Ermengarde of Anjou, Duchess of Burgundy

Ermengarde of Anjou (c. 1018 – 18 March 1076), known as Blanche, was a Duchess consort of Burgundy. She was the daughter of Count Fulk III of Anjou and Hildegarde of Sundgau.[1] She was sometimes known as Ermengarde-Blanche.

She married Geoffrey II, Count of Gâtinais c. 1035 (in French Geoffroy), called Ferréol and sometimes known as Aubri, seigneur de Château-Landon.[2] Together they had three children:

• Hildegarde de Château-Landon, married c.1060[3] to Joscelin I, Lord of Courtenay[2]
• Geoffrey III, Count of Anjou[2]
• Fulk IV, Count of Anjou[2]

Geoffrey II died sometime between 1043 and 1046, and Ermengarde's mother died while on pilgrimage to Jerusalem in 1046.

She married Robert I, Duke of Burgundy in 1046, conferring on her the title Duchess of Burgundy.[4] Together they had one daughter:

• Hildegarde, (c. 1056–1104),[5] who married Duke William VIII of Aquitaine in around 1067[4]

Ermengarde was murdered on the 18th of March, 1076, at the Church of Fleurey-sur-Ouche, three days before her 58th birthday.[6]
