Mia Farrow's Sister, Actress Tisa Farrow, Dead at 72: 'She Was the Best of Us'

Actress Theresa "Tisa" Farrow, known for films such as Homer and Fingers, has passed away. At the time of her death she was 72 years old.

Mia Farrow, a fellow actress and sister of Tisa, regrettably announced the news on Instagram on Wednesday. In addition to a throwback photo of her late sibling, Farrow posted a lengthy, sincere tribute, as PEOPLE reported.

"If there is a Heaven, undoubtedly my beautiful sister Tisa is being welcomed there," began the Rosemary's Baby actress, 78. "She was the best of us — I have never met a more generous and loving person. She loved life & never complained. Ever."

"She died unexpectedly yesterday morning. Apparently in her sleep," Mia also wrote. "This is a hard time for all of us who admire and love her so deeply."

Ronan Farrow commented on his Instagram Story on Thursday, reposting his mother's eulogy and writing, "Miss you, Auntie Tisa."

The Hollywood Reporter noted that on July 22, 1951, Irish actress Maureen O'Sullivan and Australian director John Farrow welcomed their youngest child, Tisa, who was the youngest of seven.

Farrow's Professional Career

Tisa appeared in over a dozen more films after her début as Laurie Grainger in the 1970 drama Homer, including And Hope to Die (1972), Fingers (1978), Winter Kills (1979), and Woody Allen's Manhattan, also in 1979.

In 1980, she made her final film appearances as Julie in Anthropophagus and Jane Foster in The Last Hunter.

Tisa, who was 18 years old at the time, told the New York Times in 1970 that she had "no advantages" in the industry and "spent a long time going around town trying out for commercials, and I didn't get one."

"I would always run into some career woman who disliked me right away because she didn't like my sister Mia," she added.

Well Wisher's Response

After concluding her film career, Tisa spent the next 27 years as a nurse, Mia, herself a mother of 14, noted in an Instagram tribute to her sister.

"[She was] a wonderful sister to Steffi, Prudence and me, a devoted mother to Jason, who died in Iraq, Bridget and little grandson Kylor — the lights of her life," Mia added.

Elizabeth Perkins, among the celebrities who extended condolences, stated to Mia, "I am so deeply and terribly sorry."

"I'm so sorry," wrote Molly Ringwald, while Tatum O'Neal left a rose emoji and Frances Fisher commented with a prayers-hands emoji.

"Ohhhh, Mia, I’m so very sorry for this shocking and devastating loss," said Lesley Ann Warren. "My love and prayers for grace for you and your family."
