Origin
Meaning and origin of Iaquinta
The surname Iaquinta is of Italian origin, specifically from the southern regions of the country. It is believed to have emerged in the late medieval period, around the 13th or 14th century. The name is derived from the phrase "Ia quinta," which translates to "the fifth" in Italian. This suggests that the name may have originally been used to distinguish between multiple individuals with the same given name, likely within a family or community.
One of the earliest recorded instances of the Iaquinta surname can be found in the Sicilian town of Trapani, where a document from the late 15th century mentions a certain "Antonino Iaquinta." This document provides evidence of the name's presence on the island of Sicily during the Renaissance era.
In the 16th century, the name appears in various records from the Kingdom of Naples, which encompassed a significant portion of southern Italy at the time. An individual named "Giovanni Battista Iaquinta" is mentioned in a legal document dated 1567, originating from the town of Caserta near Naples.
As the centuries progressed, the Iaquinta surname spread throughout the Italian peninsula and beyond. In the 18th century, a notable figure bearing this name was Vincenzo Iaquinta, a prominent architect from Calabria who was instrumental in the design and construction of several churches and public buildings in the region.
Another notable individual with the Iaquinta surname was Fabio Iaquinta, an Italian professional footballer born in 1979. He played as a striker for various clubs, including Juventus and the Italian national team, and was part of the squad that won the 2006 FIFA World Cup.
Other examples of individuals with the Iaquinta surname include Giuseppe Iaquinta (1855-1928), an Italian-American businessman and banker from Sicily who played a significant role in the development of the Little Italy neighborhood in New York City, and Antonio Iaquinta (1901-1982), an Italian-American mobster who was involved in the Kansas City crime family during the mid-20th century.
While the Iaquinta surname is primarily associated with Italy and Italian-American communities, it has also made its way to other parts of the world through migration and diaspora. However, its origins can be traced back to the southern regions of Italy, where it first emerged as a distinguishing name during the late medieval and Renaissance periods.

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