It doesn't really matter whether a name is spelt in a different way from the norm, in my opinion.
An Irish acquaintance of mine was very critical of a relative's name being spelt Kieran. She insisted that the correct spelling is either Kieron or Ciaran. Frankly, I don't care what the more usual spelling is. There are different ways to spell a name and, in my view it is rather petty and discourteous to be unwilling to accept the name that a person has been given.
Despite living here, the person who took issue with it was, perhaps understandably from a historical point of view, not a great fan of England and may have felt that an English person taking an Irish name and then spelling it differently was some sort of snub.
Is it acceptable, though, for a person to question, or indeed change, the spelling or pronunciation of another person's name, on the grounds that the spelling/pronunciation is not the norm or is seen as "incorrect"?
