The Marcher lord of the Teme valley.
In 1195, with troops sent by Richard, he invaded Maelienydd and rebuilt the castle of Cymaron; in 1196 he and Hugh de Say were beaten by the Lord Rhys at Radnor, allegedly losing some forty knights (the figure as Wikipedia reports it from the chronicles). By 1200 he holds Maelienydd and that year grants a charter of liberties to the Welsh abbey of Cwm Hir. He also holds Saint-Victor-en-Caux in Normandy.
