Mary was born March 7, 1958 in Cut Bank, Montana to Arthur G. and Glady (Limke) Tavary. She was raised and educated in Cut Bank graduating from Cut Bank High School. She moved to Havre to attend Northern Montana College where she obtained her Associate in Secretarial Technology. While attending college she met her soul mate Bruce McLain. The couple married September 6, 1980 in Cut Bank at St. Margaret's Catholic Church. Together they made their home in Havre and began their family. Bruce and Mary had four sons. Mary operated a daycare out of her home for many years. She enjoyed watching the kids grow and mature into adults. After her children were more independent she began working for other places: cleaning businesses, working at Taco Time, and Dairy Queen. DQ will never be the same. She donated a lot of time to her church, St. Jude's, volunteering as her children attended school and working as the Alumni Director for many years. Mary had a true gift for helping others; she put many people's needs before her own. She enjoyed the holidays; always making Christmas Goodie Plates for people. Her greatest joy was being a grandmother, life's reward after raising her children. Mary's favorite place was Lake 5 where her and her family vacationed every summer. Her family will continue to keep the tradition in her honor. She was a member of the St. Jude Catholic Church, Relay for Life and Weight Watchers.
