. Written interchangeably in records as:
Roi,
Roy,
Le Roy, and
De Roy, the surname Le Roi originated from the
Normans, the descendants of Norse
Vikings who settled in
Amigny, a commune in
Manche,
Normandy. It derived from the
Old French roy,
roi (), meaning "king", or "the king" which was a
byname used before the
Norman Conquest and a personal name in the
Middle Ages. The Normans, or "Northmen", after having settled in their new lands in Northern France, quickly adopted the Old French dialects of the region and would later take their language and naming practices with them to England. ==As a given name==
