I think this was my great-grandmother, Anna (Cameron) Johnston Cameron, who sold the property, but am not sure.  If she and/or John purchased property in Arenac County, Michigan (where they were living when John died) during the same approximate time frame (January 1892), that might bolster the case for identifying Anna and John Johnston as the sellers.  Their daughter, Isabelle Johnston, was born in Roscommon County in July 1890; daughter Blanche was born in Arenac County in July 1895.  In addition, I'd like to see the deed where they purchased (or inherited) the property.  Need another look at the deed to get the exact description.
