You should have gotten a registration email with your login info at every email address that you used to register a site. You can login to gotmls.net with those accounts and then transfer your registrations to your main email account 
If you are not sure what email you used it was probably your default admin email for that WordPress site.
If you don’t know what email it was or you cannot receive email at that address then you can email me directly with your registration details and I can help you reassign those domains to the account that you want them to be under.
