In response to:
"The mention of a different list for embarking >from Hamburg and for entry
into the U.S. is a new one on me. I am under the
impression that the passenger manifest was created at the port of embarkation
and were the *same* ones that were used when people entered the U.S. Can
someone please clarify this point please?"

Dear Carol, I have a copy of both manifests. One leaving Hamburg and the
other entering New York Harbor. They are definitely two different lists made
out by different people.
This is true for the manifests I have checked in the 1880's. Perhaps later
things changed. Wayne
