Baby Boy Names?!

Lauri

We just found out the gender a couple days ago and I am so excited to be having another baby boy-- the only problem is, I only had girl names picked out. My son, who will be just under 2 when this one is born, is named Dresden Grey after Harry Dresden from the Dresden Files book series and Gandalf the Grey. We would like to stick with the magical literary theme but haven't made any decisions yet. Some of our potentials are:

Owen

Remus

Kaliden

Cassius

Calisto

Orion

Ephraim
