Unsure of Gmail account linked to account

Just came back after a break and am having to change all of the passwords for my accounts. The problems is that I can't figure out which gmail goes with one of my accounts. (used to be my brothers). He can't find an email and neither can I. Neither of us really use our gmails other than for this.

It could just be that the email hasn't been sent, but we have no way of knowing. If a GM could DM me or point me to the right place to get help that would be great. Don't really want to post the account name here.

Names on the account (Icecrown/blackrock)
-Avvo
-Tezoi
-Tezz
-Kittenlol
-Laintime

One of the items bought with vote points was an arp trinket on the rogue.

Thanks.
