I also have a Jennie Doty who died in MO., but she passed away in Joplin. One thing I would recommend to you. Contact the funeral homes in the town asking if they handled the services for your Jenny Doty Sparkman. If they did, ask them to please send you a copy of the Record of Funeral. Since she passed away in 1968, there should be some genealogical information in their record At least it might give you an idea of where to look, possibly in census. I've gotten parent's names and even places parents were born from the funeral records.
