Shelly J. Williamson was born Martha Grace Shortt on July 31, 1945, in Rogersville, Hawkins County, Tennessee, to Nathaniel Delaney and Mildred Mae Tompson Shortt. Shelly has changed her name twice from Martha Grace Shortt to Martha Grace Montgomery in 1987 and again to Shelly Jean Williamson in 1993. Williamson was raised in Rogersville, where she was a student and a high school cheerleader. She entered Methodist Hospital School of Nursing in Memphis, Tennessee, on a scholarship in 1963. In 1965, she changed education paths. Williamson entered East Tennessee State University in Johnson City, Tennessee, where she studied Elementary Education until 1966. While studying at ETSU, she met Joe Gueron. They were married in 1966. Williamson again switched schools, and in 1969 she graduated from the University of Maryland in College Park with a B.A. in History. That same year, she and Joe decided to divorce.

Williamson lived and worked in New York State briefly before entering law school at the University of Maryland in 1970. She left law school after one semester because of illness. In 1974, she re-entered school, this time at the University of Tennessee in Knoxville. There, she earned an M.S. in library science.

In October 1976, Williamson met missionaries from The Church of Jesus Christ of Latter-day Saints. She became a member of the Church on January 1, 1977. Since her baptism, Williamson has been a devout Latter-day Saint who allows her deep faith in God to influence all aspects of her life.

Williamson worked as a librarian in Tennessee elementary schools and public libraries until 1985, when she left to serve a mission for The Church of Jesus Christ of Latter-day Saints. She served in the Anaheim California Mission from April 1985 to November 1985 and in the Salt Lake City North Mission from November 1985 to February 1986.

After her mission, Williamson held a variety of jobs in northern Utah including: cataloger at Dugway Proving Ground in Tooele, Utah and in the Historical Department of The Church of Jesus Christ of Latter-day Saints in Salt Lake City, Utah; adjunct faculty at Salt Lake Community College in Salt Lake City, Utah; office manager at BAR/BRI of Utah East Salt Lake City, Utah; independent study course materials specialist at the University of Utah Bookstore in Salt Lake City, Utah; department secretary for Army ROTC at the University of Utah in Salt Lake City, Utah; vault coordinator at LDS Motion Picture Studio in Provo, Utah; and Section 8 housing specialist at the Housing Authority of Utah County in Provo, Utah.
