Grace Campbell Stewart (died 1863) was a British miniature painter.
Stewart was one of the daughters of Anthony Stewart, 1773–1846, a portrait and miniature painter from Crieff in Perthshire and of Janet Weir whose father, Alexander Weir, was also a painter.[1] Their father taught both Grace and her elder sister, Margaret Seguier, to paint.[1] After moving to London, where she lived in Clapham for a long period, Grace Stewart built a reputation as a fine miniature painter.[2] Between 1843 and 1856 she exhibited 14 works at the Royal Academy in London.[3] [2] These were mostly portrait miniatures of members of the Scottish nobility including the children of John Scott, 2nd Earl of Eldon and his wife Louisa.[1] [2]
