See how the main characters in 'House of the Dragon' are all related to each other

• Warning: Spoilers ahead for season one of "House of the Dragon."
• We made a chart showing the family tree (or we should say "shrub") of House Targaryen in HBO's show.

George R.R. Martin's "Fire and Blood" details the complicated legacy of House Targaryen in Westeros. Now HBO's "House of the Dragon" TV series brings a piece of it to life as we follow the reign of King Viserys through to the civil war that erupted after his death.

Here is a look at how all the major characters in "House of the Dragon" (so far) are related. Scroll below the graphic in order to see our breakdown of the most interesting or pivotal inter-family relationships.

So, with the context of the family tree above, here are the most pivotal relationships you should keep in mind:

• Rhaenys was King Jaehaerys' granddaughter through his oldest son, while Viserys was the King's grandson through his younger boy. That's why some believed Rhaenys' claim to the Iron Throne was more justified than her male cousin's claim. But the men of the realm thought differently.
• Alicent and Viserys married their only daughter, Helaena, to their oldest son, Aegon, in between one of the time jumps. (Now Helaena and Aegon have two children of their own, which you can read about here.)
• Now that Daemon and Rhaenyra (who are uncle and niece) are married, their combined children from their first marriages are the following order in terms of age: Baela, Jacaerys, Rhaena, Lucerys (now dead), and Joffrey.
• Note: Daemon and Rhaenyra also have two other trueborn children together that are not on this family tree yet, given their younger age: Aegon the Younger and baby Viserys, named for his grandfather.
