Her obituary published in the Winnipeg Free Press on February 25, 2004:
MURIEL ADELINE WILTON (nee COULTHARD) It is with great sadness that the family announces that our dear mother, grandmother and great-grandmother passed away peacefully on Monday, February 23, 2004 at the Golden West Centennial Lodge, Winnipeg, at the age of 92. Muriel was born on May 24, 1911 in Saskatoon, SK, to parents Daniel Coulthard and Alda Maud Story who were both born in southern Manitoba. When Daniel died in 1915, his young widow and three daughters, Vera, Muriel and Lillian, returned to Manitoba. In 1918, Muriels sister, Lillian, with whom she was very close, died of diphtheria. When Muriel was 10, her mother remarried Clifford Lush and three more children were added to the family - Alvin, Eva and Raymond. Muriel married Walter Wilton on August 23, 1941 and they were married for almost 50 years when death separated them on December 19, 1990. Mom was petite, attractive and sweet - a wonderful wife and mother and an excellent homemaker. She did beautiful embroidery and knitting and was especially interested in designing her clothes and having a dressmaker make them for her. Dad always credited her for how well they managed as she could wisely stretch a dollar. Mom enjoyed playing bridge, dancing, was an avid reader and has been a lifelong member of Westminster United Church around which many friends and activities centred. Mom and Dad enjoyed many wonderful travel experiences throughout North America, Europe and New Zealand. Left to treasure her memory are her daughters, Lorrie Waugh (Bruce) and Joan Wilton; grandchildren, John Copsey, Robin Bonne (Michael Kilmury), David Brathwaite (Stephanie Kaye), Holly Arabsky (Ryan) and Dean Brathwaite; great-grandchildren, Matthew, Emma, Sara and Eric. Mom was predeceased by her husband Walter, her parents and her siblings. The family wishes to express their sincere gratitude to those very special people at Golden West Centennial Lodge who cared for our mother so lovingly over the past 13 years. Cremation has taken place and a celebration of Moms life will take place in April when all her family can be present. As an expression of sympathy, memorial donations may be made in Moms memory to the Alzheimers Society of Manitoba, 10-120 Donald St., Winnipeg, MB R3C 4G2.

Judging by the obituary, it is safe to assume that she had Alzheimers in her later years.
