Diogo Fernandes (count)

Diogo Fernandes (died before 1 December 928),[1] (Spanish: Diego Fernández) was a count in the Kingdom of León whose filiation has not been documented although, from his patronymic, it is known that his father was named Fernando,[2] and that he was possibly from Castile.

[1] Diogo arrived at the county of Portugal near the end of the 9th century, accompanying, according to Sampiro, Infante Bermudo Ordóñez, the son of Ordoño I of Asturias, who after rebelling against his brother King Alfonso III, fled to Coimbra where he lived and died shortly before 928.

[7] Count Diego appears for the first time in medieval charters on 28 April 909, confirming a donation made by King Alfonso III.

[8] He accompanied King Ramiro II when he established his court in Viseu and his last appearance was on 23 February 926 when he confirmed a donation made by this monarch to Hermenegildo González and his wife Mumadona, Diogo's daughter.

Taken together with her use of the name Leodegundia for a daughter, this led Pérez de Urbel to conclude that she was a member of the royal house of Pamplona, born to the infanta Leodegundia Ordóñez, thought to have been daughter of Ordoño I of Asturias and, as implied by a celebratory poem in the Códice de Roda, a bride in Pamplona.
