Shirley Sue (Brown) Duncan, a beloved mother, grandmother, and the heart of her family, passed away peacefully at the age of 91, on January 10, 2026 in Heavener, Oklahoma. Shirley was born May 24, 1934 in Shady Point, Oklahoma to Grady and Hester (Holsted) Brown, leaving behind a legacy of love, service, and warmth that will never be forgotten. Shirley was a member of First Baptist Church, where she attended faithfully and raised her boys to know and love the Lord.

Family was the center of her life. She was deeply devoted to those she loved and found her greatest joy in caring for them. Her home was a place of comfort, laughter, and open doors—where no one ever left hungry. She was well-known for her ability to put together a full meal in a matter of minutes, always making sure that everyone who came through her door was fed and cared for.

She loved babysitting her grandchildren and spending time nurturing the next generation, creating memories that will be cherished forever. She found peace and happiness in gardening, delighting in watching things grow under her careful hands. She enjoyed musical movies, often humming along, and expressed her creativity through crocheting and quilting—each stitch a reflection of her patience and love.

Her cooking was legendary, her generosity unmatched, and her presence a steady comfort to all who knew her. She lived a life of quiet faithfulness, showing her love not only through words, but through actions—meals shared, blankets made, gardens tended, and time given freely.

She will be remembered as a devoted mother and grandmother whose life was a beautiful example of selfless love. Though she will be deeply missed, her spirit lives on in the family she nurtured and the traditions she passed down.
