Just stumbled across this trivia bit and found it fascinating:
"Ashton’s paternal grandfather, Earl F. Kutcher, was the brother of Ashton’s maternal great-grandmother, Leona Alice Kutcher. Thus, Ashton’s parents are first cousins, once removed." http://ethnicelebs.com/ashton-kutcher
It's so rare to see that in modern America, especially with a celebrity. Can anyone think of other examples involving well-known folks?
