When it comes to House Targaryen, family relationships are always a bit messy.

The dynasty at the centre of HBO drama House of the Dragon is filled with multiple marriages, recurring names and, erm, incest - which can make it tricky to keep up with who is related to who.

One minute someone is your auntie, the next she’s your step-mum. That’s how things roll in Westeros.

To help you guide you through the knotty Targaryen family tree, keep reading for our step-by-step walkthrough the different generations in House of the Dragon.

First Generation

King Jaehaerys I  (Played by Michael Carter)

House of the Dragon kicked off with a prelude about ‘The Old King’, King Jaehaerys I, who enjoyed the most peaceful reign in Targaryen history.

When he approached his death, he had no heir apparent, so the Great Council voted and the decision came down to Jaehaerys' grandchildren Rhaenys and Viserys.

Despite Rhaenys having a stronger claim – her father was Jaehaerys’ oldest son Aemon – she was overlooked because she was a woman. Hence her nickname, The Queen Who Never Was.

Grandchildren:

King Viserys I

Rhaenys, The Queen Who Never Was

Second Generation

King Viserys I (Played by Paddy Considine)

The first king we spend time with in House of the Dragon, King Viserys rules at the height of Targaryen power with dragons thriving in the realm.

He marries Aemma Arryn (his cousin) and they have one daughter, Rhaenyra.  Viserys and Aemma continue trying for a boy who can become his heir, but Aemma dies during childbirth and their son and heir dies within 24 hours of being born.

After Aemma’s death, Viserys marries Alicent Hightower – the daughter of Hand of the King, Otto Hightower. Alicent is also the best friend of his daughter Rhaenyra.

Viserys and Alicent have three children, Aegon II, Helaena and Aemond.

Despite now having a male heir, Viserys sticks by his decisions to declare Rhaenyra as his successor. Whether everyone in the realm agrees with his decisions is another matter…

The younger brother of King Viserys and a presumed and possible heir to the king at the start of House of the Dragon. More arrogant and erratic than his older brother, Daemon is looked over by Viserys, who names his daughter Rhaenyra his heir instead.

Daemon has an unhappy first marriage to Rhea Royce of the Vale. Rhea dies falling off her horce, and it is implied Daemon was responsible for her death.

After having a request to marry Rhaenyra (his niece) denied by Viserys, Daemon has a second marriage to Laena Velaryon – the daughter of Rhaenys and Corlys Velaryon.

Daemon and Laena have two daughters, Baela and Rhaena – but Laena dies during childbirth along with their third child.

After Laena’s funeral, Daemon marries for a third to time to his niece Rhaenyra. Rhaenyra requests the marriage to shore up her claim to the throne as fears grow Alicent Hightower and her sons will dispute her authority.

Viserys sticks by the succession plans with Rhaenyra, even after he has two sons from his second marriage to Alicent Hightower.

Rhaenyra’s first marriage is to Laenor Velaryon, the eldest son of Rhaenys and Corlys Velaryon.

On paper the couple have three sons, Jacaerys, Lucerys and Joffrey. However, everyone in the kingdom appears to be well aware that the boys’ real father is Harwin Strong.

The constant rumours about the boys’ parentage forces Rhaenyra and Laenor to take drastic action and with the help of Prince Daemon, fake Laenor’s death.

Laenor is able to start a new life on the other side of the Narrow Sea and Rhaenyra is free to marry for the second time to Prince Daemon.
