Origin
Meaning and origin of Melchionno
The surname "MELCHIONNO" is of Italian origin and can be traced back to the medieval period. It is believed to have originated from the Italian region of Campania, particularly in the areas around Naples and the Amalfi Coast.
One of the earliest recorded instances of the name "MELCHIONNO" is found in a 13th-century manuscript from the city of Amalfi, where it was spelled "Melchionne." This spelling variation suggests that the name may have derived from the Italian name "Melchiorre," which itself is a variant of the Hebrew name "Melchior," meaning "king of light."
In the 14th century, the surname "MELCHIONNO" appeared in several official records and documents from the Kingdom of Naples. One notable example is a land registry from 1349, which mentions a certain "Giovanni Melchionno" as a landowner in the town of Sorrento.
The earliest known bearer of the name "MELCHIONNO" was Giacomo Melchionno, a merchant from Naples who lived during the late 15th century. He is mentioned in several trade records from the city, indicating his involvement in maritime commerce along the Mediterranean coast.
Another notable figure with the surname "MELCHIONNO" was Tommaso Melchionno, a 16th-century scholar and philosopher from the town of Ravello. He was known for his work on Aristotelian ethics and his lectures at the University of Naples.
In the 17th century, the name "MELCHIONNO" gained prominence with the birth of Antonio Melchionno (1620-1689), a renowned painter from the city of Naples. His works, which include religious paintings and portraiture, can still be found in various churches and museums throughout Italy.
During the 18th century, the surname "MELCHIONNO" was associated with the noble family of the same name, who owned lands and estates in the region of Campania. One notable member of this family was Giuseppe Melchionno (1738-1812), a prominent lawyer and judge in the city of Naples.
In the 19th century, the name "MELCHIONNO" continued to be found in various records from the Campania region, such as birth and marriage registers. One notable bearer of the name from this period was Vincenzo Melchionno (1825-1901), a renowned architect who designed several churches and public buildings in Naples and the surrounding areas.

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