Stevensville – It is with a heavy heart that the family of Phyllis Marie Williamson Clevidence announces her passing at the age of 92. Phyllis was born on Willoughby Lane in Stevensville, Montana on August 15, 1933, and passed peacefully at her home on Willoughby Lane on Sunday, February 15, 2026, with family by her side.
She was preceded in death by her parents Harley and Irene Zeiler Williamson, her brothers Harley Williamson Jr and Marvin Williamson and husband of 62 years, Maynard Harold Clevidence in 2010 and beloved great-grandson Andrew Barry. Phyllis lived a full life raising two children, Steve and Jan, who she was very close to. Phyllis had no end of joy with her five grandchildren, 14 great-grandchildren and two great-great-grandchildren, who she was extremely proud of. She will be remembered for her love of birds, the thriving garden, flowers and the yard she made for them, as well as the elaborate, made-from-scratch family dinners and award-winning apple pie.
Phyllis is survived by her son Steve Clevidence (Kay) and daughter Jan Grenfell (Robert), her grandchildren: Dana Jenkins (Steve), Chris Grenfell, Stacy Kampka (Ben), Ryan Clevidence (Tonya), and Sara Clevidence (Mars); her great grandchildren: Bridger (Jamie), Hunter (Spencer), Denver, Logan, Hudson, Alivia (Caydon), Isabella, Ryker, McKenna, Bella, Will, Mason and Georgia; and great-great grandchildren Paxton and Kaysen.
Phyllis was a life-long member of Stevensville Methodist Church. We will miss her but take comfort that she is in the arms of the Lord and with her beloved husband who she missed so much.
Memorials may be made in her honor by donating to the Victor Cemetery (PO Box 1, Victor MT 59875) or a charity of your choice. The family will be holding a graveside service at the Victor Cemetery on Tuesday, March 3, 2026 at 2:00 p.m.
Special thanks to Bitterroot Hospice and Angels in Guard aide Karen, who took such great care of Phyllis the last year. Their kindness and comfort were appreciated more than words can express. Condolences and memories may be shared with the family at www.whitesittfuneralhome.com.
