How do I display a member with a different surname to their family name?

If you have a user who has a different surname to other members of the family you can set it so they are displayed both under their family name and their maiden name. You can accomplish this as follows:

Enter the Web Office.
Open up the user's contact details.
Select the family name from the top of the user record window , the family contact details should be displayed.
Within the family details page there are 'address book printing & ordering options'.
Set 'surname to use' to 'own surname', for the user(s) you wish to display under both their own surname and their family name in the address book.
