Edit an adult account. You will find the last name and the first/middle fields for the non-member guarantor in the form.
Bug 14570 renamed "surname" and "firstname" from the "Contact" block with "Guarantor surname" and "Guarantor firstname". I am wondering if this was intentional. I don't think it makes sense to remove surname and firstname if we keep the other fields from "Contact".

The non-member guarantor information should not be with the "Contact" info. The contact info (phone numbers and e-mails) have to do with the patron. The non-member guarantor info needs to be with the rest of the guarantor fields.
