We have three baby name books and we have read them numerous times. We have looked at calendars of saint's names, lists in the Bible and Greek mythology, Shakespeare characters, etc. (We aren't religious -- these are just the resources that are readily available, and we want something on the classic side.)
I just have a hard time getting inspiration from lists -- it's so boring.
Naming was one of the things I was so excited about with DC1 and I feel we kind of "settled" -- I LOVE DD's name but it's extremely popular, which I knew at the time and didn't want, but DH was insistent and I didn't have a better suggestion.
We have looked a bit at family trees, and will do so more, but I doubt we'll find any real treasures there.
Any ideas? Not due for a while but need to start thinking.
