Payne's Armorial of Jersey is correct in stating that both de Barentins held the office, but has the timings wrong. Drew was too young to have held office in 1258 and was not appointed until 1309. During his period of office he was assisted by Pierre de Petitfeu. De Barentin was killed defending Mont Orgueil Castle during a French attack.
From Payne's Armorial of Jersey by J Bertrand Payne
At what precise time this family quitted Normandy, where it had attained to distinction from the earliest historic period of that duchy, is not certain. It appears that previous to its emigration it was settled near, and took its name from, the village of Barentin, near Rouen. The first mention made of the name in England, is in the person of Alexander de Barentin, who is stated by Brayley, in his "History of Surrey", to have been baker to Henry II, circa 1160, and to whom the King gave much land in Cavcham or Cobham.
Shortly before the year 1220, Drew, Duit, Drocus, Drogo, or Drouet De Barentine, obtained, through circumstanccs upon which history throws no light, the important Seigneurie of Rozel and, in 1367, his descendants were possessed of extensive and valuable estates in Jersey, consisting of the manors and lordships of Rozel, Samares, Longueville, Dielament, and Les Augres.
Upon the authority of notes appended to the record of a lawsuit, that attended the eventual transfer of this property, it has generally been alleged that these large possessions wore bestowed, as a free gift, by the King upon this eminent person—part or all of it having escheated to the Crown, by the adherence of Engelramus de Fournet, Seigneur of Rozel, to the French monarch, at the period of the revolt of the Normans. But, as this same De Fournet appears in a Liberate Roll of Henry III, as having been at that period in the King's service, it may, with greater probability, be surmised that part, if not all, of the property, was acquired by purchase.
Owing to his influential position. Drew de Barentine was constituted Warden or Governor of the Norman Isles in 1220. Although their names have not reached us, it appears probable he, at some period, governed by deputies, for in 1223 he is mentioned as having been in the King's service in Wales, and in 1225-6 he served among the English knights in Gascony. In 1230 he held, with Jane his wife, the manor of Cheveres, in Norfolk, in which year he was granted a weekly market, and a fair yearly, with free warren on his demesne lands there.
In 1239, being very aged, he appears as being accredited ambassador to Rome. He was succeeded in his English and Jersey estates by his son, William De Barentine, who died young, and who founded a chapel and hospital for lepers at Cheveres, and gave considerable lands and part of his lordship to endow them. His son, Drew De Barentine, was Governor of the Scilly Isles in 1251, and shortly afterwards held the same dignity in the Norman islands; vested with which, he was slain in 1253, in a gallant defence of the Castle of Mont Orgueil from an attack made on it by the French. Dying without issue, his estates were inherited by his nephew William, of whom presently. He appears to have had other relatives, not mentioned in the pedigree, among whom were Henry, who is mentioned with Eleanor his wife, of the county of Essex, in 1271 ; Stephen, with Matilda his wife, also of the county of Essex, in 1248 ; Drew, who was Seneschal of Gascony in 1260, and in 1264 was Constable of Windsor Castle, and who, by an Issue Roll of 61 Henry III, is paid for "going as the Queen's Messenger beyond the seas, 30 marks for his expenses ; " and in the same year is paid " £10 for palfreys, sumpter-horses, and harness for his two nephews, whom the King, in Gascony, decorated with the belt of a knight."
Thomas de Hamptonne
Thomas de Hamptonne may have briefly been appointed Warden in 1313. The only reference to him as Warden is in Payne's Armorial. If his name has been correctly spelt he would be a member of the de Hamptonne family of Jersey and possibly a local person appointed lieutenant to Lord of the Isles Otto de Grandison
Henri de Sully
The appointment of de Sully as Warden is a strange one. First of all he was French, and secondly he appears to have died before being able to take office.
Henri, born in 1282 in Sully, Berry, France, was Seigneur de Sully when, by letters patent of 9 June 1323 Edward II appointed him Warden from the time when the islands reverted to the King on the death of Lord of the Isles Otto de Grandison. However, the appointment never took effect and it is assumed that by the time de Grandison died in 1328, de Sully was already dead.
Gérard Derous
Derous (1323-1326) was appointed to look after the Channel Islands by Lord of the Isles Otto de Grandison, but whether present or not, he did not appear to be functioning to the satisfaction of King Edward II in the early years of his appointment because the King sent Jean de Clyvedon as Warden. Clyvedon told him that no special warden was required because de Grandison had appointed Derous. There were complaints against Derous during his period of office by the Abbot and monks of Mont St Michel.
He first visited the islands as an itinerant justice in 1323. His actual name is far from certain, appearing as Gérard Derous, Dorme, Oronis or de Evrons. He is mentioned in Ancient petitions of the Chancery and the Exchequer relating to the Channel Islands and kept at the Public Record Office in London, as having been de Grandison's lieutenant from 1321 to 1328.
Jean de Clyvedon
De Clyvedon is shown as Warden from 1234 to 1235, buty may have been appointed earlier. He was appointed by the King because of the "negligence" of Lord of the Isles Otto de Grandison and in 1325 he was discharged having requested his release because he said that the islands had no need of a special Warden because Otto had appointed Gerard Dorme as his lieutenant. This was probably Girart Derous, who is shown as Warden in some lists from 1323-1331.
