> I'd be interested to see the actual chart she made. One possible explanation for how she was able to do this is if each of the presidents connects up to English aristocracy fairly recently, which would account for the records being intact and would be more interesting than just the fact of a shared ancestor in ~1200.

Obama's most recent aristocratic ancestor appears to be a "Sir Henry Bold" his 16x great-grandfather.

A quick look at some of the genealogies makes it appear that many rely on the same source, which lists 900 royal descendants that immigrated to the new world[1].

With 900 of them several generations back, it wouldn't be too surprising that many politicians would be related.
