Hildegarde of Burgundy Wikipedia
Hildegarde of Burgundy (c. 1056–1104) was a French noble, 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. She was, and by marriage, Duchess of Gascony and Aquitaine.
She married William VIII, Duke of Aquitaine; she was his third wife. William and Hildegarde had these children together:William IX, Duke of Aquitaine
Agnes of Aquitaine, Queen of Aragon and Navarre
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.
