Since Dylan Farrow penned an open letter revealing details of the sexual abuse she claims happened 20 years ago at the hands of her adopted father Woody Allen, relatives on both sides of the complicated family tree have been publicly taking sides.

Farrow, along with her brothers Moses and Ronan, were at the center of a 1993 custody battle between the famed director and their mother, actress Mia Farrow. The couple ended their 12-year-relationship after Allen began a relationship with Mia Farrow's then 19-year-old daughter Soon-Yi Previn, whom she had adopted with ex-husband, composer Andre Previn.

Dylan's Brother Moses Says Mia Farrow, Not Woody Allen Was Abusive

At the time of the breakup, Mia Farrow accused Allen of molesting Dylan. Allen has consistently denied the abuse allegation, maintaining his ex coached their daughter into making the claims, and Connecticut authorities ended their investigation into Allen without filing any charges against the director. Allen then married Soon-Yi in 1997.

But the allegations resurfaced earlier this month after the Times published Dylan's open letter, in which she claimed when she was 7, Allen led her to a "dim, closet-like attic" and "then he sexually assaulted me."

Since then, members of the extensive clan - Mia Farrow has 14 kids from her marriages and adoptions, six Previns and eight Farrows - have spoken out, including those pictured in this photograph of the family in Leningrad in 1987.

Keep reading for a quick who's who, and where they stand on the allegations. From left to right:

Ronan Farrow (held by Lark Previn): Mia Farrow gave birth to Ronan, now 26, during her longtime relationship with Allen but recently suggested that Frank Sinatra might be his father. Born Satchel, Ronan, a former special adviser to the State Department under Hillary Clinton and now host of his own MSNBC show, is estranged from Allen. "He's my father married to my sister. That makes me his son and his brother-in-law. That is such a moral transgression," Ronan has said. Last Sunday, he tweeted in support of Dylan, "I love and support my sister and I think her words speak for themselves."

Lark Previn: One of three adopted daughters, including Daisy and Soon-Yi, during Mia Farrow's second marriage to composer Andre Previn, Lark died in 2008 of complications from pneumonia.

Woody Allen (holding Dylan Farrow): Allen, 78, denied Dylan's renewed claims of abuse in a statement from his attorney. "It is tragic that after 20 years a story engineered by a vengeful lover resurfaces even though it was fully vetted and rejected by independent authorities. The one to blame for Dylan's distress is neither Dylan nor Woody Allen," Allen's attorney Elkan Abramowitz said in a statement to CNN. Allen's sister, Letty Aronson, told People he is devastated by Dylan's letter. "He feels very badly for Dylan, that she has been so poisoned by her mother."

Dylan Farrow: At the heart of the renewed family drama, Dylan, who was adopted by Farrow and Allen, is not backing down from her open letter. She told People Wednesday, "My memories are the truth and they are mine and I will live with that for the rest of my life. My mother never coached me. She never planted false memories in my brain. My memories are mine. I remember them. She was distraught when I told her. When I came forward with my story she was hoping against hope that I had made it up. In one of the most heartbreaking conversations I have ever had, she sat me down and asked me if I was telling the truth. She said that Dad said he didn't do anything. And I said, 'He's lying.'"

Fletcher Previn: The youngest of Mia Farrow and Andre Previn's three biological children. He also has older twin brothers Matthew and Sascha Previn. In a November 2013 Vanity Fair article, Fletcher was characterized as Mia Farrow's protector, having painstakingly edited Woody Allen out of every single family photo and video. "We can look at them and be reminded of the good and not be reminded of the bad," he told the magazine.

Daisy Previn: The second adopted daughter of Mia Farrow and Andre Previn, Daisy has not weighed in on the latest turn of events, but she told Vanity Fair in November 2013 that the Soon-Yi affair and abuse allegations, "turned our world upside down. It was nothing you would wish on anyone."

Soon-Yi Previn: The third adopted daughter of Mia Farrow and Andre Previn, Soon-Yi has been married to Allen since 1997 and they have two adopted daughters.

Moses Farrow: Dylan's brother, like her, was adopted by Mia Farrow and Allen when he was 2. Following the bitter custody battle, Mia Farrow was awarded custody of Moses and his siblings, but now Moses, a family therapist, is close to Allen and Soon-Yi and estranged from Mia Farrow and many of his siblings. "Of course Woody did not molest my sister," Moses told People Wednesday. "She loved him and looked forward to seeing him when he would visit. She never hid from him until our mother succeeded in creating the atmosphere of fear and hate towards him. The day in question, there were six or seven of us in the house. We were all in public rooms and no one, not my father or sister, was off in any private spaces. My mother was conveniently out shopping. I don't know if my sister really believes she was molested or is trying to please her mother. Pleasing my mother was very powerful motivation because to be on her wrong side was horrible." Moses said his mother "drummed it into me to hate my father for tearing apart the family and sexually molesting my sister," and that he now sees it as her "vengeful way to pay him back for falling in love with Soon-Yi."

Dylan called her brother's comments "lies" and "a betrayal," telling People, "My brother is dead to me."

Mia Farrow: Mia Farrow, 69, is standing by her daughter. ABC News was unable to reach her for comment, but on Twitter Tuesday, she wrote, "I love my daughter. I will always protect her. A lot of ugliness is going to be aimed at me. But this is not about me, it's about her truth."
