Manca Surname in Italy

The surname Manca is predominantly Sardinian in origin, exhibiting its highest concentration on the island, yet historical evidence also reveals an early presence in Salento. The name derives from dialect nicknames referring to a physical trait, specifically left-handedness, expressed in Sardinian as "sa manu 'e manca" or 'the left hand.' It originates from the Latin term manca, with related forms such as Mancòni, manchìnu, and mancòsu, all signifying the same characteristic. Historical Sardinian records from the 14th century feature numerous individuals bearing Manca and its variant Mancha among the signatories of the 1388 Peace of Eleonora and in various medieval condaghes, where they served in civic and religious roles across inland Sardinian communities. Although the surname appears across Italy, its strongest presence remains in Sardinia, encompassing approximately 267 municipalities, with a smaller but longstanding footprint in Puglia.
