Two accounts, one email address

[rblevow]

My wife was trying to replace the lost password for her account when I thought to use her Apple account to access it.  I ended up creating a new account with the same email address.  The new account masks the old one and became the login for that email.  She needs to regain access to the old one to recover information there.  1.) Is the old account still there?  If so, will either of the following work to restore it to visibility.  2.) Delete the new account.  3.) Change the email address on the new account.  4.)  Backup is to icloud.  Is there a way to recover list of session ids? Anything else?  Thanks.
