Fascinating! Not only the cool find, but the history you've discovered. English history in America doesn't go back quite that far, but I do live in an area that saw settlement in the early 1600s. The Chesapeake Bay region; you know the story: John Smith, Pocahontas.
My house sits on old farmland. My street was the original driveway to the old farm house which my community used as a clubhouse. It was built in the early 1800s. Beautiful bones on the interior, but became too dilapidated and my community decided to tear it down and build a new clubhouse.
If you look carefully, you can see the remains of a circular driveway in front of the house which now of course is a vinyl clad monstrosity.
They put an Olympic sized pool in the backyard, and the old boat landing on the river behind it was dug out into a marina.
It's so interesting to me the differences in the way land use developed in the Old vs. the New World.
My community is an early iteration of an HOA. We only pay $15 a month and the biggest rule is all about fences. No fences in the front yard!
But HOAs are an entirely different subject, so congrats on the cool find and legend for the grandkids.
