Well that's quite a mix of personalities. Bill Gates is closest at 17 degrees, with Taylor Swift a close second at 18. Joseph Biden and Michelle Obama round out the closer ones at 19 degrees.
Taylor Swift is also an 8th cousin once removed. Amusingly, a cousin's daughter has been mistaken on the street for Taylor Swift (tall, blonde, stylish . . .). It's a different side of the family, so we can't credit that to shared genes, I'm afraid.
Bill Gates is also a cousin - 9th twice removed. There are a couple more too far removed to mention.
