Targaryen Family Tree
Your Ultimate Guide to the Long and Twisted Targaryen Family Tree

Joffrey Velaryon is the youngest of Rhaenyra and Laenor's sons. His birth is shown in episode six of "House of the Dragon." Like his brother's his true father is Ser Harwin Strong, who is killed by his own brother, Larys, shortly after Joffrey's birth. Joffrey is named for his father's lover Joffrey, who was killed by Ser Criston Cole during Rhaenyra and Laenor's wedding feast. In "Fire & Blood," Lord Corlys kept Laenor from naming Jace and Luke after Joffrey, but Laenor finally seized the opportunity with their third child.
Also like his brothers, Joffrey bonded with a hatchling dragon Tyraxes. When the Dance of Dragon begins, the dragon is not quite big enough to fight yet, and Rhaenyra forbids Joffrey from fighting.
