My records from an old Bible give the marriage date of William Rittenhouse, b. 1755, and Rebecca Bray, b. 1759, as May 19, 1777. Both were from New Jersey and later settled in Fayette Co.,PA. I understand that other researchers claim William had two previous wives, and that some of his 12 or 13 children were from those unions. Does anyone have in additional info on this marriage?
