In early 16th to 17th centuries, the “Id-dules” (Aetas or Baluga) and Egongots (Ilongots) tribe inhabited the southern Sierra Madre and Caraballo Mountains. Pantabangan (Pantabanganan in early 18th century) may have came from the root Ilongot word "Sabangan or Sabanganan" that means "junction of water streams". It was learned that most of the places in Central Luzon were derived from Ilongot word like Caanaoan, Puncan, Cadanglaan (now Carranglan), Kabaritan (Now San Jose City) and others. Bungamong (Bongabon) and Cadanglaan was formerly sitio of Pantabangan and Kabaritan also part of Pantabangan.
