“Oh Shenandoah” (also called simply “Shenandoah” or “Across the Wide Missouri”) is a traditional American folk song of uncertain origin, dating to the early 19th century.
The song appears to have originated with Canadian and US voyageurs or fur traders traveling down the Missouri River in canoes, and has developed several different sets of lyrics. Some lyrics refer to the Oneida chief Shenandoah and a canoe-going trader who wants to marry his daughter. By the mid 1800s versions of the song had become a sea shanty heard or sung by sailors in various parts of the world Until the 19th century only adventurers who sought their fortunes as trappers and traders of beaver fur ventured as far west as the Missouri River. Most of these Canadian and US “voyageurs” in the fur trade era were loners who became friendly with, and sometimes married, Native Americans. Some lyrics of this song heard by and before 1860 tell the story of a trader who fell in love with the daughter of the Oneida Iroquois chief Shenandoah (1710–1816), who lived in the central New York state town of Oneida Castle. He was a co-founder of the Oneida Academy, which became Hamilton College in Clinton, New York, and is buried on the campus grounds
