The history of the last name Iorio

The surname IORIO originated in Italy, with its earliest known roots tracing back to the 12th century in the region of Campania. The name is derived from the Latin word "Horius," meaning "gardener" or "keeper of the garden." This suggests that the original bearers of the surname were likely involved in agricultural or horticultural professions.

The earliest recorded instances of the name can be found in historical documents from the city of Naples and its surrounding areas. In the 13th century, a nobleman named Guglielmo Iorio was mentioned in a manuscript detailing the ownership of land and properties within the Kingdom of Naples.

During the Renaissance period, the Iorio family gained prominence in the city of Salerno, where they were involved in various industries and trades. One notable figure from this time was Girolamo Iorio, a wealthy merchant and banker who lived from 1520 to 1585.

In the 17th century, the Iorio name appeared in the records of the Catholic Church, with several priests and clergy members bearing the surname. One such individual was Monsignor Domenico Iorio, who served as the Bishop of Avellino from 1642 to 1666.

As the Iorio family spread throughout Italy, they established roots in different regions, including Puglia, Calabria, and Sicily. In the 19th century, a famous architect named Gaetano Iorio was born in Palermo, Sicily. He designed many notable buildings in the city, including the Church of San Giuseppe dei Teatini, which was completed in 1872.

Another notable figure was Vincenzo Iorio, a military officer and politician from Naples who lived from 1835 to 1910. He served as a general in the Italian army and was later elected as a member of the Italian Parliament, representing his hometown.

Over the centuries, the Iorio surname has also been associated with various place names and locations within Italy. For example, there is a small town called Iorio in the province of Pavia, which may have derived its name from the surname or vice versa.
