Nitpick on number 11..
in reply to a message by bananarama
Gwen is not a nn, it is a full name in it's own right. Also, as far as I'm concerned, Jessie and Jenny are not fine in their own at all. They are childish nns and not suitable for a legal name on a full grown adult.

I agree. I actually think Sam and Alex make better full names than Jessie and Jenny, because they're not cutesy. So obviously it's subjective.
