Origin
Meaning and origin of Quatraro
The surname Quatraro originated in Italy, specifically in the southern regions of Campania and Calabria, where it can be traced back to the 15th century. The name is derived from the Latin word "quaternarius," meaning "a group of four," which suggests that the name may have originally referred to a family group or a collective of four households or individuals.
One of the earliest recorded instances of the name Quatraro appears in a municipal record from the town of Vibo Valentia, Calabria, dated 1478, where a certain Niccolò Quatraro is mentioned as a landowner. This suggests that the family had already established itself as a prominent presence in the area by the late 15th century.
In the 16th century, the name can be found in various documents from the Kingdom of Naples, including tax records and property deeds. Notable individuals from this period include Giovanni Battista Quatraro (1520-1589), a renowned jurist and legal scholar who served as a magistrate in Naples.
As the Quatraro family expanded and migrated to other parts of Italy, the name underwent minor spelling variations, such as Quatraro, Quatrano, and Quattraro. One notable figure from the 17th century was Francesco Quatraro (1623-1697), a Neapolitan painter known for his religious works and frescoes adorning churches across southern Italy.
In the 19th century, the name gained prominence with the birth of Antonio Quatraro (1836-1913), a prominent politician and statesman from Calabria who served as a member of the Italian Parliament and was instrumental in advocating for the rights of southern Italian regions.
Another notable individual was Raffaele Quatraro (1892-1976), a celebrated architect and urban planner who was responsible for the design and reconstruction of several cities in southern Italy after the devastating earthquakes of the early 20th century.
Throughout its history, the surname Quatraro has been associated with various place names and regions in southern Italy, such as Quatraro di Castrovillari, a small town in the province of Cosenza, Calabria, and Quatraro di Gioia Tauro, a hamlet near the city of Reggio Calabria.

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.
