Family Tree Targaryen

Every Jaehaerys Targaryen, told apart

Why they kept reusing the same names

Naming a Targaryen child was a political act. Calling a son Aegon invoked the Conqueror. Calling him Jaehaerys invoked the Old King and fifty five years of peace. Calling him Daeron invoked either the boy who conquered Dorne or the man who married it into the realm, depending on which one you needed.

The cost of that habit is a family tree where the first name tells you almost nothing. The chart on this site labels every person with their dates and their epithet for exactly that reason. If you are trying to work out which one you are looking at, the year is the fastest way in.

Questions about the Jaehaeryses

How many Targaryens were named Jaehaerys?

At least 4 appear on this family tree, of whom 2 ruled from the Iron Throne. The Targaryens reused a small pool of names deliberately, to tie each new child to an ancestor worth invoking.

Why are there so many Targaryens named Jaehaerys?

Naming a child after a celebrated ancestor was a claim on that ancestor’s reputation. Aegon invoked the Conqueror, Jaehaerys invoked the Old King, Daeron invoked the Good. The result is a family tree where a first name tells you almost nothing.

How do you tell them apart?

By their dates and their epithet. Every Targaryen who mattered picked up a nickname, and where they did not, the reign years do the work. This site labels every node on the chart with both.
