Mary Anne Thompson was born in London on 3 April 1776, the daughter of a tradesman. Before she was 18 she married a stonemason called Clarke. Shortly after they married he became bankrupt and she left him, but was pregnant and gave birth to Ellen. Ellen went on to marry Louis -Mathurin Busson du Maurier. They had a son George du Maurier (1834 – 1896) the famous caricaturist, and Mary went on to become the great-grandmother of the famous novelist Daphne du Maurier, who wrote a book about Mary Anne Clarke.

Mary was both attractive and intelligent, and by 1803 she had become involved in the courtesan world where she became a kept woman by wealthy men, and it was while in this society she attracted the attention of Prince Frederick, Duke of York, the second child of George III. He was Commander in Chief of the army and brother to the Prince Regent. He was the famous Duke of York immortalised in the nursery rhyme about marching his men up to the top of the hill and then down again, which was really mocking his ineffectiveness at being the Commander in Chief of the army.

Mary became his mistress and he set her up in a fashionable house, but could not meet the upkeep or their lavish lifestyle, which he was subsidising from his Civil List income. They parted in 1805 and he bought her silence with a payment of £10,000 and annual pension of £400. He subsequently cancelled this in 1808 and she sought revenge! Rumours were abounding at this time of the corrupt practice of the sale of commissions in the army and this was finally given credence by a Major Dennis Hogan who alleged he had been passed over for promotion because he would not meet Mrs Clarke’s financial demands. The case was taken up in parliament by Colonel Gwyyllm Wardle, MP for Okehampton, and it led to the resignation of the Duke of York. There was much mockery in society of this episode, and many cartoons - one of which is in the museum. He however was later reinstated. Colonel Wardle became a popular hero in the move against corruption.

Mary, who was angry that he had exposed her in parliament, then schemed to get an upholsterer called Francis Wright to sue Wardle for a non-payment of a bill of furniture for her new London home. He was found guilty and ordered to pay £1,095 for the furniture and £1,194 in legal costs. He vowed revenge on what he saw as a conspiracy. In 1809 he brought a case against them but he lost and faded from public life, leaving parliament in 1812 in severe financial trouble. He then fled abroad and died in Florence in 1833.

In 1804 Mary had moved to Exmouth and lived at Manchester House, now Chester House which the duke discreetly visited, and there is a blue plaque there to see. When she left Exmouth she lived in Loughton, Essex and in 1811 she commissioned an Irish sculptor Lawrence Gahagan to do a marble bust of herself which portrayed her as rising from the petals of a sunflower. It stood in her house between portraits of The Duke of York and Colonel Wardle. The bust is now in Room 17 of the National Portrait Gallery in London, who bought it in 1965. The room is called Royalty, Celebrity and Scandal! In 1813 she was prosecuted for libel and imprisoned for nine months. On her release she went to live in France and died in Boulogne-sur-Mar on 21 June 1852, aged 76. So ended an adventurous life of which Exmouth played a part!
