England has quite a few names ending in <wich>. For most of these the pronunciation is ɪtʃ, though you may hear native speakers who pronounce it ɪdʒ instead. Here are some examples:
Bromwich Dulwich Dunwich Greenwich (= ˈɡrenɪtʃ) Harwich Norwich Woolwich
I can only think of three names which do not follow this pattern. These are Ipswich, Nantwich and Sandwich. In these names the ending is pronounced wɪtʃ or wɪdʒ.
Petr Rösel adds Colwich, Prestwich, Northwich, Middlewich and Droitwich as place-names where <wich> is pronounced wɪtʃ or wɪdʒ.
