I was just looking over the new Ellis Island Records.org and found a few trips that my grandfather made when he was just a little older then I am now. It's a great site for searching the records of who came through the island (not just immigrants you know). It provide copies of the original ship manifests (in which they asked the passengers some pointed questions: such as "Polygamist? Anarchist?") and even pictures of some of the ships. Try it out and search for some relatives...
