Origin
Meaning and origin of Pedroli
The surname PEDROLI has its origins in Italy, with the earliest records dating back to the 13th century. It is believed to have originated from the northern regions of the country, particularly in the areas surrounding the cities of Bergamo and Brescia.
The name PEDROLI is derived from the Italian word "pedroli," which means "small stone" or "pebble." This suggests that the name may have been initially given to someone who lived near a stony area or worked as a stonemason or quarry worker.
One of the earliest recorded instances of the name PEDROLI can be found in a document from the town of Alzano Lombardo, near Bergamo, dated 1278. The document mentions a certain "Petrus Pedroli" as a landowner in the area.
Another notable early reference to the PEDROLI name is in the records of the Cathedral of Santa Maria Maggiore in Bergamo, which mention a "Giovanni Pedroli" as a stonemason who worked on the construction of the cathedral in the late 15th century.
In the 16th century, the PEDROLI name became more widespread throughout northern Italy, with several individuals bearing the name appearing in various records and documents from the regions of Lombardy, Veneto, and Emilia-Romagna.
One of the earliest notable figures with the surname PEDROLI was Alessandro Pedroli, a renowned painter and sculptor from Bergamo who lived from 1542 to 1612. His works can still be found in several churches and museums in northern Italy.
Another prominent individual with the PEDROLI name was Giacomo Pedroli, a philosopher and theologian who was born in Brescia in 1624 and died in 1697. He authored several influential works on moral philosophy and theology during his lifetime.
In the 18th century, the PEDROLI name gained prominence in the field of medicine, with Antonio Pedroli (1718-1792) being a renowned physician and professor of anatomy at the University of Padua.
During the 19th century, the PEDROLI name was associated with various influential figures, including Giuseppe Pedroli (1821-1895), a successful entrepreneur and industrialist from Milan, and Cesare Pedroli (1856-1931), a renowned Italian architect who designed several notable buildings in Milan and other cities in northern Italy.
Despite its origins in northern Italy, the PEDROLI surname has since spread to other parts of the country and even beyond, with individuals bearing this name found in various countries around the world today.

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