On my dad's side I'm German, Hanoverian/Lower Saxon on my grandpa's side, Hessian on my grandma's.
On my mom's side I'm assorted Canadian: A large bit of English, some Scottish, some Irish, some French, and some Rhode Island Loyalists that got kicked off their land during the Revolution.
For as red-blooded of an American as I am, it's rather ironic how much of my anscestry was on the other side of the Revolutionary War: George III of England was also the Prince-elector of Hanover, and I have anscestry from Hanover. The British hired Hessian mercenaries during the Revolution, and I have Hessian anscestry. I have plenty of British anscestry, and the only anscestors I know of that were actually in the thirteen colonies at the time of the Revolution were the Rhode Island Loyalists (actually, the guy's father seems to have stayed in RI, but my line of anscestry went to Canada with the son).
