Mary Ann Plummer Harris (1820 - c. 1923) settled along Broad Branch Road in the 1840s, and in the 1850s she bought a 2.3-acre farm on this spot. It was part of a small community of free Black landowners covering 6.2 acres. Mary Ann was a free woman who had grown up along the C&O Canal in a cottage belonging to her grandfather, Capt. George Pointer, who was born enslaved but bought his freedom at age 19. Harris's two-story frame house is pictured in the 1928 newspaper clipping below. Here she raised eight children, just blocks from the Belt Plantation where enslaved men and women toiled. She sent two sons to fight in the Civil War, and was a pillar of the community.

The Black families who had thrived here for more than 80 years scattered across the region. Oblivious to this history, a 1938 article in The Washington Post stated:
