Pretty Little Liars family tree

Four of the friends of the missing Alison DiLaurentis stand at the centre of the Pretty Little Liars family tree. Hanna Marin is the daughter of Ashley and Tom Marin. Tom has left the family, and Bustle calls Ashley the favourite single mother of the town.⁸ Aria Montgomery is the daughter of Byron and Ella, and Byron has an affair with Meredith that he presses Aria to hide.⁸

Emily Fields is the daughter of Wayne and Pam Fields. Bustle ranks Wayne among the best fathers of the series and names Pam the most improved parent, after her cold first response when Emily comes out.⁸ Spencer Hastings is the daughter, as far as Season 1 knows, of Peter and Veronica Hastings, and the sister of Melissa.⁸

The chart also draws the partners whom the finale settles. Aria marries Ezra, Hanna is married to Caleb and expecting a child, and Spencer ends the series with Toby.³ Mona Vanderwaal stands beside Hanna, the friend she lost to the other girls.⁵

Spoilers from here on. Peter Hastings is the father of three children by three women. Melissa is his daughter with Veronica. Jason DiLaurentis is his son by an affair with Jessica DiLaurentis, and Spencer is his daughter with Mary Drake, the identical twin of Jessica.²

Spencer was adopted by Peter and Veronica after her birth, so Melissa and Jason are both her half siblings.² Refinery29 set out that tie in May 2017, during the last season, so the Pretty Little Liars family tree draws it from Season 7.²

The finale adds a twin. Mary bore two girls, and the doctor offered her money for her freedom in exchange for the first child. The second, Alex Drake, was kept a secret from the Hastings and grew up alone, without family or friends.³ She is A.D., and she takes Spencer’s place to have her life and Toby.³

Kenneth and Jessica DiLaurentis are the parents of Alison, and Jessica is the mother of Jason.^2,8 Bustle ranks Kenneth last among the parents of the series, and Jessica is dead by the time it writes, after burying her own daughter alive.⁸ The chart draws Kenneth as Jason’s father until Season 7. From that season Jason hangs from Jessica alone, and the dashed red line from Peter marks his father.² Alison is believed dead from the start. The Season 3 finale shows that she is alive, and in Season 5 she comes home to Rosewood and goes to the police, so the words under her name change at those seasons, and the broken cross after her name stays only while she is believed dead.¹

In Game Over, Charles, the summer finale of Season 6, the series reveals that CeCe Drake is Charles DiLaurentis, the estranged child of the family, and that she is A. The A.V. Club recap notes that CeCe had transitioned and attended the funeral that the family held for Charles.⁷ Charlotte is therefore the adoptive sister of Alison and Jason.²

Season 7 changes her place on the Pretty Little Liars family tree again. Charlotte is the biological daughter of Mary Drake and Pastor Ted, the former partner of Ashley Marin, which makes her the cousin of Alison and the half sister of Spencer.² In the penultimate episode Mona confesses that she killed Charlotte by accident in the bell tower, the night Charlotte left the mental hospital.⁴

Mary Drake joins three families. She is the twin of Jessica and the mother of Charlotte, Spencer and Alex. Refinery29 reports that she murdered her twin sister.² In the penultimate episode Mary confesses to the police, which takes away the hold that A.D. had over the Liars.⁴

The chart draws two pairs of twins. Mary and Jessica are joined by a dotted line, because the series never shows their parents, and Spencer and Alex hang from one point under Peter and Mary, the sign of twins. Wren, who falls for Alex believing she is Spencer, is killed by her because he still knew her as Alex.³

A square is a man and a circle is a woman. A line between a couple with a line down to the children is a marriage, and a green dashed arrow marks an adoption. A cross marks a death, and a broken cross marks someone believed dead. Each family has its own ring, and the letter A at the corner marks each person once they are unmasked as A.

A, Big A and A.D. are drawn as dashed boxes with a question mark until their season, and then they merge into Mona, Charlotte and Alex. The dashed red lines from Peter to Jason and from Pastor Ted to Charlotte are fathers the families hid, and the words at each end of a line say what each side does at the season you choose.
