Santini Surname in Italy

The surname Santini is mainly found throughout central and northern Italy, especially in Tuscany, Lazio, and Marche. It originates from the medieval given name Santinus, documented since the 15th century, including an example of Santinus de Folpertis listed among graduates at the University of Pavia in 1441. Variants of the surname reflect distinct regional roots: Santin is typical of Veneto, Santino mostly occurs in Sicily, Santinon is linked to the provinces of Treviso and Padua, and Santinucci is almost exclusively Tuscan. The transition to a family name using the form Santinus is evidenced as early as the late 1500s, with Antonius Santinus, a master stonecutter, recorded in the Como area in 1600.
