Origin
Meaning and origin of Boldi
The surname BOLDI has its origins in Italy, tracing its roots back to the medieval period. It is believed to have originated in the northern regions of the country, particularly in the areas surrounding the city of Bologna.
One of the earliest recorded instances of the name BOLDI can be found in a document from the 13th century, which mentions a certain Guido Boldi, a nobleman and landowner in the province of Modena. This suggests that the name was already well-established among the aristocratic classes of the region by that time.
The name BOLDI is thought to be derived from the Italian word "boldo," which means "bold" or "daring." This could be a reference to the bold and courageous nature of the original bearer of the name or perhaps a descriptor of their physical stature or appearance.
In the 14th century, several records mention the BOLDI family as prominent merchants and bankers in the city of Florence. One notable figure from this period was Giovanni Boldi, a successful trader and financier who amassed a considerable fortune through his business dealings.
The BOLDI surname also has a strong connection to the city of Venice, where it can be traced back to the 15th century. One of the most famous individuals with this name was Marco Boldi, a renowned navigator and explorer who embarked on several voyages to the East Indies and the Spice Islands in the early 16th century.
Other notable figures throughout history who bore the surname BOLDI include:
1. Antonio Boldi (1608-1672), an Italian architect and sculptor who worked extensively on the construction of churches and palaces in Rome and Naples.
2. Girolamo Boldi (1735-1812), a celebrated Italian composer and music theorist who was particularly renowned for his works in the field of sacred music.
3. Maria Boldi (1848-1923), an Italian painter and illustrator who was part of the Macchiaioli movement, known for her vibrant landscapes and depictions of rural life.
4. Carlo Boldi (1876-1942), an Italian politician and lawyer who served as a member of the Italian Parliament and played a significant role in the drafting of several legal reforms.
5. Adriana Boldi (1895-1980), an Italian actress and singer who enjoyed a successful career on the stage and in early Italian cinema during the first half of the 20th century.
While the surname BOLDI has its roots in Italy, it has since spread to other parts of the world, with descendants of the original families now residing in various countries.
Demographics
Ancestry and ethnicity for Boldi

The bar chart below shows how Boldi 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 Boldi surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.

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