Stacey Diane Duncan

Stacey Diane Duncan, 83, of Arnold, Missouri, passed away peacefully on August 13, 2026, in Sedalia, Missouri. She was born on September 13, 1942, and is preceded in death by her parents, Claude H. Allen and Virginia D. Allen; her brothers, Claude D. Allen and Jeffrey Allen; and her brothers-in-law, Marshall Swalley and Glenn Reichmann.

Stacey will be lovingly remembered by her son, Timothy Riley; her sisters, Dana Swalley and Cate Reichmann; her sister-in-law, Jane Allen; as well as numerous nieces, nephews, cousins, and dear friends.

She was born in East St. Louis, Illinois and spent much of her adult life in Arnold, Missouri, where she built a beautiful home and a life surrounded by the things she loved.

Stacey was a woman of creativity, faith and appreciation for beauty. One of her greatest passions was painting. What began as a love of art and a pursuit of learning, eventually became an opportunity to teach others. During the 1970’s and 1980’s, Stacey taught painting classes at an art supply and painting store, sharing the skills and techniques she had first learned as a student with others, who also shared her love of painting. She took great pride and joy in helping people discover their own creativity and bring out the best in themselves.

Her faith was an important part of Stacey’s life. She was an avid member of Oasis Church in Arnold, Missouri, which became much more than a place of worship for her. The people there were her church family, and she deeply valued the friendships, love and sense of community she found among them.

Stacey took great pride in decorating her home, creating beautiful and welcoming surroundings that reflected her unique style and appreciation for the finer details in life. She enjoyed antiques, antique shopping, and visiting flea markets, always appreciating the stories and unique qualities behind the treasures she discovered.

She will be deeply missed and lovingly remembered by all who had the privilege of knowing her.

Stacey will be laid to rest at Lake View Memorial Gardens in Fairview Heights, Illinois.
