The Saxons, Angles and Jutes that invaded after the fall of Rome all generally came from Denmark[1]. Most of the Norse who subsequently invaded in the 700-1000 were either Danes or Norwegians[2], and settled in pretty large numbers in East Anglia, Northumbria and Mercia. Then the Normans, who were in large part Danes and Norwegians that had gotten bought off with a piece of France came over in 1066. I don't know how accurate this is, but in Bernard Cornwell's Uhtred series, English and Danish are different enough that they aren't really mutually intelligible.
