ROBERT de France, son of ROBERT II "le Pieux" King of France & his third wife Constance d'Arles .

The Historia Francorum names "Hugonem qui cognominatus est Magnus, Henricum, Robertum, Odonem" as the four sons of King Robert and his wife Constance[110]. Rodulfus Glauber names "Heinricus rex…germanium suum Rotbertum" when recording the latter's installation as duke of Burgundy by his brother[111].

His mother supported him as candidate to be consecrated associate king in 1027, in place of his older brother Henri who was supported by their father. His father named him heir to the duchy of Burgundy in 1030. He was installed as ROBERT I Duke of Burgundy in 1032 by his brother King Henri I.

Comte d'Auxerre in 1040, when he conquered the county after Hugues Bishop of Auxerre died in 1039. He lost it after the 1060 council of Autun which ended his war with Nevers[112].

The necrology of Cîteaux records the death "VIII Id Mar" of "Robertus…dux Burgundie"[113]. The necrology of Molesme records the death "XV Kal Apr" of "Robertus dux Burgundie et Ermengardis uxor eius"[114].

m firstly HELIE de Semur, daughter of DALMAS [I] Seigneur de Semur-en-Brionnais & his wife Aramburge --- .

"Robertus dux Burgundionum" confirmed the possessions of Cluny by charter dated [1040] subscribed by "Ilie uxoris eius"[115]. The marriage is dated by the charter dated to [1034], subscribed by "Roberti ducis et uxoris sue", under which "Gibuinus" confirmed a donation to Saint-Etienne de Dijon[116]. "Robertus…dux et rector inferioris Burgundiæ" donated property to Saint-Bénigne-de-Dijon by charter dated 1 Mar 1043 which names "Helie uxoris mee…"[117].

Her origin is confirmed by the Vita S Hugonis, which records that "Dux Burgundie, gener eius" killed the father of St Hugues by his own hand[118].

The "Notes historiques sur le prieuré de Marcigny", included in the cartulary of Marcigny-sur-Loire, name "sancti Hugonis abbatis Cluniacensis et Gaufredi Sinemurensis, Andræ levitæ, Joceranni et Dalmatii, et sororum eorundem…Materdis, Adalaidæ et Cecilæ atque Evellæ" as children of "Dalmatius", but do not make the link with Duke Robert[119]. "Robertus dux et uxor sua Hylia" donated money to the church of Saint-Etienne de Dijon by undated charter[120].

She was repudiated, presumably on grounds of consanguinity, before [1050] when Jean de Fécamp wrote to Pope Leo IX reporting the second marriage of Duke Robert[121]. She became a nun as PETRONILLE after her repudiation[122].

The necrology of Auxerre cathedral records the death 22 Apr of "Helya uxor Rotberti ducis"[123].

m secondly as her second husband, ERMENGARDE [Blanche] d'Anjou, widow of GEOFFROY II "Ferréol" Seigneur de Château-Landon, Comte de Gâtinais, daughter of FOULQUES III "Nerra/the Black" Comte d’Anjou & his second wife Hildegarde de Metz .

The Historiæ Andegavensis names "Goffridi de Castro Landono et Ermengardis filia Fulconis Comitis Andegavensis" as parents of "Fulco comes Andegavensis"[124].

Her second marriage is deduced from a genealogy of the Comtes d'Anjou which names "Fulco Gosfridus et Ermengardis Gosfridus Fulco Hildegardis, de altero patre, filia Roberti ducis fratris Henrici regis"[125].

The necrology of Molesme records the death "XV Kal Apr" of "Robertus dux Burgundie et Ermengardis uxor eius"[126]. She was murdered with her husband.

http://en.wikipedia.org/wiki/Robert_I,_Duke_of_Burgundy

Robert I Capet was duke of Burgundy between 1032 to his death. Robert was son of King Robert II of France and brother of Henry I.
In 1025, with the death of his eldest brother Hugh Magnus, he and Henry rebelled against their father and defeated him, forcing him back to Paris. In 1031, after the death of his father the king, Robert participated in a rebellion against his brother, in which he was supported by his mother, Queen Constance d'Arles. Peace was only achieved when Robert was given Burgundy .
Throughout his reign, he was little more than a robber baron who had no control over his own vassals, whose estates he often plundered, especially those of the Church. He seized the income of the diocese of Autun and the wine of the canons of Dijon. He burgled the abbey of St-Germain at Auxerre. In 1055, he repudiated his wife, Helie of Semur, and assassinated her brother Joceran and murdered her father, his father-in-law, Lord Dalmace I of Semur, with his own hands. In that same year, the bishop of Langres, Harduoin, refused to dedicate the church of Sennecy so as not "to be exposed to the violence of the duke."
His first son, Hugh, died in battle at a young age and his second son, Henry, also predeceased him. He was succeeded by Henry's eldest son, his grandson, Hugh I.
