His son, Nicolas de la Roche, took over from him in 1398. In 1404, he married Alix de Chauvigny, daughter of Chateau Rocher's lord. Their oldest son, Jean de La Roche, married Louise de La Fayette (daughter of Marshal Gilbert Motier de La Fayette) in 1419 and inherited Tournoël subject to an usufruct. He was killed during the Battle of Verneuil in August 1424 at the age of 22. He was survived by three children. When Nicolas died in 1428, his other sons claimed the property of Tournoël from Jean's widow.
