California death records show that a Jane G. Neisch died in San Francisco on 7/30/1905, but it also shows her age as "1". This could be a misprint, or it could have been a daughter named Jane, that would have not been listed in the 1900 census since she would have been born in 1904. There is no listing for Walter, however online vital records for California don't staret until 1905.t
