Origin
Meaning and origin of Rolandelli
The surname Rolandelli is of Italian origin, with its roots tracing back to the medieval period in the regions of Lombardy and Emilia-Romagna. It is believed to have derived from the Germanic personal name "Rolant," which is a compound of the elements "hrod" (fame) and "land" (territory), essentially meaning "famous throughout the land."
One of the earliest recorded instances of the name can be found in a 12th-century manuscript from the city of Parma, where a certain "Petrus Rolandelli" is mentioned as a landowner. This suggests that the name was initially adopted by those who were associated with or descended from an individual named Rolant.
In the 13th century, records from the town of Piacenza document the presence of a noble family bearing the surname Rolandelli. This family is said to have played a significant role in the political and economic affairs of the region during that time.
During the Renaissance period, a notable figure named Antonio Rolandelli (1455-1521) gained recognition as a skilled architect and engineer. He is credited with the design and construction of several prominent buildings in the city of Bologna, including the Palazzo Malvezzi-Campeggi.
Another notable individual with this surname was Ercole Rolandelli (1570-1642), a Jesuit scholar and mathematician from Ferrara. He made significant contributions to the field of mathematics and was known for his work on algebraic equations and geometric constructions.
In the 18th century, a famous Italian composer and violinist named Francesco Rolandelli (1720-1797) rose to prominence. He was a member of the renowned Accademia Filarmonica di Bologna and composed numerous operas, concertos, and chamber works.
The Rolandelli surname has also been associated with several notable families and individuals throughout Italian history, including nobility, military leaders, and scholars. However, specific details about their lives and accomplishments are often obscured by the passage of time.

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