Diana Mae Hoffenbacker, 83, of Idaho Falls, passed away Wednesday, July 28, 2021, at the Gables of Ammon. She was under the care of Encompass Hospice.

Diana was born on November 10, 1937, in Butte, Montana, to Charles William Byrne and George Dell McLaughlin Byrne. She was one of the 'famous Byrne twins' among the earliest identical twins born by a caesarian. She grew up in Butte and graduated from Butte High School in 1956.

On June 30, 1957, she married Hubert H. Hoffenbacker in Butte. To this union, 5 children were born. They lived in Butte then moved to Idaho Falls. Hubert passed away on April 1, 2011. Diana worked as a nurse's aide while they lived in Butte. She enjoyed helping others and volunteered as a candy striper at St. James Hospital, as a docent at the Museum of Idaho, and ran the library at the Gables of Ammon.

She was a loving wife, mother, grandmother, sister, daughter, and friend who was fiercely loyal and protective of her family and friends. Those who were in her life meant everything to her. She was an avid reader who devoted many hours helping in the library to ensure others had access to the magic of literature which brought so much joy to her life. She will be greatly missed and lovingly remembered by those who knew her.
