Note: Three Martin Kristovichs in 1910 (at least if this is correct, 3 residential addresses. Two for sure in restaurant trade), but other years show that only one was co-proprietor. But this is the only year two in restaurants. Teamster was around for other years.
Martin Stephen Kristovich was born in Arizona June 6, 1886 and died in LA May 5, 1959 but is young to have been this one.
