I have NO IDEA what my ancestry is. All I know is that my parents are both English; my stepDad was raised in Scotland and Germany (as my grandparents were in the RAF) and has a scottish surname ("Scott" - how very unusual :P) but that's it. My biological Dad's surname is Boniface, so I guess there's some Spanish in him somewhere (if Boniface is derived from a Spanish name - I forget now), and I have a very Roman profile, so I guess if we went far enough back I'd be Roman too, but what the hey. My blood comes from all over the shop.
It does amuse me the way people say "I'm 1/2 Spanish 1/4 french 1/8 english and 1/8 welsh" as if that was their nationality - as if your nationality made some sort of big difference to your genus.

(Although it amuses me more when people say "I'm 1/3 German" - 1/3, hey? Reminds me of a letter in the back of New Scientist - poster up in the Underground for Thirteen Ghosts with the tagline "terror has multiplied" and some wag wanted to add "multiplied by what, idiot? 13 is a Prime number".
I ramble. Whee!
