Barbara was born on September 28, 1948, to parents, Robert and Vera (nee Lupac) Kutchan, in Chicago, IL. As a family, they relocated to Brookfield, IL, where she made and created memories with her lifelong best friend, Joanie McAvoy. She graduated from Riverside-Brookfield High School in 1966.

She also served as the Librarian for the Bolingbrook Chorus and the Tri-Lakes Community Singers.
She spent most of her life caring for her family and homes. She also enjoyed part-time work for the Naperville Sun and the Isabel Bloom Store in downtown Naperville. She will be remembered for her attention to detail and love of music.
