The former actress died on Saturday afternoon at Cedars-Sinai Medical Center in Los Angeles.
Bertrand, who was partly of Native American descent, appeared in movies like Lookin’ to Get Out and The Man Who Loved Women, but gave up her acting career to raise her kids as a single mom, after divorcing their father, actor Jon Voight, in 1978.
She always stayed on the fringes of Hollywood and produced star-studded documentary Trudell in 2005.
Jolie confirmed her mother was battling ovarian cancer last month, but confessed she expected her to win her fight with the disease.
In a TV interview with CNN talk-show host Larry King, the actress revealed her mother was “doing good,” adding, “She has fought for six years and she’s a remarkable woman. She’s very, very strong and her spirit remains unbroken.”
