We are leaving on April 20th and will be in the Glengarriff area (staying in Baltimore for 2 nights) at the end of the month. The Sacred Heart site does mention an old grave yard.
" The Church of the Sacred Heart, Glengarriff, is the local Roman Catholic church and was erected in 1902. It replaced the “Old Chapel” in the burial grounds at Cappyaughna which had been built in 1829. The “Old Chapel” has been renovated and is now the Parish Hall."
Parish Priest : Fr Pádraig Kennelly P.P.
"The Old Church is now the Community Hall. The Old Grave yard surrounds the Hall."
I'll get pics and info on everything Sullivan and O'Shea that I find.
