If an exact match is not
found, the name is unique and another form is displayed that allows you
to enter additional information and save the new name.
If an exact match is
found, a message box will be displayed explaining that the new name is
not unique (duplicate) and recommend that you use the "Find any
names on the ..." feature to locate all the exact matches.
You can then review these matches to determine if the name you are
trying to add actually already exists. If you review the match(es)
and determine that this is in fact a valid name shared by more than one
person or organization, you will have to use the "Duplicate this
name" feature to intentionally duplicate it with enough additional
information to distinguish it from the other duplicate(s).
