Kathy was born on December 30, 1938 in Los Angeles, California to Gene and Molly (Brentano) Iglehart. She graduated from Glenbard High School in Glen Ellyn, IL, in 1956 and later graduated from the Chicago Art Institute. She was a commercial artist for many years before becoming a full-time homemaker. On June 5, 1965, she married Jim Gilbert in Overland Park, Kansas. They raised 2 sons, Jimmy and Gene.

Kathy had a lifelong passion for arts and crafts. She created countless boy scout awards for her sons' troops and aided in many projects. She enjoyed still life painting and turned numerous rocks into painted owl paper weights. In her later years, she took great pride in welcoming all new extended family members with handmade Christmas stockings.

She is survived by her husband Jim, her children Jimmy and Gene, her grandson London, her sister Emily, and her brother Rick.

Kathy is preceded in death by her father, Gene, and her mother, Molly.
