nothing to say 'cept, Norman conquest effectively ended with 1066 and the Battle of Hastings. Which was immediately followed by a period of Norman governance and assimilation.
Incidentally, the English language the founders would have spoken prior to the Conquest would have been considerably different, as the Great Vowel Shift wasn't for another 100 years or so (I think).
