Origin
Meaning and origin of Tiliano
The surname Tiliano is of Italian origin, with roots tracing back to the medieval period. It is believed to have originated in the regions of Tuscany and Umbria, derived from the Latin word "tilia," meaning linden tree.
One of the earliest recorded instances of the Tiliano name can be found in a 13th-century document from the city of Siena, where a certain Guido Tiliano is mentioned as a landowner. This suggests that the name was already established in that area during the Middle Ages.
In the 14th century, the Tiliano family gained prominence in the town of Foligno, located in the Umbria region. Historical records mention a notable figure named Pietro Tiliano, who served as a magistrate and diplomat for the city-state in the late 1300s.
The name Tiliano is also linked to the town of Tili, located in the province of Siena. It is possible that the surname originated as a toponymic name, referring to individuals who hailed from or resided near this particular location.
Throughout the Renaissance period, several individuals with the Tiliano surname made notable contributions in various fields. One such figure was Girolamo Tiliano (1500-1568), a renowned painter and architect from Siena, known for his work on churches and palaces in the region.
Another notable bearer of the Tiliano name was Luca Tiliano (1570-1637), a scholar and philosopher from Foligno. He authored several works on theology and metaphysics, which were widely studied in Italian universities during his lifetime.
In the 18th century, the Tiliano family established themselves in the city of Naples, where they became involved in the silk trade. One prominent member was Antonio Tiliano (1725-1798), a successful merchant and philanthropist who funded the construction of a hospital and orphanage in the city.
As the centuries progressed, the Tiliano surname spread to other parts of Italy and beyond, with individuals bearing this name making their mark in various fields, including academia, art, and literature.
It is worth noting that alternative spellings of the name, such as Tiliani and Tigliano, have also been documented throughout history, reflecting regional variations and linguistic evolution.

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