The Game of Thrones Family Tree: A Complete Guide to Major Houses and Key Relationships

The Game of Thrones family tree centers on the intertwined houses of Westeros, where marriage, inheritance, and power shape a complex relationship network. This relationship explainer maps the most important houses and connections, focusing on how lineage and political bonds drive the story. You will find a clear breakdown of major figures, their family ties, and the houses they represent. By clarifying parent–child and spousal links, this guide helps you track who is related to whom and why these relationships matter across the series.

Major Houses and Core Bloodlines

At the top of the Game of Thrones family tree lie several great houses, each with multi-generation lineages that define the politics of the Seven Kingdoms. Stark, Lannister, Baratheon, Targaryen, Greyjoy, and Tyrell form the central network of parent–child, sibling, and marital ties. Understanding these houses and their core members provides a durable scaffold for tracking the broader cast. The following sections isolate bloodlines, marriage connections, and succession links that recur across the series.

The Stark Lineage and Key Relationships

House Stark of Winterfell is defined by a multi-generational line with clear parent–child links and several strategic marriages into other houses. Eddard Stark and Catelyn Stark (née Tully) anchor the modern generation, anchoring a line that reaches back to ancient house founders. Their children represent a pivotal branch of the Stark tree. Beyond blood, alliances through marriage and fosterage extend their influence into other houses, shaping regional loyalties and conflicts.

  • Eddard Stark and Catelyn Stark (née Tully): married, parents to Robb, Sansa, Arya, Bran, and Rickon.
  • Robb Stark: married Talisa Maegyr, extending Stark connections into Essos.
  • Sansa Stark: married Tyrion Lannister (ceremony), later married Littlefinger; alliances shifted across seasons.
  • Arya Stark, Bran Stark, and Rickon Stark: their relationships to the broader political landscape evolve through mentors and found-family ties rather than direct marriage lines.

The Lannister and Baratheon Connection

House Lannister and House Baratheon are linked through both blood and marriage, forming a central strand of the family tree. The union of Tywin Lannister with Joanna Baratheon bound the houses, producing children who carry both surnames in their lineage. This connection illustrates how marriage serves as a tool for consolidating power. Subsequent marriages and offspring continue to weave Lannister and Baratheon interests together, despite periods of open conflict.

  • Tywin Lannister and Joanna Baratheon: married, producing Cersei, Jaime, and Tyrion.
  • Cersei Lannister: married Robert Baratheon, producing Joffrey, Myrcella, and Tommen.
  • Jaime Lannister: married sister Cersei Lannister, producing Joffrey, Myrcella, and Tommen in the show; dynamic with Tyrion differs in the books.
  • Tyrion Lannister: married Sansa Stark, later married Shae and eventually an Essosi noblewoman in the books; alliances and outcomes vary by medium.

The Targaryen Dragonblood and Marriages

House Targaryen maintains a distinct dragonblood identity, with a tradition of sibling marriage to preserve the bloodline in their origin story. In the main narrative, Daenerys Targaryen stands as the central figure, with her children and claimed lineage shaping political stakes. Marriages and potential matches are used to build alliances across continents, making the Targaryen tree a mix of consanguinity and strategic union.

  • Aerys II Targaryen and Elia Martell: married, producing Rhaegar, Viserys, and Princess Elia.
  • Rhaegar Targaryen: (married Elia Martell); in the show, his relationship with Lyanna Stark leads to Jon Snow’s parentage.
  • Daenerys Targaryen: key marriages include Drogo (Dothraki) and later claimants in the series; her lineage is central to her claim.

House Greyjoy and House Tyrell are connected through both marriage and shifting allegiances, reflecting how regional houses use unions to project power. These connections often intersect with the main Stark, Lannister, and Baratheon conflicts, influencing which banners are raised in battle and who controls key seats.

  • Balon Greyjoy and Alannys Harlaw: married, producing Yara, Theon, and Asha (in the books).
  • Margaery Tyrell: married Renly Baratheon, then Joffrey Baratheon, and later Tommen Baratheon, illustrating strategic layering of marriages.
  • Loras Tyrell: closely tied to Margaery, with relationships that influence Reach politics.

Bastardy, Fostering, and Non-Traditional Kinship

The Game of Thrones family tree is not only defined by legitimate lines; bastardy and fostering create additional, consequential relationships. Noble houses use these arrangements to bind households, secure alliances, or hide sensitive lineages. Recognizing these ties is essential for a complete picture of how power and identity intersect in Westeros.

  • Jon Snow: believed son of Ned Stark, later revealed to have Rhaegar Targaryen parentage; raised at Winterfell with Stark siblings.
  • Gendry Baratheon: Robert’s bastard, later legitimized; forms a connection to the broader Baratheon line.
  • The Sand Snakes: daughters of Oberyn Martell, operating with strong personal loyalties distinct from their noble house.

Succession, Marriage, and Political Stability

Succession rules and marriage strategy heavily influence stability across the Great Houses. Some houses favor male-preference succession, while others prioritize securing key marriages that promise military or economic support. These patterns recur throughout the series and can be summarized in a concise reference table for clarity.

Tracking Relationships Across Mediums

The Game of Thrones family tree shows meaningful variation between George R. R. Martin’s books and the television series, particularly around marriage, parentage, and the timing of certain unions. These divergences do not nullify the underlying relationships but do shift how certain lines are traced. Where the show accelerates or reorders events, the book lineage often retains more intermediate generations and explicit naming. Recognizing these differences helps you interpret claims about who is related to whom across mediums.

Using This Guide to Navigate the Series

You can use this relationship-focused family tree as a reference while watching or reading, especially during episodes or chapters with multiple overlapping scenes. Track key parent–child links and marriages by house to maintain clarity about succession and alliance shifts. When new characters are introduced, ask which house they belong to and how they are connected to known figures. This habit reduces confusion and supports accurate speculation about future narrative turns.

Common Questions About the Family Tree

  • Is Jon Snow part of the Stark family tree in the books? In the books, Jon’s lineage is tied to House Targaryen through Rhaegar, but his Stark upbringing creates a hybrid identity.
  • How does Sansa Stark’s marital path differ between books and show? Sansa’s book trajectory involves different marriage arrangements and agency; the show consolidates key marriages earlier.
  • Are the Sand Snakes included in the main family tree diagrams? They appear as Martell daughters with loyalties distinct from formal succession lines; their role varies by medium.

The Game of Thrones family tree functions as a living network of blood, marriage, and alliance that underpins the series’ political drama. By clarifying house structures, core parent–child links, and marriage connections, you can better understand character motives and future possibilities.
