Origin
Meaning and origin of Mangelli
The surname Mangelli is of Italian origin, with roots tracing back to the 14th century. The name is derived from the Latin term "manganum," which referred to a type of medieval siege engine or catapult. It is believed that the name was initially given to individuals who were associated with the construction or operation of these military machines.
The earliest recorded instances of the name Mangelli can be found in historic documents from the regions of Tuscany and Emilia-Romagna. In these areas, the name was often spelled as "Mangelli" or the variations "Mangello" and "Mangielli." These spellings were influenced by the local dialects and linguistic traditions prevalent at the time.
One of the earliest known bearers of the name was Giovanni Mangelli, a skilled engineer and architect who lived in the city of Florence during the late 15th century. Giovanni was renowned for his expertise in the design and construction of fortifications and defensive structures, which likely contributed to the association of the name with military engineering.
In the 16th century, the Mangelli family gained prominence in the city of Bologna, where they were involved in various trades and professions. Notably, Giacomo Mangelli (1532-1612) was a respected lawyer and legal scholar who authored several influential treatises on civil law.
During the 17th century, the name Mangelli spread to other parts of Italy, including the regions of Veneto and Lombardy. In Venice, a branch of the family established itself as successful merchants and traders, contributing to the city's renowned maritime and commercial activities.
One of the most notable figures bearing the Mangelli name was Girolamo Mangelli (1677-1739), a Bolognese painter who gained recognition for his religious and mythological works. His paintings can be found in various churches and galleries across Italy, showcasing his skill and artistic talent.
Another prominent individual was Carlo Mangelli (1823-1892), an Italian engineer and architect who played a significant role in the development of modern infrastructure in Italy. He was responsible for the design and construction of several bridges, railways, and public buildings, leaving a lasting impact on the country's landscape and infrastructure.
Throughout history, the surname Mangelli has been associated with individuals from diverse backgrounds, including engineers, architects, lawyers, merchants, and artists. While the name may have originated from a connection to military engineering, it has since branched out to encompass various professions and pursuits.

The bar chart below shows how Mangelli 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 Mangelli surname at the time of the 2020 Census, not any inherent property of the name itself.
