These chips. I haven't found anything yet. I don't have access to directories for every year in Benicia/Vallejo. I have also be looking through more recent phone books ( 1955..57...60) to see if I can come up with initials that match those on your chips. I figured they might of still lived in the Benicia area in their later years. I have to visit the library to see if they have other resources to look at.
