Arnau Guillem I, IV vescomte de Fenollet

After Arnau Guillem I, the vicounty will go temporarily over to another family. In 1086, count Bernat II de Besalú offers the castell de Fenollet to Bernat Torró senyor de Maurí, and shortly after he offers the vicounty de Fenollet to Guillem Bernat, son of Arsenda (which might be in the descendats of the Montesquiu). However, the vicounty of Fenollet comes back to the family with Arnau Guillem I's son, Arnau Guillem II.
