Dear Mr Stephens,

The OED has this to say about England [keep it in mind, please, that there are about 200 years worth of citations that I can't read.] Angle-land was the part of Britan where the Angles lived, as opposed to Wessex, Sussex, Wales, Scotland, etc. Since the Normans defeated Harold of Wessex, I assume [guess] they made a more diplomatic settlement with the Angles. At any rate, by 1205, Britan was happily using the term Anglelond. That's what I discovered by walking into the dining room. Any more research than that on the subject will cost you.
