Diana Rose Davidian

Diana Davidian, most recently of Conroe, Texas, passed away peacefully on April 23, 2026. Diana had been a resident of Atascadero, California for 22 years before moving to Texas to be near her loving family.

Diana was born in Visalia, California, to John and Sue Davidian on December 15, 1945. When Diana was just two years old, she lost her mother Sue in a tragic car accident. In her younger years, she was lovingly raised by her grandparents, Giragos and Aghavni Davidian. Later, she was blessed with the love and guidance of Annie Ananian Davidian, who became her mother in every way that mattered.

Diana and her brother Greg attended Monson-Sultana Elementary School, and Diana later graduated from Dinuba High School.

Diana married Jay Higbee in 1967, and together they were blessed with a daughter, Keleen, in 1972. Later, Diana married David Biswell, and they joyfully welcomed a second daughter, Alyssa, in 1980.

Throughout the years, Diana worked periodically as a legal assistant for a Dinuba attorney and also for the Tulare County Sheriff’s Department.

More than anything, Diana loved being a mother to her two daughters. She was deeply involved in their lives—supporting them in all of their activities. Diana’s home was always open to her daughters’ friends, and she had a gift for making people feel welcome. She loved having guests in her home and was always willing to help a friend in need.

Life took a heartbreaking turn in 1994 when Diana lost her beloved 14-year-old daughter, Alyssa, to leukemia. Though that loss stayed with her forever, her heart opened again when her daughter Keleen blessed her with three grandsons, who became the loves of her life.

In 2003, Diana moved to Atascadero to be closer to Keleen, Dave, and the boys. She made her home there for more than two decades before recently relocating to Texas so she could be near her first great-grandchild, Joy. Diana was grateful to have the opportunity to meet and spend time with her before her passing.

Diana had a deep love for the ocean, where she felt most peaceful and closest to Alyssa.

Diana is survived by her daughter Keleen and son-in-law David Miller of Texas; grandson Noah Miller, his wife Faith, and their daughter Joy; grandson Mason Miller and his fiancée Emily; grandson Hunter Miller; sister-in-law Margie Davidian; nieces Annie and Sara Davidian; great-nephew Gregory Davidian; great-niece Skylar Davidian; and numerous beloved family and friends.

She was preceded in death by her parents John, Sue, and Annie Davidian; her daughter Alyssa Biswell; her brother Greg Davidian; her aunt Rose Tamuzian; her grandparents Giragos and Aghavni Davidian; and Kaloust and Kaghstrig Ananian.

Services will be held at St. Mary Armenian Apostolic Church in Yettem on Friday, May 29, 2026, at 10:30 a.m., immediately followed by a memorial luncheon. Burial will be private at Visalia Public Cemetery District.
