Among the first recorded inhabitants were the families of Agustin Grefiel, Logero Ferreras, and Catato Amantillo.

Singoy Amantillo had five children: Bicario, Mauricio Enrique or "Iking," Jacobo Alyas or "Ka Buta," and Lami.

Under the leadership of Ysidro, residents considered settling in a barrio called Hilaba instead of Sitio Lipata, due to its wider land area and a hill suitable for church construction.

However, most residents retracted the proposal, citing concerns about accessibility to the shore at low tide, especially for banks.

Ultimately, Ysidro converted Sitio Lipata into the barrio Sto Niño of Basey, Samar.

In early 1949, Ysidro submitted a proposal to President Elpidio Quirino for the conversion of Barrio Sto.

The Municipality of Marabut is composed of 14 barangays: San Roque, Tag-Alag, Legaspi, Caluayan, Tinabanan, Osmena, Canyoyo, Binocyahan, Odoc, Pinana-an, and Sto.

A year later, during the term of Mayor Macario Ferreras, Poblacion Marabut was divided into four barangays: Amantillo, Sto.
