Hi Mary/Debbie,
I visited Killilagh Graveyard in Doolin (near Lisdoonvarna) Last Friday 27th April. There were several Sammon and Fitzgerald headstones. These go back to the 1800s. Doolin is a a satellite parish of Lisdoonvarna. Sadly, the Doolin Parish records only date from 1969 for "births" and 1928 for "Deaths". As you may know, civil records date from 1864. On a quick search, I have not found a website with Killilagh gravestone inscriptions. Anyway, I hope this gives you a tread to follow up at some stage.
