Norman

The Normans were descended from a group of Vikings, led by Rollo, who settled in the north-west of France, at the behest of Charles the Simple. That area, plus a significant area they laid claim to, came to be known as Normandy. A Norman is pretty much what you get when you cross a Viking with a Frenchman.

The 1066 invasion of England by the Normans is a major reason why modern english contains many French words not found in Old English. It is often used to divide Old English from Middle English.
