Her longest running soap opera role was Susan Ames on THE SECRET STORM from 1964-1971. She also played Barbara Vining on GENERAL HOSPITAL in the 1970s. Her first soap role was Molly Scharf on KITTY FOYLE.
Behind the camera, Lewis was a producer on TEXAS, and she won a Writer's Guild Award in 1985 for her work on SEARCH FOR TOMORROW.
In between soap gigs Lewis appeared in a number of films, TV movies and television series.
In her 1994 best seller, "Uncommon Knowledge," Lewis reported that she was conceived in 1935 when Young and Gable were filming a Yukon adventure, The Call of the Wild.
Gable was married to his second wife and Young was single at the time. Because she had a morals clause in her contract with 20th Century Fox, Young hid the pregnancy and birth, and 19 months later told the public she had adopted a daughter. When Young married Thomas Lewis in 1940, her daughter took his name, but he never adopted her.
Lewis is survived by her daughter Maria Tinney Dagit and grandsons Michael and Gregory, as well as half brothers Christopher and Peter Lewis; half brother John Clark Gable; and her longtime partner, Steve Rowland.
A Memorial Mass will be at 11:30 a.m. Saturday, Dec. 3, at St. John Vianney Church, Youngsford Road and Route 23, Gladwyne. Friends may call from 11 a.m.
