Origin
Meaning and origin of Delpopolo
The surname DELPOPOLO is of Italian origin, believed to have originated in the regions of Tuscany and Lazio during the late medieval period. It is derived from the Italian phrase "del popolo," which translates to "of the people" or "of the common folk."
The name DELPOPOLO likely emerged as a way to distinguish individuals or families who were part of the general populace, as opposed to those of noble or aristocratic descent. It may have been used to identify individuals who were commoners, workers, or members of the lower social classes.
Historical records indicate that the name DELPOPOLO appeared in various documents and manuscripts from the 14th and 15th centuries. One notable mention is found in the archives of the Republic of Florence, where a certain Giovanni DELPOPOLO is listed as a merchant in the year 1427.
In the late 15th century, a variant spelling of the name, "Delpopulo," is recorded in the parish records of the town of Viterbo, located in the region of Lazio. This suggests that the name may have been more prevalent in central Italy during that time period.
One of the earliest recorded instances of the name DELPOPOLO dates back to the early 16th century, when a man named Giulio DELPOPOLO was born in the city of Siena in 1501. He was a renowned sculptor and architect, known for his work on the Cathedral of Siena and the Piccolomini Library.
Another notable figure with the surname DELPOPOLO was Pietro DELPOPOLO (1564-1633), a Venetian painter and engraver who was active during the Renaissance period. His works can be found in various churches and galleries throughout Italy.
In the 18th century, a branch of the DELPOPOLO family settled in the region of Campania, where a man named Vincenzo DELPOPOLO (1720-1789) became a prominent landowner and businessman in the city of Naples.
The 19th century saw the birth of Giacomo DELPOPOLO (1838-1912), a Italian-American author and journalist who immigrated to the United States in the late 1800s. He wrote extensively about the experiences of Italian immigrants in America and was a vocal advocate for their rights and integration.
Lastly, in the early 20th century, a woman named Maria DELPOPOLO (1901-1983) gained recognition as a talented opera singer and soprano. Born in Rome, she performed in various theaters across Europe and was particularly acclaimed for her interpretations of works by Verdi and Puccini.

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