People of this town had known many stories of how Orion got its name. Some folks say that Udyong was the first name adapted by this town. It came from the words “lu-ad” and “uryong” which meant muddy, because of the fact4 that the place was muddy and swampy during those times.
Another popular story was that during the Spanish regime, some Spanish soldiers happened to pass by this town. They did not know the name of the place so they asked the people they saw in the ricefields. One of the soldiers pointed his finger to the ground and asked “Que es el llama pueblo”. Not understanding Spanish the people thought that the soldier was referring to something he saw on the ground that happens to be a worm. The hurriedly answered “uod yon”, referring to the worm. When the soldiers heard the word, they thought that the citizens were referring to the name of the town, and left the place numbling to themselves. “Uod, uod yon”. Thus, the town was known as Udyong and was later changed to Orion.
The date of official recognition of the municipality of Orion could not be ascertained, however, records showed that this municipality was founded by a Dominican on April 30, 1667. On September 16 , 1852, a strong earthquake shook the whole archipelago and caused the destruction of the parochial church and was later rebuilt by Fr. Ulpiano Herrera, the parish priest of the place at that time. In 1892, forty years later, a big fire practically burned the whole town, that only three houses remained safe. It was Fr. Jose Campomanes who tried to reconstruct the town from the ashes and ruins of the fire and transformed it into a beautiful and prosper one. This was the beginning of the progress.
