ROBERT MARMION, son and heir. All the land of Roger his grandfather and Robert his father was restored to him by Stephen. In 1155 he obtained from Henry ll a charter of freewarren in Warwickshire, especially at Tamworth, as his ancestors had had it in the time of Henry I, and after 1170 he had from King Henry-i.e. the eldest son of Henry II-a charter of free warren in all his land of Lindsey. In 1166 he was holding over 16 knights' fees. He granted Avon and Ditchampton, Wilts, and the honour of Llanstephan, co. Carmarthen, which had belonged to Roger his grandfather, to his uncle Geoffrey, in exchange for the latter's right in Winteringliam and Scrivelsby, co. Lincoln, and in the fee of Manasser Marmion. He granted the church of Checkenden, co. Oxford, to Coventry Priory, circa I170-75, in satisfaction of the injuries done to that house by his father; and, circa 1175-80, he granted a third part of Checkenden to Geoffrey Marmion, whose relationship is not specified. He began the foundation of Barbery Abbey in Normandy.
He is said to have married Elizabeth, whose parentage is unknown. He died in or before October 1181. [Completed Peerage VIII:508-9, XIV:468, (transcribed by Dave Utzinger)]
