He never married and was succeeded by his third cousin, the eighth Earl. He was grandson of Rear-Admiral John Stanhope, son of Ferdinand Stanhope, younger son of the aforementioned Reverend Michael Stanhope. On his death in 1883 this line of the family also failed and he was succeeded by his fourth cousin Sir Henry Edwyn Chandos Scudamore-Stanhope, 3rd Baronet, of Stanwell, who became the ninth Earl (for earlier history of the baronetcy, see below). His eldest son, the tenth Earl, was a prominent Liberal politician and notably served as Captain of the Yeomen of the Guard from 1894 to 1895. On his death the titles passed to his younger brother, the eleventh Earl. He was a Captain in the Royal Navy. He died unmarried and was succeeded by his nephew, the twelfth Earl. He was the son of the Hon. Evelyn Theodore Scudamore-Stanhope, younger son of the ninth Earl. He had no sons and on his death in 1952 the baronetcy became extinct.
However, he was succeeded in the earldom and barony by his distant relative James Richard Stanhope, 7th Earl Stanhope, who became the thirteenth Earl of Chesterfield and thirteenth Baron Stanhope. However, he never petitioned for a writ of summons to the House of Lords in these titles and continued to be known as the Earl Stanhope. On his death in 1967 the earldoms of Stanhope and Chesterfield and barony of Stanhope became extinct. He was succeeded in the junior titles attached to the earldom of Stanhope – the viscountcy of Stanhope (of Mahon) and barony of Stanhope (of Elvaston) – by his kinsman, the eleventh Earl of Harrington.
The Stanhope Baronetcy, of Stanwell in the County of Middlesex, was created in the Baronetage of the United Kingdom in 1807 for Henry Stanhope. He was the grandson of Charles Stanhope, younger brother of the aforementioned the Reverend Michael Stanhope and grandson of the Hon. Arthur Stanhope, younger son of the first Earl of Chesterfield. His son, the second Baronet, assumed by Royal licence the additional surname of Scudamore in 1827. His son, the third Baronet, succeeded his fourth cousin as ninth Earl of Chesterfield in 1883.
