Oakley Cabin African American Museum and Park is a 19th-century African American historic site.

The dwelling, inhabited until 1976, is now operated as a living history museum. Educators will find Oakley Cabin a valuable resource in teaching local and African American history. The Oakley Cabin African American Museum and Park provides hands-on living history experiences.

Oakley Cabin was originally part of the Oakley Farm, which occupied part of Colonel Richard Brooke’s large land tract known as “Addition to Brooke Grove.” Brooke was a Revolutionary War hero known as “the Fighting Quaker.” He built the “big house” called Oakley in 1764, which was destroyed in the 1970s.

Brooke, who died in 1788, willed all his property to his only child, Ann, who later married William Hammond Dorsey. They had five children. Like her father, Ann and William never lived on the Oakley Farm. Instead William built their home, Dumbarton Oaks, in Georgetown. When Ann died in 1802, William sold all of his Georgetown property and moved to Oakley. William died in 1818. The Dorseys’ son, Richard B. Dorsey, transformed Oakley into a farm, on which his 23 slaves worked.

Dr. William Bowie Margruder bought Oakley farm in 1836. A local doctor to both white and black families, Margruder owned 19 slaves to help farm the land. Prior to 1879, two more cabins were built on the property. Oakley Cabin is the only remaining one. After Dr. Margruder died in 1873, Josiah J. Hutton purchased the farm.

The 1½-story Oakley Cabin has a stone chimney with brick stack. Oak and chestnut logs are joined with dovetail joints and chinked with stones, now largely covered with cement. There are two rooms divided by a bead board partition wall. A boxed staircase leads to the upper loft.

According to census records from 1880 to 1920, between 22 to 37 people lived in the three cabins. The residents were both black and white, with jobs ranging from farm laborers and carpenters to blacksmiths and laundresses. The cabins formed a small roadside community that likely shared household tasks and sold produce and hand-made articles to travelers on the Brookeville Road. It represented a cross-section of cultures that make up the unique African American folk experience.

The Museum and Park

Oakley Cabin is a museum furnished to depict the various periods of its history and development. The ground floor room represents communal life at the cabin, centering around the open hearth. In the small adjoining room are displayed the 19th century tools and artifacts excavated in archeological digs at the cabin. Archaeologists are currently piecing together the evidence to try and date the construction of the cabin.

The oak and chestnut log cabin is a reflection of vernacular architecture and excellent craftsmanship through its dove-tailed notching and artful pegging. The rafters on the roof are “bird-mouthed” over the top log that serves as a plate. The floor of the first level sits on a double sill with a notch in the foundation to allow two logs – one for the floor and one for the wall.

The cabin sits on a 2-acre tract that is part of a larger park running along Reddy Branch. The mill pond for Newlin’s Mill was located in the low area behind the cabin. A trail, partially laid inside the old millrace, leads from the cabin to the site of the mill at the intersection of Brookeville Road and Georgia Avenue. Numerous wild plants can be seen, many of which are edible or medicinal and were used by local people. Hawks, foxes, deer, raccoons and other wildlife can often be seen from the cabin or trail. The trail also passes stone quarries used to dig local stone.
