Origin
Meaning and origin of Ciocci
The surname Ciocci is of Italian origin, specifically from the central regions of the country, particularly Lazio and Umbria. It is believed to have originated in the late Middle Ages, around the 13th or 14th century.
One of the earliest references to the name can be found in the historical records of the town of Orvieto, located in the province of Terni, Umbria. In a document dated 1342, a certain Petrus Ciocci is mentioned as a landowner in the area.
The name Ciocci is thought to be derived from the Italian word "ciocco," which means "log" or "tree stump." It is possible that the name was initially given to someone who lived near or worked with logs or timber, such as a woodcutter or a carpenter.
In the 15th century, the name appears in the records of the city of Rome, where a family by the name of Ciocci is mentioned as being involved in the wool trade. This suggests that the name had spread to other parts of central Italy by this time.
One of the earliest known individuals with the surname Ciocci was Giulio Ciocci, a painter born in Ascoli Piceno, in the Marche region, around 1530. He was known for his religious works and paintings depicting biblical scenes.
Another notable figure was Girolamo Ciocci, born in Perugia, Umbria, in 1589. He was a renowned mathematician and astronomer who made significant contributions to the study of celestial mechanics and the motion of planets.
In the 17th century, the name can be found in the records of the city of Florence, where a family by the name of Ciocci owned a prestigious silk weaving workshop. One member of this family, Andrea Ciocci (1626-1701), was a renowned silk merchant and philanthropist who donated generously to the city's churches and charitable institutions.
During the 18th century, a branch of the Ciocci family settled in the region of Abruzzo, where they became prominent landowners and winemakers. One of the most famous members of this branch was Domenico Ciocci (1735-1809), who was known for his exceptional winemaking skills and for producing some of the finest wines in the region at the time.
In the 19th century, the name Ciocci can be found in various parts of Italy, indicating that the family had spread throughout the country. One notable individual from this period was Antonio Ciocci (1821-1892), a lawyer and politician from Naples who played a significant role in the unification of Italy and the establishment of the Italian Parliament.

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.
