Biography
Odo was the son of Stephen II of Troyes and Meaux, and Adele.[2] He was still a minor at the death of his father, and his uncle Theobald III of Blois acted as regent of Troyes.[citation needed]

In 1060, Odo married Adelaide of Normandy, daughter of Robert I, Duke of Normandy and widow of Enguerrand II, Count of Ponthieu, Lord of Aumale and Lambert II, Count of Lens.[1] After the death of Enguerrand's only daughter Adelaide, her mother Adelaide of Normandy became her heir and hence through his marriage Odo acquired the title Count (or Earl) of Aumale in Normandy by right of his wife.[3]

Adelaide (sometime called Adeliza) was also sister of William the Conqueror,[1] and Odo accompanied his brother-in-law in the Norman conquest of England (1066).[3] Theobald III of Blois then seized Odo's counties in the Champagne region,[citation needed] One version states William I, for his services in the conquest gave Odo Holderness in Yorkshire.[3] Another proposes that the Lordship of Holderness was granted to William's sister Adelaide, in 1087, and Odo became Earl of Holderness by right of his wife.

Odo was, with Alan Rufus and Roger of Poitou, one of the commanders of the army sent by King William II to besiege William de St-Calais at Durham Castle after the Rebellion of 1088, and who signed St-Calais's guarantee of personal safety.

Odo was implicated in a plot to place his son Stephen of Aumale on the English throne.[4] Stephen was the first cousin of brothers William Rufus, King of England and Robert Curthose, Duke of Normandy.[5] Stephen was apparently not put on trial himself as he may have been out of the king's reach in Normandy.[6] Odo was imprisoned in 1095.[citation needed] Odo lost his English lands for his complicity[7] but they were restored to Stephen two years after the death of William Rufus.

Odo married Adelaide of Normandy, daughter of Duke Robert II "the Devil" 6th Duke of Normandy, Comte de Hiémois and Arlotta of Falaise. (Adelaide of Normandy was born about 1030 and died before 1090.)
