Origin
The surname "DAURO" is believed to have originated in Italy, specifically in the region of Sicily. It is thought to have derived from the Latin word "daurum," which means "golden" or "gilded." This suggests that the name may have initially referred to someone who worked with gold or had a golden complexion.
The earliest known records of the surname "DAURO" date back to the 13th century in Sicily. It is mentioned in several medieval documents and chronicles from that region. One notable reference is found in a manuscript from the year 1287, which mentions a nobleman named Roberto Dauro who owned land near the city of Palermo.
In the 14th century, the name appears in several tax records and land registries in various parts of Sicily. One of the earliest recorded instances is a certain Guglielmo Dauro, who was born around 1310 in the town of Noto. He was a merchant and landowner who became quite wealthy and influential in his community.
The surname "DAURO" also appears in some historical records from the 15th century, including a few references to members of the clergy. One example is Padre Vincenzo Dauro, a Franciscan friar who was born in Messina in 1462 and became known for his writings on theology and philosophy.
During the Renaissance period, the name "DAURO" gained some prominence in the world of art and literature. One notable figure was the poet and playwright Girolamo Dauro, who was born in Palermo in 1532. He wrote several acclaimed works, including a collection of sonnets and a tragedy titled "La Fortuna."
Another famous bearer of the surname "DAURO" was the architect and engineer Francesco Dauro, who lived in the late 16th and early 17th centuries. He was responsible for designing several important buildings and structures in Sicily, including the Church of San Domenico in Palermo and the fortifications surrounding the city of Catania.
As the surname spread beyond Sicily, it also appeared in other parts of Italy and even in some neighboring countries. For example, there are records of a family named Dauro living in the city of Naples in the 17th century, as well as a few instances of the name in parts of Spain and France during that same time period.
Demographics
Among Census respondents with the surname Dauro, the largest self-reported group is White at 95.7%. The next largest groups are Hispanic (4.3%).
The bar chart below shows how Dauro 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 Dauro surname at the time of the 2020 Census, not any inherent property of the name itself.
