There is a lot on the son, George H Slatford, at familysearch if you search for his name with his date and place of birth.
He married Mary Stellmacher in Los Angeles in 1912.
The California Birth Index includes mother's maiden name and I didn't find anyone born Slatford with a mmn of Stellmacher.
1930, divorced and rooming in L.A.
1942 Draft, next of kin is not a family member.
from the "other site"
I didn't find him in the 1920 census.
On the 1920 California voter rolls - he is the only Slatford registered at his address.
1921 LA City Directory - the wives' names do not seem to be included with the husbands, as they sometimes were, so it proves nothing that he is listed by himself as a motorman living at 955 Girard.
Oddly there is a US Army Transport Service departing passenger list saying George H Slatford of Alta Vista Apartments, LA, departing 12 December 1917 from Hoboken, NJ. Nest of kin: Mary Slatford, sister. < he had no siblings as was mentioned, at least not on the 1900 or 1910 censuses where you'd expect them.
I didn't find a WWI Draft Registration. If there is one, it will say whether he is married or not and claims an exemption for that reason.
A Marie Stellmacher marries Mark J Mead in 1919 in Los Angeles. No telling if that is the same woman. She had married a man named Wilson in LA in 1909.
