Does anyone know anything about my Great-Grandfather? Walter E. Jacques was born in 1903 and died 1963. Is anyone related? Looking for his eight siblings, would have Jacques as original last name. Know that he applied for social security number under Jock, and used different last name before he died. He is buried under Jacques. Changed his children's last name to Jock in the 1920s. Please if you have any information contact me. Thank you for your time.
