Below is a non-comprehensive list of surnames which are pronounced non-intuitively. (Or one could argue that they are pronounced perfectly sensibly but the spelling is non-intuitive.)
I've also included a count of how many times each surname applies in the 2006/07 Brighton telephone directory, to give you an idea of the relative importance of learning to pronounce each name correctly.
