regarding the google rankings i don't see how you can divorce the cork city hits from the cork county hits which is a very relevant distinction on whatlinkshere there are inlinks to city and to county pretty close if there were no other convention then cork would already be a disambiguation page even without cork material to contend with however the overriding convention appears to be wikipedia talk manual of style ireland related articles disambiguation of locations in ireland where a town and county have the same name the county article should be named as county countyname and the town should be located at county townname if no further disambiguation is needed for example sligo and county sligo it's only a talk page suggestion but absent anything stronger it's unexceptionable however throw cork material back into the mix and it's clear that it's not a contest between material and city it's a contest between material city and county to me is a clear case where disambiguation is required as the only reason city is preferred to county is a very obscure and largely arbiitratry wikipedia convention
