I have replied to that question to you directly as I don't want to put their email here.
I doubt that anyone will get much centrally on Presbyterian records, my feeling is that most Dublin ones are still with the successor churches.
Let me also add something that I was given by a keeper of Presbyterian records:-
However, I had been doing this for quite a while before it dawned on me to explain to enquirers that when a church moved premises, even though the congregation remained the same, they changed their name i.e. a Presbyterian church is normally known by their location.Therefore, briefly:
1) Bull Alley became Ushers Quay and them became Ormond Quay
Presbyterian Church.
2) Scots Church originally belonged to the Presbyterian Church in Scotland but joined the Presbyterian Church in Ireland in 1929.
3) D'Olier Street, became Gloucester Street and then Clontarf Presbyterian Church.
Ormond Quay Church & Scots Church merged in 1938 to become Ormond Quay & Scots Presbyterian Church, located in Abbey Street.
In the 1970s OQ&S became a joint charge with Clontarf i.e. two separate churches but one minister.Then in 2003 OQ&S closed and the congregation joined Clontarf. We then changed our name to Clontarf and Scots Presbyterian Church.
Scots Church was located in Abbey Street as was Abbey Street
Presbyterian Church which was destroyed - along with all their records - in 1916. The Presbyterian Church on Mountjoy Square, often called Findlater's church because of the association with that family is called Abbey Presbyterian Church. Why I don't know!!
Note the 2 Presbyterian churches in Abbey St. You need to be sure of the one you are researching. It is the Scots Church that still exists, although not functioning as a church.
