Deriving from the New York newspaper The Shamrock or Hibernian Chronicle, Passengers from Ireland includes all data published on immigrants during the entire seven-year run of the paper and presents the lists in their original format so that family groupings are readily apparent. In substance, it comprises passenger lists for the whole period 1811 to August 1817, supplying information on over 7,000 travelers, such as name of the passenger (sometimes listed with his parish or county of former residence), name of the vessel, name of the ship's captain, length of journey, port of departure, port and date of arrival, and additional remarks concerning such untoward experiences on the high seas as seizure and impressment.
