There were stories that it was named for Captain Robert Lyon, a survivor of the Pyramid Lake War in 1860, but Nevada State Archives staff discovered a county seal with the picture of the Civil War general, settling the conflict Yerington (1911) for H. M. Yerington, one of the builders of the Virginia Truckee Railroad.
