Katherine Renee Kirby Miffleton of Plano, Texas passed away peacefully on September 28, 2026, at age 73. Despite the challenges of her illness, she remained concerned for others and encouraged her family not to “think negatively.” Katherine was born March 12, 1953, in Odessa, Texas, to Sam Hildred Kirby and Charline (Knight) Kirby.
She was a proud alumna of The University of Texas, where she earned her bachelor’s degree in business. Katherine went on to build a career in the finance industry, dedicating more than 20 years to her profession before turning much of her time and attention towards her family, community, and the causes she held close to her heart.
Katherine had a deep and enduring love for animals, particularly cats and dogs. She was actively involved with the Humane Society and contributed her time to its legislative efforts, advocating for the protection and welfare of homeless animals. She also generously funded several charities dedicated to rescuing and finding loving homes for animals in need. Her compassion for animals was an important part of her life and a reflection of her caring heart.
In 2008, Katherine married Neldon Miffleton. Together, they shared 18 precious years filled with love, companionship, friendship, travel, and countless cherished memories.
Katherine was a woman of strong character and a direct, determined personality, balanced by a deeply caring heart. She was a leader in many local community groups and gave generously of her time and energy to the people and causes around her. She enjoyed spending time with friends, traveling, and, above all, being with her family.
Katherine will be remembered as a loving wife, mother, sister, aunt, and friend. Her strength, generosity, devotion, and compassion touched many lives. She will be missed dearly by all who knew and loved her.
Her memory will live on in the hearts of her family, friends, and in the many lives of both human and animals that she helped make better.
Katherine is survived by her beloved husband, Neldon Miffleton of Plano, Texas; daughter, Stacy Whiteside; two nephews; two nieces; friend and family adopted daughter, Melissa Traut; numerous other loving family and friends.
