Yes, it is as a middle name. From his comments I doubt this would even be a question if it was first name, i.e. no. I suppose middle names offer more opportunities to be creative and honoring, although I still imagine it raises an eyebrow when the name is more clearly identified with one gender than the other. I wonder why they don't go with something like Kimber, or Kim as opposed to Kimberly. I actually know through work an older male Kim (of course I don't know if he shortens that).
A lot of kids I guess never even know their classmates middle names, except maybe friends.
