Wow! Thanks for the dates. So, Kit seems to be the "oldest" of the girls. Which is really funny, as I always assumed she'd be the youngest.

The books aren't really consistant with dates (just look at Kit's birthday, that means she turns ten in 1933, so her first books must take place late 1932/earl 1933). I kind of like this, they don't pretend history didn't happen, but center the girls around actual history.
