Kenneth James Thomsen

October 4, 1943 ~ June 8, 2022 (age 78)


Kenneth James Thomsen passed away peacefully in his home on June 8th, 2022 surrounded by his loving family. He was born October 4th, 1943 in Livermore California, to Sigurd and Ruth Thomsen. Ken was a kind, loving and gentle man of few words, but his presence was grand. He will be missed by all who knew and loved him.

His first home was on the outskirts of Dublin surrounded by many other Danish farming families. In 1949 the family moved to Pleasanton on Santa Rita Road where his agricultural career together with his father and brothers really began. They grew tomatoes, cucumbers, sugar beets and wheat. Farming wasn’t easy in those days! He started working in the fields as soon as he returned home from school. But it was worth the sweat, because the day always concluded with a hearty, delicious home-cooked meal by his mother.

The house on the property was restored by the city of Pleasanton and is now called the Century House. Development was crowding out the farmers in the area so the family moved to the south of Tracy in 1966. Ken managed Thomsen Farms and introduced a couple of new crops - lima beans and almonds. He followed his father’s footsteps as a relentlessly dedicated farmer.

Ken met his wife, Paulette on a blind date. They tried to secretly elope in 1964, but he had to call his parents for permission because he wasn’t of age. They were married for 55 years. Ken was a family man! In fact, he only enjoyed traveling if his family was in tow, especially trips to Ohio to visit the McCune side of the family. He was his kids’ hero with his big strong hands and loving heart. Their first child, Kimberly, stayed by his side the last 3 years as his health declined. The family is forever grateful for her dedication.

He enjoyed farm talk at the local coffee shop with fellow farmers. Farm talk being the comparison of whose crop was bigger and better. He was a member of the Danish Society of Dania in Livermore, the Elks Lodge, and the Model “A” group of San Jose.

Ken is survived by his three children Kimberly Guillen, Jamie, Kristin and Kristin’s wife Tracy. As well as eight grandchildren, Robert Ontiveros and his wife Michaela, Wyatt Henricus, Larissa Riches and her husband Alan, Ty Guillen, Taylor, Krista, Timothy and Kendyl Thomsen. And four great grandchildren, Aubrey, JJ, and Paul Ontiveros and Westyn Riches. He is also survived by his sister Kathy Thomsen of Tracy, brother Allen Thomsen and his wife Mary of Madera, brother-in-law Mike McCune of Tracy, Pat McCune & his wife of Mesa, Arizona, sister-in laws LouAnn McCune and her husband Lowell of Idaho and Carolyn Bortz of Livermore. He is preceded in death by his wife of 55 years, Paulette, parents Sigurd and Ruth Thomsen, brothers Thomas and Gerry Thomsen, and son-in-law Bob Henricus.
