The name Wales is a boy's name of English origin. Wales and discussed in our forums with posts like "CAF (International Pen Pals)".
From the experts:
Place names for boys are few and far between; this one would make a singular choice. Prince William of Wales uses this as a surname when required, as in his military life; Jimmy Wales is the entrepreneur behind Wikipedia, Clint Eastwood played the eponymous character Josey (!) Wales in the 1976 The Outlaw Josey Wales.
