I had very good luck with Sean O'Neil who lives in Dublin and researches in surrounding areas of County Cork. He charges $100 US dollar or equivalent ( 111 EURO ) payable in advance by personal cheque or cash in post ( but no $100 bills) or bankdraft made out in 111 EURO payable at Bank of Ireland, Dublin. He was very responsive to my inquiry and I would recommend him highly. maghoneill@eircom.net (SeanO'Neill)
