I found my immigrant ancestor on both the Baltimore Passenger Lists and the Castle Garden records. Both records give identical information regarding date of arrival, birth year, age, sex, name, ship name and departure location (Bremen).
I don't understand how he can be on both lists. It seems to imply that he arrived in New York AND he arrived in Maryland. I don't know what to think of this or which location to identify as his place of arrival.
Can anyone help me understand this? Thanks.
