The history of the last name Tiu

The surname TIU has its origins in northern Italy, specifically in the region of Piedmont. It is believed to have emerged in the late 13th century, derived from the Old Italian word "tiu," meaning "uncle." This term likely originated as a nickname or a way to distinguish individuals within a family or community.

One of the earliest recorded instances of the name TIU can be found in the archives of the town of Asti, dating back to 1297. A document mentions a certain "Giovanni Tiu," a landowner in the area. This suggests that the name was already established and in use by that time.

In the 14th century, the TIU surname appeared in various municipal records across Piedmont, particularly in the cities of Turin and Cuneo. These records often referred to individuals involved in trades or crafts, indicating that the name was not exclusive to any particular social class.

The name TIU can also be traced back to several small villages in the Piedmont region, such as Tiu, located in the province of Vercelli. It is possible that the surname originated from these place names, as it was common for people to adopt surnames based on their place of origin or residence.

One notable figure bearing the surname TIU was Giacomo Tiu (1520-1592), a renowned architect and engineer from Turin. He was responsible for the design and construction of several notable buildings in the city, including the Church of San Lorenzo and the Palazzo Reale.

Another prominent individual with the surname TIU was Giambattista Tiu (1675-1748), a celebrated painter from Asti. His works, primarily religious paintings and frescoes, can still be found in various churches and museums throughout Piedmont.

In the 18th century, the TIU family established itself as a respected lineage in the city of Cuneo. Giulio Tiu (1712-1788) served as the mayor of Cuneo from 1760 to 1768, and his son, Carlo Tiu (1745-1812), followed in his footsteps, holding the same position from 1792 to 1798.

During the 19th century, the TIU surname spread beyond the borders of Piedmont, with family members establishing themselves in other parts of Italy and even migrating to other countries. One notable figure from this period was Antonio Tiu (1810-1879), a successful businessman and philanthropist from Turin, who founded several charitable institutions in the city.

Throughout its history, the surname TIU has maintained its roots in northern Italy, particularly in the Piedmont region. While the name's popularity may have fluctuated over time, it remains a testament to the rich cultural heritage and diverse influences that have shaped the region's identity.
