprise, since I'm from New York. It used to be New Amsterdam, eh? Further, I'm from the Hudson Valley. Hudson was sailing for the Dutch East India Company when he sailed up the Hudson River in 1609. And my mother's mother's maiden name was Hagues. Turns out they had been in England for at least a few generations before coming the the US, so not totally Dutch, by any means.
But my father's side was a real surprise. I've learned a lot of names, and history of the area because of them. A boat called De Bonte Koe (The Spotted Cow) sailed from Amsterdam to New Amsterdam at least a couple times. The voyage in 1663 brought a couple families I'm descended from.
One went to Harlem, which was originally named Nieuw Haarlem - New Harlem - after the Dutch city of Haarlem. The other family went to Long Island, then Bergen County, New Jersey. Several generations later, in 1863, the two families joined when one of my sets of great great grandparents got married.
Also on my father's side is a real long story, finally resolved. My father never met his father, and my father changed his name to Kniffin because that was the last name of his mother and much older siblings. Her husband/their father died fifteen years before my father was born, and he did not know about any of it until he was about 11. We've always known the name on my father's birth certificate, but couldn't be entirely sure. But we've long heard that there was another son by this same man. My wife found this half-uncle of mine on fb after seeing an obituary of his half-brother by the same mother (I said it's a real long story), which told us the name he goes by. He took the DNA test, verifying it all. He's a very cool guy, which helps. And he helped me get started on his/my father's father's side of things. Lots of detective work, and I'm back the the Spotted Cow!
So that's why I've been quiet.
