The Jim Vance (1832-1888) that was involved in the Hatfield-McCoy feud was the uncle of William Anderson 'Devil Anse' Hatfield. Jims sister, Nancy, was Devil Anse' mother. Jim was married to Mary Collins. I've found five children for them so far. Jim and Nancys mother was Elizabeth S. Vance. No one has found any doucumentation so far that Elizabeth was ever legally married. Elizabeth was the daughter of Abner Vance. Abner was my GGGGGreatgrandfather.
