In 1868 Leclercq played Eliza in Boucicault's After Dark and Kate Jessop in his Lost at Sea; in 1875 she was the first Clara Ffolliott in The Shaughraun. Over the next twenty years she appeared in new and classic roles, the latter including Olivia in Twelfth Night with Henry Irving and Ellen Terry. Her roles in new plays included Marie Leczinska in W. G. Wills's The Pompadour (1888), and Lady Wargrave in Sydney Grundy's The New Woman towards the end of 1894.
