Romancoke is an unincorporated community in King William County, Virginia, United States.

Eventually, in the early 19th century, George Washington Parke Custis, father of Mary Anna Randolph Custis Lee (wife of Gen. Robert E. Lee) inherited Romancoke Plantation, as well as Arlington and White House Plantations.

His will appointed Gen. Lee as executor, and directed him to manumit approximately 200 slaves within five years of his death (which happened in 1857).

The American Civil War and Emancipation Proclamation intervened, but Gen. Lee fulfilled the clause by December, 1862.

[3] His youngest son, Robert E. Lee, Jr., inherited Romancoke and after the war took up residence (about four miles from West Point).
