Ralph James Duff Sr., born in Omaha, Nebraska, on April 7, 1933, passed peacefully in his sleep on the evening of December 5, 2025, at approximately 8:18 p.m., while residing at Estancia Del Sol Assisted Living in Corona, California.  He was 92 years old.

Ralph was a deeply devout Christian whose life was firmly rooted in faith.  An ordained minister, he dedicated much of his life to sharing the Gospel and serving his community with humility and compassion.

Throughout his life, Ralph wore many hats.  Dr. Duff was a pharmacist by profession, a successful business owner, a volunteer police officer, and a dedicated member of nonprofit boards.  He believed deeply in service, stewardship and sacrifice —reflected in his generosity, and unwavering commitment to causes dearest to him.

Ralph shared a remarkable marriage of more than 73 years with his beloved wife, Pearl Jane Duff (née Billingsley).  Together, they built a legacy grounded in faith and devotion.  He is survived by Jane; their six children; fourteen grandchildren; and twenty-three great-grandchildren, each of whom carries forward a piece of his enduring legacy.

While his absence is deeply felt, his family finds comfort in the assurance of eternal life and reunion through Christ.  Matthew 25:23 “Well done, good and faithful servant!… Come and share your master’s happiness!"

The Duff family welcomes your prayers and remembrances as they honor and give thanks for a life well lived.  A memorial service celebrating Ralph’s life and faith will be held on February 15, 2026.  In lieu of flowers, donations to Ralph’s memorial fund are deeply appreciated during this time.
