 The most famous member of the family, Gian Battista Caccia(called Cacìta by vapriese, because he wasn't really tall) is said to have inspired the main antagonist of Alessandro Manzoni's I Promessi Sposi.In the early nineteenth century, numerous agricultural lands of Vaprio were purchased by two new wealthy families, the Bono and the Acerbi.Thanks also to them, the irrigation system of the surrounding territories was expanded, with the creation of new channels and cables in order to make the best use of the natural waters of the area.
