There is a Nathaniel Edwards that married Nancy Sprinkle in 1867, daughter of Harrison and Susannah Chappel, but the 1870 census lists the children by her previous husband, but the child William b. abt 1868 would be an Edwards I would think?. Are you looking for a child of this couple? or a child of Nathaniel's prior to his marrying Nancy? There is a David Edwards in the same location 1870, husband of Nancy - possibly his brother?
