Mary Louise Thornton was born in Louisa County, Virginia, in a home that had been in the family for many generations called Cuckoo House on June 12, 1891. She was the one of four children of William Percy Thornton and Elizabeth Pendleton. The family moved to Salisbury, North Carolina, and then Atlanta, Georgia.

Thornton graduated from the Atlanta Girls High School. and the Carnegie Library School of Atlanta (later affiliated with Emory University). She was a librarian at the University of Georgia from 1913 to 1917.

Weeks' collection of North Caroliniana, which added an additional 10,000 items. Though she would have periodic offers for higher paying jobs, she chose to remain at the North Carolina Collection for decades. She also earned two additional degrees from the University of North Carolina during her time as an employee. Her thesis for her M.A. in History was entitled "Public printing in North Carolina from 1749 to 1815."

During her time as the curator, the North Carolina Collection added donations from John Sprunt Hill and Thomas Wolfe's family. Additionally, Thornton was an author, having written two books, Official Publications of the Colony and State of North Carolina, 1749–1939 and A Bibliography of North Carolina, 1589–1956. She also wrote numerous journal articles.

Thornton continued at the university until 1958. She died at the age of 82 and is buried in the Chapel Hill Cemetery.
