Howe, when derived from the Old Norse: haugr, means hill, knoll, or mound and may refer to a tumulus, or barrow. Siward's Howe is named for Siward, Earl of Northumbria, the 11th-century Danish warrior. He was romanticised in the William Shakespeare play, Macbeth. Siward died at York during 1055 and is rumoured to have been buried beneath the tumuli at the wooded summit.[2][3]
