New Harmony (Washington County). Fort Harmony was built where Harmony was established. When Harmony was flooded out, the settlers moved several miles upstream and built a new settlement, naming it New Harmony. Both were named for Harmony, Pennsylvania, where the Mormon Prophet Joseph Smith translated the Book of Mormon. The local settlers also appreciated the name because it indicated the harmony and united action the pioneers showed during their periods of trial and hardship. (John W. Van Cott)
