Sorry I am so late to the party. You are related to my husband through your grandmother Dessie and her mother, Sallie Farmer Bearden. What I have on Sallie is pretty spotty and you may already have same info. We were told there were 3 siblings: Raymond, Bessie, & Dessie, but it looks like Raymond was from George Bearden's previous marriage w/Ada Goss. Raymond was very young when Sallie became his step-mother, thus the confusion.
My husband is descended from one of Sallie's children prior to Bearden (she had four before she married Bearden) We think Walter McMunn may have been the father of those first 4 kids. We have a little more info on Sallie's ancestors. If you are interested on comparing notes, let me know. Good luck on your search. Julie
