Matt, it is a bit confusing:
The accounts created for the owner during install are quasi-Admin accounts which still don't have all of the permissions of the master hidden Administrator that some of us run under (at our own risk).
I only create standard accounts for non-owner Users who need to be restricted in using someone else's computer, even perhaps within a family.
I believe you deleted the account correctly in User Accounts and that leftovers are common. Many times when I delete an account I find the User file there and simply delete it after checking for contents.
