Gertrude Beatrice Mcclain

I'm searching for any info regarding my aunt Gertrude Beatrice McClain. She was born in Sacramento, California on 26 March, 1922. She still lived there in 1930, according to the Fed census. The family moved to Arizona some time after that but the 1940 census does not show her in the household anymore. I do know she was married and his name was David. Any info much appreciated.
