Origin
The surname Cortellessa finds its origins in Italy, specifically in the region of Campania, which includes the city of Naples. It is believed to have emerged sometime around the 12th or 13th century.
Cortellessa is derived from the Italian word "cortella," meaning a small knife or dagger. This suggests that the name may have originated as a descriptive nickname for someone who worked with knives or daggers, such as a cutler or a soldier.
One of the earliest recorded instances of the name can be found in a document from the mid-13th century, which mentions a certain Matteo Cortellessa, a blacksmith residing in the town of Salerno. This document provides evidence of the name's existence during that time period.
The name Cortellessa has been associated with several notable individuals throughout history. One such figure was Gian Battista Cortellessa, a 16th-century Italian painter who was active in Naples and known for his religious works. Another was Tommaso Cortellessa, a 17th-century scholar and author from the city of Benevento, who wrote extensively on philosophy and theology.
In the 18th century, a family by the name of Cortellessa held significant influence in the town of Avellino, with several members serving as local officials and landowners. One of the most prominent among them was Giuseppe Cortellessa (1725-1798), who was a respected lawyer and magistrate.
Another noteworthy individual with the surname Cortellessa was Vincenzo Cortellessa (1824-1899), a 19th-century poet and writer from Naples. He was renowned for his contributions to the Neapolitan literary tradition and his works celebrating the city's culture and dialect.
While the name Cortellessa may have originated as a descriptive nickname related to knives or daggers, it eventually became a well-established surname in various parts of Italy, particularly in the regions of Campania and Basilicata.
Demographics
Among Census respondents with the surname Cortellessa, the largest self-reported group is White at 86.1%. The next largest groups are Hispanic (5.6%) and Asian/Pacific Islander (3.7%).
The bar chart below shows how Cortellessa 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 Cortellessa 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.
