I am coming around on Ruth. It was my grandma's middle name (actually a family surname that I think her parents probably used because it was also popular at the time). I don't think it's one I'd ever use, but I enjoy meeting girls and young women named Ruth. (Although I met a 12-year-old Ruth who, unprompted, said she hated her name.)
Ruth is one of those names that seems like it can only belong to interesting women. I picture an intelligent, beautiful, down-to-earth brunette who cares passionately about some issue(s).
