I think it'd be a little gross to name a girl something that comes from a name meaning "man power" (more about that if you click the
Montgomery link). But if it's a surname in the family, I don't mind it as a mn.
Monty is a unisex nickname, IMO. It makes me think of Canadian Mounties a little bit, which brings to mind
Dudley Doright, but that's beside the point.
WDYT of
Monty as a nn for these girls' names:
SimonetteDiamanta (form of
Diamantina)
