Origin
Meaning and origin of Bazzo
The surname "Bazzo" is believed to have originated in Italy, specifically in the northern regions of Lombardy and Veneto. It is thought to have derived from the Italian word "bazza," which means "spot" or "blotch." This suggests that the name may have originally been given as a nickname to someone with a distinctive birthmark or other physical feature.
One of the earliest recorded instances of the name "Bazzo" can be found in the Estimo della provincia di Venezia, a tax record from the 14th century Venetian Republic. This document lists several individuals with the surname "Bazzo" residing in the city of Venice and surrounding areas.
The name "Bazzo" also appears in various historical documents from the 15th and 16th centuries, such as the Libro delle Famiglie Nobili di Venezia (Book of Noble Families of Venice), indicating that some families bearing this surname held a certain level of nobility or prominence during that time.
One notable individual with the surname "Bazzo" was Girolamo Bazzo (c. 1550-1609), a Venetian architect and engineer who was involved in the construction of several important buildings in Venice, including the Palazzo Contarini dal Zaffo and the Church of San Giorgio Maggiore.
Another person of note was Giovanni Battista Bazzo (1680-1753), an Italian painter and engraver from Genoa who was known for his religious and mythological works.
In the 18th century, the name "Bazzo" can be found in records from the Duchy of Milan, suggesting that the surname had spread to other parts of northern Italy by that time. One individual from this period was Giuseppe Bazzo (1727-1801), a composer and violinist from Milan who served as the director of the Conservatorio di Santa Maria di Loreto.
The name "Bazzo" also appears to have been present in the nearby regions of Emilia-Romagna and Tuscany, as evidenced by various historical records and documents from those areas.
It is worth noting that variations or spellings of the name, such as "Bazzio," "Bazzini," and "Bazzoni," can also be found throughout Italian history, likely due to regional variations or adaptations over time.

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