Baby Boy needs a name.

We have a 7 1/2 year old daughter named Ailani. We have a two year old son named Damien Giovanni. We call him Giovanni because we were so indecisive and he was not named until minutes before we left the hospital. My husband picked Damien (I still don't particularly like it) and I chose Giovanni. Now we are expecting another little boy in October. What the heck are we going to name him?! Ailani and Giovanni go well together and we are looking for a name with the same ending sound. Any suggestions would be fantastic!
