James the Deacon
After Paulinus left Northumbria, James stayed near Lincoln and continued his missionary efforts, dying sometime after 671, according to the medieval chronicler Bede.Traditionally this event is dated to 625, but the historian D. P. Kirby argues that the mission to Northumbria probably happened before 619.These dates did not always agree and were one of the reasons that Oswiu called the Synod of Whitby in 664 to decide which system of Easter calculation his kingdom would use.[4] It has been suggested that James was Bede's informant for the life of Edwin, the works of Paulinus, and perhaps the Synod of Whitby.His feast day is 17 August (Catholic General Roman Calendar)[1] or 11 October (Church of England).
