I am looking for any information on James Buckley or his twin sister Hannah Buckley born in Ireland in 1815, location unknown. They are listed in the 1880 census in Chicago, IL. James was a widower with a son James H. Buckely , a Chicago policeman, who is my grandfather. James H. married Katie Carroll. I would like to know where in Ireland James and Hannah were born and when they came to the U.S. Thank You, Mary
