You do know the Osage, Comanche and others arise out of the same Assinoboine group as the Oglala.
But my cousins were Muscogee..and Bodéwadmi...and I am Bodéwadmi also.....or Anishinaabe as they called themselves.
I happen to live on a Rez....that is not my own. But in Oklahoma, yes.
Osage and Oglala are related to Assinobione.
Comanche is variant of Shoshone, a Uto-Aztecan language. Completely different from the Siouan language family.
