History
In 19th century, San Isidro was formerly known as “Buwang”, a sitio with six caves that connect to Daliran Cave in Barangay Old Poblacion. During the dry season, water source became a major problem which they found hard in drilling deep wells because the water supply was very deep underground.
Because of drought, residents planned to move-out, however, a priest who lived in that area conversed them to stay and ask for help from St. Isidore through prayers for he believed that a constant prayer to St. Isidore, their request would be granted. Unexpectedly, heavy rains poured in the area. Whenever the residents were ready for planting in their farms or backyards, immediately, the rain came. So, they believed that St. Isidore granted their prayers. Hence, they changed the name of their place from “Sitio Buwang” to San Isidro. Therefore, they gave thank and celebrated their Annual Fiesta in honor of St. Isidore or “San Isidro in dialect, as their patron saint.
