Looking for some name ideas for my Mastiff?

I just rescued a Neo Mastiff puppy and have not been able to decide on a name yet. She is spunky, fearless, loving, and she blends into the shadows so I am trying to find a name that would fit that personality and the size that she will become! So far I have come up with "Nina", "Luna"(moon in italian), "Nala", "Giovanna"(so I can call her GiGi for short), and someone else mentioned "Electra" I am trying to stay with an Italian sounding name since Neopolitans are Italian Mastiffs. Any ideas?!
