I agree that genealogy is what it is...but you can hook your ancestors to anybody you want if you bend the lines a little. For instance the Cheney that obama is hooked to was no were near the residing area where the other cheney's ancestors came from. And there are notes that obama's dunham relatives changed their names in New Jersey back in the late 1600's. I know it is thrilling to want to be related to some person in history. But I am proud of my ancestors if they only came from digging dirt in the Lord and Master's fields.
