I am hoping that someone on the list has access to a book that I remember seeing once. It is a listing of Irish immigrants on a particular shipping line that arrived in New York. I remember seeing it at the Irish American Historical Society in NYC. I also know that there is a large volume set of Irish immigrants listings, but I have only seen one volume of that. I have just learned the range of years that my ancestors came over. It was between Nov. 1, 1962 and July 4, 1866 with the most likely year being 1864. Does anyone have access to these books or volumes and can look for John and Margaret O'Hara with their son John (b. 1860) and a possible other son, Thomas, who may have been born at sea? Thanks for any help. Mary Theresa McCombe
