Bear in mind that Geneva, as well as some other parts of Switzerland have very mixed populations with lots of immigrants. So the unusual names might be non-Swiss originally. Most people in French Switzerland use French names, and German Swiss use German names. I can't pinpoint to any "typical" French Swiss names (and I've spent quite a lot of tme in the area. A google search of Isaltina would more bring to believe it's a Hispanic or Portuguese name (no idea of the etymology, though). The Romantch speakers have their own names but they're a minority
Ladino is another word used to designate Romantch.
