Thank you for your suggestions. Actually, I have the Nye & Cole families researched- it is the Hart family I am having trouble with. I cannot find a connection between Margaret Jane Hart, and any of the Hart families in the area at that time. The information for the marriage of James N. Cole and Margaret J. Hart, as well as 1870 & 1880 census, has them in Auburn Twp., Crawford Co., Ohio. I cannot find a Hart familiy that connects to Margaret J.
