Peggy J. Duncan, age 90 of Seguin, Texas, passed away on August 21, 2025.  Peggy was born on March 30, 1935 in DeWitt, County, Texas to Gertrude E. (Mott) and Lemuel Albert Duncan.

Peggy was a lifetime friend and employee of the Cone Family and Cone Bioproducts, joining Bob Cone in Seguin when the new Guadalupe Valley Hospital was opened in the 1960's.  For some time, Peggy had been visually impaired, but her quiet determination and fierce independence never stopped her, often walking to work to get the job done.  She began her career in STEM with Cone Bioproducts when few women worked in that field.

She was an active member of First Baptist Church in Seguin where she was a member of the Joy Class.  She enjoyed tracing her family roots all the way back to the European Continent and always had a love for pets.

Peggy is preceded in death by her parents and her brother, Albert Duncan, Jr.

Survivors include beloved friends, The Cone Family and the Cone Bioproducts employees; her beloved cousin, Nona Kay Scales and her family; her loving caregiver, Louisa Allmand; and her beloved dog, Robin and cat, Mr. Boots who both preceded her in death.

Funeral service will be held on Wednesday, August 27, 2025 at 10 a.m. at First Baptist Church with the Reverend Dr. Brice Mandaville officiating. A reception will follow.

Graveside services and interment will follow at 2 p.m. in the County Line Cemetery in DeWitt County near Cuero.
