San Isidro as it is known today was originally called Macañawed derived from gawed, the local name of vines, the leaves of which are chewed by old folks with betel nuts, tobacco leaves and shell lime (apog).
This plant grew abundantly in the place during the old times and provided sufficient supply to the customary nganga habit of their ancestors; hence this place was known as "Macañawed from the edible vine, gawed".

As time goes by, people from different places lured the rich agricultural potential and vast area of the place, continuously migrated to Macañawed until there was a merger of inhabitant (Ilocanos, Tagalogs, Igorots, Kapampangans and others), Macañawed gradually became quickly populated and farming became the main source of livelihood because of its fertile soil.

The inhabitants believed that to attain bountiful harvest and peaceful atmosphere, they need to have a patron saint.
They chose San Isidro Labrador, the patron saint of farmers, whom they honor during their fiesta celebration.
Gradually, the people began to call Macañawed as San Isidro.
