The authenticity of these stories, however, is questionable since there has never been a single piece of evidence or record that Dumi and Ingag had ever actually existed. The first non-Subanen settlers of Dumingag were from the Ilo-ilo town of Dumangas the Decolongon Family who cultivated town center area. According to more convincing sources, the earliest settlers arrived in Dumingag with renewed optimism after World War II and, starting their lives anew, they hailed the place as "Little Dumangas". Hence, this soon developed into the current name "Dumingag".
