Tosi Surname in Italy

The surname Tosi, mainly found in Northern Italy, originates from the dialect word 'toso', meaning 'boy', which in turn derives from the Latin 'tonsus', meaning 'shaven'. This connection likely relates to the custom of cutting boys’ hair very short. In some instances, the surname may also come from place names, evidenced by a 1222 record from the Bergamo area referencing a location called Tosilio. Some related forms might stem from nicknames based on the archaic term 'tosello', meaning 'canopy', possibly referring to a proud or boastful ancestor. Early records of the surname appear in Tuscany, with an individual named Ugolinus de Toso de Montemasso dating back to the 1200s. Variants such as Toselli, Tosello, Tosetti, Tosetto, and Toso show distinct regional distributions and origins: Toselli is typical of Piedmont, Lombardy, and Emilia, Tosello of Veneto and Piedmont, Tosetti linked to the Como area, and Tosetto characteristic of Veneto.
