Lady Barbara Montagu (1722–1765) was the daughter and one of the seven surviving children of George Montagu, first Earl of Halifax, and his second wife, Lady Mary Lumley. She was a cousin of Edward Montagu. Lady Bab (as she was always called) suffered from poor health and spent most of her adult life in Bath, Somerset, where she met Sarah Scott as early as December 1747. Lady Bab and Scott were fast friends, and, apart from their brief residence in Leicester Fields, London, after Scott’s marriage to George Lewis Scott in June 1751, the women lived together in Bath and Batheaston, Somerset, until Lady Bab’s death in August 1765. Despite their small incomes, Lady Bab and Scott participated in a variety of charitable activities: they instructed children, employed disabled servants, donated clothing, and sold handicrafts for the benefit of the less fortunate. Lady Bab also supported Scott’s publishing activities and those of their friends: she subscribed to Sarah Fielding’s books, and, with Samuel Richardson’s help, she published The Histories of Some of the Penitents in the Magdalen-House (1760) and a series of educational cards. Lady Bab died in Bath on 19 August 1765 and was buried at the Church of St. Mary in Charlcombe, Somerset. Beneficiaries of her will included not only her brother, sisters (Lady Anne Jekyll and Lady Elizabeth Archer), and Scott, but also her servants and friends, Fielding, Elizabeth Cutts, Mary Arnold, and Sarah Maese among them.
