She was the only daughter of the late Louis and Mary (Harper), Hamilton. She married her husband of 64 years, Joseph “Joe” Decker on November 20, 1954, in East St Louis, Illinois.

Mary worked as a homemaker while raising seven children. When they were grown, she was able to enter the workforce as a secretary at The Shrine of Our Lady of the Snows in Belleville and as a receptionist at the Rosewood Care Center in Edwardsville. She was a member of St Cecelia Catholic Church in Glen Carbon and of the Cenacle of Divine Mercy at St. Peter and Paul Catholic Church in Collinsville.

Dee was a woman of many artistic talents, including playing piano, painting and ceramics. She and her husband, Joe, loved to travel in retirement years. They explored most of the United States and Canada. She loved the sounds of the ocean, especially those of water over rocks.
