A county man (6)
I believe the answer is:
tyrone
This clue is a double definition.
'a county' is the first definition.
(county of Northern Ireland)
'man' is the second definition.
(Other definitions for tyrone that I've seen before include "Irish county" , "County of N. Ireland" , "Traditional county of Northern Ireland" , "Omagh its chief town" , "An Ulster county" .)
