Passages:
Lady Augusta Murray (27 January 1768 – 5 March 1830) was the first wife of Prince Augustus Frederick, Duke of Sussex, the sixth son of George III.  As their marriage was in contravention of the Royal Marriages Act 1772, it was considered legally void, and she could not be styled as the Duchess of Sussex. The Recognition of Customary Marriages Act, 1998 (Act No. 120 of 1998) is a South African statute in terms of which marriages performed under African customary law, including polygynous marriages, are recognised as legal marriages.  It also reformed the law relating to the legal status of women in customary marriages, the financial consequences of a customary marriage and the dissolution of customary marriages, replacing the customary law with statutory provisions.  The act was signed by President Nelson Mandela on 20 November 1998 but only came into force on 15 November 2000. Sir Augustus Frederick d'Este, (13 January 1794 – 28 December 1848) was the son of Prince Augustus Frederick, Duke of Sussex, and Lady Augusta Murray, and a grandson of King George III.  His parents were secretly married on 4 April 1793, in a Church of England ceremony in the Hotel Sarmiento, Rome, and later married again on 5 December 1793 at St George's, Hanover Square, Westminster, using their correct names but without revealing their identities.  Both marriages were in defiance of the Royal Marriages Act 1772 and were thus legally null and void, at least in English law.  After the birth of their first child, the marriage was discovered by the King and formally annulled, making their son illegitimate in Great Britain. The Royal Marriages Act 1772 was an act of the Parliament of Great Britain, which prescribed the conditions under which members of the British Royal Family could contract a valid marriage, in order to guard against marriages that could diminish the status of the royal house.  The right of veto vested in the sovereign by this act provoked severe adverse criticism at the time of its passage.  It was repealed on 26 March 2015 as a result of the 2011 Perth Agreement.  Its provisions were replaced by more limited restrictions that apply only to the first six people in the line of succession (currently Prince Charles, Prince William, Prince George, Princess Charlotte, Prince Harry, and Prince Andrew). Colonel George William Adolphus FitzGeorge (24 August 1843 – 2 September 1907) was a great-grandson of King George III of the United Kingdom and first cousin to Queen Mary, being the eldest of the three sons of the 2nd Duke of Cambridge and Louisa Fairbrother (the other sons were Admiral Sir Adolphus FitzGeorge and Colonel Sir Augustus FitzGeorge).  As his parents were married in contravention of the Royal Marriages Act 1772, he was ineligible to succeed his father as Duke of Cambridge and along with his siblings did not hold royal titles. Prince Henry, Duke of Cumberland and Strathearn (Henry Frederick; 7 November 1745 – 18 September 1790) was the sixth child and fourth son of Frederick, Prince of Wales and Augusta of Saxe-Gotha, and a younger brother of George III.  His 1771 marriage to a commoner against the King's wishes prompted the Royal Marriages Act of 1772 . The Royal Berkshire Regiment (Princess Charlotte of Wales's) was a line infantry regiment of the British Army in existence from 1881 until 1959.  The regiment was created in 1881, as the Princess Charlotte of Wales's (Royal Berkshire Regiment), by the amalgamation of the 49th (Princess Charlotte of Wales's) (Hertfordshire) Regiment of Foot and the 66th (Berkshire) Regiment of Foot.  In 1921, it was renamed the Royal Berkshire Regiment (Princess Charlotte of Wales's). Sarah Fairbrother (calling herself "Louisa" and known from 1859 as "Mrs FitzGeorge"; 31 October 1816 – 12 January 1890) was an English actress and the mistress of Prince George, Duke of Cambridge, a male-line grandson of George III.  As the couple married in contravention of the Royal Marriages Act 1772, their marriage was not recognised under the law. Cecilia Underwood, 1st Duchess of Inverness (née Lady Cecilia Letitia Gore; c. 1785 – 1 August 1873) was the second wife of Prince Augustus Frederick, Duke of Sussex, sixth son of King George III.  As their marriage was in contravention of the Royal Marriages Act 1772, it was considered legally void, and she could not be styled either as the Duchess of Sussex nor a Princess.  She was created Duchess of Inverness, in her own right, by Queen Victoria, on 10 April 1840. Princess Charlotte of Cambridge (Charlotte Elizabeth Diana; born 2 May 2015) is the younger child and only daughter of Prince William, Duke of Cambridge, and Catherine, Duchess of Cambridge.
