Eudo's brother Ralph was named Castellan of Nottingham, Hubert had custody of Norwich Castle, and Adam was one of the commissioners of the Domesday Survey in 1085.
Eudo received lands in Essex, Hertfordshire, Berkshire, Bedfordshire, Northamptonshire, Cambridgeshire, Huntingdonshire, Hampshire, Norfolk and in Suffolk;[12] as well as being a steward in the English royal household by at least 1072.
[7] He was involved in the building of Colchester Castle, the largest Norman keep built and the first stone keep in England,[13][page needed] becoming its custodian until his death, when it reverted to Crown ownership.
[15] Eudo was a steward to William II also, and was one of the early adherents, witnessing charters and serving in the royal household.
[26] In addition Henry I removed William de Mandeville as Constable of the Tower of London and appointed Eudo to the position.
Eudo died at Préaux in Normandy early in 1120, and was buried in the chapter-house of St John's Abbey, Colchester, which he had founded, on 28 February 1120.
