A charter dated 23 Dec 927 records donations by “Gutier Menendiz comes…cum coniuge sua domna Ylduara” to the monastery of Santa María de Loyo, an interpolated document recording that “Ylduara cum filiis meis…Rudesindus episcopus, Munnio, Froila, Adosinda, Ermesinda” confirmed the donation for the soul of “nostro domno diue memoria domno Guttierre”. Her parentage is confirmed by the charter dated 11 Mar 934 under which “Rudesindus episcopus, Munionem, Froilanem, Adosinda et Ermesinda” (her children) agreed the division of territories inherited from “avorum nostrorum Hermegildi et Ermesinde, Eroni et Adosinde”. 1
