William de Peveral is usually said to be an illegitimate son of the Conqueror. He had at least four children, William, d. s. p., and William again, who succeeded him, and two daughters, Maud and Adelise, the wife of Richard Redvers. The Conqueror gave William Peveral the custody of Notts Castle, when it was built in 1068, and extensive possessions, afterwards known as the honour of Peveral, consisting of 100 lordships in counties Notts and Northants, 14 in Derby, and some 20 others in other counties. William Peveral died Jan., 1113.
