Every European is related Charlamagne.
"In 2004 mathematical modeling and computer simulations ... indicated that our most recent common ancestor probably lived no earlier than 1400 B.C.and possibly as recently as A.D. 55. "

2004 - 800 is a lot longer than 1778(or even 2024) - 1200.
Sure, but that's probably still just sample bias of presidents all being at least mostly anglo-saxon. Probably everyone on the British Isles is related to King John.
Seems unlikely in the 1700’s we’re talking ~20 generations and a population of 8+ million. It’s more believable if we are talking genetics, but ancestry.com is working off of official records.
