I am not related, but just trying to assist.I found this info on the Cal Death records at rootsweb.Perhaps it will assist you in finding living family members (children of the McCorkle/Debusk)female children.Of course, I don't know for sure the first names of their parents, so I can't be sure they are the ones you are looking for...
McNeil,Doris F. b. 13 May 1921, female, mmn McCorkle, father: Debusk, b. California, d. Ventura County, CA 28 August 1994.
Phillips,Joy Bradley, b. 30 Dec 1918, female, mmn McCorkle, father: Debusk, b. Missouri, d. Los Angeles County, CA 15 April 1991.
If you would like to find descendants, death certs and obits would probably need to be obtained.
