Catharine Parr Traill, born Strickland (9 January 1802 – 29 August 1899) was a British-Canadian author who wrote about life as a settler in Canada. She born Catherine Parr Strickland in Rotherhithe in 1802, sister to authors Agnes Strickland, Susanna Moodie, and Elisabeth Strickland, Traill began writing children's books in 1818, after the death of her father. Her early work, such as Disobedience, or Mind What Mama Says (1819), and "Happy Because Good", were written for children, and often dwell on the benefits of obedience to one's parents. A prolific author, until her marriage she averaged one book per year. In 1832, she married Thomas Traill, a retired officer of the Napoleonic Wars and a friend of her sister's husband, John Moodie, despite objections from her family (aside from Susanna). Soon after their marriage they left for Canada, settling near Peterborough, Upper Canada, where her brother Samuel was a surveyor. She described her new life in letters and journals, and collected these into The Backwoods of Canada (1836), which continues to be read as an important source of information about early Canada. She describes everyday life in the community, the relationship between Canadians, Americans, and natives, the climate, and local flora and fauna. More observations were included in a novel, Canadian Crusoes (1851). She also collected information concerning the skills necessary for a new settler, published in The Female Emigrant's Guide (1854), later retitled The Canadian Settler's Guide. After suffering through the depression of 1836, her husband Thomas joined the militia in 1837 to fight against the Upper Canada Rebellion. In 1840, dissatisfied with life in "the backwoods", the Traills and the Moodies both moved to the city of Belleville. While Susanna was more concerned with the differences between rural and urban life, Catharine spent her years in Belleville writing about the natural environment. She often sketched the plant life of Upper Canada, publishing Canadian Wild Flowers (1865) and Studies of Plant Life in Canada (1885). She died in Lakefield, Ontario in 1899. Trent University, in Peterborough, Ontario, named their Catharine Parr Traill College campus after her.
