Mary was born on March 30, 1935 in Omaha, Nebraska, to Dr. Louis Cyril and Ann (Campbell) Walsh. She grew up in Omaha, and on July 23, 1955 she married Keith L. Cornelius, Sr. in Omaha. The pair celebrated 50 years of marriage, and Keith preceded Mary in death in 2006. Mary lived in a few different cities, but her main residences included Omaha, Moville, and the Martinsburg area. She held various jobs throughout the years, but her most important role was that of homemaker.

Mary’s hobbies included painting, fishing, gardening, swimming, and playing pool with her husband, Keith. She was an animal lover to her core and raised fish in her aquarium as one of her many hobbies. She
