Robert Malet
Son of William Malet (d. c. 1071) of Graville-Sainte-Honorine, Seine-Maritine, and Esilia Crispin of Tillières. Succeeded his father in Normandy and a large English fief centred upon Eye, Suffolk, c. 1071. Soon after 1087 Eye was contralled by by Roger Pictaviensis, but by 1100 Robert was back in England in possession of Eye. He received the King's permission to found a cell of the abbey of Bernay at Eye before 1087, but it is unlikely to have been built befor the early year's of Henry I's reign, when Robert was royal chamberlain. His last recorded appearance was in late August-September 1107, when he left for Normandy with the king. There is an exhaustive study of this man in K.S.B. Keats-Rohan, 'Domesday Booke and the Malets', Nottingham Medieval Studies xli (1997), 13-51, where it is suggested that Robert was twice married, once to a daughter of Hugh de Montfort, that he was father of William II Malet, who forfeited Eye in 1110, and of Robert Malet (q.v.), ancestor of the Malets of Curry Malet, Somerset, and that he may have died as a monk of Bec after 1107.
