Origin
Meaning and origin of Tullio
The surname Tullio originates from Italy and dates back to the Middle Ages. It is derived from the Latin name Tullius, which was a Roman family name associated with the celebrated Roman orator and statesman Marcus Tullius Cicero. The name is believed to have its roots in the Etruscan language, but its exact meaning is uncertain.
The earliest recorded instances of the surname Tullio can be found in medieval Italian documents, particularly in regions like Tuscany, Lazio, and Umbria. One notable historical reference is the mention of a Tullio family in the Florentine chronicles of the 13th century.
In the 14th century, a prominent figure named Francesco Tullio was a renowned poet and scholar from the city of Perugia. His works shed light on the cultural and literary landscape of the time.
During the Renaissance period, the Tullio surname gained further prominence. Giovanni Tullio Crispolti (1528-1608) was a distinguished Italian painter and architect who worked on various projects in Rome and the surrounding areas.
Another notable individual was Baldassarre Tullio (1589-1667), a Jesuit mathematician and astronomer from Milan. He made significant contributions to the study of celestial mechanics and authored several influential works.
In the 18th century, Gian Battista Tullio (1700-1790) was a celebrated Italian architect and urban planner. He designed numerous churches, palaces, and public buildings in cities like Palermo and Naples.
Over the centuries, the Tullio surname has been associated with various localities and place names in Italy, such as Tullio Valvassina in Lombardy and Tullio Isontino in the Friuli-Venezia Giulia region.
In more recent times, notable individuals with the surname Tullio include the Italian film director and screenwriter Ermanno Olmi (1931-2018), who won several prestigious awards, including the Palme d'Or at the Cannes Film Festival.

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