The surname Basilio originated in Italy, derived from the Greek name "Basilios," meaning "kingly" or "royal." It was a popular name during the Byzantine era and was often used for Byzantine emperors and high-ranking officials.
One of the earliest recorded instances of the surname Basilio can be found in the 11th century, where it appears in a document from the Republic of Venice. This document mentions a certain "Giovanni Basilio," a merchant from the city of Venice.
During the Middle Ages, the name Basilio was particularly prevalent in the regions of Campania and Calabria in Southern Italy. It was often associated with noble families and landowners, suggesting a connection to Byzantine nobility who had settled in these areas.
In the 14th century, a notable figure named Basilio Falco di Benevento (1285-1349) was a renowned jurist and legal scholar. He served as a judge in the city of Benevento and wrote several treatises on Roman law.
Another prominent individual with the surname Basilio was Girolamo Basilio (1520-1591), a humanist scholar and poet from the city of Naples. He was known for his Latin poetry and his translations of ancient Greek texts.
In the 17th century, a Neapolitan artist named Gian Battista Basilio (1639-1707) gained recognition for his religious paintings and frescoes. His works adorned several churches and palaces in Naples and the surrounding regions.
During the 18th century, the surname Basilio was also found in Sicily, where a family by the name of Basilio di Palermo owned vast estates and vineyards. One of their descendants, Giuseppe Basilio (1758-1832), was a respected winemaker and businessman.
Another notable figure was Carlo Basilio (1845-1912), an Italian politician and lawyer from the Basilicata region. He served as a member of the Italian Parliament and was a vocal advocate for the rights of peasants and agricultural workers.
Throughout its history, the surname Basilio has been associated with various professions, including merchants, scholars, artists, and landowners. Its Greek origins and connections to Byzantine nobility have contributed to its enduring presence in Italy and the Mediterranean region.
Demographics
Among Census respondents with the surname Basilio, the largest self-reported group is Hispanic at 56.0%. The next largest groups are Asian/Pacific Islander (29.3%) and White (10.6%).
The bar chart below shows how Basilio 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 Basilio 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.

For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
