Yup. Ottowae/Wyandotte descendant here. When I was young I used to hear my grandmother mention “Indian school”. Always in passing and never elaborated on. As a child it was something I never thought much of. There’s all sorts of schools out there. Religious and otherwise. I assumed it reference schools run by or on the reservations. Heh, nope. She passed long before I understood or ever thought to ask unfortunately.
