I only like
Casey on a boy. In fact it is my next name up for a boy.
I have known four boy
Casey's I believe, one is spelled with a K.
I have known three girl
Casey's I think, one at least is with a K also, not sure about one of the others.
Kaylee is ok, I think I would spell it that way as well.
I think I only know one little
Kaylee who is two.
