Jack,

When you are in a hole stop digging!

I think what you are referring to is a graduate of Cambridge University. That itself is made up of a number of colleges.

I'd agree with AHP, it is in East Anglia, which although in the bottom half cannot be considered "Southern England". But then I'm a true southerner. Anything north of Regent's Park is in the wilderness as far as I'm concerned.

Tim.
