One thing I find interesting in the labels of place names here, that I've also found in similarly old Bay Area content: Spanish names written in English where there seems to be confusion between "o" and "a", especially at the end of the word. Examples I see here: San "Gregoria" (for Gregorio), San "Ignocia" (for Ignacio). Some I've seen in another source, but not this map, were "Sausalita" (Sausalito), "Colmo" (Colma). This reminds me of how older Americans born around the early 20th century, including one of my late grandparents, but also people in old movies, used to pronounce words like window ("winda"), tomato ("tomata"). Hearing "San Francisca" or "Sausalita" in those dated accents is totally not far off.
