I remember looking for folks coming into New York, and there being a 3rd entry port called the BARGE Office, can you elaborate, Did this one port exists before Castle Garden and or Ellis Island?
Olive Tree Answer:
From 15 June 1897 to 16 Dec. 1900 the processing station was the Barge Office. Go here for more information on Ellis Island
There is also a nice little chart showing a detailed timeline for Immigrant Processing Stations at the Port of New York from 1624 to 1924 found at Ships Passenger Lists to New York
