A variety of distinguished and notable names have emerged from the beautiful and historical Italian region of Tuscany, including the notable surname Iaco. 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 Iaco came from the Italian form of the biblical patriarch, Jacob.

Iaco Spelling Variations

Italian surnames have a surprising number of forms in comparison with other European surnames because they reflect the regional variations and the many dialects of the Italian language, each of which has its distinctive features. For example, in Northern Italy the most standard Italian surname suffix is "I", whereas in Southern Italy the most typical surname suffix is "O". Sardinian is very different from other forms of Italian and in fact, it is considered to be its own distinct language. Additionally, spelling changes frequently occurred because medieval scribes, church officials, and the bearers of names, spelled names as they sounded rather than according to any specific spelling rules. As a consequence of the major changes in the Italian language and in the local spellings of Italian surnames that occurred over the course of history, there are numerous variations for the surname Iaco. These spelling variations include DiGiacomo, Giacalone, Giacardi, Giacaz, Giaccaglia, Giaccaglini, Giaccardi, Giaccheri, Giacchetti, Giacchi, Giacchin, Giacchini, Giacco, Giacconi, Giacheri, Giachi, Giachini, Giaco, Giacobazzi, Giacob, Giacobbi, Giacobelli, Giacobini, Giacobo, Giacomazzo, Giacomello, Giacometti, Giacomini, Giacomo, Giacovani, Giacovazzo, Giacovelli, Giappichini, Iachelli, Iachetta, Iachi, Iachino, Iacini, Iaco, Iacobacci, Iacobbi, Iacobelli, Iacobini, Iacobitti, Iacobone, Iacoboni, Iicolo, Iacomelli, Iacometti, Iacomi, Iacomini, Iacomino, Iacomo, Iacomoni, Iacone, Iacovacci, Iacovelli, Iacovini, Iacovo, Iacovne, Iacovucci, Iacuelli, Iacullo, Iacuvelli, Iacuzzi, Iapichelli, Iappichini, Zacchetti, Zacchi, Zacco and many more.
