Daniel O'Grady born C 1830, Castle Durrow, Laois

Hi, I am seeking any information on Daniel O'Grady and his family. Daniel was born C1830 to Martin O'Grady and Margaret (Phelan). Martin was an architect and Daniel's place of birth is listed on his death certificate as being Castle Durrow, Laois. He married Ann Hyland of Co Down on 1 May 1854 at Lisnagade, Co Down and on the 21st October, 1854 they left Ireland for Australia. Any help would be appreciated. Regards, Norma Mason Bakker
