Barons and castellans · Dauphiné of Viennois · as at first light, 1 January 1200

Clérieu

An old barony on the left bank of the Rhone between Romans and Tain: Clerieux, Chantemerle, Beaumont, Pont-de-l'Isere and the castle of La Roche-de-Glun, whose Rhone toll, said to rest on an imperial grant, made the family rich and later notorious.

Who he is

Family
Silvion and Roger are the lineage's recurring names; a Roger of Clerieu holds La Roche-de-Glun when Louis IX takes it in 1248. fr.wikipedia's page on Aymar II calls his wife Philippa of Fay 'lady of Clerieu', so part of the inheritance may already be hers.
