and nephew
Charles James Fox Throughout Lady Sarah's association with the king and in its aftermath, her sister Caroline searched for a suitable marriage candidate. After the royal nuptials failed, Sarah's self-confidence was low and she worried about finding a good match as her three elder sisters had. By the end of the London season in 1761, the most suitable options – such as the
Duke of Marlborough – had moved on to others or been ruled out by her. A brief, secret engagement with
Lord Newbattle did not move forward. By the end of that year, another prospect named
Charles Bunbury emerged and began
courting her. Bunbury was a 22-year-old
Member of Parliament for
Suffolk and often attended political discussions at Holland House. He had not had a successful legislative career, but was considered handsome and witty – Sarah described him as a "Marquis in a French story book." Caroline made inquiries and found that he was the eldest son of a
baronet and came from a prominent family who owned lands in Cheshire and Suffolk. He was not deemed by her family to have a large enough fortune for them to live in fashionable society, but Caroline was ready for her matchmaking duties to be over, and the match was approved. Sarah, perhaps perceiving the familial and social pressure, consented to the union. The male adults in their lives – Sir William Bunbury, Henry Fox, and her brother, the
3rd Duke of Richmond – negotiated the marriage settlement. Sir William was prepared to settle an annuity of £2,000 as well as "a house in town and country" on the couple. Such a small settlement led Sarah's relatives to assume it must be a love match. They were wed on 2 June 1762 in Holland House's chapel. Upon their marriage, they went to live at
Barton Hall, Bunbury's country estate in Suffolk. He inherited
his father's baronetcy in 1764.
Separation and divorce The relationship was troubled nearly from the start. During their courtship, Sarah did not share her feelings and barely mentioned Bunbury in her letters, indicating a possible lack of enthusiasm. After the wedding, she viewed him as emotionally distant and quickly grew anxious for his affection. Bunbury's primary interest was
horse racing, which often kept him away. Lonely in their country home and lacking funds, Sarah filled her days with modest distractions such as gardening and visiting the bustling market town of
Bury St Edmunds, as well as seeking solace in her family. As a politician's wife, she was expected to host or attend local events and did so with enthusiasm. During one occasion, she reportedly secured 94 out of 100 votes while canvassing in the borough of
Morpeth. Sarah blamed herself for the failings of their marriage, which was also childless. Four years in, she grew tired of pretending it was successful and started behaving recklessly. She visited Paris, where her ostentatious flirting and gambling became the subject of gossip. She had relationships or affairs with several men, but the most prominent and long-lasting was with
Lord William Gordon, an Army officer and younger son of
Cosmo, 3rd Duke of Gordon. She gave birth to his illegitimate daughter, Louisa Bunbury, on 19 December 1768 and guiltily admitted the child's paternity to Bunbury. Seeking to avoid an embarrassing scandal, he agreed to raise Louisa but demanded that Sarah give up her lover. Sarah feared that leaving her husband would lead to her
involuntary commitment, a circumstance that was not uncommon among unfaithful or troublesome wives. Nevertheless, she and Lord William
eloped shortly afterwards to
Knole House, the country estate of a friend. Morally, she felt that she could not impose an illegitimate child upon her husband. Bunbury refused to take her back, and Sarah returned to her brother's house with her daughter. On 22 April 1769, her husband pursued a
judicial separation through
Doctors' Commons on the grounds of adultery: Lady Sarah Bunbury, being of loose and abandoned disposition, and, being wholly unmindful of her conjugal vow, &c. did contract and carry on a lewd and adulterous conversation with [...] Lord William Gordon, and they had frequently carnal knowledge of each other: the party proponent therefore prays right [...] that he may be pronounced to be divorced from bed, board, and mutual cohabitation with [...] Lady Sarah Bunbury, his wife. Bunbury's court filing, confirmed on 17 June 1769, invalidated his marriage agreement and served to protect his finances from any further children born to Sarah. Shortly after, she fled with Lord William to Scotland, staying there for half of the year to avoid public attention. Meanwhile, the affair was bringing dismay and disagreement to her family. Caroline found little fault in Bunbury's behaviour, placing the blame wholly on Sarah and her lover. Emily's husband accused Caroline of lax oversight and declared that the Duke of Richmond's will had been quite correct in placing his young daughters in their care. The family eventually persuaded Sarah to end the relationship, and so by December, she and her daughter were residing in a small manor house called Halnaker on the Lennox estate, Goodwood House. It was not
until 14 May 1776 that the decree of divorce was issued, as they were expensive, rare, and required a
private act of Parliament. The high cost stemmed from the necessity of filing three distinct lawsuits. While divorce was morally frowned upon, it had become more socially permissive in the 17th and 18th centuries as aristocratic men sought legal avenues to remarry and produce male heirs.
Press coverage and social exile Within days of the couple's separation, the affair grew into a great scandal. Gossip swiftly spread at court and elsewhere; after a visit to Kensington Palace, the writer
Lady Mary Coke came away with the news that "Lady Sarah ... had thrown off all regard to decency ... [her] story was all over the drawing room." Sarah's actions also gained widespread coverage in the British press. Aristocrats were prominent figures and their activities featured heavily in newspapers as production and readership increased during the 18th century. Stories of misconduct, which often combined fact and gossip, were a big driver of sales. Laden with guilt and self-loathing, Sarah did not pay the fee that would normally have suppressed such reporting. Sarah's notoriety was enhanced by her previous connection to the king and her royal ancestry, as well as the general British public's antipathy towards openly licentious aristocrats.
Town and Country, for instance, published a detailed description in April 1769 and declared "rank and beauty have been her ruin." While chastising Sarah as a "
Messalina", that publication also lent sympathy to her situation, noting her as an example of the type of wife to avoid but also how not to treat one after marriage.
The Morning Post, newly founded in 1772, quickly popularised scandal as entertainment; their reporting of the situation caused Sarah to complain that they were "full of lies and no news." When the finalisation of her divorce finally arrived in 1776, her sister Louisa was relieved that it coincided with the bigamy trial of
Elizabeth Chudleigh, which garnered much media attention and diverted some public interest off Sarah. In 18th-century Britain, a wife's public adultery typically meant the end of her social life. For twelve years, Sarah lived a self-described "solitary life" and was initially allowed to socialise only with family members; when other guests stayed at the Lennox estate, her brother ordered her to remain apart. Compared to her prior residences, Halnaker was small and outdated, so after seven years, he permitted the construction of a new home on his estate, called Molecomb House. Sarah possessed a deep interest in architecture – her family let her assist with the remodelling of
Frescati House, her sister Emily's house in Ireland – and she was now able to work on her own home's design. The historian Amy Boyington writes that the Molecomb project "provided her with a sense of purpose and usefulness during the long years of social obscurity" and enabled her to finally "live independently and respectably." Economy was still necessary, but it allowed her to live in style and comfort. The finalisation of her divorce also permitted her to revert to using her maiden name and provided her with opportunities to travel away from Goodwood House, such as to
Bath. ==Marriage to George Napier==
