1850 Muskingum Co Ohio lists an Alexander McClury, which I have found to be McClurg. He has the three names for sons, David, Robert and Leander and also he has a son James McClurg whom I traced on over to Darke Co Ohio.Alexander's wife is Isabil. Alex b. Ohio and Isabil VA.Some of the children b. in VA some in Ohio. Probably the panhandle around Jefferson Co.Ohio.Maybe this will give you a clue of where to search.
