Hugh the Black
Hugh the Black( died 952) was Duke of Burgundy from 923 until his death in 952.
He was a Bosonid through his father, who was the younger brother of Boso of Provence.
Hugh was the son of Richard of Autun, Duke of Burgundy, and Adelaide of Auxerre.
He succeeded his older brother Rudolph as Duke of Burgundy, when Rudolph was elected King of West Francia, as Raoul, in 923.
Following Raoul's death in 936, Hugh may have had aspirations to follow his brother onto the throne and refused to recognize Louis IV as king of West Francia.
As a result, Louis sent Hugh the Great who captured Auxerre and Sens.
The Duchy of Burgundy was divided between Hugh the Great and Hugh the Black.
It is unknown whether Hugh married.
He probably died without living offspring, as he was succeeded as Duke of Burgundy by Gilbert of Chalon, who held the title of Duke of Burgundy" jure uxoris", his wife Ermengard being the daughter of Richard of Autun, and sister of Hugh.
Alice of Vergy
Alice( or Alix) de Vergy( 1182–1252) was duchess consort of Burgundy as the second spouse of Odo III, Duke of Burgundy.
She was the regent of Burgundy during the minority of her son 1218 – 28.
Alice was the daughter of Hugh, Lord of Vergy, by Gillette de Trainel.
In 1199, she married Odo III, Duke of Burgundy.
Their children were:
Henry, son of Robert I of Burgundy
Henry of Burgundy (c. 1035 – January 27, 1070/1074), called the Gallant ("le Damoiseau"), was the eldest surviving son and heir of Robert I, Duke of Burgundy, second son of Robert II of France, and his wife, Helie of Semur, granddaughter of Henry I, Duke of Burgundy.
Little is known about his life.
He died shortly before his father and was never duke himself.
The name of Henry's wife is not known, though both Sibylla and Clémence have been suggested.
The first of these derives from an undated obituary from Besançon, Sainte-Etienne, naming "Sibilla, mater ducus Burgundie" (Sibylla, mother of the Duke of Burgundy), it being reasoned that since she is not called duchess, she must have been married to the sole father of a duke who was not a duke himself, Henry.
However, it has been argued by Jean Richard that this is a reference to Sibylla of Burgundy, Duchess of Burgundy, mother of the then-ruling duke, Hugh II.
Richard proposed based on the name's repeated use among the descendants of her son Odo I, Duke of Burgundy that she may have been named Clémence, although Odo's wife had a sister, Clementia of Burgundy, who could have been the inspiration for its use among their descendants.
Based on the use of the byname "Borel" by Odo I, genealogist Szabolcs de Vajay proposed that his mother was the daughter of Berenguer Ramon I, Count of Barcelona and his third wife, Guisle of Lluca, and hence granddaughter of Ramon Borrell, Count of Barcelona, although there is no documentary evidence that this was the case.
Henry's wife died on or after July 6, 1074.
Sibylla of Burgundy
Sibylla of Burgundy( 1126 – 16 September 1150 in Salerno) was the second queen consort of Roger II of Sicily.
She was a daughter of Hugh II, Duke of Burgundy, and his wife Felicia- Matilda of Mayenne.
In 1150, Sibylla married King Roger II of Sicily.
On 29 August of that year, Sibylla gave birth to a stillborn child and died of complications of the childbirth.
She was buried in the church of the Monastery of La Trinità Cava de' Tirreni.
Odo I, Duke of Burgundy
Odo I (1060 – 1102), also known as Eudes, surnamed Borel and called "the Red", was duke of Burgundy between 1079 and 1103.
Odo was the second son of Henry of Burgundy and grandson of Robert I.
He became the duke following the abdication of his older brother, Hugh I, who retired to become a Benedictine monk at Cluny.
He participated in the French expedition to the Iberian peninsula, started after the Battle of Sagrajas and ending with little accomplished in the failed Siege of Tudela in 1087.
Later, he participated in the Crusade of 1101, where he died, while in Asia Minor, in 1101.
In a charter from his expedition to the Iberian peninsula, he admitted he had withheld property belonging to the abbey of Saint-Philibert de Tournus, an abbey patronized by his aunt Constance, wife of Alfonso VI of León and Castile.
In 1101, when leaving on crusade, he made a gift and a will in favor of the abbey of Molesme.
Also when leaving on crusade, he signed a charter of renunciation at St. Beningne de Dijon and another at the priory of Gevrey-Chambertin.
An interesting incident is reported of Odo by an eyewitness, Eadmer, biographer of Anselm of Canterbury.
While Saint Anselm was progressing through Odo's territory on his way to Rome in 1097, the bandit, expecting great treasure in the archbishop's retinue, prepared to ambush and loot it.
Coming upon the prelate's train, the duke asked for the archbishop, whom they had not found.
Anselm promptly came forward and took the duke by surprise, saying "My lord duke, suffer me to embrace thee.
"
The flabbergasted duke immediately allowed the bishop to embrace him and offered himself as Anselm's humble servant.
