Surge of Lisas

Don't ask me how I found this web site...but it's wicked cool; Baby Naming Wizard. What I find most fascinating is to follow the continuum of a name through time, its surges and disappearance from societal use. Quite frankly, I don't know why "Lisa" hasn't had a massive comeback since its #1 ranking in the 60's. I think my parents were a little past the curve...but I still like the name.
