Hildegarde of Burgundy ¹

  General Notes:

Hildegarde of Burgundy (c.?1056\endash 1104) was a French noble,[1] Duchess consort of Gascony and Aquitaine by marriage to William VIII, Duke of Aquitaine.

She was the only daughter of Robert I, Duke of Burgundy with his second wife, Ermengarde of Anjou.[2] She was, and by marriage, Duchess of Gascony and Aquitaine.

She married William VIII, Duke of Aquitaine; she was his third wife.[3] William and Hildegarde had these children together:

William IX, Duke of Aquitaine
Agnes of Aquitaine, Queen of Aragon and Navarre
Beatrice?[4] married firstly to Alfonso VI of Leon and Castile and secondly to Elias I, Count of Maine.
William's birth was a cause of great celebration at the Aquitanian court, but the Church at first considered him illegitimate because of his parents' consanguinity. This obliged his father to make a pilgrimage to Rome soon after his birth to seek papal approval of his marriage to Hildegarde.

Hildegarde married Guy-Geoffrey "William VIII" VIII, Duke of Aquitaine, son of William V, Duke of Aquitaine and Agnes of Burgundy Duchess of Aquitaine and Countess of Anjou. (Guy-Geoffrey "William VIII" VIII, Duke of Aquitaine was born about 1025 and died on 25 Sep 1086 in Chizé, Nouvelle-Aquitaine, France.)
