Origin
Meaning and origin of Giambrone
The surname Giambrone has its origins in Italy, specifically in the regions of Sicily and Calabria. It is believed to have emerged during the medieval period, around the 12th or 13th century.
The name Giambrone is derived from the Italian word "giambrone," which means "a large gown or cloak." This suggests that the name may have initially been given as a descriptive nickname to someone who wore a distinctive gown or cloak, perhaps a member of the clergy or a merchant.
Some of the earliest recorded instances of the name Giambrone can be found in historical documents from southern Italy, such as tax records and property deeds. For example, a certain Giovanni Giambrone was mentioned in a land transfer document from the city of Palermo, Sicily, dated around 1350.
In the 15th century, a notable figure bearing the name Giambrone was Antonio Giambrone, a scholar and philosopher from Reggio Calabria, who lived from approximately 1420 to 1490. He was known for his works on logic and metaphysics, which were influential during the Renaissance period.
Another prominent individual with the surname Giambrone was Francesco Giambrone, a 16th-century painter from Sicily who was active in the city of Messina. His works, which included religious paintings and portraits, can still be found in various churches and museums in Sicily.
In the 18th century, the name Giambrone was associated with the town of Giambrone, located in the province of Agrigento, Sicily. It is believed that some members of the Giambrone family may have originated from or held lands in this area, contributing to the spread of the surname.
One noteworthy figure from this time period was Giuseppe Giambrone, a playwright and poet who lived in Palermo from 1735 to 1809. His works, which often explored themes of love and social commentary, were widely acclaimed during his lifetime.
Another individual worth mentioning is Vincenzo Giambrone, a 19th-century politician and lawyer from Catania, Sicily, who was born in 1820 and served as a member of the Italian Parliament during the early years of the unified Italian state.

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