Babatnin is the name given to this barangay which is originally a thickly forested area. It is inhabited by large number of wild animals, particularly wild pig and deer. Many inhabitants have for their living hunting these animals for food consumption.
One day, two men from a far away place came to the barrio to hunt for wild animals. They are carrying with them a hunting gear called “PANGBABATING”. While they are hunting, a group of Spaniards arrived and ask them what the name of the barrio is. Because the hunters do not understand Spanish, they are wandering what the Spaniards are asking for. So they just told the Spaniards they are using PANGBABATING”. But the Spaniards cannot pronounce it correctly so they call it BABATNIN, so from then on, the barrio was known as BABATNIN.
Babatnin has two patron Saints, San Lazaro and San Nicolas, According to the elderly folks, they have seen these two saints as the patron of the barrio since birth and only those original inhabitants can tell why they have chosen these two saints. The feast of San Nicolas is celebrated in the month of September, while San Lazaro is on Linggo de Lazaro, during the Lenten season. The original inhabitants of this barrio came from Atlag. According to elders, there was a group of Spanish soldiers who sailed between Malolos and Bulacan rivers; they saw a number of men catching crabs in this area. They ran away upon seeing the soldiers, but several of them were captured. They were made unto slaves. They were not allowed to go home, so they brought along their families in Babatnin and they became the original inhabitant of the place
