I have little knowledge of the history of Pangasinan but it is recorded that Aringay was a town of Pangasinan before La Union was formed in 1850, when the colonial government merged the southern town of Ilocos Sur, the northern towns of Pangasinan, and the western towns of Benguet to the east.
Aringay Pangasinan is now the area of Caba or Aringay, La Union.
