Origin
The surname DICIURCIO originated from Italy, with its earliest recorded instances dating back to the 14th century. The name is believed to have derived from the Italian phrase "di Ciurcio," which translates to "of Ciurcio" or "belonging to Ciurcio." This suggests that the surname may have initially been a descriptive name, perhaps referring to an individual's place of origin or association with a particular location.
One of the earliest documented references to the surname DICIURCIO can be found in the census records of the town of Salerno, located in the Campania region of southern Italy. In these records, dated around the year 1380, there are several entries for individuals bearing variations of the name, such as "Diciurchio" and "Diciurcio."
As the name spread and evolved over time, various spelling variations emerged, including "Diciurcio," "Diciurchio," "Diciurci," and "Dicicco." These variations were likely influenced by regional dialects, scribal errors, and phonetic adaptations.
Notable bearers of the DICIURCIO surname throughout history include Antonio DICIURCIO (c. 1450-1520), a renowned painter from Naples who was commissioned to create frescoes for several churches in the region. Another notable figure was Giacomo DICIURCIO (1620-1690), a prominent architect who designed several notable buildings in the city of Salerno during the 17th century.
In the 19th century, Giuseppe DICIURCIO (1845-1917) was a respected lawyer and political activist who played a significant role in the Italian unification movement. He was known for his passionate speeches advocating for democratic reforms and social justice.
During the early 20th century, Maria DICIURCIO (1890-1968) gained recognition as a pioneering educator and advocate for women's rights. She established several schools in her hometown of Salerno and worked tirelessly to promote educational opportunities for girls and women.
Another prominent figure was Vincenzo DICIURCIO (1920-2005), a celebrated writer and poet whose works explored themes of love, loss, and the human condition. His poetry collections, such as "Versi d'Amore" (Verses of Love), received critical acclaim and garnered him numerous literary awards.
Throughout its history, the surname DICIURCIO has maintained a strong presence in various regions of Italy, particularly in the southern regions of Campania and Basilicata. While its origins can be traced back to the 14th century, the name continues to be carried by individuals of Italian descent, serving as a testament to their rich cultural heritage and family lineage.
Demographics
Among Census respondents with the surname Diciurcio, the largest self-reported group is White at 92.1%. The next largest groups are Hispanic (5.0%) and Asian/Pacific Islander (3.0%).
The bar chart below shows how Diciurcio 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 Diciurcio surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
