If you will check both the history of San Francisco and San Mateo Counties you will find that San Mateo County was once part of San Francisco County and was formed in 1856 when the current San Francisco boundaries were established. Another interesting item to note is that at one time the area called Hunters Point was refereed to as South San Francisco. In fact, just off of Third Street (Railroad Ave.) near Newcomb and the intersection of Mendell still sits the South San Francisco Opera House. I found a newspaper clipping with a picture of it in my fathers scrap book and later saw the building when I was searching the area for locations my father lived at in the area. Jim in Oregon
