Oǐ’vimána ( sing., Oǐ’vimán ), ‘scabby people’; oǐ’vǐ ‘scabby,’ mana ‘band,’ `people’ (Petter); according to another authority, ‘hive people.’ An offshoot of the Hévhaitä’nio . The name originated about 1840, when a band of the Hévhaitä’nio, under a chief known as Blue Horse, became infected from having used a mangy buffalo hide for a saddle blanket. They became later an important division. According to Grinnell (Social Organization, 1905) the name is also applied as a nickname to a part of the Northern Cheyenne on lower Tongue river, “because, it is said, Badger, a principal man among them, had a skin disease.”
