Saint Emidius or Emygdius (died ca. 303) was patron saint of the city of Naples and gained his association with earthquakes after a series of shocks there in 1731. He was favored in California by the missionaries and his feast day was observed after the Fort Tejon earthquake of 9 January 1857; it is possible that the San Emigdio Mountains near Fort Tejon were named at the same time (as was the adjacent Temblor Range).
