Esperanza and Hope, have been used as names, as have Elpis and Sperantia. However, I noticed in the database that there wasn't a French name meaning "hope." Unlike most other Romance languages (and most Western languages in general), the standard word for "hope"--espoir--is masculine, which I found rather peculiar. I did some digging in the dictionary, though, and found the less common word for hope "espérance," which is feminine. It has been submitted to the database, but not added formally, and I'm not even sure if it's actually used as a name in France (or other Francophone countries).
So, what do you think of Espérance? Good name, or trying to hard?
