Sue Ann Duncan

Sue Ann Duncan, beloved wife, mother, grandmother, great-grandmother, and friend, passed peacefully into the arms of our Lord and Savior on February 4, 2025. Sue was surrounded by her loving family. She was born on February 27, 1946, in Casper, Wyoming, to Melvin and Pearl McNatt, joining her two older sisters, Melva and Pauline. Sue spent nearly her entire life in the Midwest and Edgerton areas, where she attended school throughout her childhood.

In April 1964, Sue was blessed with the birth of her first son, Ronald (Jake) McGowen, and in November 1974, she welcomed her second son, Robert Duncan. On February 19, 1983, she married the love of her life and soulmate, Michael Duncan, in Miles City, Montana. Through their marriage, Mike and Sue blended their families, adding two beautiful daughters, Angie and Sarese, making their family complete.

Sue worked in the oil field as a pumper in the early 1980s and later as a secretary for various oil field companies in the Midwest/Edgerton area. However, her true calling and passion in life was being a homemaker, a devoted wife, a wonderful mother, and an extraordinary grandmother.

Sue loved spending time in the Big Horn Mountains, fishing, riding ATV’s, picking choke cherries for jelly, and sneaking down to Buffalo or Tensleep for an ice cream cone. She loved pigs. She even had her own pet pig named Schooner! She was an avid collector of cookie jars, and she sewed many costumes. She loved to knit a nice sweater for her boys.

Sue took immense pride in each new addition to the family. She was blessed with eight grandchildren: Keely, Christopher, Kagen, Ben, Mia, Scarlett, Jocelyn, and Logan. She cherished teaching them to play Blitz, Rummy, Go Fish, and many other games, as well as sharing her love of baking sugar cookies and decorating them. Sue always ensured her grandchildren were entertained. They were always busy making homemade playdough and doing fun activities that created many cherished memories.

The 2000s brought even more joy with the arrival of five great-grandsons: Robert, Hayden, Conner, Dakota, and Bo, as well as a great-granddaughter, Addison. Sue was always eager to spend time with them, whether for an afternoon visit or an overnight stay. The most recent additions to her ever-growing family were her three precious great-great-granddaughters. She lovingly sent holiday cards filled with warmth and love from Grandma Sue and Grandpa Mike for every occasion, from Valentine’s Day to Christmas.

Sue is survived by her devoted husband of 42 years, Michael Duncan of Casper, WY; her children, Ronald (Judy)McGowen of Midwest, WY; Robert (Misty) Duncan of Douglas, WY; Angie Dorner of Gillette, WY; and Sarese (Troy) Svihl of Muskego, WI. She also leaves behind her grandchildren and great grandchildren: Keely (Josh) James of Douglas, WY; Christopher McGowen of Casper, WY; Kagen McGowen of Casper, WY; Hayden (Alexis) Nelson of Casper, WY; Conner Nelson of Glenrock, WY; Dakota James of Casper, WY; Bo James of Douglas, WY; Robert (Vicky) Lanier of Casper, WY; Ben, Mia, Scarlett Svihl of Muskego, WI; Jocelyn Ruhland of Aacworth, GA; Addison Mcgowen of Douglas, Wy; and Logan McGonigle of Newport News, VA; her three Great, Great Granddaughters: Shevelle, Bentlee and Tenslee Jo, along with numerous nieces, nephews, cousins, and dear friends.

She was welcomed into heaven by her parents, Melvin and Pearl McNatt; her sisters, Melva Malson and Pauline Wilson; and two half-brothers Gus and Howard Holmberg; a grandson Kyle McGowen and her dearest friend Patsy Wood.

Sue will be deeply missed by all who knew and loved her. Her kindness, warmth, and unwavering love for her family will forever be cherished in the hearts of those she leaves behind.

A Celebration of Life will take place in Casper, WY, on June 2025. The location will be announced at a later date.
