Philip Herbert, 7th Earl of Pembroke

Philip Herbert, 7th Earl of Pembroke, 4th Earl of Montgomery KB (1652/53 – 29 August 1683) was an English nobleman and politician who succeeded to the titles and estates of two earldoms on 8 July 1674 on the death of his brother William Herbert, 6th Earl of Pembroke. A convicted murderer, he has been called "the infamous Earl of Pembroke." Although the murder of Sir Edmund Berry Godfrey, which sparked the Popish Plot, has never been solved, a strong body of opinion points to Pembroke as the killer.

Baptised on 5 January 1652/53 and brought up in Wiltshire at Wilton House, Pembroke was the son of Philip Herbert, 5th Earl of Pembroke, being the eldest son of his father's second marriage to Katherine Villiers, a daughter of Sir William Villiers and his wife Rebecca Roper. His paternal grandmother was the 4th Earl's first wife; his step-grandmother was Anne Clifford, daughter of George Clifford, 3rd Earl of Cumberland, and widow of Richard Sackville, 3rd Earl of Dorset. He was created a Knight of the Bath at the coronation of King Charles II.

As he grew up, Herbert was soon seen as a throwback to his grandfather Philip Herbert, 4th Earl of Pembroke, although of an even more violent character.

On 8 July 1674, at the age of twenty-two, Herbert succeeded his elder half-brother William as Earl of Pembroke and Earl of Montgomery, and on 17 December the same year he married Henrietta de Kéroualle, the sister of Charles II's mistress Louise de Kéroualle. By this marriage, Herbert had his only child, a daughter named Charlotte, who married firstly John Jeffreys, 2nd Baron Jeffreys, (son of the notorious hanging judge), and secondly, Thomas Windsor, 1st Viscount Windsor.
