Origin
Meaning and origin of Manniello
The surname Manniello is of Italian origin, originating in the regions of Campania and Basilicata in southern Italy. It is believed to have derived from the Italian word "manno," which means a small horse or pony. The suffix "-iello" is a diminutive, suggesting the name may have originally referred to someone who worked with or bred small horses.
One of the earliest recorded instances of the Manniello surname can be found in the Codice Diplomatico Barese, a collection of medieval documents from the city of Bari, dating back to the 11th century. This suggests that the name has deep roots in the Apulian region of southern Italy.
In the 14th century, a prominent figure named Tommaso Manniello was mentioned in historical records as a member of the Neapolitan nobility. He was a renowned scholar and advisor to the Angevin court in Naples.
During the Renaissance period, a notable artist named Giovanni Battista Manniello (1536-1614) hailed from the town of Nola, near Naples. He was a skilled painter and fresco artist, with some of his works still preserved in local churches.
In the 17th century, a military officer named Domenico Manniello (1621-1688) gained recognition for his service in the Venetian army during the Cretan War against the Ottoman Empire. He was knighted for his bravery in battle.
Another individual of note was Pietro Manniello (1779-1848), a lawyer and politician from the town of Potenza in Basilicata. He played an important role in the Italian unification movement and served as a member of the Neapolitan parliament during the Risorgimento era.
Over the centuries, variations of the Manniello surname have included Manniello, Mannielli, and Mannielli di Manno, with the latter being a more aristocratic form of the name. The surname has also been linked to various place names in southern Italy, such as Manno and Mannopoli, further reflecting its geographical origins.

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