You shouldn't have 2 Google accounts on it anyway. A Google account is for backup. and backing up to 2 accounts leads to problems - like backing up to one account, making changes (like adding and deleting contacts for a few months), then restoring from the other account - and losing all your changes.
If you have more than 1 email account, they all go into Accounts/Email, Accounts/Gmail, Accounts/<whatever email app you use> or into Settings in the email app itself. The addresses of the email and Google accounts may be the same, but they're not the same accounts.
