[3] Marguerite Hedman adopted the name "Marguerite Leslie" as an actress in London,[1] where she appeared in Nero (1906), The Beauty of Bath (1906-1907), My Darling (1907), Concerning a Countess (1907),[4] A Scotch Marriage (1907-1908), Penelope (1909),[5] Preserving Mr. Panmure (1911), The Marionettes (1911-1912), At the Barn (1912), and The Vision of Delight (1912).

[8] She also appeared in four silent films, Jim the Penman (1915, now lost), The Question (1916), The Mite of Love (1919, a short), and The Chosen Path (1919).

[9] She was tall,[10] and considered a beauty as a young actress,[3] a "Burne-Jones girl in an English garden-party hat... quite the pinkest and whitest, fresh daisiest thing we have had for a long while," mused one Los Angeles writer.
