Jeanette lived a life rooted in faith, community, and service. As a devoted member of St. Mary’s Catholic Church and the Altar Sodality, her faith was a central part of her life.

A member of the Clinton County Farm Bureau, Jeanette fully embraced farm life whether she was helping her neighbors or confidently driving a tractor.

Creative and full of life, she loved quilting, painting, and going dancing. Above all, Jeanette loved her family and found immense joy in supporting and helping her beloved grandson, Kyle.
