i used free searches again, on http://ifhf.rootsireland.ie. i came up with the following-using only surnames together-no given names, no year or location.

O'hara, Teresa Hardy, Thomas 1879 Co. Antrim


Hardy, Mary O'Hara, Jas. 1809 Co. Galway

on the https://www.findmypast.ie website-entering the name john hardy-1770 to 1800, UK, Dorsetshire-i found the following:

John Hardy
Army List 1798

Collections from Regiment
United Kingdom Thirty-Fifth (Or
Year The Dorsetshire)

i don't know if any of this helps. continued good luck with your search.
