Origin
Meaning and origin of Orsolini
The surname Orsolini is of Italian origin, with its roots traceable back to the late medieval period. It is believed to have originated in the region of Tuscany, specifically in the city of Florence. The name Orsolini is a patronymic form derived from the personal name Orso, which means "bear" in Italian.
In the 13th and 14th centuries, the Orsolini family was prominently mentioned in various historical records and manuscripts of Florence. One notable reference is found in the "Libro di Montaperti," a chronicle detailing the events of the Battle of Montaperti in 1260, where several members of the Orsolini family were listed as participants.
The earliest recorded instance of the surname Orsolini dates back to the year 1275, when a certain Bindo Orsolini was registered as a member of the Guild of Wool Merchants in Florence. This guild played a significant role in the city's flourishing textile industry during the Renaissance period.
Throughout history, several notable individuals have borne the surname Orsolini. One such person was Simone Orsolini (1450-1521), a renowned Florentine painter and architect who is best known for his work on the Church of Santa Maria delle Grazie in Arezzo.
Another prominent figure was Giovanni Battista Orsolini (1578-1649), a Jesuit scholar and educator who served as the rector of the Collegio Romano, a prestigious educational institution in Rome.
In the 18th century, Francesco Orsolini (1720-1794) gained recognition as a skilled engraver and painter, known for his intricate works depicting landscapes and architectural subjects.
During the 19th century, Giuseppe Orsolini (1819-1892) made significant contributions to the field of mathematics, serving as a professor at the University of Bologna and publishing several influential works on calculus and geometry.
The surname Orsolini can also be traced to various place names in Italy, such as the town of Orsoleo in the province of Brescia, and the village of Orsolano in the province of Piacenza, both of which may have influenced the formation of the surname in their respective regions.

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