I've always disliked Peter, just as a collection of sounds - I can't put my finger on any other reason why. The first one I ever knew was a perfectly normal, not particularly memorable boy at school, so I don't think it was anything to do with him. Since then I've known nice and nasty ones, but none that were spectactuarly evil or anything. I dislike Kelly as a collection of sounds too but quite like Kerry - what a difference a change of consonant makes!
Not one I would ever use anyway for cultural reasons, but I don't like the Sikh name Surinder because it makes me think of the word "syringe" and then, by extension, of earwax!
I've never met one in real life, but why on earth do some people think "Brie" is a suitable name for a person? It's cheese!
Jade and Nigel because nearly everyone I've known with those names has been horrible. It's possible I would change my mind about those if I knew nicer ones as it's definitely the association, rather than the names themselves.
And unlike some people here I really like Jane, Ruth and Matthew.
