Origin
Meaning and origin of Mucci
The surname Mucci originates from Italy, with its earliest recorded use dating back to the 13th century. It is believed to have derived from the Latin word "mucius," which means "pointed" or "sharp." This name may have initially referred to a person's physical appearance or personality traits.
The Mucci name is predominantly found in the central and southern regions of Italy, particularly in the regions of Lazio, Abruzzo, and Campania. Some of the earliest records of the name can be found in medieval documents and records from cities like Rome and Naples.
One of the earliest known bearers of the Mucci name was Pietro Mucci, a nobleman and landowner who lived in the town of Rieti, near Rome, in the 14th century. Historical records show that he was involved in local politics and held significant influence in the region.
In the 15th century, the Mucci family gained prominence in the city of Naples, where they were involved in trade and commerce. Records from this period mention a wealthy merchant named Giacomo Mucci, who owned several ships and traded goods across the Mediterranean.
Another notable figure with the Mucci surname was Vincenzo Mucci, a renowned artist and sculptor who lived in Rome during the 16th century. Some of his works can still be found in various churches and palaces throughout the Eternal City.
During the Renaissance period, the Mucci family produced several scholars and intellectuals. One such individual was Giulio Mucci, a humanist and philosopher born in Abruzzo in the late 15th century. He wrote extensively on topics ranging from literature to theology and was highly respected in academic circles.
In the 18th century, a branch of the Mucci family settled in the town of Avezzano, in the Abruzzo region. Here, they became known for their involvement in the local agricultural industry, particularly in the cultivation of grapes and the production of wine.
Throughout history, the Mucci name has also been associated with several place names in Italy, such as Mucci di Nazza, a small village in the province of Frosinone, and Contrada Mucci, a rural area in the town of Caserta.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Mucci (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
