The grandson of a courtier, Stephen Poyntz, and son of a placeholder who was manager of the Prince of Wales’s staghounds,
In December 1806 Poyntz was invited to offer himself at the Sussex county by-election, sponsored by the Duke of Norfolk, but owing to his unwillingness to come to an arrangement with the Duke of Richmond (who disliked his politics) for the future of his seat, did not stand. His patron at St. Albans had hoped he would succeed so as to bring in his nephew Lord Duncannon, and in the event Poyntz gave up his seat to support the latter’s pretensions in April 1807. Duncannon failed to hold the seat. Poyntz again aspired to a seat for Sussex, but found he was not taken seriously there. ‘A great many people of different descriptions’ wanted him to stand at the St. Albans by-election of February 1809, but he ‘declined having anything to do with it’, nor would he consider it later, having found a ‘snug’ seat at Callington in April 1810, on the interest of his future son-in-law, Lord Clinton. On payment of his election expenses, he was guaranteed this seat for two years, even if his politics disagreed with the patron’s.
Poyntz appeared in the minority list on Ponsonby’s amendment to the Regency bill, 21 Jan. 1811. He informed his patron that he did not wish to oppose the reinstatement of the Duke of York as commander-in-chief of the army; but he voted for Morpeth’s motion on the state of Ireland, 4 Feb. 1812, for Grattan’s motion on Catholic relief, 24 Apr., and for Stuart Wortley’s motion for a stronger administration, 21 May. In August 1812 Lord Egremont described him as ‘an absolute slave of Lord Spencer and Lord Grenville’. In the next Parliament, apart from three votes for Catholic relief in 1813 and a vote for the censure of the Speaker on 22 Apr. 1814, no further votes of his appeared. Poyntz does not seem to have attended often in this Parliament. He was unable to vote with opposition on the Regent’s address, 25 May 1815, owing to a sudden illness. Lord John Townshend reported, 21 May, ‘He has written I believe to Lord Duncannon on the subject. He is even more vexed than I am because his politics not being so generally known as mine his opinions as to the war may be doubted.’ His interest in public life was much affected by a private tragedy in July 1815, when the overturning of a pleasure yacht cost the lives of his two sons and he himself narrowly escaped drowning, in full view of his wife. Lady Bessborough wrote: ‘I cannot bear to think of the poor Poyntz, and were it not that both have so strong a sense of the only consolation to human misery, religion, I could scarcely hope or wish them to survive such a misfortune’. In June 1817 Poyntz was described as ‘just the same odd, comical creature as ever’, and Countess Granville was told that ‘he gives little balls and waltzes himself at them’.
