In January 1949, the princess founded a nursing order of Greek Orthodox nuns, the Christian Sisterhood of Martha and Mary, modelled after the convent that her aunt, the martyr Grand Duchess Elizabeth Feodorovna, had founded in Russia in 1909. She trained on the Greek island of Tinos, established a home for the order in a hamlet north of Athens, and undertook two tours of the United States in 1950 and 1952 in an effort to raise funds. Her mother was baffled by her actions, "What can you say of a nun who smokes and plays canasta?", she said. Her daughter-in-law became queen of the Commonwealth realms in 1952, and Princess Andrew attended her coronation in June 1953, wearing a two-tone grey dress and wimple in the style of her nun's habit. However, the order eventually failed through a lack of suitable applicants.
