The "Corónicas" Navarras name "la filla del Emperador dona Sancha" as the wife of "el rey don Alfonso d'Aragón". The Gestis Comitum Barcinonensium records the marriage of "Ildefonsus" and "Sanciam…filiam Imperatoris Magni Ildefonsi de Castellæ". Her name is confirmed in the charter dated 24 Feb 1212 under which Pedro II King of Aragon "filio Sanctiæ…Reginæ Aragonum" granted property to "Guillelmo de Montepessulano…filius Agnetis feminæ".
She founded the Hospitaller priory of nuns of Nuestra Señora at San Juan de Sijena in 1188, and became a nun there herself in 1197.
The Anales Toledanos record the death in 1208 of “la Reyna Doña Sancha Daragon, filla del Emperador” and her burial “en Sixena”. 1
