To be a successful political hostess in the 18th-century, one needed to combine the social with the political. Energetic and able to find humour in her role, Susanna attained political influence from her social interactions at court and by entertaining in her home. Their household was especially political. Her husband, a
Whig, was a powerful figure who held many high offices including
Lord Privy Seal and
Lord President of the Council. While not ambitious or particularly adept, his amiability helped him advance and she aided his career by steadfastly nurturing his political aspirations and by making requests of politicians who stayed at their home. Part of her influence was their connection with the prime minister
William Pitt the Younger; the Staffords were strong supporters and often hosted him. By 1788, Lady Stafford (as she was now known) was recognized as one of the most influential women in British politics. Susanna was close with her children and took an active role in their education, encouraging their attempts at self-improvement. She doted on her handsome son
Granville, who was both the youngest and the favourite of their large family. From an early age she regularly raised subjects of ethical and political significance with him, and encouraged him to enter politics. In one letter sent in 1789, she wrote that she wished for him "in
all his Studies to equal any of the young Men and to excel [at] most of them". The family, including Granville, regularly hosted distinguished dignitaries such as William Pitt where scholarly dinnertime conversation was common. Lady Stafford, like many of her time, was a religious person and felt public – rather than private – displays of worship was important to set a positive example for others. A woman of strict morals, she warned her son of the dangers of having relationships with married women, but failed to prevent his affair with the
Countess of Bessborough; instead, she encouraged him to pursue a respectable marriage, which he did a few years after her death by marrying
Lady Harriet Cavendish. She also discouraged his gambling. In 1793 Susanna's niece,
Lady Augusta Murray, scandalously married King George's younger son
Prince Augustus Frederick, Duke of Sussex, an event that caused great embarrassment for Susanna, as the two women had had a close relationship and the union was not allowed due to the
Royal Marriages Act of 1772. Susanna apologised to the outraged king by writing that she had no "knowledge of this lamentable affair," and withdrew her political support from Augusta's father, Lord Dunmore. By 1794, Lord Stafford was seventy-three and ready to retire, despite Susanna's attempts to dissuade him. Her involvement in politics effectively came to an end, leaving her feeling "glum". Her final years were spent with her increasingly large family and caring for Lord Stafford as he lost his eyesight. He died on 26 October 1803 at Trentham Hall, aged 82. He left her £10,000 in his will. She died at her residence in
Mayfair on 15 August 1805 and ten days later was interred at
Trentham Hall, Staffordshire. Her son's two illegitimate children –
Harriet and George – were given her maiden name, Stewart. A collection of her letters, mainly to her daughter Charlotte, was purchased by the
University of Birmingham in 1984. Their content, which "reflect[s] the social life of women in late 18th century high society", covers a variety of topics including politics, parenting, and religion. ==Gallery==
