Origin
Meaning and origin of Mondelli
The surname Mondelli originated in Italy, with the earliest records dating back to the 13th century. It is believed to have derived from the Italian word "mondo," meaning "world" or "universe," combined with the diminutive suffix "-elli," suggesting a possible connection to a place name or occupation related to the broader world or a particular region.
One of the earliest documented mentions of the Mondelli name can be found in the archives of the city of Florence, where a family bearing this surname was recorded in the year 1287. This suggests that the name may have its roots in the Tuscan region of central Italy, where Florence is located.
During the Renaissance period, several notable individuals with the Mondelli surname emerged. One such figure was Girolamo Mondelli (1510-1579), a renowned Italian sculptor and architect who contributed to the design and construction of several churches and palaces in Rome and other Italian cities.
Another prominent Mondelli was Antonio Mondelli (1632-1708), a Venetian painter known for his religious works and portraits. His paintings can be found in various churches and galleries throughout Venice and the surrounding regions.
In the 18th century, the Mondelli name gained recognition in the field of music with the composer and violinist Giovanni Battista Mondelli (1745-1821). He was celebrated for his compositions and performances throughout Italy and parts of Europe.
Moving into the 19th century, a notable figure was Cesare Mondelli (1818-1892), an Italian politician and lawyer who served as a member of the Italian parliament and played a role in the unification of Italy.
Throughout the centuries, the Mondelli surname has also been associated with various place names and their older spellings. For instance, in the region of Emilia-Romagna, there is a small town called Mondelli, which may have influenced the surname's origin or vice versa.
While the Mondelli name has its roots in Italy, it has since spread to other parts of the world through migration and intermarriage. However, its historical significance remains deeply rooted in the Italian peninsula, where it has left an indelible mark across various fields, from art and architecture to music and politics.

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.
