Looking for Francis Frankie Jane Harrell and Daughter Mary Jane Harrel Information

My great, great grandmother was Francis Jane Harrell, also known as Frankie or just grandma Harrell. Last known place that she recided was in Hartford, Arkansas. Her daughter which was Mary Jane Harrell and was my great grandmother married Claude Bolden Camp. They had a son (my grandfather) James Alexander Camp. (He later changed Camp to Kemp). Mary Jane was put in a state hospital in Little Rock Arkansas as a young woman and died there of a brain disease. Great, great grandmother raised my grandfather in Hartford, Arkansas. She lived on KT Hill there. I have not been able to find out any other information on where they are buried. Mary or Frankie. Mary was a full blooded Cherokee. If anyone has any information I would so appreciate it. you can contact me at conniejson@aol.com

I am not sure what Francis Jane Harrel's maiden name was or if Harrel is her maiden name. I just do not have enough information. But would love to find out some kind of heritage. Thanks so much.
