Tracy was born on February 10, 1972 in Joliet, Illinois to James and Sandra (Pierson) Corbley.      She was a graduate of Hurley High School. She later graduated from Northland College with a Bachelor''s degree in Education.      On May 21, 2005 she was united in marriage to Bill Niehaus at St. Isaac Jogues Church in Mercer. Their marriage united Tracy, Bill and her son Jim as a family. Later, their son Ayden joined the family, first as their foster son and later, he was adopted by Tracy and Bill. In her younger days, she was employed with her family business, Lake''s Distributing and Pine Lake Lodge. On July 3, 2003 she joined the Iron County Sheriff Department as a Dispatcher. She loved her co-workers. She also loved helping friends and family and could always be counted on by those in need.      Tracy loved time with her family and hosting outdoor cook-outs for her family and friends. She loved the outdoors, cross-country skiing and snowshoeing. She was a proud participant in the Book Across the Bay, Stormy Kromer and the Noquemanon Ski Marathon in Marquette. She was very happy to have placed in her class, but often joked about how she was passed by elderly women and kids on the way to her victory. She enjoyed camping at Saxon Harbor, morning coffee on her deck while watching her boys fish off the dock. On a warm spring day she could often be found sitting on the porch in the sun, watching the snow melt.
