Thanks Heywood for your quick reply and help with where to order the certificate. Yes that is the marriage I have. Problem is when you fill in the marriage application form they want the church name and address and we dont know which one it is. It has to be a Catholic church and I think as they lived in Stephen St maybe it was in that general area -South Dublin? Also found a Patrick Walsh baptised at St Audeon, Dublin in May 1877 and this Patrick may be the one we are looking for. His parents were a Patrick Walsh and Eliza Tyrrell. When you said order the photocopy for 4 euros do you mean it is sent to an email address for 4 euros instead of costing 20 euros.?
Many thanks.
