I think we might have found the French name that Bordroyne, Boardwine etc is derived from--it is either BEAUREIGNE or BEAURAIN. These names appeared as Frenchmen fighting with Layfayette in the American Revolution & goes all the way to the Battle of Hastings with William The Conqueror in 1066-86. I wastold in the past that in French the name "Bordroyne" would be prnounced in French as " Bo (Beau) Dwayne or there about. I know the Revolution was way after Sarah was born in 1709, but the name goes way on back 600 years before she was born. Hopefully we can find a break with this spelling.
