Turnbull was the youngest of two daughters born to Alexander Halliday Sligh, an immigrant from Scotland, and Lucinda Hannah McConnell, whose family was among earlyScotch-Irish settlers inWestmoreland County, Pennsylvania. Turnbull attended the village school, a boarding school called Washington Female Seminary in'Little Washington', then enrolled at Indiana State Teachers College (nowIndiana University of Pennsylvania or IUP). Turnbull graduated from IUPPhi Beta Kappa and as valedictorian for the class of 1910. She also attended theUniversity of Chicago before starting her career as a high school English teacher.[2][3]
In 1918, she married James Lyall Turnbull, just before his departure for Europe duringWorld War I. He returned, and they were married for 40 years and had one child, a daughter named Martha. The family moved toMaplewood, New Jersey in 1922, where she lived for the rest of her life.[4]
Turnbull had her first short story published byThe American Magazine in 1920, and published further short stories regularly until 1936, when she published her first novel,The Rolling Years.
Turnbull's earliest novels, sometimes called her "Westmoreland Novels", are heavily influenced by Scotch-Irish ethno-religious culture that dominated her upbringing in rural Western Pennsylvania.[3][6] These early novels have been identifies as offering subtle critiques of religious legalism, patriarchy, and industrial excesses.[3] Over the span of her six-decade writing career, Turnbull's later works were increasingly regarded as having old-fashioned morality, which she and others attributed it to a hopeful outlook on life.[7]
