Account recovery question.

Before the Battle.net integration I had three accounts. The first account is the one I integrated to my battle.net account. A second one I used for multiboxing I let expire and transferred the characters to my main account (this one). This happened pre-battle.net integration as well.

The third one is tricky. I opened it for my younger brother (under age at the time) with my parents permission. He has since gone off to college and stopped playing. I would try to recover the account but both my brother and I can't remember the pre-battle.net account name, the email address I had the account registered under was my brother's email address at the time (he has since switched emails three or four times...). So, as far as I know, I have a dormant WoW account that I can't access.

Is there any way for a blizzard representative to find and recover this account using my first and last name?
