April 12, 1939 — June 11, 2025

Deanna Jean Cuthbertson Hirz, “Mimi”, a beloved resident of Moses Lake, Washington, passed away peacefully at her home, surrounded by family, on Wednesday, June 11, 2025. She was 86 years old. A joyous reunion with Ned took place on this day, which was also their 65th wedding anniversary. Born on April 12, 1939, in Klamath Falls, Oregon, Deanna was the daughter of Frederick Cuthbertson and Lenora Brown. Her family moved to Medford, Oregon when she was six months old, where she grew up. A graduate of Medford High School, Deanna embraced life with enthusiasm. She loved participating in school plays, she was a spirited majorette and cheerleader in the Bliss Band, and she lent her beautiful voice to the girls' choir. Deanna became a member of The Church of Jesus Christ of Latter-day Saints in 1954 at the age of 15. Even at age 12, before joining the church, she declared to her mother and aunt her intention to work on their family tree. Little did she know this spark would ignite one of her life's greatest callings. Beginning in 1959, Deanna dedicated her life to genealogy, meticulously indexing tens of thousands of names and passionately helping countless others discover their own family heritage. She joyfully served in many church capacities, including Stake Young Women's President and Counselor, Relief Society President, Primary President, teacher, compassionate service leader and chorister. She loved working with the youth.
