The English language is not the most logical of languages when it comes to pronounciation and town/village names are even worse
Here are a couple of pointers to the ones most often mispronounced, maybe some of you can add more?
Hawkinge = HAWKINJ
Lympne = LIM
Blenheim = BLENIM or BLENEM (I believe Germans do pronounce it BLENHIME)
Bekesbourne = BEEKSBORN (that is the actial name of the Canterbury field)
Folkstone = FOKESTON
I have a village near me that is spelled Trottiscliffe and pronounced TROSLEY so you can never be sure
