No document of the era mentions the relationship between Gilbert and his successor Ebles I. It has long been thought that Ebles of Roucy was a son of Gilbert and of a daughter of William III, Duke of Poitiers.
A recent study[1] proposed another theory : Ebles I of Roucy was a son of Ebles of Poitiers (himself the son of William IV, Duke of Poitiers and of Emma of Blois) and of a daughter of Aubry II, count of Mâcon, and of Ermentrude of Roucy, sister of Gilbert of Roucy.
