Origin
Meaning and origin of Mucciolo
The surname Mucciolo originates from Italy, specifically the region of Campania, and can be traced back to the 15th century. It is believed to have derived from the Italian word "moccio," which means "booger" or "snot." This may suggest that the name was initially a nickname given to someone with a particular physical characteristic or habit.
In the early 16th century, the name Mucciolo appeared in several historical documents from the city of Naples, indicating that it was already well-established in the area. One notable reference is found in the baptismal records of the Church of San Giovanni Maggiore, where a certain Giovanni Mucciolo is mentioned as a godfather in 1522.
The earliest recorded instance of the surname Mucciolo can be found in a census document from the town of Acerra, dated 1487. The document lists a family headed by a man named Nicola Mucciolo, who was a farmer and landowner.
Throughout the centuries, the Mucciolo name has undergone various spelling variations, such as Muccioli, Muciolo, and Mucioli, reflecting regional dialects and scribal errors in record-keeping.
One of the earliest notable individuals bearing the Mucciolo surname was Gian Battista Mucciolo (1555-1628), a renowned painter from Naples who specialized in religious art and frescoes. His works can still be admired in several churches and cathedrals throughout southern Italy.
Another prominent figure was Vincenzo Mucciolo (1675-1742), a Neapolitan lawyer and scholar who wrote extensively on legal matters and served as a judge in the city's court system.
In the 19th century, Giuseppe Mucciolo (1823-1892) gained recognition as a poet and playwright from the town of Avellino. His most celebrated work, "L'ammore 'e Pulicenella" (The Love of Pulcinella), is considered a classic of Neapolitan theater.
The name Mucciolo also has connections to the town of Montella, located in the province of Avellino. In the 18th century, a wealthy landowner named Antonio Mucciolo (1712-1789) was a prominent figure in the local community and owned vast estates in the surrounding area.
Lastly, it is worth mentioning Antonio Mucciolo (1923-2002), a renowned Italian chef and restaurateur who introduced authentic Neapolitan cuisine to the United States. He opened several successful restaurants in New York City, and his cookbook, "La Cucina Napoletana," became a classic reference for lovers of Italian cooking.

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