Origin
Meaning and origin of Nardiello
The surname Nardiello is of Italian origin, specifically from the Campania region in southern Italy, with roots dating back to the medieval period. It is believed to have derived from the Italian word "nardo," which refers to the nard plant or spikenard, a fragrant herb used in perfumes and ointments.
The earliest recorded instances of the name Nardiello can be traced back to the 13th century in various historical records and documents from the Kingdom of Naples. Some scholars suggest that the name may have originated as a nickname or occupation-based surname, possibly referring to individuals involved in the cultivation, trade, or use of the nard plant.
One of the earliest known bearers of the name Nardiello was Giovanni Nardiello, a merchant from the city of Naples who was documented in the 14th century records of the Angevin dynasty. Another notable figure was Nicola Nardiello, a renowned goldsmith and jeweler who lived in the 16th century and was commissioned to create intricate pieces for the nobility of the Kingdom of Naples.
In the 17th century, a branch of the Nardiello family settled in the town of Salerno, where they became prominent landowners and influential members of the local community. One member, Antonio Nardiello (1632-1701), was a respected lawyer and legal scholar who served as a judge in the courts of the Kingdom of Naples.
During the 18th century, the Nardiello name gained further recognition with the birth of Giambattista Nardiello (1720-1793), a celebrated architect and engineer who designed several notable buildings and infrastructure projects in Naples and the surrounding region.
Another notable figure was Raffaele Nardiello (1842-1912), a historian and scholar who authored several books on the history and culture of the Campania region, including a comprehensive study on the origins and significance of Italian surnames.
Throughout its history, the Nardiello surname has been associated with various professions, from merchants and craftsmen to scholars and professionals, reflecting the diverse backgrounds and contributions of those who bore this name.

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.

Keep in mind that these are self-reported numbers.
