With some basic information on the family from Ernie, I used the California Death Index to find Norma.
California Death Records:
Last Name First Name Middle Birth Date Mother Maiden Father Last Sex Birth Place Death Place Residence Death Date SSN Age
MARTIN NORMA KOCH 04/23/1921 F MISSOURI LOS ANGELES(19) 05/01/1979 553-28-2953 58 yrs
I then extracted a list of children who had a mother named Koch from the California Birth Index.
CA births with mother's maiden name Koch:
California Birth Index, 1905-1995 about Jules R Martin
Name: Jules R Martin
Birth Date: 23 Jan 1963
Mother's Maiden Name: Roch
Birth County: Los Angeles
I looked up this Jules Martin on the Internet whitepages and gave information back to Ernie so he could call and obtain more information on Jules' mother Norma.
I also found Norma Koch on the census as follows:

With everything put together I now have a short bio for Norma Martin and I am still looking for her history in Hollywood films as a costumer.
Bio: Norma H. Koch Martin, was born 23 Apr 1921 in Kansas. Her parents were Jules F. Koch and Clara Mathy. Norma married Robert R. Martin about 1943 in California. Her children probably include Jules Raymond Martin born 23 Jan 1963 in Los Angeles, California. She died 1 May 1979 in Los Angeles California. She is supposed to have been a costume designer for film and Hollywood.
Sources: CA death records, 1930 US census, and Ernie Koch.
