Check your credit reports. Pulling your credit report and credit score is the most accurate and convenient way to find all of the accounts that have been reported in your name. Your credit report will display every open account in your name, from bank accounts to credit cards and more.

Go to http://accounts.google.com/signin/usernamerecovery and enter any email accounts or phone numbers that you've had for a while and which may have been used as recovery info. The “find your email” page can help you locate any forgotten Google accounts. On the next page, you'll be asked for your name.

In order to create a Google Account without signing up for Gmail service, visit https://accounts.google.com/signup and pick "I prefer to use my current email address" option. After filling the form and confirming email, you can then add that newly created Google Account to each of your Search Console services.
