Origin
Meaning and origin of Mattiuz
The surname Mattiuz has its origins in northern Italy, specifically in the regions of Friuli-Venezia Giulia and Veneto. It is believed to have emerged sometime during the 13th or 14th century. The name is derived from the Italian given name Mattio, which is a diminutive form of the name Matteo or Matthew.
One of the earliest recorded instances of the name Mattiuz can be found in a document from the year 1332, which mentions a certain "Nicolaus Mattiuz de Portogruaro" from the town of Portogruaro in the province of Venice. This suggests that the name was already in use by that time in that region.
In the 15th century, there are records of a family named Mattiuz residing in the town of Cividale del Friuli, which is located in the province of Udine, Friuli-Venezia Giulia. This family is believed to have played a significant role in the local community and held positions of influence.
A notable figure with the surname Mattiuz was Giacomo Mattiuz, who was born in the town of Gemona del Friuli in 1567. He was a renowned scholar and writer, known for his contributions to the study of Italian literature and linguistics.
Another notable individual with this surname was Giovanni Battista Mattiuz, a 17th-century architect and engineer from the city of Udine. He was responsible for the design and construction of several important buildings and structures in the region.
In the 19th century, a well-known figure was Valentino Mattiuz, who was born in the town of Monfalcone in 1823. He was a prominent businessman and philanthropist, known for his support of various charitable causes and his efforts to improve the lives of the less fortunate in his community.
The name Mattiuz can also be traced back to various place names in northern Italy, such as the village of Mattiussi in the province of Pordenone, Friuli-Venezia Giulia. This village likely took its name from an early settler or family with the surname Mattiuz.
While the surname Mattiuz is not as widespread as some other Italian surnames, it has a rich history and has been associated with notable individuals throughout the centuries, particularly in the regions of Friuli-Venezia Giulia and Veneto.

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 Mattiuz surname at the time of the 2020 Census, not any inherent property of the name itself.
