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.
Florine of Burgundy
Florine of Burgundy( 1083–1097) was a French crusader.

Children:
Philip I, Count of Auvergne
Philip of Burgundy (November 10, 1323 – August 10, 1346) was Count of Auvergne and Boulogne (as Philip I) in right of his wife and was the only son and heir of Odo IV, Duke of Burgundy, and of Joan III, Countess of Burgundy.
His mother was the daughter of King Philip V of France and of Joan II, Countess of Burgundy.
He married Joan I, Countess of Auvergne and Boulogne, in c. 1338.
In 1340, he fought with his father who defended the city of Saint-Omer against the assaults of Robert III of Artois.
In 1346, he participated in the siege of Aiguillon, led by John, Duke of Normandy (the future John II of France).
It was during this siege that he died, after falling from his horse.
His widow Joan remarried in 1349, her second husband being King John II of France.
Since Philip had no other sons from his marriage to Joan, the future of the House of Burgundy was then placed in the hands of his young son Philip (1346–61), who died childless.
After the death of the younger Philip, the dukedom of Burgundy became a part of the French crown, and was granted by John II of France to his youngest son (and the previous Duke’s stepbrother), Philip the Bold.
His daughter, Joan (134411 September 1360), was betrothed to Amadeus VI, Count of Savoy from 1347 to 1355, and was raised at his court.
When she was released from the engagement at age 10, she entered a convent at Poissy, where she remained for her final years.

In 1346 and 1347, she was an influence at the court of her nephew, Amadeus VI to pursue closer alliances with Burgundy to offset the pending sale of the Dauphiné to France.
