Mark Duffy Obituary

Published by Legacy Remembers on Sep. 10, 2025.
Mark Steven Duffy, 69, of Cottage Grove, passed away peacefully at his home at Drumlin Reserve on September 10, 2025, from congestive heart failure. He was born on October 28, 1955, to Richard Paul Duffy and Verdeen Marie (Duffy) Rock.

Mark loved the outdoors, especially fishing with his brothers and hunting with his father. He enjoyed playing football in high school, traveling on car trips, and sharing meals with family at Culver's and Perkins. He treasured time with his siblings and the care of his sister Patricia in his later years.

He is survived by his siblings David Patrick Duffy (Gale), Gerald Francis Duffy (Kathy), Patricia Marie Sternad (John), Daniel Paul Duffy (Kristin), and Jacqueline Ann Bacon (Kevin). He was preceded in death by his parents Richard Paul Duffy and Verdeen Marie (Duffy) Rock.

Mark will be laid to rest at Sacred Heart Catholic Cemetery in Sun Prairie near his father. A private celebration of life will be held at a future date.
