Origin
Meaning and origin of Eusanio
The surname EUSANIO is of Italian origin, with roots tracing back to the central region of Italy during the medieval period. It is believed to have derived from the Latin word "eusanus," which means "from Eusano" or "of Eusano," referring to a small town located in the Abruzzo region.
One of the earliest recorded instances of this surname can be found in a document from the 13th century, where a certain Giovanni Eusanio was mentioned as a landowner in the vicinity of the town of Eusano. This suggests that the surname may have originated as a way to identify individuals from this particular locality.
In the 15th century, the name EUSANIO appeared in several historical records, including a manuscript detailing the lineage of a noble family from the Abruzzo region. This document mentions a Tommaso Eusanio, born in 1432, who served as a military commander during the conflicts between various Italian city-states.
During the Renaissance period, the surname EUSANIO gained recognition through the work of a renowned Italian humanist and philosopher, Pietro Eusanio (1477-1542). Born in the town of Eusano, he became a respected scholar and author, contributing to the intellectual discourse of his time.
Another notable figure with this surname was Girolamo Eusanio (1582-1657), a Baroque painter from the Abruzzo region. His works, primarily religious frescoes and altarpieces, can be found in various churches and museums throughout central Italy.
In the 18th century, the EUSANIO surname was associated with a prominent family of merchants and landowners based in the city of Aquila. One of their descendants, Antonio Eusanio (1724-1788), was a successful entrepreneur who established a thriving textile business, contributing to the economic growth of the region.
Throughout the centuries, the EUSANIO surname has maintained a strong presence in the central regions of Italy, particularly in the provinces of Abruzzo and Lazio. While not as widespread as some other Italian surnames, it has been carried by individuals from various walks of life, including scholars, artists, and businessmen.

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