Hi James....thanks for responding to my query...I too have a Isaac Vansickle a U.E. Loyalist.He had a dau. Sarah who married Henry Weaver...I don't think we are talking about the same Isaac....but yours could possibly be a son of Isaac. Unfortunately, I only have the name of his daughter. I will however check out Pioneers of Beverly and see if I can find out more of him...His dau. married in 1824 so you see our dates do not correspond.I certainly will keep you updated if I find any thing else... Kindest regards Barb.
