How can I find out what my ethnic background is?

I am curious. I want to know specifics.

First start would be googling your surname and finding the origin. http://www.houseofnames.com/

Look at your fingernails.....you can always tell if you have a touch of the tarbrush in you by your fingernails.

Try doing a genetic test.

I know I have some irish in me, but i don't look it. I know my fathers side is norweigen/irish, but my mother was adopted and i want to know my ethnicity based more on my features rather than a family crest lol. I have hazel eyes, olive skin, dark brown hair...
