Conflent, and the interior counties of Gothia that had previously been linked with Rosselló (Vallespir, Capcir, and Fenolleda), passed to Wilfred, and upon his death to Miro the Young.
He began his episcopate by reforming the cathedral canons, along the lines of the life of Saint Augustine of Hippo, and granting them land in Vallespir, Cerdanya, and Alt Urgell.
