I know the name of a three other people involved in San Francisco’s Fortean Society—but not much more than that.
About Richard Lamb, I know nothing more than he lived in Carmel. This is according to Robert Barbour Johnson. Unfortunately, a search of public records has revealed a large number of Richard Lambs who have lived in Carmel at some point in their lives. Absent further information, it is impossible to identify which is the Richard Lamb who was in the Fortean Society.
About the Lawses, I can say a little more. According to the same Robert Barbour Johnson letter, the Laws lived in Redwood City. They were Albert and Phe. Likely, then, the Albert Laws in question was born 19 February 1924 in New York. He died in Monterey County on 25 November 1983, according to the California death index. I have sent for, but not yet received, a copy of his death certificate, which may provide additional leads.
