Elizabeth Whitlock (née Kemble; 2 April 1761, Warrington, Lancashire – 27 February 1836, Addlestone) was an English actress, a member of the Kemble family of actors. She made her first appearance on the stage in 1783. In 1785 she married Charles E. Whitlock, went with him to America, and played with much success there. She seems to have retired about 1807. Her sister was actress Sarah Siddons.
John Philip Kemble (1 February 1757 – 26 February 1823) was a British actor. He was born into a theatrical family as the eldest son of Roger Kemble, actor-manager of a touring troupe. His elder sister Sarah Siddons achieved fame with him on the stage of the Theatre Royal, Drury Lane. His other siblings, Charles Kemble, Stephen Kemble, Ann Hatton, and Elizabeth Whitlock, also enjoyed success on the stage.
Sarah Siddons (née Kemble; 5 July 1755 – 8 June 1831) was a Welsh actress, the best-known tragedienne of the 18th century. Contemporaneous critic William Hazlitt dubbed Siddons as "tragedy personified".
She was the elder sister of John Philip Kemble, Charles Kemble, Stephen Kemble, Ann Hatton, and Elizabeth Whitlock, and the aunt of Fanny Kemble. She was most famous for her portrayal of the Shakespearean character Lady Macbeth, a character she made her own.
