Shortly before the Spaniards settled at Looc where now stands the poblacion, Inggo Bayon died, leaving many mangyans and aetas in his colony. He was succeeded by a Mangyan named Suli-an. The whole dominion of Late Inggo Bayon was renamed Suli after his successor’s who did not last longer than that of Inggo Bayon. This period is reckoned from the year 1630, or about 110 years after Magellan set foot in the Philippines up to 1655. Suli- an was atrocious to his subjects. So the mangyans sailed away and took refuge in Mindoro while the aetas went to carabao Island (Hambil). When Suli- an died, a hybrid mangyan-eatas named Ayo’ succeeded him. Then the place was renamed Ayo’. Intermarriage between the remaining mangyans and the eatas was allowed, and when Ayo’ died, he was succeeded by Etong who was converted to Christianity and was baptized by a friar, Father Paulino Jimenez, with the name Evangelista. Since then, many more were proselyte so that in the course of time, Juan Nepomuceno became the barrio lieutenant in 1883, or about 16 years before the Americans encamped at Looc. It was during Nepomuceno’s period that a formal founding of the village or minuro’ began to form in shape in the sitio of Sawang with Capitan Hugo Gabuna as his promoter.

     In the past, this place bore the name Agoho as called by the Mangyan Chief Inggo Bayon due to the presence of innumerable agoho trees which grew ubiquitously in the locality. Dalipi, Sawang, Datag, Ilawod, Suong, Ingkiyangan, Agpakol, Guinpasilan and a protion of Campong are the sitios of Agoho which are divided into smaller hamlets. This barrio is located on a peninsula southwest of Looc poblacion across the bay.

     From an ancient memoir, it was gleaned that the submerged coral island in the middle of the Looc bay were now stands the nautical beckon light tower was a floating islands with few inhabitants. Due to a strong earthquake followed by mighty billows, a huge quantity of sand from this island was carried by the water current to the eastern shore of the peninsula of Agojo called Sawang, now called Dapdap. The island thereafter, became a depopulated sunken coral barrier reef. This reef affords an excellent mooring of wrecking boats flying between the poblacion and Agojo across the bay.
