My "three score and ten" is very near. Please respond faster? In your first reply, did you mean "Mattie was your granny's sister-in-law"? George Naves wed Mattie Lee Pope after death of her husband George Davis in 1936. Per Social Security Claims: Mattie Lee Naves (24 Dec 1905 - 14 Jul 1992) was the child of Mark Pope and Mattie Woods. She was the only child from that union. Her father remarried and sired additional children. RSVP.
