Meaning and origin of Quattrocchi
The surname Quattrocchi originates from Italy, specifically from the regions of Lazio and Abruzzo. It is believed to have derived from the Italian word "quattro occhi," which translates to "four eyes," potentially referring to an ancestor who wore glasses or had a distinctive squint.
The earliest recorded instance of the name Quattrocchi can be traced back to the 15th century in the town of Amatrice, located in the province of Rieti, Lazio. A document dated 1472 mentions a certain Giovanni Quattrocchi, who was a local landowner.
In the 16th century, the name appears in various records from the town of Avezzano, in the province of L'Aquila, Abruzzo. One notable figure was Antonio Quattrocchi, a prominent merchant born in 1551, whose family had established trade routes across the Mediterranean.
The Quattrocchi name also has connections to the town of Arquata del Tronto, in the province of Ascoli Piceno, Marche. In the 17th century, a branch of the family settled in this area, and records show a Giuseppe Quattrocchi, born in 1612, who served as a local magistrate.
In the 18th century, the Quattrocchi family gained prominence in the city of Rome. Francesco Quattrocchi (1738-1819) was a renowned architect who contributed to the design of several churches and palaces in the city, including the Church of Santa Maria della Pace.
Another notable figure was Enrico Quattrocchi (1880-1958), a lawyer and politician from Rome who served as a member of the Italian parliament during the early 20th century. He was known for his advocacy of social reforms and workers' rights.
