Mary Sue (Brewster) Ellenberger-Stambaugh

September 26, 1935 — March 7, 2024

Mary Sue (Brewster) Ellenberger Stambaugh, beloved wife, mother, and Gigi, gracefully departed this world on March 7, 2024, to embrace her heavenly wings. Born on September 26, 1935, in Atchison, Kansas, to Agnes Eastly Brewster and Lee McGregor Brewster.   Mary's life was a testament to love, kindness, and selflessness.

Mary will lie in state for viewing on Monday, March 11, 2024, from 10am to 6pm at Schooler Funeral Home, 4100 S. Georgia. Funeral Serivces will be held on Tuesday, March 12, at 10:00 am in the Funeral Home’s Brentwood Chapel, with Jim McKee of Hillside Christian Church presiding. The family will briefly receive guests at the funeral home following the service before the committal service where Mary will be laid to rest at Llano Cemetery.

Mary graduated from El Paso High in 1954 and furthered her education by studying Oil and Gas Law at WT State University, paving the way for her career as a Senior Title Analyst with Santa Fe Energy. She dedicated over three decades of her life to her work before retiring in 1991, leaving behind a legacy of excellence and professionalism.

Mary found her lifelong companion in Bill Stambaugh, with whom she exchanged vows on February 13, 1960, in Alamogordo, New Mexico. Together, they nurtured a beautiful family, which expanded to six with the addition of Russell, Stanley, Sondra Stambaugh, and James (Rick) Ellenberger. Their family became complete on September 8 with the arrival of their baby girl, Julie Daily.

Mary's profound love for God, music, horses, friends, and dance was evident in every aspect of her life. She couldn't resist the pull of a captivating tune, always ready to move to the rhythm, no matter where she was. Her passion for dance brought joy to those around her and created cherished memories that will endure.

Mary had a special talent for crafting heartfelt poems. Her words touched the hearts of those fortunate enough to read them, leaving a lasting impression and inspiring others with their depth and sincerity. Her creative spirit and love enriched the lives of everyone she encountered.

Mary's true passion was her unwavering dedication to her family. She embodied love and compassion in every aspect of her life, always prioritizing the well-being and happiness of her loved ones above all else. Her commitment extended beyond mere words, as she selflessly cared for her ailing husband, mother, and father in the comfort of her own home all at once, giving of herself to the point of self-sacrifice. Her boundless love and sacrifice are a testament to the depth of her character and the strength of her spirit.

After enduring life's challenges, Mary was blessed to find solace and companionship in Harold Byford. She frequently expressed that all she required was a hand to hold, and Harold provided the comfort and support she needed in her later years. Their relationship was a beautiful testament to Mary's resilience and capacity for love, illuminating the lives of those fortunate enough to witness their bond with light and warmth.

Mary Sue Stambaugh is preceded in death by her beloved husband, Bill Stambaugh, her son, Rick Ellenberger, her great-granddaughter, MarayJa Daily, and two stepchildren, Russell and Sondra Stambaugh and her last love Harold Byford.

Mary is survived by her daughter, Julie Daily, and Lee Sumner of Amarillo, along with grandchildren Candace, Kizer, Rachael, Kelley, Michelle, and Michael. Additionally, she is survived by her great-grandchildren Skyler Harper, Sophia, and Michael Daily of Amarillo. Mary's extended family further blessed her with many more grandchildren and great-grandchildren, whose love and presence brought her immense joy and fulfillment throughout her life.

In addition to her human family, Mary is survived by her beloved fur babies, Jax and Doc, whose companionship brought her endless joy and comfort.  Their presence was a source of warmth and solace, adding an extra layer of love to Mary's home.

In lieu of flowers, the family kindly requests donations to be made to the Children's Miracle Network in remembrance of MarayJa Daily, Mary’s beloved great-granddaughter who passed away just four days after turning 10 years old.

Your contributions will honor MarayJa's memory and continue Mary's legacy of compassion and care for others.
