Isabelle DE THIERN
The necrology of Beaune records the death "XVII Kal Jul" of "Ysabel comitissa et uxor Hugonis fratris ducis Burgundie". Her parentage is confirmed by the charter dated 1186 under which her son "Guillelmus Cabilonensis" confirmed a donation to Ferté-sur-Grosne made by "pater eius Huo et avunculus eius atque avus, comites Cabilonenses".
Isabelle married Hugues "le Roux" DE BOURGOGNE Seigneur du Châtelet-Chalon et de Meursault, son of Hugues II Borel DE BOURGOGNE Duke of Burgundy and Mathilde (Maud) DE MAYENNE, about 1149. (Hugues "le Roux" DE BOURGOGNE Seigneur du Châtelet-Chalon et de Meursault was born in 1121 and died on 23 Apr 1171.)
