From the Late Latin name Bonifatius, derived from bonum ‘good’ + fatum ‘fate’. In the early Middle Ages the name came to be alternatively written as Bonifacius (with the same pronunciation) and reanalysed as a compound of bonum + facere ‘to do’, i.e. ‘doer of good deeds’. The name was borne by several early saints, including a 7th-century pope and an Anglo-Saxon missionary who evangelized extensively in Germany in the 8th century. The latter was originally named Winfrid, but took the name Bonifacius on entering holy orders.
