28. From Ronan's perspective, his father was having sex with his sister.

Soon-Yi was one of Mia Farrow's adopted children, and Allen was a father figure to them all. He was the legal father of Ronan, Moses, and Dylan.

Mia Farrow and Andre Previn adopted Soon-Yi only one year before they got divorced, and Mia started seeing Woody a year after that. So Soon-Yi had had Woody in her life since she was a 6 or 7 year old.

In 1970, Farrow married the conductor/composer André Previn after having become pregnant by him while he was married to songwriter Dory Previn.[31] His former wife wrote a scathing song, entitled "Beware of Young Girls", about the loss of her husband to Farrow.[32] Farrow and Previn had three biological children (twins Matthew and Sascha, and Fletcher). In 1973 and 1976, respectively, they adopted Vietnamese infants Lark Song and Summer "Daisy" Song, followed by the adoption of Soon-Yi (born c. October 8, 1972) from Korea around 1978. Soon-Yi's precise age and birth date are not known, but a bone scan estimated her age as being between 5 and 7 years old at the time of her adoption.[33] Previn and Farrow divorced in 1979.[34]

In 1980, Farrow began seeing film director Woody Allen. During their relationship, Farrow starred in many of Allen's films, and several of her relatives also made appearances. Together they adopted Moses "Misha" Farrow and Dylan Farrow. Dylan was known as "Eliza" for a while and later known as "Malone". In 1987, Farrow gave birth to their son Satchel "Seamus"[35] O'Sullivan Farrow,[36] later known as Ronan Farrow. However, in a 2013 interview with Vanity Fair, Farrow stated that Ronan could "possibly" be the biological child of her first husband Frank Sinatra, with whom she claims to have "never really split up".[37]
