Ewing Young was an American fur trapper and trader from Tennessee who traveled in what was then the northern Mexico frontier territories of Santa Fe de Nuevo Mxico and Alta California before settling in the Oregon Country. Young traded along the Santa Fe Trail, followed parts of the Old Spanish Trail west, and established new trails. He later moved north to the Willamette Valley. As a prominent and wealthy citizen in Oregon, his death was the impetus for the assemblies that several years later established the Provisional Government of Oregon.
Ewing Young was born in Tennessee to a farming family in 1799. In the early 1820s he had moved to Missouri, then the far western edge of the American frontier, not far from the border of the Spanishcontrolled territories of presentday Texas, New Mexico and the Southwestern United States. While residing in Missouri he farmed briefly on the Missouri River at Charitan.
