Looking for any details for Arthur & Hanora O'Leary

Hi am keen to get more details on Arthur b:1770 & Hanora (nee Harigan), 1775 O'Leary'. They left Ireland with their son Jeremiah b: 1798 & his wife Bridgit & four children to Australia from Mallow, Cork on the Calcutta, on assisted passage.

They arrived in Australia on 16th Oct 1838

I would love to find out where in Ireland (Cork) Arthur & Hanora lived, worked (farming) & when & where they were married. The above details is all I have of them.If possible any information of both parents would be great too, but I know that's a big ask!

Thank you for your great work on IRO!

Regards
