Lady Mary Fox was born Mary FitzClarence, the fourth of the ten children and the second of the five daughters of the future King William IV of the United Kingdom and his mistress Dorothea Jordan, on December 19, 1798, at Bushy House in the London Borough of Richmond upon Thames. Mary’s paternal grandparents were King George III of the United Kingdom and Charlotte of Mecklenburg-Strelitz. Francis Bland, a stagehand, and his mistress Grace Phillips, an actress were her maternal grandparents.

From 1790 until 1811, before he became king, King William IV of the United Kingdom had a long-term relationship with actress Dorothea Jordan. Their relationship resulted in ten children who were given the surname FitzClarence. The surname comes from the Anglo-Norman Fitz, meaning “son of” and Clarence, from King William IV’s title before he became king, Duke of Clarence.

Dorothea Jordan was born Dorothea Bland was born in County Waterford, Ireland, the daughter of Francis Bland, a stagehand, and his mistress Grace Phillips, an actress. Her mother encouraged Dorothea to enter the theater, and within a few years, she began to draw large crowds for her performances. She left Ireland in 1782 and moved to Leeds, England. It was at this point that she took the name Jordan. She performed for three years with the York Company, before being lured away in 1785 to move to the Royal Theatre, Drury Lane in London. By then, Dorothea was becoming a very popular performer and could be counted on to bring large crowds every night. It was at Drury Lane that her life would come to the attention of The Duke of Clarence several years later.

In 1790, Dorothea was first noticed by The Duke of Clarence (later King William IV) while performing at Drury Lane. They quickly began an affair that would last for the next 21 years. Dorothea moved in with the Duke at his home, Clarence Lodge in Roehampton, London, England and later they moved to Bushy House in Bushy Park in Richmond upon Thames, London, England.

In 1797, King George III of the United Kingdom appointed his third son William, then Duke of Clarence, the ranger of Bushy Park. The position came with the residence Bushy House in Bushy Park. William and Dorothea lived there with their ten children until their relationship ended in 1811. William continued living there with his children and later with his wife Adelaide Saxe-Meinigen after they married in 1818.

The children of King William IV and Dorothea Jordan had an elder half-brother, William Henry Courtney, born around 1788 to an unknown mother, and named after his father whose given names were William Henry. Dorothea Jordan cared for William, and she was fond of him and he was fond of her. William served in the Royal Navy from 1803 until 1807 when his ship HMS Blenheim was lost in a gale off Madagascar. Despite an extensive search, no trace of the ship was ever found. 590 men were lost aboard HMS Blenheim, including King William IV’s eldest illegitimate son nineteen-year-old William Henry Courtney.

Nine of the ten children of King William IV and Dorothea Jordan were named after nine of William’s fourteen siblings. The tenth child was given William’s middle name Henry.

• George FitzClarence, 1st Earl of Munster (1794 – 1842), married Mary Wyndham, had seven children

William and Dorothea’s children married into the British aristocracy and their many descendants include a number of notable people including sisters Princess Alexandra, Duchess of Fife and Princess Maud, Countess of Southesk (granddaughters of King Edward VII and daughters of Princess Louise, Princess Royal and Alexander Duff, 1st Duke of Fife, a descendant of Dorothea Jordan and King William IV), Duff Cooper, 1st Viscount Norwich (British diplomat, Cabinet member, author), John Crichton-Stuart, 7th Marquess of Bute (also known as Johnny Dumfries, racing driver), and David Cameron, Prime Minister of the United Kingdom.

By 1811, William was pressured by his family to find a suitable wife. At the time he was fourth in line for the throne following his elder brother The Prince of Wales, the future King George IV, George’s only child Princess Charlotte of Wales, and George’s next oldest brother who was childless Prince Frederick, Duke of York. William gave in to the pressure and ended his relationship with Dorothea but ensured she was well provided for. William became closer to the throne when his niece Princess Charlotte died in 1817 giving birth to a stillborn son. When King George IV died in 1830, William succeeded to the throne. Although William had ten children with Dorothea Jordan, his marriage with Adelaide of Saxe-Meiningen produced no surviving children. King William IV was succeeded by his niece Queen Victoria. Queen Victoria had relationships with her first cousins, King William IV’s illegitimate children. They are mentioned in Queen Victoria’s diaries when visiting Windsor Castle.

Mary and her siblings had little contact with their mother Dorothea Jordan after 1811 when their father ended his relationship with her. After losing much of her savings when her daughter Augusta and her husband ran up large debts in her name, Dorothea’s health quickly began to decline. Virtually penniless, Dorothea Jordan died in Saint-Cloud, France on July 5, 1816, at the age of 54. She is buried in the local cemetery in Saint-Cloud.

Like her eldest brother George, Mary also married another illegitimate child. Charles Fox was the illegitimate son of Henry Fox, 3rd Baron Holland, through an affair with Elizabeth Vassall, the wife of Sir Godfrey Webster, 4th Baronet. Charles’ mother Elizabeth was divorced by her husband on the grounds of adultery and two days later, she married Charles’ father. After their marriage, they had four more children, Charles’ siblings. On June 19, 1824, at the Parish Church of St. George in Hanover Square, Mayfair, London, England, Mary married Charles Fox but their marriage was childless. Mary and Charles established their household in Little Holland House, a Fox family property in Kensington, London, England.

In 1835, Mary was appointed State Housekeeper at Windsor Castle. Two years later, Mary’s father King William IV died and Mary’s first cousin Victoria ascended the throne. Like her siblings and their spouses, Mary and Charles occasionally dined at Windsor Castle with Queen Victoria. In 1837, Mary published a utopian feminist gothic novel entitled “An Account of an Expedition to the Interior of New Holland”. New Holland was a contemporary European name for Australia. In her novel, Mary portrayed New Holland as “a mysterious and unreal” place.

Mary’s husband Charles Fox had a brief career in the Royal Navy and a long career in the British Army. In 1809, when he was thirteen, Charles joined the Royal Navy and served as a midshipman until 1813, participating in the Napoleonic Wars. Dissatisfied with his prospects, in 1815 he joined the British Army and served in the 85th Regiment of Foot. Charles was rapidly promoted to Lieutenant in 1818, Captain in 1824, Major in 1825, and Lieutenant Colonel in 1827. Charles was Surveyor-General of the Ordnance from 1832 to 1834, in 1841, and again from 1846 to 1852, with the responsibility of ensuring the ordnance (weapons and ammunition) the British Army received was of good quality. He was promoted to Major-General in 1846, Lieutenant-General in 1854, and General in 1863. From 1865 to until he died in 1873, Richard served as the commander of the 57th (West Middlesex) Regiment of Foot, a line infantry regiment in the British Army.

Charles was also active in working for the Whig Party on a local level. In 1831, he was elected to Parliament and served for a total of ten years over several periods. Mary and Charles’ home Little Holland House Holland became a famous meeting place for prominent Whig politicians.

Lady Mary Fox, aged 65, died on July 13, 1864, in London, England. Her husband Charles survived her by nearly nine years, dying at the age of 76, on April 13, 1873, in London. They are both buried at Kensal Green Cemetery in London, England.
