On the Continent, Adelaide became pregnant, but in her seventh month of pregnancy, she caught pleurisy and gave birth prematurely on 27 March 1819 at the Fürstenhof Palace in Hanover. Her daughter, Charlotte Augusta Louise, lived only a few hours. Another pregnancy in the same year caused William to move the household to England so his future heir would be born on British soil. However, Adelaide miscarried at Calais or Dunkirk during the journey on 5 September 1819. Back in London, they moved into Clarence House, but preferred to stay at Bushy House near Hampton Court, where William had already lived with Dorothea Jordan. She became pregnant again, and a second daughter, Elizabeth Georgiana Adelaide, was born on 10 December 1820 at St James's Palace. Elizabeth seemed strong but died less than three months old on 4 March 1821 of "inflammation in the Bowels". Ultimately, William and Adelaide had no surviving children. Twin boys were stillborn on 8 April 1822 at Bushy Park and a possible brief pregnancy may have occurred within the same year.
