Thomas Warren b 1829 which Co Cork parish

Hi All

I am trying to discover where my Gggrandfather was born in order to try and trace his parents.

The info I have is Thomas Warren born in 1829 to John Warren and Catherine MacIntyre also spelt McIntyre.

His place of birth is given only as Co Cork Ireland.

I do not know their religious denominations, but family story indicates that it could have a cross denomination marriage which caused much bitterness.

No other know siblings.

Any help will be greatly appreciated.

Cheers Will
