Earl of Bolingbroke
The title Earl of Bolingbroke has been created twice, once in the Peerage of England and once in the Jacobite Peerage.
Initial creation
The creation in the Peerage of England occurred on 28 December 1624, when Oliver St John, 4th Baron St John of Bletso, was created Earl of Bolingbroke. His eldest son and heir apparent, Oliver St John, was in 1641 summoned to the House of Lords through a writ of acceleration in his father's junior title of Baron St John of Bletsoe. However, he predeceased his father ; nevertheless, the writ of acceleration means that he is formally known as the fifth Baron St John of Bletsoe. The Earl was succeeded by his grandson, Oliver St John, 2nd Earl of Bolingbroke, who was the son of Sir Paulet St John, younger son of the first Earl. The 2nd Earl died childless in 1688 and was succeeded by his younger brother, Paulet St John, 3rd Earl of Bolingbroke, who represented Bedford in the House of Commons. He never married, and on his death, on 5 October 1711, the earldom became extinct.List of Earls of Bolingbroke (1st creation)
