Adam Francis Plummer Founder of Present Day Edmonston

Born into slavery to the powerful Calvert Family, literate and educated, Adam Francis Plummer rose to become the foreman for Charles Benedict Calvert (founder of the University of Maryland and member of Congress). Working on the nearby Riversdale plantation, he kept a diary of family life and attempted several escapes without success. At the close of the Civil War, Plummer and his wife Emily set out to reunite his family after several had been sold to the deep south during slavery.

In 1870 Plummer purchased 10 acres on the south end of the plantation (present-day Edmonston) to establish a settlement for his newly freed family. With an expertise in horticulture and a fondness for roses, he named the community Mt. Rose after the gardens established here.

A century later Adam Francis Plummer became a figure of major historical significance when his diary was found to be the only diary of any slave in U.S. history. The diary is now in the care of the Smithsonian.
