Rosalind J. Dietz, 80, of Elk Run Heights, passed away on Monday, August 17, 2026, under hospice care at MercyOne Medical Center-Waterloo.

Rosalind was born on Marcy 21, 1946, in Newfoundland Province, to Maxwell and Gwendolyn (Sparkes) Rowsell. She earned her GED and moved to the United States in 1964, later becoming a dual citizen of Canada and the U.S. Rosalind married Arlo Patterson in 1965, they later divorced. She later married Michael D. Dietz on June 18, 1994, at Concordia Lutheran Church in Waterloo; he preceded her in death on March 26, 2026.

As the youngest daughter amongst her 9 other siblings, at a young age Rosalind grew to love fashion, being “dolled up”, and never left the house without her lipstick. Her love for fashion and accessorizing was reflected in her wardrobe and her role at JC Penney’s where she was a Sales Associate for many years prior to retirement.

Rosalind loved taking trips back home to Canada and was very proud of her heritage and following Canadian Sports. She loved the decorating for the holidays throughout the year, spending time with her family, and everything Elvis and Toby Keith. She was a member of Grace Lutheran Church in Waterloo.

She is also preceded in death by her parents, siblings, Kevin, Doug, Ruby, Evelyn, Isabelle and Christina, and daughter-in-law, Janet Patterson.
