Cambi is typically Tuscan, with strains, probably secondary in Emilia and Lazio, Cambio, very rare, seems to be specific to the inhabitants of Caserta and Salerno, deriving from the Latin name Cambius of Celtic origins, of which we have an example in a deed drawn up in Bologna in 1329 : "... Cambius olim Martini Guaraldi, Iohannes quondam Lambertutij, Albertus Bonore ...", traces of this surname can be found in Florence in 1200, in a text of 1263 a certain Ricco Cambi is cited as a representative of the major bankers of the city , in Bergamo in 1500 we read: "... Actorum spectabilis domini vicarii pretorii Bergomi Francescus Cambius et Antonius Rizattus julii et augusti years 1559 ...". additions provided by Giovanni Vezzelli Cambi moves from the medieval proper name Cambio, from the Tuscan area (12th century). It is an apheretic form from (Bon) change "good exchange", a wishful name "given to a child after the death of a previous child" (De Felice). Its dissemination is fair in Modena. Source: F.
