Aerys Targaryen (son of Aegon)
|Title||Lord of Dragonstone|
|Book(s)||The World of Ice and Fire|
Lord Aerys Targaryen was a member of House Targaryen and Lord of Dragonstone before the War of Conquest. He was the son of Lord Aegon Targaryen and his sister-wife Elaena Targaryen. He was the father of Aelix, Baelon and Daemion Targaryen.
Aerys's grandson Aerion Targaryen later married Valaena Velaryon, who was said to have a Targaryen mother. This may imply that Valaena's mother was a daughter of Aerys - unless it was a minor Targaryen cousin, or there was an age disparity in the match.
