No original buildings survive from Edmondson's Reserve, a tract first used as a private Indian Reservation and later as farmland worked by enslaved African Americans and White tenant farmers, now part of the 4-H Park of Caroline County. The Doncaster Dwelling, built in 1829 on the 800-acre tract called Doncaster one mile east of Edmondson's Reserve, was relocated here to serve as an interpretive center and to represent the one-room dwelling occupied by Peter Still's mother on the day in 1806 that Peter and his brother were sold South by the owner of Edmondson's Reserve. It was chosen because it corresponds exactly with the cottage Peter described in his 1856 slave narrative, The Kidnapped and the Ransomed, because it is a strong example of the one-room dwellings common from the earliest European settlement through the mid-1800s and housing roughly 85% of local residents in the early 19th century, and because architectural and land-record research indicates that it and his mother's frame cottage had a similar sequence of residents: enslaved African Americans, then White tenant farmers, and finally independent farmers.
