Origin
Meaning and origin of Bertollini
The surname Bertollini has its origins in Italy, specifically in the northern regions of Lombardy and Veneto. It likely emerged during the late Middle Ages, around the 13th or 14th century. The name is believed to be derived from the Italian personal name "Bertolino," which itself is a diminutive form of the Germanic name "Berthold," meaning "bright ruler" or "brilliant ruler."
One of the earliest recorded instances of the Bertollini surname can be found in a document from the city of Verona, dated 1326, which mentions a certain "Iohannes Bertollini." This suggests that the name was already well-established in the region by that time. Additionally, there are records from the 15th century that refer to a family called "Bertollini" residing in the town of Bergamo, located in Lombardy.
In the 16th century, a notable figure bearing the Bertollini surname was Gian Domenico Bertollini (1555-1623), a Italian jurist and professor of law at the University of Padua. His works on legal matters were widely influential during his time. Another prominent individual with this surname was Giulio Bertollini (1678-1746), a Venetian painter known for his religious and mythological works.
During the 17th and 18th centuries, the Bertollini surname continued to be found in various parts of northern Italy, with families bearing this name residing in cities such as Milan, Brescia, and Vicenza. One noteworthy example from this period is Pietro Bertollini (1701-1778), a renowned architect who designed several churches and palaces in the Veneto region.
In the 19th century, the Bertollini surname gained further prominence with individuals like Giuseppe Bertollini (1822-1899), an Italian sculptor and medalist who created works for the Vatican and other prestigious patrons. Another notable figure was Vincenzo Bertollini (1836-1912), a successful banker and philanthropist from Verona, who founded several charitable institutions in his hometown.
Throughout its history, the Bertollini surname has been associated with various professions and fields, ranging from law and academia to the arts and finance. While the name is predominantly found in Italy, it has also spread to other parts of the world due to immigration patterns.

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.
