Long before the Spanish occupation took over the country. Aetas from certain places like Flora, Sapangcawayan, Manabayucan, and Cawayan Bugtong – now known collectively as Barangay Maruglu – go on trips at least once a month to trade goods at the lowlands of Patling (O’Donnell).
As the folklore entailed, just near Patling or on the other side of the creek, Aetas used to rest in a certain wooded place in the course of their trek to the lowland and back. As told in the story, the time came that some of them built shacks for better rest and cooking but unfortunately, this place eventually became a rendezvous for gamblers and other vices that failed to halt for some time.
Soon after, a certain disease hit the place and Aetas sought aid from lowlanders and were given advice by a certain old lowlander man to make tea out of a grass called “allabon”, which were abundant in the area. Hence, some people called the place as “Mallabon.”
On the verge of World War II in the country, Aetas resorted to living in Mallabon when Japanese soldiers invaded their homes in the mountains. Later, hunger reigned over the place when Americans fled after the war, leaving the unfortunate Aetas and other Mallabon settlers in famine.
Years after while the population was under the progression of recovery, “Mallabon” was officially named “Sampucao” in the integrity of their losses. The etymology of which came from two words “Sam” and “Pucao”. As the folklore supposed, “Sam” came from the word “San” as Filipinos refer to “Saints”, while “Pucao” is an assumed Ilocano word which means “lost”, hence, Sampucao.
Through time, the name Sampucao was changed to “Maruglu”, and the story of why and how it was changed remains hazy up to date as there were no proven and verified data to claim it.
Today, Barangay Maruglu is the home of the municipality’s largest Aeta community engaged in agriculture, taro, and other roots crop farming and a modest Eco Park for tourists with great interests in horseback riding, nature, and community immersion.
