Jackie was born October 11, 1930 in Butte to parents Marjorie C. and Paul Best. She spent her early years in Butte, then moved with her parents to Sheridan, Montana while in grade school. Jackie attended Western Montana Normal College in Dillon where she received her teaching certificate. After college, Jackie taught third grade in Manhattan, Montana. The mother of one of her students, Pat Hughes, set Jackie up on a blind date with a young rancher from the Madison Valley named Steve McDonnell. It was a match that worked; Jackie and Steve were married in September of 1951. Jackie spent most of her adult life on the family ranch on the Madison Valley. She and Steve raised their son, Stephen Paul, on the ranch. Jackie never met a stranger and always had a place at the table for friends and family. She truly enjoyed playing a part in raising others, including John Coghlan and her grandchildren, John and Kellie. In later years, Jackie and Steve enjoyed snow birding in Yuma, Arizona. She immensely enjoyed family and all the friends that she made there.
