My grandfather is Clifford Clackum of Kennesaw, GA (b. 1915), married to Della Louise Hogan from 1937 - present. Clifford and Louise had several children....Charles (deceased in infancy), Raymond (deceased 1981), Annette, Martha, Larry and Judy.
Clifford's mother was Mattie Lou Clackum (d. abt 1922) and his father was George Wallace. Clifford was raised by his mother's family--Mattie's father was W.C. (Wesley) Clackum who was married to Josephine Dunn. They had several children.
The 1920 census shows that W.C.'s father was born in Germany.
Any info would help :)
