Susan Johnstone, also known as Mrs. James William Wallack (29 November 1792[1] - 25 December 1850) was an English-American actress of the 19th-century.
She was born as Georgiana Susannah Johnstone in Covent Garden in London in 1792, the only daughter of the actor, singer and comedian John Henry Johnstone (1749-1828), known as 'Irish' Johnstone with his second wife Ann Bolton (1771-1810), the daughter of a wine merchant, with whom he eloped.[2] [3] On the day of her baptism on 6 March 1793 Richard Barry, 7th Earl of Barrymore was to have been her sponsor but he was killed in a shooting accident the same day.[4] On going on the stage herself she enjoyed a successful career and excelled in comic roles. In 1817 she married the actor and theatrical producer James William Wallack at Lambeth in 1818,[5] appearing with him in New York and on tour.[6] The couple appeared in the United States frequently thereafter. They had four sons: John Johnstone Wallack, known as Lester Wallack, who also became an actor;[7] (1820–1888); James Price Wallack (1821–1846); Captain Henry Jobling Wallack (1823–1900), and Charles Saville Wallack (1826–1855). Her portrait was painted several times including by Henry Inman in about 1828, one of a small series he painted of theatrical figures. Another by Thomas Sully entitled 'Portrait of Mrs. Wallack' was exhibited at the Pennsylvania Academy of the Fine Arts in 1819.[8]
Susan Johnstone Wallack died suddenly in St. Giles in London in 1850.
