I only like
Kay for a boy. Somehow I think it sounds NNy for a girl, but not for a boy. Combos I like:
Kay MichaelKay ArthurKay EdwardKay Rupert
However, as I'm thinking about it now I realize that it sounds a lot like gay, especially if you just say it without specifically emphasizing the k. So I think that would put me off of it for either gender -- not because I mind the connotation, but because I tend to stay away from any names that sound a lot like words. I don't consider using Annalise either, even though I like it, because I can't "analyze" and "anal-lise" out of my head. Same with
Tobin. I always hear toe-bin. So...that might be something to think about. It might not bother you as it does me.
