Who's who in 'House of the Dragon': The Targaryen family tree (2024)

Once upon a time in the fantasy land of Westeros, a clan of fireproof, dragon-riding blondes took over the Seven Kingdoms and committed a shocking amount of direct sibling incest. They were House Targaryen, and they ruled for centuries until one of their descendants fumbled the bag and let Robert Baratheon usurp the throne. Then came the story of Game of Thrones… and we all know how that turned out.

House of the Dragon turns back the clock to the weird old days of Targaryen rule — more specifically, the period before and during a civil war called the Dance of the Dragons. Needless to say, there are a lot more Targaryens around in this time than there were during Thrones, and remembering who’s related to who is a lot harder in this show. Don’t worry though, we got you. Not only do we have what the Targaryen family tree looked like at the start of Season 1, but also we've got the update to keep things straight after the Episode 6 time jump.

This is the family tree as it exists at the start of House of the Dragon. Only the most relevant children in each generation are included, since fully outlining the dozens of rogue cousins, usurpers, minor monarchs, and temporary heirs would literally take longer than just watching the first episode.

Aegon “The Conqueror” Targaryen and Rhaenys Targaryen

If there’s one dead Targaryen the people on Game of Thrones mentioned most (besides the Mad King and Rhaegar), it’s Aegon “The Conqueror.” He founded the royal line by taking over the majority of the Seven Kingdoms and uniting them under his rule. Aegon also married both of his sisters, Rhaenys and Visenya, according to the extremely nasty family tradition of keeping their bloodline “pure” — a word which here means “dragon-riding and potentially insane.”

Incest: Siblings.

Relevant children: Aenys Targaryen

Aenys Targaryen and Alyssa Velaryon

First of all, it’s pronounced “Ennis.” Be nice. His wife Alyssa was a Velaryon, so the Velaryon family has had skin in the game (of thrones) since the foundation of the Targaryen dynasty.

Incest: First cousins, which is the genetic equivalent of a rando off the street for this family.

Relevant children: Jaehaerys Targaryen and Alysanne Targaryen

Jaehaerys “The Old King” Targaryen and Alysanne Targaryen

As far as sibling incest goes, these two are actually…kind of sweet? They were supposed to be married off to other families but ran away to elope together because they loved each other from childhood. (Yeah, nope. Still bad.)

Jaehaerys and Alysanne ruled well together and their reign was a golden age for the Targaryens. They also had tons of kids but only four of them really mattered in the long term.

Incest: Siblings.

Relevant children: Aemon, Baelon, Alyssa, and Daella — in that birth order.

Aemon Targaryen and Jocelyn Baratheon (not pictured)

Aemon was the firstborn surviving son and heir of Jaehaerys I Targaryen. He married a Baratheon, which seems like it would be not super incest-y, but that Baratheon was also his aunt. Aemon died before his father, passing the role of heir down to his younger brother Baelon.

Incest: Whatever a guy marrying his parents’ shared half-sister is.

Relevant children: Rhaenys Targaryen

Baelon Targaryen and Alyssa Targaryen

Ah, so we’re back to marrying our siblings. Baelon had two sons with his sister Alyssa and became the new heir after his brother Aemon died. Then he died, leaving Jaehaerys and Alysanne with exactly zero eligible sons to inherit the throne directly.

Incest: Siblings. Again.

Relevant children: Viserys and Daemon Targaryen

Daella Targaryen and Roderick Arryn (not pictured)

Daella Targaryen married young and unfortunately died giving birth to her first and only daughter, Aemma.

Incest: Absolutely none, which is quite a shock.

Relevant children: Aemma Arryn

Rhaenys Targaryen and Corlys Velaryon

Rhaenys is the firstborn child of Aemon Targaryen and eldest granddaughter of Jaehaerys and Alysanne. She’s married to Corlys “The Sea Snake” Velaryon in a love match that consolidates a ton of the realm’s wealth and power into one badass mega-family.

However, her claim to the Iron Throne (as well as the claim of her son Laenor) was passed over in favor of her younger cousin Viserys. Was that a bad move? Tune in to find out!

Incest: Super distant cousins, to the point where it’s a wash.

Relevant children: Laenor and Laena Velaryon (not pictured, they’re important later)

Viserys Targaryen and Aemma Arryn

The king and queen at the start of House of the Dragon are Viserys and Aemma, the children of Baelon and Daella Targaryen, respectively. They have one daughter, Rhaenyra, and hope to have a son, mainly because in the absence of a son the throne might pass to Viserys’ brother Daemon.

Now, to bring this full circle: Remember the part about Targaryen blood purity meaning “dragon-riding and potentially insane?” That’s Daemon to a T. And the T is for Targaryen.

Incest: First cousins.

Relevant children: Rhaenyra Targaryen

The Targaryen Family Tree from Episode 6 onward

How’s it going? Everybody having fun? Is everyone keeping the dragon names straight? Are we agreed on who the MVPs are of each episode? Good.

Of course, the moment everyone gets comfortable with how things work in the Red Keep, House of the Dragon throws a curveball and jumps ahead 10-ish years to when Rhaenyra, Alicent, and Daemon all have children of their own. Just to make sure everyone’s caught up on all the new Targaryens, Velaryons, and other strong (ahem) contenders for our attention, here’s what the family tree looks like as of Episode 6 of House of the Dragon.

And here's how the Targaryen's branches are faring:

King Viserys Targaryen and Aemma Arryn [DECEASED]

King Viserys and Aemma Arryn were a lovely match —up until the point he allowed his maesters to perform a C-section without her consent. Baelon, the son Aemma died to deliver, only survived his mother for a few more hours, earning the mocking moniker “Heir for a Day” from Viserys’ younger brother Daemon.

After that, Viserys named his daughter Rhaenyra his absolute heir, rather than pass the throne to Daemon.

Incest: First Cousins

Relevant Children: Rhaenyra Targaryen, Baelon Targaryen [DECEASED]

King Viserys Targaryen and Alicent Hightower

After the death of his beloved Queen Aemma, Viserys was pressured into taking another wife and chose Alicent Hightower, his daughter’s best friend and daughter of his Hand, Otto Hightower. Nothing says “friendship killer” like your bestie marrying your dad, right? Yikes!

Incest: None, to Viserys’ credit. That’s all he gets credit for.

Relevant Children: Aegon, Helaena, Aemond, and Daeron Targaryen [Not born yet]

Corlys Velaryon and Rhaenys Targaryen

Even though Rhaenys’ claim to the throne was passed over for her cousin Viserys, Corlys and Rhaenys have hella status without actually having to rule the kingdom. They’re powerful, they’re rich, and their kids have royal blood, making their bloodline ideal to marry back into the Targaryen family.

Incest: Distant cousins

Relevant Children: Laenor and Laena Velaryon

Daemon Targaryen and Laena Velaryon

After the (ahem) tragic death of his first wife Rhea Royce, Daemon Targaryen married Laena Velaryon, the beautiful daughter of his first cousin Rhaenys. Due to Daemon’s um, misbehavior at court, they were forced into exile in Pentos, where they live with their twin daughters and fly around on their cool dragons Caraxes and Vhagar.

Incest: First cousins once removed

Relevant Children: Baela and Rhaena Targaryen

Rhaenyra Targaryen and Laenor Velaryon

Rhaenyra’s marriage to Laenor Velaryon was sort of a given, considering her unique status as a princess and future ruling queen. Only someone with the blood of the dragon would do for her, and Laenor was right there looking like a completely uninterested — I mean, clearly devoted — snack.

Incest: Second Cousins

Relevant Children: Officially? Jacaerys, Lucerys, and Joffrey Velaryon.

Rhaenyra Targaryen and Ser Harwin “Breakbones” Strong

Yeah, so Rhaenyra wasn’t exactly Laenor’s type. He wasn’t hers either. When her children were born looking absolutely nothing like their father, she insisted that they were Laenor’s legitimate sons…all while having a very close relationship with Ser Harwin Strong, the brunette son of the King’s Master of Laws. And hey, would you look at that? If you squint her kids do kind of look like…uh. Never mind.

Incest: None

Relevant Children. Jacaerys, Lucerys, and Joffrey “Velaryon”
