Durso Surname in Italy

The surname Durso is extremely rare and shares its geographic distribution with related variants such as D'Urso, which is widespread across Lazio, Campania, Puglia, and Sicily, and Dursi, typically found in Oriolo, Calabria. Other forms include D'Urzo, with clusters in Genoa, Torre del Greco, and Decollatura, and Durzo, which is nearly unique. All these surnames derive directly or through dialectal modifications from the medieval Latin name Ursus, recorded as early as 1012 in Bergamo. Historical records show the presence of the D'Urso family in the 15th century at Ceglie Messapica with Antonio D'Urso, abbot of the Church of Sant'Anna, and in the 17th century in the Cosenza area, where the family acquired the fief of Civita with a baronial title.
