If Eric Castrobran is still at Point Vicente, he may be able to help with names from later years. (He functioned as the CG's lampist for much of the California coast. His son was active at Point Hueneme. When I met Eric he was a font of information about his light. Don't know how much he knew about the others along the coast, but he did visit them periodically performing his lampist duties.

I'm sure you already have, but just in case, you might want to check with the USLHS in Washington.
