Show ContentsGiaco Surname History

A variety of distinguished and notable names have emerged from the beautiful and historical Italian region of Tuscany, including the notable surname Giaco. During the Middle Ages, as populations grew and travel between regions became more frequent, the people of Tuscany, who were originally known only by a single name, found it necessary to adopt a second name to identify themselves and their families. This process of adopting fixed hereditary surnames in Italy began in the 10th and 11th centuries, but it was not completed until the modern era. The development of Italian hereditary surnames followed general principles and were characterized by derivatives from one's given name. The patronymic surname, which is derived from the father's given name, was one of the most common name types found in the region of Tuscany. This system of name-making was widely used because it linked well with the existing Feudal System and during the Christian era, many people named their children after saints and biblical figures. The surname Giaco came from the Italian form of the biblical patriarch, Jacob or in some cases, the name was an Italian given name corresponding to English name James.
