I've read that if you have ancestors that were here previous to 1690, then, due to the entire population of people being so small, that you are related to every other American currently alive who also can trace their ancestry back to a person living in America previous to 1690 - and I believe that I read that Barack Obama's American ancestry DOES go back there, and so although he may not be interested -- but some day his daughters might be interested in this. And all of them would be be related to many millions of Americans, who simultaneous are all related to oneanother through those very early ancestral connections.
I doubt it, because only his Arab and Moslem roots (and not his black African roots, which are less than his 50 per cent roots in white America) are of any interest to him.
