Bonnet is a French surname derived from the medieval given name Bonnet, itself a diminutive of the Latin bonus (good, kind). It was a common baptismal name in medieval France — particularly in the Rhône valley and the southeast — before becoming a hereditary surname. Today it is one of the characteristic surnames of the Lyonnais and Dauphiné regions.

History and Origins
The name Bonnet developed during the medieval period as a baptismal name meaning 'the good little one' — a term of endearment combining the Latin bonus (good) with the diminutive suffix -et. Saint Bonnet (Bonet, Bonitus), a seventh-century bishop of Clermont in the Auvergne, was venerated across southern France, and his cult helped propagate the name throughout the region. When hereditary surnames crystallised in France, families who bore this given name — or who lived near a chapel dedicated to Saint Bonnet — took Bonnet as their family name.
Lyon and the Silk Trade
The Bonnet surname is particularly associated with Lyon and the surrounding Lyonnais region — France's second city and the historic centre of the European silk trade. Bonnet families appear prominently in Lyon's guild records as silk weavers (canuts), merchants, and artisans from the medieval period through the nineteenth century. The Lyon silk industry was one of the most important in Europe, and Bonnet families were part of its complex social world.
The Canuts and Social History
Lyon's silk weavers (canuts) were among the most politically significant working-class communities in nineteenth-century France, staging the famous Canut Revolts of 1831 and 1834 — the first major industrial labour uprisings in French history. Bonnet families in Lyon were part of this world, and their history is inseparable from the history of French labour and social movements.
The French Diaspora
Bonnet families emigrated to Quebec during the French colonial period, and the name appears in Quebec records from the founding era. The PRDH at the Université de Montréal and the Drouin Collection are primary resources. In France, the surname remains concentrated in the Rhône-Alpes region — particularly around Lyon (Rhône), Grenoble (Isère), and into Savoie and Provence.
The Bonnet name also appears in Switzerland — particularly in the French-speaking cantons of Geneva, Vaud, and Neuchâtel — where it is well established. Swiss Bonnet families emigrated both to France and to the Americas. In Louisiana, the Bonnet name appears from French colonial settlement. The name is also found among Huguenot diaspora communities in England, the Netherlands, and South Africa, reflecting the Protestant heritage of many southern French families.
How to Research Bonnet Ancestry
Bonnet research should focus on the Rhône-Alpes region — Lyon (Archives du Rhône), Grenoble (Archives de l'Isère), and Savoie — for metropolitan French Bonnets. French civil registration (état civil) begins in 1792; earlier Lyon guild records and parish registers are held in the Archives municipales de Lyon. For Quebec, use the PRDH at Université de Montréal. Swiss Bonnet families appear in cantonal archives in Geneva, Vaud, and Neuchâtel. Watch for the variant spellings Bonnet dit [secondary name] in Quebec records.
