Proper names are particularly difficult for pronunciation because it is impossible to know how to pronounce them. The normal rules and trends which usually apply to normal words are very often remarckably absent from proper names, especially surnames and place names. So what we need for this is a good pronunciation dictionary for proper names. The link below provides just that, a searchable on-line dictionary of proper names with sounds. Look for the word you need and listen to it!
