Once upon a time in a barrio, there was a couple named Serafin and Clara. One night, the sweethearts had a date along the river banks rear the chapel. After their very happy moments together, suddenly very heavy rains occurred, causing the river to overflow. Large waves of water swept away Serafin and Clara, native folks tried to save them but failed. They perished together, and since then, in their memory the barrio was named KEAFIN.
One day, three Americans passed by the river in a banca. They did not know where they are. So they inquire from natives along the river, but unfortunately, they can’t understand English so they were not able to tell the foreigner the name of their place. They kept asking themselves. “Ano raw” “Ano raw”. The Americans hearing their conversations conclude that it is the name of the place they were into. Repeatedly saying those words, it sounded like ANILAO and so, from thereon, it was known as ANILAO.
It was once a part of Barangay Caingin in the early days, especially on religious practices and fiestas. Its residents cooperated wholeheartedly in having these occasions successful, from giving monetary contributions, helping in decorating then chapel, and preparing food for their visitors. But during the procession of the patron saints, the route is confined only to the central part of Caingin. So realizing the futility of their participation, they decided to form a barrio of their own. The number of houses and residents increase. They constructed their own chapel, and have the Blessed Cross as their patron. From thereon, they celebrate their own fiesta and Santa Cruzan with the early leaders of the barrio guiding them.
