Diane Mckain
March 19, 1955 — October 2, 2026
Diane Mckain, a beloved mother, grandmother, great-grandmother, and cherished friend, passed away unexpectedly at Butler Memorial Hospital. Born on March 19, 1955, in Butler, Pennsylvania, Diane was a beacon of warmth and kindness to all who had the privilege of knowing her. Her life was a testament to love, resilience, and the joy of simple pleasures.
Diane was the loving daughter of Jane Viola Steffy and William Edward Steffy Sr. was predeceased by both of her parents, a son,her two brothers, her sister, and her husband, David A. Mckain. Despite these profound losses, Diane's spirit remained unbroken. Her heart was a sanctuary of love and laughter, which she generously shared with her surviving family: her devoted long-term fiancée Tim Cook, her son Dave Mckain, her three brothers Ronald, Dan, and Terry Steffy, all residing in Butler. She also leaves behind a legacy of seven grandchildren and five great-grandchildren, who brought immeasurable joy to her life.
Diane had a zest for life that was evident in her many hobbies and interests. She found joy in the camaraderie of a lively game of bingo, the quiet satisfaction of completing intricate puzzles, and the unconditional love of her beloved dogs. Above all, Diane cherished her family, always prioritizing time spent with them, creating memories that they will hold dear forever.
Her passing leaves a void that will never be filled, but her legacy will continue to live on in the hearts of all who knew her. Her family finds comfort in the countless memories of laughter and love that she leaves behind.
In honor of Diane's memory, the family suggests that those who wish to make a donation consider contributing to a charity of their choice, reflecting Diane's spirit of generosity and compassion.
As we say goodbye to Diane, we remember a life lived with grace and a heart full of love. She will be profoundly missed and forever cherished.
