Looking for Birth Place of Thomas Hooley Somewhere IN Ireland

I have been researching the HOOLEY name for many years but I am stuck on trying to find the birth place of my g/grandfather, THOMAS HOOLEY, b.1835 ? Ireland.

He married MARY ANN FITZGERALD,also b. Ireland 1835 and married 1856 Swansea Wales. I have all their history up to date but cannot find any history before 1837. If anyone iS connected to this family, I would appreciate hearing from you and would be happy to pass on any infomation I have.

Regards,

Mary
