The KC won't change the name unless there was a mistake on the registration form. I believe there was a kennel of Weimaraners called 'Hansom' so suspect that is why they disallowed the name with Handsome in it, as it could be confused with the other kennel name. This is why the breeders have to submit two names for each dog.
I once had a whole litter returned as I wanted to call them all 'Heart' such as Lonely Heart, Lion Heart etc, but 'Heart' turned out to be someone else's kennel name.
It is pronounced Fear 'nort' meaning 'fear nothing' .
