Hello again, Terry,
In further reply to your question, Hubert is listed as single when he arrived back in California from Auckland on the MARIPOSA 16 May 1936. He was 40 that year - probably a confirmed bachelor by then.
In 1937, he was still with the Canadian Bank of Commerce - that's a 21-year, at least, career with the same employer. Perhaps that bank has an archives?
Cheers,
Westoe
