House Stark Family Tree
The House Stark family tree traces back to the Age of Heroes, with Bran the Builder founding Winterfell and establishing the Stark lineage as Kings in the North. The main branch includes Eddard Stark, his children Robb, Sansa, Arya, Bran, and Rickon, plus nephew Jon Snow, whose true parentage as Rhaegar Targaryen and Lyanna Stark's son reshapes the entire family tree for Game of Thrones. Forbes details the full Stark lineage and key marriages.
The Stark family tree extends through cadet branches like the Karstarks and Umber vassals, with alliances forged through marriages such as Catelyn Tully and Edmure Tully connecting the North to the Riverlands. The crypts of Winterfell hold the tombs of past Kings in the North, and the direwolf sigil remains the defining symbol of the house's honor, duty, and survival through wars against the Boltons, wildlings, and the White Walkers.
House Targaryen Family Tree
The House Targaryen family tree centers on a dynasty of dragonlords who conquered Westeros roughly 300 years before the events of Game of Thrones, with Aegon the Conqueror, his sisters Visenya and Rhaenys, and their dragons forging the Iron Throne. The main branch includes Aerys II, his children Rhaegar, Viserys, and Daenerys, plus key cadet branches like the Kingsguard and marriages that link the Targaryens to the Baratheons and Martells.
The Targaryen family tree explains the core conflict of the series, as Rhaegar's son Aegon becomes a focal point for claims to the Iron Throne, while Daenerys's marriage to Khal Drogo and her dragons mark her return to Westeros as a claimant. HBO's official Game of Thrones site provides a visual Targaryen family tree and character guides. The family's practice of incestuous marriages preserved pure bloodlines but also amplified the traits of madness and fire that define key figures like Aerys and Daenerys.
House Lannister and Great Houses Interconnections
The House Lannister family tree connects to the Baratheons through Jaime, Cersei, and Tyrion, with Cersei's marriage to Robert Baratheon making her queen and tying the Lannisters directly to the Iron Throne. The Lannister sigil of the lion, their wealth from the Casterly Rock gold mines, and their motto "Hear Me Roar" reflect a house defined by ambition, cunning, and ruthless pragmatism across generations.
The Great Houses family tree weaves together the Starks, Targaryens, Lannisters, Tyrells, Martells, Greyjoys, and Arryns through centuries of marriages, wars, and betrayals that shape the political landscape of Westeros. A Semafor guide maps the Great Houses and their alliances. Britannica summarizes the major houses and their roles in the series. These interconnected family trees explain why the War of the Five Kings erupts and how characters like Jon Snow, Daenerys Targaryen, and the Lannister siblings collide over the Iron Throne.
