Beauvais History, Family Crest & Coats of Arms
Soon after the Norman Conquest of England in 1066, the name Beauvais was recognized on the island as a name for a friend, and is a somewhat nondescript form of affectionate address, somewhat like pal or mate in modern English. The name translates from the Old French root belfiz of the same meaning. The modern French meaning of the word as son in law was not in place until 1468.
Other sources claim that the name is a local surname from Beauvais in France. and there, we found that "Duke Richard II. in 1027, confirmed the gift of Ansgot de Belvai of land at Belvai to Fescamp Abbey. Fescamp (Fécamp) Abbey is a Benedictine abbey in Fécamp, Seine-Maritime, Upper Normandy, France.   Founded in 658 by Waningus, a Merovingian count, the abbey still stands today.
As to agree with this postulation, another source weighs in on the debate by simply stating "The town of Beauvais, in France, is however a more likely source for the surname."  This author continues "Sir Bevys of medieval romance seems to have no place in veritable history, though Heylin claims him as a real Earl of Southampton. The first instance of the surname that I can call to mind is in Sir John Bevis, or Befs, who took Richard, brother of King Henry III., prisoner in a windmill at the battle of Lewes, in 1264. "
