Nancy Karen Seibert

Nancy Karen Geisendorff Seibert, lovingly known as “Nan-Nan,” passed away peacefully at Dogwood Trails Nursing Home in Woodville, TX on Monday, November 3, 2025 at the age of 77.

Nancy was born on April 5, 1948, in Dayton, Texas, to Edgar and Marie Geisendorff, who preceded her in death. She was also preceded in death by her beloved husbands  - Junius Dupre, with whom she shared 27 wonderful years; Ray Gieseki, her husband of 6 years; and Corky Seibert, her husband of 5 years - each of whom she nurtured and cared for until their deaths. God used her as a witness to bring each of them to know Jesus as their savior. 

Nancy is survived by her son, Bryan Joseph Dupre, and her two precious grandchildren, Embry Marie and Reagan Joseph Dupre. She is also survived by her sister, Sandra Geisendorff Keys, and brother-in-law, Harold Lee Keys; her brothers, Edgar Geisendorff and sister-in-law Laura, and Rick Geisendorff.

She was very close with her many cousins and loved and adored her nieces and nephews as if they were her own children - Michael, Ed, Belinda, Rick Jr., Cindy, Chris, Darrell, and Amanda - along with her 27 great- and great-great-nieces and nephews who brought her endless joy.

Nancy was a loving and devoted wife, mother, sister, aunt, cousin and friend. If you ever needed a good laugh, a kind word, or a warm hug, she was always there. Her sense of humor and generous heart made everyone feel loved and welcome.

Gifted with a remarkable eye for beauty and creativity, Nancy was known for her talent in decorating and her skillful handwork -  some examples of her talent are displayed today. A graduate of beauty school, she had a lifelong passion for hair, makeup, and nails, and was equally known for her quick wit and sense of humor. But above all, she will be remembered for her generosity, her kind heart, and her endearing inability to keep a Christmas gift a secret.

Nancy loved music and was often heard singing the songs and playful tunes from her youth. Her joyful spirit filled every room she entered.

More than anything, Nancy loved her family and the Lord. They were the center of her life, and she made sure they always knew how deeply they were loved. Her laughter, creativity, and generous spirit will be missed beyond measure and remembered always by all who were blessed to know her.
