We corresponded a few years ago regarding this line. I am confused about David Clark Acheson and Mary Cherry Acheson. My info shows that David Clark Acheson died in 1854 in Muskingum Co, and Mary Cherry Acheson died in 1850 in Muskingum Co. Therefore, it would be a different family on the 1860 census in Iowa. I know the rest of the info matches, but what did you find out? Was Mary Jane Acheson actually Jane Acheson Van Horn? Did David Clark and Mary Cherry Acheson actually relocate to Iowa?
