Based on historical accounts, the area got its name on two different versions. One version states that the place was named by a Spanish man in honor of his son Pascual who died and was buried in the place. The other version states that a Spanish man visiting the place met a settler and asked the name of the place. Not understanding what was asked of him, he thought that he is being asked of his name so he said Pascual. Later on, the place was named San Pascual by the Spaniards.

Barangay San Pascual is generally mountainous and hilly with a plain along the Gallano River at sitio Lumes. While it is a rural area, the constituents feel so very lucky because it is the only place in the municipality that was visited by then President Ferdinand E. Marcos and Mrs. Imelda R. Marcos in the 1960s who left their finger and foot prints in front of the newly constructed Marcos Prefab Building. Unfortunately, the building was blown by a strong typhoon in the later years.
