Below is the response I received from the Registrar's Office. I have sent the funds in but I have not received the results yet. When I was in Ireland I ordered some copies when I was in the Registrar's Office because I had so many. The were here when I returned. Dear------ You should apply  by post to this office including as many  details of the event in question as you can, i.e., full names, date and place of event, name and occupation of fathers and mothers maiden names. Obviously the more information you can give us the more chance we have of finding the records you are looking for. The fee is IR£5.50 for a full Certificate (IR£3.00 for a photocopy of the microfilm record which is only of use for research purposes). Our index is date based and is in a manual format so we need accurate dates (correct year at least), we will then check the given year and the year either side of it). We cannot accept credit cards, but we will take International Money Orders(in Irish Punts), U.S. Dollar cash or cheques (minimum cheque amount $10.00) Sterling cash, cheques or Postal Orders, (your bank should be able to tell you the current exchange rates). Cash should be sent by registered post and cheques etc should be payable to General Register Office. Our postal address is General Register Office, Joyce House, 8/11 Lombard St, Dublin 2. Please note that due to a severe staff shortage there is a 10-12 week backlog of applications. If a Cert is needed urgently you should explain the situation in your letter and we will do our best to expedite its issue. If you only have imprecise or uncertain information there are private commercial companies who do this kind of work contact: the Association of Professional Genealogists in Ireland at 2 Kildare Street, Dublin 2. OR  if you ever come to Dublin ( which is a fine city and well worth a visit) we have a research where the public can access our records. Tom Joyce G.R.O.
