Origin
Meaning and origin of Bauso
The surname Bauso has its origins in Italy, specifically in the regions of Sicily and Calabria. It is believed to have emerged during the medieval period, likely between the 11th and 13th centuries.
One theory suggests that Bauso may derive from the Latin word "bausus," which means "tawny" or "reddish-brown." This could indicate that the name was initially used as a nickname for someone with reddish-brown hair or complexion. Another possibility is that it originated from a place name or geographic location, as many Italian surnames were derived from the names of towns or regions.
Early mentions of the name Bauso can be found in historical records from Sicily and Calabria. For instance, a document from the 14th century in the city of Messina refers to a certain "Giovanni Bauso," indicating the presence of this surname in that region during that time period.
One of the earliest recorded individuals with the surname Bauso was Tommaso Bauso, who lived in Palermo, Sicily, in the late 15th century. He was a prominent merchant and landowner, and his descendants continued to bear the Bauso name in the following centuries.
In the 16th century, a notable figure named Antonio Bauso (1520-1587) from Reggio Calabria was a renowned scholar and philosopher. He wrote several treatises on philosophy and theology, contributing to the intellectual discourse of his time.
During the 17th century, the Bauso family had a strong presence in the town of Scilla, located in the province of Reggio Calabria. One member, Giuseppe Bauso (1645-1712), was a respected lawyer and judge who served in the local courts.
Another significant individual with the surname Bauso was Vincenzo Bauso (1770-1845), a military officer from Messina who fought in the Napoleonic Wars. He rose through the ranks and was eventually awarded the prestigious title of Cavaliere (Knight) for his bravery and service.
In the 19th century, a prominent artist named Francesco Bauso (1810-1892) hailed from Palermo. He was a talented painter and sculptor, known for his religious works that adorned many churches throughout Sicily.
These are just a few examples of notable individuals with the surname Bauso throughout history, showcasing the name's presence and significance in various regions of Italy, particularly in Sicily and Calabria.

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.
