He was a member of the 178th TAC, Ohio Air National Guard for six years. Jack really enjoyed his time spent volunteering at the Clark County Historical Society, St. Vincent DePaul, the Clifton Historical Society and the Hustead and Clifton Fire Departments. He was a long-time member of Saint Joseph’s Church where he loved singing in the choir. He stayed until he was no longer able to navigate the steps to the choir loft at the church. He then became a member of Saint Bernard’s Church and remained active up until his death. Jack was preceded in death by his parents, whom he adored, and his first wife of 32 years, Mary R.

He was overjoyed with his 13 grandchildren and 8 great grandchildren and loved spending time with them as much as possible. Jack had a life-long love of amateur radio and obtained his Operators/HAM license at the age of 15 and continued enjoying talking to people around the world up until his death. He had many local friends that are HAM operators as well. His call letters were W8JNK. He was also an avid American History buff and very proud of being inducted into the Sons of the American Revolution, Sons of the War of 1812 and Sons of the Confederacy.

He also enjoyed spending time with his grandson, Jon W. Kellough at his cabin in Jackson, Ohio where he taught Jon how to fish, hunt, shoot guns and ride a 4-wheeler. Later he enjoyed traveling with Barbara across the country and across the Atlantic. Wherever he traveled, their first stop was always a historic cemetery. Barbara says that she was always having her picture taken sitting on top of some head stone. He also enjoyed walking with his friends and his Thursday night dinner guys. Jack will be sadly missed.
