The history of the last name Alonzi

The surname Alonzi has its origins in Italy, specifically in the central region of Lazio. It is believed to have emerged during the medieval period, around the 11th or 12th century. The name is derived from the Latin name "Aloncius" or "Aluncius," which was a personal name used in ancient Rome.

One of the earliest recorded instances of the name Alonzi can be found in a document from the 13th century, where it was mentioned in relation to a landowner from the town of Alatri, located in the province of Frosinone. This suggests that the name may have originated in that area and later spread to other regions.

During the Renaissance period, the name Alonzi appeared in various historical records, including birth and marriage registers in cities such as Rome and Viterbo. One notable bearer of the name was Pietro Alonzi, a Roman scholar and philosopher who lived in the 16th century (c. 1500-1570).

In the 18th century, the Alonzi family gained prominence in the town of Arpino, located in the province of Frosinone. A prominent member of this family was Domenico Alonzi (1735-1812), a renowned architect and engineer who designed several churches and palaces in the region.

Another notable figure with the surname Alonzi was Vincenzo Alonzi (1808-1868), an Italian painter and engraver who was born in Campobasso, in the region of Molise. His works can be found in various museums and galleries across Italy.

In the 19th century, the Alonzi name was associated with the town of Alatri once again. One of the most influential figures from this era was Nicola Alonzi (1845-1921), a lawyer and politician who served as the mayor of Alatri and later as a member of the Italian parliament.

Throughout history, the surname Alonzi has also been found in various spellings, such as Alonzo, Alonsi, and Alonzio, reflecting regional variations and linguistic influences. While the name is primarily concentrated in central Italy, particularly in the regions of Lazio and Molise, it has also spread to other parts of the country and beyond due to migration and intermarriage.
