The history of the last name Isernia

The surname "ISERNIA" is of Italian origin, originating from the town of Isernia in the region of Molise, located in southern Italy. The name is believed to have derived from the Latin name "Aesernia," which was the ancient name of the town during Roman times.

Isernia is an ancient town with a rich history dating back to the 5th century BC when it was founded by the Samnites, an ancient Italic people. The town was later conquered by the Romans in the 3rd century BC and became an important Roman settlement known as "Aesernia."

One of the earliest records of the surname ISERNIA can be found in a document from the 12th century, where a nobleman named "Guglielmo di Isernia" is mentioned. This suggests that the name was already in use as a surname by that time.

In the 13th century, a renowned jurist and philosopher named Andrea d'Isernia (c. 1230-1316) was born in Isernia. He is considered one of the most important legal scholars of the medieval period and is known for his work "Commentaria in Usus Feudorum."

Another notable figure with the surname ISERNIA was Giacomo d'Isernia (c. 1300-1370), a prominent physician and philosopher who wrote several works on medicine and philosophy. He is particularly known for his work "Practica Medicinalis," which was widely used as a medical textbook in the Middle Ages.

In the 15th century, a famous artist and sculptor named Pietro d'Isernia (c. 1420-1490) was active in Naples. He is known for his work on the Cappella Palatina in the Palazzo Reale di Napoli and for his contributions to the Renaissance art movement in Italy.

The surname ISERNIA is also associated with the town of Isernia itself, which has been mentioned in various historical records and manuscripts throughout the centuries. The town's ancient name "Aesernia" can be found in the writings of Roman historians and geographers, such as Pliny the Elder and Strabo.
