Origin
Meaning and origin of Bauzo
The surname Bauzo originated in Spain during the Middle Ages, specifically in the region of Catalonia. It is believed to be derived from the Latin word "baucus," which means "bowl" or "cup." This suggests that the name may have initially been associated with individuals involved in the production or trade of pottery or other ceramic wares.
One of the earliest known records of the Bauzo surname dates back to the 13th century in a medieval manuscript from the city of Barcelona. In this document, a certain Ramon Bauzo was mentioned as a prominent merchant dealing in ceramics and other household goods.
During the 15th century, the Bauzo family gained prominence in the town of Vilanova i la Geltrú, near Barcelona. Records from this period indicate that several members of the family held influential positions within the local government and were involved in various trade and agricultural activities.
In the 16th century, a notable figure named Juan Bauzo (1527-1593) was a renowned artist and sculptor who contributed to the decoration of several churches and cathedrals in Spain. His work can still be seen in various historical buildings across the country.
Another individual of note was Andreu Bauzo (1672-1738), a Catalan writer and philosopher who authored several influential works on ethics and moral philosophy. His writings were widely read and discussed among the intellectual circles of his time.
During the 18th century, the Bauzo family expanded their reach beyond Catalonia, with some members settling in other parts of Spain, as well as in the Spanish colonies in the Americas. One such individual was Pedro Bauzo (1755-1821), who served as a military officer in the Spanish colonial administration in Cuba.
In the 19th century, a notable figure bearing the Bauzo surname was Francisca Bauzo (1823-1901), a renowned educator and advocate for women's rights. She founded several schools and educational institutions in Barcelona, and her work contributed significantly to the advancement of education for women in Spain.
Throughout its history, the Bauzo surname has been associated with various locations and place names, such as Vilanova i la Geltrú, Barcelona, and other towns and villages in Catalonia. The spelling of the name has remained relatively consistent over time, with minor variations appearing in some historical records.

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