My BARNHART line extends back to Michael Barnhart, b. 8 May 1786, Columbia Co., PA. His son John B. Barnhart, b. 5 Oct 1817, PA, was my 3rd Great Grandfather. John B. Barnhart married Margaret Hart (b.1 Oct 1819, Ohio) on 22 Apr 1847, Seneca Co., OH. They lived in Adams Co., Indiana and Williams Co., Ohio. Any information about Michael BARNHART would be greatly appreciated. Jim Adams; jkadams@itis.com
