Torbeno or Turbino was the eldest son and successor of Orzocorre I as Judge of Arborea from about 1100 until his death.
Torbeno himself married Anna de Lacon and was the father of Orzocorre II, who succeeded him.
Torbeno, with his son, signed a charter permitting his mother Nivata to dispose of the castles of Nuraghe Nigellu and Massone de Capras, which she had built, as she wished.
Torbeno's charters are subscribed by the curators of Oristano, Valenza, Milis, Fortoriani (Fordongianos), and Usellus.
The curator of Valenza was Comita of the powerful Lacon family to which Torbeno was related by marriage.
