RobertaKM on Family Tree Circles

It is my understanding that my dad's mother was decended from a native american tribe but noone knows which one. Her name was Odelie Campeaux (Campeau) I am not sure where she was born between 1901-1904. She was a school teacher in Lebanon, OR. She married Clem Speasl and had three children: Larrey, Cheryl and Eugene. She lived in Lebanon, OR and died Dec. 1980. She had a brother named Kenny and I think a sister named Nell but that is everything I know about her side of the family. However I would like to know more. I will be thankful to anyone who can stear me in the right direction.

My Dad was Larrey Joesph Speasl. I am seeking any and all information about his mothers side of the family.
