Origin
Meaning and origin of Doronio
The surname Doronio is of Italian origin, believed to have originated in the region of Tuscany during the late medieval period, approximately between the 13th and 15th centuries. It is thought to be derived from the Latin word "doronium," which refers to a type of plant commonly known as leopard's bane or arnica.
One of the earliest recorded instances of the name Doronio can be found in a Florentine municipal document dated 1347, where it is mentioned as the surname of a local merchant named Pietro Doronio. This suggests that the name had already gained some prominence in the city-state of Florence by the mid-14th century.
In the 16th century, a notable figure bearing the Doronio surname was the Italian playwright and poet, Girolamo Doronio (1507-1577). Born in Siena, he was known for his tragedies and comedies, which were widely performed in the courts of various Italian nobles during the Renaissance.
The name Doronio also has connections to the coastal region of Liguria, where it is speculated to have originated from the town of Doria, a small fishing village near Genoa. This theory is supported by the existence of several historical records mentioning individuals with the surname Doronio residing in the area during the 17th and 18th centuries.
One such individual was Francesco Doronio (1642-1718), a renowned Genoese painter and architect who was commissioned to design several churches and palaces in and around the city of Genoa. His works, particularly the Chiesa di San Siro and the Palazzo Doria Tursi, are considered masterpieces of the Baroque style.
Another notable bearer of the Doronio surname was the Italian philosopher and theologian, Tommaso Doronio (1759-1836), who taught at the University of Bologna and authored several influential works on ethics and moral philosophy.
In the 19th century, the Doronio name gained further recognition with the birth of the Italian artist and sculptor, Vincenzo Doronio (1835-1905). Based in Rome, he was celebrated for his intricate marble sculptures and was commissioned to create several public monuments throughout Italy.
While the surname Doronio is not among the most common Italian surnames today, its historical roots can be traced back several centuries, reflecting the diverse cultural and artistic contributions of those who bore this name throughout the regions of Tuscany, Liguria, and beyond.

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