Bonnet Family History

French: from the medieval personal name Bonettus, a diminutive of Latin bonus ‘good’. French: occasionally, a Gascon variant of Bonneau. English and French: metonymic occupational name for a milliner, or a nickname for a wearer of unusual headgear, from Middle English bonet, Old French bon(n)et ‘bonnet’, ‘hat’. This word is found in medieval Latin as abonnis, but is of unknown origin. In Germany the name was borne by Waldensians, of French origin.
