I am trying to determine the identity of my maternal grandmother's father. My maternal grandmother, Dorothy Kathryn LEE was born 15 Jul 1905 in Big Springs, Texas. She died 09 Apr 1963 in Midland, Texas where she is buried. Dorothy's obit in the Midland Reporter Telegram mentions that she is the granddaughter of pioneer settler B.W. LEE. Dorothy's mother's name is Lilly BABCOCK. Dorothy's death certificate lists her father's name as UNKNOWN.
