When using Address Book in Mac OS X v10.4 through v10.5.8 to print mailing labels or envelopes, the names that print above the address will include the prefix, suffix, first, middle, and last names on the card you have selected, along with any related names on the card that are labeled as spouse, partner, child, father, mother, parent, brother, or sister. These related names will appear on the label or envelope if no card exists for the related name, or if another card exists for the related name which contains the same address as the card you are printing
