Pelayo and his father are usually associated with the party that supported Sancho I and his son Ramiro III. Their chief rival clan was led, during Pelayo's episcopate, by Gonzalo Menéndez, who supported first Ordoño III, later his son Vermudo II. García Álvarez credits fear of retribution from Gonzalo with forcing Pelayo into exile in Celanova. The rivalry between the two families, however, had more to do with a dispute between Gonzalo's mother, Mummadomna, abbess of Guimarães, and a relative of Pelayo's, Guntroda, abbess of Pazóo.Guntroda was a sister-in-law of Pelayo's uncle, Ordoño Velázquez. Gonzalo defeated Rodrigo at the Battle of Aguiuncias, but the two were eventually reconciled. The resulting bad blood is alluded to as late as 1 October 982.Martín, 472 n38.
