In many ways, the story of Prince George’s County’s Ridgley Community is the story of America’s post-slavery experience. The Arthur and Mary E. Ridgley House, located on Central Avenue in Landover, Md., houses documents and mementos relating to the county’s historic Ridgley family and the emancipated Americans whose influence allowed them to develop farming land, build a church, barter for a school and stimulate economic growth.

The community thrived for over 140 years throughout the 18th and 19th centuries and now, Mildred Ridgley Gray, founder and CEO of the Mildred Ridgley Gray Charitable Trust, hosts an open house to share the community’s historical impact in Prince George’s County.

The Mildred Ridgley-Gray Charitable Trust was established 2001 to raise public awareness of the Ridgley (also known as Ridgeley or Ridgely) legacy. The organization also aims to maintain the Arthur and Mary Ridgley House, support the preservation of the Historic Ridgely United Methodist Church and Cemetery and the Historic Ridgeley School, among other things.

The open house is scheduled for Sept. 25, from 10 a.m. to 2 p.m., at the Arthur and Mary Ridgley House located at 8118 Central Ave., Landover, Md. For more information, call 410-435-0647.
