What is the significance of the names adopted by Celia and Rosalind?(Ganymede , Aliena)

Rosalind takes the name Ganymede, who in Greek Mythology was the most beautiful of boys (Trojan), and is carried away by Zeus to be a cupbearer. Rosalind, pretending to be a boy made the perfect choice.

Cecelia on the other hand takes the name of Aliena (the estranged one), which would allude to the girl's banishment.
