I searched over and over for an Agnes Harper in various records. I could not find her in any United States record before 1900. I tried numerous reasonable spelling variations on the first and last name. Then I located Agnes’ stone on FindAGrave.  The stone listed her name as Nancy Agnes Harper–not just Agnes. That was why I could not find her. Always consider the possibility that you have all the names a person used. That could be why you cannot find them.
