Hi Andrew - Not sure how much detail you already have but when I was researching my tree I found a record of a Daniel Ahern (no relation to my line)- His parents were Michael Ahern and Bridget Hurley; he was born on the 8 Sept 1878; the family address was given as Ballynagally in the Parish/District of Kilteely & Dromkeen. Although I don't have records for these to prove parents - It's likely these are also children of Michael & Bridget: Laurence b1870, Mary b1872, Honora b1874, Michael b1876. No record of a 'John'. If you want to email me - my email is gerard "at" aherne.com.au - I can send you the baptism extract. Hope this was of some help. Regards Gerard.
