The cornerstone for the [[Darnestown Presbyterian Church]] was laid on September 14, 1856 by a congregation organized in 1855. John L. DuFief, a community leader and owner of the DuFief Mill, donated {{convert|3|acres}} of land for the church. The completed structure was dedicated on May 22, 1858.<ref name="Kelly218">{{harvnb|Kelly|Maryland-National Capital Park and Planning Commission|2011|p=218}}</ref> The building was expanded in the late 1890s, and a bell tower was added at that time.
