Tomaselli Surname in Italy

The surname Tomaselli has very ancient origins and stems from the medieval personal name Thomasus, from which several diminutive forms derive. The name itself is of Hebrew origin, meaning "twins," and is associated with the apostle Thomas. Tomaselli is found throughout Italy, particularly in Sicily, Lombardy, and Trentino-Alto Adige. Related variants such as Tomasello are mostly Sicilian, while Tommaselli is characteristic of the Naples and Benevento areas. Other forms like Tommasetti are very rare, mainly found in central Italy including Marche, Abruzzo, Molise, Lazio, and Naples. Tommasetto is nearly unique and extremely uncommon. All these surnames share a common origin linked to diminutives and adaptations of Thomasus.
