Olive “Ollie” Brenna, 94, passed away peacefully on Friday, December 19, 2025, at the McKenzie County Hospital in Watford City, North Dakota.

Olive (Ollie) Juanita Hasby was born on Sept. 8, 1931, to Oscar and Josephine Hasby on the farm near Hampden, ND. Her father died in a farm accident prior to her birth. She was the youngest of 6 children. Her elementary school years were spent in a 1-room country schoolhouse near Hampden. She also attended school in Nekoma during the winter months. They sold the farm and moved to Sanish, ND, when her mother married Martin Froshaug in 1945.

Ollie met Clayton Brenna in the spring of 1947 and they were married on the Eldred Brenna farm on November 1st of that year. She spent many years on their farm raising their 5 children and helping with the farm. In 1971, they faced every parent’s biggest nightmare with the loss of their son, Terry, in a car accident. In 1980, Ollie and Clayton moved into New Town. With most of the children raised, Ollie was able to complete high school and attend college. She also studied to be an EMT with the New Town Ambulance Service. In 1996, Ollie and Clayton moved to Watford City and then to Minot in 2014. Ollie’s final move was to the Horizon Assisted Living, Watford City, in November of 2025. She passed away on Friday, December 19, 2025.

Ollie was always involved with her community whether it be church or other community organizations. She loved to sing and was most appreciative of band and piano music.
