To summerkingsley,
Just came onto this post. Your side of the Hopcraft family is
the John Sheriff and Eliza(Camplin)Hopcraft side..
John Sheriff was the brother to Wallace Frost Feargus O'Conner..I think this is where the mixup is coming into play, as Samuel Henry was the son of Wallace and he had a daughter named Alice who married Clarence O. Hines...(my grandfather..
In the info that I have there were 18 children in that family..I figure that by now you have all this info but thought I would send it along anyway...
