The Pelhams, one of the most prominent families in East Sussex, were descended from the illegitimate son of John Pelham, who first represented the county in 1399 and rose to become treasurer under Henry IV.
Pelham entered Parliament for East Grinstead in 1621. His paternal grandmother had been the aunt of Thomas Sackville†, 1st earl of Dorset, and it is possible that his father persuaded the 3rd earl, the dominant electoral patron in the borough, to nominate Pelham in exchange for supporting for Dorset’s steward, Richard Amherst*, at Lewes.
Pelham’s estate, concentrated largely in the Pevensey and Hastings rapes of east Sussex, was sufficiently large for him to be deemed capable of lending £100 towards the Privy Seal loan of late 1625, although his assessment was reduced to £60 the following March.
Pelham played a vital role in the administration of East Sussex in the 1630s.
Despite increasing ill health, he was returned for the county at both elections in 1640. A moderate supporter of Parliament in the Civil War, he withdrew from county administration after the king’s death. He was, nevertheless, elected to the first Protectorate Parliament, together with his eldest son, John, but died before it met, and was buried at Laughton on 28 Aug. 1654. Despite three happy marriages and a wide circle of friends and interests, he complained in his will that he had experienced ‘nothing but vanity and vexation, and for minutes of peace and prosperity enjoyed have had months of troubles and disquietude’. He asked to be buried ‘without pomp, feast or heralds, having observed the abuse of them at such times’. His eldest son, John Pelham, had already sat for Hastings in the Long Parliament and represented the county in nine parliaments between 1654 and 1698.
