Origin
Meaning and origin of Degruttola
The surname DEGRUTTOLA has its origins in Italy, with records dating back to the 14th century. It is believed to have originated from the Italian region of Campania, specifically the province of Avellino. The name is derived from the Italian word "grotta," meaning cave or grotto, and the prefix "de" indicating "from" or "of." This suggests that the surname may have been associated with individuals who lived near or worked in caves or grottos.
One of the earliest known references to the DEGRUTTOLA surname can be found in the historical records of the town of Monteforte Irpino, located in the Avellino province. In a document dated 1387, a certain "Giovanni DEGRUTTOLA" is mentioned as a landowner in the area.
By the 16th century, the DEGRUTTOLA family had established itself as a prominent local dynasty, with several notable members. Pietro DEGRUTTOLA (1512-1589) was a respected jurist and legal scholar who served as a judge in the courts of Naples. His son, Antonio DEGRUTTOLA (1547-1624), followed in his footsteps and became a renowned lawyer and professor of law at the University of Naples.
In the 17th century, the DEGRUTTOLA surname can be traced to the nearby town of Montemarano, where a branch of the family settled. One of the most distinguished members from this period was Francesco DEGRUTTOLA (1621-1698), a celebrated painter whose works adorned several churches and monasteries in the region.
As the DEGRUTTOLA family grew and dispersed throughout Italy, they left their mark in various fields. Vincenzo DEGRUTTOLA (1789-1862) was a notable architect who designed several notable buildings in Naples, including the Church of San Ferdinando. Giulia DEGRUTTOLA (1842-1912) was a respected educator and author who wrote extensively on the importance of women's education.
While the DEGRUTTOLA surname is predominantly Italian, it has also been found in other parts of the world due to immigration. For instance, in the late 19th century, a number of DEGRUTTOLA families migrated to Argentina, where they established themselves in the province of Mendoza, known for its wine-making industry.
Throughout its long history, the DEGRUTTOLA surname has been associated with individuals from various walks of life, including lawyers, artists, architects, educators, and landowners. Despite its relatively uncommon nature, the name has endured for centuries, carrying with it the rich cultural heritage of its Italian origins.

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
