About Maryland, U.S., Crew Lists of Vessels and Airplanes, 1910-1954

This collection contains images of passenger and crew lists of ships arriving in Baltimore, Maryland from 1910-1954. Images can be viewed by National Archives roll description and roll number.

An index has not been created for this database, but images will contain name, age, gender, ethnicity, nationality or last country of permanent residence, destination, arrival date, port of arrival, port of departure, and ship name.

It is important to note that the port of departure listed on ship passenger lists is not always the original port of departure for these individuals. A ship could make several voyages throughout the year, making several stops along the way. Oft times the port of departure found on these lists is the most recent port the ship was located at prior to arriving at the port of Baltimore. Therefore, if your ancestors emigrated to the U.S. from Germany, they could be found on a passenger list coming from Liverpool, England (if, in this case, the ship left from Bremen, Germany then continued on to Liverpool, England before arriving in Baltimore).
