Biography: 

Mink tells warden that his and Flem's "grandpaw had two sets of chillen" (Mansion, 114). So presumably this ur-Snopes was married twice. Reason to identify Flem, Mink and Ike as chillen of second marriage (Flem's Grandmother). Is this man and first wife ancestor of the rest of clan too?
