Origin
Meaning and origin of Quintiliano
The surname Quintiliano has its origins in Italy, with the earliest records dating back to the 15th century. It is derived from the Latin name Quintilianus, which itself is a derivative of the Roman family name Quintilus.
The name Quintilianus was associated with the Roman rhetorician and writer Marcus Fabius Quintilianus, who lived from around 35 AD to 100 AD. He is considered one of the most influential figures in the history of rhetorical theory and education.
One of the earliest recorded instances of the surname Quintiliano can be found in a 1492 document from the city of Naples, where a certain Giovanni Quintiliano is mentioned as a landowner. This suggests that the name was already established in the region by the late 15th century.
In the 16th century, the surname appears to have spread to other parts of Italy, with records showing individuals bearing the name in cities like Florence and Rome. One notable figure from this period was Pietro Quintiliano, a Renaissance painter who lived in the late 1500s and was known for his religious works.
As the centuries progressed, the Quintiliano surname continued to be associated with various notable figures. In the 18th century, there was Antonio Quintiliano, an Italian architect who designed several churches and palaces in Naples and its surrounding areas.
Moving into the 19th century, Giuseppe Quintiliano was an Italian politician and lawyer who served as a member of the Italian parliament in the latter half of the 1800s. He was born in 1825 and died in 1898.
Another significant figure with the Quintiliano surname was Vincenzo Quintiliano, an Italian composer and conductor who lived from 1871 to 1945. He is best known for his operas and orchestral works, which were highly regarded during his lifetime.
While the surname Quintiliano has its roots in Italy, it has since spread to other parts of the world, particularly in regions with significant Italian diaspora populations. However, its origins can be traced back to the Latin name Quintilianus and its association with the Roman rhetorician Marcus Fabius Quintilianus, as well as the various notable individuals who have borne the name throughout history.

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