Earl of Grantham is a title in the Peerage of England created on 24 December 1698, along with the titles Viscount Boston, of Boston in the County of Lincoln, and Baron Alford, of Alford in the County of Lincoln, for Henry de Nassau d'Auverquerque, a British Army officer and cousin of King William III of England. The titles were created with a special remainder, failing heirs male of his body, to his three brothers Cornelius, Maurice, and Francis, in like manner respectively.[1] Since both his sons and as well his three brothers had predeceased him, the titles became extinct upon his death in 1754.
