I don't know what it is, but I see
Jane as a little hellion of a name. Like a
Scarlett O'Hara type - sweet as pie when she needs to be, pretty, but scheming and smart, driven and tough as a nail. It's got a kind of ballsy
Rosie the Riveter energy, and I could easily see a
Jane as being an adventurous, loud-mouthed type who gets herself into heaps of trouble and loves it.
I'm not sure where I got that from, because most Janes in books and such are shown as being meek, mild, and domestic - my idea of a
Jane is the total opposite.
Therefore I like it.
