Deborah Darby (25 August 1754 – 14 February 1810) was a British Quaker minister and traveller based in Coalbrookdale, Shropshire.
Under her and William Savery's influence he decided to join the Society of Friends and he became an important figure in the Quaker movement.
Darby, Savery and Grellet became friends and when Darby returned to Britain with Rebecca Young she was accompanied by four American Quakers (including William Savery) and her friend Stephen Grellet was there to wave them off.
Elizabeth Fry who was trying to plan her life[3] was staying with Gurney in the hope that her steadying influence might assist her.
[3] She would later credit William Savery, Darby and Gurney with influencing her decision to devote her life to good works.
