In the world of House of the Dragon, few figures carry as much political and personal weight as Rhaenyra Targaryen, the declared heir of King Viserys I. Her children stand at the center of the succession crisis that tears the realm apart, their parentage a source of both quiet scandal and open conflict. Understanding who fathered them and how they fit into the wider Targaryen lineage is essential to grasping the stakes of the Dance of the Dragons.
Rhaenyra’s story is one of two marriages and six children in total. The first three sons were born during her union with Laenor Velaryon, while the later three came from her marriage to her uncle, Prince Daemon Targaryen. Their mixed heritage and contested legitimacy helped fuel the rivalry between the Blacks and the Greens, shaping the fate of the Iron Throne itself.

The Sons of the First Marriage
Rhaenyra Targaryen’s marriage to Laenor Velaryon, heir to Driftmark, was a political arrangement that both parties approached with clear eyes. Laenor preferred the company of men, and the couple reached an understanding that allowed each to seek fulfillment elsewhere. The three boys who resulted—Jacaerys, Lucerys, and Joffrey Velaryon—were officially presented as Laenor’s sons and given the Velaryon name. In reality, their biological father was widely understood to be Ser Harwin Strong, the powerful captain of the City Watch and Rhaenyra’s longtime lover.
The children’s dark hair and features, so different from the silver-haired Valyrian look of both Rhaenyra and Laenor, made the truth an open secret at court. Queen Alicent and her faction used the boys’ appearance as a weapon, questioning their right to inherit. Despite the whispers, King Viserys continued to treat them as his grandsons and Rhaenyra’s legitimate heirs. Jacaerys, the eldest, was raised as the future king. Lucerys was named heir to Driftmark. Joffrey, the youngest of the three, completed the set of Strong-blooded princes who carried the Velaryon name in public while their true parentage remained a private truth between their mother and her lover.
Children with Daemon and the Wider Family Tree
After Laenor’s departure from the story, Rhaenyra Targaryen married her uncle Daemon, strengthening the Black claim through both blood and alliance. Together they had three children of undisputed Targaryen parentage: Aegon, later known as Aegon the Younger or Aegon III; Viserys, who would become Viserys II; and a daughter, Visenya, who was stillborn. These sons inherited the classic silver-gold hair and violet eyes of the dragonlords, leaving no room for the kind of doubt that surrounded their older half-brothers. Through this second marriage Rhaenyra also became stepmother to Daemon’s daughters from his previous union with Laena Velaryon—Baela and Rhaena—further intertwining the branches of the family.

Rhaenyra herself was the only surviving child of Viserys I and his first wife, Aemma Arryn. Her half-siblings by Alicent Hightower—Aegon II, Helaena, Aemond, and Daeron—formed the rival Green faction. The resulting family tree is dense with overlapping bloodlines: the Velaryon connection through the first marriage, the pure Targaryen line through Daemon, and the step-daughters who bridged both houses. In the end, it was Rhaenyra’s younger sons by Daemon who survived the civil war and continued the dynasty, while the older boys paid a heavy price for the throne their mother claimed.
