NEW YORK - Lynn Redgrave, an introspective and independent player in her family's acting dynasty who became a 1960s sensation as the unconventional title character of "Georgy Girl" and later dramatized her troubled past in such one-woman stage performances as "Shakespeare for My Father" and "Nightingale," has died. She was 67.

Her publicist Rick Miramontez, speaking on behalf of her children, said Redgrave died peacefully Sunday night at her home in Kent, Conn. Children Ben, Pema and Annabel were with her, as were close friends.

"Our beloved mother Lynn Rachel passed away peacefully after a seven year journey with breast cancer," Redgrave's children said in a statement Monday. "She lived, loved and worked harder than ever before. The endless memories she created as a mother, grandmother, writer, actor and friend will sustain us for the rest of our lives. Our entire family asks for privacy through this difficult time."

Redgrave was diagnosed with breast cancer in December 2002, had a mastectomy in January 2003 and underwent chemotherapy.

Her death comes a year after her niece Natasha Richardson died from head injuries sustained in a skiing accident and just a month after the death of her older brother, Corin Redgrave.

The youngest child of Michael Redgrave and Rachel Kempson, Lynn Redgrave never quite managed the acclaim - or notoriety - of elder sibling Vanessa Redgrave, but received Oscar nominations for "Georgy Girl" and "Gods and Monsters," and Tony nominations for "Mrs. Warren's Profession," ''Shakespeare for My Father" and "The Constant Wife." In recent years, she also made appearances on TV in "Ugly Betty," ''Law & Order" and "Desperate Housewives."

"Vanessa was the one expected to be the great actress," Lynn Redgrave told The Associated Press in 1999. "It was always, 'Corin's the brain, Vanessa the shining star, oh, and then there's Lynn.'"

In theater, the ruby-haired Redgrave often displayed a sunny, sweet and open personality, much like her ebullient offstage personality. It worked well in such shows as "Black Comedy" - her Broadway debut in 1972 - and again two years later in "My Fat Friend," a comedy about an overweight young woman who sheds pounds to find romance.

Redgrave's play "Nightingale" at off-Broadway's Manhattan Theatre Club in 2009 was the last time she appeared on stage in New York. Lights on Broadway marquees will be dimmed Tuesday.

"She was adored by audiences, and although she embarked on a medical treatment as previews began, she never missed a show and gave magnificent performances eight times a week," said Lynne Meadow, artistic director of MTC.

"We admired her strength, her talent, her courage and her enormous good heart. There wasn't a stage hand, a press rep, a box office person who didn't worship Lynn. She was true theatre royalty."

Tall and blue-eyed like her sister, she was as open about her personal life as Vanessa has been about politics. In plays and in interviews, Lynn Redgrave confided about her family, her marriage and her health. She acknowledged that she suffered from bulimia and served as a spokeswoman for Weight Watchers. With daughter Annabel Clark, she released a 2004 book about her fight with cancer, "Journal: A Mother and Daughter's Recovery From Breast Cancer."

Lynn Redgrave is survived by six grandchildren, her sister Vanessa, and four nieces and nephews.

A private funeral will be held later this week.
