Know In-Game Login, but not EQEmulator Login

[Sinbil]

I'm sure I'll belong in the Idiot Post section, I had tried searching for the issue I'm experiencing, but I may be the first moron in my situation. I have apparently made up 4+ accounts over the years. I have characters on 2 of the accounts and play them regularly.

I'd like to update my passwords as I've had some online security issues. Using my various emails, I was able to update my EQEmulator details for 3 accounts, but only 1 of the 2 accounts I have characters on, the other 2 accounts have no characters.

I checked that my missing account is not tied to any of the other 3 logins. I've exhausted all of the email addresses I remember having and can not find the missing account. I have the ingame login details, but have no way to change my password. Is it possible to identify the email address that an account is tied to if I provide the in-game username? I realize this probably sounds sketchy and will probably be a fruitless effort, but I'm out of other options.

Thank you for the time.
