Her seventh pregnancy resulted in the birth of a son at 5 a.m. on 24 July 1689 in Hampton Court Palace. As it was usual for the births of potential heirs to the throne to be attended by several witnesses, the King and Queen and "most of the persons of quality about the court" were present. Three days later, the newborn baby was baptised William Henry after his uncle King William by Henry Compton, Bishop of London. The King, who was one of the godparents along with the Marchioness of Halifax and the Lord Chamberlain, Lord Dorset, declared him Duke of Gloucester, although the peerage was never formally created. Gloucester was second in line to the throne after his mother, and because his birth secured the Protestant succession, he was the hope of the revolution's supporters. The ode The Noise of Foreign Wars, attributed to Henry Purcell, was written in celebration of the birth. Other congratulatory odes, such as Purcell's last royal ode Who Can From Joy Refrain? and John Blow's The Duke of Gloucester's March and A Song upon the Duke of Gloucester, were composed for his birthdays in later years. Opponents of the revolution, supporters of James known as the Jacobites, spoke of Gloucester as "a sickly and doomed usurper". Though described as a "brave livlylike boy", Gloucester became ill with convulsions when he was three weeks old, so his mother moved him into Craven House, Kensington, hoping that the air from the surrounding gravel pits would have a beneficial effect on his health. His convulsions were possibly symptomatic of meningitis, likely contracted at birth and which resulted in hydrocephalus. As was usual among royalty, Gloucester was placed in the care of a governess, Lady Fitzhardinge, and was suckled by a wet nurse, Mrs. Pack, rather than his mother. As part of his treatment, Gloucester was driven outside every day in a small open carriage, pulled by Shetland ponies, to maximise his exposure to the air of the gravel pits. When the effectiveness of this treatment exceeded their expectations, Princess Anne and her husband acquired a permanent residence in the area, Campden House, a Jacobean mansion, in 1690. It was here that Gloucester befriended Welsh body-servant Jenkin Lewis, whose memoir of his master is an important source for historians. Throughout his life, Gloucester had a recurrent "ague", which was treated with regular doses of Jesuit's bark (an early
