Overview of the Game of Thrones Family Tree
The Game of Thrones family tree centers on rival noble houses competing for control of Westeros. The largest houses include Stark, Lannister, Targaryen, Baratheon, and Martell, each with distinct lineages and claims. The series maps complex blood ties, marriages, and betrayals that shape political alliances and wars across the continents of Westeros and Essos. HBO's official Game of Thrones companion materials and related pages provide detailed house summaries and relationship charts. HBO Game of Thrones
In the narrative, the family tree drives key plot points such as the fall of the Targaryen dynasty, Robert's Rebellion, and the War of the Five Kings. Characters like Jon Snow, Daenerys Targaryen, Tyrion Lannister, and Sansa Stark trace their legitimacy and claims through documented parentage and marriage. The show draws on George R.R. Martin's A Song of Ice and Fire series, which expands the family tree with thousands of named characters and intricate genealogies. A Song of Ice and Fire on Wikipedia
Major Houses and Their Lineages
House Stark
House Stark rules the North from Winterfell, with a lineage tracing back thousands of years in the Game of Thrones family tree. Key members include Eddard Stark, his children Robb, Sansa, Arya, Bran, and Rickon, and his wife Catelyn Tully. The Stark sigil is a direwolf, and their words are "Winter Is Coming," reflecting their role as wardens of the North. Forbes on House Stark
House Lannister
House Lannister controls the Westerlands and is one of the wealthiest families in the Game of Thrones family tree. Key figures include Tywin Lannister, his children Cersei, Jaime, and Tyrion, and grandson Joffrey Baratheon, who is legally a Lannister through Cersei's marriage. The Lannister sigil is a golden lion on crimson, and their words are "Hear Me Roar." Their vast gold mines at Casterly Rock fund much of the crown's debt and military campaigns.

Claims to the Iron Throne and Key Marriages
Targaryen and Baratheon Lines
The Game of Thrones family tree shows the Targaryens as the original rulers of Westeros, with Daenerys Targaryen as the last surviving heir after Robert Baratheon's rebellion. Robert married Cersei Lannister, linking the Baratheon and Lannister lines and producing Joffrey, Myrcella, and Tommen, who all sit on the Iron Throne in succession. HBO Game of Thrones
Marriages in the Game of Thrones family tree often serve as political tools, such as the union of Jon Snow and Daenerys Targaryen, which connects the Stark and Targaryen lines. The Red Wedding eliminates Robb Stark and his key allies, reshaping the balance of power and leaving Sansa Stark as a key claimant in the North
