The Rock Presbyterian Church was organized in 1720. The first house of worship was in Chester Country, at what is now (1881) known as the "Stone Graveyard", in Lewisville, Elk Township; the second, erected by the "New Side" in 1741, at what is called "Sharp's Graveyard", at Fair Hill, Cecil County, Maryland; and the third in the present location in Cecil County, not far from the line of Chester County. The church was at its organization called "Elk River," and bore that and other names until about 1787, since when it has been called the "Rock." The church, having been originally located in Chester County, and since near the line, it has always had many members in this county. The "Stone Graveyard" contains a large number of graves.
