The people I was at school with in the 80s are making a come back! I have just heard of a couple (East London based and both quite arty/trendy) who are friends of friends and they have called their baby girl... Lisa.
There were several Lisas in my school so it was really popular (Lisa Marie Presley probably had something to do with that).
Now I think about it I guess it is quite a nice name; short, not too cutesy with its A ending rather than an IE or Y... What names have you heard recently that have surprised you?
