Origin
Meaning and origin of Riboni
The surname Riboni has its origins in Italy, tracing back to the medieval period. It is believed to have derived from the Italian word "ribo," which means "bank" or "riverbank." This suggests that the name may have initially been associated with individuals who lived near a riverbank or worked in a profession related to waterways.
One of the earliest recorded instances of the name Riboni can be found in the Codice Diplomatico Longobardo, a collection of historical documents from the Lombard period in Italy, dating back to the 8th century. This ancient text mentions individuals with the surname Riboni, indicating the name's presence in the region during that era.
In the 12th century, the name Riboni appeared in the records of the city of Bologna, where a family bearing this surname was prominent. The Riboni family played a significant role in the political and cultural life of Bologna during the Middle Ages.
The Riboni surname has also been associated with notable individuals throughout history. One such figure was Pietro Riboni, a renowned Italian painter who lived in the 15th century. His works can be found in various churches and museums across Italy, showcasing his artistic talent and contribution to the Renaissance era.
Another prominent individual with the Riboni surname was Girolamo Riboni, a 16th-century Italian architect and engineer. He was responsible for designing and constructing several important buildings and infrastructure projects in his hometown of Venice.
In the 18th century, the Riboni family established themselves in the region of Lombardy, where they were known for their expertise in agriculture and wine production. One member of this family, Giovanni Riboni (1723-1792), became a respected figure in the world of viticulture and wrote several influential treatises on winemaking techniques.
The surname Riboni can also be traced back to the town of Riboni, located in the province of Bergamo, northern Italy. It is possible that the name originated from this specific place and was later adopted by families who migrated from the area.

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.
