Nathan, Do you know who your great grandfather's father was? My GGrandfather was Patrick Cusick. He was born in 1832 in Ireland. He had at least one brother - Phelim (Phillip) - born in 1830. Patrick married Ellen Gaughen and had at least three children born in Ireland ( around the 1860s) - Thomas, Bridget and Mary. Then they emigrated to Pennsylvania in 1873.
