Sims Lafayette Matheny, his personal and family background, and his involvement in the Mountain Meadows Massacre
Sims L. Matheny
1833-1881
Biographical Sketch
'[There is uncertainty whether Sims Matheny participated in the Mountain Meadows Massacre or was on the ground when the Arkansas company was initially attacked or besieged.]
Sims Lafayette Matheny was a native of Tennessee with forebears in Virginia and South Carolina. Over his lifetime he moved from Tennessee to Arkansas and then Texas before settling in frontier Utah. He was an American frontiersman and pioneer in southern Utah.
Early Years in the American South
Matheny’s parents were in Monroe, Mississippi before moving to Tennessee where Matheny was born. In the late 1830s they moved to Green County, Arkansas and by the early 1840s they had moved to Montgomery County in Texas territory, later the Republic of Texas.
Migration to Utah
In the 1850s the Mathenys immigrated to Utah territory, some of them settling in Fillmore, Millard County in central Utah. In 1855, Matheny married Ellen Barton Ray, (1839-1920) a native of Mississippi.

Joining the Southerners in Washington County and the Cotton Mission
In spring 1857, Matheny and his wife had joined the colony of Southerners in the new settlement in Washington County in the southwestern corner of Utah. These southerners founded the new settlement of Washington and were instrumental in establishing the Cotton Mission and cotton culture in what came to be known as Utah's Dixie.
Although the Cotton Mission eventually proved commercially unsuccessful, it did succeed in producing cotton goods for local use and export at an important stage in Utah Territory's economic development.
In the Iron Military District: Sergeant Sims Matheny, Company I, John D. Lee's 4th Battalion
In September 1857, 24-year-old Sims Matheny was a sergeant of the first Washington platoon in Company I of John D. Lee’s 4th Battalion. See A Basic Account for a full description of the massacre.
He was listed in the 1859 federal arrest warrant issued by Judge John Cradlebaugh but there is little other information about his role in the massacre. In their list of actual and alleged participants in Appendix C of Massacre at Mountain Meadows, Walker, Turley and Leonard do not include Sims Matheny for lack of corroborating evidence.
Later Life
In 1859, Matheny married Ellen’s sister, Martha Jane Ray (1842-1890), also of Mississippi. Eventually they returned to Fillmore in central Utah. During the Black Hawk War, "Sims L. Mathens" was listed in the Millard County militia muster rolls and saw action in a ten-day campaign against Black Hawk’s raiders that included the engagement at Gravelly Ford in Sevier County, 1866.
The 1880 census lists, Matheny, age 46, in Fillmore with his wives Ellen (listed as suffering from a nervous debility) and Martha Jane and a servant. His wives were keeping house while Matheny and the servant were working on the railroad. Josiah Gibbs recollected that Sims and Martha raised an Indian boy named Manassa who reportedly assimilated into white society.
In 1881, Matheny died and was buried in Fillmore, survived by his two wives and children.
