I'm going to do a little work on this, though family members swear her name was not Ida Mary, but Ida May. (typos are easily made, not so easily caught and corrected) The dates and the region match, though Ida Paxton seemed to be a dominant name in the area during that time. I have a feeling I'm not going to find my Native American connection, it seems she signed off as "white" on just about everything. Maybe I'll get lucky.
Basically I am trying to prove the native American lineage in my children. I thought researching Ida would be the easy route. lol... joke's on me.
