J. M. (Josephine Martin) Callwell

Born in Ireland in 1856, Josephine Mary Callwell wrote under the name J. M. Callwell. Reliable library and reference sources describe her as an Irish author noted especially for juvenile and historical works.

Her known books include Legends of Olden Times (1880), The Squire's Grandson (1888), Dorothy Arden (1889), Town and Country Mice (1891), The Rival Princes (1893), and A Champion of the Faith (1894). The range of those titles suggests a writer comfortable moving between stories for children and fiction shaped by historical settings.

Callwell never married, and she died on February 16, 1935, in Ballycastle, County Antrim. A freely available later title, A Little Irish Girl, has helped keep her work visible for modern readers discovering older children's fiction.
