I’m sure at one time or another we may have heard the terminology “Jack-Mormon.” Have you ever wonder where this may have originated from and its meaning? The Saints fled north to Clay County, Missouri after being forced out of Jackson County.
Because the settlers in Clay County took in the Latter-day Saints who had recently been pushed out of Jackson County, hostile elements in Jackson County named these sympathizers “Jack-Mormons,” a term applied in the nineteenth century to friendly non-Mormons.
