yes! it could surely be used as a real name! I love using names from books like
Caspian (the Chronicles of Narnia),
Aragorn (the Lord of the Rings), and
Jonas (from the Giver). For girls I really like
Eowyn,
Arwen and
Galadriel all from the Lord of the Rings. I would definatly use this as a fn but, if you still feel uncomfortable with it, think about using it as a mn!
