Betty was born the last of five daughters on April 5, 1948, in San Angelo, Texas to John Burress Box and Mary Ella (Pool) Box. She attended San Angelo State College and graduated from Baylor University. She moved to San Antonio to teach school in the Northeast I.S.D. While in San Antonio, she became a member of Trinity Baptist Church where she met her husband of more than 43 years, Davis “Dave” Delyle Morgan. They moved to Devine in 1972 and raised four children there: Davene Morgan of Dallas, Lindsey Randow (Joshua) of San Marcos, Davis Morgan (Tiffany) of Colorado Springs, Colorado, and Courtney Sharp (Randy) of Bastrop.
Betty taught school for more than thirty-five years, most of which were spent teaching first grade at John J. Ciavarra Elementary School in Devine. She loved her Savior Jesus Christ, children, and education and positively impacted generations both in her job and through her decades of teaching Sunday school at church. She also helped cook thousands of meals with the Texas Baptist Men Disaster Relief Services mass feeding unit and served on the Emergency Services District board for Devine.
