Can't decide on a name for a girl.....?

My wife and I are trying to find a name for our girl that is on the way. We are looking into something old fashioned. Right now we are currently thinking about Hortense, Wanda, Mary Todd, Martha, LuLu, DeDe, Francine, Beatrice, Beverly..... but, can't decide. Were seriously thinking Hortense, since the name is making a comeback but, there are already 3 at Biff, our son's, school.... Which name do you think we should pick?
