She is also my ggg-grandmother too. I am beginning to believe she either died between 1860-70 or divorced Henry. Henry is listed in the 1870 census as a boarder without Amanda "manda" and the 1880 census has Henry as HH with a wife listed as "Mary". I am assuming he remarried. I also found a limited number of Messers in Perry County at that time and out of them a couple of them did not make it probable to be Amandas parents. The only one that sticks out was Stephen Messer. When I researched that, no one lists an Amanda as a known child. This is where my branch stopped. I am wanting to go to the Courthouse and get an original marriage certificate or locate a death record. Still looking for something to become available...ugh! Please keep me posted on your end. Sorry if I couldn't assist you at this point.
