Research Notes:

Père Anselme states that the wife of "Gilbert Comte de Reims et de Roucy…semble avoir été de la maison de Poitiers" and that the couple were parents of Ebles, Liétard and Judith... The primary source on which this is based is not known. However, it is doubtful whether it can be correct in all its details. In particular, Judith Ctss de Rethel (alleged daughter of Giselbert & his wife...) must have been born in [1020/30] for chronological consistency with the estimated birth dates of her descendants, which excludes her being Giselbert's daughter. In addition, the origin of the names Ebles, Liétard and Judith is unclear among the family of Giselbert Comte de Roucy. Jean-Noël Mathieu suggests that Giselbert died childless and that the father of these children was Ebles de Poitou, son of Guillaume IV "Fier-à-Bras" Duke of Aquitaine [Guillaume II Comte de Poitou] & his wife Emma de Blois, based partly on onomastics and partly to explain how the territories of Rumigny-en-Porcéan and Coucy (under the suzerainty, respectively, of the abbey of Saint-Nicaise de Reims and the church of Saint-Rémi de Reims, and thereby closely connected with the family of the Comtes de Blois-Champagne) came into the family. J-N. Mathieu also suggests that the mother of these children was an otherwise unknown daughter of Ermentrude de Roucy, sister of Comte Giselbert, by her first husband Aubry [II] Comte de Macon who, in the ordinary course of events, would have been heiress of Roucy if Giselbert had died childless. The suggestion appears consistent from a chronological point of view. However, more research is needed to establish the original source on which the affiliation from Giselbert is based. Another possibility is that Ebles and Eudes were sons of Giselbert, but that Lietaud and Judith were children born from a second marriage of their mother. ¹
