Ooooh! Girl names!! Since I only have boys, I have a whole bunch of girl names saved up! lol
Since Emma is a bit of an "old-fashioned" sounding name, here are a few others that I think sound good with Francesca...
Oliva Francesca
Amelia Francesca
Bella Francesca
Hannah Francesca
Sonia Francesca
Just a few suggestions... Good luck!
