John Bell

There were so many people with the name John Bell it can be confusing.  My John Bell was born sometime in the 1700's in either NC or SC. He was married to Mary Green when she was 16 years old.  Mary was born about 1780, daughter of Peter Green and Thamara? in old 96 district SC.  John was the son of John Bell and Sarah?.  When he and Mary Green married they went to Tennessee (dont know where in Tennessee) and there was where my gr.gr. grandmother Mary Bell was born (She later married James Boatright).   The family later moved to Coweta county, Ga..  John Bell must have died there because about 1855, Mary Green Bell went to live with her Daughter Mary and son-in-law James Boatright in Carroll county, Ga.  Mary is buried in the old Jordan cemetary in Carroll county, Ga.  She died in 1882.  Would love to find the ancestry of this John Bell.
