Before the coming of the Spaniards, the settlement was called "Pamagpagan" because of the way the native inhabitants left their hair in disarray.

Eusebio Ibanez, organized the settlement into a town and was transferred from Guinbaya-an to its present site.

As a token of gratitude, the inhabitants called the town "Pastrana" in honor of Fr.

He was assisted in the administration of the pueblo by the "Guinhaupan," a group of men equivalent to the present councilors, by the "tenientes" and by the "Cabezas de barangay."

When the Philippine revolution broke out in 1898, the people fled to the mountains and for a time, the local government then headed by Andres Villablanca, was temporarily suspended.

In 1912, Agaton Villablanca worked for the establishment of the barrio to a municipality so that its former status was finally regained.

In 1944 when the American liberation forces drove out the Japanese, Francisco Villablanca, who was the pre-war mayor, automatically resumed his position and under him, the town was restored to its former status as a peaceful community.
