Lucy Ellen Guernsey was a 19th-century American author who lived in Rochester, New York. She was a strong proponent of early education and moral development in children, although she never had children of her own. Throughout her most productive years (1855–85) she wrote over 60 novels, most of which were published by the American Sunday School Union. She was an active member of the Rochester community; she founded the first sewing school for working-class children and was involved establishing the Home for Aged Women. She edited a popular religious publication, The Parish Visitor, taught an adult biblical class for Sunday School, and was the president of the Christ Church Missionary Society (1881–85).
