Origin
Meaning and origin of Mazzoccoli
The surname Mazzoccoli is of Italian origin, tracing its roots back to the regions of central and southern Italy during the medieval period. It is believed to have derived from the Italian word "mazzocco," which refers to a type of woolen cap or headdress worn by peasants and commoners.
One of the earliest recorded instances of the name Mazzoccoli can be found in the historic city of Perugia, located in the region of Umbria. In the 13th century, a family bearing this surname is mentioned in local records, suggesting their presence in the area during that time. The name may have initially been associated with individuals involved in the production or trade of these distinctive caps.
As the surname spread across Italy, variations in spelling and pronunciation emerged, such as Mazzocco, Mazzocchi, and Mazzocchetti. These variants often reflected regional dialects and naming conventions. Some early records from the 14th and 15th centuries mention individuals with the surname Mazzoccoli in cities like Naples and Rome.
One notable figure bearing the Mazzoccoli name was Giulio Mazzoccoli, a Renaissance artist and architect who lived from 1525 to 1592. He was born in Viterbo, a town in the Lazio region, and is renowned for his contributions to the design and construction of churches and other buildings in Rome during the late 16th century.
Another prominent individual was Domenico Mazzoccoli, a 17th-century Italian painter from Naples. His works, primarily religious paintings and frescoes, adorned churches and palaces throughout the city and its surroundings. Domenico was active between 1620 and 1665, leaving a lasting impact on the artistic landscape of Naples.
In the 18th century, a branch of the Mazzoccoli family settled in the town of Montella, located in the Campania region of southern Italy. Records from this period mention a Giuseppe Mazzoccoli, a local landowner and prominent figure in the community.
As the centuries passed, the Mazzoccoli surname continued to spread across Italy and beyond, with some bearers emigrating to other parts of Europe and eventually to the Americas. One notable example is Cesare Mazzoccoli, an Italian-American sculptor born in 1897 in Carrara, Italy, who later immigrated to the United States and became known for his works in bronze and marble.
Throughout its history, the surname Mazzoccoli has been associated with individuals from various walks of life, including artists, artisans, landowners, and merchants, reflecting the diverse backgrounds and occupations of those who carried this name over the centuries.

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.
