He and his brother Chad (Mar. 2) were from an English family, educated under Saint Aidan (Aug. 31) of Lindisfarne. Both brothers entered monastic life at Lindisfarne and later became bishops. Cedd travelled as an evangelist among the people of Essex, where Saint Finan (Feb. 17) consecrated him to be their first bishop. He founded two monasteries in Essex, one of whose churches still stands; he built yet another monastery at Lastingham in Yorkshire, where he lived until his repose. He spoke both Irish and Anglo-Saxon, and served as a translator for the Irish at the Synod of Whitby in 664. He reposed at Lastingham not long after the Synod.
