Although Anglia is/was a UK area it is not generally known as such anymore - some people still refer to an area called "East Anglia" and there are a few references if you check Google.
Some history can be found here: http://www.norfolkbroads.com/guide/history.htm
As a .org it might be of interest more to a group/individual fond of the old Ford Anglia car - check Google for "ford anglia club".
Anglia.ac.uk (Anglia Polytechnic)
It looks like it is still referred as Anglia.
But i am sure that you know better as you are from UK.
It's obscure even for someone living in the UK - maybe that's to your advantage, the fact that Anglia is still listed may mean that some people are anxious to keep the term alive - just find the right person.
