Near this site lived six generations of the Chinn family, one of Prince William County's early
(black) families. The family traces its heritage to Nance, a slave born in 1794 on the Roe
Plantation near present day Lake Ridge. Nancy's daughter Mary Jane married Tom Chinn, a
fellow slave and they had eight sons. Following emancipation the Chinns bought 500 acres along
Telegraph and Davis Ford Roads. Several members of the family built homes in the area, known
as Agnewville, or later Chinntown. One son ran a general store; another donated land on which
the Mt. Olive Baptist Church stands. The family has a long history of service to the county.
Several members are buried in the church's cemetery.
