The marriage, which originally was to have been celebrated in June, was now moved forward to the first of May so Charles's enemies in the parliament would not have time to marshall their forces, and delay or prevent the match. The duke of Buckingham was to have acted as the king's proxy at the June celebration, but now he had to remain in England to attend the old king's funeral, which was set for the end of April, for it was not unusual for a king to lie in state several weeks. Instead, the due de Chevreuse would act as the English king's proxy. Chevreuse was related to both the French royal house and the English, through their mutual ancestor, the due de Guise. He was therefore a suitable choice, and acceptable to both sides.

Most of the English court remained in England, but Charles had asked the duke of Glenkirk and his family to attend his wedding. It would be a far more pleasant occasion than poor old Jamie's funeral, the duke conceded to his wife, and if his sister, the duchesse de St. Laurent, would ask their mother to come from Naples for a visit, Jasmine and the children could at least meet Catriona Hay Leslie Stewart-Hepburn.

The young king's reason was more personal. James Leslie himself was distantly related to Charles, and his stepson, little Charles Frederick Stuart, was the new monarch's nephew, although he had been born on the wrong side of the blanket. Such accidents of birth did not matter to the Stuarts except where the succession was concerned. They had always welcomed, recognized, and considered their bastards legitimate members of their clan. The king wanted some of his family blood at his wedding ceremony, and the Leslies of Glenkirk would acquit themselves, and therefore the Stuarts, quite well. They were also not important enough to be missed at the official mourning ceremonies since they only rarely came to court.
