Why isn't St. Augustine, Florida called San Augustine?

We have San Francisco, San Diego, San Bernardino, etc. in California. I suspect St. Augustine began life as “San”. When and why did it change?

It was called San Augustin, and was likely Anglicized when the British acquired Florida under terms of the Treaty of Paris in 1763.

St Augustine was taken over by the British about 100 years before we took over California. The Brits anglisized the name.

Ehr, the Spanish is San Agustín, actually. Florida changed its pronunciation from FlohREEda to FLOHreeda too, by the way.

Pardon my misspelling.

There’s also now the rap star Flo Rida, who I believe pronounces his name as “FloRYda.”

I was calling him “Flow RIta” for a while. Just don’t like the “catchy” rap names…
