Mary Ann Kilner

Mary Ann Kilner (née Maze) (1753–1831) was a prolific writer of children's books in the late 18th century. The most famous was The Adventures of a Pincushion (c. 1780-1783). Together, she and her sister-in-law, Dorothy Kilner, published over thirty books. Mary Ann published under the name "S. S.", which stood for her home in Spital Square, London.

Mary Ann was born on 14 December 1753 at Spital (then Spittal) Square, London, the youngest child of James Maze (d. 1794), a prosperous Huguenot (i.e. French Protestant) silk throwster and merchant. She was bilingual and said to be very intelligent. Her childhood friends were the siblings Dorothy (1755–1836) and Thomas Kilner (1750–1812). The two girls wrote to one another constantly during their childhood and teenage years. On 18 September 1774 Mary Ann married Thomas and moved to her husband's home at 33 Spital Square. They had five children, of whom Eliza (b. 1776), Frances (b. 1783) and George (born 1791) survived.

Following the appearance of her sister-in-law's The First Principles of Religion in 1780, Mary Ann approached Dorothy's publisher, John Marshall, with her own Familiar Dialogues for the Instruction and Amusement of Children of Four and Five years Old, which Marshall published the following year. Some works of fiction followed: Memoirs of a Peg Top and Jemima Placid in March 1782, and The Adventures of a Whipping Top and William Sedley the following year. She also published A Course of Lectures, for Sunday Evenings: containing Religious Advice to Young Persons in 1783. Her most famous title, The Adventures of a Pincushion, was published late 1783 or early 1784. All of these works were popular and reprinted several times, the last at regular intervals until the 1830s.

Their works were originally published anonymously, but after Dorothy adopted the initials M.P. (representing her home at Maryland Point), Mary Ann used S.S. (for Spital Square).
