Margaret Marie Hilliard Gay

I am seeking information on Margaret Marie Hilliard who was born in 1916 in Texas to Earl and Ida/Ada Hilliard. She had a child Robert Leonard (Bobby Lynn) GayJune 24, 1934 in Haskell, Texas; the father was Ernest Leonard "Dock" Gay . I assume that Margaret and Dock were married in 1933. Dock died in Roswell, New Mexico March 10, 1939. Bobby lived with Dock's family in Louisiana until possibly 1940-1944. Margaret reclaimed him about that time. I know that Bobby died in California in 1964. I would like to knowabout Margaret's family and what became of her, and where she is buried if deceased. Thank you, Phillip
