The Chronicon Regum Legionensium names "Elvira" daughter of "count Menendo González and his wife countess Mayor" as the wife of King Alfonso. Her parentage is confirmed by the charter dated 15 Nov 1028 under which her son "Ueremudus proles Adefonsi principis et Geluire regine" donated "villam meam…Cordario que fuit avorum et parentum meorum Menendi et dne Tote" to Santiago de Compostela.
The Chronicon Regum Legionensium records that King Alfonso was buried in León "with his wife Elvira". The Chronicon del Salterio, dated to 1055, records the death "IV f[eri]a M i[u]l[i]o era TLXVI" of "Adefonsus rex" and "uxor eius Gelbire IV N[ona]s Dec era TLX". 1
