In the early days before the arrival of the Spaniards to our country, and during the rule of the datus and rajas, there was once a brave datu by the name Juan. Whenever this datu went out of his place, he always wears a body protector called cabal in the dialect. This datu was very powerful, he was also kind to his people, and they loved him very much. When he died, the people became sad. They named their barangay Juancabal in honor of their brave ruler. Until later on, the name Juancabal was change to Cuancabal.
Barangay Cuancabal is located two kilometers southeast of the town proper. The national road going to Manila traversed at the western side.
