I have an Alexander Thompson who arrived in Humboldt County (probably Eureka) in 1905.
Cannot find him in the 1910 cenusus.
In 1920 his wife is living with a dau. in Contra Costa County, and says she is still married.
By 1930 she is in SF and says she is widowed.
Since he was in the lumber business, I do not find it unusual that they lived apart, however, I can find no trace of him.Nor can I find any death record sources online for that period of time.Does anyone know?
