Hi Joe, I am finding many of my Irish from Leap, Rosscarbery, Skibbereen and Drimoleague, Cork who bailed to Dowlais, Merthyr Tydfil Wales from 1850 through 1865. Many subsequent generations then went to Sharon (Hickory) Mercer County (and likely Pittsburg at first), and then New Castle, Lawrence, PA. I am researching that community movement at present. The New Castle Library has been very helpful. Perhaps yours did something similar? Regards, Candi in California
