Jon R. Wilsnack, age 65 of Green Lake/Markesan, passed away unexpectedly at home on Sunday, November 1, 2020.

Jon was born in Waupun on March 20, 1955, the son of Wilton and Ruanne (Lueptow) Wilsnack. Jon was a graduate of Markesan High School, UW-Oshkosh, & William Mitchell College of Law. Upon graduating from law school, Jon chose to come back to Markesan to work as an attorney. He had grown up there and wanted to be able to help the community and the people he cared so much about. On October 27, 1990, he was united in marriage to Kathryn Kuehn at Zion Lutheran Church, Fairwater. They had one daughter, Alyssa, who was his pride and joy. Jon loved sharing his passion for golfing and the Packers with her. He enjoyed spending time with his collies, of which he has had five, and relaxing at his home in Florida, where he hoped to retire someday.  Jon made an impact on so many people and will be greatly missed
