This present volume concerns the Customs Passenger Lists for the Port of Baltimore from 1820-1834. In this one book the researcher has access to the records of some 50, 000 immigrants who disembarked at Baltimore during the years in question. Probably three-quarters of the arriving passengers were German and most of the remainder British or Irish. Information provided on the passengers includes age, sex, occupation, name of the country to which they belong, name of the country which they intend to inhabit, name of ship, port of embarkation, and date of arrival. In the case of German passengers, even more precise information is given--places of birth and residence and specific places of destination, for instance. Anyone interested in early 19th-century immigration records could do no better than to begin his research with this groundbreaking volume.
