Ruth Evelyn Bunch was born in Town of St. Stephen, SC in February 1901. Her parents were Edward and Mary Bunch.

By the fall of 1918, Bunch had moved to Charleston. She enlisted as a Landsman, Yeoman (F), U.S. Naval Reserve Force in September; it's possible that she lied about her age, because the "The Official Roster of South Carolina Soldiers, Sailors and Marines in the World War" claims she was born in 1899. Bunch was stationed at the Navy Yard in Charleston until Armistice Day.

Bunch was discharged as a Yeoman (F) 3rd class in June 1920. Her occupation is listed as "civil service stenographer" on the 1920 census, and she worked as a stenographer at the Port Terminal
through at least 1921.

By 1930, Bunch was married to accountant Harry Walker and living in Atlanta. Harry Walker had also been in the service, a sergeant in the Quartermaster Corps. Their time in Atlanta must have been brief, because they were living in the Charleston area again by 1935 and through Harry's death in 1967.

Bunch lived a long life, dying in Florida in 1991.
