I am searching for information on William Rigney's ancestors. I know that his parents are John Rigney (Abt 1835) and Catherine Garrity (Geraghty) (Abt 1848)of Dublin. They later moved to Liverpool. William and his brother John (Jack) left on ships after 1881. William settled in New Orleans and married Catherine Gunning, Jack got into a fight with a cook on a ship and was thrown overboard.
