During his career, he was steward of Gower, Chancellor of Glamorgan and constable for life of the Kenfig and Caerphilly castles. In the late 15th century the manor was refurbished and modified; It is believed that Mathew Cradock was responsible for the construction. His only child, Margaret, was heiress of the manor. Sir Richard Herbert married Margaret. He was from Ewyas, Hereford. In around 1500 alternations were made to the Hall range.
