Lord Crawford died on 11 August 1781 at Crawford Lodge, Fife, Scotland. He was succeeded in his titles by his son, George. Upon his son's death in 1808 with no heir, the male line of the 17th Earl of Crawford and 1st Earl of Lindsay became extinct, and his titles passed to the male heirs of the 9th Earl of Crawford, under the regrant of 1642. His widow, the dowager Countess of Crawford, outlived George and both of their children before her death on 6 October 1809.^[5]
