One of the biggest, most confusing aspects of the A Song of Ice And Fire universe is how everyone is related to each other. And when it comes to House Targaryen, aka the Dragon House which has a tendency to marry their own sisters? It gets even more confusing. Spoilers past this point but on HBO‘s A Knight of the Seven Kingdoms Episode 2, titled “Hard Salt Beef,” we met several new Targaryens. And then on Episode 3 “The Squire” we met another one. And then in Episode 4 “Seven” we met another one. But how do they connect to other iconic characters from Game of Thrones and House of the Dragon?
Well, I’ll tell you, I will. We’re not going to run down the entire Targaryen Family Tree because we’d be here all night. But I will break down who the new (at least to TV) Targaryens are we’ve met so far, as well as how they connect back to other, known characters. Ready? Let’s get into it.
Actually, one more note: we’re not going to talk too many future spoilers here… There are things that happen to characters we’ve met on the show already that will happen by season’s end. They’re a matter of record — George R.R. Martin’s novellas have been around for years, and this thing called Wikipedia exists — but as is, we’re going to concentrate on the characters know and what we know about them so far, as of AKotSK Season 1, Episode 4. Cool? Cool.
Note: This article has been updated on February 7, 2026 to include information through Episode 4, “Seven.”
Prince Baelor “Breakspear” Targaryen (Bertie Carvel)
Baelor is the Prince of Dragonstone, and the second-in-line to the Iron Throne after his father, Daeron Targaryen II. He is currently also Hand to the King, and father to two princes (yeah, what I said now): Prince Valarr, who we’ll talk about in a second, and Prince Matarys.
As for descendants of Baelor’s bloodline that we might have seen on Game of Thrones — important to note, this takes place about 100 years before the OG series — the answer is “none.” Valarr had two stillborn sons with a woman named Kiera of Tyrosh, but that’s it.
Working backwards though, Baelor’s great-great grandfather and grandmother are Daemon Targaryen (Matt Smith) and Rhaenyra Targaryen (Emma D’Arcy), respectively. Daemon and Rhaenyra had a bunch of kids together, but the most important one to Baelor is his grandfather, Viserys Targaryen. So far, this Viserys is still a little kid as of House of the Dragon Season 2, one of the children that Rhaenyra sent to the Eyrie for their protection. At the end of that season, Little Viserys went with his siblings to go live with Reggio Haratis in Pentos.
Prince Maekar Targaryen (Sam Spruell)
Maeker is the brother of Baelor, and despite the general weird knot that is the Targaryen bloodline, he’s actually on the same branch as his bro bro. Specifically, Daemon and Rhaenyra are also his great-great grandfather and grandmother, and Viserys is his grandfather. Listen, this isn’t always true with Targaryens, okay?
He also has a ton of kids, some of whom we meet or are mentioned on AKofSK: Daeron, Aerion, Aemon, Daella, Aegon, and Rhae. While we won’t explain all of these for, uh, reasons, we will mention that Aemon is character you know pretty well from Game of Thrones… He’s Maester Aemon (Peter Vaughn), though you likely know him better as the Maester of Castle Black, aka the old man Jon Snow (Kit Harington) befriends at The Wall.
But wait, that’s not all! Maeker’s son Aegon sired a number of children himself. One of them, Rhaelle, married Ormund Baratheon and gave birth to Steffon Baratheon, the father of Robert Baratheon, Stannis Baratheon, and Renly Baratheon, all crucial characters to Game of Thrones. Stannis is the father of Princess Shireen, and technically Robert is the father of Joffrey, Myrcella, and Tommen. But come on, we all know those are Jaime Lannister’s kids.
There’s more! Aegon, I don’t think I mentioned, married his sister and had two more kids, Jaeherys and Shaera, who married each other, and then had two kids themselves Aerys and Rhaella, who also married each other. And they had a number of kids themselves, but the most important to our purposes are Prince Rhaegar and his sister… Daenerys (Emilia Clarke). The latter you likely know. And the former? He’s the father of the one and only Jon Snow.
So while Maekar seems to be a bit of a jerk, and he is, his bloodline is directly responsible for a large chunk of the cast of Game of Thrones.
Prince Aerion “Brightflame” Targaryen (Finn Bennett)
Also known as Aerion the Monstrous, his father is Maekar, so you’re probably all up to speed on who he’s connected to up the tree. Downwards? He had one kid, Maegor, and frankly we don’t know a ton about him. That’s it! Easy!
Prince Valarr Targaryen (Oscar Morgan)
Valarr shows up towards the end of this week’s episode as a favorite in the tourney at Ashford… And that’s pretty much it! As mentioned above, both his sons were stillborn.
Prince Aegon Targaryen, aka Egg (Dexter Sol Ansell)
Surprise! Little bald Egg is in fact a Targaryen, and the youngest of Maekar’s sons at that. As mentioned earlier he’s intricately tied to the Targaryen family tree, but on the series the important bit is that he is the brother of Aerion, and his father is Maekar. It’s also noted that he left Summerhall for Ashford with his brother Daeron, but they both never arrived.
Prince Daeron Targaryen (Harry Ashton)
For some weird reason, HBO asked us to keep the identity of Harry Ashton’s character secret until Episode 4. Well, guess what? That drunk guy at the inn spouting prophecy and paying with Targaryen gold in the series premiere was — you’re not going to believe this — a Targaryen. And in fact, as explained further in this week’s episode, he’s Prince Daeron Targaryen, the brother of Aerion and Aegon. While he seems pretty keen to end the Targaryen bloodline with him (or in a puddle of wine), he does go on to marry a woman named Kiera of Tyrosh and has one daughter, Vaella. Like his brothers, he’s the son of Maekar, and otherwise not connected down the chain to anyone particularly significant from GoT.
