As soon as an intimation of the Royal Marriage Act reached the Duke of Gloucester, he informed the King of his marriage, and further acquainted him with an impending interesting event at which he desired the great officers of state should attend. The news was a great blow to George, who at first took no notice of his brother's communication; but upon receipt of a second letter deigned to state that after the birth of a child he would send and have "the marriage, as well as the birth enquired into, in order that both may be authenticated." This was most unsatisfactory to the Duke and his wife, and the former, to the general astonishment, rose to the occasion, and sent a dignified reply, in which he demanded an immediate inquiry, otherwise he would state his case in person in the House of Lords. The threat produced the desired result, inquiries were made, and as the marriage was informal, though not actually illegal, it was only after the Duke's avowed intention to go through the ceremony again that the King accepted the marriage. His consent was given on May 27, and two days later a child was born.[143] [143] William Frederick succeeded his father as Duke of Gloucester, 1805; married Princess Mary, fourth daughter of George III, 1816. Though the King could not refuse to recognize the marriage of his brothers, he could and did decline to receive the parties to them, and for some years the two Dukes and their wives were in disgrace. The Duke and Duchess of Gloucester bore their exile with equanimity, for the Duke was passionately fond of travelling and perhaps never so happy as when roaming over the continent. He was the King's favourite brother,[144] and was eventually received into favour, when the King could not well refrain from pardoning the other transgressor. "You have heard, I suppose, of the conduct of the two duchesses about their husbands' reconciliation with the King," Lady Sarah Bunbury wrote to Lady Susan O'Brien, in the summer of 1780. "The Duchess of Cumberland sent her husband to Court, and said that she would be no hindrance to his going, 'that her house was her palace, and her husband her guard, and she wanted no others.' _Voyez un peu comme elle s'y prend bien pour arriver à sa fin._ The Duke of Gloucester goes only in private, but yet the King is so fond of him, he seems to approve of everything he does, so that it's hard to tell who is in the right, but I would bet my money on the head of a Luttrell being in the right road to preferment, and it's no bad sign of it when a Luttrell adopts _les beaux sentiments_ and is scrupulous of family duties among relations, for it is not in that line they have hitherto shone."
