The history of the last name DeGregorio

The surname DeGregorio has its origins in Italy, where it is believed to have emerged during the medieval period, around the 12th or 13th century. The name is derived from the Italian words "de" meaning "of" or "from," and "Gregorio," which is the Italian form of the name Gregory, derived from the Greek name "Gregorios," meaning "watchful" or "vigilant."

The earliest recorded instances of the name can be traced back to the regions of Sicily and Campania in southern Italy. It is thought that the name may have been initially adopted by individuals who lived near or were associated with a location or landmark bearing the name "Gregorio," such as a church or monastery dedicated to St. Gregory.

One of the earliest known bearers of the name was Girolamo DeGregorio, a Sicilian nobleman and politician who lived in the 15th century. Another notable figure was Antonio DeGregorio, a 16th-century Italian painter and architect from Naples, known for his works in the Mannerist style.

In the 17th century, the name appears in various records and documents from the Italian states, such as the Republic of Venice and the Papal States. A prominent individual from this time was Francesco DeGregorio, a Neapolitan lawyer and philosopher who made significant contributions to the fields of natural law and legal theory.

During the 18th century, the DeGregorio family established itself in various parts of Italy, including the regions of Lazio, Abruzzo, and Calabria. One notable member from this period was Giacomo DeGregorio, an Italian botanist and naturalist who published several works on the flora of southern Italy.

As the centuries progressed, the DeGregorio name continued to spread across Italy and beyond, with individuals bearing the surname making their mark in various fields. One such individual was Giuseppe DeGregorio, an Italian writer and journalist from the late 19th century, known for his works on Sicilian culture and history.

Despite its Italian origins, the DeGregorio surname can also be found in other parts of the world, particularly among communities with historical ties to Italy or those with Italian ancestry. However, the earliest and most prominent records of the name can be traced back to the regions of southern Italy, where it has its roots in the medieval era.
