Franca Family History
Franca Name Meaning
Portuguese, Spanish, and Catalan: of uncertain derivation. The name is frequent in Catalonia, with the variants de Franca and de la Franca, and seems to refer to a place, perhaps to be interpreted as França, i.e. France. In this case we must also include the Portuguese family name França. On the other hand, Franca could be from the female personal name Franca. Italian: variant (feminine form) of Franco.
