"Henry was succeeded by his son Robert, who at Michaelmas, 1169, rendered account of 10 marks due by him to the aid to marry the king's daughter. His most notable act was the foundation of the priory of Burscough in or before 1189. He took part in the rebellion of his chief, John count of Mortain, in 1194, and later in the year paid an installment of the fine of 20 marks incurred therefor. He seems to have been married twice; his widow was Amabel daughter of Simon, who was suing her stepson for dower in 1199. Knowsley and Anglezark were subsequently assigned to her."
