Barbara Siderius, 86

Barbara Jane Siderius, 86, beloved wife, mother, grandmother, and friend, passed away peacefully on May 21, 2025, in Kalispell.

Barbara was born on Feb. 18, 1939, in Memphis, Tennessee, to C.I. and Clara Jane Marsh. After graduating from high school in 1957, she embarked on an adventurous career as a stewardess with American Airlines. While living in Dallas, she met the love of her life, Jerome "Jerry" D. Siderius, an officer in the U.S. Air Force. The two were married on Dec. 17, 1960, in Waco, beginning a lifelong partnership filled with love, laughter, and devotion.

Barbara and Jerry raised a loving family together. She is survived by her husband Jerry and their children, Robin (husband, John and children, Mitch — wife, Olivia, Alex, and Jack — wife, Aya and son, Noah), Chuck, and Paul (wife, Sarah and children, Katie, Emma, and Abby). She is also lovingly remembered by her grandchildren, Joe (wife, Bre and their children, Josephine and Adilet), Reid and Shea, the children of Mike and Joan. Barbara is also survived by her brother, Wayne Marsh and his wife, Bennie.

She was preceded in death by her son, Mike and daughter-in-law, Joan.

Known for her gentle spirit, patience, and inner and outer beauty, Barbara left an indelible mark on everyone who knew her. She was a devoted and nurturing mother, and truly flourished as a grandmother, lovingly known as "Nanny" to her many grandchildren. Her warmth, grace, and steady love enriched the lives of her family and friends.

Barbara will be deeply missed, but her family finds peace knowing that she is at home in heaven, where her arrival is surely being joyfully celebrated.

A memorial service will be held Saturday, June 7, at 10:30 a.m. at First Presbyterian Church. 540 S. Main St., Kalispell. 

In lieu of flowers, the family asks that you honor Barbara by extending a kindness to someone in need — just as she so often did in her own quiet, beautiful way.
