Upon graduating Yukon High School in 1958, Mary Kay attended two years at her beloved Oklahoma State University, and then married her sweetheart, Jim Niles on July 30, 1960.

In 1963, after Jason, their first born arrived, she dedicated her next twenty-three years to her three children, Jason, Jill, and Troy. Mary Kay worked several part-time jobs but later pursued working at the Oklahoma State Capitol where she worked as an assistant to several members of the State House of Representatives. As an assistant to Frank Lucas, she loved working for him and helping him pursue the United States House of Representatives. She continued working for his office in Oklahoma for several years.

Mary Kay had the gift of hospitality, a great sense of style, and a true appreciation for the beautiful. She loved entertaining, traveling, fashion, and shopping. Her inquisitive and amiable nature-one who never met a stranger-also had a fiery side. Known by many as a lively and spirited debater who dearly loved her Cowboys, Mary Kay will be sincerely missed by all.
