DeMarise was born on May 23, 1984, in Havre to William "Sonny Boy" and Lois (Potter) St. Mark.  She was raised in Great Falls, Billings, Spokane, Seattle, and Rocky Boy.  Following her school years, while in Spokane, DeMarise had a son and worked various jobs.  She returned to Rocky Boy, where she had a daughter and continued working hard to provide for her small family.  She had another daughter and then a son, and at that time DeMarise made the decision to stay home to care for her children.

She was a smart, strong woman who enjoyed gardening, painting, coloring, and photography.  DeMarise collected knick-knacks and was very artistic, sharing her love of crafts with her children.  She liked camping and going to Brown's beach with her kids and family, and family dinners were very important to her.  DeMarise was very outgoing and loved to joke around, but she was also very protective of her family and friends, and she adored her dogs and her new nephew Caesar "Silverwhip" .
