I don't think this will help much, however, I have a william randolph in my family. When his wife applied for a government pension she listed EPRHAIM BUCK as a witness. Her name was Mary Ann (Stanley) Randolph. When I did some checking on census, the 1880 census in Upper Alloways Creek, NJ showed my William's father Charles, living with his sister Elenor Buck. I'm wondering if Elenor might have been Ephraims widow or a widow of a relation of his. Do you have an Elenor (Randolph) Buck in your family tree?
