My Father, Dickie "Peepsite" Flowers recently passed away taking with him any of the close guarded hints he may have had to help answer my riddle. Who was he really?

This much I think I know... After he was born in Greenwood in 1944, his mother, Floyd Lee Wates (Flowers) never married his biological father. Thus lending him her Father's (Joe Flowers) surname. I have seemed to verify Joe Flowers as one of (the many) sons of Cicero Flowers. It is rumored that his (and his sister Mary) shared a father who was a Porter in the Army Air Corps stationed at AAF Greenwood named Herbert Carlton Walker. (My father also believed this to be true.) I have heard that Herbert Walker was from Texas, Arkansas, and Mississippi but I have not been able to verify any of this.

He and Mary were raised by their Grandfather and Grandmother, Joe and Cora Flowers until around 1962 when he left Greenwood. He ended up in Oregon in 1967 where he met my mother, got married and had 7 children. Nobody in my family knows where he went for sure but I believe that he was on the same search I am, just trying to figure out who his father was. Any clues, hints, rumors or facts about my family would be GREATLY appreciated.... Thanks in advance.
Sincerely,

Franklin Flowers.
