"Drocho de Merloto miles et...Willelmus filius eius" attested a donation to Saint-Germain made by "D. uxor Hugonis militis de Chevannis" by charter dated Apr 1208[232]. "Droco de Merloto senior", on the point of leaving for Jerusalem "apud domum suam de Belca" {Beauche} in the presence of "filiis suis Willelmo et Drocone juniore", recorded that the men of Saint-Maurice did not have the right to use the wood of Saint-Aubin-Château-Neuf by charter dated 1216[233]. Seigneur de Saint-Bris. "Guillaume de Mello seigneur de Saint-Bris" granted vine cultivation rights to the monks of Reigny, with the consent of "Elisabeth sa femme", by charter dated 1216[234]. A charter dated 1223 records judgment in a dispute between the abbey of Sens-Saint-Rémy and "Droconem de Melloto dominum Lochiarum" concerning certain serfs, with "Willelmo de Melloto fratre suo" acting as guarantor[235]. "Guillelmus dominus de Merloto, Milo dominus Noeriorum, et Droco dominus de Espoisse et Chatel-Chinun" certified that "Gaucherium de S.-Florentino armigerum...concedente Eustagia uxore sua" had renounced rights in favour of Pontigny by charter dated May 1240[236].

"Guillaumes de Mellot sires de Saint-Briz" swore hommage to Thibaut King of Navarre, Comte de Champagne for revenue from "la foire de Bar-seur-Aube" by charter dated Jan 1242 (O.S.)[238].
m ELISABETH, daughter of --- (-after 1216). "Guillaume de Mello seigneur de Saint-Bris" granted vine cultivation rights to the monks of Reigny, with the consent of "Elisabeth sa femme", by charter dated 1216[239]. The Gesta Episcoporum Virdunensium (Continuatio) records the succession of "Guido de Melloto" as bishop of Auxerre, naming his parents "pater...Guillelmus de Melloto miles dominus castri Sancti Prisci...mater eius de prosapia dominorum Montis Sancti Iohannis"[240]. No connection with the family of the seigneurs de Mont-Saint-Jean (see below) has yet been established. The chronology of the marriages of her grandchildren suggests that her children must have been born well into the 13th century, in turn suggesting that Elisabeth was considerably younger than her husband. If that is correct, she may have been his second wife.
Guillaume & his wife had five children
