Origin
Meaning and origin of Acquilano
The surname ACQUILANO originated in Italy, specifically in the region of Abruzzo. Its roots can be traced back to the 13th century, and it is believed to be derived from the Italian word "aquila," meaning "eagle." This suggests that the name was likely given to individuals who lived in areas associated with eagles or had a connection to these majestic birds.
One of the earliest recorded instances of the ACQUILANO surname can be found in the Codice Diplomatico Molisano, a collection of medieval documents from the regions of Molise and Abruzzo. In this compilation, there is a mention of a certain "Petrus de Aquilano" in a document dated 1289.
The name ACQUILANO is also closely linked to the town of Aquilonia, located in the province of Avellino, Campania. It is possible that some individuals with this surname originated from this town or had ties to the area. The town's name itself derives from the Latin word "aquila," further reinforcing the connection between the surname and the symbolic eagle.
Throughout history, several notable individuals have carried the ACQUILANO surname. One of the earliest recorded was Nicola Acquilano, a Franciscan friar who lived in the 14th century and was known for his contributions to the study of theology and philosophy. Another prominent figure was Pietro Acquilano, a 16th-century Italian artist and architect who worked on various churches and buildings in Naples and its surrounding areas.
In the 18th century, Domenico Acquilano (1708-1782) was a prominent Italian composer and violinist. He served as the Kapellmeister at the court of the Elector of Bavaria and composed several operas and instrumental works. Another individual of note was Gabriele Acquilano (1823-1899), an Italian politician and lawyer who served as a member of the Italian Parliament in the late 19th century.
One of the more recent individuals with the ACQUILANO surname was Enrico Acquilano (1919-2001), an Italian painter and sculptor known for his abstract expressionist works. He studied at the Academy of Fine Arts in Naples and exhibited his art in numerous galleries throughout Italy and other European countries.
While the ACQUILANO surname may not be as widespread as some other Italian surnames, its history and connections to the symbolic eagle, as well as its geographical origins in Abruzzo and Campania, make it a distinctive and intriguing name with deep roots in Italian culture and heritage.

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.
