Origin
The surname Masciocchi has its origins in Italy, likely emerging in the Middle Ages between the 11th and 15th centuries. The name is believed to have originated from the Italian region of Abruzzo, specifically in the province of L'Aquila. It may have been derived from the Italian word "maschio," meaning "male," suggesting a possible connection to a male ancestor or a distinguishing physical characteristic.
One of the earliest recorded instances of the name Masciocchi can be found in the Codice Diplomatico Aquilano, a collection of medieval documents from the city of L'Aquila. This document, dating back to the 13th century, mentions a certain "Petrus de Masciocchis," indicating the presence of the surname in the region during that time period.
In the 16th century, records show a notable figure named Giovanni Masciocchi, born in L'Aquila around 1520. He was a prominent jurist and legal scholar who served as a judge and authored several influential works on Roman law.
The name Masciocchi has also been associated with place names in the region. For instance, the town of Mascio, located in the province of L'Aquila, may have a connection to the surname's origins, although the exact relationship remains uncertain.
Another notable individual bearing the Masciocchi surname was Antonio Masciocchi, born in L'Aquila in 1677. He was a renowned architect and engineer who contributed to the reconstruction efforts in the city following a devastating earthquake in 1703.
During the 18th century, the name Masciocchi gained further recognition with the birth of Gaetano Masciocchi in 1760. He was a respected physician and naturalist who made significant contributions to the field of botany, particularly in the study of plant species native to the Abruzzo region.
In the 19th century, the Masciocchi family continued to leave their mark on Italian history. Carlo Masciocchi, born in L'Aquila in 1837, was a prominent lawyer and politician who served as a member of the Italian Parliament.
While the surname Masciocchi is primarily associated with the Abruzzo region, it has since spread to other parts of Italy and beyond, thanks to migration and family dispersal over the centuries.
Demographics
Among Census respondents with the surname Masciocchi, the largest self-reported group is White at 91.7%. The next largest groups are Two or More Races (4.1%) and Asian/Pacific Islander (2.5%).
The bar chart below shows how Masciocchi bearers described their own race and ethnicity on the 2020 Census form. 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 Masciocchi surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
