Othon Guillaume de Maçon Comte d'Bourgogne et Nevers
- Born: Abt 955-958, Lombardy, Italy
- Marriage: Ermentrude de Roucy Comtesse of Rheims
- Died: 21 Sep 1026-1027 about age 71
-Stuart's "Royalty For Commoners" (94:33) calls him King of Lombardy and Count of Burgundy and Macon. This is also the source for his 2nd marriage to Adélaïde/ Blanche of Anjou.
-Quoting from Christopher Cope's : "The Lost Kingdom of Burgundy":
"CONRAD was succeeded as King of Burgundy in 993 by his son Rudolph III. In 1006 the EMPORER HENRY II siezed Basel and extracted a promise from Rudolph to name him as his heir.
Rudolph was childless and HENRY was his oldest nephew; however the prospect was anethema in Burgundy to high and low alike, and when Otto William, the most powerful lord in the kingdom, raised the standard of revolt in 1016, many rallied to him; few Burgundians wished to be ruled by the alien Germans.
But Otto William was more than a folk hero, he was a man of high ambition. A contemporary wrote of him, 'Though nomially a vassal of the King of Burgundy, Otto William was resolved to be soverign master of his own territories.'
"Otto Willam, whose mother was Burgundian, was the son and grandson of the last 'national' kings of Italy, now ousted by the OTTONIAN EMPORERS. He was initially Count of Macon and Count of Burgundy, which means he held the lands north and west of the Jura known today as Franche Comte. In 1002 he was chosen by the bishops and barons of the area to succeed his stepfather [Henry I Capet as Duke of Burgundy, but he was expelled from the Duchy after a long conflict by the KING OF FRANCE, ROBERT CAPET. The latter's younger son, also ROBERT, became Duke of Burgundy, founding the junior branch of the Capetian dynasty. . . . "
"Unhappily Otto William divided his efforts between his ambitons in Italy and in Burgundy and was defeated in both - perhaps the first case of a Burgundian prince failing in Burgundy because of involvement in Italy. But he and his allies continued to defy Rudolph and to challenge HENRY's claims to the succession. Their efforts seemed rewarded when HENRY died in 1024, for his successor, CONRAD, THE FIRST FRANCONIAN EMPORER, had only a very distant claim of blood to the Burgundian throne. However, he had married one of Rudolph's nieces and in 1026 Otto William died, and so Rudolph set aside the rights of Rudolph's nephew and heir ODO OF BLOIS [aka EUDES II, COUNT OF BLOIS AND CHAMPAIGN] and on his death-bed in 1032 he sent Burgundy's regalia to CONRAD." 116
Othon married Ermentrude de Roucy Comtesse of Rheims, daughter of Renaud de Roucy Comte de Rheims & Roucy and Alberada de Lorraine. (Ermentrude de Roucy Comtesse of Rheims was born in 950-963 in Rheims, Marne, Loire-Atlantique, France and died before 5 Mar 1003-1005.)
