English: The Italianate rowhouse located at 736 Jackson Place on Lafayette Square in Washington, D.C., was built in 1870 for Cornelia Knower Marcy, the widow of politician William L. Marcy. A renovation and expansion completed in 1895 was designed by Carrère and Hastings. The building is often called the Marcy-Townsend House and is a contributing property to the Lafayette Square Historic District. Previous occupants include Representative John Stoughton Newberry, Secretary James G. Blaine, Representative William Lawrence Scott, businessman Richard H. Townsend (see Townsend House), its most notable occupant, President Theodore Roosevelt, who briefly lived there in 1902 when the White House was under renovation, Dutch Ambassador Willem Louis Frederik Christiaan van Rappard, the Women's City Club of Washington, and the National Lutheran Council of the United Lutheran Church of America. The building houses offices of the United States Digital Service.
