My family has an unholy obsession with geneology, and because of this, I can trace my roots back to the, I kid you not, 900's. (On my mom's side at least)
My mother is purebred WASP, with a pinch of german. Her family did all the things commonly ascociated with Anglo Saxons. (Hastings, victorian England, stonhenge, ect.)
My dad's side is a little less clear. He is >90% Irish, with possibly a speck of french. His family grew up in Ireland, and did tpyical Irish things (Drinking, praying, drinking, fighting the English and drinking.)
I wouldn't be a bit surprised if my families have fought and killed eachother at one time or another, seeing as they were mortal enimies.
