I see a death for Jeanne Allan on the death index on familysearch.org. It is on pg. 24 of the 1930-1939 records covering Aabel, Arnold-Hetterman, John. The place of death was San Francisco (the code number for SF is 90), and the date of death was 24 Oct. 1932. There are a few James Allans listed on the same page, and two died in San Francisco. The most likely match seems to be the one who died 9 Sep. 1933, as his spouse's first initial was listed as J.
