“Prince Aenys was the first to marry. In 22 AC, he wed the Lady Alyssa, the maiden daughter of the Lord of the Tides, Aethan Velaryon, King Aegon’s lord admiral and master of ships. She was fifteen, the same age as the prince, and shared his silvery hair and purple eyes as well, for the Velaryons were an ancient family descended from Valyrian stock. King Aegon’s own mother had been a Velaryon, so the marriage was reckoned one of cousin to cousin. fruitful. The following year, Alyssa gave birth to a daughter. Prince Aenys named her Rhaena, in honor of his mother. Like her father, the girl was small at birth, but unlike him she proved to be a happy, healthy child, with lively lilac eyes and hair that shone like beaten silver.”
