A singing teacher introduced her to theatrical producer George Edwardes, which led to roles at the Gaiety Theatre, London.
[2] Morrell played roles in the Edwardian musical comedies A Greek Slave (1898–1899),[3] San Toy (1900),[4] A Country Girl (1902–1904), The Catch of the Season (1904–1906), Sergeant Brue (1904), Under a Panama (1904),[5] The Talk of the Town (1905), and The Spring Chicken (1905).
[7][8] As a Gaiety Girl, Morrell's appearance and gowns were at least as reviewed as her talents, and she was a popular subject for photo postcards.
[2][11] The press interest in her appearance continued: "She is distinctly English, with her lovely complexion of milk and roses, a skin as fine as a baby's, straight delicate features, and good grey eyes", wrote one interviewer in a Melbourne newspaper, continuing to describe her teeth ("perfect"), her smile ("bewitching"), her eyebrows, her hair, her height, and her dress.
[13][14] In 1909 the couple had a daughter, Mary Wentworth Kelly, and in 1911 they were living with four servants in Knightsbridge in London.
