Mary Kay to many, Nana to a couple, Mom to one.

Mary Kay was born in Minneapolis, Minnesota, on February 8, 1947 to James Bruce Phillips and Frances Irene (Schabel) Phillips. Mary Kay attended Holy Family School in her youth and was a parishioner at Holy Name Catholic Church. Mary Kay graduated from Hammond High School in Hammond, Indiana in 1965. Mary Kay married J. Edward Costley III on September 17, 1966. The couple was blessed with one child, Kristen, on April 13, 1972. Mary Kay worked at The Hammond Times as a Classified Advisor from January 1976 - June 1979. She often reminisced about this time in her life. Mary Kay moved to Coffeyville with her parents and daughter in 1979. After moving to Coffeyville, Mary Kay held several occupations before finding her true calling at Tri-County Special Education Cooperative in Independence, Kansas. Through hard work and dedication, Mary Kay was promoted throughout her years with this agency and retired as Deputy Clerk of Tri-County.

Mary Kay took great pride and joy in sewing Halloween costumes for her two grandchildren. She often spent months searching for the right patterns and materials, and the end results were nothing short of spectacular. Christmas, however, was her favorite holiday. She enjoyed buying Christmas ornaments for her grandchildren each year that were unique to their interests and personalities. Mary Kay invested significant time and energy decorating her home for Christmas. Her Christmas tree was a sight to behold. Mary Kay enjoyed attending athletic events and activities for her two grandchildren. Later in life she became interested in genealogy along with her niece.
