The surname Coco derives primarily from the occupational term cuoco ("cook"), preserved in various medieval and regional forms such as còco, cògo, cògh, cugh, the Sardinian kóku, and the Sicilian dialectal form còcu. It originally identified a person employed as a cook, a profession that held considerable importance in noble households, religious institutions, and public hospices.

According to E. De Felice, the surname belongs to a large family of occupational surnames derived from the culinary trade. The variants Cuoco and Cuocolo are characteristic of Campania and neighboring areas, while Cogo and Cuogo are more common in Emilia-Romagna and northeastern Italy.

Historical Origins

F. Miranda notes that the surname is also linked to the Latin forms Coccus and Cochus. Its transformation into a hereditary surname is documented as early as the 12th century in Lombardy, where a Johannes Cocco appears in a medieval carta venditionis preserved in the Codex Diplomaticus of Milan.

Miranda also suggests that in some cases the surname may have acquired an affectionate meaning similar to the Italian word cocco, meaning "beloved" or "pampered person." However, he considers the occupational origin to be the most probable, especially for southern Italian families.

V. Blunda rejects the affectionate interpretation for Sicily and argues that Sicilian families bearing the surname derive exclusively from the dialectal term còcu, meaning "cook." According to Blunda, the surname reflects the social importance of this profession within the traditional institutions of the island.

Distribution

The surname is found throughout Italy, but it is particularly common in southern Italy and Sicily, especially in the province of Catania. It is also present in Tuscany, Campania, Sardinia, and several regions of northern Italy.
