On October 31, 1964, Kathy married Hugh “Butch” Cooper at St. Mary’s Cathedral. Together, they made their home in Cheyenne, where they raised their family.

She treasured being part of their lives, hearing about what they were doing, and watching them grow into the people they became. They could always count on Grammy for encouragement, wisdom, lively conversation, and her unmistakable sense of humor. Known for her quick wit and thoughtful observations, Kathy had a way of making time spent together memorable. Her strength, loyalty, and deep love for her family will live on through the many memories they shared and the lasting influence she had on those she loved.
