The Historiæ Andegavensis names "Goffridi de Castro Landono et Ermengardis filia Fulconis Comitis Andegavensis" as parents of "Fulco comes Andegavensis". Considering that she gave birth to children by her second marriage, it is unlikely that Ermengarde was born earlier than . She must therefore have been considerably younger than her brother. Her second marriage is deduced from a genealogy of the Comtes d'Anjou which names "Fulco (pater) Gosfridus et Ermengardis (mater) Gosfridus (et) Fulco (et) Hildegardis, de altero patre, filia Roberti ducis fratris Henrici regis". Her second marriage is dated from the letter written before  by Jean Abbot of Fécamp to Pope Leo IX recording that "Tedbaldo comite et Burgundionum…duce R" had "abdicatis legitimi thori connumbiis" and had "in inhonestis et consanguinitate fœdatis thalamis".
The necrology of Molesme records the death "XV Kal Apr" of "Robertus dux Burgundie et Ermengardis uxor eius". This entry suggests that Ermengarde died on the same day as her husband, possibly at the same place and in the same circumstances, although it is not infrequent for medieval necrologies to record couples on the same day, maybe in commemoration of a joint donation to the religious institution in question. 1
Ermengarde married Cte Geoffroy II "Ferréol" DE CHÂTEAU-LANDON et de Gâtinais, son of Hugues DU PERCHE, comte de Gâtinais, and Béatrix DE MÂCON, comtesse de Gâtinais, about 1035. (Geoffroy II "Ferréol" DE CHÂTEAU-LANDON was born about 1000 and died on 1 Apr 1046.
Ermengarde also married Duc Robert I "Le Vieux" DE BOURGOGNE, son of Robert II "Le Pieux" CAPET, King of the Franks, and Constance D' ARLES, Queen of France, about 1048. (Robert I "Le Vieux" DE BOURGOGNE was born in 1011 in France, died on 21 Mar 1075/6 in Fleury-sur-Ouche, Ome, Normandie, France.)
