Nancy Howard Muessig O'Connor, an inspiring woman of warmth, resilience and love passed away on November 7, 2026 born on March 31,1940 in Maryville, MO. Nancy led a life filled with love, laughter and an unwavering commitment to her family and community. She was the cherished daughter of the late William Earl and Helen Howard and was predeceased by her first husband, Tom Muessig, with whom she shared nearly twelve beautiful years. Her siblings, Mary Ellen Junk, Paul Howard, Raymond Howard, Dorothy Malchow, Arthur Howard, Kenneth Howard, Dolores List and Ronald Howard also welcomed her with open arms into eternal rest along with her granddaughter Maggie Fangman and daughter-in-law Michelle O'Connor.
Nancy's life was a testament to the power of love and resilience. After the loss of her first husband, she found love again and married Mike O'Connor, her devoted husband of 41 years, on August 16, 1985. Together, they created a blended family filled with joy and laughter. Nancy's legacy lives on through her children: Lisa (Matt) Walter, Amy (Tom) Fangman, Sarah (Mike)Book, Kevin (Sherrie) O'Connor, Katy Whalen, Mary Ann Gensler, Laura (Kerry) Denison, Tim O'Connor, Damian O'Connor, Tom (Leigh) O'Connor and Rita (Brian) MacGee. Her heart and home were always full, blessed with 31 grandchildren and 30 great grandchildren each a testament to her enduring spirit and love.
An alumna of Leavenworth High School class of 1958, and Saint Mary's College in Leavenworth, KS, Nancy embarked on a professional journey that saw her grace several esteemed organizations, including Kansas City Life Insurance company First National Bank, Shawnee Mission Northwest High School, Colonial Savings and Loan, and Kimberly Nursing. With entrepreneurial spirit she also owned and operated two Formu-3 Weight Loss Centers.
Nancy's life was enriched by her faith and community service. She was a devoted Catholic and longtime member of Sacred Heart of Jesus parish in Shawnee, KS. Her early years were marked by active participation in Jaycee Jaynes working alongside her husband Tom to serve the community. Her compassion and empathy extended to Beginning Experience where she transitioned from participant to team leader offering support to those separated, divorced or widowed experiencing grief and loss.
Music was a profound part of Nancy's soul. Her love for singing shone brightly as she harmonized with Sweet Adelines alongside her sister and continued to sing for forty-one years with her beloved husband Mike. Her passion for music only rivaled her love for family, cherishing every moment spent at her children's and grandchildren's events, whether on the field, court, stage or at school. The highlight for her every year was the family tradition of participating in the KC Saint Patrick's Day parade followed by a large gathering of friends and family.
Nancy was known for her loving and calm nature, with one exception-- when the Kansas City Chiefs took the field her spirited loyalty emerged in full force. Her kindness and empathy left an indelible mark on all who knew her, touching countless lives with her generous heart and unwavering support. In addition to her eleven children, there are many who considered her their honorary mother.
She leaves behind a legacy of love kindness and strength that will continue to inspire those fortunate enough to have known her. If you would like to donate in Nancy’s honor, you may do so to Catholic Community Health @ Catholiccommunityhealth.org
