Pérez de Urbel suggests that one of the daughters of Pelayo González was the mistress of Ordoño III King of León and the mother of King Vermudo II. He bases his argument on three charters. Firstly, King Vermudo donated property to the monastery of San Lorenzo de Carbonario, for the souls of “abii mei divæ memoriæ comes dominus Gundisalbus...et...uxori...coniuncta comitissa domina Tarasia”, by charter dated 5 Jan 999. The couple “comes dominus Gundisalbus...et...uxori...coniuncta comitissa domina Tarasia” are identified as Conde Gonzalo Betótiz and his wife Teresa Eriz, who lived in the late 9th/early 10th century and the birth of whose children is estimated to the early part of the 10th century... Yepes noted the couple as founders of San Lorenzo de Carboeiro by charter dated 936, although he does not cite the primary source. The chronology of Conde Gonzalo indicates that “abii” cannot in this document be interpreted in its strict sense of grandparents. However, if the word indicates more remote ancestry, it would be chronologically possible for King Vermudo´s mother to have been the granddaughter of Conde Gonzalo. Secondly, Pérez de Urbel cites the 973 charter quoted above which names the three sisters Gontroda, Aragonta and Teresa, all three nuns at that date. Thirdly, he discusses the charter dated 29 Jun 997 under which King Vermudo II donated property “ad Septentrione plaga, per latus, montis Villara...” to the monastery of San Vicente de Pombeiro, and confirmed donations made by “...amica [amita?] nostra domina Teresia...”, the document being subscribed by “...Teresia Deo dicata...”. He suggests that “Tarasia Deo uota” in the 973 charter was the same person as “[amita] nostra...Teresa...Teresia Deo dicata” in the 29 Jun 997 charter. In light of these three documents, Pérez de Urbel suggests that King Vermudo´s mother was a daughter of Pelayo González and his wife Ermesinda Gutiérrez.... 1
