d) ALIX de Châtillon (-1235 or after). The Chronicle of Alberic de Trois-Fontaines names "Aleydem [uxor] marchionis Eystensis in Italia" as third of the three daughters of "Raynaldus de Castellione uxor…relictam principis Raymundi"[709], although it is chronologically unlikely that Alix could have been the daughter of Renaud by his first wife who died [1163/67]. Pope Innocent III confirmed his protection of "nobili mulieri Aliz, filiæ quondam principis Rainaldi" by charter dated 16 Jun 1198[710]. A charter dated 22 Feb 1204 records the marriage contract for "dominus Azo Estensis marchio" and "domina Aliz filia quondam Rainaldi principis Antiocheni"[711]. The testament of "dominus Azzo Estensis marchio", dated 18 Nov 1212, bequeathes property to "filie sue domine Beatrici…Aldeurandinum et Azzolinum novellum filios", a codicil naming "uxori mee domine Ailisii…filie mee Constantie"[712]. "Domini Azoni Estensis Marchionis" donated property to the monastery of Santa Maria at Carceres, with the consent of "Domina Adelice sua matre", by charter dated 1235[713].
