Origin
Meaning and origin of Pisoni
The surname Pisoni originated in Italy during the Middle Ages. It is believed to have derived from the Italian word "pisano," which means "from Pisa." This suggests that the earliest bearers of this name likely hailed from the city of Pisa, located in the Tuscany region of central Italy.
Pisa was an important maritime republic during the medieval period, and its residents played a significant role in trade and exploration. The Pisoni surname may have been adopted by individuals or families associated with the city's maritime activities or commerce.
One of the earliest recorded instances of the Pisoni surname dates back to the 13th century, when it appeared in a document from the city of Pisa itself. This document, which is now preserved in the Pisan archives, mentions a certain "Giovanni Pisoni," indicating that the name was already in use at that time.
In the 14th century, the Pisoni name surfaced in other parts of Italy, suggesting that individuals bearing this surname had begun to migrate and settle in different regions. For example, records from the city of Florence mention a "Tommaso Pisoni" who lived during this period.
During the Renaissance, a notable figure bearing the Pisoni surname was Battista Pisoni, a renowned architect who lived from 1490 to 1563. He was responsible for the design and construction of several churches and palaces in the city of Verona, where he spent most of his professional life.
In the 17th century, the Pisoni surname appeared in the records of the Venetian Republic, where a family by the name of Pisoni was involved in the glass-making industry. This industry was a major economic force in Venice during that time, and the Pisoni family may have played a role in its production or trade.
Another significant figure with the Pisoni surname was Francesco Pisoni, a Italian painter who lived from 1620 to 1698. He was known for his religious artwork and frescoes, many of which can still be found in churches throughout Italy.
As the centuries passed, the Pisoni surname continued to spread across Italy and beyond. By the 19th century, individuals bearing this name could be found in various parts of Europe and even in the Americas, where Italian immigrants had settled.
While the Pisoni surname may have originated in the city of Pisa, it eventually became a widespread name across Italy and beyond, carried by individuals from diverse backgrounds and professions, all linked by their shared ancestry and connection to this historic Italian city.

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