Clayton John Thomas Knowles, age 90, passed away on Sat, Aug 20, 2022, at his home in Twin Lakes, MI. Clayton was born on May 20, 1932, to his parents, Harold and Christine (Oosting) Knowles in Muskegon, MI. He graduated from Muskegon High School and went on to work as a supervisor at Westran Foundry for 23 years and then as a machine operator for 27 years at SD Warren Paper Mill. On Mar 10, 1951, he married the former Millie Mae Palmer, and they shared 56 wonderful years together before she preceded him in death in 2008. Clayton was an avid outdoorsman, he travelled all over the country on hunting and fishing trips. He enjoyed listening to old country music, and he loved the four purebred poodles that he had over the years, all of whom were named Lacy. He was a hard worker and a fan of Ford vehicles: only Fords were allowed to park in his driveway, all other vehicles had to park in the street. Clayton will be lovingly remembered by his children: Cindy Flowers, Jack (Lisa) Knowles, and Charles Knowles; 13 grandchildren and many great grandchildren; two siblings: Sandra Lewis and Harold (Heidi) Knowles; an adopted son, Dave Brooks; and special friends, Orville and Delores Truax, who went on multiple special trips with Clayton after their retirements. Clayton was preceded in death by his parents, Harold and Christine Knowles; wife, Millie Mae Knowles; and son, Michael Knowles. Per his wishes, no public service will be held for Clayton. In lieu of flowers, donations in his memory can be made out to Kindred Hospice. Arrangements by The Sytsema Chapel of Sytsema Funeral & Cremation Services, 737 E. Apple Ave, Muskegon, MI 49442.
