Bertha Mae Mangum

August 27, 1927 ~ May 24, 2020 (age 92)


Like the bright and warm sun after a cold and stormy week, Bertha Mae Cazier Mangum, 92, was relieved of her earthly struggles and found peaceful rest as she passed from this earthly life on Sunday morning, May 24, 2020 at Quinn Meadows Rehabilitation and Care Center.
Bertha was born August 27, 1927 in Idaho Falls, Idaho to George and Emily Cazier. She was the oldest of four children, with two sisters and a brother. When she was only 11, her mother was left to raise the children alone. Having to go to work to support them, much of the daily care of her siblings rested upon Bertha’s shoulders.
Shortly after, while performing in an Easter program together, she became acquainted with Lester Joseph Mangum and began a sweet courtship that resulted in marriage on January 30, 1943. Soon after their marriage, Lester was drafted into the Army and served in WWII, stationed in Iceland where he served until the war ended in 1945. During that time, Bertha gave birth to their first son, Lester Joseph, Jr. (Joedy). On December 28, 1944, when Lester was home on leave, they were sealed as a family for eternity in the Salt Lake Temple. When Lester returned home for good, they started building their life together in St. Anthony, Idaho. While living there, their daughter Linda Jean was born in Idaho Falls. In 1950, they moved to Casper, Wyoming where their third child, Scott Lamar was born. They later lived in Rawlins, and then made a big move to Redding, California where they finished raising their children. Later moves took them to Pacifica, Fresno, and Orangevale, California and then to Pocatello, Idaho. Everywhere they went, Bertha treasured her neighbors and friends. She loved visiting and spending time with them, and so appreciated the relationships she had with them.
Bertha worked for several years as a nurse’s aide at hospitals in Wyoming. She liked helping others and was really good at what she did. After raising her own family, she provided childcare to several sweet children she claimed as hers and were as dear to her as her own grandchildren. She loved little ones and was a kind and gentle Grandma. The grandchildren and great-grandchildren she lived near through the years loved being at her house. She has left behind a large posterity of loved ones, including 11 grandchildren, 38 great-grandchildren and 15 great-great-grandchildren.
She was a member of the Church of Jesus Christ of Latter-day Saints and served in several capacities through the years. Her favorite by far was serving as the meeting house librarian. She thrived in this quiet, organized space and loved being able to serve where she was most comfortable.
Not long after her 90th birthday celebration, an accident at home resulted in surgery and rehabilitation at Quinn Meadows. Because of her frail bones and arthritis, her body never fully recovered to allow her to return to her own home. She was loved by the staff and nurses there and known for her beautiful smile which she was always quick to share. Her family is so grateful for the respect and tender loving care given her over the last two and a half years by the people who attended to her there, as well as the compassionate staff at Encompass Health.
She was preceded in death by her husband Lester, her son Scott, a sister, brother, and two great-grandsons. She is survived by her son Lester (Christine) Mangum, Jr. of West Haven, Utah and her daughter Linda (Allen) Dixon of Pocatello, Idaho, her daughter-in-law Beth (Scott) Mangum of Citrus Heights, California and her sister Jean (Jack) Sheffer of Idaho Falls, Idaho.
To celebrate her life, a Graveside Service will be held Saturday, May 30th at 2:00 p.m. at Fielding Memorial Cemetery, 4600 S. Yellowstone Hwy., Idaho Falls. The family requests that guests be sensitive to medically vulnerable family members that will be in attendance. Services will also be live on Cornelison Funeral Home Facebook page.
