There is no "American" bloodline. Every single person in America (except maybe the American Indian,which is still debatable) has the blood line or lines from all other countries in the world.
a bloodline is stronger than where you live. I never stepped foot in Ireland but I sure know that if it wasn't for a whole lot of blood born Irish citizens I would not be alive and breathing.
