I have found John C and Delia B McAllister in 1910, 1920 and 1930 US census. I have not found death records. My mother had their marriage as Oct 22, 1904 in San Francisco but I haven't found record. I 1910, my great-grandfather John Coumbs lived with them. In 1920 & 1930, Katie A Sarralia b. abt 1870 in Rhode Island lived with them. She was described as John C McAllister's sister-in-law in the census.
