Declensions of the names of ancient cities

Salvete omnes. Does anyone know a good website where I can find the declensions of the names of ancient cities? I am looking for the the genitive case of “Corinth”. Example: Bellerophon erat filivs Glavci,rex (Corinthi?) Thank you in advance.

Please belay my request. I found it on latinlexicon.org.
