Sarah here are my notes for Mary Shrum: Rockingham County court house records show that on 28 July 1788, Mary Shrum, orphan of David, was bound over to Christian Dedimore by overseers of the poor. Mary had been born 10 years earlier, on 15 February 1778.On 19 December 1796 Mary Shrum was married to Jacob Yankey by John Welch.Marriage bonds were posted by Jacob Yankey and Christian Dedimore. Jacob and Mary Yankey later moved to Kentucky. They are found in Mercer County, Kentucky, on the 1850 federal census under the surname "Younker", living with their son, Andrew. John Shrum's note of 4 February 2010:Information from Phillip L. Baker on 3 February 2010 indicated that the Perryville Battlefield State Park site (on line) has information about the family home in Kentucky.I found information at the site on the battle, and the area around the battlefield.I did not find information about the Yankey family or home at the battlefield site.
Regarding the marker for Anna Maria and Jacob Schramm: In recent times a marker was placed in the Prospect Hill Cemetery in York, Pennsylvania, for Jacob and Anna Maria Schramm. This is not their confirmed burial site, but a possible one. The marker was placed by a descendant,Lillian McNutt [deceased 1995], of Houston, Texas.
