Felix, who originated from the Frankish kingdom of Burgundy, may have been a priest at one of the monasteries in Francia founded by the Irish missionary Columbanus: the existence of a Bishop of Châlons with the same name may not be a coincidence. Felix travelled from his homeland of Burgundy to Canterbury before being sent by Honorius to Sigeberht of East Anglia's kingdom in about 630, (by sea to Babingley in Norfolk, according to local legend). On arrival in East Anglia, Sigeberht gave him a see at Dommoc (possibly Walton, Suffolk or Dunwich in Suffolk). According to Bede, Felix helped Sigeberht to establish a school in his kingdom "where boys could be taught letters". He died on 8 March 647 or 648, having been bishop for seventeen years. His relics were translated from Dommoc to Soham Abbey and then to the abbey at Ramsey.
