Giannotti
Giannotti is a surname of Italian origin. It is believed to be a patronymic surname, meaning it is derived from the given name "Giannotto," a variant of "Giovanni." Giovanni is the Italian form of the biblical name John, meaning "God is gracious." As a surname, Giannotti would have indicated "son of Giannotto" or "descendant of Giannotto." The surname is most commonly found in Italy, particularly in the regions of Tuscany, Lazio, and Campania.
The historical usage of surnames in Italy became more widespread during the late Middle Ages and Renaissance.
