By the time her marriage to Spencer was dissolved, Wallis had become involved with Ernest Aldrich Simpson, an Anglo-American shipping executive and former officer in the Coldstream Guards. He divorced his first wife, Dorothea (by whom he had a daughter, Audrey), to marry Wallis on 21 July 1928 at the Register Office in Chelsea, London. Wallis had telegraphed her acceptance of his proposal from Cannes where she was staying with her friends, Mr and Mrs Rogers.  The Simpsons temporarily set up home in a furnished house with four servants in Mayfair. In 1929, Wallis sailed back to the United States to visit her sick mother, who had married legal clerk Charles Gordon Allen after the death of Rasin. During the trip, Wallis's investments were wiped out in the Wall Street Crash, and her mother died penniless on 2 November 1929. Wallis returned to England and with the shipping business still buoyant, the Simpsons moved into a large flat with a staff of servants.  Through a friend, Consuelo Thaw, Wallis met Consuelo's sister Thelma, Lady Furness, the then-mistress of Edward, Prince of Wales. On 10 January 1931, Lady Furness introduced Wallis to the Prince at Burrough Court, near Melton Mowbray. The Prince was the eldest son of King George V and Queen Mary, and heir apparent to the British throne. Between 1931 and 1934, he met the Simpsons at various house parties, and Wallis was presented at court. Ernest was beginning to encounter financial difficulties, as the Simpsons were living beyond their means, and they had to fire a succession of staff.
