Origin
The surname Bertelli originated in Italy, where it first appeared as an occupational name for someone who worked as a carter or wagon driver. It derives from the Italian word "berta", which referred to a type of wagon or cart. The earliest known bearer of the name was Guglielmo Bertelli, who lived in Florence in the late 13th century.
The Bertelli name is most closely associated with the Emilia-Romagna region of northern Italy, particularly the cities of Bologna and Modena. In the 14th century, the Bertelli family was among the most influential noble families in Bologna, with several members serving as city councilors and ambassadors.
One of the earliest recorded examples of the Bertelli name dates back to 1311, when a certain Berto Bertelli is mentioned in the archives of the city of Modena. Another notable early bearer of the name was Giovanni Bertelli, a renowned painter who lived in Bologna in the late 15th century.
The Bertelli surname can also be found in historical records from other parts of Italy, such as Tuscany and Lombardy. In the 16th century, a branch of the Bertelli family settled in Venice, where they became respected merchants and traders.
Notable people with the Bertelli surname throughout history include:
1. Antonio Bertelli (1518-1594), an Italian historian and author from Modena.
2. Ferdinando Bertelli (1825-1909), an Italian politician and journalist from Bologna.
3. Virgilio Bertelli (1864-1938), an Italian engineer and industrialist, founder of the Bertelli Motorcycle Company.
4. Gino Bertelli (1914-1995), an Italian racing driver and constructor of sports cars.
5. Pier Luigi Bertelli (1941-2017), an Italian fashion designer and co-founder of the luxury brand Diesel.
While the Bertelli name has its roots in northern Italy, it has since spread to other parts of the country and beyond, with descendants of the original Bertelli families now found in various regions and countries around the world.
Demographics
Among Census respondents with the surname Bertelli, the largest self-reported group is White at 93.9%. The next largest groups are Two or More Races (2.7%) and Black (1.7%).
The bar chart below shows how Bertelli 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 Bertelli surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
