Origin
Meaning and origin of Quagliariello
The surname QUAGLIARIELLO originated in southern Italy, specifically in the region of Campania. It dates back to the early Middle Ages, around the 11th or 12th century. The name is believed to be derived from the Italian word "quaglia," which means "quail," and the suffix "-riello," which indicates a smaller or diminutive form. This suggests that the name may have initially referred to someone who worked with or traded in quails.
The earliest recorded instances of the QUAGLIARIELLO name can be traced back to medieval records and manuscripts from the Kingdom of Naples and the surrounding areas. One notable example is a document from the 13th century that mentions a landowner named Girolamo QUAGLIARIELLO in the town of Avellino.
In the 14th century, there are records of a family called QUAGLIARIELLO residing in the town of Salerno. The name was also present in other parts of Campania, such as Benevento and Caserta, during this period.
The name QUAGLIARIELLO has been associated with several notable individuals throughout history. One of the earliest was a poet named Giovanni QUAGLIARIELLO, who lived in Naples in the late 15th century and wrote works in the Neapolitan dialect.
Another prominent figure was Tommaso QUAGLIARIELLO, a lawyer and politician who served as a member of the Neapolitan Parliament in the early 19th century (born in 1785, died in 1861).
In the late 19th century, a musician named Vincenzo QUAGLIARIELLO (1837-1909) gained recognition for his compositions and performances in the traditional Neapolitan song genre.
During the 20th century, the name QUAGLIARIELLO was carried by several scholars and academics, such as Gaetano QUAGLIARIELLO (1887-1971), a historian and professor at the University of Naples.
More recently, Gaetano QUAGLIARIELLO (born in 1960) is a politician and member of the Italian Senate, representing the region of Campania.
While the name QUAGLIARIELLO is still more commonly found in southern Italy, it has also spread to other parts of the country and even internationally due to migration patterns over the centuries.

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