Donald Erwin Olson, 91, a life-long resident of Olson Road in Ironwood Township, passed away Wednesday, Feb. 9, 2011, in Ironwood.      Don was born March 9, 1919, in Ironwood, son of the late Lillie (Fell) and Carl Hjalmer Olson, attended Ironwood Township schools, and graduated from Luther L. Wright High School in 1936.      He married Anna Marie Rye on June 23, 1945. Together, they built a home on Olson Road where they raised nine children. Don and Ann celebrated their 65th wedding anniversary in 2010.      Don and his brother, Gerhard, built and operated Sunset Dairy on Olson Road until they merged with Blue Ribbon Dairy, becoming Consolidated Dairies in Bessemer. He retired in 1981.      Retirement found time for woodworking and making furniture for all of his children and grandchildren. A few hand made oak roll top desks and other pieces found their way to lucky people outside of the family. Don cut the trees from his and Gerhard's land, milled them at his sawmill and worked out of his basement shop. He loved playing cards (smear), growing vegetables, playing the mandolin and sitting out on the bench in the evening. He is missed.      Surviving are his wife, Ann; eight children, Donna (Jim) Finley, Ironwood Township, Donald (Sandy) Olson, Harbor Springs, Judy (Walt) Hemes, North Lake, Wis., Robert (Colleen) Olson, Niceville, Fla., Susan Olson, Fontana, Wis., Cheryl (Greg) Cosgrove, South St. Paul, Minn., and Dale and Dan (Paula) Olson, both of Ironwood Township; 25 grandchildren and 20 great-grandchildren; a brother, Gerhard Olson, Ironwood Township; and numerous nieces and nephews.      Besides his parents, he was preceded in death by a daughter, Marilynn Loreti; two brothers, Ronald in infancy and Lawrence; and a sister, Lois Prezkop.      Out of respect for Don's wishes, cremation has taken place.      A private family spring memorial service is planned.      Inurnment will be in Sunset Acres Cemetery, Ironwood Township.      Memorial contributions may be made to the Our Lady of Peace Adopt-A-Student Program, 108 So. Marquette St., Ironwood, Mich. 49938, or the Salvation Army, P.O.
