Pontelandolfo is an Italian town and comune in the Sannio Hills in the province of Benevento, approximately halfway between Naples and Campobasso.

[4] According to local ancient folklore, the regional surname Guerrera derived from the Latin spelling Gverrera meaning warrior or man of war, is said to have origins dating back to the soldier who died defending the bridge against the Romans.

The Guerrera clan for centuries inhabited the fertile lands south of the Alenta Creek stretching between San Lupo and Pontelandolfo centred in and around the current village of Giallonardo.

A significant number also emigrated to Australia in the period post World War 2 to the early 1970s and settled predominantly on Sydney's North Shore and Eastern Suburbs area, and whose family surnames include: Guerrera; Orsini; Mucciacciaro; Rubbo; and Mancini.

The early Australian emigrants worked in the Queensland sugar cane fields before moving to Sydney where they settled and were later joined by their extended families.
