Ermengarde-Blanche of Anjou
After her husband Geoffrey died Ermengarde-Blanche married Robert I Capet, Duke of Burgundy. Robert was the son of King Robert II of France. Because both Ermengarde and her second husband Robert Capet were both descendants of Ingelger, they were related by blood. This was found in charts prepared at the monastery of Saint-Aubin at Angers between 1048 and 1052. The ancestral charts show how closely the Angevin and Capet families were related. The charts were probably created over concerns of who Ermengarde and Robert's daughter Hildegarde could or could not marry. Ermengarde-Blanche died at Fleury-sur-Ouche on 18 March 1076. Robert died three days later at the same place on 21 March 1076.
