I search the IFHF's online database @ ROOTSIRELAND.IE. It has abt 19 million B/M/D and other records for MOST Irish counties. Records before 1863 are increasingly sparse and almost non-existant prior to 1800. Many early B/M/D events weren't recorded, or the records didn't survive.
For John Guilfoyle B ???? Co. Kildare, with a father forenamed John and mother Ce(cilia), I found 0 records.
Suggest you visit this website, register (free), duplicate my search (also free) and opt to be notified as more records are added to the Kildare database (a slim chance).
