They lived in the San Juan Bautista/Hollister area of California. My Grandfather died prior to WWII and my Grandmother died during WWII not sure the exact year. The name Dutra and the other names you used in your listing are names my parents have talke about. There is also an Enos side of the family that lived in Los Banos
