Roberto Orsini
Roberto Orsini (1295–1345) was an Italian nobleman of the Orsini family and count of Nola, the eldest son of Romano Orsini and Anastasia de Montfort, heiress of Nola. He held the office of grand justiciar of the Kingdom of Naples.
He married Sveva del Balzo, daughter of the count of Soleto; their son Niccolò was born in 1331 and inherited Nola when Roberto died early in 1345.
Through Sveva, the Del Balzo inheritance of her brother Raimondo, including Soleto, later passed to Niccolò's son Raimondello, who took the name Orsini del Balzo and founded that line of the family.
