<P> Several LDS historians believe that the term was used prior to Sharp 's mention , and has ties to sympathetic Democrats in Jackson County , Missouri . Their belief is that the term originated in Missouri , during the Kirtland period of Latter Day Saint history , circa 1834 . When Church members were expelled from Jackson County by a mob , many fled to Clay County , where local citizens , mostly Democrats , were sympathetic and friendly toward the Mormons . These citizens were pejoratively labeled `` Jack '' Mormons by the antagonistic citizens of Jackson County . </P>
