Appearing in medieval charters from 1014 until 1017 when he confirms two diplomas issued by King Alfonso V of León, Ordoño spent his life in Asturias.
He died between 1017, the last time that he appears in the documentation, and before 31 March 1024, the date on which his wife Cristina, declaring herself a widow, makes a donation for the founding of the Monastery of Cornellana.
