OMAHAS, a tribe of North American Indians of Siouan stock. They were found on St Peter’s river, Minnesota, where they lived an agricultural life. Owing to a severe epidemic of smallpox they abandoned their village, and wandered westward to the Niobrara river in Nebraska. After a succession of treaties and removals they are now located on a reservation in eastern Nebraska, and number some 1200.
