Origin
Meaning and origin of Baudanza
The surname BAUDANZA is believed to have originated in Italy, specifically in the region of Tuscany, during the medieval period. It is derived from the Italian word "baldanza," which means "boldness" or "bravery." This suggests that the name may have been initially given as a nickname to someone who exhibited these qualities.
One of the earliest recorded instances of the name BAUDANZA can be found in the Florentine Annals, a chronicle of events in Florence, Italy, from the 13th century. The document mentions a nobleman named Guido BAUDANZA, who participated in a famous battle against the rival city of Siena in 1260.
In the 14th century, a branch of the BAUDANZA family settled in the town of Montepulciano, located in the province of Siena, Tuscany. The name appears in several historical records from this region, such as land deeds and tax rolls, indicating their presence in the area.
An influential figure bearing the BAUDANZA surname was Bartolomeo BAUDANZA, a renowned architect and sculptor born in Montepulciano in the late 15th century (c. 1470-1540). He is best known for his contributions to the design and construction of the magnificent Palazzo Vecchio in Florence.
Another notable BAUDANZA was Giovanni BAUDANZA (1509-1572), a humanist scholar and poet from Montepulciano. He was a member of the prestigious Accademia Fiorentina and authored several works in Latin and Italian.
In the 17th century, the BAUDANZA family expanded their presence to other parts of Italy, including the regions of Lazio and Campania. One prominent individual from this era was Ottavio BAUDANZA (1626-1701), a respected jurist and legal scholar who served as a judge in the city of Naples.
While the surname BAUDANZA has its roots in Italy, it has since spread to other parts of the world due to emigration. However, the earliest and most significant historical records of this name can be traced back to its origins in Tuscany and the surrounding areas of central Italy.

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
