The Orsini family is an Italian noble family; it was one of the most influential princely families in medieval Italy and renaissance Rome.

Romano Orsini (1268-1327), called Romanello, was Royal Vicar of Rome in 1326, and inherited the countship of Soana through his marriage with Anastasia de Montfort, Countess of Nola. Her line goes back to Simon de Montfort and Eleanor, of England, the daughter of King John and Isabel de Angoulême.

Romano's son Roberto (1295-1345), married Sibilla del Balzo, daughter of the Great Senechal of the Kingdom of Naples. Among his sons, Giacomo (died 13 August 1379; Dean of Salisbury, Archdeacon of Leicester and Archdeacon of Durham) was created cardinal by Gregory XI in 1371, while Nicola (August 27, 1331-February 14, 1399) obtained the counties of Ariano and Celano. The latter was also Senator of Rome from 27 August 1331 to 14 February 1399 and enlarged the family territories in Lazio and Tuscany.

As to his title as Count of Nola, it was held by Guy de Montfort, son of Simon de Montfort, 6th Earl of Leicester and Eleanor of England, the daughter of King John and Isabel de Angoulême as the County of Nola and was inherited by his eldest daughter's Orsini husband and then held by members of their family. Nola is an ancient Campanian town, on the plain between Mount Vesuvius and the Apennines near Naples.
