The names of a few priors have survived. It is not quite clear whether a certain Robert, whose name appears as witness to the deed by which Robert, Abbot of Mont St. Michel, during a visit which he made to the island in 1156, appointed Guillaume Gavin, monk, to the chaplaincy of St. George, was Prior of the Vale or not. He is styled in the deed Priest and Dean of the Vale (de Walo). In 1249 Henry, Canon of Blanchelande, was collated to the Vale Church by special dispensation. About 1307 Johannes de Porta was prior (probably a Du Port, a family of considerable antiquity in the island, and of good standing). In 1312 Guillaume Le Feivre filled the office. In 1323 Renauld Pastey was Prior of the Vale, and had a lawsuit with the inhabitants of that and other parishes concerning tithes. In 1331 there was another dispute concerning tithes, which was referred to the arbitration of two monks, Guillaume Le Feivre and Jourdain Poingdestre, who had both formerly been priors. In the year 1335 Andreas de Porta, 1364-68, Geoffrey de Carteret, and in 1365 Denis Le Marchant, clerk, was appointed seneschal of the Court of St. Michel. According to the ballad known as “La Descente des Arragousais,” “Brégard”[84] was the monk in charge of the priory in 1372, and by his intrigues the Vale Castle fell into the hands of the enemy, which was evidently a legend current at the time. Guillaume Paul, alias Règne, in 1478, is the last prior of whom we have found mention. The Priory of Lihou, as has been already said, was a dependency of St. Michel-du-Valle. The ruins of the church and other buildings are still to be seen. The former was entire at a time long subsequent to the Reformation, and is said to have been destroyed at the command of one of our Governors to prevent the possibility of its serving as an entrenchment in case of an enemy landing on the islet. It appears to have replaced a still more ancient building, as many pieces of Caen stone, with well-executed Norman mouldings, are built into the walls. Probably the first building had been destroyed in some of the many inroads to which the island was subjected during the reign of Edward III. An incumbent of Lihou, with the title of prior, existed until the time of the Reformation.
