I am searching for any information on my CASEY gggggggrandfather, Abner Casey b circa 1700 County Tyrone, Ireland married Hettie (Harriet?) Green b. 1700/10 possibly in Wales. Abner and his brother Peter came to America around 1725. The had a sister name Elizabeth who I believe was born in Ireland also. I have come to a stop in Ireland. Any information on my family would be greatly appreciated.
