There's a lot of places in California that start with either "San" or "Santa." Is there a reason for this? It has a close proximity to Mexico, where a lot of people speak Spanish, so is it something to do with that?
What Phrossack said, I'll add specifically that "San" means "Saint" and "Santa/Santo" means "holy".
The whole part of the US that we stole from Mexico has lots of place names like this. San Antonio is a city in Texas for example.
