Mainly North American: transferred use of the surname, originally a Norman baronial name (d'Airelle) borne by a family who came from Airelle in Calvados. It was first used as a given name towards the end of the 19th century.
English and Welsh: patronymic from the Middle English personal name Jon(e) (see John). The surname is especially common in Wales and southern central England. In North America this name has absorbed various cognate and like-sounding surnames from other languages. (For forms, see Hanks and Hodges 1988).
