There are some kind souls out there on the Internet who have access to passenger lists which are only available through paid subscription. If you can describe yourself as 'perplexed' then my guess is that you have a fine grasp of the English language, a large vocabulary and by deduction you are as wealthy as a oil baroness. So you can probably afford to subscribe to ancestry.com, lol.
Joking aside, some lists are available for free, so it is a case of making Google do the leg work, and search for passenger lists, destination port, name, year, and so on and so forth.
Best of luck
