Ever heard of Liliah? That's what my son and DIL going to name my new grandaughter in May. The first girl was named Sarah. I though that was so special that they would name her after my grandmother. Come to find out they got it off a Buffy series.
No, I've never heard of it but it sounds pretty.
Funny about the Buffy/Sarah thing. I have some friends that named their daughter Sarah because they like the Jefferson Starship song Sarah.
