It was a swampy area and a docking spot for pioneering Ilocanos who settled in the upper areas of Titay. Ipil was a jumping point for their lantsa sailing to Zamboanga City. The first mayor of Ipil was Gregorio Dar an Ilocano who came from Titay. The Dar Family were the second batch of Ilocanos who settled upon the invitation of Mariano Families who are among the first batch of Ilocanos from Luzon.
The first Ilocanos used Ipil as the nearest jump point in connecting Titay with Zamboanga City. They would walk via Lumbia then to Longilog then Gabo reaching Mayabang their original settlement. It was this route that they do not have to cross the rivers as it is uphill. It was the Ilocanos who first set foot on these areas.
