Thank you, Erin!
I have taken another look at Barry-1308. This is going to be a tough one, but if we can get ahold of the Griffith's Valutation and subsequent Cancellation Books, that would help. Further back, we need the Tithe Applotment Books from the 1820s and 1830s. We aldo need to find what church he attended as there might be baptismal records, even though these were not legal for Catholics before 1829, some do exist. St. Patricks in Skibbereen goes back to the early 1800s with their records, if they will let you have them.
