Mccarty IN PA

Looking for info on Benjamin McCARTY, who died in Beallsville, PA on 5 APR 1861. I know he was born in 1779, probably in PA. His father's name was Paul, mother was Catherine SPHOON. I'd like to find where in Ireland they were from, and I think Paul and Catherine was the ones who came to America. My sister is going to Ireland this summer and I'd like to have specifics for her to look up while she is there. An obituary or burial record would be great.
