Thomas Walsh and Mary Geraghty

My 2x g grandparents are Thomas Walsh (1824?)and Mary Geraghty(b 18??). They were married in Crossboyne church November 4, 1852. We have that record. What my family cannot find is each of their parents and the year they were born. The family moved to Hollymount and had 12 or 13 children. Thomas died in Kilrush in 1919 and mary died in Purrauns, Hollymount. Any info greatly appreciated.
