Welcome to Android Central! The primary Gmail account will be the one associated with the Google account that the phone is registered to. It sounds like this was originally your aunt's phone. You'd need to remove all Google accounts from the phone, and then set it up again with your own Google account. Go to Settings>Accounts>Google, select each account, tap Menu, then Remove Account. After you've removed all of the Google accounts, tap Add Account and proceed with adding your own Google account.
