Ermentrude of Roucy

Ermentrude de Roucy (c. 951 – 5 May 1005) (Irmtrude) was a Countess and Duchess of Burgundy.

She was a daughter of Renaud of Roucy and his wife, Alberade of Lorraine, daughter of Gilbert, Duke of Lorraine.

By 971, Ermentrude married Aubry II of Mâcon and thus became a countess of Mâcon. They were the parents of:


 * Létaud, archbishop of Besançon;
 * Aubry, abbot of Saint-Paul de Besançon;
 * Béatrice de Mâcon (d.1030), who was married in 975 to Count Geoffrey I of Gâtinais, and afterwards to the Count Hugues du Perche;
 * Perhaps a daughter, N de Mâcon, the putative spouse of Eble de Poitiers, son of William IV of Aquitaine and Emma of Blois; they were possibly the parents of Ebles I of Roucy and all of his siblings, including Yvette de Roucy, the wife of either Manasses II or Manasses III of Rethel.

She also married Otto-William, Count of Burgundy. They had children:
 * Guy I of Mâcon;
 * Matilda, married Landri of Nevers;
 * Gerberga, married William II of Provence;
 * Reginald I, Count of Burgundy;
 * Agnes of Burgundy, Duchess of Aquitaine.
