Armistead S. Nickens represented Lancaster County in the House of Delegates for two terms (1871–1875). Born into a free family, Nickens became prosperous enough by the end of the American Civil War (1861–1865) that the local agent of the Freedmen’s Bureau listed him as a respectable citizen capable of holding public office. The marker honors the county’s first and only elected Black representative in the House of Delegates.
