Roger-Bernard's only son, Raymond Roger, accompanied the French king, Philip Augustus, to Palestine in 1190 and distinguished himself at the capture of Acre. He was afterwards engaged in the Albigensian Crusade defending the Cathars, and, on being accused of heresy, his lands were given to Simon de Montfort, 5th Earl of Leicester. Raymond Roger came to terms with the Church and recovered his estates before his death in 1223. He was a patron of the Provençal poets and a poet himself.
