I would say that Clinton and Columbia are quite popular.
With only 40 non-living presidents and 365 days of the year, more things get named for presidents than feast days. In the Latin World, Spanish, French, Portuguese, and Italian explorers, after naming features for all of the important people in their parties, often resorted to naming features after the feast day on which they were discovered (or near which they were discovered or named). Nacimiento Lake was named for Christmas, Ano Neuvo Beach for New Year's Day, and San/ta almost-everything for the feast day.
This results in a lot of duplication amongst California, Texas, Florida, and Puerto Rico or the Caribbean. Occasionally, there are masculine vs. feminine forms and mild shifts in local pronunciation owing to dialectical differences either at the time of naming or the progress of the local accent.
As an aside: A city in Texas and California sharing the last 8 letters in common that don't rhyme ....
Amarillo and Camarillo.
