Gytha of Wessex the daughter of the last Anglo-Saxon king of England married Rus ruler Vladimir II Monomakh after fleeing from England conquered by Normans. The "queen" of the Rus was effectively Anglo-Saxong emigree.

Her great-great grandson was Alexander Nevsky, widely recognized in Russia as the greatest national hero.

It seems many anglo-saxons migrated to Rus after the conquest.
