The surname DIORIO has its origins in Italy, dating back to the late medieval period. It is believed to have emerged from the Italian word "d'Iorio," which means "from Iorio" or "of Iorio." The name Iorio itself is a variant of the Latin name "Georgius," meaning "farmer" or "earth-worker."

One of the earliest recorded instances of the name DIORIO can be found in the Codice Diplomatico Barese, a collection of documents from the medieval city of Bari in southern Italy, dating back to the 12th century. The name was also present in various legal and administrative records from the Kingdom of Naples during the 13th and 14th centuries.

In the 15th century, a notable figure bearing the surname DIORIO was Giacomo Diorio, a renowned jurist and legal scholar from the city of Lecce in Apulia. He authored several treatises on civil and canon law, which were widely studied in universities across Italy.

During the 16th century, the DIORIO family gained prominence in the Kingdom of Naples, with several members holding influential positions in the local government and clergy. One such figure was Girolamo Diorio (1510-1581), who served as the Archbishop of Manfredonia and played a significant role in the Counter-Reformation movement.

In the 17th century, the name DIORIO was associated with the town of Casalnuovo di Napoli, located near the city of Naples. Records from this period mention several individuals with this surname, including Antonio Diorio (1612-1678), a renowned painter and fresco artist whose works adorned numerous churches and palaces in the region.

As the DIORIO family spread throughout Italy and beyond, the name underwent various spelling variations, such as D'Iorio, Di Iorio, and DeIorio. One notable figure from this era was Giuseppe Diorio (1762-1842), a celebrated composer and violinist from Naples who performed for royalty and nobility across Europe.

In the 19th century, the DIORIO surname gained recognition in the field of literature. Enrico Diorio (1819-1892) was an Italian poet and playwright who contributed to the Romantic movement in Italian literature, while his contemporary, Vincenzo Diorio (1825-1901), was a respected author and journalist known for his works on the history and culture of Naples.
