Felícita sounds pretty, but since most of the google results I find are baby name sites or businesses and not actual people with this name, I have no idea if it's a real name or not.
According to Wiki there are three Roman Catholic saints named Felicitas, two of them being martyrs (thoug one of them may have not really existed) and another being a nun of the IX century. So yea, it should work well whether with or without the last "S".
