I am searching for any information on the marriage of David Christian Neidhardt and Constance D. Tarr. David was born Dec 9, 1908 in Nebraska and died Dec 23, 1988 in Los Angeles, CA. I believe his mothers maiden name is McCord. Constance in the daughter of John Cecil Tarr and Matilda Nelsina Johnson. She was born Mar 23, 1909 and died Nov 1982 in Los Angeles, CA. They had two sons: David and John.
