Origin
Meaning and origin of Trimboli
The surname Trimboli has its origins in Italy, specifically in the southern region of Calabria. It is believed to have emerged during the medieval period, around the 11th or 12th century. The name is thought to derive from the Latin word "trimbulus," which means "three-legged stool" or "tripod." This could suggest that the surname may have been initially given to someone who worked with tripods or stools, perhaps a craftsman or tradesman.
One of the earliest recorded instances of the surname Trimboli can be found in a census record from the town of Reggio Calabria in 1492. The document mentions a family with the surname Trimboli residing in the area. Additionally, there are mentions of the name in various historical records from nearby towns and villages in Calabria, such as Catanzaro and Crotone, during the 15th and 16th centuries.
In the 17th century, the Trimboli surname appeared in several historical documents from the city of Naples. One notable individual from this period was Giovanni Trimboli, a renowned painter born in Naples in 1628. His works can still be found in various churches and galleries throughout Italy.
During the 18th century, the Trimboli name spread beyond the confines of Calabria and Naples. Records show that a family with this surname had settled in the city of Palermo, Sicily. One of the most notable figures from this time was Antonio Trimboli, a lawyer and politician who served as a magistrate in Palermo in the late 1700s.
As the Trimboli surname continued to spread across Italy, it also began to appear in other parts of Europe. In the 19th century, there are records of individuals with this surname residing in countries like Spain and France. One such individual was Maria Trimboli, a Spanish artist born in Barcelona in 1819, who gained recognition for her intricate still-life paintings.
Another noteworthy figure with the Trimboli surname was Giuseppe Trimboli, an Italian writer and journalist born in Catanzaro in 1875. He was known for his work as a correspondent during World War I and his contributions to various Italian newspapers and magazines.
While the surname Trimboli has its roots in southern Italy, particularly in the region of Calabria, it has since spread across the country and beyond, with individuals bearing this name making their mark in various fields throughout history.

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