Origin
Meaning and origin of Mancini
The surname Mancini originated in Italy during the Middle Ages. It is derived from the Italian word "mancino," which means "left-handed." The name was likely given as a nickname to someone who was left-handed, as this was considered unusual and notable at the time.
One of the earliest recorded instances of the name Mancini can be found in a document from the 13th century in the region of Tuscany. The name was also prevalent in other parts of central Italy, such as Umbria and Lazio.
In the 14th century, the name appears in various historical records, including tax rolls and land deeds. One notable individual from this period was Tommaso Mancini, a merchant from the city of Florence who lived from 1320 to 1395.
During the Renaissance, the Mancini family gained prominence in Rome. Giulio Mancini (1558-1630) was a renowned art historian and connoisseur who wrote extensively about the works of Raphael and Michelangelo.
In the 17th century, Maria Mancini (1639-1715) was a member of the powerful Mancini family from Rome. She was a niece of Cardinal Mazarin and was briefly engaged to King Louis XIV of France before the marriage was called off.
Another notable figure was Francesco Mancini (1672-1737), an Italian composer and music theorist who served as the Maestro di Cappella at the Basilica of San Giovanni in Laterano in Rome.
In the 19th century, Pietro Mancini (1804-1888) was an Italian sculptor and painter who worked in a neoclassical style. His works can be found in various churches and museums throughout Italy.
The name Mancini has also been associated with several notable people in more recent history, including the Italian soprano singer Vittoria Mancini (1924-2011) and the American film director and screenwriter Albert Mancini (1924-2004).

The bar chart below shows how Mancini 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 Mancini surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
