I searched the IFHR's online database at ROOTSIRELAND.IE. It contains abt 19 million B/M/D records, but DOES NOT cover all Irish counties yet.
For A(ndrew) McKelvey B 1814 +/- 5 yrs, anywhere in Ireland, I found 0 records.
1814 is VERY early for Irish records. Not all B/M/D events were recorded, and fewer have survived. Suggest you visit the database, register (free), and wait for more records to be added. The IFHF will notify you as records are added. However, at this early date your chances of finding records are likely less than 10%.
