On 15th December 1785 King George IV of Great Britain and Ireland [aged 23] and Maria Anne Smythe aka "Mrs Fitzherbert" [aged 29] were married secretly in the drawing room of her house in Park Street, London; her third marriage, his first. The marriage was invalid under English civil law because his father had not given his consent. Her uncle Henry Errington and her brother John Smythe were witnesses. The ceremony was performed by one of the prince's Chaplains in Ordinary, the Reverend Robert Burt, whose debts of £500 were paid by the prince to release him from Fleet Prison [Map] to preside at the ceremony.. He the son of King George III of Great Britain and Ireland [aged 47] and Charlotte Mecklenburg Strelitz Queen Consort England [aged 41].
On 8th April 1795 [her father] King George IV of Great Britain and Ireland [aged 32] and [her mother] Caroline of Brunswick Queen Consort England [aged 26] were married at Chapel Royal, St James's Palace. He the son of [her grandfather] King George III of Great Britain and Ireland [aged 56] and [her grandmother] Charlotte Mecklenburg Strelitz Queen Consort England [aged 50]. They were first cousins. She a great granddaughter of King George II of Great Britain and Ireland.
On 7th January 1796 Princess Charlotte Augusta Hanover was born to King George IV of Great Britain and Ireland [aged 33] and Caroline of Brunswick Queen Consort England [aged 27] at Cartlon House. Coefficient of inbreeding 6.51%.
In 1813 Catherine Anguish Duchess Leeds [aged 48] was appointed Governess to Princess Charlotte Augusta Hanover [aged 16].
On 6th November 1817 Princess Charlotte Augusta Hanover [aged 21] died in childbirth at Claremont House Esher, Surrey. She buried at St George's Chapel, Windsor Castle [Map].
On 13th February 1818 Richard Croft 6th Baronet [aged 56] shot himself as a consequence of the death of Princess Charlotte Augusta Hanover to whom he had been physician during her labour. A copy of Shakespeare's Love's Labour's Lost was found open with the passage (Act V, Scene II): "Fair Sir, God save you! Where is the Princess?". He was buried at St James' Church, Piccadilly.His son Thomas [aged 19] succeeded 7th Baronet Croft of Croft Castle in Herefordshire.
Adeline Horsey Recollections. After my dear mother's [aged 43] death I visited a great deal with my father [aged 53], and one year we went for the shooting to Lord Huntingfield's place, Heveningham Hall, Suffolk. I slept in the bedroom once occupied by the famous Chevalier d'Éon, who had been a frequent guest at Heveningham, and about whom there were many stories told. It was said that the Chevalier was the one and only lover of cross-grained [her grandmother] Queen Charlotte, and that her son, George IV, was the result of their intimacy, although his paternity was of course admitted by King George III. The animosity always displayed by the old Queen to her grand-daughter, Princess Charlotte, was supposed to arise from the fact that as heiress to the throne she innocently dispossessed the other Royal Dukes from the succession. It is certainly a fact that the Princess's untimely death in childbirth was attributed to foul play at the time, and when later the accoucheur [obstetrician] Sir Richard Croft, committed suicide, all classes of society were loud in condemnation of the Queen and the Prince Regent. I do not vouch for the accuracy of Queen Charlotte's love affair. I only give the Heveningham gossip as I heard it.
Note A. D'Eon was undoubtedly one of the most picturesque and mysterious personages of the eighteenth century I was naturally interested in these somewhat scandalous stories.
The Chevalier died when he was eighty-three years of age, after a most extraordinary career. He was at one time aide-de-camp to the Comte de Broglie, and fought in the French army; but later on for some mysterious reason he discarded man's attire and passed as a woman for thirty-four years. Often when I went into my room I half expected to see a ghostly figure seated at the escritoire where the Chevalier wrote his secret cipher communications, and I wondered whether the brocade crowns and frills and furbelows that he wore as a woman had ever hung in the old wardrobe which I used.
My father and I also stayed with the Westmorlands at Apethorpe Hall; we visited the Earl [aged 38] and Countess of Chichester [aged 36] at Stanmer Park, and we were welcome guests at Cadlands, Silverlands, Chiswick House, West Park, and my uncle Lord Stradbroke's place, Henham Hall, which was afterwards burnt down.
I had visited Deene Park, Northamptonshire [Map] with my mother in 1842, but I must deal with my future home in the chapter devoted to Deene and its associations.
Diary of the Times of George IV Volume 1 Section 1. To-day, I had the honour of meeting the Princess Charlotte, at her [her grandmother] grandmother's. She is very clever, but has at present the manners of a hoyden school girl; she talked all sorts of nonsense to me; she is a fine piece of flesh and blood, but can put on dignity when she chooses, though it seems to sit uneasily upon her. What will be her fate? It is impossible not to feel an interest in any human being upon whom such a weight of responsibility is placed.
