There was a Queen Emma, she was Edward the Confessor's mother but it probably is too common for them. They won't use Charlotte as Diana's brother had a baby called that last year. I expect they'll be very boring and use Elizabeth to please queenie. I agree that George is likely as well.
Blimey! I didn't realise he'd had ANOTHER child. That makes 7 now.
Actually he's probably overdue to dump the child's mother in some hideously insensitive way and move on to the next unsuspecting woman.
