Since it’s probably going to be an issue as Obama’s campaign heats up, I’m curious. I’m counting anybody born on North America as American regardless of whether it was before or after the founding of the nation.
Andrew Jackson’s parents were Ulster Scots.
John Quincy Adams’ wife was English born daughter of an American merchant and his English wife.
Not a President, but arguably the most important of the Founders, Alexander Hamilton, was born on the Caribbean island of Nevis and raised in St. Croix.
