Origin
Meaning and origin of Campochiaro
The surname Campochiaro is of Italian origin, tracing its roots back to the medieval period. It is a locational name derived from the town of Campochiaro, situated in the province of Campobasso, Molise region of southern Italy. The name itself is a compound of the Italian words "campo," meaning field or countryside, and "chiaro," meaning clear or bright, suggesting that the name's origins were tied to a geographical location known for its pastoral landscapes or perhaps a specific bright, open field.
One of the earliest recorded instances of the Campochiaro surname can be found in the Codice Diplomatico Molisano, a collection of medieval documents from the Molise region, dating back to the 12th century. This suggests that the Campochiaro family had already established itself in the area by that time.
In the 15th century, a notable figure bearing the Campochiaro name was Giacomo Campochiaro, a renowned humanist scholar and poet from the Kingdom of Naples. He was born around 1450 and is known for his Latin poetry and his contributions to the Italian Renaissance.
During the 16th century, the Campochiaro family played a significant role in the history of the Molise region. Antonio Campochiaro, born in 1520, was a prominent military leader and governor of the town of Campobasso. His cousin, Girolamo Campochiaro, born in 1535, was a respected jurist and served as a judge in the Kingdom of Naples.
In the 17th century, the name Campochiaro appeared in the historical records of the Papal States. Vincenzo Campochiaro, born in 1610, was a notable clergyman who served as the Bishop of Ascoli Piceno from 1670 until his death in 1687.
Another noteworthy figure was Pietro Campochiaro, born in 1775, who was a prominent lawyer and politician in the Kingdom of the Two Sicilies during the late 18th and early 19th centuries. He played an active role in the political reforms of that era.
Throughout history, the Campochiaro surname has been associated with various place names and older spellings, such as Campochiaro di Molise, Campochiaro di Campobasso, and Campoclaro, reflecting the evolving nature of language and regional variations.
While the Campochiaro name has deep historical roots in Italy, particularly in the Molise region, it has also spread to other parts of the world through migration and family connections over the centuries.
Demographics

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