Origin
Meaning and origin of Delucia
The surname DELUCIA originated in Italy, specifically in the regions of Campania, Lazio, and Sicily. It is derived from the Latin phrase "de Lucia," which translates to "of Lucia." Lucia was a popular name for women during the early Christian era, and it likely referred to a place named after St. Lucy, the patron saint of Syracuse.
In the Middle Ages, the name DELUCIA appeared in various Italian records and manuscripts, including the Codex Diplomaticus Cavensis, a collection of documents related to the Benedictine monastery in Cava dei Tirreni, Campania. One of the earliest recorded individuals with this surname was Nicola DELUCIA, who was mentioned in the Codex in 1227.
During the Renaissance period, the DELUCIA surname was particularly prominent in Naples and its surrounding areas. Several notable individuals bore this name, including Pietro DELUCIA (1510-1578), a renowned sculptor who worked on the cathedral of Naples, and Girolamo DELUCIA (1557-1623), a celebrated painter known for his religious artworks.
In the 17th century, the DELUCIA surname spread to other parts of Italy, including Sicily. One of the most prominent figures with this name was Vincenzo DELUCIA (1629-1695), a Sicilian jurist and statesman who served as the viceroy of Naples from 1688 to 1695.
As the DELUCIA family expanded throughout Italy, some variations in spelling emerged, such as De Lucia, Della Lucia, and Di Lucia. These variations often reflected regional dialects or scribal preferences in documentation.
Another notable individual with the DELUCIA surname was Domenico DELUCIA (1767-1835), an Italian composer and conductor who contributed significantly to the development of Neapolitan opera. His works were widely performed in Italy during the early 19th century.
During the late 19th and early 20th centuries, many Italians with the DELUCIA surname immigrated to other parts of the world, particularly North America and South America, in search of better economic opportunities. This diaspora helped to spread the name beyond its original Italian roots.

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

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 Delucia (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.
