A little different

My s/o has been completely oblivious to baby names. Hasnt suggested anything at all but its a hard NO to everything I like or suggest.

Last night he rolled over and said "how about monte. But as a girls name."

So i guess my question is, is there a feminine name to give the nickname Monte? I had originally threw this name out there for a boy full name being Montgomery but he says we should find something else . I'm coming around to the idea of a female Monte but i need opinnions and suggestions.
