Susanna Keir Wikipedia
Susanna Keir, née Harvey (1747-1802) was a British novelist. Her two novels, "largely in epistolatory form, are long on moralizing and short on action."
Susanna Harvey married the chemist and poet James Keir, a friend of Erasmus Darwin and Joseph Priestley and supporter of the French Revolution. Though his manufacturing business was based in Birmingham and Dudley, she wrote her novels living in Edinburgh. The couple had one child, Amelia, who wrote a privately printed biography of her father in 1859.("by a lady") Interesting Memoirs, 1785.
