Clarence, If your grandmother was a Martha Coleman, from the Bonita/Jones area and she was African American, then she was in all probability my Grand Aunt Martha (Stella) Cunningham Coleman. She was the only Girl born to Robert and Cheney Cunningham among eight boys. She was 100 years old at death in the Bastrop, Mer Rouge, Bonita/Jones Area of Louisiana. My Grandfather (her brother) Jerry Patrick Cunningham moved to Pine Bluff Arkansas around the early 1940's to live with his daughters and only surviving Son Jesse. who was my father. There are many still living in these Louisiana areas as Colemans, Robinsons, Cunninghams, Parkers, Williams, Taylors, Johnsons, and other surnames not mentioned. Please reply if any of this sounds familiar
