William John Hartwick Jr., 68, passed away March 9, 2020, at Oak Park Place in Burlington.

William was born Sept. 24, 1952, to the late William Sr. and Florence Hartwick in Hicksville, New York. He lived in New York until moving to Wisconsin in 1970.

On Feb. 5, 1982, William married the love of his life Kathleen Bonczkowski. Not long after William began his career at U.S. Bank, working there until he retired in 2013.

He was an avid Packers fan but was most passionate about traveling. Kathleen and William shared many adventures around the world from close-to-home places like Green Bay and St. Germain all the way to L.A., Alaska, Paris, Milan, and many more. Many family vacations up to Northern Wisconsin were some of William’s fondest memories.

William will be dearly missed by his loving wife Kathleen; his stepchildren, Jay (Alicia) Bonczkowski and Amy Atkinson; his step grandchildren Jaime Bonczkowski, Shannon (Shane) Harris, and Courtney Atkinson, as well as step-great grandchildren Camden, Cambrie, and Camberlin Harris.
