Gloria Mersiosky

June 16, 1942 – December 23, 2025

Gloria Jean Mersiosky passed away in Horseshoe Bay, Texas, on December 23, 2025. Her final hours were spent surrounded and comforted by her loving family. God’s grace allowed her to spend Christmas with her waiting husband, Ed, and her Lord and Savior, Jesus Christ.

Gloria was a devoted wife, mother, grandmother, and great-grandmother. Gloria’s life was a perfect reflection of what she valued most – serving her family and friends and living out her faith in Christ.

Gloria was a lifelong member of the Lutheran Church. Gloria worshipped at Zion Lutheran Church in Walburg and was a founding member of Faith Lutheran Church in Georgetown. Gloria’s greatest passion was spending time with her late husband, Ed, and their children, Mike and Susan. Her legacy is one of devotion to those she loved, including her church and her close friends.

Gloria was born to Elbert and Anita Keilberg in Muleshoe, Texas, on June 16, 1942. Gloria always giggled when calling herself a native “Jenny Slipper.” Gloria had one brother, Aubrey. Very early in Gloria’s life, the family moved to Pettus, Texas, and after a few short years, they relocated to Corpus Christi. Gloria met Ed Mersiosky in Corpus Christi, and in 1961 they were married at Mount Olive Lutheran Church. In 1966, Gloria and Ed moved to Kingsville, Texas, to raise their two young children, Michael and Susan.

In 1977, Ed sold the Borden Milk business, and they opened their first Sonic Drive-In on Austin Avenue in Georgetown. The young Mersiosky family moved from Kingsville to Georgetown in 1967. Today, the Sonic franchise that Ed, Gloria, and Mike built continues to expand and is still operated by their son, Mike, and grandson, Brent Mersiosky.

With the help of his son, Mike, Ed was able to enjoy an early retirement from Sonic. During the 1990s, Ed launched a successful second career as a developer and homebuilder in the Riverview Estates Subdivision. Gloria quickly became the dynamic duo’s designer, and many attractive homes in the Riverview neighborhood still display her skilled floor plans and blending of material and color selections. Gloria was a talented designer/builder and loved building new homes, including their final Georgetown home, a Lake LBJ retreat, and their beloved summer home in Creede, Colorado.

In 1987, Ed and Gloria helped their daughter, Susan, purchase a small women’s clothing store in Salado, Texas. Susan and Gloria worked tirelessly together to take that small initial investment and build “Susan Marie’s” into one of the most successful and well-known boutiques in Central Texas. Five times a year, for 20 years, Gloria and Susan spent a week together at the Dallas Market Center during each buying season. Gloria and Susan were never short of ideas to expand or remodel the store, change displays, or otherwise improve Susan Marie’s. Ed and Susan’s husband, Steve, were enlisted to help complete their vision. Gloria was always on hand to help Susan when the store was short-handed or during a busy holiday season.

Gloria loved to cook for family and friends, and the dinner table was just another way that she showed her love for others.

Gloria loved to travel, and for more than 25 years, she and Ed made the yearly summer trek to their “Happy Place,” Creede, Colorado, to escape the heat. In Creede, Gloria was able to grow wonderful friendships, travel the backcountry, become a talented potter, and develop her amazing gift of painting in a wide variety of mediums.

It should be clear by now to the reader that Gloria’s life was never about her being the center of attention or seeking praise for herself. Gloria spent her life as a perfect example of a willing servant, always supporting, always helping, always serving others—whether it was her husband, her children, her church, or her community.

The family is very thankful and appreciative of Gloria’s loving caregivers, Maritza, Alexandra, Kimberly, and Ariel.

Gloria is survived by her son, Mike Mersiosky and wife, Robbie; daughter, Susan Richmond and husband, Steven; grandchildren, Brent Mersiosky and wife, Amanda; Regan Mersiosky; and Christine Mersiosky; great-grandchildren, Daniel, Audrey, and Carly Mersiosky; and numerous nieces and nephews.

She is preceded in death by her husband, Ed; her parents, Elbert and Anita Keilberg; and her brother, Aubrey Keilberg.

A graveside service for family will be held at the Zion Lutheran Cemetery.

In lieu of flowers, memorials may be sent to Pamela J. Hight Scholarship Fund at Zion Lutheran School or The Caring Place, Georgetown, Texas.
