On 23 June 1794, Fitzherbert was informed by letter that her relationship with the Prince was over. George told his younger brother, the Duke of York, that he and Fitzherbert were "parted, but parted amicably", conveying his intention to marry their first cousin, Duchess Caroline of Brunswick. According to King George III it was the only way out of a hole: his heir apparent's enormous debts of £600,000 would be paid the day he wed. So the Prince married Caroline on 8 April 1795. However, in 1796, three days after Caroline gave birth to their daughter, Princess Charlotte of Wales, on 10 January, the Prince of Wales wrote his last will and testament, bequeathing all his "worldly property ... to my Maria Fitzherbert, my wife, the wife of my heart and soul". Although by the laws of the country she "could not avail herself publicly of that name, still such she is in the eyes of Heaven, was, is, and ever will be such in mine". However, this did not lead to a reunion. The Prince finally sought a reconciliation with his "second self" during the summer of 1798. By then, he had separated from Caroline for good and was bored with his mistress, Frances Villiers, Countess of Jersey.
