The search for Sandford out of the earlier Koreatown post led me to this 1918 map of city of Los Angeles annexations. It's not the later colorized official map I've referenced here before, but it was done by the city engineer of the time and has abundant info. I just spent an enjoyable 20 minutes reveling in the details, such as Sunset Boulevard stopping in Beverly Hills, the Los Angeles River originating in Encino (not at the Canoga Park spot generally accepted today), the rancho names like Rodeo de las Aguas and Providencia, the location of rail lines and old settlement names such as Marian (now Reseda) and Dundee (part of Sun Valley.) No mention of Sandford; its tract was part of an unnamed 1909 addition to the city. Click here to view the map full size.
About Sandford: LA Observed contributor Bob Timmermann, who works at the Central Library, found no mention in the big California gazetteer of place names. "And that book is pretty thorough," he says. "It's about 800 pages long."
* Got some answers: It should be Sanford to begin with. Update
