ROBERT de Vermandois, son of HERIBERT [II] Comte de Vermandois & his wife Adela [Capet] (-after 19 Jun 966). "Rodberti filium Heriberti comitis" witnessed a charter of "Gauzfredus comes" dated Jul 940[1356]. Under the division of the territories organised subsequent to his father's death in 943, Robert became Comte de Meaux. He became Comte de Troyes in 956 on the death of his father-in-law, by right of his wife. Richer names "Robertus Trecarum princeps, Heriberti tiranni filius, Hugonis vero abdicate frater" when recording his rebellion against King Lothaire and capture of Dijon in 959[1357]. The Chronicon Sancti Petri Vivi Senonensis records that "Rotbertum comitem" expelled "Ansegisum Trecarum Episcopus" who sought refuge "in Saxoniam ad Ottonem Imperatorem", dated to 959[1358]. Otto I King of Germany sent his son Bruno to besiege Troyes, and King Lothar attacked Dijon which capitulated in 960[1359]. "Gaufridus…Andecavorum comes" issued a charter dated 19 Jun 966 subscribed by "Roberti comitis Trecassinorum…"[1360].
m (before 950) [as her first husband,] ADELAIS [Wera], daughter of GISELBERT Duc des Bourguignons, Comte de Chalon-sur-Saône et de Troyes & his wife Ermengardis [de Dijon] ([930/35]-after Aug 967). "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"[1361]. The Chronicle of Saint-Bénigne de Dijon records the death in 956 of "Gislebertus comes Burgundionum", names "filia Leudegarde" and "aliam…filiam…Werram", and the latter's marriage to "Robertus comes Trecassinorum"[1362]. It is unclear why these two sources refer to the wife of Comte Robert by different names, as "Adelais comitisse" who signed the 959 charter must have been the same person as the wife of Robert named in 956 because the former document also refers to "Erberti filii eorum". It is possible that the reference to "Werram" is a transcription error as no other reference to this name has so far been found in other contemporary French sources. Her birth date range is estimated from her own daughter's estimated birth date of [950].
