Medieval English form of Johanne, an Old French form of Iohanna (see JOANNA). This was the usual English feminine form of John in the Middle Ages, but it was surpassed in popularity by Jane in the 17th century.This name (in various spellings) has been common among European royalty, being borne by ruling queens of Naples, Navarre and Castile. Another famous bearer was Joan of Arc, a patron saint of France (where she is known as Jeanne d'Arc). She was a 15th-century peasant girl who, after claiming she heard messages from God, was given leadership of the French army. She defeated the English in the battle of Orléans but was eventually captured and burned at the stake.
