I located Patrick Quinn on the U.S. Naturalization Record Indexes , 1791-1992 on Ancestry.com. He arrived in the United States in September, 1836. His port of arrival was Albany, New York. He became a naturalized citizen on August 22, 1856. Witnesses: John Bierne & James O'Reilly.
I just found this information in the last 6 months but I have not proven for sure that it is my ggg grandfather Patrick Quinn.
