My mother's (Ethel Harper) mother was "Lou", "Lu" (spelling?) Rabon who married Samuel T. Harper. She was born in Plantersville, SC in 1892 and died in Sumter, SC in 1986 at the age of 93. Her six brothers were Alan, Weston, Sam Jr, Charlie, Clarence and Floyd.
"Lou's" mother and father could have been Fannie Parker and David Rabon.
