Marion A. “Henny” Cooper, age 94, of Saukville, Wis., peacefully passed away on Feb. 23, 2026, surrounded by her loving family at Compassionate Heights assisted living center in Beechwood, Wis.

She was born on May 31, 1931, in Pound, Wis., to her late parents John and Flora (nee Thurow) Seefeldt. Marion was the last of eight children and had a twin sister Mille, who preceded her in death on Aug. 11, 2013. Mille and Marion had a special bond and were known to enjoy a Manhattan or two when they got together to “visit.”  Marion loved to visit and had a very kind soul.

Marion was united in marriage to Donald “Don” Cooper on Oct. 13, 1951. Their marriage spanned 74 years and was blessed with three children, the late Connie (Bell), Robert (Dena) Cooper and Richard (Jill) Cooper.

Through the years, Marion enjoyed being a homemaker but also worked as an assembly worker for Lake Central Leather Co., Tecumseh Products and finally as a panel wirer for Allen Bradley Co.

For many years, she taught Sunday school and was a member of the choir at Pilgrim United Church of Christ in Grafton, Wis. She and Don were charter members of the church.

Later in life she enjoyed babysitting her grandkids, taking scenic walks around their hobby farm in Saukville, Wis., and birdwatching.

Marion is survived by her loving husband Don, two sons, Robert and Richard, 10 grandchildren, 13 great-grandchildren, other family members and friends.
