Key Targaryen Relationships in House of the Dragon
This relationship guide focuses on the main Targaryen lineage featured in House of the Dragon, clarifying parent–child links, marriages, and succession implications. It explains how each major figure connects to Viserys I, Aegon II, and Rhaenyra, and why these bonds matter for legitimacy and inheritance under Westerosi law. The aim is to clarify the family structure without speculation, using only aired details and established lore that remain consistent in the show’s ongoing timeline.
Viserys I Targaryen and His Immediate Family
King Viserys I Targaryen is the dynastic anchor in the first season. His confirmed children shape the present conflict, and his marriages influence succession perception. Understanding his lineage is essential to tracing the broader family tree.
Children of Viserys I and Aemma Arryn
- Princess Rhaenyra Targaryen: Only surviving child of Viserys and Aemma, named heir following the stillbirth of her older brother. She is the central figure around which rival claims coalesce.
- Unnamed son: Born stillborn late in Viserys I’s first reign; his loss drives the decision to present Rhaenyra as the next in line.
Later Children and the Claimant Landscape
After Aemma’s death, Viserys married Alicent Hightower, producing sons who shift power dynamics. Their births create a direct challenge to Rhaenyra’s previously secure position.
- Aegon II Targaryen: Firstborn son of Viserys and Alicent, later proclaimed king by the greens. His claim contrasts with Rhaenyra’s supporters.
- Aemond Targaryen: Younger son of Viserys and Alicent, positioned as a key military figure in the growing conflict.
- Daemon Targaryen: Brother of Viserys I and patriarch of the exiled cadet branch. His actions and alliances indirectly shape the succession struggle.
Rhaenyra Targaryen and Her Lineage
As Viserys’s designated heir, Rhaenyra’s lineage determines potential heirs and future claims. Her choices in spouse and offspring carry dynastic weight within the show’s politics.
Marriages and Offspring

- Baela Velaryon: Daughter of Laenor and Rhaenyra, positioned as another claimant descendant.
- Roona Velaryon: Daughter of Laenor and Rhaenyra, representing further generational continuity.
- Harwin Strong: Rumored biological father of some children, adding uncertainty to lineage that remains narratively significant.
- Daemon Targaryen: Second husband in many storylines, father of her sons and continuation of her political standing.
- Aegon the Elder: Son of Rhaenyra and Daemon, later known as Aegon III, pivotal in post-civil-war succession.
- Viserys Targaryen: Another son of Rhaenyra and Daemon, reinforcing the continuity of her line.
- Baela Targaryen: Daughter of Rhaenyra and Daemon, linked to future dynastic plots.
- Jacaerys Velaryon: Son of Rhaenyra and Laenor, influential in council and succession debates.
