It appears my Williams is NOT related to yours. Mine, too, resided in Wallingford in New Haven County, but Willoughby Williams Sr. orig. came from England and was born abt. 1736. A weaver by trade, he Married Abigail Allings on Jan. 22, 1756 and he died in Wallingford on April 15, 1776. A lot of this info was on WFT #8.
