Aynnie,

Google advises us, in plain language.

At Google, we take your privacy and security very seriously. Therefore, we're committed to returning accounts only when we're sure we're giving them back to the accounts' owners. Because Google doesn't ask for much personal information when you sign up for an account, we don't have many ways to verify that you own an account.

in other words, if you can't use either the account name / password, or the email address, to recover access to the Blogger account, then you may be out of luck.  Blogger has no legal right to give "you" access, if you cannot prove ownership.  Deletion is not an alternative, either.

If you have not found the login instructions in any of your email accounts then either:

• You have not checked all of your accounts.
• You are not the owner of the blog with that blog name.

If this is a problem because you cannot remember which GMail account you used, then you probably have too many GMail accounts.

There's no simple solution here.  You might be able to use the (recently improved) Google account recovery tool, if you remember what the email address was, and enough auxiliary details.  We hope that you can see the bigger picture, and read the FAQ, objectively.
