Id hate to inform you but some of the information you have is wrong compared to what i have. If yours is right then that means we have the same ewing line but we so not. For one Thomas Ewing was born 1782 and died 1827. He married Margaret (Edwards) Ewing in 1805 in ross county ohio. Thomas father was John Ewing and he was born 1738 and died 1806 and his wife was Sarah Jenkins. Johns father was William Ewing born around 1696 and died around 1771 and married Jane Robertson. And Williams father was James Ewing born around 1665 and died 1740 and married Margaret Burley.
