Duke of Normandy as the reign of William II (1035–87), the ruler of Normandy could style himself "prince and duke, count of Normandy" as if unsure what his title should be. The literal Latin equivalent of "Duke of Normandy", "dux Normanniae", was in use by 1066, but it did not supplant "dux Normannorum" until the Angevin period (1144–1204), at a time when Norman identity was fading. Richard I experimented with the title "marquis" ("marchio") as early as 966, when it was also used in a diploma of King Lothair. Richard II occasionally used it, but he seems to have preferred the title duke.
William Malet (companion of William the Conqueror) "Domesday Book" also mentions a Durand Malet, who held land in Lincolnshire and possibly some neighbouring shires. This may be William Malet's brother, but this is not certain. On screen, Malet has been portrayed by Peter Halliday in the two-part BBC TV play "Conquest" (1966), part of the series "Theatre 625", and by Gawn Grainger in the TV drama "Blood Royal: William the Conqueror" (1990). He had married Hesilia (Helise or Elisee). He was succeeded by his son Robert as Lord of Eye and Sheriff of Suffolk. His other son Gilbert founded the Malets of Shepton Mallet. He died around
