He is the father of Jaran Dragen, Garth Dragen and Ethan Snow, and grandfather of Lucius, Erik, Domeric, Mira and Merei.

Harkon and Eddard Stark during the Greyjoy Rebellion at a Tymber encampment.
Harkon suddenly died from unknown causes. The maester announced that Harkon died from an old age. However, his son, Garth, later revealed that he had poisoned his father with the Tears of Lys, a deadly and costly poison that can simulate fever and almost never leaves a trace of a murder. Garth's motives of killing his father were unknown, as he was killed himself before he could explain anything properly.
