I didn’t have any ancestors in New England at the time, but my Revolutionary War ancestor was in the Virginia militia and was at the siege of Yorktown. I don’t know if he ever saw George Washington in person but probably a good chance that he did.
I had one ancestor who led one of the charges at the Battle of Yorktown with Alexander Hamilton. He served with LaFayette and on one of LaFayette’s trips back to the US, he attended a banquet in his honor on Lansing’s front lawn. I’ve seen correspondence go by ebay between Washington and another of my soldier ancestors but the price was way beyond my means.
On mother’s side they were Southern and much poorer. That ancestor was driving a supply wagon and was on a hill watching the battle. Another Virginia ancestor was in the Navy and captured by the British. Military both sides, all the way back.
Forgot. The ancestor who corresponded with Washington was widowed and left his infant with the Alexander Hamiltons who lived across from Washington. The little girl was taken to dance classes by Martha Washington.
Forgot again. Another one of the 5th ggfathers was a Colonel of the Second Pennsylvania Line Infantry during the winter at Valley Forge. His order book still exists. He commanded it during the battles of Brandywine, Germantown and Whitemarsh. So he MUST have known Washington.
