Origin
Meaning and origin of Daurelio
The surname Daurelio has its origins in Italy, emerging during the medieval period. It is believed to have derived from the Old Latin word "daurus," meaning "oak tree," suggesting that the name's bearers may have once lived near a prominent oak grove or forest.
One of the earliest recorded instances of the name can be traced back to the 12th century, when a certain Guglielmo Daurelio was mentioned in a document from the Tuscan city of Siena. This record suggests that the Daurelio family may have its roots in the region of Tuscany.
By the 13th century, the name had spread to other parts of Italy, with records indicating a Gherardo Daurelio residing in the city of Bologna. This individual's presence in a prominent university town implies that members of the Daurelio family may have been involved in scholarly pursuits or held positions within the academic community.
The Daurelio name gained further prominence in the 15th century, when a notable physician named Giovanni Daurelio (1420-1492) practiced in the city of Naples. His contributions to the field of medicine and his association with the royal court of the Kingdom of Naples brought recognition to the family name.
During the Renaissance period, a renowned artist and sculptor named Vincenzo Daurelio (1490-1576) gained acclaim for his work in various Italian cities, including Rome and Florence. His sculptures and architectural designs can still be found adorning churches and public buildings throughout Italy.
Another noteworthy figure was Tommaso Daurelio (1530-1612), a Venetian diplomat and statesman who served as an ambassador for the Republic of Venice in several European courts. His diplomatic efforts and negotiation skills were highly regarded during his time.
While the Daurelio surname may not have been as widely documented as some other Italian family names, its presence throughout history in various regions of Italy and across different professions and social strata suggests a long-standing legacy and a significant contribution to the cultural fabric of the country.

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