Origin
Meaning and origin of Nardacci
The surname Nardacci is of Italian origin, specifically from the region of Umbria in central Italy. It likely dates back to the medieval period, around the 12th or 13th century. The name is derived from the Italian word "nardo," which refers to the spikenard plant, a type of aromatic herb native to the Mediterranean region. It is believed that the name may have originally been a nickname or a descriptive name for someone who cultivated or worked with spikenard.
One of the earliest known references to the name Nardacci can be found in the chronicles of the town of Foligno, located in the province of Perugia, Umbria. These chronicles, dating back to the 13th century, mention a family with the surname Nardacci who were prominent landowners and merchants in the area.
In the 15th century, a friar named Tommaso Nardacci gained recognition for his contributions to the Franciscan order and his scholarly works on theology and philosophy. He was born in Foligno in 1410 and died in 1485.
Another notable figure with the surname Nardacci was Girolamo Nardacci, a 16th-century architect and sculptor from Foligno. He is credited with designing several churches and public buildings in the city, including the Church of Santa Maria delle Grazie, which was completed in 1560.
During the 17th century, the Nardacci family continued to be influential in the Umbria region. Pietro Nardacci (1619-1693) was a respected lawyer and judge who served in the local courts of Foligno.
In the 19th century, a member of the Nardacci family named Giuseppe Nardacci (1825-1892) gained prominence as a poet and writer. He published several collections of poems and literary works that celebrated the culture and traditions of Umbria.
While the name Nardacci is most commonly associated with the Umbria region of Italy, it is worth noting that variations of the name, such as Nardacci, Nardaccio, and Nardacci, can be found in other parts of Italy as well, although their origins and histories may differ slightly.

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