Summary
House of the Dragon’s Daemon Targaryen is related toGame of Thrones’ Daenerys, with his and Rhaenyra’s lineage directly connecting to the Mother of Dragons. As one of the main characters inA Song of Ice and Fire, Daenerys is arguably the most recognizable Targaryen from the world created by George R.R. Martin. WhereasGame of Throneswas set in a time when most but not all Targaryens were gone,House of the Dragonsees the “House of the Dragon” at the height of their power. TheHouse Targaryen prequelstarts 197 years beforeGame of Thrones.
TheDance of the Dragons, the Targaryen civil war covered inHouse of the Dragon, ended in 131 AC. Daenerys Targaryen was born in 284 AC in the books, although she and most of the characters were aged up in the HBO adaptation. Regardless, almost 200 years separate the main events ofHouse of the DragonandGame of Thrones. WhileHouse Targaryen was never the same after the Dance, it continued to rule Westeros for a couple of more generations before Robert Baratheon’s rebellion put an end to the dynasty that began with Aegon the Conqueror.

Both Daemon andRhaenyra Targaryen were killed during the Dance of the Dragons. Daemon died first, at the Battle Above the God’s Eye against Aemond Targaryen. While Rhaenyra sat on the Iron Throne for a while, she had to flee the capital and fall into a trap in Dragonstone set up by Aegon II. Team Green technically won the war onceAegon II killed Rhaenyraand returned to the throne, but the line of succession would change again shortly after. Aegon II was poisoned by someone in the court, leaving Corlys Velaryon and other powerful lords to choose a new ruler.
Daemon is Jon Snow’s seventh great-grandfather in HBO’sGame of Thronesuniverse, as Jon is the son of Rhaegar Targaryen and Lyanna Stark.

Lord Corlys supported the claim of a different Aegon – Rhaenyra and Daemon’s oldest son. Rhaenyra and Daemon had two children, but at the end of the war, it was believed that the youngest one, Viserys, had died. Aegon was safe, though, and despite his young age, he was chosen as the new king. However, Rhaenyra’s lineage did not continue through Aegon III. He and his male sons died without heirs, after which Viserys II was crowned.Viserys II started a lineage that would continue for hundreds of years until Aerys II Targaryenand his children: Rhaegar, Viserys, and Daenerys.

Aerys II’s daughter
Viserys II’s line was more stable than the previous one. His son, Aegon VI Targaryen, was considered the worst Aegon but left an heir, Daeron II. Daeron’s successor was Maekar; Maekar’s heir was Aegon V; Aegon’s son was Jaehaerys II, and Jaehaerys II’s heir was Aerys II Targaryen. The last of the Targaryen kings before Robert’s rebellion,Aerys was the father of Viserys and Daenerys. In other words,House of the Dragon’s Daemon and Rhaenyra are the sixth great-grandparents of Daenerys Targaryen. They are also the seventh great-grandparents of Jon Snow, born Aegon Targaryen inGame of Thrones.
