House Stark and the Northern Lineage
The Game of Thrones season 4 family tree places House Stark at the center of the Northern power structure, with Eddard Stark executed in season 1 and his children scattered across the realm. Robb Stark was declared King in the North and killed at the Red Wedding, leaving Sansa, Arya, Bran, and Rickon as surviving Stark heirs with contested claims. Bran Stark, now the Three-Eyed Raven, holds a supernatural claim rather than a traditional military one, while Jon Snow is later revealed as Rhaegar Targaryen's son, complicating the Stark-Targaryen lineage.

Sansa Stark marries Tyrion Lannister in King's Landing as a political move, while Arya trains as a Faceless Man in Braavos, and Rickon is separated from the group and later captured by Ramsay Bolton. The season 4 family tree shows the Starks losing direct control of Winterfell to the Boltons, with Roose Bolton ruling as Warden of the North under the Iron Throne's nominal authority.

House Lannister, Tyrell, and the Iron Throne
House Lannister dominates the Game of Thrones season 4 family tree through Cersei Lannister, who becomes Queen Regent after King Joffrey Baratheon's death and rules with Tywin Lannister as Hand of the King. The Lannister-Targaryen connection runs through Cersei's marriage to Robert Baratheon, whose claim derived from his own Targaryen grandmother, while Joffrey, Tommen, and Myrcella are legally Robert's children but biologically Lannister. Forbes breakdown of Lannister succession.
House Tyrell, led by Margaery Tyrell, allies with the Lannisters through strategic marriages, with Margaery marrying Joffrey, then Tommen, consolidating Tyrell influence at court. The season 4 family tree shows the Tyrells controlling the Reach, the largest grain supply in Westeros, giving them economic leverage over the Iron Throne. Forbes on Tyrell political strategy.
House Targaryen, Baratheon, and the Claimants
The Game of Thrones season 4 family tree identifies Daenerys Targaryen as the last surviving Targaryen heir, with her claim based on Viserys I's line and her marriage to Khal Drogo producing a son, Rhaego, who dies in season 4. The Baratheon claim fractures after Robert's death, with Stannis Baratheon and Renly Baratheon both asserting legitimacy as Robert's brothers, though Stannis is the senior heir.
