Halenald de Bidun

Halenald de Bidun or Halneth de Bidun was a Breton who held land in England during the reigns of King Henry I and Stephen.

Halenald was from either Bidon or La Ville-Bidon, two locations in the Dol region of Brittany. By the late 1120s, he was overlord of a group of manors around Lavendon in Buckinghamshire. The lands were held in 1086 by William, who was the chamberlain of Geoffrey de Montbray, the Bishop of Coutances, when they were recorded in the Domesday Book as William's. The historian I. J. Sanders considered the honour of Lavendon as probably an English feudal barony, which if true would make Halenald the Baron of Lavendon. However, Katharine Keats-Rohan concluded the chronology of this reconstruction was faulty and instead sees Agnes, daughter of John fitzPayn as the wife of a younger Halenald de Bidun, the elder Halenald's son, while attributing unknown parentage to the latter's second wife Agnes. Halenald had at least one daughter, Amicia and perhaps another named Matilda, who may have been the daughter of John de Bidun, however. Besides John, it is not clear which of his wives was the mother of his various children. Halenald died after 1156, and his widow survived him. Amicia married Gerard de Limesi, and Matilda married Walchelin Visdeloup, and was a widow in 1185.
