Searching for info on Martin Cunningham & Catherine Whitty

Their daughter was born in Scotland and her birth certificate states that Martin and Catherine were married in New Ross sept 11 1861

martin's death cert. has his parents listed as James Cunningham and Bridget allyman.

Catherine's death cert. does not have her parents names just _____ Whitty

Any help tracking them down would be greatly appreciated.

thanks
