The missing generation is not between Daemon 1 and Aethan but between Daemon 2 and Corlys. Corlys inherited Driftmark from his grandfather.

So it goes like:
 * Velaryon
 * Valaena, born around 45BC
 * Daemon 2, born around 45 BC
 * Corlys 1, born around 19 BC
 * Aethan, born around 20 BC
 * Alyssa, born in 5 BC
 * Daemon 2 born around 5 BC
 * Velaryon, born around 30 AC
 * Corlys 2, born in 53 AC
