Origin
The surname Rosanelli has its origins in Italy, specifically in the region of Tuscany. It is believed to have emerged during the Middle Ages, around the 13th or 14th century. The name is derived from the Italian word "rosa," meaning rose, and is likely an occupational surname given to those who cultivated or traded roses.
One of the earliest recorded instances of the name Rosanelli dates back to the 15th century in the city of Florence. In a document from the year 1436, a certain Giovanni Rosanelli is mentioned as a prominent merchant and landowner. This suggests that the family had already established itself as a respected and prosperous lineage by that time.
During the Renaissance period, the Rosanelli family played a significant role in the cultural and artistic life of Florence. Notably, Piero Rosanelli (1458-1521) was a renowned painter and sculptor who contributed to the embellishment of several churches and palaces in the city. His works can still be admired today, showcasing the family's commitment to the arts.
In the 17th century, another member of the Rosanelli family, Antonio Rosanelli (1631-1698), gained recognition as a prominent jurist and legal scholar. He authored several influential treatises on Roman law and served as a judge in the Florentine court system.
The name Rosanelli also has connections to the nearby town of Rosano, located in the province of Florence. It is possible that some branches of the family may have originated from this region, contributing to the development of the surname.
Another notable individual bearing the Rosanelli surname was Girolamo Rosanelli (1789-1857), a Italian politician and diplomat who served as a minister plenipotentiary for the Grand Duchy of Tuscany. He played a crucial role in negotiating various treaties and agreements during his diplomatic career.
Throughout the centuries, the Rosanelli family has produced numerous other individuals who have left their mark in various fields, including literature, academia, and the arts. However, due to the scope of this report, it is not possible to include detailed accounts of all notable figures associated with this surname.
Demographics

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