On my mom's side, I'm 3rd generation American. Her mother's side is off the boat Irish, my biological grandfather was half Comanche, and half Irish. My step grandfather was Russian.
My Father's side is, Swedish, French, and a whole bunch of English. His side we've traced back to the Mayflower crossing.
My mother's side has roots in both Northern and central Ireland. I had relatives who fought in the Ulster Volunteer Force, and the original IRA.
Famous relatives include Clyde Barrow, from Bonnie and Clyde fame, a few of the first noblemen to back Henry up on the protestant change, and a very little known poet that was big in the 1700's England.
My mother's side claims Anne Bonnie, the Pirate Queen, a few notables in the fight for Ireland's independence, both Protestant and Catholic. Honestly, I think everyone from that area of Ireland claim's some connection to Anne Bonnie, so I can't attest to that bit.
