If the NACO FAQ is still current, then the guidelines for what to do when you encounter and need to
edit an undifferentiated name are in the DCM Z1, section 008/32.
The essential bit is here:
“When information is found to distinguish a person in an existing undifferentiated name record:
• Always create a new name authority record for that person, with distinguishing information, and add an indication that the person was formerly on an undifferentiated record (see
667 notes on records for identities previously on undifferentiated records below).
• Transfer the citation 670 pertaining to that person from the undifferentiated name record to the new name authority record and edit as necessary.
• If the undifferentiated NAR is not being deleted because multiple identities remain, delete the pair of 670 fields pertaining to the newly created NAR.
• If more than one identity remains in the undifferentiated NAR, and there is not sufficient information in the NAR to create new NARs for each name, leave the NAR coded AACR2.

Subject: [PCCLIST] How to split one NAR into two?
I need to control an author heading for for John Callanan, a priest. But it will not control because the NAR for John Callanan (ARN 3561329) contains info for both the priest and
some photographer, and has the prohibitive 667 field. How do I split these into two NARs? Like this?
(1) Strip the priest info from the NAR and Replace Record, then
(2) Make a new NAR for the priest, with a distinguishing identifier?
Or, since the priest also has a name/title record, leave the non-differentiated record for the priest, and create a new record for the photographer?
