Rebecca Hatfield

A friend believes that she is related through her Grandmother to Devil Anse Hatfield....She still lives in Logan County West Virginia....The information that I have is that Anse Hatfield(or probably 1 of his sons married and had a daughter named Rebecca who married a man with the last name of Vance...My friend's Grandmother's name was Tilda Vance , she married a Moses Marcum....Any information that could help me sort this out would be Greatly Appreciated....Thank You !
