History

San Antonio as a pueblo or municipality was organized on May 12, 1849 as a result of two petitions made for its  separation from the town of San Narciso. The said petitions were made in 1848 and on March 8, 1849. It was signed by 31 top leaders of the community headed by Don Vicente Lacuesta, who was elevated from Teniente Primero to Teniento Absoluto. Its name changed to San Antonio, in honor of Sr. Don Urbiztondo, who was the “Captain General” of the Philippine Archipelago.

Based on the official history of the town written on October 14, 1913, in compliance with Executive Order No. 1 of 1911, the first Ilocano families from the Paoay area of Ilocos Norte who arrived in the year 1830 and founded the first settlement that grew and developed into what now called town of San Antonio. Records further disclosed that the site of the first community is somewhere near barrio Currilapa, now Barangay Antipolo. The first settlers, on their arrival found on this place a family of Aetas and later met a hunter of deer in the area named Don Salavador dela Cruz, a prominent resident of the pueblo of Cabangan.

The village was first called PAMALISARAOAN and which was later known as PAMISAROAN was given the status of a barrio of Uguit (Castillejos) in the 1830’s. However in the year 1846, the barrio of Alasais or Aluciis, which belonged to Cabangan, was made into a new pueblo, now called San Narciso. Barrio Pamisaraon was detached from Uguit and was subsequently attached to San Narciso.
