His parentage is confirmed by the charter dated to [1040/44] under which "Guanilo thesaurarius Sancti Martino" donated "ecclesiam juxta Montiniacum castrum meum", for the souls of "Ratherii de Montiniaco et Hugonis filii eius", with the consent of "Nihardus de Monte Aureo nepos meus…". A charter dated 1059 and 1063 records the consent given by "Nihardus", previously withheld, to the payment to "Guarino fratri hujus Hugonis" relating to the purchase of “Longa-Ulmus” [Lancôme] by the abbey of La Trinité de Vendôme, the charter dated 5 Dec 1059 concerning the original purchase excepting “una causa Alberici de Monte-Aureo senioris sui”. A charter dated 5 Dec 1059 records the sale to La Trinité de Vendôme of "ecclesiam...Longa-Ulmus", held by "Hugo Theodelini filius" from "Nihardi de Monte-Aureo", and notes that after the death of "Nihardi" he was succeeded “in honorem” by “Alberico...cum filia eius” whom he had married.
The name of Nihard’s wife is not known. 1
