Origin
The surname Bertorelli is of Italian origin, specifically from the northern regions of Lombardy and Emilia-Romagna. It can be traced back to the late Middle Ages, around the 13th or 14th century. The name is derived from the Italian word "bertorella," which was a diminutive form of the name "Berta" or "Berto," likely referring to a person with that given name.
One of the earliest recorded instances of the name Bertorelli can be found in a document from the city of Parma in the late 14th century, where a certain Giacomo Bertorelli is mentioned as a landowner. The name also appears in various municipal records and tax rolls from cities like Milan, Piacenza, and Bologna during the Renaissance period.
In the 16th century, a prominent figure with the surname Bertorelli was Pietro Bertorelli, a renowned architect and sculptor from Modena, who was responsible for the design and construction of several churches and palaces in the region. Another notable person was Giovanni Battista Bertorelli, a 17th-century painter from Bologna, known for his religious artworks and frescoes adorning various churches in Italy.
During the 18th century, the Bertorelli family gained prominence in the world of publishing and printing. Francesco Bertorelli, born in 1737 in Parma, established a successful printing press and publishing house that produced numerous books and manuscripts. His descendant, Antonio Bertorelli (1775-1854), continued the family tradition and became a respected publisher and bookseller in Milan.
In the 19th century, the name Bertorelli was associated with the Italian Risorgimento movement, which aimed to unify the various states of the Italian peninsula. One notable figure was Valerio Bertorelli (1817-1890), a patriot and military officer from Piacenza, who fought alongside Giuseppe Garibaldi in the wars of Italian unification.
Throughout its history, the surname Bertorelli has been carried by various individuals from different walks of life, including artists, architects, publishers, and military personnel, reflecting the diverse backgrounds and contributions of those bearing this name to Italian culture and society.
Demographics
Among Census respondents with the surname Bertorelli, the largest self-reported group is White at 82.6%. The next largest groups are Hispanic (16.6%) and Black (0.4%).
The bar chart below shows how Bertorelli bearers described their own race and ethnicity on the 2020 Census form. 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 Bertorelli surname at the time of the 2020 Census, not any inherent property of the name itself.
