It is amusing how pronunciation has been used as a way of detecting a non-local or an interloper. Place names in England are only one example of such shibboleths. Many other pronunciations such as names of colleges e.g. Gonville & Caius College, Cambridge;  Magdalen College, Oxford; and even mundane locations such as Railway Stations e.g. Marylebone; are all there to trap the unwary, also the correct pronunciation of Cockburn's port.
