Edward Weld of Lulworth Castle was the eldest of the four sons and one daughter of Edward Weld and his wife Dame Maria née Vaughan. He was heir to the enormous Lulworth Estate with its magnificent Jurassic coastline and its castle in the county of Dorset, England and to other estates. He was a member of the well connected notable recusant family and one of the wealthiest people in the kingdom. He was widowed after his first marriage in 1763 to Juliana Petre, daughter of Robert James Petre, 8th Baron Petre, who died in 1772. In 1775 he married the impecunious Maria Smythe, sixteen years his junior and became her little known first husband. Three months after the wedding he fell off his horse and died of his injuries, before having had time to sign his new will. As there was no issue from either marriage, the estate passed to his surviving younger brother, Thomas. Meanwhile, his widow, was left without provision and soon married Thomas Fitzherbert of Swynnerton. Before long, he too died in 1781 but left her well provided for and known to history as "Mrs Fitzherbert". She went on to contract a morganatic marriage in 1785 with the Prince of Wales, the futureGeorge IV.
The trials of his widow
The short-lived connection to Thomas Weld emerged later in his widow Maria's life when she faced implacable opposition regarding the validity of her third marriage, that is, to the Prince of Wales. It came in the person of Lord William Stourton, who was anyway related to her through their mothers, but William and Maria were also related by marriage, William's wife, Catherine Winifred Weld was a niece of Maria's first husband, Edward, and, William's sister the Hon. Charlotte Mary Stourton was married to Catherine Winifred Weld's brother, Joseph Weld. They were always on friendly terms, and she came to place great trust in him. She appointed William one of the executors of her will, and to act for her as her agent in business generally, in her last years. He was also one of her trustees who acted for her in regard to the destruction of her private papers and was a witness on the occasion, 24 August 1833, when she permitted the Duke of Wellington to burn a horde of her private papers concerning her secret marriage to George IV. At her special entreaty a number of documents which she particularly valued, including her marriage certificate, were deposited in Coutts Bank, sealed and witnessed by Stourton. Moreover, Mrs Fitzherbert dictated to Lord Stourton her memoir which he preserved. It contains invaluable evidence about her marriage to the future George IV, and of their years together. On the subject of - whether there were any children of the marriage - she remained reticent as this would have had enormous repercussions on the Royal Succession. Stourton, who attributed her reticence to "natural delicacy" apparently believed that she was implying that there were no children. William at his death entrusted his brother Charles with the task of publishing the truth about the royal marriage. However, Charles was unable to obtain the documents deposited in Coutts Bank, but he used his brother's copy of Maria's memoir as the basis for his biography of Mrs. Fitzherbert, published in 1856. Her nephew-in-law from her marriage to Edward, Cardinal Weld, persuaded Pope Pius VII to declare the marriage to George sacramentally valid.
