Lord John Grey's son
Sir Henry Grey was in 1603 raised to the Peerage of England as
Baron Grey of Groby,
in the County of Leicester. He was succeeded by
his grandson, the second Baron, who was created
Earl of Stamford in the Peerage of England in 1628. Lord Stamford later fought as a Parliamentarian in the
Civil War. His eldest son
Thomas Grey, Lord Grey of Groby, was a leading Parliamentarian in the Civil War. Stamford was one of the judges at the trial of
Charles I and one of the
regicides who signed the King's death warrant. He predeceased his father and never succeeded to the earldom. Lord Stamford's daughter Lady Elizabeth Grey married
George Booth, 1st Baron Delamer, and was the mother of
Henry Booth, 1st Earl of Warrington. Stamford was succeeded by his grandson
Thomas, the second Earl and the only son of Lord Grey of Groby. Thomas Grey was a politician and served as
Chancellor of the Duchy of Lancaster and as
President of the Board of Trade. He was childless and on his death in 1720 the titles passed to his first cousin
Harry, the third Earl. He was the son of the Hon.
John Grey, younger son of the first Earl. He was succeeded by his son, the fourth Earl. He briefly represented
Leicestershire in the
House of Commons. Lord Stamford married his second cousin once removed
Lady Mary Booth, daughter of
George Booth, 2nd Earl of Warrington (on whose death in 1758 the earldom of Warrington became extinct). When
Harry Grey, 4th Earl of Stamford died the titles passed to his son,
George Grey, the fifth Earl; he sat as Member of Parliament for
Staffordshire and served as
Lord-Lieutenant of Cheshire. In 1796 the barony of Delamer (which became extinct in 1770) and earldom of Warrington held by his mother's family was revived by his creation as
Baron Delamer and
Earl of Warrington in the
Peerage of Great Britain - he refused the offer of a marquessate, so as to become known as the Earl of Stamford and Warrington in recognition of the great estates he had inherited from the
Booth family. He was succeeded by his son,
George Grey, the sixth Earl. He represented
Aldborough and
St Germans in Parliament and was Lord-Lieutenant of Cheshire. His son styled Lord Grey of Groby (1802–1835), was summoned to the
House of Lords by a
writ of acceleration in his father's
subsidiary title of Baron Grey of Groby in 1833; he, however, predeceased his father. Lord Stamford was therefore succeeded by his grandson,
George Grey, the seventh Earl. He was the son of Lord Grey of Groby and had already succeeded as ninth Baron Grey of Groby on his father's death. Lord Stamford was a great patron of the
Turf. On his death in 1883, the barony of Delamer and earldom of Warrington became extinct (although his wife remained
Countess of Stamford and Warrington until her death in 1905). The seventh Earl was succeeded in the barony of Grey of Groby and the earldom of Stamford by his third cousin once removed the Reverend
Harry Grey, as eighth Earl. He was the son of the Reverend Harry Grey, son of the Hon. John Grey, third son of the fourth Earl. He lived in South Africa, and had married his housekeeper
Martha Solomons after she had already given birth to two of his children, the elder of whom was a boy. As this son was born before the date of his father's marriage, his illegitimacy prevented his inheriting the title; while a third child, born after the marriage and therefore legitimate, could not inherit the earldom because she was female. More information on this episode can be found in
Enthusiasms, essays by the historian
Mark Girouard. The eighth Earl was succeeded by his nephew,
William Grey, the ninth Earl. However, it was not until 1892 that the Committee for Privileges of the House of Lords confirmed the latter in the title, as the Committee wished to be assured that the marriage contracted by the eighth Earl while he lived abroad had not produced a legitimate heir. On the ninth Earl's death the titles passed to his son,
Roger Grey, the tenth Earl. He served briefly as
Parliamentary Private Secretary (unpaid) to the
Secretary of State for India,
Lord Peel, in 1922 and was also
Mayor of
Altrincham from 1937 to 1938. Lord Stamford never married and on his death in 1976 his family titles became extinct. ==Estates==
