Bunyan Family History
Bunyan Name Meaning
English (southeastern): nickname for someone disfigured by a lump or hump from a diminutive of Old French bugne ‘swelling protuberance’. The term bugnon was also applied to a kind of puffed-up fruit tart and so the surname may also have been a metonymic occupational name for a baker of these.
