Origin
Meaning and origin of Radano
The surname RADANO is of Italian origin, with its roots tracing back to the 14th century. It is believed to have originated in the southern regions of Italy, particularly in the vicinity of Naples and the surrounding areas.
The name RADANO is likely derived from the Italian word "rada," which means a small bay or cove. This suggests that the earliest bearers of this surname may have lived near or had some connection to a coastal area characterized by small inlets or harbors.
One of the earliest recorded instances of the RADANO surname can be found in the "Codice Diplomatico Barese," a collection of medieval documents from the city of Bari, dating back to the 14th century. In these records, the name appears in various spellings, such as "Radanus" and "Radano."
During the Renaissance period, the RADANO name gained prominence in the arts and literature. Notably, Girolamo Radano, a 16th-century Italian poet and scholar born in Naples in 1520, was known for his works in Latin and Italian. His birth and death dates are recorded as 1520-1592.
Another notable figure bearing the RADANO surname was Ottavio Radano, an Italian painter active in the late 16th and early 17th centuries. He was born in Naples around 1570 and is renowned for his religious and mythological works, which can be found in various churches and collections throughout Italy.
In the 18th century, the RADANO name appeared in the records of the Kingdom of Naples, with several individuals bearing this surname holding positions of prominence within the local government and clergy. One such individual was Vincenzo Radano, a respected jurist and legal scholar who served as a judge in the Royal Court of Naples in the mid-18th century.
Moving into the 19th century, the RADANO surname gained recognition in the field of medicine. Giuseppe Radano, born in Bari in 1815, was a renowned physician and professor of medicine at the University of Naples. His contributions to the study of infectious diseases and public health were widely acclaimed during his lifetime (1815-1892).
Throughout its history, the RADANO surname has also been associated with various place names in Italy, such as Radano, a small town in the province of Avellino, and Radanovia, a locality in the province of Salerno. These place names may have influenced the evolution and spread of the surname across different regions of Italy.

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