Lady Augusta Murray, Duchess of Sussex, writes to her son Augustus Frederick 1807

In 1802 George the Third promoted his youngest son Augustus Frederick to the Dukedom of Sussex. In the normal course of things his wife Augusta would have become the Duchess of Sussex, his eight-year-old son would be known as Prince Augustus Frederick, and his one-year-old daughter as Princess Augusta Emma. Unfortunately, Frederick had married in 1793 without his father’s consent, required by the Royal Marriages Act of 1772, and George acted swiftly to get his disobedient son’s marriage annulled, leaving Lady Augusta Murray to give birth out of wedlock in 1794 and again in 1801. George was more tolerant of his sons who had children in extra-marital relationships, most clearly true of the Duke of Clarence, later William IV, who had ten acknowledged children by the actress Dorothea Jordan and one other child by a different partner. The Prince of Wales, later George IV, almost certainly had children born to mistresses though except perhaps in one case the list continues to be disputed.

Prince Augustus Frederick always considered himself married and though he abandoned Augusta in 1800 did not re-marry until after her death in 1830. Augusta never abandoned the claim to be married to the king’s son and never re-married, though she had a third child Henry (1805-1824) - about whose life I can trace almost nothing - in the course of a long adulterous relationship with Lord Archibald Hamilton which appears to have precipitated the breach with her husband. Nonetheless, she continued to self-identify as wife of the king’s son and when he became Duke of Sussex began to style herself Duchess of Sussex and her children as Prince and Princess. This infuriated the King and his court and they set about making Augusta’s already difficult life more difficult with some kind of compromise only arrived at in the period 1806-1809: her debts were cleared, she got a pension and title (Lady D’Ameland) but lost control over the education of her son. All this has been explored at length, most recently in Julia Abel-Smith’s Forbidden Wife (2020).

She was supported by her own family headed by her father the Earl of Dunmore and was able to make a home for herself in the busy port and fashionable resort of Ramsgate, eighty miles east of London and overlooking the English Channel. There she occupied a fairly modest house, Mount Albion, set in grounds which she extended and carefully attended to. It was a home for her children. In Ramsgate her self-identification was always accepted as local newspaper announcements indicate: The British Press of 31 July 1804 recorded that “Ramsgate is expected to be this season uncommonly full …. The Duchess of SUSSEX (LADY AUGUSTA MURRAY) arrived here last week, to pass the season with us”; The Oracle and the Daily Advertiser for 7 December 1805 records the departure of “The Duchess of SUSSEX and family, from Ramsgate to Lower Grosvenor-street”. A seasonal Duchess - even a scandalous one - was an enhancement both to the splendour and prosperity of Ramsgate.

Elizabeth Grant recorded her childhood memories of holidaying next door to the family in her Memoirs of a Highland Lady (1898), describing Augusta’s two children as “a boy and a girl, fine, large handsome young people, unduly imbued with the grandeur of their birth. She never committed herself by calling herself or them by any title: “My boy, my girl”, she always said in speaking of or to them. The servants, however, mentioned them as the Prince and Princess, as did all the acquaintances who visited the house” 1.

The Ramsgate post office would have had no difficulty in delivering the 1807 letter I recently discovered, the address panel of which is my Exhibit A and the contents of which are transcribed below.

 

 

 

It is written by Augusta to her son addressed as “Prince Augustus Frederick”, exactly the kind of thing to which the Court objected. It may be a concession that the seal on the reverse does not bear the royal arms but is simply inscribed with a letter “A”.

The address panel repays some forensic attention. In Britain until the 1840s postage was generally paid by the recipient and General Post Office charges were high. But some people - members of both Houses of Parliament and so on – could claim “Free Frank” privileges using a standard formula: top of the address panel, write full date and place of despatch, in this case “1807 London August twenty nine”; then bottom left sign your name in a consistent style which identifies this sender as Lord Archibald Hamilton, younger son of the Duke of Hamilton, and since 1802 MP for Lanarkshire. But on this occasion he is providing a service for Augusta by adding his signature to a letter written in another hand, a very common favour. She may have been living or staying in his house and, if not, then with her parents nearby. In the letter she writes that she has driven a horse several times around the sqre. Unfortunately for me, both Hamilton’s house and the Dunmore’s home boasted a nearby square. Whether she was caring for her third child Henry I also do not know. The letter when handed to a postal clerk was stamped in red to confirm that no delivery charges should be levied; in this instance the handstamp topped with a crown is just visible in the middle.

The contents of the letter are in her characteristic spontaneous and direct style, something which can be confirmed from other letters and notebooks by Augusta held by the Royal Collections Trust which always refers to her as “Lady Augusta Murray” 2. Augusta uses the word “Treasures” frequently to characterise her children.

Augusta had loyal servants who stayed with her for years even through financial difficulties which left bills unpaid. At the end of her letter she sends greetings to “Mrs Jones” who is clearly in charge of her older son; at the same time a “John” sends his love to his “Mammy” and I take this to be a John Jones who is employed by Augusta in London. Mrs Jones may well be the Mary Jones who appears in December 1793 as witness to the unlawful marriage of Augusta at St George’s Hanover Square; she was a dressmaker for Augusta’s family; her husband, who served as second witness, was a coal merchant. I have attempted unsuccessfully to find out more about this relationship with the Joneses which seems to have endured and been important to both parties.

In 1830 Augusta’s son was eventually granted a sinecure and the title of Sir Augustus d’Este by a sympathetic Willaim IV. His adult life was limited and shortened by muscular dystrophy but included active involvement with the London-based Aborigines’ Protection Society. It is in that connection that the second letter in my possession is written to him from Canada with whose indigenous populations he concerned himself 3.

A mausoleum, now derelict and graffitied, was erected in Ramsgate by Augustus and contains his remains along with those of his mother and her parents and his own sister Emma, later Lady Truro. The title of Duke of Sussex became dormant in 1843 when George the Third’s youngest son died but was revived in 2018.

My dearest good for nothing Boy I write to you tho’ you do not deserve it, but you know from Experience that mothers do not always act towards their children as they deserve – they are too much guided by affection to be wise, & this is my case at present. I expected that the day you were confined to your Room I should have heard from you, but I was mistaken – you never thought once of writing to me tho’ I had even complained of your silence; My Girl must behave better than this, - or I shall begin to believe what I have often heard – that it is a great error to love one’s children too well, - that it makes them ungrateful, instead of producing love in their hearts, love of duty. My own most dear, & for long only loved Treasure pray never let Mama feel like this. – I was very sorry not to be able to leave London this morning, - but on Monday, I do hope & trust nothing shall prevent my being with you at about six, or seven o clock in the Evening. – you have never informed me of the arrival of your Trunk, - that Trunk which I myself packed, according to your desire, the very next day of my arrival, & most of the day following that, I do hope you have received it. – The Coachman has just brought me a most magnificent Horse for driving I drove it several times around the sqre. & thought it too frisky – however the Coachman was so delighted with it that I have consented to his buying it for Mammy, but I don’t think she will allow anyone to be with her when she drives it …... – do you continue to study Mathematicks – I don’t remember yr. having an Euclid but you can get one at Burgess’s [a Ramsgate bookseller]. Pray give my love to dearest little Correspondent [his sister Emma] & Mrs Jones. Adieu my Treasure – John sends his love to his Mama & you … God bless my Treasures.
