A Knight of the Seven Kingdoms Targaryen family tree: How everyone connects

Another Game of Thrones show means another Targaryen family tree to memorize, and HBO's A Knight of the Seven Kingdoms is no exception.

The prequel series primarily centers on lowborn knight Ser Duncan "Dunk" the Tall (Peter Claffey) and his young squire Egg (Dexter Sol Ansell), following their time at a tournament at Ashford Meadow. However, despite A Knight of the Seven Kingdoms' focus on Westeros' smallfolk, it's not long before the Targaryens show up to bring drama (and tons of "ae" names) to the tourney.

If you're wondering how all these new members of the House of the Dragon are related to one another, you've come to the right place. Below, we've laid out the Targaryen family tree as it stands heading into A Knight of the Seven Kingdoms Season 1. For simplicity's sake, we've pruned some of the branches to show how these family members tie back to House of the Dragon and Game of Thrones, and we've focused on the major Targaryen players you'll meet early on. Read on to meet your newest crop of Targaryens — and see how they all connect.

King Daeron II Targaryen

The current head honcho of Westeros is King Daeron II Targaryen, the great-grandson of House of the Dragon's Rhaenyra and Daemon Targaryen. You won't actually meet him in A Knight of the Seven Kingdoms, but his reign has molded the Westeros you'll see in the series.

By this point, almost 80 years after the events of House of the Dragon, Westeros is experiencing a period of peace, and it's all thanks to King Daeron II. He put an end to the Blackfyre Rebellion, a bloody coup attempt by legitimized Targaryen bastards, and he also managed to bring Dorne peacefully into the Seven Kingdoms. They don't call him "Daeron the Good" for nothing!

Daeron II's sons: Baelor and Maekar Targaryen

King Daeron II has four sons with his wife, Dornish Princess Myriah Martell: Baelor, Aerys, Rhaegal, and Maekar. For the purposes of this show, you really only need to care about the first and fourth sons, Baelor and Maekar.

Prince Baelor "Breakspear" Targaryen (Bertie Carvel) is the eldest of Daeron II's sons. Not only is he heir to the Iron Throne, he's also Hand of the King. Like his father, he's deeply respected and viewed as wise and just. He has two sons with his wife Jena Dondarrion: Prince Valarr (Oscar Morgan) and Prince Matarys, but only Valarr appears in A Knight of the Seven Kingdoms. Notably, Baelor doesn't have the Targaryens' silver hair, but instead favors his Dornish side with darker hair.

Harsher than his brother (but with much more silver hair), Maekar (Sam Spruell) is the Prince of Summerhall. He also has six children compared to Baelor's two, and several of them will play a larger role in A Knight of the Seven Kingdoms.

Maekar's children: Daeron, Aerion, Aemon, Daella, Aegon, and Rhae

Maekar and his wife Dyanna Dayne have six children together: Daeron, Aerion, Aemon, Daella, Aegon, and Rhae. A Knight of the Seven Kingdoms primarily focuses on his sons, leaving Daella and Rhae out of the story.

His first son, Daeron (Henry Ashton), is also known as Daeron the Drunken, and he has the prophetic dragon dreaming gift of select Targaryens. House of the Dragon's Helaena Targaryen is similarly gifted.

Maekar's second son, Aerion (Finn Bennett), fits the bill of the classic "mad" Targaryen. Thinking he's a dragon in human form, he dubs himself "Aerion Brightflame" and wears a fiery helmet that is, admittedly, pretty sick. Still, his fashion choices can't make up for his cruelty and sadism.

Game of Thrones fans have already met Maekar's son Aemon: He's none other than Maester Aemon from Castle Black. Don't expect to see him in Season 1 of A Knight of the Seven Kingdoms, though, as he's currently studying to be get his maester chain in Oldtown. However, his existence in the world of A Knight of the Seven Kingdoms serves as a reminder of how the show connects to Game of Thrones, whose events are a little under a century away.

A Knight of the Seven Kingdoms premieres Jan. 18 at 10 p.m. ET on HBO and HBO Max.
