'One of the most crucial figures of the frontier between León and Castile' (del Amo Lobo): a Leonese tenant at Villalobos in the Tierra de Campos who also inherited, through the Osorio line, rights in Aguilar de Campoo, its alfoz, Santullán and Valderredible, which he sold to the abbey of Aguilar in 1212.

Where the sources disagree
