My little brother and his wife are TTC and, if they have a little girl, they want to name her Kaelyn (or some deviation of that particular spelling) Rae. Kaelyn is my brother's feminization of a character (Kalam) from Steve Erickson's Malazan Book of the Fallen and Rae is my middle name and in line with family tradition.
As much as I'm touched that my brother would want to use my middle name (and not some other R name), I also find Kaelyn to be really really nauseating--it is trashy, trendy, and juvenile. My mother absolutely loves it, and it really isn't as bad as some of the other name choices he's thrown out there for boys or girls.
During our conversation at dinner, he had indicated other people at work had expressed
dislike for some of his other names but that this was one name no one
Is there a tactful way to tell my brother that I really do not like his name choice? Or should I keep my mouth shut knowing 1) they aren't pregnant, or, even if they were, 2) it may not be a girl and, even if it was, 3) it is not my child?
