Origin
Meaning and origin of Casciaro
The surname Casciaro originated from Italy, with its earliest known records dating back to the 16th century. It is believed to have derived from the Italian word "cascio," meaning cheese, suggesting a possible connection to cheese-making or dairy-related occupations among the early bearers of this surname.
The Casciaro name is most commonly associated with the southern Italian regions of Campania and Basilicata, particularly in the provinces of Avellino and Potenza. Some historical records indicate that the name may have originated in the town of Castelcivita, located in the province of Salerno, Campania.
One of the earliest recorded instances of the Casciaro surname can be found in the Ecclesiastical Records of the Diocese of Avellino, dating back to the late 16th century. These records mention several individuals bearing the surname, including Giovanni Casciaro, who was born in the town of Montemiletto in 1579.
In the 17th century, the Casciaro name appeared in various legal documents and land records in the Basilicata region. Notably, a certain Domenico Casciaro was a prominent landowner in the town of Melfi during this period.
The 19th century saw the emergence of several notable individuals bearing the Casciaro surname. One such individual was Francesco Casciaro (1824-1899), a celebrated Italian painter and sculptor from the town of Atripalda, Campania. His works can be found in various churches and museums throughout southern Italy.
Another notable figure was Vincenzo Casciaro (1857-1930), a renowned lawyer and politician from Potenza, Basilicata. He served as a member of the Italian Parliament and was actively involved in the political affairs of the region.
In the 20th century, the Casciaro name gained further recognition with individuals like Antonio Casciaro (1903-1985), a prominent Italian philosopher and author who contributed significantly to the field of phenomenology.
It is also worth mentioning Giuseppe Casciaro (1921-2007), a celebrated Italian architect and urban planner known for his innovative designs and contributions to the reconstruction efforts after World War II in cities like Naples and Avellino.
While the Casciaro surname may have originated from humble beginnings, it has since been carried by individuals who have left their mark across various fields, including the arts, law, politics, and academia, solidifying its place in the rich tapestry of Italian history and culture.
