For Cork city PLU or workhouse records try the Cork Archives Institute or the cork city library. http://www.corkcity.ie/facilities_archive.html http://nationalarchives.ie/sglrpb.html http://www.sci.net.au/userpages/mgrogan/cork/orphanage.htm I'd start by emailing the Cork City Library, there is a link on the first website above.
