These passenger lists, which cover the period of the Irish Famine and its aftermath, identify the emigrants' "actual places of residence", as well as their port of departure and nationality. Essentially business records, the lists were developed from the order books of two main passenger lines operating out of Londonderry--J.& J. Cooke (1847-67) and William McCorkell & Co. (1863-71). Both sets of records provide the emigrant's name, age, and address, and the name of the ship. The Cooke lists provide the ship's destination and year of sailing, while the McCorkell lists provide the date engaged and the scheduled sailing date. Altogether 27,495 passengers are identified.

Main entries in Passenger and Immigration Lists Index provide information including name and age of immigrant; year and place of arrival, naturalization, or other records which indicates person indexed is an immigrant; code indicating the source indexed and the page number in the source which contains the record; and the names of all listed family members together with their age and relationship to the main entry.
