Origin
Meaning and origin of Antonelli
The surname Antonelli originated in Italy, most likely in the regions of Tuscany and Umbria, during the Middle Ages. It is derived from the Latin personal name "Antonius" or "Antonellus," which was a diminutive form of the name.
One of the earliest recorded instances of the surname can be found in the Florentine tax records of 1427, where a certain Piero di Nello Antonelli is mentioned. This suggests that the name had already been established in the region by the 15th century.
The name Antonelli is also found in various historical documents from the Renaissance period. For instance, Pietro Antonelli (1465-1530) was a renowned Italian architect and military engineer who worked on fortifications in Rome and other Italian cities.
Another notable bearer of the name was Giovanni Battista Antonelli (1528-1588), an Italian cardinal and diplomat who served as the papal legate to several European courts during the Counter-Reformation.
In the 17th century, Giacomo Antonelli (1646-1718) was a respected painter from the city of Velletri, near Rome, known for his works in the Baroque style.
During the 19th century, Giacomo Antonelli (1806-1876) was a powerful Italian cardinal and statesman who served as the Secretary of State for the Papal States under Pope Pius IX.
Another prominent figure with the surname Antonelli was the Italian physicist and electrical engineer Giovanni Antonelli (1838-1918), who made significant contributions to the development of electrical engineering and the study of electromagnetism.
It is worth noting that the name Antonelli has also been associated with various places in Italy, such as the town of Antonelli in the province of Messina, Sicily, and the village of Antonelli in the province of Teramo, Abruzzo.

The bar chart below shows how Antonelli 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 Antonelli 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 Antonelli (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.
