Merlet and Clerval suggest that Hugues [I] was the brother of Vidame Albert, although emphasise that no proof of this hypothesis exists[670]. According to the genealogical table inserted by Lépinois and Merlet in their introduction to the cartulary of Notre-Dame de Chartres, Hugues was the son of "Nivelon" brother of Vidame Albert, but no sources are cited[671]. It appears that this supposed connection is completely speculative, based on the charter dated 1033, under which Geoffroy II "Martel" Comte d´Anjou bought "molendinum...prope ecclesiam Sancti-Martini" from "Erfredo Ruffo...milite Burchardis senioris de Charismot", which was subscribed by "...Nivelo de Carnoto..."[672]. It is possible that the subscriber was the same person as Nivelon [I] Seigneur de Fréteval, from which appears to have arisen the tradition that the seigneurs de Fréteval and the vidame de Chartres were descended from the same family. No primary source evidence has been found which indicates that this might be correct.
