Here is a loooong shot for information; Go to Wikipedia site and then to Hapag-Lloyd. On their list read NGL-NDL. it tell of ships from these lines going from Hamburg-Bremerhafen etc and covers their history from1856. Perhaps you could write to them in Hamburg and ask if they have such records. We have to remember that Bremen used to destroy their own records years ago as a common practice and of course the war did it again. Bill Fehlinger-New Jersey
