William Devereux (1219 to 1265) was an important Marcher Lord and held Lyonshall Castle controlling a strategically vital approach to the border of Wales. The castle’s significance was heightened by the rebellion of Llywelyn ap Gruffudd Prince of Wales. With strong family ties to the politically powerful families of Cantilupe and Giffard his support was strongly sought after by Henry III and Simon de Montfort throughout the Second Barons’ War.
