Where the Blue Prince family tree is hidden
The Blue Prince family tree is never handed to the player in one place. You play the heir of Mount Holly, a manor of 45 rooms that shift as you go, and the official store page promises a story of blackmail, political intrigue and the disappearance of a local children’s book author.1 The family behind that story is pieced together from a will, photographs, letters and one drawing on a cellar wall.
Start with the will. The official announcement of the game names the dead baron and the heir and says how they are related, so the first two names on the chart are known from the start.2
Then look at the photographs. Game Rant points to a photo of the young Simon with his mother and father, and to the voice of Simon’s mother heard in the game.6 Kotaku adds that Simon finds the children’s book his mother wrote for him and clues to her heritage.7
The largest clue is the drawing of the family on the wall of the Root Cellar, a green room among the Outer Rooms. The community wiki records that its top right corner is torn away and that one name at the bottom root is faint, with a further phrase beside it that only the Magnifying Glass shows.89 Read the tree with the will in mind and the heir’s place on it follows.
The last clue is a letter in another language, addressed to Clara by her mother. Game Rant reads it after a translation, and its reading changes what the family is.6 If you want to solve the tree yourself, stop here. Everything below this section gives the answer.
Spoilers, the Blue Prince family tree solved
This section and every section after it give away the family puzzle of Blue Prince. The person the chart is about is Simon P. Jones, the player character. His grand-uncle, Herbert S. Sinclair, has recently died, and Simon is the sole beneficiary of the Sinclair estate at Mount Holly.2 Raw Fury’s second development post calls Mount Holly the esteemed domain of your great uncle.3
Nintendo Life names Herbert as the baron of Reddington’s Mount Holly Estate and says his will leaves the estate, its grounds and his title to his grandnephew, Simon.4 Game Rant gives the heir’s full name as Simon P. Jones.5 The chart draws this link twice. A dotted blue arrow labelled Leaves him the estate runs from Herbert to Simon from the first story point, and from the second point the family lines show how the grand-uncle and the heir are joined.
Herbert and Simon Sinclair, the two brothers
A grand-uncle is the brother of a grandparent, and Game Rant names the grandparent. The protagonist’s grandfather is the first Simon Sinclair, Herbert’s brother.6 That one sentence solves the top half of the Sinclair side, and it is the only press source that states it, so the table below marks it as resting on one source. The community wiki gives the same brothers, with Simon as the younger.10
Their parents come from the Root Cellar tree as the community wiki reads it. The wiki names them as Tomas Sinclair, the former baron, and Baroness Auravei, and makes them the great-grandparents of the heir.1011 No official post or press article opened for this page names either of them, so the chart draws their lines from the Root Cellar point and the table marks them as from the community wiki.
The chart gives Herbert the cross of a death before the game begins, as the official post states.2 The wiki also gives Simon Sinclair as dead before the game, and the chart marks his death on the wiki’s word.10
Clara Epsen and the second family on the tree
Game Rant says that Clara married the first Simon Sinclair and so married into Herbert Sinclair’s family.6 Kotaku quotes a note left by Lady Clara and gives her no other role.7 The community wiki names her Lady Clara Epsen and dates the marriage to 1951 from the tree, and the chart writes that year on the marriage line.12
Clara’s side of the tree rests on the community wiki alone. It names her parents as William Epsen and Ashlynn, Lady Ashlynn Epsen, and her brother as Lionel Epsen, who left the family estate after his father’s death and never came to Mount Holly to claim his sister’s diary, which Herbert’s will left to him.1213 The tree gives Clara a death in 1983, and the chart marks her death on the wiki’s word.9 The chart draws the Epsens inside a green outline labelled House Epsen, a name the letter to Clara itself uses.6
Mary Jones, the missing mother at the centre of the tree
Mary is Simon’s mother, as Game Rant and Kotaku both state.67 Kotaku follows her through the game, and finds that she fled Orinda Ares and never reappears, with no answer as to whether she is alive or dead.7 The chart gives her no cross of death, because her fate is left open.
Mary is the daughter of Simon Sinclair and Clara. Game Rant gets there in two steps, making Simon Sinclair the protagonist’s grandfather and Mary a descendant of Clara’s mother’s line, and the community wiki states it outright.614 She was born Mary Matthew Epsen, with her mother’s surname, which fits the custom Game Rant describes of passing down the mother’s name rather than the father’s.146 The wiki adds that she wrote children’s books as Marion Marigold.14
Simon’s father appears in the press only as the man in the family photo.6 The community wiki names him as Daniel Jones and makes Mary and Daniel the parents of Simon P. Jones.15 The chart draws him with that note.
The wiki gives two birth years for Mary, 1954 from the tree and 1958 in its own account of her, so the chart shows no birth years at all.914
The letter to Clara and the royal line
The last clue changes the meaning of the tree. Game Rant reads the letter to Clara from her mother, written when Clara married into the Sinclair family, as proof that Clara’s mother was of the original Orindia royal bloodline. Mary, and therefore Simon, descends from that royal family.6 The translated letter tells its reader that they are not of House Sinclair nor House Epsen.6
Game Rant does not name Clara’s mother, and the wiki names her as Ashlynn, so the chart adds the role Royal line to Ashlynn from the third story point and the role Royal heir to Simon.612 Game Rant’s reading rests on a rough translation of the letter, and the page gives it as Game Rant’s reading.

How to read this Blue Prince family tree
A square is a man and a circle is a woman, and Simon carries the double outline of the person the chart is about. A horizontal line between two symbols is a marriage, and lines down from it lead to the children. A cross is a death. Tomas, Auravei, Lionel and Mary carry no cross, because the sources do not say whether they are alive.
The blue outline gathers House Sinclair and the green outline House Epsen, each with its letter on the symbols. Mary, Daniel and Simon stand outside both outlines, as the letter to Clara puts the heir outside both houses.
To keep your own notes on the puzzle, open this chart in the editor and add what you find, or start from the other story charts. The symbols are set out in the genogram symbols.
