I can't find my father, Francois Paul Leon Mouchet in the 1930 census.  He usually went by Frank Mouchet or F. Paul Mouchet. He was born in Canada (British Columbia) on 14 November 1906.  In the 1929 Los Angeles city directory he's listed at 8642 Gregory Way. In the 1930 L.A. city directory he's listed at 1654 Murray Drive.  In his citizenship application he also listed 1426 Edgecliff as an address for that time period.

I found the rest of his family in the 1930 census without any trouble and he wasn't with any of them. His twin brother George T Mouchet was living in Washington County Idaho, his sister Suzanne Mineo was in San Diego and his step-father, mother and younger sister were in Clarkston, Washington (Nathan, Marie and Helen Randall).

I never found him in the 1940 census either. He was supposedly
 living at 715 North Kenmore in L.A. at that time.
