Tammaro Surname in Italy

The surname Tammaro is predominantly Campanian, especially common in the Naples and Caserta areas. It originates from the Latin name Tammarus, an ethnonym referring to inhabitants of the Altilia mountains. The name is historically and geographically connected to figures such as Saint Tammaro, bishop of Benevento in the 5th century, and to the Tammaro River in the Benevento province. There is also a town named after the saint in Campania, who is the patron of Grumo Nevano, implying the surname may denote families devoted to Saint Tammaro. Another plausible origin comes from Lucanian and Calabrian dialects, where 'tàmmaru' means 'rustic' or 'villager', indicating a rural or common origin.
