Kelly family

Hi I am trying to find Michael Kelly and his wife CAtherine O'Neill. I know all the children were born in a place called Clonfean wich is now changed to Cloonfean or Cloonkeen.I have baptisms for all the children they were all baptised at Dunmore rc church.The thing is I can't find a marriage for Michael and Catherine or even where they were born. If any one can help I will be so grateful. The children are as follows Sarah b 1835, Bridget b 1836,Patrick b 1837,John b 1838-1839, John b 1840, Michael b 1843 and Mary b1845. I think Catherines father was called Patrick O'Neill. Thank you and kind regards.
