Helen Taylor was born in Shoreditch, London on 27 July 1831 and died in Torquay. The daughter of John and Harriet Taylor, both religious dissenters, members of the Unitarian church under the ministry of William J. Fox, at South Chapel in Finsbury, Helen Taylor grew up with two brothers, Herbert, the elder, and dear Haji (Algernon), in an upper middle-class home supported by John Taylor's prosperous business. He encouraged his daughter's propensity for reading ancient and modern history, English and French literature, philosophy and polemics, and eclectic intellectual curiosity that was enhanced by extensive travel in England and Europe with her mother. As a young adult her education expanded under the continuing guidance of her mother, and then by John Stuart Mill, who became her stepfather when Harriet and John married two years after John Taylor's death in 1849.
