The information that I've accumulated says that Johnathan Alder (17 Sep 1773 - 30 Jan 1849) is buried at Foster Chapel Cemetery in Jefferson Township, Madison Co, OH. Mary Ann BLONT Alder (1785 - 1856) passed in Fulton, Whiteside Co, IL. I have Johnathan's parents as Bartholomew Alder (1733 - 1780) & Hannah Worthington Alder (~1745 - 1817). Hannah is buried in Foster Cemetery, Madison Co, OH.
