Finding husbands family - McCarthy and Healy

Hi we are coming to cork next Friday for a few days. My husband never really knew his dad and knows nothing past him. All we know is his grandparents were born in cork. 
mew have traced them , but they had moved to the Uk and died here. 
we managed to trace his great grandparents who were Patrick McCarthy and Christina McCarthy was Healy 

patrick died on 2 May 1929 and was buried in st finbars cemetry

Christina McCarthy died 1 Feb 1955 and was also buried in at finbars cemetery 

Their address when they died was 18 model villages. 
We are trying to find out if he has any living relatives in cork. 
the search is hard with no family to give him information but would just love to know his roots etc 

thanks Nicola McCarthy
