Pat,
Graceham Cemetery is across the street from Graceham Moravian Church. Graceham is about 2 miles east of Thurmont Maryland, off State Route 15 in Frederick County Maryland. Thurmont is roughly 20 miles south of Gettysburg Pennsylvania. It is about an hour west of Baltimore Maryland. I'm sure Harry knows of Frederick as it is a historic city. Francis Scott Key, who wrote the US's national anthem, lived there as did Roger B. Tawney who was the US Supreme Court's Chief Justice prior to the Civil War. Some of my ancestors helped settle Frederick County and start the Moravian Church at Graceham. I, though, am actually from New Jersey. If you want more specific directions to Graceham, let me know.
