Sian Barbara Allen in The Waltons (1972)
Francesca Kinsolving, a very pregnant widow whose husband was recently killed in action in Vietnam, travels to visit her late husband's mother in a snowy Minnesota town and gets snowed in with her during a fierce blizzard. Forced to wait it out, she slowly uncovers some terrible dark secrets that her mother-in-law has been hiding, such as her psychotic other son, who has recently escaped from the asylum and is shacked up in the basement.

Sian Barbara Allen was born Barbara Susan Levey in Reading, Pennsylvania, on July 12, 1946. She later adopted her stepfather's surname (Pokrass). She had two sisters. She studied at the Pasadena Playhouse from 1964 to 1965. Her performance as the mentally challenged Kathleen in You'll Like My Mother (1972), opposite Patty Duke, Rosemary Murphy, and Richard Thomas, earned her a 1973 Golden Globe nomination for "Most Promising New Actress".

While working on 'You'll Like My Mother,' Allen met and fell in love with the man playing her character's psychopathic brother, actor Richard Thomas. The two began a relationship that lasted for several years in the 1970s. Thomas went on to play John-Boy on the hit TV show The Waltons (1972). When the writers of "The Waltons" wanted to do a love story for John-Boy in the first season, Thomas suggested that his real-life girlfriend play his onscreen love interest. Allen appeared as Jenny Pendleton in the episode The Love Story (1973), which earned Thomas his Emmy award in 1973, and in The Thanksgiving Story (1973).

Allen portrayed the titular character Peggy Johns in the 1973 TV movie Scream, Pretty Peggy (1973), with Bette Davis and Ted Bessell. Allen worked steadily as a TV actress throughout the 1970s, appearing on such shows as The Rockford Files (1974), Ironside (1967), Bonanza (1959), Gunsmoke (1955), and many others. She also wrote a script for an episode of the fourth season of Baretta (1975). Her last onscreen role was in the L.A. Law (1986) episode Whatever Happened to Hannah? (1990).

Allen ended her acting career after marrying and giving birth to a daughter. She later channeled her creativity into writing. She was the older sister of flash-fiction author, editor, and teacher Meg Pokrass.

Allen died in 2025, aged 78, after a long battle with Alzheimer's disease.
