When the new church at Powerscourt gates was built, Mervyn, 7th Viscount, “requested Mr William Buckley, the then innkeeper of the Powerscourt Arms Hotel Enniskerry, who was then churchwarden, to furnish me with a list of the parishioners…[so that] the burials in the old churchyard are restricted to those families who had rights prior to 1869.” – where the old churchyard was that beside the house.
As luck would have it, this list still exists in the Powerscourt Papers at the National Library of Ireland, and I have reproduced it below. Some of the names have been annotated in pencil “decd” – so the list was obviously updated at some stage. It is in two parts: those living in the Parish and those outside. A note on the front page said that a copy of the list has been given to (I think) H Galbraith in 1879.
