Origin
Meaning and origin of Boglioli
The surname Boglioli is of Italian origin, with its roots traced back to the northern regions of the country, particularly in the areas around Milan and Lombardy. It is believed to have derived from the Italian word "boglio," which means "boil" or "bubble," potentially referring to an occupation or a place name associated with hot springs or bubbling water sources.
One of the earliest recorded instances of the Boglioli name can be found in the historical records of the city of Milan, dating back to the late 13th century. In a document from 1287, a certain Guglielmo Boglioli is mentioned as a landowner and a prominent figure in the local community.
During the Renaissance period, the Boglioli family gained recognition as skilled artisans and craftsmen. One notable individual was Giacomo Boglioli, a renowned goldsmith who lived in the 15th century and created intricate works of art for noble families and the Milanese court.
In the 17th century, the Boglioli name appears in the annals of the city of Bergamo, where a branch of the family had settled. Antonio Boglioli, born in 1635, was a respected lawyer and legal scholar who authored several treatises on civil law and judicial procedures.
The 18th century saw the rise of a prominent Boglioli family in the area of Parma. Pietro Boglioli (1712-1789) was a highly regarded architect who designed several churches and public buildings in the region, including the iconic Basilica della Steccata in Parma.
As the Boglioli name spread across Italy, it also gained recognition in other fields. One notable figure was Giuseppe Boglioli (1827-1909), a celebrated painter from Milan who was known for his landscapes and portraits. His works can be found in various museums and private collections throughout Italy.
While the Boglioli surname has its roots in northern Italy, it has since spread to other regions and countries, with individuals bearing this name making significant contributions in various fields throughout history.

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