Origin
Meaning and origin of Bertolina
The surname Bertolina has its origins in Italy, with the first recorded instances dating back to the 14th century. It is believed to be a locational name, derived from the Italian town of Bertoli, located in the province of Pavia, Lombardy. The name likely originated as a way to distinguish individuals who hailed from this particular town.
One of the earliest documented references to the surname Bertolina can be found in a medieval manuscript from 1387, which mentions a certain Giacomo Bertolina, a merchant from the city of Milan. This record suggests that the name had already established itself as a recognized surname by that point.
In the 16th century, a notable figure bearing the surname Bertolina was Giovanni Battista Bertolina, a renowned painter and architect who lived from 1525 to 1598. His works can still be admired in various churches and buildings throughout northern Italy, particularly in the city of Genoa.
Another individual of note was Antonio Bertolina, a philosopher and scholar who lived during the 17th century (1630-1701). He was widely respected for his contributions to the fields of ethics and moral philosophy, and his writings were influential in academic circles of the time.
During the 18th century, the Bertolina family produced a celebrated military leader in the form of Girolamo Bertolina (1718-1789). He rose through the ranks of the Venetian army and played a pivotal role in several battles against the Ottoman Empire, earning him widespread recognition and respect.
Moving into the 19th century, the name Bertolina is associated with Pietro Bertolina (1804-1878), a prominent Italian politician who served as a member of the Sardinian Parliament and was instrumental in the unification of Italy under the House of Savoy.
While the surname Bertolina may not be as widespread as some other Italian names, it has a rich history that spans several centuries and encompasses individuals from various walks of life, including artists, scholars, military leaders, and politicians.

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