While in Washington D.C., Elizabeth Lindsay planted the gardens of the new Edwin Lutyens designed British Embassy which was the setting for the famous tea party for King George VI and his wife Queen Elizabeth, the first reigning monarchs from the United Kingdom to visit North America.

Elizabeth Hoyt lived in Oyster Bay (town), New York with her brothers; Sherman became the first world-class American yachtsman.

Beginning in 1909 for two seasons, determined to become a landscape architect at a time when formal training was not opened to women, Elizabeth Hoyt studied botany and horticulture at the Arnold Arboretum in Massachusetts, under the supervision of the head, Charles Sprague Sargent.

In October 1914, after touring and studying gardens both in Europe and the United States, Hoyt set up her own business in New York, first at 171 Madison Avenue, later at 38 East 11th Street.

Draper and Hoyt were sent to France in July 1917 to undertake the standardization of hospital garment and dressings and to survey working conditions of women.

By October 1917, upon returning to the Red Cross headquarters in Washington, Hoyt became head of the newly created United States Women's Bureau.

[6][7] Following the death of Henry Adams on 27 March 1918, and then of her cousin, Martha Lindsay on 28 April 1918, Hoyt arranged for another assignment in France in order to visit her aunt living in England.

[9] Hoyt married Ronald Charles Lindsay, the widower of her cousin, in the chapel of Stepleton House, at Blandford, Elizabeth Cameron's home in Dorset, England.

[18] Lady Lindsay's ashes were interred next to or near the grave of her mother in Lake View Cemetery in Cleveland, Ohio.

Sir Ronald, his first wife, Martha, and her mother Elizabeth Cameron are all under one gravestone, behind the estate's pre-Norman chapel, St. Mary's.
