I like to say my characters pick their names. As I'm making them, I'm sort of thinking about names in the background and once I'm done, I'll look through a book of names unitl I find one that fits. I may have a different idea, but when I try it out on the doll, if she doesn't like it, it doesn't fit and I have to keep looking.
When I sold dolls at a weekend market years ago, I know I lost one sale because I didn't have a doll with a gentleman's granddaughter's name, so it can be a risk and it's not for everybody, but I believe all my characters are unique individuals and deserve to have names.
