I am researching my mother's family. Have traced back to Michael O'Rourke, b. about 1800, married Mary Campbell on April 22, 1834 in Killygonlan, County Tyrone. Michael and Mary emigrated to Oneida County, New York. He died August 2, 1888 in Camden, NY. The family was from the Townland of Elagh, not too far from Cookstown, on the west side of Lough Neagh. There are not a great number of O'Rourkes in County Tyrone. Is it possible there might be a connection?
