Tiffin's father, Stanley Wonso, was an architect. Her paternal grandparents hailed from Poland (Siedlce and Wilno, respectively).
Named "Star of Tomorrow" in 1962 by the Motion Picture Herald, a trade
paper for theater owners.
The February 1969 issue of "Playboy" Magazine did a feature on her
entitled "A Toast to Tiffin," showing tastefully nude photos of her
with long and flowing golden hair. The photos concealed her nakedness
with flowers, fabrics and strategically-placed objects. "Playboy" offered
her quite a bit of money in the ensuing years to do a full spread but
she always refused.
Upon her death, she was cremated and her ashes returned to her surviving spouse. She was also survived by her daughters, Echo Angelica (b. June 11, 1976) and Aurora Hillego Danon (b. February 12, 1981).
Attended Hunter College while modeling and soon became one of New York City's top models, even making the cover of "Vogue" magazine. She later attended the Stella Adler Studio of Acting.
