HERIBERT [V] "le Jeune" ([945/50]-28 Jan 995 or 996, bur Abbaye de Lagny-en-Mussien). "Trecassine urbis comitem Robertum" donated land to "Gratianum abbatem monasterii Sancti Petri Dervensis" by charter dated 6 Aug 959, signed by "Adelais comitisse, Erberti filii eorum, Walterii vicecomitis"[1837]. He succeeded his father in 966 as Comte de Meaux et Comte de Troyes . It is assumed that Héribert [V] succeeded his paternal uncle Héribert [III] in [983/Apr 985], based on the following argument. A letter of Gerbert dated 983 records that "Heriberti Trecassini et Oddonis comitis filii Tedbaldi" were enemies of "Adelbero Remonis archiepiscopus"[1838]. However, a letter dated to Apr 985 names "Ottonis et Heriberti", while a letter dated to mid-985 records that "Ottonem, Heribertum" made peace with the archbishop[1839]. Another letter of Gerbert dated to [late 986/early 987] records that "O et Heribertus comites" were part of the council of Emma Queen of France[1840]. It is assumed that "Oddonis/Ottonem/O" all refer to the same person. However, it is suggested that only the first letter applies to Héribert [III], the change to Héribert [V] being indicated in the subsequent letters by "Heribertum" being named after "Ottonem" instead of before, which suggests that he was the junior of the two from Apr-985. On the death of his paternal uncle Héribert [III] "le Vieux", Lothaire King of France invested him with Epernay and le Perthois. He helped King Lothaire conquer Lotharingia, and imprisoned the comte de Verdun[1841]. m ---. 959. The name of Héribert's wife is not known. Bur suggests[1842] that she was a daughter of Etienne [Stephanus] Comte de Gévaudan & his second wife Adelais d'Anjou, basing his theory on the transmission of the name "Stephanus" to the couple's son. Héribert [V] & his wife had one child
