The mn is a prime guilty pleasure name spot for me. Names that are either too unique to be a first name, too hard to spell/pronounce, or a combination of both. For our Team Green baby, Pilar, Mireille and Xiomara were our girl mn considerations. I particularly liked the idea of "X" a middle initial.
It's also a good spot for that family name that means something to you, but is too awful to inflict on a child as a first name. I won't give examples of ours because I don't want to offend anyone on this board.
