History books say Anglo-Saxons replaced the Britons in England

Well, now I am lost.  I always thought that Anglos were Britons, hence the name England.
What was the country of origin of the Anglos, in not England?

The britons were celts. The "Anglish" and Saxons were germanic, cousins to the people who settled Holland. You could extrapolate that modern Dutch is essentially what English would have been were it not for the french-speaking Normans who conquered them in turn.

The britons were absorbed by the anglish, mostly, but hung on to their identity in the remote areas, Wales, Scotland, Ireland. Mostly the Welsh are the closest cousins to the britons of roman times.
