Traditionally, he succeeded his father Nigel as baron of Halton and Constable of Chester, although modern sources doubt the position was held by his father. He held lands in Halton, throughout Cheshire and also in Normandy. Through his heiress mother he obtained Widnes and the Lancashire manors of Widnes, Appleton, Cronton and Rainhill. In 1115 he established Runcorn Priory, of the Augustinian Order of Canons Regular. He died in 1134 at Halton Castle and was buried at Chester. Marriage and issue
