Rhaenyra and Daemon married years later after both of their spouses died, and had three children, the last being stillborn. Their second son, Viserys II, is Daenerys' direct connection to Rhaenyra.
Technically, Rhaenyra is Daenerys's sixth great grandmother and Jon's seventh great grandmother. That also makes Daenerys and Jon the direct descendants of Daemon, Rhaenyra's uncle/second husband.
In the television series Game of Thrones, the Targaryen dynasty ends with Daenerys and her nephew, Rhaegar's youngest son Aegon, who was raised as Jon Snow.
Daenerys (Emilia Clarke) is the Mad King's daughter with his sister-wife Rhaella. She is the youngest of their three children, after Rhaegar – Jon Snow's father – and Viserys.
Rhaenyra is Daenerys' great-great-great-great-great-great-great grandmother (yes, that's seven “greats”). That means she's Jon Snow's (aka Aegon Targaryen's) eight-times great-grandmother since he's one generation after Aunt Dany, despite the two being the same age.
Finally, we reach Daenerys Targaryen and Jon Snow
Aerys, of course, is the father of Daenerys Targaryen as well as her older brother Viserys, who shares a name with the two other guys named Viserys we meet on House of the Dragon. Aerys was also the father of Rhaegar Targaryen, who was born on the day Summerhall burned.
King Viserys, Rhaenyra's father, has turned a blind eye to the lineage of his grandsons. When Queen Alicent presses him on the matter, Viserys simply chalks up the children's physical variations to the spontaneity and uncertainty of nature.
Game of Thrones' Baratheons are also direct descendants of House of the Dragon's Rhaenyra and Daemon Targaryen. Robert's grandmother was Rhaelle Targaryen, the great-great-great granddaughter of Rhaenyra and Daemon's son King Viserys II Targaryen.
On his deathbed, Viserys dreamt of one of his heirs wearing the Conqueror's Crown—the crown that once belonged to Aegon. By naming her first born son Aegon, it shows that Rhaenyra intends to fight to fulfill the prophecy in the same way that her father did.
Joffrey Baratheon spoils Rhaenyra Targaryen's fate on Game of Thrones. As Joffrey tells us, eventually, Rhaenyra's half-brother Aegon Targaryen will feed her to his dragon Sunfyre. She dies as her son, Aegon III, watches. That's the bullet point version.
Aegon III, aka Aegon the Younger: Rhaenyra and Daemon's first child together.
After the conclusion of the Great War and the Battle of King's Landing and following the assassination of Queen Daenerys Targaryen. With Valerie Targaryen who is still adjusting to finding out she is the twin sister to Jon Snow as well as the secret daughter of Rhaegar Targaryen and Lyanna Stark.
Princess Rhaenyra is Daenerys' distant ancestor in the Targaryen family tree. Princess Rhaenyra and Daenerys are distant relatives, living 200 years and about eight generations apart, as this thorough Targaryen family tree demonstrates.
Rhaenyra was a dragonrider whose mount was Syrax. Her claim to the Iron Throne was challenged by her younger half-brother, Aegon II Targaryen, sparking the civil war known as the Dance of the Dragons.
Traditionally, House Stark has always been known for keeping their promises; when Rhaenyra is named Viserys I's heir, Rickon Stark (David Hounslow) pledges fealty to her. In addition to visiting the Eerie, Jacaerys is sent by his mother to Winterfell to ensure the Starks' loyalty still stands.
Rhaenyra Targaryen, the rightful heir to the Iron Throne, briefly considered bending the knee to her half-brother King Aegon II in the Season 1 finale of House of the Dragon, thus sparing the citizens of Westeros years of dragon fire and bloodshed.
Later, when Rhaenyra marries her uncle Daemon, Aegon was about 13 years old and becomes deeply offended (as his mother) when his sister names a son also as Aegon. Aegon II marries his sister, Haelaena and they have three children: Jaehaerys and Jaeharera (twins), and Maelor.
Aegon Targaryen, also known as 'Aegon the Elder', and later, 'the Usurper', was a rebel Targaryen king, unlawfully succeeding his father, Viserys I Targaryen, as Lord of the Seven Kingdoms. His ascent was disputed by his older half-sister, Princess Rhaenyra Targaryen, who had been their father's designated heir.
9 Princess Rhaenyra Targaryen Is Jon Snow's Seventh Great-Grandmother. Princess Rhaenyra Targaryen is one of the most important characters in House of the Dragon. After her uncle Daemon was banished from King's Landing, Rhaenyra was named heir to the Iron Throne by her father.
Background. Joffrey is the youngest son of Rhaenyra Targaryen and Laenor Velaryon. He has two older brothers, Prince Jacaerys Velaryon and Prince Lucerys Velaryon and is presently second-in-line to succeed to the Iron Throne.
Prince Joffrey Velaryon, also known as Joff, was the thirdborn son of Princess Rhaenyra Targaryen and her first husband, Ser Laenor Velaryon.
According to the accounts of Septon Eustace, prior to her turning sixteen, Rhaenyra lost her virginity to her uncle, Prince Daemon, after he seduced her.
It isn't explicitly stated in the show, but because we learn after episode six that all three boys have dark brown hair — and despite Rhaenyra and Laenor's matching blond color — it has been strongly implied that they are actually the children of Ser Harwin Strong, the Lord Commander of the City Watch.
In George R.R. Martin's fictitious history of the Targaryen family, we learn that Rhaenyra does eventually have children with her uncle Daemon: two boys named Viserys II and Aegon III, both of whom eventually become king.
