Origin
Meaning and origin of Fiuza
The surname Fiuza originated in Portugal, where it dates back several centuries. It is believed to be derived from the Portuguese word "fiuz," which means "faithful" or "loyal." This suggests that the name may have been initially bestowed upon an individual who exhibited these qualities.
One of the earliest recorded instances of the Fiuza surname can be found in the archives of the Torre do Tombo, Portugal's national archives, which contain documents dating back to the 12th century. In these records, there are references to individuals bearing the name Fiuza, indicating that the surname was already in use during the medieval period.
The name Fiuza is also associated with several notable figures throughout history. One such individual was João Fiuza, a 16th-century Portuguese explorer and navigator who played a significant role in the exploration and mapping of the coasts of Brazil and Africa.
Another notable figure with the Fiuza surname was Luís Fiuza, a 17th-century Portuguese painter known for his religious works and portraits. His paintings can be found in various churches and museums throughout Portugal.
In the 19th century, José Fiuza Fadrique was a prominent Portuguese politician and lawyer who served as a member of parliament and played a crucial role in the drafting of several important legal reforms.
The Fiuza surname is also associated with the historic town of Fiuza, located in the northern region of Portugal. This town likely derived its name from the surname, suggesting that the Fiuza family may have been influential or prominent landowners in the area.
While the Fiuza surname is predominantly found in Portugal, it has also spread to other countries, particularly those with historical ties to Portugal, such as Brazil and the former Portuguese colonies in Africa and Asia. However, the name remains most closely associated with its Portuguese origins and the rich history of the Fiuza family in that country.

The bar chart below shows how Fiuza bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Fiuza surname at the time of the 2020 Census, not any inherent property of the name itself.
