When adding a second Gmail account to my iPad recently, I needed to differentiate the two accounts clearly. I decided on “Gmail – ” followed by the beginning of the account name.

When adding a new account, the Account Name (shown as your name in outgoing mail) is set to the Account Description value by default. To change the Name, go to Settings -> Mail, Contacts, Calendars. Then under Accounts select the desired account, then click the Account line on the next screen as well. Here you can change Name and Description independently:
