GUY de Brienne (-13 Feb ----). His parentage is confirmed by the charter dated to [1125 or before] in which "Airardus Breonensis comes…et comitem Barrensem Milonem fratrem suum" are named, subscribed by "Milonis comitis, Widonis filii eius"[146]. 1145. Comte de Bar-sur-Seine. The necrology of the abbey of Mores records the death "Pridie Id Feb" of "Guido comes Barrensis"[147]. m PETRONILLE-ELISABETH de Chacenay, daughter of ANSERIC [II] de Chacenay & his wife Humbeline [de Troyes] (-[28 Aug] ----). 1139/1165. The foundation charter of the abbey of Mores, undated but dated to 1152, records the donations of "Petronilla, Barri comitissa…pro anima viri sui Widonis et filiorum suorum Milonis et Willelmi"[148]. There is doubt about her name as the cartulary of Troyes Saint-Pierre records a charter dated [1148/53] which recalls a donation by "Helisabeth mater Milonis comitis Barensis et ipsius uxor Agnes"[149]. The primary source which confirms her parentage has not yet been identified. The necrology of Notre-Dame aux Nonnains records the death "28 Aug" of "Petronilla, monacha comitissa Barri"[150], although this entry could refer to her granddaughter. Comte Guy & his wife had six children
