SETH CARHART

I am searching for information about Seth Carhart and his parents and siblings. Seth CARHART died in Muskingum Co.
Ohio in 1806 leaving a large family of children who married and lived in the Muskingum/Coshocton Co area of Ohio.

Seth Carhart was an educated man who was involved in the legal profession. He came to Muskingum, Co, OH about 1796 from the Morgantown area of Monongalia Co, WV with the James Johnston family.
I have traced Seth Carhart back to an association with James Johnston in 1789 in Monongalia Co, WV and feel there may be a family relationship.
I would appreciate any information about Seth Carhart.

Thank you, Lillian Densley
