In 1164 the sheriff of the county accounted for him into the exchequer for 75s, 10d. And in the next year he himself certified that he held in capite of the King four knights' fees in Northumberland. In the 16th year of same reign he accounted for 20 marks, imposed upon him as a fine for his horses being taken in the King's forest. In 1172 he paid 4 pounds for scutage. He died 1188 and was buried near his father in Newminster. He married Alice de Stutteville, daughter of Roger de Stutteville of Burton Agnes, County York, great grandson of Robert de Stuttevile, who came into England with William the Conqueror. Her son Roger gave to the canons of Brinkburne certain commons of pasture for the good of her soul.
