Germans to America is a series of books which index passenger arrival records of people from German lands from 1850 to 1897. Each volume contains a chronological listing of the passenger lists, followed by an alphabetical index of each passenger in that volume. There are approximately 70,000 names in each volume. The following information is generally given for each passenger: name, age and sex; and when given: occupation, country or province of origin, village of residence (many say "unknown"), and destination (many say "unknown" or simply "US"). Also listed is the name of the ship, date of arrival, and ports of departure and arrival.

• [Note: In searching the many volumes of Germans to America, we found only one listing for someone by the name of Roggermann (with two n's). At this point (2007) we do not know if these are related to Ralph Raymond Roggerman but, since it seems to be such a rare name, it has been included.
