Donoghue Family Kilcummin Killarney

I am trying to find any family connections with Patrick Donoghue who Married Mary Crowly in Kilcummin on 1855. They had four children all born in Killarney . John 1856 , Mary 1859 , Cath 1867 and Pat 1868 .

Any help would be appreciated .

Regards

Tony Donoghue
