British-born novelist, children's playwright, and poet, educated in Point Levy, Quebec, and Sarnia, Ontario, where she and her sisters operated a school for ladies, Walker published poetry widely in newspapers on both sides of the border before collecting them in Leaves from the Backwoods in 1861-62. She returned to England to work for her cousin, Margaret Oliphant, a well-known novelist, and edited her Autobiography and Letters in 1899 (Leicester: Leicester University Press, 1974; PR 5114 A3 Robarts Library), this time under her married name, Mrs. Harry Coghill. She collected her poetic output in Oak and Maple: English and Canadian Verses (London: Kegan Paul, 1890; CIHM microfiche 696 Robarts Library).
