Origin
Meaning and origin of Montemurno
The surname Montemurno has its origins in Italy, specifically in the region of Calabria, dating back to the medieval period. It is derived from the Italian words "monte" meaning "mountain" and "murno" which is believed to be a derivative of the Latin word "murorum," meaning "walls." This suggests that the name may have been given to people who lived near or worked on fortified walls or structures located on a mountain.
One of the earliest recorded instances of this surname can be found in the Catalogo dei Feudi e Territori, a manuscript dating back to the 15th century, which lists various landholdings and fiefdoms in the Kingdom of Naples. The name Montemurno is mentioned in this document, indicating that it was associated with a particular area or territory during that time.
In the 16th century, a notable figure with the surname Montemurno was Girolamo Montemurno (1516-1592), an Italian humanist and scholar who served as a professor of rhetoric at the University of Padua. He was widely respected for his contributions to the study of classical literature and his writings on rhetoric and poetics.
Another individual of historical significance bearing this surname was Antonio Montemurno (1641-1717), an Italian painter and architect from Naples. He was known for his work on various churches and palaces in the Baroque style, including the Chiesa di San Nicola alla Carità in Naples.
During the 18th century, the Montemurno family was documented as being landowners in the region of Calabria, with their holdings centered around the town of Montemurano, which likely derived its name from the same roots as the surname.
In the 19th century, Giuseppe Montemurno (1825-1901) was a prominent Italian lawyer and politician who served as a member of the Italian Parliament for several terms, representing the region of Calabria.
Another notable figure was Pasquale Montemurno (1878-1957), an Italian composer and conductor who gained recognition for his operas and symphonic works, which were heavily influenced by the musical traditions of his native Calabria.
It is worth noting that variations in the spelling of the surname, such as Montemurano, Montemurno, and Montemurni, have been recorded throughout history, reflecting the regional dialects and linguistic variations within Italy.

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