William d'Aubigny (died 1139)

In 1101 he was a witness to the treaty in which Robert II, Count of Flanders pledged military support to Henry and is named there as pincerna, evidence that he was one of the chief officers of the royal household.

At Old Buckenham, the first castle was probably built in his time, as was the nave of Wymondham Priory, now part of the parish church,[2] which he founded in 1107.

[4] He was also a benefactor to his father-in-law's foundation of Thetford Priory and, in Normandy, to the Benedictine abbey of Lessay that his father had supported.

[2] When Stephen became king in 1135, William initially retained his place at court, but had died by June 1139,[2] and was buried at Wymondham.

In or before 1107, William d'Aubigny, founded the Priory of Wymondham in Norfolk as a subordinate cell to the Monastery of St. Albans Abbey in Hertfordshire, and it continued as such until 1448, when it was converted into an independent abbey by a bull of Pope Nicholas V. Its original foundation occurred during the tenure of William's uncle, Richard d'Aubigny, Abbot of St. Albans from 1097 until his death in 1119.
