Wilmer W. "Bill" Siebert, age 90, longtime town of Gibson resident, passed away peacefully early Sunday morning, January 25, 2026 with his family at his side.

Bill was born in the town of Morrison, Brown County, on December 7, 1935 to Edmund and Mathilda (Rose) Siebert. He attended Wayside Lutheran School and Reedsville High School. He then served his country during the Korean Conflict as a proud member of the U.S. Army. Bill was united in marriage to Janet M. Herrmann on July 6, 1960 at St. Joseph's Catholic Church in Kellnersville. The couple was blessed with nine children and 65 years of marriage.

Bill was employed for many years as a die-setter and supervisor at Mirro Aluminum and later worked in maintenance for Martin School of Hair Design. He was also a certified auto mechanic. Bill will be remembered as "Jack of All Trades", as he could fix anything! He was always up for any woodworking, electrical, heating or plumbing job; he was eager to work on tractors and engines, and looked forward to any type of farm work needed for relatives or neighbors. He treasured the many years that he enjoyed deer hunting with his boys. Bill was a member of the NRA and longtime member of the American Legion Post #165 of Two Rivers.
