I caught a live stream of Stonehenge during this past Winter Solstice (it was cloudy, naturally) and the streamer provided a bit of trivia that I hadn't heard before:
George Washington's English ancestors, specifically Sir Lawrence Washington, were the owners of the West Amesbury Estate in Wiltshire, England, which included the land where the ancient Stonehenge monument sits. (Via Google)
If you hadn't that before, welcome to the "Huh, that's a funny coincidence" club.
Land owners also had married within family so I you checked their family tree two persons could be simultaneously spouses and cousins. That's a coincidence!
Rich people have lots of descenders who tend to be rich.
Washington was a wealthy landowner in the British Empire, hardly surprising his ancestors were wealthy landowners.
