It is with heaviest of hearts that we announce the peaceful passing of ISABELLA ROSA MAINZER HOLBERTON, aka “Izzy” or “Chick” of Lethbridge, AB, at St. Michael’s Health Centre – Palliative Care Unit, on Tuesday, June 18, 2024 at the age of 73 years, following a courageous battle with cancer.

Isabella will lovingly be embraced by her father William Leslie Holberton; mother Elizabeth Mable Mildred Harrison; stepfather Colin Preece; sisters, Hazel Ulvestad and Georgia Ajtai; twin brother Thomas Holberton (who loved to point out he was 15 minutes older); and granddaughter Brianna Wiskerke. Isabella sadly leaves to mourn her passing, her son Sean (Amanda) Mainzer; daughter Tammy (Trevor) Millward; grandchildren, Devin Millward (Courtney Galenzoski), Nash Millward (Kirby Stevenson), Triston McMillan (Rachel Vavrik), Cloe Millward (Randy Teeple), and Jada and Addison Mainzer; great-grandchildren, Axton, Huxton, Hartlen Millward and Ledger Lowry; and sister-in-law Kathy Holberton of Edmonton, along with many nieces, nephews and friends.

Isabella dedicated her life to her family and friends, and absolute love of helping others as a Health Care Aide. She loved swimming competitively in her youth alongside her siblings. Mom had a deep passion for the sport of hockey and was known for her unwavering love of her team, the Calgary Flames, and for the game.

Special thanks to Mary Bartell for being the best conversationalist and entertainer to Mom, Sean and Tammy, for the hours of stories and laughter in our time of need.

At Mom’s request, a Celebration of her Life will be held at a later date for family and close friends.

In lieu of flowers and in memory of Isabella, donations may be made to the Canadian Cancer Society (cancer.ca), Canadian Red Cross (redcross.ca) or charity of one’s choice.
