Vicki’s note – Take the time to explore Stephen P. Morse’s One-Step Webpages. He makes shortcuts to access several resources for Genealogy, etc. You will want to go to his website http://www.stevemorse.org/
to see all of his valuable links to many sites, especially Ellis Island and Castle Garden. Or you can click on the green links below to each subject.
This site contains tools for finding immigration records, census records, vital records, and for dealing with calendars, maps, foreign alphabets, and numerous other applications. Some of these tools fetch data from other websites but do so in more versatile ways than the search tools provided on those websites.
