Nigel first became Treasurer in the reign of HenryI,Barlow English Church p. 79 and seems to have held that office from around 1126.Fryde, et al. Handbook of British Chronology p. 103Green Government of England p. 263Hollister "Origins of the English Treasury" English Historical Review p. 271 He was already a receiver, or auditor and administrator, in the treasury of Normandy,Coredon Dictionary p. 235 and he served as treasurer for both realms,Chibnall Anglo-Norman England p. 125 moving with the king and court between England and Normandy.Karn "Nigel" Historical Research p. 302 The date of his appointment is unclear, as until he became a bishop, royal charters listed him as "nephew of the bishop" (Roger of Salisbury) rather than by any office he held. In 1131, though, he was listed in a papal letter as "Nigel, the treasurer", which securely establishes that he held the office at that date.
