I've not personally used it, but the module Lingua::EN::NameCase may be useful. It seems to have a series of rules that deal with cases like the following:

Original            Name Case
--------            ---------
KEITH               Keith
LEIGH-WILLIAMS      Leigh-Williams
MCCARTHY            McCarthy
O'CALLAGHAN         O'Callaghan
ST. JOHN            St. John
