Thomas Pelham-Holles, duke of Newcastle-on-Tyne, was one of the major political figures under the first three Georges; his long career in the House, and in successive ministries, will be recounted in much more detail in the relevant succeeding volumes of this work.
Thomas Pelham, as he was until 1711, was the eldest son and namesake of Thomas Pelham, created Baron Pelham of Laughton in 1706, a prominent landowner based in Laughton in Sussex who sat in the Commons for the boroughs of East Grinstead and then Lewes from October 1678 to 1702. He was returned for the county itself in the first Parliament of Anne. Throughout, Pelham acted in Parliament as a moderate Whig, and from an early age the future duke of Newcastle was linked to a number of Whig families and individuals. In 1698 his half-sister Lady Elizabeth Pelham married the rising Whig politician Charles Townshend, 2nd Viscount Townshend, and for many years the younger Thomas Pelham saw himself as a follower of this brother-in-law.
At Pelham of Laughton’s death on 23 Feb. 1712 his heir, Thomas, still only 18 years of age, became 2nd Baron Pelham of Laughton and reportedly ‘the richest heir in England’.
Henrietta was also encouraged by her father’s will to marry her cousin Thomas to keep the estate and title together, despite the ongoing negotiations, set in motion after the will had been written but before Newcastle’s death, for a match between Henrietta and Edward Harley† (later 2nd earl of Oxford), the son of Robert Harley, earl of Oxford.
Thomas Pelham quickly added the name and arms of Holles to those of Pelham to signify his acceptance of this inheritance, but the dowager duchess of Newcastle was equally quick to contest the validity of the will of her late husband, angry at what she saw as his unwarranted parcelling out of the Cavendish lands she had brought to the marriage. She was aided in this by her ally, confidant and prospective kinsman, the earl of Oxford.
Oxford’s absence and lack of support led to a breach between him and the dowager duchess, who now also turned against the marriage of her daughter to Lord Harley. Lady Henrietta, still underage, took matters into her own hands, broke with her mother and looked to Oxford to act as her guardian. In early August 1713 he declared ‘that there is a necessity of the lady’s marrying somebody [and] that this must be done with speed as to her own affairs’. The urgency was caused in part by the proposal Pelham made to the late duke of Newcastle’s close friend and executor Henry Paget, 8th Baron Paget (later earl of Uxbridge), that, as the marriage between Henrietta and Harley was apparently off, he would willingly embark on negotiations for a match with her himself. Oxford hurriedly engineered the marriage of Lord Harley and Lady Henrietta, celebrated in private on 31 Aug. 1713, over the continuing opposition of the dowager duchess.
The dowager duchess rejected attempts at mediation, and, increasingly estranged even from her own daughter, continued to litigate. Almost all of the judicial decisions went against her whilst in the meantime the other parties set about trying to come to their own settlement.
This marked ‘a happy agreement for Lord Harley, and a plentiful provision there is for himself and his lady’, but Pelham did equally well.
Pelham came of age on 21 July 1714, only a few days after this agreement was formally signed, and marked his new status with a lavish feast in Sussex costing £2,000.
Pelham loudly proclaimed his adherence to the Hanoverian Succession and as a rich, young and ardent Whig he was quickly rewarded by the new king. In October 1714 he was created earl of Clare, a previous title of his benevolent uncle which had been extinguished at his death, and over the following months he received several offices.
On 2 Apr. 1717, after months of protracted negotiations, Newcastle married Lady Henrietta Godolphin, the daughter of Francis Godolphin, 2nd earl of Godolphin, and Henrietta, eldest daughter of John Churchill, duke of Marlborough (later suo jure duchess of Marlborough). Whereas previously Newcastle had been a loyal follower of his brother-in-law Townshend, in the early months of the ‘Whig Schism’ of 1717 he, with great prescience, threw in his lot with his new uncle (the husband of his wife’s maternal aunt) Charles Spencer, 3rd earl of Sunderland. It was almost certainly Sunderland who promoted his nephew at court, and on 13 Apr. 1717, only one day after Sunderland was himself made a secretary of state, Newcastle was appointed lord chamberlain of the household and three days later was sworn to the Privy Council. Thus began his public career in which he was involved at the heart of ‘old corps’ Whig politics and public life until his death in 1768.
