Legend has it that San Mariano was once a barrio of Ilagan, the capital city of the province of Isabela. It was first named as Angela in reference to Mariano Kalingog whose family was one of the foremost settlers of the place. Angela was drowned while she was washing clothes along the Pinacanauan River. The incident brought grief to the people and her husband Mariano who also died some years later. Since then, this village teeming with fish and lush trees was known as San Mariano.
In 1920, by virtue of Executive Order 25, San Mariano became a Municipal District and with the passage of Philippines Legislature Act No. 3416 dated December 7, 1927, it was made a distinct and regular municipality.
After some years, there was an influx of migrants coming from the provinces of Ilocos, Cagayan and Pangasinan. These new settlers formed communities in tracks of agricultural lands on which they grew corn and other crops such as rice, root crops, different kinds of vegetables and bananas.
Records also show that when a German naturalist named Carl Semper hiked the Sierra Madre mountains in May 1860, he observed early inhabitants who are known today as the Kalingas. He described the said group as a typical Filipino “cultural minority” who grew their own food, practiced their own religious rites, smithed their own tools, decorated their own artifacts with distinctive designs and traded forest products for metal and salt.
On the pacific side of the mountains, Semper saw the “Negritos” and concluded that they were new arrivals because he observed no “Kalinga-Negrito” mestizos among them. They inhabited the forest close to the “Kalinga” settlements and showed up with games in seasonal periods to barter for agricultural products. Years later, some sociologists noted that there were inter-marriages entered into between these tribes.
These natives, however, were out-numbered by the mestizos or the “Ibanag-Kalinga,” the pure Ibanags and Ilocanos with a ratio of about four to one. These settlers tilled permanent farms at a place which is now known as Barangays Disulap and Minanga.
There was also an influx of several groups from the Bicol and Tagalog regions during the logging concession boom. The continuing acculturation of these groups brought about social changes in the locality. The once verdant forest slowly became barren and denuded with the ceaseless illegal logging and kaingin system employed by the local people and new migrants. When the national government decided to impose a total log ban, the ethnic groups decided to settle in the remote areas of the municipality to farm their lands. The Bicolanos and Tagalogs, on the other hand, went back to their own regions.
