Origin
The surname Pomposelli originated from Italy, specifically in the region of Tuscany. It is believed to have roots dating back to the 14th century. The name is derived from the Italian word "pomposo," which means pompous or boastful. It is likely that the name was initially a nickname given to someone who exhibited a pompous or arrogant demeanor.
One of the earliest recorded instances of the name Pomposelli can be found in a document from the town of Siena, dated 1392. In this document, a merchant named Giovanni Pomposelli is mentioned, indicating that the name was already established in the region by that time.
During the Renaissance period, the Pomposelli family gained prominence in the city of Florence. In the 16th century, a notable member of the family, Lorenzo Pomposelli (1490-1559), was a respected lawyer and diplomat who served under the Medici family.
Another historical figure bearing the Pomposelli name was Giacomo Pomposelli (1625-1691), a Florentine artist known for his paintings and frescoes. His works can still be found adorning the walls of several churches in Florence and its surrounding areas.
In the 18th century, the Pomposelli family expanded their influence beyond Tuscany. Giovanni Battista Pomposelli (1735-1810) was a military officer who served in the Napoleonic Wars and rose to the rank of general in the Italian army.
Moving into the 19th century, Giuseppe Pomposelli (1819-1892) was a prominent Italian politician and lawyer. He served as a member of the Italian Parliament and was a vocal advocate for the unification of Italy under the House of Savoy.
Throughout its history, the Pomposelli surname has also been associated with various place names in Tuscany, such as the town of Pomposelli near Siena, which likely derived its name from the family's presence in the area.
While the surname Pomposelli may not be as widespread today as it once was, its origins and historical significance remain deeply rooted in the rich cultural heritage of Italy, particularly in the regions of Tuscany and Florence.
Demographics
Among Census respondents with the surname Pomposelli, the largest self-reported group is White at 93.1%. The next largest groups are Two or More Races (4.3%) and Hispanic (1.7%).
The bar chart below shows how Pomposelli 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 Pomposelli surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
