Cantu is a surname of toponymic origin derived from Cantù, the city located in the province of Como, in Lombardia. According to E. Rossoni, the surname originally identified individuals or families who came from that locality.

Several interpretations have been proposed for the origin of the place name Cantù. According to Olivieri, it derives from the Latin term canthus, meaning a corner, edge, or angle of land. Mirabella Roberti, however, suggests that the name may preserve the memory of an ancient people known as the Cantures.

Distribution

The surname is historically associated with Lombardia, particularly the area of Como and the broader region of Brianza. Its diffusion reflects the importance of Cantù as a local center from which families migrated to neighboring territories.

Notes

Historical records cited by Surnames in Italy document the presence of the surname in the area of Monza before the 13th century. The name is officially recorded in Monza from the 15th century onward.

Families associated with the surname and linked to the Brianza region are documented as early as 1237 in the territory south of Lake Pusiano, providing evidence of the surname's long-standing presence in Lombardy.

Cantu is therefore a classic Italian toponymic surname, preserving the geographic origin of families whose ancestral roots can be traced to the historic city of Cantù.
