In old Norse, the name was Mon or Maon and in Latin it - as well as Anglesey off the Welsh coast - was called Mona. Local people, I believe, refer to their home as 'Ellan Vannin' or 'Ellan Mannin'. The modern form 'Man' is just a variation on these ancient titles. Click http://www.rootsweb.com/~engiom/ for more information.
