Marmaduke ‘Duke’ Trebilcock
Marmaduke John “Duke” Trebilcock passed away on January 8th, 2026 at his home in Ontonagon, Michigan at the age of 86 with his family by his side.
Duke was born on November 12th, 1939 in Ontonagon, Michigan to Marmaduke A. and Bertha S. (White) Trebilcock. He attended school and lived all of his life in Ontonagon, with the exception of moving with his father in Pensacola, Florida for a short time in his teenage years. He married Nancy Wirkkala on July 20th, 1963 and made their home in Ontonagon and raised three daughters. They have been married for 62 years.
He worked on tug boats and his father’s shrimp boat while living in Pensacola Florida. He moved back to Ontonagon in 1960. He worked multiple other jobs before starting at the paper mill. He retired in 2005 after 43 years of employment.
He loved spending time with his family and friends.
He was very involved with his grandchildren in their activities including hockey, Boy Scouts, sports, and various others. Best remembered for his love of dancing; he never missed a song. He loved the great outdoors and enjoyed fishing, camping at Bob Lake, rides on his side by side, and driving his tractors and dune buggy that he built himself. He had lots of hobbies, but his favorites were building his model train set, wooden puzzles, making fishing lures, and was a jack of all trades. He was an avid Red Wings fan and rarely missed a game.
Duke is survived by his wife, Nancy Wirkkala Trebilcock; daughters Kelly (Greg) Litts of Ontonagon, Colleen (Thomas) Owens of Escanaba, and Charlotte (Matthew) Morgan of Ontonagon; grandchildren Rachel (Tyler) Rehak, Brandon (Kylee) Owens, Michael (Stacy) Morgan, Michele (Robert) Kallman, Nathaniel Morgan, and Ryan Wayman; great-grandchildren Bella Berger, Lachlan Owens, Connor Rehak, Gemma Rehak, Lyla Owens and baby on the way, Caleb Marmaduke Rehak, who is due to arrive around February 7th, 2026; sisters Meriea Carlton of Green Bay and Rosemary Smith of Green Bay; and other extended family.
Duke was preceded in death by his parents Marmaduke Allen Trebilcock and Bertha White Kullman, sister Mabel Morien, and brother Galen Doughty and other extended family.
The family would like to thank the Aspirus Hospice staff for their care, compassion and support. Thanks to the family and friends that supported us during this difficult time with your prayers and thoughtfulness. Lastly, thanks to Cane Funeral Home for their guidance through this difficult time.
A celebration of life will take place in the spring when all of the immediate family will be able to attend.
