It derives from the medieval Venetian dialect term avogadro or avogaro which was used to indicate not only the lawyer, but also the public official with administrative responsibilities.
In Brescia already in 1200 the members of some noble families were called Avogadri to whom the bishop had entrusted the defense of his possessions also with the use of arms.
Examples of this surname can be found in Venice in 1400 with a certain Rambaldo Avogaro from Treviso and in 1470 in Bergamo with an Emanuele Avogadro; in 1600 the Avogadros were feudal lords on behalf of the Bishop of Zanano (BS) in Valtrompia.
A very famous character was Count Lorenzo Romano Amedeo Carlo Avogadro of Quaregna and Cerreto (VC) (9/8/1776 - 9/7/1856) remembered for his law which states that: "equal volumes of different gases at equal pressure and temperature contain the same number of molecules".
Typical of Avogadro from Bergamo and Veronese both Avogaro and the very rare Avogari.
